FIG. 1 is a diagram showing a music box system 1 including a music box device 10 according to an embodiment of the present invention.
As shown in FIG. 1, the music box system 1 is connected to the music box device 10 through a music box device 10, a keyboard 12 and a terminal device 14 connected to the music box device 10, an external recording device 16, and a network 20. And a server device 18.

  The music box device 10 performs by receiving performance information from the keyboard 12 or the terminal device 14 and converting the performance information into a drive signal. Further, the music box device 10 reads performance information from the external recording device 16 or acquires performance information from the server device 18. The music box device 10 will be described in detail later.

  The keyboard 12 outputs performance information to the music box device 10. The keyboard 12 has a plurality of white keys and black keys. When a white key or a black key is pressed, the keyboard 12 outputs performance information including information related to the scale corresponding to the pressed white key or black key to the music box device 10. The keyboard 12 is also called a keyboard.

  The terminal device 14 is a general-purpose personal computer, for example, and includes a CPU, a memory, a communication device, a keyboard, a mouse, and the like (not shown). The terminal device 14 stores performance information. The terminal device 14 outputs the stored performance information to the music box device 10. Further, the terminal device 14 may output performance information including information related to the scale designated by the keyboard or the mouse to the music box device 10.

  The external recording device 16 is, for example, a CD, a DVD, a card type recording device, or the like. Performance information is recorded in the external recording device 16. When the external recording device 16 is attached to the music box device 10, the stored performance information can be read from the music box device 10.

  The network 20 is a network configured by, for example, a LAN, a WAN, or the like. The network 20 may be a wired network or a wireless network.

  The server device 18 is a web server, for example, and has a configuration equivalent to that of the terminal device 14. The server device 18 stores performance information. Upon receiving a download request from the music box device 10, the server device 18 transmits the stored performance information to the music box device 10.

  The performance information is, for example, MIDI (Musical Instruments Digital Interface) data. The performance information includes the scale corresponding to the pressed key, the strength at which the key is pressed, the timing at which the key was pressed, and the like.

FIG. 2 is a diagram showing a configuration of the music box device 10 according to the embodiment of the present invention.
As shown in FIG. 2, the music box device 10 includes a control unit 22, a music box unit 24, an AC adapter, and a display device 28. The control unit 22 includes a CPU 30, a memory 32, a clock device 34, a FET (Field Effect Transistor) switch 36, a power switch 38, an amplifier device 40, a MIDI-interface (IF) 42, an external recording device IF 44 and a communication IF 46. . The music box unit 24 includes a motor 48, a drive unit 50, a claw mechanism 52, and a diaphragm 54.

  In the control unit 22, the CPU 30 executes a later-described control program 100 stored in the memory 32. Further, the CPU 30 inputs and outputs signals to and from other components included in the control unit 22.

  The clock device 34 outputs a signal to the CPU 30 at the set time based on the time set by the operator, and controls the CPU 30 to operate at a desired time.

  The FET switch 36 controls a current flowing in the drive unit 50 described later based on a drive signal output from the CPU 30. More specifically, when the FET switch 36 receives an ON signal (also referred to as a high signal) from the CPU 30, the FET switch 36 controls the current to flow through the driving unit 46 and receives an OFF signal (also referred to as a low signal) from the CPU 30. In such a case, control is performed so that no current flows through the drive unit 50.

  The FET switch 36 includes n FET switching circuits (not shown). Here, n is the number of vibration valves 56 described later, for example, n = 33. Therefore, the FET switch 36 controls the current flowing through the drive unit 50 so that the vibration valve 56 corresponding to the FET switching circuit is repelled based on the drive signal for each FET switching circuit.

  When the power switch 38 is in an ON state, the power switch 38 supplies a predetermined voltage supplied from the AC adapter 26 to other components included in the control unit 22 and components included in the music box unit 24 described later. To do.

  The MIDI-IF 42 receives performance information output from the keyboard 12 or the terminal device 14 and outputs it to the CPU 30. The external recording device IF 44 outputs the performance information read from the external recording device 16 to the CPU 30. The communication IF 46 receives performance information transmitted from the server device 18 via the network 20 and outputs the performance information to the CPU 30.

  The amplifier device 40 receives an output signal from a pickup 58 that is disposed below the diaphragm 54 and converts resonance sound into an electrical signal, and amplifies this signal. Further, a line-out terminal 60 for taking out a signal is connected to the amplifier device.

  In the music box unit 24, the motor 48 is driven so that a claw mechanism 52 described later rotates. The vibration plate 54 includes a plurality of vibration valves 56-1 to 56-n formed in a comb shape. The lengths of the vibration valves 56-1 to 56-n are different from each other, and when the vibration valves 56-1 to 56-n are played, the sound of the corresponding scale is emitted.

  The drive unit 50 drives a claw mechanism 52 described later based on the drive signal. More specifically, the drive unit 50 transmits the driving force of the motor 48 to the claw mechanism 52 when a current flows through the FET switch 36, and the claw mechanism 52 of the motor 48 when the current is interrupted by the FET switch 36. The driving force against is cut off.

  When the claw mechanism 52 is driven by the drive unit 50, the claw mechanism 52 is rotated by the motor 48 and repels at least one of the vibration valves 56-1 to 56-n included in the diaphragm. The display device 28 is, for example, a liquid crystal display or LED (Light Emitting Diode), and displays a musical score corresponding to performance information, a performance status, and the like. FIG. 3 is a diagram illustrating a detailed configuration of the driving unit 50 and the claw mechanism 52.

FIG. 3 is a diagram illustrating a detailed configuration of the driving unit 50 and the claw mechanism 52.
As shown in FIG. 3, the drive unit 50 includes a solenoid 62 and a stop member 64. The solenoid 62 has a moving member 66 and moves the moving member 66 in the longitudinal direction of the solenoid 62. The drive unit 50 is provided with n combinations of such solenoids 62 and stop members 64. This combination corresponds to each FET switching circuit included in the FET switch 36. When a current is passed through the solenoid 62 by the FET switching circuit, the drive unit 50 moves the stop member 64 in the direction of the arrow B in the drawing to control the claw wheel 72 described later to rotate. The drive unit 50 may include, for example, n actuators instead of the solenoid 62.

  The stop member 64 has a shaft 68 and a locking portion 70 provided at one end of the stop member 64. The stop member 64 is provided to be rotatable about a shaft 68. The locking portion 70 is provided so as to abut on a claw wheel 72 and a rotation control member 86 of the claw mechanism 52 described later. The other end of the stop member 64 is engaged with the moving member 66 of the solenoid 62. When the moving member 66 is moved in the direction of arrow B in the figure, the stop member 64 rotates about the shaft 68, and the locking portion 70 moves to a position away from the claw wheel 72 and the rotation control member 86. .

  The claw mechanism 52 includes n claw wheels 72, a drive shaft 80 fitted in the claw wheel 72, a rotation shaft 78 fitted in the drive shaft 80, a rotation control member 86, and a clutch member 84. On the outer periphery of the claw wheel 72, a plurality of (for example, six) claw portions 74 are provided at the same angle. A protrusion 76 is provided at the rear end of the claw portion 74 in the rotational direction (the direction of arrow A). Further, the hook wheel 72 is provided with, for example, three deformed holes 82. The deformed hole 82 is formed so that the radius decreases in accordance with the rotation direction A.

  The rotation control member 86 is fitted into the drive shaft 80 so as to be frictionally engaged with the claw wheel 72. The clutch member 84 is provided between the rotation control member 86 and the claw wheel 72 so as to be fitted into the deformed hole 82 of the claw wheel 72.

  Accordingly, when the locking portion 70 is in contact with the claw wheel 72 and the rotation control member 86, the rotation of the claw wheel 72 and the rotation control member is prevented. On the other hand, when the locking portion 70 is moved to a position away from the claw wheel 72 and the rotation control member, the claw wheel 72 and the rotation control member 86 rotate in the direction of the arrow A. When the rotation control member 86 rotates, the clutch member 84 moves in a direction in which the radius of the deformed hole 82 decreases. Thereby, the ratchet wheel 72 and the rotation control member 86 are rotated together. Therefore, the vibration valve 56 corresponding to the claw wheel 72 is bounced by the protrusion 76 of the claw wheel 72.

  4 to 6 show a case in which a swing electromagnetic actuator 88 is used instead of the solenoid 62 as another embodiment. FIG. 4 schematically shows the drive unit 50 and the rotation control member 84. In FIG. 5, only three units of the driving unit 50 and the claw mechanism 52 are illustrated, and n units are provided. In FIG. 6, only one unit of the drive unit 50 and the claw mechanism 52 is shown, and n units are provided. The oscillating electromagnetic actuator 88 is sandwiched between support portions 90 provided in the music box unit 24, and is disposed so as to be stacked substantially on the same axis.

  The swing electromagnetic actuator 88 has a fixed portion 92 a, a fixed portion 92 b including an electromagnet 94, and a swing portion 98 including a permanent magnet 96. The swinging part 98 is disposed so as to be rotatable about a swinging shaft 99 attached to the fixing part 92b so as to be sandwiched between the fixing part 92a and the fixing part 92b, and the other end of the swinging part 98 is the stop member 64. Is engaged.

  The electromagnet 94 is divided into magnetic poles on the side facing the permanent magnet 96 and on the opposite side thereof, and the side facing the permanent magnet 96 and the magnetic pole on the opposite side are controlled according to the direction of the current passed through the electromagnet. . The permanent magnet 96 is provided so that the magnetic poles are separated with respect to the rotation direction, and is disposed at a position where the center of the electromagnet 94 and the center of the permanent magnet 96 do not overlap. The operation of the drive unit 50 corresponds to each FET switching circuit included in the FET switch 36. When a current is passed through the electromagnet 94 by the FET switching circuit, the drive unit 50 moves the swinging unit 98 and controls the claw wheel 72 to rotate.

Control of rotation of the ratchet wheel 72 by the swing electromagnetic actuator 88 will be described. For example, the permanent magnet 96 is arranged such that the upper side is the north pole and the lower side is the south pole, and the center thereof is located above the center of the electromagnet 94 with respect to the rotational direction. When the electromagnet 94 is not energized, the swinging portion 98 is disposed at a position where the locking portion 70 of the stop member 64 comes into contact with the hook wheel 72 and the rotation control member 86 (FIG. 4A).
When the side of the electromagnet 94 facing the permanent magnet 96 is controlled to be N-pole, the permanent magnet 96 is repelled upward with respect to the rotation direction, so that the swinging portion 98 is moved in the clockwise direction and swings. The stop member 64 engaged with the portion 98 is moved to a position away from the rotation control member 86 side (FIG. 4B).
It is also possible to bias the stop member 64 by a spring or the like in the direction of moving the stop member 64 to the position on the rotation control member 86 side.

  Structurally, the oscillating electromagnetic actuator 88 is thinner in the width direction (stacking direction) than the solenoid 62, and the pitch is narrowed to the same extent as the vibration valve 56.

FIG. 7 is a control program 100 that realizes a control method of the music box apparatus 10 according to the embodiment of the present invention.
As shown in FIG. 7, the control program 100 includes a drive signal control unit 102, a data reception unit 104, a data storage unit 106, a drive signal output unit 108, a timer 110, and a duration determination unit 112.

  In the control program 100, the data reception unit 104 receives performance information input to the CPU 30 and stores it in the data storage unit 106. For example, when performance information is input via the MIDI-IF 38, the data reception unit 104 stores the performance information in the data storage unit 106 by interrupt processing.

  The data storage unit 106 stores performance information received by the data receiving unit 104. The data storage unit 106 is realized by a storage area taken in the memory 32. The data storage unit 106 is, for example, a ring buffer.

  The drive signal control unit 102 reads performance information stored in the data storage unit 106 and converts this performance information into a drive signal. Specifically, the drive signal control unit 102 performs control so that the drive signal corresponding to the scale becomes an ON signal based on the information regarding the scale included in the performance information. In this way, the drive signal control unit 102 performs control so that the performance information received by the data receiving unit 104 is converted into a drive signal. Further, the drive signal control unit 102 starts timing of a timer 110 described later at a timing when the drive signal is turned on.

The drive signal output unit 108 outputs a drive signal converted from performance information to the FET switch 36 under the control of the drive signal control unit 102. For example, the drive signal output unit 108 outputs an ON signal to the FET switching circuit corresponding to the scale included in the FET switch 36.
The timer 110 starts measuring time at a timing controlled by the drive signal control unit 102.

  The duration determination unit 112 determines whether or not the value measured by the timer 110 exceeds a predetermined threshold value T1, and if the measured value exceeds the threshold value T1, the drive signal control unit 102 for output. The threshold value T1 is a value at which the state where the drive signal is an ON signal can be continued. For example, the threshold value T <b> 1 is a value smaller than the time from when the projection 76 of the claw wheel 72 bounces the vibration valve 56 to when the next projection 76 of the claw wheel 72 bounces the vibration valve 56.

Next, control processing by the control program 100 will be described in more detail.
FIG. 8 shows a flowchart of the control process (S10) when the drive signal by the control program 100 is turned on.
As shown in FIG. 8, in step 100 (S100), the drive signal control unit 102 determines whether or not the performance information is to be played in the music box device 10. For example, the drive signal control unit 102 determines whether or not a MIDI data reception channel matches a preset reception channel of the music box device 10. The drive signal control unit 102 proceeds to the process of S102 if the performance information is to be played on the music box device 10, and ends the control process otherwise.

  In step 102 (S102), the drive signal control unit 102 determines whether or not the performance information is information for making a sound. For example, the drive signal control unit 102 determines whether or not the MIDI data event is “note on”. The drive signal control unit 102 proceeds to the process of S104 when the performance information is information for sounding, and ends the control process otherwise.

  In step 104 (S104), the drive signal control unit 102 determines whether or not the sound to be played can be generated by the music box device 10. For example, the drive signal control unit 102 determines whether or not the scale data is included in a range that can be generated by the music box device 10. The drive signal control unit 102 proceeds to the process of S106 when the sound to be played can be generated by the music box apparatus 10, and ends the control process otherwise.

  In step 106 (S106), the drive signal control unit 102 determines whether or not the drive signal corresponding to the scale is already an ON signal. The drive signal control unit 102 proceeds to the process of S108 when the drive signal corresponding to the scale is already on, and proceeds to the process of S110 when the drive signal corresponding to the scale is off.

  In step 108 (S108), the drive signal control unit 102 increases the threshold value T1. That is, the drive signal control unit 102 performs control so that the state in which the drive signal is an on signal continues for a longer time. For example, the drive signal control unit 102 adds a sufficient time for the protrusion 76 of the claw wheel 72 to flip the vibration valve 56 once to the threshold value T1. Accordingly, since the time for which the claw wheel 72 rotates is extended, the protrusion 76 of the claw wheel 72 flips the vibration valve 56.

  In step 110 (S110), the drive signal control unit 102 controls the drive signal output unit 108 so that the drive signal corresponding to the scale becomes an ON signal. The drive signal output unit 108 converts the drive signal output to the FET switch 36 and corresponding to this musical scale into an ON signal.

  When the drive signal is converted to ON, a current flows to the drive unit 46, and the drive unit 46 drives the claw mechanism 52. When the claw mechanism 52 is driven by the drive unit 46, the claw wheel 72 is rotated by the driving force of the motor 48, and the projection 76 of the claw wheel 72 is a scale vibration valve corresponding to the drive signal converted to ON. Play 56.

  In step 112 (S112), the drive signal control unit 102 controls the timer 110 to start timing. The timer 110 starts measuring the time that has elapsed since the drive signal corresponding to this scale was turned on.

FIG. 9 shows a flowchart of the control process (S20) when the drive signal by the control program 100 is converted to OFF.
As shown in FIG. 9, in step 200 (S200), the drive signal control unit 102 determines whether or not the state in which the drive signal is an on signal continues for a time T1. More specifically, the drive signal control unit 102 determines whether or not a signal indicating that the state in which the drive signal is an ON signal has exceeded the T1 time has been received from the duration determination unit 112. The drive signal control unit 102 proceeds to the process of S202 when the state in which the drive signal is the on signal continues for the time T1, and ends the control process otherwise. The drive signal control unit 102 performs this determination process on the drive signals corresponding to all the scales.

  In step 202 (S202), the drive signal control unit 102 controls the drive signal output unit 108 so that the drive signal corresponding to the scale becomes an off signal. The drive signal output unit 108 converts the drive signal output to the FET switch 36 and corresponding to this musical scale into an off signal. Therefore, the rotation of the ratchet wheel 72 corresponding to this scale is stopped.

FIG. 10 shows a flowchart of the overall operation (S30) of the music box apparatus 10 according to the embodiment of the present invention.
When the user presses the white key or black key on the keyboard 12, performance information is output from the keyboard 12 to the music box device 10. When the performance information is input to the music box device 10 and received by the data receiving unit 104 of the control program 100, the performance information is stored in the data storage unit 106 by, for example, interrupt processing. The performance information may be transmitted from the terminal device 14 or acquired from the external recording device 16 or the server device 18.

  As shown in FIG. 10, in step 300 (S300), the drive signal control unit 102 of the control program 100 determines whether or not the received performance information is stored in the data storage unit 106. When the performance information is stored in the data storage unit 106, the drive signal control unit 102 proceeds to the process of S302. On the other hand, when the performance information is not stored in the data storage unit 106, the control program 100 proceeds to a control process (S20) for converting the drive signal to OFF.

  In step 302 (S302), the drive signal control unit 102 reads performance information stored in the data storage unit 106. Thereafter, the control program 100 executes a control process (S10) for converting the drive signal to ON.

  In addition, the control program 100 executes a control process (S20) when the drive signal is converted to OFF. In this way, the music box device 10 receives performance information and emits a sound based on the performance information.
