2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Publication No. 54-19338, for example, a shoe-type musical instrument has been considered which produces a musical sound by gesturing the foot. This musical instrument has an electronic circuit and a speaker housed inside a boat-shaped case, and a plurality of switches corresponding to the note names are arranged on the lower side surface of the case. A melody is played by turning on a switch by an operation.

This conventional shoe-type musical instrument merely switches the note names to be pronounced, but as another conventional technique,
In response to the electronic musical instrument system technology in which musical tone control such as the volume and tone color of musical tones is common, musical tone control of electronic musical instrument systems by gesturing a foot has been considered. For example,
Japanese Unexamined Patent Publication No. 9-68973 discloses a music sound in which a shoe insole type foot sensor equipped with a piezoelectric sensor is mounted in the shoe, and the pressure applied to the piezoelectric sensor by the tip of the foot or the heel is detected to control a musical sound. A controller is disclosed.

[0004]

However, this conventional tone control apparatus has the following problems because the sensor section has the structure shown in FIG. That is, the displacement face plate b to which the piezoelectric sensor a is fixed is arranged to face the reference face plate c that contacts the sole contact surface of the shoe with the spacer d interposed therebetween. The spacer d is formed only on a part of the opposing surfaces of the reference face plate c and the displacement face plate b, and the displacement face plate b is cantilevered.
Therefore, the sensor portion has peculiarity in the direction in which the external force is applied, and in particular, considering the case where the force is mainly applied to the spacer d portion, the dead zone is present in the spacer d portion. Therefore, even if the same force is applied, the output level will be different if the stepping direction and position of the foot are different. In other words, this conventional tone control device has a quirky sensor.

Further, since this conventional tone control apparatus uses an insole type foot sensor, it has the following problems. Even if the performer steps in the same way and tries to operate at the intended part of the sole, the position of the tip of the foot or the heel slightly deviates from the piezoelectric sensor depending on the stepping angle and direction, which is not intended Music control may result. In other words, it lacked fidelity as an input device based on a gesture of a foot, that is, an input interface.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a shoe-type footwear musical sound control device which can obtain substantially the same output if the applied pressure is the same even if the direction of external pressure is different.

A bulging portion 132 bulging into a thin truncated cone shape is formed at the center of the plate-shaped pressing portion 13, and a positioning hole 133 is further formed at the center thereof.

The sensor fixing member 12 and the plate-like pressure member 13 are brought into contact with the sensor fixing member 12 by the bulging portion 132 of the plate-like pressure member 13, and the positioning projection 122 is fitted into the positioning hole 133. , The bulging portion 132 is fixed to each other by spot-welding at three places around the circumference of three parts (portion indicated by a chain double-dashed line in FIG. 3A). The piezoelectric sensor 14 is fixed to the central surface of the sensor fixing body 12 after spot welding. Further, at three locations around the plate-shaped pressure applying portion 13, there are formed positioning projections 134 having tapered ends, and the tips of the positioning projections 134 are provided at the plate-shaped pressing portion 1.
3 is slightly projected from the outer circumference. Then, as shown in FIG. 1, a circular tray-shaped stainless cover 17 serving as a bottom plate is attached to the bottom surface of the plate-shaped pressing unit 13, and the cover 17 is attached to the plate-shaped pressing unit 13. When the cover 17 and the plate-shaped pressing portion 13 are fitted to each other, the positioning protrusions 134 are used to position each other. Note that the cover 17 has through holes 171 formed at three locations corresponding to the screw holes 121 of the sensor fixing body 12 and the through holes 131 of the plate-like pressure portion 13.

Now, the assembly of this device will be described. First, the screw fixing holes 121 of the sensor fixing body 12 and the through holes 131 of the plate-like pressure applying portion 13 are aligned with each other, and the sensor fixing body 12 and the plate-like pressure applying portion are spot-welded with their facing surfaces aligned to be integrated. The piezoelectric sensor 14 is attached to the metal surface side of the piezoelectric sensor 14 and the sensor fixing body 12 so as to face each other. As a result, the piezoelectric sensor 14, the sensor fixing body 12, and the plate-shaped pressing portion 13 are integrally molded. The lead wire 141 of the piezoelectric sensor 14 is attached to this, and an annular annular elastic body 15 formed of urethane rubber or the like is attached to the peripheral edge of the plate-shaped pressure portion 13 on the sensor fixed body 12 side with double-sided tape or the like. In addition, in the portion of the lead wire 141, the annular elastic body 15 is arranged between the lead wire 141 and the plate-shaped pressing portion 13. Next, the plate-like pressure unit 1
The through holes 131 of No. 3 and the through holes 171 of the cover 17 are aligned with each other, and the plate-shaped pressing portion 13 is covered with the cover 17, for example, by a double-sided tape. Then, the sensor fixing body 12 is fitted inside the rim 112c of the sensor support portion 112 of the sensor case 11, and the through hole 171 of the cover 17, the through hole 131 of the plate-like pressing portion 13 and the screw fixing of the sensor fixing body 12 are fixed. The screw 16 (FIG. 1) is screwed into the screw hole 112a of the sensor case 11 through the hole 121 (3
(Location), and the sensor fixing body 12 is attached to the sensor case 11. At this time, the lead wire 141 (FIG. 1) of the piezoelectric sensor 14 is drawn to the outside through the lead wire drawing groove 114 of the sensor case 11. A rubber dump cover 42, which will be described later, is adhered to the bottom surface of the sensor case 11 to prevent dust and the like from entering through the through hole 171 and prevent the edge of the through hole 171 from damaging the floor or the like. Is planned.

As described above, the sensor case 11, the sensor fixing body 12, the plate-shaped pressing portion 13, the piezoelectric sensor 14, the annular elastic body 15 and the cover 17 become an integral sensing device, which is attached to the floor facing portion 10. To be There are various conceivable methods for attaching the sensing device to the floor facing portion 10, but in the embodiments described below, the sensing device is directly attached to the sole of the shoe, or the sensing device is attached to the band and the band is optional. There is a method to attach it to the shoes of. FIG. 1 and FIG. 4 show a case where the belt is attached by a band, and a band 72 made of cloth is arranged on the sensor case 11 side and the band 72 is made of stainless steel.
7 and the sensor case 11 to sandwich the bottom plate 77 with the screw 19
(FIG. 4) is screwed at the position of the screw hole 112b (FIG. 2). If you want to attach it directly to the sole of your special shoe,
For example, the tip of the screw 16 in FIG. 1 is projected from the sensor case 11, and before the dump cover 42 is adhered, the screw 16 and an adhesive or the like are directly adhered and fixed to the floor facing portion 10 of the shoe, and then the dump cover 42 is attached. The cover 42 is adhered.

As described above, the piezoelectric sensor 14 is fixed to the sensor fixing body 12, and the sensor fixing body 12 is elastically deformable attached to the sensor case 11 fixed to the floor facing portion 10. It becomes a state. Further, both the plate-shaped pressing portion 13 and the sensor fixing body 12 are disk-shaped and both are radial, and the plate-shaped pressing portion 13 and the sensor fixing body 12 are fixed to each other at the central portion. Further, due to the bulging portion 132 of the plate-shaped pressing portion 13, the plate-shaped pressing portion 13 and the sensor fixing body 12 have their peripheral portions (the plate-shaped pressing portion peripheral portion 13).
A and the peripheral portion 12A of the sensor-fixed body is the sensor-fixed body 12
Are provided so as to face each other with a space S that is deformable within the elastic deformation of.

FIG. 4 shows B in FIGS. 2 (A) and 3 (A).
FIG. 5 is a side sectional view corresponding to the direction of the arrow B, and FIG. 5 is an operation diagram of the embodiment showing a shape change of the side section. The operation of the embodiment will be described based on the drawing. In FIG. 5, the thickness and the like are exaggerated and details are omitted for easy understanding. FIG. 5 (A) shows a state in which no external force is applied. FIG. 5B shows a state in which an external force (arrow) is applied inward from a part of the peripheral edge of the cover 17, the annular elastic body 15 is deformed, and the plate-shaped pressing portion 13 is swollen. While the portion 132 itself is also deformed, the bulging portion 132 applies a pressing force to the central portion of the sensor fixing body 12 (displacement amount A). Then, the sensor fixing body 12 elastically deforms so that the piezoelectric sensor 14 side swells.

FIG. 5C shows a state in which an external force is further applied from the state of FIG. 5B, and the elastic deformation of the sensor fixing body 12 progresses (displacement amount B, B> A), and the sensor fixing body is changed. The peripheral edge portion of 12 abuts on the peripheral edge portion of the plate-shaped pressing portion 13, and the sensor fixing body 12 is no longer deformed. That is, both peripheral portions of the sensor fixing body 12 and the plate-shaped pressing portion 13 serve as stoppers. In this way, the piezoelectric sensor 14 is deformed together with the sensor fixing body 12, and the piezoelectric sensor 14 generates piezoelectric electricity due to the piezoelectric effect and is output from the lead wire 141. Such an action is the same action even if an external force is applied to any part of the peripheral edge of the cover 17, and the sensor fixed body 1
Since an external force is applied to the central part of 2, the output of the piezoelectric sensor 14 becomes a similar output signal if the force is the same.

Further, FIG. 5D shows a case where an external force is applied to the center of the lower surface of the cover 17 or the entire lower surface. In this case, the gap between the sensor fixing body 12 and the plate-like pressure portion 13 is displaced so as to be constant as a whole (C1 = C).
2) Mainly, the sensor fixing body 12 is deformed and elastically deformed so that the piezoelectric sensor 14 side swells around the center thereof,
The piezoelectric sensor 14 produces an output. Even if the sensor fixing body 12 and the piezoelectric sensor 14 are deformed as described above, the lead wire 141 of the piezoelectric sensor 14 is attached to the sensor case 11 because the recess 115 (see FIG. 2) is formed in the sensor case 11. There is no contact.

The sensing device of the above embodiment is attached to the floor facing portion 10 of the shoe. For example, when a light tap is applied to input, the displacement of the sensing device is:
5 (A) to 5 (B) and the external force disappears,
It returns to the state of FIG. In the process, alternating vibrations are repeated. That is, the vibration is attenuated while repeating the states of FIGS. 5A and 5B, and an output signal corresponding to the vibration is obtained from the piezoelectric sensor 14. Depending on the tapping method, a pulse-like signal whose displacement and vibration are almost the same can be obtained. In this case, the displacement signal has different polarities for going and returning, but only "going (when stepping on)" is detected. Then, as the processing of the output signal of the piezoelectric sensor 14, for example, the envelope of the output signal is detected, and the trigger signal and the level signal are detected from the envelope to control the pronunciation of a musical sound.

As described above, since the plate-shaped pressing portion 13 and the sensor fixing member 12 are both radial (circular in the above example) and are fixed at the central portion thereof, the cover 17 (and the plate-shaped pressing member) are fixed. The external force applied to the pressure portion 13) is the plate-shaped pressure portion 13
The pressure is transmitted from the central part of the sensor to the central part of the sensor fixing body 12. As a result, the sensor fixing body 12 is deformed centering on the central portion thereof, and the piezoelectric sensor 14 is also deformed similarly. Therefore, if the external force is applied to the same extent, the piezoelectric sensor 14 can be applied to any part of the cover 17 to which the external force is applied.
Since the same signal is output from, the same tone control is performed for the same operation. That is, the electronic musical instrument sensing device has good operability and no habit.

The annular elastic body 15 is the sensor case 11.
Since it is sandwiched between the flange portion 113 and the plate-shaped pressing portion peripheral portion 13A of the plate-shaped pressing portion 13, dust and foreign matter enter the space S between the plate-shaped pressing portion 13 and the sensor fixing body 12. Can be prevented. Further, since the annular elastic body 15 is elastically deformed and closely fixed to the lead wire 141 of the piezoelectric sensor 14 at the portion of the lead wire drawing groove 114, the lead wire 141 is formed.
Can be prevented from moving.

In the above embodiments, the sensor fixing body and the plate-shaped pressing portion are circular, but the sensor fixing body and the plate-shaped pressing portion are triangular, square, ..., Polygonal, circular, Y. Mold,
A substantially rotationally symmetrical shape such as a star shape may be used.

Further, in the above embodiment, the pressure is applied to the sensor fixing body 12 via the disk-shaped plate-like pressure portion 13, but, for example, as shown in FIG. The spacer 18 may be arranged in the center between the sensor fixing body 12 and the cover 17. in this case,
Both peripheral portions of the cover 17 and the sensor fixing body 12 are provided so as to face each other with a gap, and the cover 17 and the spacer 18 correspond to the plate-shaped pressing portion of claim 1. In this embodiment, it is desirable that the cover 17 has a shape or material having elasticity and rigidity. This is because, if an external force is partially applied to the cover 17 beyond the elastic limit, the deformation will not return even if the external force is removed. Therefore, it is better to increase durability so that it does not occur. If such measures are taken, this embodiment can be made superior to the first embodiment (FIGS. 1 to 5). That is, the spacer 18 does not need to be so precise in shape and size, and the sensor fixing body 12 is fixed to the sensor case 1 via the spacer 18 and the annular elastic body 15.
It is only necessary to fix it to cover 1 with cover 17. The joining means may be an adhesive. Therefore, the assembly can be simplified.
