As shown in FIG. 8A, in a state where the moving unit 310 is stationary before the moving unit 310 starts moving in the forward direction, the urging member 266 causes the connecting member 382 to be attached in the arrow h direction. The moving portion 310 is urged in the direction of the arrow b in the rotational direction by the urging member 266. In this state, the suppression unit 340 is stationary and is in contact with the sound generation valve 212. In addition, the suppression unit 340 is urged by the suppression unit urging member 370 and is pressed against the sound generation valve 212.

  When a current is supplied to the solenoid 260 from the state shown in FIG. 8A, the plunger portion 262 (see FIG. 7) starts to move in the direction of the arrow g, and as shown in FIG. Starts moving in the direction of arrow g, and the moving member 320 starts rotating in the direction of arrow a. The suppression unit 340 is urged by the suppression unit urging member 370 to rotate in the direction of the arrow f until the rotation unit 310 rotates to a predetermined position after the movement unit 310 starts rotating. It is in a state of being pressed against 212.

  When the moving unit 310 further rotates in the direction of arrow a from the position shown in FIG. 8B, the suppressing unit 340 is pressed against the wall surface 322 of the moving member 320 as shown in FIG. The movement is started so as to rotate integrally with the moving member 320 in the direction of arrow a. In other words, in a state where the suppression unit 340 is separated from the sound generation valve 212, the suppression unit 340 is urged by the suppression unit urging member 370 and pressed against the wall surface 322 of the moving member 320. Then, when the suppression unit 340 moves in the direction of arrow a, the suppression unit 340 is separated from the sound generation valve 212. In this way, the suppressing unit 340 is separated from the sound generation valve 212 in conjunction with the forward movement of the moving member 320 indicated by the arrow a.

  Further, when the moving member 320 further moves in the direction of the arrow a, the contact member 330 that is a part of the moving unit 310 comes into contact with the lower surface of the sound generating valve 212 so as to push up the sound generating valve 212. The sound generating valve 212 is vibrated by being separated from the sound 212, and the sound generating valve 212 generates sound.

  FIG. 8D shows a state in which the movement of the moving member 320 in the positive direction indicated by the arrow a has been completed. This state is a state in which the suppressing unit 340 is separated from the sound generation valve 212 and then the contact member 330 vibrates the sound generation valve 212 to generate sound, and the contact member 330 is positioned above the sound generation valve 212.

  FIG. 9 illustrates an operation in which the moving unit 310 moves so as to rotate in the arrow b direction which is the reverse direction. The state shown in FIG. 9 (e) is a state before the moving unit 310 starts moving in the arrow b direction, and the moving unit 310 has finished moving in the arrow a direction. This is the state shown in (d). When the supply of current to the solenoid 260 is stopped from this state, the plunger portion 262 (see FIG. 7) and the connecting member 382 are moved to the arrow by being urged by the urging member 266 (see FIG. 7). The movement in the h direction is started, and in conjunction with this movement, as shown in FIG. 9E, the moving member 320, the suppressing portion 340, and the contact member 330 integrally start to rotate in the arrow b direction. To do.

  Then, when the suppressing unit 340 rotates in the direction of the arrow b integrally with the moving unit 310, the suppressing unit 340 comes into contact with the sound generation valve 212 as shown in FIG. As a result, the suppression unit 340 is pressed against the sound generation valve 212. When the suppression unit 340 comes into contact with and the suppression unit 340 is pressed, vibration of the sound generation valve 212 is suppressed and sound generation due to vibration of the sound generation valve 212 is suppressed.

  Thus, the suppression unit 340 contacts the sound generation valve 212 in conjunction with the movement of the movement unit 310 and suppresses vibration of the sound generation valve 212. More specifically, the suppression unit 340 contacts the sound generation valve 212 in conjunction with the reverse movement indicated by the arrow b of the movement unit 310 to suppress the movement of the sound generation valve 212.

  Here, for example, by adjusting the strength of the biasing member 370 for the restraining portion or the strength of the biasing member 266 of the biasing member 266 (FIG. 7) of the solenoid 260, the restraining portion 340 comes into contact. It is desirable that the sound generation valve 212 does not vibrate and the sound generation valve 212 does not generate sound by pressing the suppression unit 340. Furthermore, it is desirable that the vibration and sound generation of the sound generation valve 212 stop when the suppression portion 340 comes into contact with the sound generation valve 212 that vibrates and generates sound, and the suppression portion 340 is pressed.

  When the moving member 320 further moves in the direction indicated by the arrow b, the contact member 330 that rotates together with the moving member 320 in the arrow b direction contacts the sound generation valve 212 as shown in FIG. At this time, since the suppression unit 340 is pressed against the sound generation valve 212, the vibration of the sound generation valve 212 is suppressed even when the contact member 330 comes into contact, and the sound generation of the sound generation valve 212 due to the vibration is suppressed.

  When the moving member 320 further moves in the direction indicated by the arrow b from the state shown in FIG. 9 (f), the contact member 330 is pushed by the sound generating valve 212 and moves away from the sound generating valve 212. To do. That is, when the contact member 330 is pushed by the sound generation valve 212, the contact member 330 moves in the direction away from the sound generation valve 212 so as to rotate in the direction of the arrow c against the force of the contact member biasing member 360.

  When the moving member 320 further moves in the direction indicated by the arrow b, the contact member 330 passes through the position where it contacts the sound generation valve 212 from above to below, and as shown in FIG. 9G, the sound generation valve. In a state of being separated from 212 and positioned below the sound generation valve 212. In this state, the contact member 330 is urged by the contact member urging member 360 to rotate in the direction of the arrow d, thereby being pressed against the wall surface 322 of the moving member 320. It moves in the direction shown by the arrow b as a unit with 320.

  FIG. 9H shows a state in which the movement of the moving member 320 in the reverse direction indicated by the arrow b has been completed. This state is a state before the moving member 320 starts moving in the positive direction indicated by the arrow a, and is the state shown in FIG.

  FIG. 9 shows a control program 500 that realizes the control method of the music box apparatus 100 according to the embodiment of the present invention. As illustrated in FIG. 9, the control program 500 includes a drive signal control unit 502, a data reception unit 504, a data storage unit 506, a drive signal output unit 508, a timer 510, and a duration determination unit 512.

  In the control program 500, the data reception unit 504 receives performance information input to the control circuit 112 and stores it in the data storage unit 506. For example, when performance information is input via the MIDI-IF 132, the data reception unit 504 stores the performance information in the data storage unit 506 by interrupt processing.

  The data storage unit 506 stores performance information received by the data receiving unit 504. The data storage unit 506 is realized by a storage area taken in the memory 114. The data storage unit 506 is, for example, a ring buffer.

  The drive signal control unit 502 reads the performance information stored in the data storage unit 506 and converts the performance information into a drive signal. Specifically, the drive signal control unit 502 controls the drive signal corresponding to the scale to be an ON signal based on the information about the scale included in the performance information. In this way, the drive signal control unit 502 controls the performance information received by the data receiving unit 504 to be converted into a drive signal. In addition, the drive signal control unit 502 starts timing of a timer 510 described later at a timing when the drive signal is turned on.

  The drive signal output unit 508 outputs a drive signal converted from the performance information to the FET switch 118 under the control of the drive signal control unit 502. For example, the drive signal output unit 508 outputs an ON signal to the FET switching circuit corresponding to the scale included in the FET switch 118. The timer 510 starts measuring time at a timing controlled by the drive signal control unit 502.

  The duration determination unit 512 determines whether or not the value measured by the timer 510 exceeds a predetermined threshold value T1, and if the measured value exceeds the threshold value T1, the drive signal control unit It outputs to 502. The threshold value T1 is a value at which the state where the drive signal is an ON signal can be continued.

  Next, the control process by the control program 500 will be described in more detail. FIG. 11 is a flowchart showing a control process S10 when the drive signal by the control program 500 is turned on.

  As shown in FIG. 11, in step S <b> 100, the drive signal control unit 502 determines whether or not the performance information is to be played on the music box device 100. For example, the drive signal control unit 502 determines whether or not a MIDI data reception channel matches a preset reception channel of the music box apparatus 100. The drive signal control unit 502 proceeds to the process of step S102 if the performance information is to be played on the music box apparatus 100, and ends the control process otherwise.

  In step S102, the drive signal control unit 502 determines whether or not the performance information is information for making a sound. For example, the drive signal control unit 502 determines whether or not the MIDI data event is “note on”. The drive signal control unit 502 proceeds to the process of step S104 if the performance information is information for sounding, and ends the control process otherwise.

  In step S <b> 104, the drive signal control unit 502 determines whether or not the sound being played can be generated by the music box device 100. For example, the drive signal control unit 502 determines whether or not the scale data is included in a range that can be generated by the music box device 100. The drive signal control unit 502 proceeds to the process of step S106 when the sound to be played can be generated by the music box device 100, and ends the control process otherwise.

  In step S106, the drive signal control unit 502 determines whether or not the drive signal corresponding to the musical scale is already an ON signal. The drive signal control unit 502 proceeds to the process of step S108 when the drive signal corresponding to the scale is already on, and proceeds to the process of step S110 when the drive signal corresponding to the scale is off.

  In step S108, the drive signal control unit 502 increases the threshold value T1. That is, the drive signal control unit 502 performs control so that the state in which the drive signal is the on signal continues for a longer time.

  In step S110, the drive signal control unit 502 controls the drive signal output unit 508 so that the drive signal corresponding to the musical scale is an ON signal. The drive signal output unit 508 converts the drive signal corresponding to the scale output to the FET switch 118 into an ON signal.

  When the drive signal is converted to ON, a current flows through the solenoid 260, whereby the contact member 330 of the moving unit 310 contacts the sound generation valve 212, the sound generation valve 212 vibrates, and the sound generation valve 212 emits sound ( (See FIG. 8).

  In step S112, the drive signal control unit 502 controls the timer 510 to start measuring time. The timer 510 starts measuring the time that has elapsed since the drive signal corresponding to this scale was turned on.

  FIG. 12 is a flowchart showing the control process S20 when the drive signal by the control program 500 is converted to OFF. As shown in FIG. 12, in step S200, the drive signal control unit 502 determines whether or not the state in which the drive signal is an on signal continues for the time T1. More specifically, the drive signal control unit 502 determines whether or not a signal indicating that the state in which the drive signal is the ON signal has exceeded the T1 time has been received from the duration determination unit 512. The drive signal control unit 502 proceeds to the process of S202 when the state where the drive signal is the ON signal continues for the time T1, and ends the control process otherwise. The drive signal control unit 502 performs this determination process for drive signals corresponding to all scales.

  In step S202, the drive signal control unit 502 controls the drive signal output unit 508 so that the drive signal corresponding to the scale becomes an off signal. The drive signal output unit 508 converts the drive signal corresponding to the scale output to the FET switch 118 into an off signal. As a result, the supply of current to the solenoid 260 corresponding to this scale is stopped.

  FIG. 12 is a flowchart showing the overall operation S30 of the music box apparatus 100 according to the embodiment of the present invention. When the user presses the white key or black key on the keyboard 20, performance information is output from the keyboard 20 to the music box device 100. When the performance information is input to the music box device 100 and received by the data receiving unit 504 of the control program 500, the performance information is stored in the data storage unit 506, for example, by interrupt processing. The performance information may be transmitted from the terminal device 22 or acquired from the external recording device 24 or the server device 26.

  As shown in FIG. 12, in step S300, the drive signal control unit 502 of the control program 500 determines whether or not the accepted performance information is stored in the data storage unit 506. When the performance information is stored in the data storage unit 506, the drive signal control unit 502 proceeds to the process of step S302. On the other hand, if the performance information is not stored in the data storage unit 506, the control program 500 proceeds to step S20, which is a control process for converting the drive signal to OFF.

In step S302, the drive signal control unit 502 reads performance information stored in the data storage unit 506. Thereafter, the control program 500 executes a control process S10 for converting the drive signal to ON.

  Further, the control program 500 executes a control process S20 when converting the drive signal to OFF. In this way, the music box device 100 receives the performance information and emits a sound based on the performance information.

  As described above, the present invention can be applied to a music box device and a music box system.
