A plurality of recesses 2E are sequentially formed at a predetermined pitch along the longitudinal direction of the neck hook 2 on the bottom surface 2D. In addition, an elongated hole-like opening 2G extending from the neck one end position to the one end side boundary position is formed on a side surface 2F facing the outside of the neck hanging portion 2 (hereinafter referred to as an outer surface). An internal hole is exposed to the outside through the portion 2G.

  Further, the other end side of the speaker cable 8 inserted into the neck hook 2 is individually covered with a right speaker conductive wire and a left speaker conductive wire, for example, from one cable near the one end side boundary. The right speaker cable (hereinafter referred to as the right speaker cable) 8A and the left speaker cable (hereinafter referred to as the left speaker cable) 8B are branched. Incidentally, the branch portion of the speaker cable 8 is fixed in the neck portion 2.

  The right speaker cable 8A is pulled out from the inside of the neck hook portion 2 through the opening 2G, and the tip portion (that is, the portion opposite to the branch portion) is electrically connected to the right speaker of the right speaker portion 5. Connected. Incidentally, the cable 8A for the right speaker has elasticity, for example, with a coating formed of a resin material such as insulating rubber. Further, the right speaker cable 8A is selected such that the length from the branch position to the tip of the left speaker cable 8B is longer than the length from the one end side boundary position of the neck hook 2 to the neck one end position.

  Therefore, in the right speaker cable 8A, for example, when the right speaker portion 5 moves from the neck end one end position side to the one end side boundary position side, the distal end portion gradually moves from the neck end one end position side to the one end side boundary position side. When moved while being pulled, the folded portion in the direction of the one end side boundary position of the right speaker cable 8A that has been routed in the direction of the neck end one end position is changed from the neck end one end position side to the one end side boundary position side.

It is exposed.

  Further, the left speaker cable 8B of the speaker cable 8 inserted into the neck hook 2 is routed from the one end side arm portion 2B to the other end side arm portion 2C through the body portion 2A. The left speaker cable 8B is pulled out from the inside of the neck hook portion 2 through the opening 2J, and the tip portion (that is, the portion opposite to the branch portion) is electrically connected to the left speaker of the left speaker portion 7. Connected.

  Incidentally, the left speaker cable 8B is also elastic, for example, with a coating formed of a resin material such as insulating rubber. The left speaker cable 8B is selected such that the length from the branch position to the tip of the right speaker cable 8A is longer than the length from the one end side boundary position to the other end side boundary position of the neck hook portion 2. .

  Accordingly, in the left speaker cable 8B, for example, when the left speaker portion 7 is moved from the other end side boundary position side to the neck end other position side, the distal end portion is moved from the other end side boundary position side to the neck end other position. When it is moved while being gradually pulled to the side, the folded portion of the left speaker cable 8B that has been routed in the direction of the other end side boundary position in the direction of the neck contact other end position from the other end side boundary position side. While gradually displacing to the other end position side of the neck, the base portion side as well as the tip portion is pulled out from the inside of the neck hook portion 2 to the outside.

  Further, the left speaker cable 8B has, for example, a front end portion of the left speaker portion 7 that has moved from the neck end other end position side to the other end side boundary position side and the other end side boundary position from the neck end other end position side. When it moves while being gradually pushed to the side, it gradually displaces the folded part from the other end position side of the neckband to the boundary position side of the other end, while moving from the base part side to the tip part side from the outside to the inside of the neck hanging part 2 Is stored.

  By the way, the right speaker unit 5 and the left speaker unit 7 are similarly configured. Therefore, hereinafter, the configuration of the right speaker unit 5 will be described, and the description of the configuration of the left speaker unit 7 will be omitted. As shown in FIG. 4, the right speaker unit 5 has the substantially flat box-shaped casing 4 as described above, and the top plate 4A of the casing 4 has a plurality of sound emitting holes 4B having a grid pattern. It is drilled in a shape. The casing 4 is provided with a neck portion insertion hole 4E on the lower side of the center of the opposite side wall 4C and the other side wall 4D.

  The casing 4 is inserted with the neck hook 2 in order from the neck hook insertion hole of one side wall 4C through the internal space to the neck hook insertion hole 4E of the other side wall 4D. As a result, the housing 4 holds the right speaker portion 5 so as to be movable along the neck hook portion 2 with respect to the neck hook portion 2.

  Incidentally, the width of the neck hook portion insertion hole 4E formed in each of the one side wall 4C and the other side wall 4D is selected to be wider than the width of the neck hook portion 2. As a result, the right speaker portion 5 extends along the neck hook portion 2 inserted from the neck hook portion insertion hole of one side wall 4C of the housing 4 into the neck hook portion insertion hole 4E of the other side wall 4D through the internal space. While the linear part of the neck hook part 2 can be moved, an arcuate part (that is, a part closer to one end of the neck hook part than the neck abutting end position in the body part 2A) can also be moved. .

  As shown in FIG. 5, the housing 4 is provided with a partition plate 4F parallel to the top plate 4A, and two upper and lower layers of internal spaces 20 and 21 are formed through the partition plate 4F. In this case, the neck hooking portion insertion hole 4G of one side wall 4C and the neck hooking portion insertion hole 4E of the other side wall 4D communicate with a lower inner space (hereinafter referred to as a lower inner space) 21. . Thereby, the neck hook 2 is inserted into the lower internal space 21 through the neck hook insertion hole 4G of the one side wall 4C and the neck hook insertion hole 4E of the other side wall 4D.

  Further, a columnar leaf spring holding portion 4J is suspended from a bottom plate inner surface 4H of the housing 4 which is a bottom surface of the lower internal space 21. The leaf spring holding portion 4J has one surface of the flat body portion 22A of the leaf spring 22 parallel to the bottom plate inner surface 4H and close to the bottom surface 2D of the neck hook portion 2 inserted through the lower inner space 21. One end side of the body portion 22A of the leaf spring 22 is held. The leaf spring 22 is formed with a substantially trapezoidal fitting portion 22B that protrudes to one side so that a part of the body portion 22A is folded back to one end side on the other end side of the body portion 22A.

  In this case, the leaf spring 22 has one end side of the body portion 22A held by the leaf spring holding portion 4J as a fixed end and the fitting portion 22B as a free end. For example, in the state where no external force is applied to the fitting portion 22B, the leaf spring 22 is flattened while keeping one surface of the body portion 22A parallel to the bottom plate inner surface 4H. On the other hand, for example, when an external force is applied to the leaf spring 22 such that the fitting portion 22B is pressed downward (ie, in the direction from the partition plate 4F side to the bottom plate inner surface 4H), the body portion 22A has an arcuate shape. The fitting portion 22B is bent to approach the bottom plate inner surface 4H. However, at this time, the leaf spring 22 is biased upward so that the fitting portion 22B is separated from the bottom plate inner surface 4H and close to the partition plate 4F due to the spring property so as to return the body portion 22A to the original flat state.

  Further, the leaf spring 22 is selected such that the height from one surface of the body portion 22A to the top of the fitting portion 22B is slightly longer than the depth of the concave portion 2E of the neck hook portion 2. Further, the concave portion 2E of the neck hook portion 2 has one and the other side surfaces in the concave portion 2E are edges with the bottom surface 2D (hereinafter referred to as the trapezoidal shape) so as to match the shape of the fitting portion 22B of the leaf spring 22 (ie, trapezoidal shape) The interval is increased as the concave edge is increased, and the interval is inclined so that the bottom of the recess 2E (hereinafter referred to as the concave bottom) is decreased.

  Accordingly, as shown in FIGS. 6 (A) and 6 (B), when the fitting portion 22B faces the concave portion 2E of the bottom surface 2D of the neck portion 2, the leaf spring 22 is in a state where the body portion 22A is flattened. The fitting portion 22B is inserted into the recess 2E to be fitted. In this manner, the leaf spring 22 must be applied with any external force for moving the leaf spring 22 with respect to the housing 4 of the right speaker portion 5 in a state of being fitted to any one of the plurality of recesses 2E of the neck portion 2. For example, the fitting of the fitting portion 22B with respect to the one recess 2E is maintained. Accordingly, the leaf spring 22 can fix the right speaker portion 5 (that is, the housing 4) at a desired arrangement position of the neck hook portion 2 together with the concave portion 2 </ b> E of the neck hook portion 2.

  Further, the leaf spring 22 can be moved in any desired direction (that is, in the direction toward the central portion of the neck hanging portion 2 or the neck hanging portion so that the casing 4 of the right speaker portion 5 moves along the neck hanging portion 2). When pressed in the direction toward one end), one wall surface on the moving direction side is pressed against the corresponding wall surface in the recess 2E of the neck portion 2 in one and the other wall surfaces of the fitting portion 22B. Then, when the housing 4 of the right speaker unit 5 is further pushed in the moving direction, the leaf spring 22 causes the wall surface on the moving direction side of the fitting portion 22B to be a neck hanging portion according to the external force applied to the housing 4. The body portion 22A is bent into a bow shape while sliding toward the concave edge on the corresponding wall surface in the second concave portion 2E, and thus the fitting portion 22B is pulled out from the concave portion 2E.

  Accordingly, the leaf spring 22 can move the casing 4 of the right speaker unit 5 in the moving direction along the neck hook 2. However, the leaf spring 22 presses a part of the top of the fitting portion 22 against the bottom surface 2D of the neck portion 2 in a state where the body portion 22A is bent in a bow shape even if the fitting portion 22 comes out of the recess 2E. It is energizing upward. For this reason, the leaf spring 22 has a recessed portion 2E adjacent to the recessed portion 2E from which the fitting portion 22B has moved out by moving the housing 4 of the right speaker portion 5 along the neck portion 2 in the moving direction. , The body portion while sliding one wall surface of the fitting portion 22B on the side opposite to the moving direction to the concave bottom side on the corresponding wall surface in the adjacent concave portion 2E. 22A is returned to the original flat state, and the fitting portion 22B is inserted into the adjacent recess 2E to be fitted.

  That is, the leaf spring 22 has the recesses 2E that are sequentially adjacent to each other along the moving direction while the casing 4 of the right speaker unit 5 is pushed in the desired moving direction along the neck hanging part 2. While the fitting portions 22B are sequentially fitted therein, the arrangement position of the right speaker portion 5 (that is, the housing 4) with respect to the neck portion 2 is displaced at the formation pitch of the concave portions 2E. The leaf spring 22 has a right speaker portion 5 (that is, a housing) with respect to the neck hook portion 2 in a state where the fitting portion 22B is fitted into any one of the plurality of concave portions 2E of the neck hook portion 2. When the movement of the body 4) is stopped, the right speaker portion 5 (that is, the housing 4) is fixed to the neck portion 2 with the fitting portion 22B fitted in the one recess 2E. Thus, the leaf spring 22 can arbitrarily adjust the arrangement position of the right speaker portion 5 with respect to the neck hook portion 2 together with the plurality of recesses 2E of the neck hook portion 2.

  Furthermore, a cable insertion hole 4FX is formed at a predetermined position in the partition plate 4F (FIG. 5) inside the housing 4. The right speaker cable 8A pulled out from the neck portion 2 in the lower internal space 21 is inserted into the upper internal space (hereinafter referred to as the upper internal space) by inserting the distal end side thereof into the cable insertion hole 4FX of the partition plate 4F. Called 20).

  Further, the housing 4 is accommodated in the upper internal space 20 with the right speaker 23 facing the diaphragm 4A. The right speaker 23 is electrically connected to a right speaker cable 8 </ b> A drawn into the upper internal space 20. As a result, the housing 4 can emit sound from the right speaker 23 via the diaphragm, and can output the emitted sound to the outside via the plurality of sound emitting holes 4B of the top plate 4A. Has been made.

  Incidentally, the insertion portion of the right speaker cable 8A is fixed in the cable insertion hole 4FX of the partition plate 4F. Thereby, when the right speaker cable 8 </ b> A is pulled out from the neck hanging portion 2 or stored when the housing 4 moves along the neck hanging portion 2, the right speaker 23 is connected to the right speaker 23. The connection portion of the cable 8A is prevented from being pulled and disconnected.

  As shown in FIG. 7, the cable holding portion 11 has a hole for fixing the strap string 10 to the one end surface 11A of the one end surface 11A and the other end surface 11B facing each other (hereinafter referred to as a strap fixing hole). 11C is drilled. The cable holding portion 11 is fixed by inserting the other end of the strap 10 into the strap fixing hole 11C.

  Further, the cable holding portion 11 is provided with a through hole (hereinafter referred to as a cable holding hole) 11D for holding the speaker cable 8 from the one end face 11A to the other end face 11B. And the cable holding part 11 has the cable one end side of the speaker cable 8 inserted in the cable holding hole 11D. By the way, the inner diameter of the table holding hole 11D is selected to be slightly smaller than the diameter of the speaker cable 8. The speaker cable 8 has an elastic covering as described above.

  Thereby, the cable holding part 11 is hold | maintained so that the circumference | surroundings of the insertion part of the speaker cable 8 may be tightened slightly by the cable holding hole 11D. And if the cable holding part 11 moves to the cable one end side of the speaker cable 8 and a force of a certain level or more acts on the cable holding part 11 and / or the speaker cable 8, the speaker corresponding to the cable holding hole 11D is responded accordingly.

As a result, the housing 62 can emit reproduced sound from the right speaker 72 through the diaphragm, and can output the reproduced sound that has been emitted to the outside through the plurality of sound emitting holes 62B of the top plate 62A. Has been made to get.

  Incidentally, the insertion portion of the right speaker cable 66A is fixed in the cable insertion hole 62G. Thus, the housing 62 prevents the connection portion of the right speaker cable 66A to the right speaker 72 from being pulled and disconnected when moved along the neck strap 61A.

  Further, the neck hook string insertion hole 62J of the one side wall 62C and the neck hook string insertion hole 62E of the other side wall 62D communicate with the lower inner space 71 in the housing 62. Accordingly, the neck strap 61A is inserted into the lower inner space 71 through the neck strap insertion hole 62J of the one side wall 62C and the neck strap insertion hole 62E of the other side wall 62D.

  Further, a rectangular opening 62 </ b> M is formed on the inner surface 62 </ b> K of the bottom plate of the housing 62 that becomes the bottom surface of the lower internal space 71. A substantially L-shaped string stopper 73 is attached to the casing 62 so as to close the opening 62M.

  In this case, as shown in FIG. 21, the string-fastening portion 73 includes a plate-like cord-locking main body 73A having a width slightly narrower than the width of the opening 62M. A substantially U-shaped notch 73AX is formed at one end of the main body (hereinafter referred to as the main body longitudinal direction). Further, the string presser 73B provided at the other end in the longitudinal direction of the main body (hereinafter referred to as the other end of the main body) on the one surface 73AY of the string fixing main body 73A is formed in a substantially wedge shape and has an inclined wall surface 73BX. The cord main body 73A is directed to one end of the main body. Further, a rotation shaft 73C is provided at the base portion of the string presser 73B in parallel with the width direction of the string fixing main body 73A (hereinafter referred to as the main body width direction).

  On the other hand, as shown in FIG. 22, the bottom plate inner surface 62 </ b> K of the casing 62 has one end (hereinafter referred to as an opening end) side of the longitudinal direction of the opening 62 </ b> M (hereinafter referred to as the opening longitudinal direction). A pair of string stop abutment plates 62P and 62Q are provided at the edges of both corners so as to project into the opening 62M from both corners. Further, the bottom plate inner surface 62K of the housing 62 has both edges in the width direction of the opening 62M (hereinafter referred to as the opening width direction) and the other end in the opening longitudinal direction (hereinafter referred to as the other end of the opening). A pair of bearing portions 62R and 62S protrudes on the side called.

  In the cord stopper 73, the rotation shaft 73C is pivotally supported by the pair of bearings 62R and 62S of the housing 62. Thus, the cord stopper 73 can be rotated about the rotation shaft 73C in the closing direction in which the opening 62M is closed by the cord stopper main body 73A and in the opening direction in which the opening 62M is opened. Yes.

  When the cord stopper 73 actually rotates in the closing direction, one end 73AY of the one surface 73AY of the cord anchoring main body 73A (that is, the two corners on one end of the main body on the one surface 73AY) is paired with a pair of cord stopper abutment plates 62P and 62Q. The opening 62M is closed by the strap main body 73A. That is, the string stopper 73 causes the string retainer 73B to enter the lower inner space 71 of the housing 62 when the opening 62M is closed by the string anchor main body 73A. Incidentally, when the opening 62M is closed, the string stopper 73 prevents the other surface 73AZ (FIG. 20) of the string anchor main body 73A from protruding outward from the bottom plate outer surface 62T (FIG. 20) of the casing 62. The thickness of the main body 73A is selected.

  Further, when the opening 62M is closed, the cord stopper 73 brings the top 73BY of the cord retainer 73B closest to the partition plate 62H in the housing 62, and the neck strap between the top 73BY and the partition plate 62H. The height of the string presser 73B (that is, the length from one surface 73AY to the top 73BY of the string fixing main body 73A) is selected so as to form a gap narrower than the thickness of 61A. As a result, when the opening 62M is closed, the cord stopper 73 is sandwiched between the partition plate 62H in the housing 62 and the top 73BY of the cord presser 73B so as to crush the neck strap 61A, and thus the neck strap The right speaker portion 63 is fixed so as not to move with respect to 61A.

  Further, in the cord stopper 73, a rotation shaft 73C provided at the base portion of the cord presser 73B is positioned closer to one end of the main body than a perpendicular line from the top 73BY of the cord presser 73B to the one surface 73AY of the cord stopper main body 73A. It is provided as follows. Thus, when the opening 62M is closed, the cord stopper 73 crushes and holds the neck strap 61A directly above the rotation shaft 73C (that is, on the vertical line from the top 73BY to the one surface 73AY of the strap main body 73A). Compared to the case where the rotation shaft 73C is positioned), the neck strap 61A is crushed between the partition plate 62H and the top 73BY of the strap retainer 73B in a state of being biased to rotate in the closing direction. Thus, the arrangement position of the right speaker portion 63 with respect to the neck strap 61A is not easily removed.

  Furthermore, the string stopper 73 is formed in a bow shape at the top 73BY of the string retainer 73B. As a result, when the strap stopper 73 closes the opening 62M and sandwiches the neck strap 61A between the partition plate 62H and the top 73BY of the strap retainer 73B so as to crush the neck strap 61A, To prevent damage.

  On the other hand, as shown in FIG. 23, when the string stopper 73 is pulled so that a finger or the like is hung on the notch 73AX with the opening 62M closed and one end of the string anchor body 73A is separated from one end of the opening, It rotates in the opening direction around the rotation shaft 73C. At this time, the string stopper 73 separates the top 73BY of the string retainer 73B from the partition plate 62H in the casing 62 and releases the neck strap 61A from being caught. As a result, the cord stopper 73 can move the casing 62 along the neck strap 61A.

  Then, when the cord stopper 73 is rotated in the closing direction again with the housing 62 disposed at the desired position of the neck strap 61A, the neck strap is placed between the partition plate 62H and the top 73BY of the cord presser 73B. 61A is inserted again. As a result, the cord stopper 73 fixes the right speaker unit 63 to a desired arrangement position of the neck strap 61A. In this way, the string stopper 73 can arbitrarily adjust the arrangement position of the right speaker section 63 with respect to the neck strap 61A.

  As shown in FIG. 18, a pair of movement restricting portions 75A and 75B made of a convex resin are provided on the neck strap surface 61AQ of the neck strap 61A near one end and the other end of the neck strap central portion 61AK. Is formed. The neck strap insertion holes 62J and 62E provided in the housing 62 of the right speaker section 63 are selected such that the slit-like gap is substantially equal to the thickness of the neck strap 61A. Accordingly, when the casing 62 moves from one end side to the other end side, the neck strap 61A causes the edge portion of the neck strap insertion hole 62J of the casing 62 to abut against the movement restricting portion 75A, and the movement of the casing 62A is performed. It is regulated. Further, the neck strap 61A has the edge of the neck strap insertion hole 62E of the casing 62 abutted against the mouth of the one end side bag portion 61AR when the casing 62 moves from the other end side to the one end side. The movement is regulated.

  In this way, the neck strap 61A has a movement range of the right speaker portion 63 (that is, the casing 62) in the neck strap one end portion 61AM (that is, an adjustment range of the arrangement position of the right speaker portion 63 with respect to the neck strap 61A). Is regulated. Thereby, although the arrangement position of the right speaker unit 63 is adjustable, the right hanging speaker 61A is arranged so that the right speaker unit 63 is arranged on the back side of the user's neck or on the chest, and the right speaker is arranged. It can be avoided that the diaphragm 72 is directed in a direction different from the right ear side and it becomes difficult to hear the reproduced sound.

  Incidentally, the length of the right speaker cable 66A is selected to be longer than the length from one end of the neck strap 61A to the movement restricting portion 75A of the neck strap central portion 61AK along the neck strap one end 61AM. The length of the left speaker cable 66B is selected to be longer than the length from the other end of the neck strap 61A to the movement restricting portion 75B of the neck strap central portion 61AK along the neck strap other end 61AN. . Thus, the right speaker cable 66A and the left speaker cable 66B move until the casings 62 and 64 of the right speaker portion 63 and the left speaker portion 65 are abutted against the movement restricting portions 75A and 75B along the neck strap 61A. Even so, it is slightly slackened, and thus it is avoided that the conductive wire or the film is pulled and a load is applied to cause a breakage.

  As shown in FIG. 24, a circular fitting hole 61BA is provided at the other end of the neck strap fixing portion 61B. A pair of arc-shaped engagement protrusions 61BE and 61BF are provided on the inner wall 61BB of the fitting hole 61BA slightly closer to the opening 61BD than the bottom surface 61BC with the inner surfaces facing each other.
