  The terminal connector 28A of the portable music player 6A is a female connector that can be connected to the charging base connector 13 of the cradle device 2 with a music function. The terminal connector 28 </ b> A is disposed on the bottom surface portion 201 b of the outer case 201 at a position that is biased by a distance e from the center to one side in the longitudinal direction. The amount of deviation e corresponds to the amount of movement of the connector 13 and is set to substantially the same length. Thus, the attachment position of the terminal connector 28A is deviated from the center of the portable music player 6A because the outer case 201 is thin and the storage space is narrow, so that the space for storing the battery device and other devices is small. The result of the relationship.

  When the portable music player 6A is attached (set) to the cradle device 2 with a music function, the connector 13 is moved to the second position biased from the center to one side. Thus, by setting the connector 13 to the second position, even if the portable music player 6A is biased from the center, the terminal connector 28A is set at the approximate center of the cradle device 2 with music function. It is possible to eliminate the apparent imbalance due to the portable music player 6A being deviated from the center at the time of setting.

  The terminal connector 28B of the mobile phone 6B with music playback function is a female connector that can be connected to the charging base connector 13 of the cradle device 2 with music function. The terminal connector 28B is disposed at the center position on the bottom surface portion 211b of the outer case 211 so as to substantially coincide with the center thereof. As described above, the attachment position of the terminal connector 28B coincides with the center of the mobile phone 6B with the music playback function because the outer case 211 is thick and has a large storage space. This is because there is a relatively large space for storing the battery.

  When the cellular phone 6B with music playback function is attached (set) to the cradle device 2 with music function, the connector 13 is moved to the first position set at the center. In this way, by setting the connector 13 to the first position, the mobile phone 6B with the music playback function in which the terminal connector 28B is coincident with the center can be set at the approximate center of the cradle device 2 with the music function. It is possible to prevent the appearance of imbalance due to the deviation of the mobile phone 6B with the music playback function from the center at the time of setting.

  Further, the partition portion 102 of the charging base cover 61 has a shape corresponding to the notch portion 56 of the upper case 11. In other words, the partition portion 102 has a shape that can close the notch portion 56 with the same surface shape when assembled to the upper case 11.

This is done by inserting the screw shaft portion of the fixing screw 91 into the insertion hole 87 provided in the two bearing portions 84, 84 of the guide block 64, and screwing the tip into the screw hole 76 to fix it. The Thereafter, a leaf spring 95 is overlaid on the guide block 64, and two shaft urging portions 95b and 95b provided on both sides of the leaf spring 95 are interposed between the front and rear bearing pieces 84a and 84b provided on the respective bearing portions 84. At the same time, the holding hole 66 of the slide base 63 is closed by the ball biasing portion 95c provided at the front portion. Thereby, the steel ball 67 held in the holding hole 66 is pressed against the chassis 55 by the urging force of the sphere urging portion 95c.

  At this time, two elongated holes 74 are provided at predetermined positions at positions corresponding to the steel balls 67 of the charging stand support 58. Therefore, the steel ball 67 is fitted into one of the two long holes 74 and 74 to lock the slide base 63 with an appropriate force. The positions of the two long holes 74 and 74 are a first position and a second position for holding the connector 13 with a predetermined force. And the click feeling at the time of switching the position of the connector 13 between a 1st position and a 2nd position with the force at the time of the steel ball 67 jumping out of one long hole 74 and entering into the other long hole 74 is carried out. It is generated.

  Next, the chassis 55 in which the slide base 63 and the guide block 64 are assembled is housed in the recessed portion 23 a of the lower case 23. Then, after attaching the escutcheon 72 to the connector 13 fixed to the slide base 63, the charging stand cover 61 is overlaid on the terrace portion 57. In this superposed state, the lower case 23 is assembled to the upper case 11. At this time, the left and right speakers 14 and 15, the wiring board 110 on which a predetermined control circuit is mounted, and other necessary devices and mechanisms are stored in advance in the upper case 11.

  Thereafter, as shown in FIG. 2, the lower case 23 is faced below the upper case 11, and the partition portion 102 of the charging base cover 61 is fitted into the notch portion 56 of the upper case 11. Then, the lower case 23 and the upper case 11 are fastened and fixed from below the lower case 23 using a predetermined number of fixing screws. Thereby, as shown in FIG. 1, the assembling work of the cradle device 2 with a music function in which the charging stand is provided in the approximate center of the front surface is completed.

  The cradle device 2 with a music function assembled in this way can be used as shown in FIGS. 6 and 7, for example. FIG. 6 shows a state in which the portable music player 6A having the configuration shown in FIG. 8 is connected to the connector 13 provided on the charging stand 12 of the cradle device 2 with music function. In this case, the terminal-side connector 28A of the portable music player 6A is provided at a position deviated by a distance e from the center of the outer case 201 to one side in the width direction. Therefore, the connector 13 of the charging stand 12 is moved to the second position that is a position deviated from the center of the charging stand 12 to one side.

  As a result, the connecting position of the connector 13 and the connector 28A is deviated by a distance e from the center of the charging stand 12 to the one side, but the outer case 201 is placed at the center of the charging stand 12, that is, the center of the cradle device 2 with a music function. Can be arranged. For this reason, it is possible to prevent the appearance of unbalance when it is mounted on the charging stand 12, and to set the portable music player 6A in the center of the cradle device 2 with a music function in a balanced manner.

  FIG. 7 shows a state in which the mobile phone 6B with the music playback function having the configuration shown in FIG. 9 is connected to the connector 13 provided on the charging stand 12 of the cradle device 2 with the music function. In this case, the terminal-side connector 28B of the mobile phone 6B with the music playback function is provided at a position substantially coincident with the center of the outer case 211. For this reason, the connector 13 of the charging base 12 is moved to the first central position and is also set at the center of the charging base 12.

  Thereby, the mobile phone 6B with a music playback function can be arranged at the center of the charging stand 12. For this reason, it is possible to prevent the appearance of imbalance in appearance when the charging base 12 is mounted, and to set the mobile phone 6B with the music playback function with respect to the cradle device 2 with the music function in a balanced manner.

  In these cases, as shown in FIGS. 11 to 16, the back surface of the portable music player 6A or the portable telephone 6B with a music playback function is a bent portion 83 which is a contact portion of a support bar 81 showing a specific example of a support member. Support from the back side. In this case, when the portable music device mounted on the charging stand 12 is, for example, a portable music player 6A having a thin outer case, the support bar 81 is advanced as shown in FIG. The fixing position of the support bar 81 is adjusted so that substantially the entire surface of the portable music player 6A substantially contacts the entire back surface of the portable music player 6A. Further, when the portable music device attached to the charging stand 12 is, for example, a mobile phone 6B with a music playback function with a thick outer case, the support bar 81 is retracted and bent as shown in FIG. The fixing position of the support bar 81 is adjusted so that substantially the entire portion 83 comes into contact with substantially the entire back surface of the mobile phone with music playback function 6B.

  As described above, when the thickness of the portable music device placed on the charging stand 12 is different, the distance from the connector of the portable music device to the back supported is different, or the outer shape of the portable music device. Therefore, even when a plurality of models with different connecting connectors in the left-right direction are placed, the support member can be easily adjusted, and a cradle device with a music function that is excellent in design can be provided.

  11 to 13 show a state where the portable music player 6A is placed on the charging stand 12. FIG. In this case, the thickness T1 of the portable music player 6A is thin, and the distance S1 from the center of the connector 13 to the back surface of the exterior case 201 is short. Furthermore, the center C0 of the connector 13 is biased (offset) to the left side by a distance e with respect to the center TC of the outer case 201. FIGS. 17 to 19 correspond to FIGS. 11 to 13 and are diagrams for explaining the operation of the support bar 81 as a support member. 17 shows a guide block 64 fixed to the chassis 55, a support bar 81 slidably supported by the guide block 64, and two guide shafts 82 and 82 of the support bar 81. It is a top view showing the leaf | plate spring 95 to do. 18 is a front view showing the guide block 64, the support bar 81, and the leaf spring 95, and FIG. 19 is a side view.

  14 to 16 show a state in which the mobile phone 6B with a music playback function is placed on the charging stand 12. In this case, the thickness T2 of the mobile phone with music playback function 6B is thick (T2> T1), and the distance S2 from the center of the connector 13 to the back surface of the exterior case 211 is long (S2> S1). On the other hand, the center C0 of the connector 13 coincides with the center TC of the outer case 211. FIG. 20 corresponds to FIGS. 14 to 16 and is a plan view showing a state in which the support bar 81 as a support member is retracted.

  Next, the operation of the support bar 81 will be described with reference to FIGS. The two guide shafts 82 and 82 of the support bar 81 are slidably supported by bearing pieces 84a and 84b before and after the two bearing portions 84 and 84 of the guide block 64, respectively. At the same time, a biasing force PS is applied by the two shaft biasing portions 95b and 95b of the leaf spring 95. Therefore, when the support bar 81 slides, the friction coefficient μ1 between the guide shaft 82 and the two insertion holes 86, 86 and the friction coefficient between the guide shaft 82 and the shaft biasing portion 95 b of the leaf spring 95. Drag FR is generated by μ2.

  Now, as shown in FIG. 19, force FA or force FB is applied in the direction of arrow A or arrow B near the two guide shafts 82, 82 of the support bar 81. In this case, the support bar 81 can be easily moved and adjusted to an arbitrary position while maintaining a loss due to a moderately large frictional resistance.

  Here, as shown in FIGS. 12 and 15, the portable music player 6 </ b> A or the mobile phone 6 </ b> B with a music playback function is connected to the connector 13 on the charging stand side, and the back surface thereof is a bent portion 83 which is a contact portion of the support bar 81. Support from the side by. It is assumed that the user presses the operation keys 203 or 213 provided on the upper part of the portable music player 6A and the portable telephone 6B with a music playback function. Then, for the reason described later, the two guide shafts 82 and 82 of the support bar 81 are in a so-called “bite” state by the bearing pieces 84 a and 84 b before and after the two bearing portions 84 and 84 of the guide block 64, It is firmly fixed.

  As a result, the force by which the operation key 203 or the like of the portable music player 6A or the like is pressed is reliably received by the support bar 81, and is used as a force for operating the operation key 203 or the like without moving the portable music player 6A or the like backward. used. Therefore, it is possible to reliably operate the operation keys 203 and the like, and to make the operation feeling very good. Further, since an excessive mechanical force does not act on the terminal side connector 28A or 28B built in the lower part of the portable music player 6A or the like, the connector 28A or the like can be prevented from being damaged.

  Now, assuming that there is no support bar 81, the force of pressing the operation key 203 of the portable music player 6A is used to move the portable music player 6A backward. For this reason, even if the operation key 203 is pressed, the operation ends only by moving the portable music player 6A backward, or in some cases, the operation key 203 is barely pressed while moving the portable music player 6A backward. Used as power. As a result, the operation feeling becomes very bad. In addition, since an excessive mechanical force acts on the terminal-side connector 28A, there is a possibility that the charging base connector 13 and the terminal-side connector 28A are damaged.

  Thus, according to the cradle device 2 with a music function of the present invention, when adjusting the position of the support bar 81 that is the support member, the vicinity of the two guide shafts 82 and 82 that are the guide portions of the support bar 81. By operating, the support bar 81 can be easily moved to an arbitrary position. Further, the support bar 81 is firmly fixed when the portable music player 6A or the like is placed and supported on the charging stand 12, and when the operation key 203 or the like of the portable music player 6A or the like is pressed, the connectors 13, 28A and 28B are impossible. There is no force applied. Therefore, it is possible to prevent the connectors 13, 28A, 28B from being damaged and to press the operation keys 203, 213 with good feeling.

Next, the relationship of the force applied to each member such as the support bar 81 and the guide block 64 will be physically described. Now, to simplify the description, it is assumed that the guide shafts 82 originally located at the left and right positions of the support bar 81 are located at one position. Since the support structure of the two left and right guide portions of the support bar 81 is the same, the force relationship between the two portions is half that added to the entire support bar 81 by the two guide shafts 82 and 82 inserted through the left and right bearing portions. Can be thought of as acting.
Hereinafter, unless otherwise specified, the description of the force relationship will be made at one place of the bearing portion.

If a force 2FA is applied to the support bar (support member) 81, a force FA is applied to one guide shaft 82.
Here, in order to facilitate the description, the action of the force applied to the support bar 81 will be described in three types. The first is when a force is applied to the center line of the bearing hole 86 of the guide shaft 82 (when no rotational moment is generated), and the second is a force applied to a position away from the center line of the bearing hole 86 of the guide shaft 82. In the case (when a rotational moment is generated, of which, in the case 1 there is no spring force of the leaf spring), the third is a case where a force is applied to a position away from the center line of the bearing hole 86 of the guide shaft 82 (rotational moment) In the case 2 of which the spring force of the leaf spring is present).

No.1. When force is applied on the center line of the bearing hole 86 of the guide shaft 82 (when no rotational moment is generated)
19 and 27A, a force FA directed in the direction of arrow A is applied to the lower portion of the support bar 81 on the extended line of the center line of each bearing hole 86, 86 provided in the bearing pieces 84a, 84b before and after the guide block 64. In addition, when the force FA is equal to or greater than the drag force FR, the support bar 81 moves in the arrow A direction.

  In this case, in FIG. 27A, an urging force PS against the guide shaft 82 by the leaf spring 95 and the own weight W of the support bar 81 are applied to the lower surface of the bearing hole 86 at the support portion of the support bar 81. At this time, since the guide block 64 is balanced without being moved downward even if it receives the urging force PS and its own weight W, a reaction force R1 and a reaction force R2 are applied to the lower surface of each bearing hole 86. The reaction forces R1 and R2 are R1 + R2 = PS + W.

Further, when the friction coefficient generated between the guide shaft 82 and the bearing hole 86 is μ1, and the friction coefficient generated between the guide shaft 82 and the leaf spring 95 is μ2, the drag FR is
FR = μ1 ・ R1 + μ1 ・ R2 + μ2 ・ PS
= Μ1 (R1 + R2) + μ2 · PS
It becomes. Here, since R1 + R2 = PS + W,
FR = μ1 (PS + W) + μ2 · PS
It becomes.
When the urging force PS by the leaf spring 95 is much larger than the own weight W, W << PS,
FR = PS (μ1 + μ2) (1)
Therefore, the drag force FR is determined by the urging force PS by the leaf spring 95 and the friction coefficients μ1 and μ2.

  In actual operation, when the support bar 81 is adjusted according to the outer shape of the portable music device, the support bar 81 can be easily moved to an arbitrary position by pushing and pulling the lower part of the support bar 81. Become. Moreover, due to an appropriate loss based on the frictional resistance generated by the leaf spring 95, it does not move too much during adjustment. Further, since the effect of maintaining the state as it is when the adjustment is finished is also provided, there is an effect that the adjustment is very easy as compared with the conventional example.

No.2. When a force is applied to a position away from the center line of the bearing hole 86 of the guide shaft 82 (when a rotational moment is generated, of which, when there is no spring force of the leaf spring)
In an actual specific embodiment, the rotational moment M1 and the action of the leaf spring 95 are related, but here, in order to facilitate understanding, the state without the leaf spring 95 is considered and the action of only the rotational moment M1 is considered. .

  In FIG. 27B, when a force FC is applied to a position separated from the center line of the bearing hole 86 that supports the guide shaft 82 of the support bar 81 by a distance L1, a rotational moment M1 is generated. In the support bar 81, the guide shaft 82 is supported by the bearing hole 86 so as to be slidable in the axial direction, while the support bar 81 is rotated by the bearing portions 84 and 84 in the rotational direction. Never do. Therefore, it is considered that the support bar 81 has a rotational moment MR equivalent to the rotational moment M1 generated in the two bearing portions 84 and 84, and is balanced by the reaction force.

At this time, the rotational moment M1 generated by the force FC applied from the outside is
M1 = FC ・ L1
Suppose that the center of rotation O is between the two bearing holes 86, 86 located at the front and rear. When the distance between the two bearing holes 86, 86 is L2, the distance between the front bearing hole 86 and the rotation center O is X, and the distance between the rotation center O and the rear bearing hole 86 is L2-X, The rotational moment MR due to the reaction force R1 and reaction force R2 in the bearing holes 86, 86 is
MR = X.R1 + (L2-X) .R2
It becomes.

Further, since the guide block 64 does not move, the reaction force R1 and the reaction force R2 are balanced. That is,
R1 = R2
It is. Therefore,
MR = L2 / R1 = L2 / R2
It is. Since this is balanced with the rotational moment M1,
M1 = MR
M1 = L2 · R1 = L2 · R2
It is. Therefore,
R1 = R2 = M1 / L2 = (L1 / L2) FC
It becomes.

Furthermore, if the friction coefficient generated between the guide shaft 82 and the bearing hole 86 is μ1,
FR = μ1 ・ R1 + μ1 ・ R2
= 2μ1 ・ R1
= 2μ1 (L1 / L2) FC
It becomes. Therefore, when 2 μ1 (L1 / L2) is 1 or more, the more the force FC is applied from the outside, the more the support bar 81 moves. A so-called “bite-in phenomenon” occurs, and the support bar 81 is not moved by the external force FC.

Here, considering the case of L1 = L2,
R1 = R2 = FC
FR = 2μ1 ・ FC
It becomes. Therefore, if the value of the friction coefficient μ1 is 0.5 or more, the support bar 81 does not move due to a biting phenomenon.

3 When a force is applied to a position away from the center line of the bearing hole 86 of the guide shaft 82 (when a rotational moment is generated, of which, if there is a spring force of a leaf spring in part 2. )
Consider the case where the urging force PS by the leaf spring 95 is further applied from the second state.

  In FIG. 27C, it is assumed that the urging force PS by the leaf spring 95 is applied to an intermediate point between the two front and rear bearing holes 86 and 86 that support the guide shaft 82 of the support bar 81. In this case, in terms of rotational moment, if the rotational center O between the two bearing holes 86, 86 described in Part 2 is considered to be an application point of the urging force PS by the leaf spring 95, The rotational moment due to the force PS need not be considered, and as a result, it is the same as in the second case.

Further, an urging force PS by a leaf spring 95 is applied at an intermediate point between the two front and rear bearing holes 86 and 86 that support the guide shaft 82 of the support bar 81, and each bearing hole 86 has a PS / 2 force. Will be added. At this time, PS / 2 is added to the reaction force R2 on the rear side, while PS / 2 is subtracted from the reaction force R1 on the front side. Therefore, when the reaction force after the urging force PS is applied is R1 ′ and R2 ′, respectively,
R1 '= R1-PS / 2
R2 '= R2 + PS / 2
It becomes.

Here, when the friction coefficient generated between the guide shaft 82 and the leaf spring 95 is μ2, the drag FR is
FR = (μ1 · R1 ′) + (μ1 · R2 ′) + μ2 · PS
= Μ1 ・ R1 + μ1 ・ R2 + μ2 ・ PS
= 2μ1 ・ R1 + μ2 ・ PS
= 2μ1 (L1 / L2) FC + μ2 · PS
It becomes.
Therefore, in this case, the condition is easier to bite than the second state. Thereby, the function of the free rod mechanism is exhibited.

  Next, the operation of the charging stand connector 13 will be described in detail with reference to FIGS. 21 and FIG. 22, the connector 13 mounted on the slide base 63 moves to the right side when the cradle device 2 with music function is viewed from the front, and the charging stand 12 provided at the approximate center of the cradle device 2 with music function is shown. A state in which the center SC and the center CO of the connector 13 coincide is shown. 23 and 24, the connector 13 moves to the left when the cradle device 2 with music function is viewed from the front, and the center CO of the connector 13 is shifted to the left by the distance e with respect to the center SC of the charging stand 12. (Offset) state.

  As shown in FIG. 25, the charging stand support portion 58 of the chassis 55 is provided with three protrusions 121 having female screw portions 121 a into which the stepped screws 68 are screwed. By screwing the male screw portion 68a of the stepped screw 68 into the female screw portion 121a of each protrusion 121, the three stepped screws 68 are fixed at predetermined positions of the chassis 55. The stepped screw 68 is provided with a horizontal guide portion 122a and an upper guide portion 122b. The horizontal guide portions 122 a of the two stepped screws 68 are slidably inserted into the guide holes 65 of the slide base 63. Further, the interval V formed by the lower guide portion 121 b formed on the upper surface of the protruding portion 121 and the upper guide portion 122 b of the stepped screw 68 is formed to be slightly larger than the plate thickness U of the slide base 63.

  The slide base 63 is slidable in the left-right direction while being restrained with a predetermined gap in the up-down direction. The combination of the guide hole 65 of the slide base 63 and the stepped screw 68 is provided in two places, and the combination of the first side 63a that is one guide edge portion of the slide base 63 and the stepped screw 68 is provided in one place. By providing, the slide base 63 is restricted in position control in the vertical direction (z direction in FIG. 25) and in the front-rear direction (y direction in FIG. 25), and rotation around the x axis, y axis, and z axis. It is configured to be movable only (in the x direction in FIG. 25).

  Similarly, two elongated holes 74 are provided in the charging stand support 58 of the chassis 55. The slide base 63 is provided with a holding hole 66. When the slide base 63 moves to the left, the center of the holding hole 66 coincides with the center of the elongated hole 74 located on the left side. ing. When the slide base 63 moves to the right, the center of the holding hole 66 is made to coincide with the center of the long hole 74 located on the right side. The steel ball 67 described above is accommodated in the holding hole 66.

  The diameter of the holding hole 66 is slightly larger than the diameter of the steel ball 67, and the steel ball 67 can rotate or move in the vertical direction within the holding hole 66. On the other hand, the width of the two long holes 74, 74 is formed to be somewhat smaller than the diameter of the steel ball 67, and even when the center of the holding hole 66 and the center of the long hole 74 coincide, 67 is prevented from entering the elongated hole 74.

  In such a configuration, the ball biasing portion 95 c of the leaf spring 95 fixed to the guide block 64 extends above the holding hole 66. The ball urging portion 95 c of the leaf spring 95 is in contact with the upper portion of the steel ball 67 and urges the steel ball 67 toward the chassis 55. At this time, the steel ball 67 is locked to the edge of the long hole 74 provided in the chassis 55, and the slide base 63 is stopped by the urging force of the leaf spring 95. Therefore, in this state, the slide base 63 cannot move in the left-right direction.

  From this state, if the slide base 63 is moved by applying a force in the right direction (x direction), for example, the steel ball 67 fitted in the holding hole 66 with a slight clearance is also moved in the right direction. The power to go to is added. At this time, the steel ball 67 is pressed by the ball urging portion 95c of the leaf spring 95 and engaged with one of the long holes 74 of the chassis 55, but is stopped from the side (right direction). When the force is applied, the plate spring 95 moves upward against the urging force of the leaf spring 95 while moving in the right direction. FIG. 26A and FIG. 26B show this state.

  Further, when a force in the right direction is applied to move the slide base 63 in the right direction, the steel ball 67 is now moved by the biasing force of the leaf spring 95 when the steel ball 67 comes to the position of the other long hole 74. Is engaged with the long hole 74 as if entering the long hole 74 itself. In this manner, the steel ball 67 moves to a position where the center of the holding hole 66 and the center of the elongated hole 74 coincide with each other while moving the slide base 63, and is stopped at that position. FIG. 26B and FIG. 26C show this state. By such an operation of the steel ball 67, a click feeling when moving the slide base 63 is obtained, and the movement of the slide base 63 can be clearly recognized.

  Such an operation is the same when the slide base 63 is moved in the reverse direction (left direction). Similarly, the steel ball 67 moves from one elongated hole 74 to the other elongated hole 74 together with the holding hole 66 of the slide base 63. As a result, the same click feeling can be generated and the movement of the slide base 63 can be clearly recognized. Then, coupled with a modest movement, it is possible to obtain an operational feeling with a pleasant click feeling.

  Thus, in the state shown in FIGS. 14 to 16 and FIG. 21, the center CO of the charging base connector 13 and the center SC of the cradle device 2 with music function coincide. As described above, when the center TC of the terminal-side connector 28B of the mobile phone (mobile music device) 6B with the music playback function is aligned with the center SC of the main body 10 of the cradle device 2 with the music function, the connector is used at this position. By using 13, it is possible to maintain the beauty of the design without causing an apparent imbalance.

  Further, in the state shown in FIGS. 11 to 13 and FIG. 23, the center CO of the charging base connector 13 is shifted to the left by a distance e with respect to the center SC of the cradle device 2 with music function (offset). Thus, even when the center TC of the terminal-side connector 28A of the portable music player (portable music device) 6B is shifted to the left by the distance e with respect to the center SC of the main body 10 of the cradle device 2 with a music function, By using the connector 13 at this shifted position, the beauty of the design can be maintained without causing an apparent imbalance.

  11 to 16, the charging base cover 61 is provided with a rectangular through hole 103, and the connector 13 passing through the through hole 103 is movable in the left-right direction. In this case, since the through hole 103 is larger than the connector 13, when the connector 13 moves, a hole is opened on the opposite side. A member for preventing this is the escutcheon 72. The escutcheon 72 has a flange portion 72 b that is larger than the movement range of the connector 13. Since the escutcheon 72 moves together with the connector 13, the through-hole 103 can be completely closed even when the connector 13 is moved, and the inside can always be hidden.

  As shown in FIGS. 21 and 23, the chassis 55 is provided with a position detector 130 that detects the movement of the slide base 63. The probe (detection unit) 131 of the position detector 130 is disposed so as to face one end of the slide base 63 in the moving direction. Now, as shown in FIG. 21, when the slide base 63 moves to the right, the probe 131 is pressed and the switch is turned on. Further, as shown in FIG. 23, when the slide base 63 moves to the left, the pressing of the probe 131 is released, and the switch is turned off. Based on the position information of the slide base 63 generated from the position detector 130, for example, the type of portable music device attached to the charging stand 12 is displayed on the cradle device 2 with a music function so that the portable It is possible to visually recognize the type of music device. Of course, the use form of the position information is not limited to this embodiment.

  28A to 28C show second to fourth examples of the support member according to the cradle device with music function of the present invention. A support member 141 shown in FIG. 28A shows a second example of the support member, and includes a guide portion made up of two guide shafts 142 and 142 and a contact portion made up of a flat plate-like support plate 143. Has been. The two guide shafts 142 and 142 are arranged in parallel with each other at a predetermined distance, and the lower end portion of the support plate 143 is connected to one end of each of the guide shafts 142 and 142. One end of each of the two guide shafts 142 and 142 is formed with a connecting portion 142a by being bent at an appropriate length from the tip. A support plate 143 is integrally fixed to each connecting portion 142 a of the two guide shafts 142 and 142. The support plate 143 is made of a rectangular plate having a relatively wide width so that it can come into contact with a portable music device over a wide area.

A music signal reproduced from the internal memory or the like by the music player 6A or the like is input via the charging stand connection terminal. As a result, music is output from the left speaker 14 and the right speaker 15 based on the input music signals.

(5) Circuit Configuration of Cradle Device with Music Function and AC Adapter Next, the circuit configuration of the cradle device with music function 2 and the AC adapter 3 will be described with reference to FIGS. As shown in FIG. 4, the cradle device 2 with music function is totally controlled by an MPU (Micro Processing Unit) 40. The MPU 40 is configured to operate as a whole based on DC power supplied from the AC adapter 3 via the DC cable 4.

  The cradle device 2 with a music function is supplied from a connector 28A (or 28B) having a terminal connection terminal of a portable music player 6A or a mobile phone 6B with a music playback function connected via a connector 13 having a charging stand connection terminal. The music signal to be played is input to the input selector 41. Music data supplied from an external portable music device 56 connected via the line input terminal 26 is also input to the input selector 41.

  The input selector 41 preferentially selects a music signal supplied from the portable music player 6A or the portable telephone 6B with a music playback function via the connector 13 as a default and sends it to an A / D (Analog / Digital) converter 42. It is made like that. Further, the MPU 40 preferentially selects a music signal supplied from the external portable music device 6C based on the key signal S1 input in response to the user's pressing operation on the function switch 16, and sends it to the A / D converter 42. It can be sent out. In other words, the cradle device 2 with a music function can selectively switch either a music signal from the portable music player 6A or the like or a music signal from the external portable music device 56 in response to a pressing operation on the function switch 16. Has been made.

  The A / D converter 42 converts the audio signal into digital music data MD 1 and sends the music data MD 1 to the digital signal processor 43. The digital signal processor 43 performs predetermined digital signal processing on the music data MD1 and then sends it to the class D amplifier 44 and the digital interface transmitter 45. The class D amplifier 44 amplifies the music data MD1 subjected to the digital signal processing, and outputs the sound corresponding to the left channel music signal and the right channel music signal obtained as a result of the left speaker 14 and the right channel. Output from each speaker 15.

  The digital interface transmitter 45 converts the music data MD1 subjected to the digital signal processing into music data SMD1 in a serial data format, and sends it to the superimposing circuit 46. Note that the MPU 40 of the cradle device 2 with music function outputs the audio data MD1 output from the digital signal processor 43 based on the control signal S2 input corresponding to the pressing operation of the user with the volume up button 17 and the down button 18. The volume level can be adjusted. Incidentally, the MPU 40 can control the lighting of the power display LED 19, the line-in display LED 20, and the surround display LED 21 by outputting an LED control signal S3 corresponding to the operation state of the cradle device 2 with a music function.

  The AC adapter 3 inputs AC power of AC 100 [V] supplied from the commercial AC power source to the switching power circuit 50 of the power amplifier unit 32. The switching power supply circuit 50 converts AC power of AC 100 [V] into DC power DP of DC 12 [V], and supplies the DC power DP to the MPU 52, the receiver 53, and the class D amplifier 54 via the separation circuit 51.

  Further, the AC adapter 3 converts the DC power DP 12 [V] supplied from the switching power supply circuit 50 from the DC terminal 55 via the separation circuit 51 to the DC power DP via the DC cable 4 and the DC input terminal 25. Is supplied to the cradle device 2 with a music function. As a result, the portable music player 6A and the mobile phone 6B with a music playback function are charged via the connector 13 (connection terminal for charging stand) 13.

  By the way, the cradle device 2 with a music function receives a direct current from the AC adapter 3 via the DC cable 4, and transmits the music data SMD 1 to the AC adapter 3 by superimposing the direct current on the direct current by the superimposing circuit 46. It is made like that. In this case, as shown in FIG. 5, in the cradle device 2 with a music function, the music data SMD1 is transmitted via the DC cable 4 through the capacitor C1, and the music data SMD1 transmitted via the DC cable 4 is transmitted through the AC adapter 3. Is input to the separation circuit 51 via the capacitor C2.

  In this way, the AC adapter 3 can receive the music data SMD1 from the cradle device 2 with a music function via the DC cable 4 by the capacitor C1 and the capacitor C2. As a result, the AC adapter 3 separates the direct current and the music data SMD1 by the separation circuit 51, extracts only the music data SMD1, and sends it to the receiver 53. The receiver 53 restores the original music data MD1 by, for example, demodulating the music data SMD1, and filters only the low frequency component of the restored music data MD1. As a result, the low sound region component MD1L can be obtained, and this low sound region component MD1L is sent to the class D amplifier 54. The class D amplifier 54 amplifies the low sound region component MD1L and outputs a low sound corresponding to the low sound region component MD1L from the subwoofer 33.

  Furthermore, the cradle device 2 with music function performs digital signal processing on the music data MD1 reproduced and supplied by the portable music player 6A or the portable telephone 6B with music reproduction function by the digital signal processor 43, and then stores it in the memory 47. Has been made to get. As a result, the cradle device 2 with a music function can also read the music data MD1 from the memory 47 and output the sound corresponding to the music data MD1 from the left speaker 14 and the right speaker 15 via the class D amplifier 44. It is made like that.

  As described above, the cradle device 2 with a music function can store many types of music data MD1 in the memory 47, reproduce the music data MD1, and output the music data MD1 from the left speaker 14 and the right speaker 15. Therefore, even when the portable music player 6A and the mobile phone 6B with music playback function are not connected, the cradle device 2 with music function can itself be a playback means for the music data MD1 and can also be an audio output means. Has been made.

  In addition, the cradle device 2 with a music function is configured so that the MPU 40 can detect that an incoming call has been made to the mobile phone 6B with a music playback function connected via a connector (charging terminal connection terminal) 13. . As a result, when the incoming call of the mobile phone 6 with a music playback function is detected while the music data MD1 is being played and output from the left speaker 14 and the right speaker 15, the volume level of the music data MD1 is detected via the digital signal processor 43. The ring tone can be output from the left speaker 14 and the right speaker 15. Thereafter, in the cradle device 2 with music function, a transition is made to the hands-free state, and after the ringtone is output, the other party's voice can also be output from the left speaker 14 and the right speaker 15.

  In the above configuration, in the acoustic system 1, the sound corresponding to the music data MD1 reproduced by the portable music player 6A connected via the connector 13 of the cradle device 2 with music function or the mobile phone 6B with music reproduction function is selected. Since the high frequency range can be output from the left speaker 14 and the right speaker 15 and the low frequency range of the sound corresponding to the music data MD1 can be output from the subwoofer 33 of the AC adapter 3, it can be output only from the left speaker 14 and the right speaker 15. Then, the subwoofer 33 can sufficiently cover the low frequency range that cannot be output.

  At this time, in the acoustic system 1, the cradle device 2 with music function in which the left speaker 14 and the right speaker 15 are mounted is installed on, for example, a table, and the AC adapter 3 in which the subwoofer 33 is accommodated in the main body 31. Can be provided under the table to provide a rich acoustic environment from the low range to the mid-high range without making the user feel the presence of the subwoofer 33 at all.

  In particular, since the AC adapter 3 is configured so that the subwoofer 33 outputs only a low sound range without directivity, the subwoofer 33 can be concealed inside the main body 31, thereby preventing the user from seeing it. Thus, it is possible to feel as if the sound from the low sound range to the mid-high sound range is output only by the left speaker 14 and the right speaker 15 of the cradle device 2 with music function.

  The AC adapter 3 outputs only the sound of the low-frequency component MD1L tuned at the port 35, and the subwoofer 33 is entirely covered by the main body 31, so that the medium / high sound that cannot be completely filtered by digital filtering. Even if the frequency range is temporarily output from the subwoofer 33, the mid-high frequency range hardly leaks from the main body 31 to the outside, and only the low frequency range can be reliably output by the mechanical filtering structure. .

  In the acoustic system 1, not only can the DC power DP be supplied from the AC adapter 3 to the cradle device 2 with music function by the DC cable 4 that is a power supply line, but also the AC adapter 3 can be supplied from the cradle device 2 with music function. By adopting a structure capable of transmitting music data SMD1 to the mobile phone, it is not necessary to provide two power lines for DC power DP and two signal lines for music data SMD1, thereby simplifying the overall structure. it can. Therefore, in the acoustic system 1, the cradle device 2 with a music function and the AC adapter 3 can be connected by a general DC cable 4, so that the subwoofer 33 is not mounted instead of using the AC adapter 3. It is also possible to connect a general AC adapter (not shown) by the DC cable 4, and the usability can be further improved.

  According to the above configuration, in the acoustic system 1, the middle and high frequency ranges are output by the left speaker 14 and the right speaker 15 of the cradle device 2 with music function, and the low range is output by the subwoofer 33 housed in the AC adapter 3. Therefore, it is possible to provide an expressive listening environment without increasing the size of the cradle device 2 with music function by the subwoofer 33 and making the user feel the presence of the subwoofer 33. .
