(First embodiment)
A first embodiment of the present invention will be described. In the first embodiment, based on the data recorded by the performance recording device 10 shown in FIG. 1, a performance device 40 (described later) plays a trumpet 16 which is a kind of wind instrument. The performance recording apparatus 10 includes a first pressure sensor 12, a second pressure sensor 14, a third pressure sensor 17, a piston displacement sensor 15, and a data recorder 20. As shown in detail in FIG. 2, the first pressure sensor 12 and the second pressure sensor 14 are attached to a measurement mouthpiece 18. The measuring mouthpiece 18 is used in place of the actual mouthpiece 61 (described later) of the trumpet 16. A measuring adapter 19 is interposed between the measuring mouthpiece 18 and the trumpet main body 16a. The third pressure sensor 17 is attached to the measurement adapter 19. When playing the trumpet 16, the performer 11 brings the lips 23 into contact with the lip contact portion 24 of the measurement mouthpiece 18 and vibrates the lips 23 while blowing air into the measurement mouthpiece 18. When the lips 23 are vibrated while air is blown into the measurement mouthpiece 18, a musical tone having the frequency (scale) is generated from the trumpet 16. The frequency of the lips 23 is adjusted by changing the hardness of the lips 23. When the frequency of the lips 23 is adjusted, the frequency of the musical sound generated by the trumpet 16 changes accordingly.

  The first pressure sensor 12 detects the pressure in the measurement mouthpiece 18 over time. The temporal resolution possessed by the first pressure sensor 12 is sufficiently higher than the frequency of the pressure change caused by the vibration of the lips 23. The second pressure sensor 14 is disposed downstream of the first pressure sensor 12 and detects the pressure of the air flowing through the measurement mouthpiece 18 over time. The third pressure sensor 17 detects the pressure of the air flowing through the measurement adapter 19 over time. From the detected pressure difference between the second pressure sensor 14 and the third pressure sensor 17, the flow rate of the air blown into the trumpet 16 by the player 11 is estimated. Specifically, the correspondence relationship between the flow rate of the air flowing through the trumpet 16 and the detected pressure difference between the second pressure sensor 14 and the third pressure sensor 17 is measured in advance. Then, the flow rate of air blown into the trumpet 16 is estimated from the detected pressure difference between the second pressure sensor 14 and the third pressure sensor 17 and the corresponding relationship described above. The second pressure sensor 14 and the third pressure sensor 17 have a temporal resolution enough to follow the flow rate change. A flow rate of air blown into the trumpet 16 can also be detected using a sensor other than the pressure detection type (for example, a flow rate sensor).

As shown in FIG. 1, the displacement amount (stroke amount) of the pistons 31, 32, 33 when the player 11 pushes down the pistons 31, 32, 33 of the trumpet 16 is continuously measured by the piston displacement sensor 15. Detected. The piston displacement sensor 15 is provided for each of the pistons 31, 32, and 33 (in FIG. 1, the piston displacement sensor 15 is illustrated integrally). The piston 31 is operated by the index finger, the piston 32 is operated by the middle finger, and the piston 33 is operated by the ring finger.
FIG. 3 illustrates the piston displacement sensor 15. The piston displacement sensor 15 includes a rack 26, a pinion 27, and an encoder 28. The rack 26 is fixed to the lower ends of the pistons 31, 32 and 33. The rack 26 and the pinion 27 are meshed with each other. When the pistons 31, 32, 33 are displaced, the rack 26 is also displaced accordingly. When the rack 26 is displaced, the pinion 27 rotates and the encoder 28 detects the rotation angle. The rotation angle of the pinion 27 corresponds to the pistons 31, 32 and 33. Therefore, the encoder 28 can detect the displacement amount of the pistons 31, 32, 33 from the rotation angle of the pinion 27.
When the pistons 31, 32, and 33 are operated, the tube length of the trumpet 16 is adjusted, and the resonance frequency of the trumpet 16 changes. When the resonant frequency of the trumpet 16 and the frequency of the lip 23 of the performer 11 resonate, a beautiful musical tone is generated at a high volume.
As shown in FIG. 1, detection values of the first pressure sensor 12, the second pressure sensor 14, the third pressure sensor 17, and the piston displacement sensor 15 are recorded in the data recorder 20.

  FIG. 4 illustrates data recorded in the data recorder 20. The vertical axis of the graph shown in FIG. 4 is estimated from the pressure of the mouthpiece 18 (mouthpiece pressure) measured by the first pressure sensor 12 and the detected values of the second pressure sensor 14 and the third pressure sensor 17, respectively. This corresponds to the flow rate of the air blown into the mouthpiece 18 (mouthpiece flow rate) and the displacement of the pistons 31, 32, 33. The horizontal axis shows the passage of time. In FIG. 4, first, the piston 33 is operated (pressed down) by the ring finger. At this time, the mouthpiece pressure vibrates with a small amplitude, and the mouthpiece flow rate is stable at a small value. That is, the performer 11 blows air weakly into the measurement mouthpiece 18. When the operation of the piston 33 with the ring finger is completed, the piston 31 is operated with the index finger, and at the same time, the amplitude of the mouthpiece pressure increases and the mouthpiece flow rate also increases. That is, the player 11 blows air strongly into the measurement mouthpiece 18. The frequency of the mouthpiece pressure at this time is lower than when the previous piston 33 is operated (the interval in the time passage direction of the mouthpiece pressure curve is wide). Thus, the trumpet 18 is played by the player 11 operating the pistons 31, 32, 33 while adjusting the flow rate of air to be blown and the vibration frequency of the lips 23 while blowing air into the measuring mouthpiece 18. The

The performance device 40 will be described. As shown in FIG. 5, the performance device 40 includes a performance actuator 42, an air cylinder 44, a flow valve 46, a control unit 43, a reading device 45, an amplifier 51, artificial fingers 52, 53, 54, finger actuators 55, 56, 57.
As shown in FIG. 6, the performance actuator 42 includes a casing 62 and an excitation unit 63 accommodated in the casing 62. In the casing 62, a disk-shaped member 65 and a substantially disk-shaped mouthpiece support member 66 are fastened to both ends of a cylindrical member 64 with a screw 67, and an accommodation space is formed therein. The mouthpiece support member 66 has a through hole 66a formed at the center and a recess 66b having a circular cross section on the accommodation space side. Further, the mouthpiece support member 66 is formed with a port 81 opened to the outside, and a hole 82 for communicating the port 81 and the recess 66b.

  The excitation unit 63 includes a plurality of bolts 74, a core holder 71, a core 72, a permanent magnet 73, a membrane film 78, a ring 79, and a coil 68. One end of the bolt 74 is screwed into the mouthpiece support member 66. The main body 71a of the core holder 71 has a cylindrical shape, and a flange-like flange 71b is formed at one end thereof. The flange 71 b is fixed to the other end of the bolt 74 by nuts 76 and 77. The core 72 is a cylindrical member having a recess 72 a and is fixed to the core holder 71. The permanent magnet 73 is fixed to the recess 72 a of the core 72. The membrane film 78 is a flexible film, and a plurality of holes for passing bolts 74 are formed in the outer peripheral portion. The membrane film 78 is stretched so as to cover the recess 66 b of the mouthpiece support member 66 while being interposed between the ring 79 inserted through the bolt 74 and the mouthpiece support member 66. The ring 79 is fixed by a nut 75.

The mouthpiece 61 of the trumpet 16 is inserted through the through hole 66 a of the mouthpiece support member 66. In this state, the lip-shaped lip contact portion 61 a formed at the end of the mouthpiece 61 is in contact with the membrane film 78, and the shim 83 is interposed between the lip contact portion 61 a and the mouthpiece support member 66. Is disposed in the recess 66b. The mouthpiece support member 66 is formed with a screw hole 66c penetrating from the outside to the through hole 66a. The mouthpiece 61 is fixed to the mouthpiece support member 66 by the tip of the screw 80 tightened in the screw hole 66 c coming into contact with the mouthpiece 61. If the mouthpiece 61 is slid in the axial direction before the screw 80 is tightened, the axial positional relationship between the mouthpiece 61 and the mouthpiece support member 66 can be adjusted. If the thickness of the shim 83 is adjusted in advance, the positional relationship between the mouthpiece 61 and the mouthpiece support member 66 can be easily adjusted. When the thick shim 83 is used, the membrane film 78 and the lip contact portion 61a come into strong contact (the contact pressure is large). When the thin shim 83 is used, the membrane film 78 and the lip contact portion 61a come into weak contact (contact pressure is reduced).
The coil 68 has one end bonded to the membrane film 78 and the other end arranged in a space formed by the permanent magnet 73 and the recess 72 b of the core 72. The coil 68 is connected to the amplifier 51 by a lead wire (not shown).

The control unit 43 shown in FIG. 5 is a computer having a CPU, a ROM, a RAM, and the like. The reading device 45 is connected to the control unit 43, and the detection data of the first pressure sensor 12, the second pressure sensor 14, the third pressure sensor 17, and the piston displacement sensor 15 recorded by the data recorder 20 of the performance recording device 10. Are read through a storage medium (for example, a CD-ROM).
The port 81 of the performance actuator 42 and the air cylinder 44 are connected by an air supply channel 84. The flow valve 46 is attached in the middle of the air supply channel 84. The flow valve 46 is controlled by the control unit 43. Further, the control unit 43 controls the AC power applied to the coil 68 of the performance actuator 42 via the amplifier 51.
The artificial fingers 52, 53, 54 are connected to the plungers 55a, 56a, 57a of the finger actuators 55, 56, 57, respectively. The tips of the artificial fingers 52, 53, 54 are in contact with the pistons 31, 32, 33 of the trumpet 16. When the plungers 55a, 56a, 57a of the finger actuators 55, 56, 57 are controlled by the control unit 43 to expand and contract, the artificial fingers 52, 53, 54 operate the pistons 31, 32, 33. Various types of finger actuators 55, 56, 57 (for example, pneumatic drive, hydraulic drive, motor drive, solenoid drive, etc.) can be used.

Instead of the artificial fingers 52, 53, and 54 and the finger actuators 55, 56, and 57, for example, the pistons 31, 32, and 33 can be operated by a piston operating device 85 shown in FIG.
The piston operating device 85 includes an operating member 86, a pinion 87, a speed reducer 88, a motor 89, and an encoder 90. The operating member 86 includes a rack 86b in which a pressing portion 86a is formed at one end and a tooth shape extends linearly. The operation member 86 is disposed at a position where the pressing portion 86 a contacts the pistons 31, 32, 33.
The motor 89 is controlled by the control unit 43. The reducer 88 decelerates the rotation speed of the motor 89 and outputs it from the output shaft 88a. The output shaft 88a drives the pinion 87. The rack 86 b of the operation member 86 is engaged with the pinion 87. The encoder 90 is connected to the rotation shaft of the motor 89, detects the rotation state of the motor 89, and transmits it to the control unit 43.
According to the piston operating device 85 configured in this way, when the motor 89 rotates under the control of the control unit 43, the pinion 87 rotates accordingly. When the pinion 87 rotates, the rack 86 meshing with the pinion 87 moves in the axial direction, and the pistons 31, 32, and 33 are operated. By adjusting the rotational speed, rotational acceleration, rotational direction, and rotation duration of the motor 89, the pistons 31, 32, and 33 can be finely operated.

When AC power is applied to the coil 68 of the excitation unit 63 of the performance actuator 42, the coil 68 vibrates in the axial direction, and the membrane film 78 bonded thereto also vibrates. When the membrane film 78 vibrates, the air pressure in the mouthpiece 61 vibrates. When pressurized air is supplied to the port 81, a gap is formed between the membrane film 78 and the lip contact portion 61a of the mouthpiece 61, and air passes through the gap. When air is supplied to the port 81 while the membrane film 78 is vibrating, the gap (air passage area) between the membrane film 78 and the lip contact portion 61a varies. When the air passage area fluctuates, the flow rate of air flowing into the mouthpiece 61 fluctuates accordingly, and the pressure in the mouthpiece 61 also vibrates.
The frequency of the AC power applied to the coil 38 and the frequency of the membrane film 78 are in good agreement. Therefore, when the control unit 43 adjusts the frequency of the AC power applied to the coil 38, the frequency of the membrane film 78 can be controlled. A tone corresponding to the frequency of the membrane film 78 is generated from the trumpet 16. The air flow rate supplied to the port 81 is adjusted by the control unit 43 controlling the flow rate valve 46.
The air flow rate supplied to the port 81 is proportional to the amplitude of air vibration in the mouthpiece 61. For this reason, when the air flow rate supplied to the port 81 is increased, the sound volume generated by the trumpet 16 is increased, and when the air flow rate supplied to the port 81 is decreased, the sound volume generated by the trumpet 16 is decreased. When the pistons 31, 32, and 33 are operated, the tube length of the trumpet 16 is adjusted, and the resonance frequency of the trumpet 16 changes. When the air frequency in the mouthpiece 61 and the resonance frequency of the trumpet 16 match, a beautifully resonated musical sound is generated.

  As described above, the reading device 45 stores the detection data of the first pressure sensor 12, the second pressure sensor 14, the third pressure sensor 17, and the piston displacement sensor 15 recorded by the data recorder 20 of the performance recording device 10 as a storage medium. Read through. Using these detection data, the performance device 40 can play the trumpet 16 in the same manner as the player 11 performs. Specifically, the control unit 43 vibrates the membrane film 78 at the frequency detected by the first pressure sensor 12 based on the detection data read by the storage device 45, and the second pressure sensor 14 and the third pressure. Air having a flow rate detected by the sensor 17 is supplied to the port 81. Further, the control unit 43 controls the finger actuators 55, 56, and 57 to operate the pistons 31, 32, and 33 of the trumpet 16 with the amount of displacement detected by the piston displacement sensor 15. In this way, the state (air frequency, amplitude, air flow rate) in the measurement mouthpiece 18 when the player 11 plays the trumpet 16 and the operation of the pistons 31, 32, 32 are reproduced. The trumpet 16 can be played.

(Second embodiment)
A performance apparatus according to the second embodiment of the present invention will be described. The content overlapping with the performance device 40 of the first embodiment is omitted, and the characteristic part of the present embodiment will be mainly described. In the second embodiment, a performance actuator 112 is used instead of the performance actuator 42 of the first embodiment.
As shown in FIG. 8, the performance actuator 112 includes an open / close valve 142, a slider portion 143, and a pipe 144. The on-off valve 142 includes a valve main body 145, a sleeve 146, a valve actuator 147, and a spring 148. The valve body 145 is formed with an air channel 153 that allows the inlet port 151 and the outlet port 152 to communicate with each other, and a guide hole 145 a having a circular cross section orthogonal to the air channel 153. An air supply channel 84 is connected to the inlet port 51. The sleeve 146 is formed with a shaft portion 146a, an opening / closing portion 149 bulging from the shaft portion 146a, and guide portions 159 and 159 bulging from the shaft portion 146a with the opening / closing portion 149 interposed therebetween. The opening / closing part 149 and the guide parts 159, 159 have a circular cross section. The opening / closing part 149 is formed with a transition part 149a that reaches the maximum diameter of the opening / closing part 149 while gradually changing from the shaft part 146a. The guide portions 159 and 159 guide the sleeve 146 in the axial direction by making sliding contact with the guide hole 145a. One end of the sleeve 146 is attached to the valve actuator 147. The spring 148 is interposed between the guide portion 159 on the counter valve actuator 147 side and the end portion of the guide hole 145a. In the state where the sleeve 146 is disposed at the position shown in FIG. 8, the opening / closing part 146 a closes the air flow path 153.

  The valve actuator 147 is connected to the control unit 43 via the amplifier 51, and drives the sleeve 146 with a built-in solenoid. The control unit 43 outputs a drive signal to the valve actuator 147. The valve actuator 147 to which the drive signal is input moves the sleeve 146 to the counter valve actuator 147 side. FIG. 9 illustrates a state in which the sleeve 146 has moved to the counter valve actuator 147 side. In this state, the spring 148 is contracted by being pushed by the sleeve 146 and the opening / closing part 146a of the sleeve 146 is moved from the closed position, whereby the air flow path 153 is opened. When the current of the drive signal input to the valve actuator 147 is reversed, the sleeve 146 moves toward the valve actuator 147 while being biased by the spring 148, closes the air flow path 153, and further moves toward the valve actuator 147. Open the air flow path 153.

The slider unit 143 includes a slider 156, a drive gear 158, a motor 166, and a mouthpiece 155. The slider 156 includes a cylindrical slider body 156a and a slider gear 156b provided at one end of the slider body 156a. A screw 156c is formed on the outer peripheral surface of the slider body 156a. The slider 156 is formed with a hole 161 penetrating in the axial direction. The mouthpiece 155 is used in place of the actual mouthpiece 61 of the trumpet 16, and is inserted into the mouthpiece mounting portion 16 b of the trumpet 16. A screw 155 a is formed on the inner peripheral surface of the mouthpiece 155. The slider 156 is screwed into the mouthpiece 155 by using the screw 155a and the screw 156c of the slider main body 156a. Therefore, when the slider 156 is rotated, the slider 156 moves back and forth with respect to the mouthpiece 155.
The drive gear 158 is coupled to the rotation shaft of the motor 166 and meshes with the slider gear 156 b of the slider 156. The motor 66 is connected to the control unit 43. FIG. 8 illustrates a state in which the slider 156 moves forward and enters the front air chamber 157 of the mouthpiece 155 deeply. FIG. 9 shows a state where the slider 156 is retracted. As the slider 156 moves forward, the volume of the front air chamber 157 decreases. When the slider 156 moves backward, the volume of the front air chamber 157 increases.
One end 144 a of the pipe 144 is fixed to the outlet port 152 of the opening / closing valve 142. The other end 144 b of the pipe 144 is inserted through the through hole 161 of the slider 156. Accordingly, the air that has flowed out of the outlet port 152 passes through the pipe 144 and flows into the front air chamber 157 of the mouthpiece 155. When the slider 156 moves back and forth, the slider 156 moves relative to the pipe 144.
The opening / closing valve 142 and the motor 166 of the slider portion 143 are supported by a support member (not shown) coupled to the trumpet 16.

When the valve actuator 147 of the open / close valve 142 vibrates the sleeve 146 while supplying air from the air supply flow path 84 to the inlet port 151 of the open / close valve 142, the air flow path 153 is opened and closed, and the front air chamber of the mouthpiece 155. The pressure of the air supplied to 157 vibrates. In this case, the frequency of the air pressure is twice that of the sleeve 146. This is because the air flow path 153 is opened and closed twice each time the sleeve 146 moves one stroke. For example, if the frequency of the sleeve 146 is 100 Hz, the frequency of the air pressure supplied to the front air chamber 157 is 200 Hz. Since the vibration frequency of the air pressure in the front air chamber 157 and the vibration frequency of the sleeve 146 are in this relationship, even if the vibration frequency of the sleeve 146 is low, the vibration frequency of the air pressure supplied to the front air chamber 157 is reduced. Can be high.
When the pressure in the front air chamber 157 vibrates, the trumpet 16 generates a musical tone with that frequency. For example, a “do” tone is generated. The amplitude of the air vibration in the mouthpiece 155 is proportional to the supplied air flow rate. Therefore, when the flow rate of the air flow supplied to the mouthpiece 155 is increased by controlling the flow valve 46, the volume generated by the trumpet 16 increases. When the flow rate of the supplied air flow decreases, the volume generated by the trumpet 16 decreases. For example, if the air flow rate is increased while the “le” tone is being emitted, the volume of the “re” increases. Even if the amplitude of the sleeve 146 of the on-off valve 142 is changed, the amount of air supplied to the front air chamber 157 can be adjusted. For example, when the amplitude of the sleeve 146 is reduced, the valve opening area of the on-off valve 142 is reduced. Therefore, the air flow rate supplied to the mouthpiece 155 is reduced. If both the flow valve 46 and the open / close valve 142 are simultaneously controlled, the air flow rate can be adjusted more finely.

  As described above, the opening / closing part 149 of the sleeve 146 of the opening / closing valve 142 is provided with the transition part 149a. By selecting various shapes of the transition portion 149a, it is possible to finely adjust the pressure change of the air supplied from the opening / closing valve 142 to the mouthpiece 155. For example, when the transition portion 149a is lengthened in the axial direction, when the opening / closing valve 142 is opened / closed, the switching of the air flow path 153 does not occur abruptly, so the rise / fall of the air pressure change becomes gentle ( The shape of the peaks and valleys of pressure fluctuations becomes gentle.) The shape of the transition part 149a is not limited to the linear shape as illustrated in FIGS. For example, the transition portion 149a can be formed by a curve, a combination of a curve and a straight line, or the like. By selecting the shape of the transition unit 149a, the music generated by the trumpet 16 can be finely tuned.

The measurement mouthpiece 18 and the performance device 40 may be directly connected, and the performance device 40 may play the trumpet 16 in parallel with the player 11 playing the trumpet 16 (in real time). If it does in this way, according to a performance environment, the performance apparatus 40 can be made to perform an ad lib.
The performance recording device 10 and the performance device 40 of the present invention can also be suitably used to play wind instruments other than the trumpet 16 (for example, trombone, horn).
When the performance device of the present invention is applied to a robot, the robot can play a wind instrument.
The sleeve 46 of the opening / closing valve 142 may not completely block the air flowing through the air flow path 53. That is, the air flowing through the air flow path 53 may be vibrated so as to have a large flow rate and a small flow rate.
The transition portions 149 a and 149 a of the sleeve 146 of the on-off valve 142 may not be formed symmetrically with respect to the vibration center of the sleeve 46.
When the present invention is applied to a wind instrument having a slider such as a trombone, an artificial arm is used instead of the artificial fingers 52, 53, and 54.
