  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1A is a diagram showing a configuration of a musical tone control signal communication system including a musical tone control signal generating device according to an embodiment of the present invention. FIG. 1B is a perspective view of the musical tone control signal generator, and FIG. 2 is an internal perspective view of the musical tone control signal generator in a longitudinal section. A performance operating device (hereinafter referred to as a pedal device 10) exemplified as the musical tone control signal generating device is configured as a foot pedal as an example. The pedal device 10 shown in FIGS. 1A and 1B is shown with the cover 13 removed. The musical tone control signal communication system includes a pedal device 10, a receiving module 50, and a musical instrument 40. The musical instrument 40 is an example of a musical sound generator. An electronic keyboard musical instrument is exemplified as the musical instrument 40, but the electronic musical instrument is not particularly limited, and may be another electronic musical instrument such as a guitar.

  Hereinafter, as will be described in detail, the pedal device 10 wirelessly transmits a tone control signal to the reception module 50. The receiving module 50 is connected to the input terminal 41 of the musical instrument 40, and a musical tone control signal is transmitted from the pedal device 10 to the receiving module 50. The musical tone control signal is reflected in the musical tone control in the musical instrument 40. In the present embodiment, a configuration in which the pedal device 10 is used as a sustain pedal for adding a sustain effect to a musical sound generated by the musical instrument 40 is illustrated. The pedal device 10 acquires a musical tone control signal by playing and transmits it to the receiving module 50. The pedal device 10 can acquire and transmit a signal using the power generated by the performance operation without receiving power supply from the outside.

  The pedal device 10 has a pedal portion 12 disposed on a base portion 11 so as to be rotatable about a rotation fulcrum P1 (FIG. 2). A half portion of the pedal portion 12 on the rotation fulcrum P1 side and components in the vicinity thereof are covered with a cover 13. The free end portion of the pedal portion 12 is always urged upward by a spring 19 (FIG. 1A). As a performance operation, the player can perform a pressing operation of stepping on the free end portion of the pedal portion 12 with a foot and a releasing operation of releasing the foot. The initial position (rest position) of the pedal portion 12 in the non-operating state is defined by the upper stopper 14, and the rotation end position (end position) of the pedal portion 12 in the forward stroke of the performance operation is defined by the lower stopper 15. The upper stopper 14 and the lower stopper 15 are provided with a cushioning material or an elastic material that comes into contact with the pedal portion 12.

  The attachment portion 9 is fixed with a screw at a position near the pivot point P1 of the pedal portion 12 (FIG. 1 (a)). The attachment portion 9 has a switch drive portion 17. In addition, a detection unit 18 is disposed on the base unit 11 at a position corresponding to the switch driving unit 17. The detection unit 18 includes a contact type switch 18a. As the switch 18a, for example, a leaf switch is adopted, and the switch 18a is disposed so as to be pressed downward by the switch driving unit 17 (see also FIG. 5). The switch 18a is turned on and off at a predetermined position (detected position ST1 in FIG. 3A) in the operation stroke in the performance. Turns off after passing position.

  As shown in FIG. 2, the power generation mechanism portion 20 is disposed on the base portion 11 in the cover 13 closer to the free end portion of the pedal portion 12 than the rotation fulcrum P1. The power generation mechanism unit 20 includes a driven piece 21, a transmission small gear 22, a transmission large gear 23, a driven gear 24, and a rotary generator 25. The driven piece 21 is rotatable about a rotation fulcrum P2. The driven piece 21 is formed with an engaging portion having a claw shape at the forward engagement portion 21a and the return engagement portion 21b, and a drive gear portion is provided on the opposite side of the engagement portion with the rotation fulcrum P2 interposed therebetween. 21c is formed. A drive pin 16 fixedly provided on the pedal portion 12 is engaged with a recess formed by the forward engagement portion 21a and the reverse engagement portion 21b. When the pedal portion 12 is rotated in the forward / reverse direction, the forward engagement portion 21a / reverse engagement portion 21b is driven, and the driven piece 21 is rotated.

  The transmission small gear 22 and the transmission large gear 23 are in a fixed relationship, and can rotate integrally around a common rotation fulcrum P3. The drive gear portion 21 c of the driven piece 21 meshes with the transmission small gear 22, and the rotation of the driven piece 21 is transmitted to the transmission large gear 23 via the transmission small gear 22. The generator 25 has the same configuration as the motor, and the driven gear 24 is fixed to the end of the shaft portion. The shaft portion of the generator 25 and the driven gear 24 are rotatable around a common rotation fulcrum P4. The transmission large gear 23 meshes with the driven gear 24, and the rotation of the transmission large gear 23 is transmitted to the shaft portion of the generator 25 via the driven gear 24, and the generator 25 generates power.

  The rotation direction of each gear is referred to as the direction in FIG. 2 to illustrate the operation. When the player steps on the pedal portion 12, the drive pin 16 drives the forward engagement portion 21a, whereby the driven piece 21 rotates clockwise, and the drive gear portion 21c drives the transmission small gear 22 for transmission. The small gear 22 and the transmission large gear 23 rotate counterclockwise. The transmission large gear 23 drives the driven gear 24 so that the driven gear 24 rotates clockwise. Thereby, in the operation forward stroke, the shaft portion of the generator 25 is rotated clockwise to generate power.

  When the player removes his / her foot from the pedal portion 12, the pedal portion 12 is rotated in the backward direction by the force of the spring 19 (FIG. 1B). At that time, when the drive pin 16 drives the return side engaging portion 21b, the driven piece 21 rotates counterclockwise, the drive gear portion 21c drives the transmission small gear 22, and the transmission small gear 22 and transmission The large gear 23 rotates clockwise. The transmission large gear 23 drives the driven gear 24, and the driven gear 24 rotates counterclockwise. Thereby, the rotation direction is opposite to that of the operation forward stroke, but in the operation reverse stroke, the shaft portion of the generator 25 is rotated counterclockwise to generate power. Thus, the generator 25 generates power in conjunction with the operation in both strokes of the operation. In addition, sufficient power can be obtained by normal operation of the pedal portion 12 due to the recent improvement in performance of the magnet.

  FIG. 3A is a conceptual diagram showing the relationship among the performance operation stroke of the pedal unit 12, the power generation possible period, and the operation detection position. As described above, the performance operation stroke (stroke between the rest position and the end position) of the pedal unit 12 is defined by the upper stopper 14 and the lower stopper 15. That is, the rest position is defined by contact with the upper stopper 14 of the pedal portion 12, and the end position is defined by contact with the lower stopper 15.

  In the performance operation stroke, a power generation possible section is considered as a section in which the generator 25 can operate appropriately and perform stable power generation. In the vicinity of the rest position, the pedal portion 12 usually has a “play” of movement. Further, in the vicinity of the rest position and the end position, when the pedal portion 12 comes into contact with the cushioning material provided in the upper stopper 14 and the lower stopper 15, the sinking of the cushioning material occurs. The rotation speed becomes slow. Therefore, the power generation possible section is a section from a position slightly deeper than the rest position to a position slightly shallower than the end position in consideration of a margin. On the other hand, the switch 18a is arranged so that the detection position ST1 where the position of the pedal portion 12 by the switch 18a is detected is within the range of the power generation possible section.

  FIG. 3B is a diagram showing an electrical configuration for realizing power generation means, acquisition means for acquiring a musical sound control signal, and output means for outputting the musical sound control signal wirelessly. A voltage stabilization unit 26 is connected to the generator 25, a sensor signal wireless carrier unit 30 is connected to the voltage stabilization unit 26, and a detection unit 18 is connected to the sensor signal wireless carrier unit 30. The voltage stabilizing unit 26 includes a bridge-type full-wave rectifier circuit 27, a stabilized power supply unit 28, and a smoothing capacitor 29. The full-wave rectifier circuit 27 is configured by combining four diodes. The full-wave rectification circuit 27 performs full-wave rectification on the AC signal from the generator 25 side and outputs it to the stabilized power supply unit 28 side. The stabilized power supply unit 28 is configured by, for example, a DC / DC converter. The voltage stabilizing unit 26 provides a direct current output to the sensor signal wireless carrier unit 30. The sensor signal wireless carrier unit 30 can wirelessly transmit a signal from an antenna (ANT).

  In the present embodiment, “Bluetooth Low Energy (BLE) (registered trademark)”, which is a short-range wireless standard, is adopted as a communication standard for wirelessly transmitting a tone control signal. “CC2541 (registered trademark)” manufactured by Texas Instruments Co., Ltd. is employed as the sensor signal wireless transfer unit 30. The CC2541 includes a CPU, but the sensor signal wireless transfer unit 30 is realized by rewriting part of the contents of the program memory. CC2541 has a terminal “P1_1 / LED”, and it is recommended that an LED be externally attached to the terminal “P1_1 / LED”. In the present embodiment, the output terminal of the detection unit 18 is assigned to the terminal “P1_1 / LED” to be used as a switch input port, and the program memory is rewritten accordingly. In the BLE modulation method, the frequency is modulated according to 0/1 of the bit data, and a binary number is expressed.

  The terminal C shown in FIG. 3B corresponds to the terminal “P1_1 / LED”. When the pedal portion 12 is not operated, the switch 18a is not conductive, the terminal C has a predetermined voltage value (for example, 5V), and the level is “H”. When the pedal portion 12 is depressed to the detection position ST1 and the switch 18a is turned on, the terminal C is grounded and becomes 0V, and the level becomes “L”. In this way, the sensor state in the detection unit 18 is taken into the sensor signal wireless transfer unit 30 and determined by the CPU.

  In addition, the terminal A in the sensor signal wireless carrier unit 30 corresponds to the terminal Vcc that receives power supply in CC2541. Terminals B and E correspond to the GND terminal in CC2541. Terminal D corresponds to terminals RF_P and RF_N that perform antenna output in CC2541. As described above, when the pedal unit 12 is operated, the generator 25 generates power, and during the power generation possible period, the sensor signal wireless carrier unit 30 detects the on or off state of the detection unit 18 and the detection result. Is acquired as a musical sound control signal, and the musical sound control signal is wirelessly transmitted from the antenna.

  CC2541 is also adopted for the receiving module 50, and the program memory is rewritten and used. In the receiving module 50, the terminal “P1_1 / LED” is used as an output port to the musical sound generator side such as a musical instrument. In order for the receiving module 50 to properly receive the signal transmitted by the sensor signal wireless carrier unit 30, information that associates the two is used. For example, the sensor signal wireless carrier unit 30 adds the ID code “035” to the musical tone control signal and transmits them together. The receiving module 50 sends the received musical tone control signal and ID code to the musical instrument 40.

  FIG. 4 is a diagram illustrating a connection state between the reception module 50 and the musical instrument 40. The reception module 50 includes a sensor signal wireless power reception unit 51 and an output plug 52. An input terminal 41 is provided on the back surface of the musical instrument 40. The input terminal 41 is, for example, an input terminal for a sustain pedal, and may be a terminal for connecting a general wired connection sustain pedal. When the pedal device 10 is used as a wireless sustain pedal, the output plug 52 is inserted into the input terminal 41.

  In the musical instrument 40, the performance information generating unit 47 is, for example, a keyboard operator. The tone signal generator 45 converts the performance data input from the performance information generator 47 into a tone signal. An input signal input via the terminal 43 of the input terminal 41 is supplied to the musical sound generator 46. The musical sound generator 46 generates an acoustic signal based on the musical sound signal input from the musical sound signal generator 45 and the input signal input from the input terminal 41.

  In such a configuration, when the sensor signal wireless power receiving unit 51 receives the musical tone control signal and the ID code transmitted from the sensor signal wireless carrier unit 30 from the antenna, these signals are input to the input terminal 41 via the output plug 52. Are input to the musical tone generator 46 as input signals. In the present embodiment, as an example, the sustain time (length) of the musical sound generated from the musical sound generator 46 is controlled based on the musical sound control signal. Specifically, when a musical sound control signal indicating pedal on is input, the musical sound level generated by pressing the key is naturally attenuated without being muted even when the key is released. However, if a tone control signal indicating pedal off is input during natural decay, the sound is muted. When a musical tone control signal indicating pedal on is not input, the musical tone generated by the key depression is quickly muted when the key is released.

  According to the present embodiment, the generator 25 generates power using the operation of the pedal unit 12 by the performance operation as a power source, and the sensor signal wireless transfer unit 30 detects the operation of the pedal unit 12 using the generated power. The musical sound control signal is acquired, and the musical sound control signal is wirelessly output from the antenna using the generated power. Accordingly, the musical tone control signal can be output wirelessly by a performance operation without requiring power supply by wire and without worrying about running out of power.

  Moreover, it has a power generation possible section within the range of the operation stroke of the pedal section 12, and the detection position ST1 of the operation of the pedal section 12 in the operation stroke is included in the power generation possible section. Therefore, the operation of the pedal unit 12 can be detected during the power generation period, and a charging function is not required. In addition, in each of the pressing operation step and the release operation step, it is possible to acquire a musical sound control signal and wirelessly output a musical sound control signal using the power generated by the operation. Therefore, it is possible to wirelessly output a tone control signal in each step of the pressing operation and the releasing operation without requiring a charging function. There is no power cost. A charging device for storing the generated power may be provided.

  Note that the detection unit 18 only needs to be able to detect the operation of the pedal unit 12, and therefore may not be a contact type, and may be an optical type or a magnetic type. Further, two or more detection positions may be provided instead of one, and the operation speed (velocity) may be detected. FIG. 5 shows a modification.

  For example, as shown in FIGS. 5A and 5B, conductive pieces 31 and 32 that can contact the terminal 33 are provided as upper and lower portions as the detection unit 18. FIG. 5C is a conceptual diagram showing the relationship among the performance operation stroke, the power generation possible period, and the operation detection position of the pedal unit 12 when the detection unit 18 of the modification is employed.

  In the initial state of the pedal portion 12, the terminal 33 is in contact with the upper conductive piece 31 (FIG. 5A). When the pedal portion 12 is pressed down and the stroke position when the terminal 33 moves away from the conductive piece 31 is detected position ST1, and further pressed down, the terminal 33 comes into contact with the lower conductive piece 32 (FIG. 5B). This stroke position is defined as a detection position ST2. In the operation forward stroke, the velocity is grasped by acquiring the time difference from when the ON is detected at the detection position ST1 to when the ON is detected at the detection position ST2. However, the signal to be transmitted by radio may be an on or off signal at the detection position ST1 or an on or off signal at the detection position ST2, and the velocity may be calculated by the instrument 40. In this case, the on / off signal at the detection positions ST1 and ST2 is the tone control signal. Note that the sensor signal wireless carrier unit 30 may be provided with a velocity calculation function so that a signal indicating velocity is included in the musical sound control signal to be transmitted.

  As shown in FIG. 5C, the detection positions ST1, ST2 of the operation of the pedal portion 12 in the operation stroke are both included in the power generation possible section. In the examples shown in FIGS. 5A to 5C, the detection positions coincide with each other in the forward stroke and the backward stroke. However, a switch configuration in which detection is performed at different positions may be employed. Even in such a case, it is desirable that any detection position is included in the power generation possible section.

  Further, as shown in FIG. 5D, another modification may be adopted for the detection unit 18. As the pedal portion 12 is displaced, the contact element moves along the variable resistance, whereby the resistance value continuously changes. When this configuration is adopted, a signal corresponding to the degree of depression of the pedal unit 12 can be acquired. That is, the terminal C can take not only the levels “H” and “L” but also an intermediate value thereof. And a detection signal is taken in into sensor signal wireless conveyance part 30, and the amount of depression is judged by CPU. If the musical tone control signal includes an intermediate value other than on or off, such as the amount of depression, the musical tone control on the musical instrument 40 may be reflected in the volume of the musical tone, for example.

  After all, the tone control signal may be general-purpose, and it can be determined how to use it on the side of the receiving musical instrument, tone generator module, etc. (music tone generator having a tone generator). Therefore, the content of the musical sound control is not limited to the sustain length, but may be an effect such as a resonance sound. In addition, in the case where the velocity information is included in the tone control signal, the effect may be reflected in addition to the volume, such as the depth of the resonance sound.

  Note that any wireless communication standard that can be adopted is not limited to BLE. For example, a communication method or a signal method capable of transmitting to a commercially available receiving module may be adopted. Further, the function of the receiving module 50 may be provided in the musical instrument 40 in advance. Note that, from the viewpoint of increasing the return force in the backward stroke in the operation of the pedal portion 12, the driving force of the pedal portion 12 may be transmitted to the generator 25 only in the forward stroke. For example, a one-way clutch may be provided on at least one of the rotation fulcrums P3 and P4. Thereby, hysteresis can be provided between the forward stroke and the backward stroke, and mechanical noise in the backward stroke can be reduced. Moreover, although what was illustrated was an effect imparting pedal, the operation unit may be a performance operation unit operated by hand. The tone control signal may be a signal for generating a tone, for example, a foot keyboard may be adopted as a performance operating device.

  Next, various modified examples will be described with reference to FIGS. First, a device for receiving a musical tone control signal is not limited to a musical instrument, and may be a musical tone generator having a sound source unit or the like. For example, as shown in FIG. 6A, a MIDI keyboard 60 is provided as a musical sound control signal generator, and a musical sound generator 62 is provided separately from the MIDI keyboard 60 as a device for receiving a musical sound control signal. Each of the keys of the MIDI keyboard 60 is provided with a power generation function and a tone control signal acquisition function. Further, the MIDI keyboard 60 is provided with an output function (output means 73) corresponding to the above-described sensor signal wireless transfer section 30, so that a tone control signal acquired by operating each key is output from the output means 73 wirelessly. To. The musical sound generator 62 includes a receiving module 50 (or a wireless reception I / F), a musical sound signal generator 45, a musical sound generator 46, and a performance information generator 47 (FIG. 4). A MIDI signal generated in accordance with the performance operation and acquired / generated based on the detection signal of the performance operation is wirelessly transmitted, and the tone generator 62 generates a sound based on the received MIDI signal.

  It should be noted that a power generation means (corresponding to the generator 25 in FIG. 3 (b)), an acquisition means for acquiring a musical sound control signal (corresponding to the sensor signal wireless transfer unit 30 and the detection unit 18), and a musical sound control The musical tone control signal generator having an output means (corresponding to the sensor signal wireless carrier 30) for outputting a signal wirelessly may be used by being attached to an existing (commercially available) musical instrument or performance operating device. Therefore, it is not essential that the musical tone control signal generator itself has an operation unit, and power generation may be performed by a performance operation of the operation unit of an attached musical instrument or the like. These examples will be described with reference to FIGS.

  For example, as shown in FIG. 6B, a musical tone control signal generator 70 is disposed and used at a position driven by an operating pedal of a pedal device 63 as a performance operating device. Further, as shown in FIG. 6C, a musical sound control signal generator 70 is disposed on the rotation shaft portion of the beater 65 that is rotationally driven by the pedal device 64 for the electronic bass drum. You may make it generate electric power by dynamic operation. Alternatively, as shown in FIG. 6 (d), the musical tone control signal generator 70 may be disposed by bonding or the like on the back side of the hitting surface of the electronic bass drum, instead of the pedal device that performs the performance operation. Further, as shown in FIG. 6E, a musical tone control signal generator 70 may be disposed on the back surface of the electronic cymbal pad 67 by bonding or the like. Alternatively, as shown in FIG. 6 (f), the musical sound control signal generator 70 may be used separately on the back surface of the pad 69 of the electronic snare drum and the inside of the shell-shaped housing 59. . For example, the power generation means 71 is disposed on the back surface of the pad 69 by adhesion or the like, and the acquisition means 72 and the output means 73 are disposed on the inside of the housing 59 by adhesion or the like. As shown in FIG. 6 (d) and FIG. 6 (e), when generating electric power using the impact force of a beater or a stick, instead of the mechanism described in FIG. What is necessary is just to change a striking power into electric power. In other words, the power generation mechanism may be configured to appropriately generate power according to the operation mode and the input mode. The arrangement and fixing method of the musical tone control signal generator 70 are not limited.

  As shown in FIGS. 6E and 6F, in the musical tone control signal generator, the pads 67 and 69 are usually provided with vibration sensors 68 made of piezoelectric elements or the like at a commercially available stage. Yes. When power generation is performed by the musical tone control signal generator 70, it is not necessary to use the vibration sensor 68 that originally exists. However, when the vibration sensor 68 can detect a striking operation or the like and can obtain sufficient power to output the detection signal, the vibration sensor 68 may be used to generate power.

  Although the present invention has been described in detail based on preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms within the scope of the present invention are also included in the present invention. included.
