BEST MODE FOR CARRYING OUT THE INVENTION Next, preferred embodiments of the present invention will be described with reference to the drawings.

A: Details of Embodiment FIG. 1 is a diagram showing a tap sound producing system 100 according to the present invention. As shown in FIG. 1, the tap sound producing system 100 is mounted on a foot of a user U. It has a tap shoe 10 and a tap sound output device 20 for outputting a tap sound. The tap shoes 10 are tap shoes 10-R for the right foot and tap shoes 10-L for the left foot.
However, since the contents according to the present invention are the same, they are simply expressed as tap shoes 10 unless otherwise specified. Hereinafter, the contents of the tap shoe 10 according to the present invention and the contents of the tap sound output device 20 will be described.

A1: Tap Shoes 10 FIG. 2 shows a tap shoe 1 according to an embodiment of the present invention.

Here, the shape of a general tap shoe is almost fixed, and the position and shape of the tip attached to the sole of the shoe are almost the same. The chips C1 and C2 of the tap shoe 10 according to the present invention are also attached at the same position as a general tap shoe and have substantially the same shape. Then, the microphones M1 and M2 are installed at positions close to the chips C1 and C2. Therefore, when the user (tap dancer) wearing the tap shoe 10 according to the present embodiment moves his / her foot, the chips C1 and C2 and the microphones M1 and M2 also move in accordance with the movement of the foot. That is,
Tap shoes (single holding part) 10 according to the present embodiment
At the chips C1 and C2 and the microphones M1 and M
The distance from 2 is almost constant. Further, in the present application, when the expression “single holding unit” is used, it does not mean that the holding unit itself is physically a single body (same body), but a series of cohesive sets that move with the movement of the user's body. It means the body. For example, the tap shoes 10 themselves are physically separated (tap shoes 10-L, 10-R) to be worn on each of the user's feet, but move with the movement of the user's feet. Since it is a series of cohesive aggregates, the expression “single holding unit” is used.

Like the general tap shoes, the chips C1 and C2 are provided on the toes and heels of the tap shoe 10, and generate a hitting sound (tapping sound) when hit by the user on the floor. It is supposed to do.
In addition, in the conventional tap shoe, a plate-shaped member made of metal (aluminum or the like) is used as the chips C1 and C2 so that a large tap sound is generated. However, in the tap shoe 10 according to the present embodiment. Since the tap sound output device 20 described later can control the volume of the tap sound, other members may be applied as the chips C1 and C2.

The microphones M1 and M2 are condenser microphones and are installed adjacent to the chips C1 and C2, respectively. Here, the condenser microphone is known as a component having a function of converting sound pressure into an electric signal by utilizing a change in capacitance of the condenser. In the present embodiment, the microphone M1 is provided to collect the hitting sound (tap sound) generated in the chip C1, and the microphone M2 collects the hitting sound (tap sound) generated in the chip C2. It is provided to do so. In the present embodiment, the microphone M1 outputs a signal (hereinafter referred to as a tap signal) Stap-1 obtained by converting the collected hitting sound (tap sound) into an electric signal to the transmission unit D. The microphone M2 also outputs a signal (tap signal) Stap-2 obtained by converting the collected tap sound into an electric signal to the transmission unit D.

The high frequency generation circuit 51 outputs the generated high frequency signal to the FM modulation circuit 52. Further, the addition unit 55 outputs to the FM modulation circuit 52 a tap signal Stap12 that is a composite addition of the tap signal Stap-1 supplied from the microphone M1 and the tap signal Stap supplied from the microphone M2.

The FM modulation circuit 52 is a high frequency generation circuit 51.
It is a circuit that performs FM modulation on the tap signal Stap12 supplied from the adder, using the high frequency signal supplied from. Then, the FM modulation circuit 52 outputs the tap signal Sta.
A signal Sfm45 obtained by applying FM modulation to p12 is multiplied by a multiplication circuit 53.
Output to. The multiplication circuit 53 is a circuit that multiplies the frequency of the supplied signal by a predetermined value. Here, the signal Sfm45 supplied from the FM modulation circuit 52 is doubled,
The 90 MHz FM signal Sfm90 is generated. After that, the FM signal Sfm90 is output to the air as a wireless signal (radio wave) Swireless via the antenna 54.

A2: About the tap sound output device 20 FIG. 4 shows an outline of the structure of the tap sound output device 20 which is configured corresponding to the above-described tap shoe 10. As shown in FIG. 4, the tap sound output device 20 includes a receiver 21, a signal processor 22, and a sound generator 23.

The receiver 21 has a function of receiving the wireless signal Swireless output from the tap shoe 10.
Although FIG. 5 is a circuit block diagram of the reception unit 21, as shown in FIG. 5, the reception unit 21 includes an antenna 31 and an FM demodulation circuit 32. The antenna 31 receives the wireless signal Swireless output from the tap shoe 10, and
The modulated electric signal S31 is output to the FM demodulation circuit 32. The FM demodulation circuit 32 performs FM demodulation processing on this signal S31 and obtains a signal S32 that is almost the same as the original tap signal Stap12. As described above, since the transmitter D of the tap shoe 10 performs the FM modulation processing at the predetermined frequency, the FM demodulation circuit 3
2 can perform FM demodulation processing on the signal S31 by using the clock signal of such a predetermined frequency.

The signal processing section 22 includes an FM demodulated signal S.
Predetermined amplification processing and noise removal processing are performed on 32. FIG. 6 shows a circuit block diagram of the signal processing unit 22.

It is composed of an amplifier and outputs a signal S41 obtained by amplifying the level (voltage level) of the signal S32 supplied from the FM demodulation circuit 32 by a predetermined factor. The noise removing circuit 42 is composed of a predetermined bandpass filter, and this bandpass filter has a tap signal S.
It is adjusted to correspond to the frequency band of tap21. That is, the noise removing circuit 42 includes the tap signal Stap21 among the signals S41 supplied from the amplifying circuit 41.
Only signals belonging to the frequency band of are extracted and output as signal S42. The noise removing circuit 42 removes the noise component generated when the FM modulation process and the FM demodulation process are performed, the howling noise component generated in the microphones M1 and M2 of the tap shoe 10, and the like.

The sound producing section 23 has a speaker function and outputs (emits) the content of the signal S42 supplied from the noise removing circuit 42, that is, a signal obtained by amplifying the volume of the tap sound generated by the user. More specifically, processing of converting the signal S42 supplied from the noise removal circuit 42 into a mechanical signal and emitting it as a musical sound is performed.

Incidentally, the tap shoe 1 according to the present embodiment.
0 is actually composed of the tap shoe 10-R for the right foot and the tap shoe 10-L for the left foot, and the radio signals Swireless-R and Swireless-from the tap shoes 10-R and 10-L, respectively. L is output to the tap sound generation device 20. However, if the FM modulation frequencies relating to the two wireless signals Swireless-R and Swireless-L are made different, the tap sound generation device 20

-While distinguishing L, each tap shoe 10-
R, 10-L tap signals Stap21-R, Stap21-
The signal relating to L can be reproduced.

As described above, according to the tap sound producing system 100 of the present invention, even when the tap sound of the tap shoe 10 is lower than the desired volume,
An electric signal obtained by absorbing the tap sound with the microphones M1 and M2 can be transmitted to the tap sound output device 20. Then, in the tap sound output device 20, after performing a predetermined amplification process on the electric signal, it can be converted into mechanical vibration and the tap sound can be emitted from the sounding unit 23.
Here, each of the microphones M1 and M2 is a chip C.
1 and C2 are installed near the microphones M1,
The M2 and the chips C1 and C2 operate in conjunction with the tap shoe 10. That is, the microphones M1, M
2 and the chips C1 and C2 are interlocked with the movement of the user's foot. Therefore, the distance between the microphones M1 and M2 and the chips C1 and C2, which are the main sound sources, does not change, and the problem that the volume of the chip sound absorbed by the microphones M1 and M2 varies does not occur. . In the tap sound generation device 20, since the tap sound actually generated by the movement of the foot of the user can be emitted, the tap sound generated by the subtle movement of the foot of the user is reflected. Sound processing can be performed.

B: Modifications The embodiment of the present invention has been described above, but this embodiment is merely an example and can be modified within the scope of the gist of the present invention. For example, the following may be considered as modifications.

(Modification 1) The materials of the chips C1 and C2 can be arbitrarily modified. In the above embodiment, the chips C1,
Although an aluminum plate-shaped member is given as an example of C2, a plate-shaped member made of another metal (iron, copper, or alloy) may be used, for example.
Further, it may be other than metal, and a wooden board may be adopted. In other words, if the impact sound (chip sound) is generated when the user hits the floor surface, the chips C1 and C are used.
It can be used as 2. That is, in the present embodiment, as long as some impact sound (chip sound) is generated when the user hits the floor surface, the chip sound is transmitted to the chip sound output device 20 and has a desired volume. The adjusted sound is output as a chip sound. Therefore, the materials of the chips C1 and C2 according to this embodiment are arbitrary. Instead of a plate-shaped member, a thin film of aluminum may be used. Further, the chips C1 and C2 may be made of different materials, such as an aluminum plate for the chip C1 and a wooden plate for the chip C2.

(Modification 2) The size, position and range of the chips C1 and C2 occupied in the tap shoe 10 can be arbitrarily modified. Although not particularly limited in the above-described embodiment, for example, the chips C1 and C2 may have various shapes such as a rectangular shape and a circular shape. In the above-described embodiment, the chips C1 and C2 are attached to two parts of the toe part and the heel part, as in a normal tap shoe,
A new chip may be attached to a place other than this. Further, the right foot portion and the left foot portion of the tap shoe 10 may have different sizes, positions, and ranges of the chips C1 and C2.

(Modification 3) Microphone M (M1, M
Regarding 2) as well, it is possible to arbitrarily modify. For example, the microphone M may be replaced with the vibration pickup P. The vibration pickup P is a member known as a pickup that has a function of detecting vibration and outputting it as an electric signal, and is composed of, for example, a piezoelectric element. In this modification, the vibration pickup P detects the vibration generated in the chip C (C1, C2) of the tap shoe 10 and outputs this as an electric signal. Here, since the vibration generated in the chip C corresponds to the chip sound (sound pressure vibration) generated when the user hits the chip C on the floor, the vibration pickup P is the microphone according to the above-described embodiment. It will play a role substantially equivalent to M. Therefore, even if the microphone M is replaced by the vibration pickup P, the same operation and effect as those of the above-described embodiment can be obtained. Further, FIG. 7 is a diagram schematically showing a positional relationship between the chip C and the vibration pickup P in the present modification. Since the vibration pickup P needs to detect the vibration itself generated in the chip C, it is desirable that the vibration pickup P and the chip C are in contact with each other as shown in FIG. 7A. Alternatively, as shown in FIG. 7B, it is desirable that the vibration pickup P and the chip C be in a semi-contact state with a cushioning material (or a conductive material) Z or the like. In any case,
The vibration pickup P and the chip C may be interlocked with each other so that the vibration pickup P can detect the vibration itself generated in the chip C. Note that FIG.
FIG. 6C is a diagram schematically showing the positional relationship between the chip C and the microphone M in the above embodiment. As shown in FIG. 7C, the microphone M is a chip C.
And a small distance Δd away from each other. This is because the microphone M needs to be installed near the chip C that is the main sound source to absorb the chip sound. On the other hand, when the microphone M is installed so as to be in contact with the chip C, vibration noise of the chip C is generated. The reason is that there is a problem that sound is absorbed.

(Modification 4) The transmission / reception mode of the signal Sfm90 between the tap shoe 10 and the tap sound generator 20 can be arbitrarily modified. In the above-described embodiment, a predetermined FM modulation and demodulation process is used, but the present invention is not limited to this form, and for example IrDA (Infrar
Infrared signals based on the ed Data Association standard may be transmitted and received. Further, the Blutoorh (registered trademark) standard may be used to perform piconet communication between the tap shoe 10 and the tap sound generation device 20. Alternatively, the tap shoes 10 and the tap sound generation device 20 may be connected by a predetermined cable to perform wired communication. In any case, tap shoes 10
If a predetermined agreement regarding data communication is established between the tap sound generation device 20 and the tap sound generation device 20, the same operation and effect as those of the above-described embodiment can be achieved. It is possible to generate a sound that makes use of the tap sound itself generated according to the movement of the (tap dancer) after adjusting it to a desired volume.

(Modification 5) The form of the tap sound generator 20 can be modified arbitrarily. Although not particularly limited in the above-described embodiment, it may be a piece of equipment such as a piece of equipment that is installed alone in a corner of a studio, or may be a type that is worn on a user's ear. Here, in the case of the type to be worn on the ear of the user U, as shown in the usage example in FIG. 8, if the sounding section 23 of the tap sound generation device 20 is made into a headphone shape, the user can tap You can practice tap dance while listening to the sound clearly. For example, in the case of practicing tap dance at midnight, and the user does not want to output the actual volume of the tap sound, but the user himself can be said to be particularly effective when he or she wants to hear the tap sound.

(Modification 6) In the tap shoe 10 according to the above-described embodiment, the microphones M1 and M2 and the transmitting portion D may be detachable striking units UN. By adopting such a striking unit UN form, the user can attach the striking unit UN to his or her familiar tap shoes as needed, and have the function as the tap shoe according to the present invention. . FIG. 9 is a striking unit UN according to the present modification,

N includes a belt unit BL1 on which the microphones M1 and M2 are installed and a belt unit BL2 on which the transmission unit D is installed. Of these, the belt portion BL1 has an engaging portion K1 that engages with the toe portion of the tap shoe TP and an engaging portion K2 that engages with the heel portion, and is a normal tap shoe TP that is almost fixed in shape. It can be easily attached to. Further, the other belt portions BL1 and BL2 are elastic belts of rubber material,
Even tap shoes TP having different shoe sizes can be easily attached and detached. FIG. 10 shows a diagram in which the striking unit UN according to this modification is attached to the tap shoe TP. Here, the microphone M1,
Although not shown, a cable for sending the electric signal collected by M2 to the transmission unit D is wired along the belt portions BL1 and BL2.

(Modification 7) Further, among the components of the tap shoe 10 according to the above-described embodiment, the chip C is used.
1, C2, the microphones M1, M2, and the transmission unit D may be detachable units. FIG. 11: is the figure which showed the external appearance of the hit | damage unit UN2 which concerns on this modification, and the normal shoe SH before attaching the hit | damage unit UN2. In FIG. 11, for convenience of explanation, shoes having only one foot are shown. As shown in FIG. 11, the impact unit UN2 according to the present modification includes a chip C
1, C2 and the belt portion BL3 on which the microphones M1 and M2 are installed, and the belt portion BL4 on which the transmission portion D is installed
It consists of Among these, the belt portion BL3 is provided with engaging portions K3 and K4 for adhering so as to wrap around the sole of the user's shoe SH, and the other portions of the belt portion BL3 and the belt portion BL4 can be expanded and contracted. The rubber material is used. As described above, the user can easily attach the striking unit UN2 to the shoe SH, so that the shoe SH that he / she is comfortable to wear can be used as the tap shoe 10 according to the present invention.
FIG. 12 shows a striking unit UN2 according to this modification,
It is the figure attached to the shoe SH. Here, although a cable for sending the electric signals collected by the microphones M1 and M2 to the transmission unit D is not shown, the belt unit BL
3 and BL4.

(Modification 8) Further, the tap sound generating system 100 according to the above-described embodiment is used in the tap shoes 10.
The tap sound generator 20 is attached to the tap shoe 10 itself.
The function related to 0 may be installed. Figure 13
It shows a tap shoe 10 'according to the present modification. As described above, the tap shoe 10 'includes the chips C1 and C2, the microphones M1 and M2, and the sounding unit P.
Equipped with K. The sounding unit PK has a function of converting the electric signals collected by the microphones M1 and M2 into mechanical vibrations and outputting (sounding) to the outside. FIG. 14 is a block diagram showing the flow of signal processing in the tap shoe 10 '. As described above, the chip sounds generated in the chips C1 and C2 are mainly generated by the microphones M1 and M2.
Is absorbed by each of. The electric signal absorbed by the microphones M1 and M2 is output by the sounding unit P.
Output to K. In the sounding section PK, the same signal processing as in the sounding section 23 of the tap sound generation device 20 according to the above-described embodiment is performed. That is, the microphones M1 and M2
The electric signal supplied from each of the
After the addition processing in K1, the amplification processing is performed in the amplification section PK2 with a predetermined amplification factor.

As described above, the tap shoe 10 ′ according to the present embodiment is similar to the tap shoe 10 according to the above-described embodiment in the case where the volume of the tap sound generated according to the movement of the foot of the user is lower than the desired volume. Even if there is, the sound can be emitted after the amplification processing of the volume level is performed. Since the sound emission processing is based on the tap sound itself generated by the actual foot movement of the user, it is possible to perform the sound emission processing that also reflects the expression of the tap sound due to the subtle foot movement of the user. . Furthermore, according to this modification, the tap shoe 10
Since ′ itself has the sounding unit PK, a function (transmitting unit D) for transmitting a signal to another device (tap sound generating device 20) is provided as in the tap sound generating system according to the above-described embodiment. It can be said that there is an advantage that it is not necessary to provide it.

(Modification 9) The present invention may be applied to other than the tap shoes. For example, in Figure 1.
As shown in FIG. 5, a single holder (herein, referred to as a cap) CAP1 to C attached to the fingertips of the user's hand.
The present invention can also be applied to AP5. In this modification, as shown in FIG. 15, the tips C61 to C are attached to the fingertips of the respective caps CAP1 to CAP5.
65 and microphones M61 to M65. Then, the user U who wears the caps CAP1 to CAP5 on each finger moves the fingers to make the chip C61.
When a chip sound is generated by hitting the floor surface with ~ C65, the chip sound is absorbed by the microphones M61 to M65 and converted into an electric signal. This electric signal is wirelessly output via the transmission unit 60 mounted on the arm of the user U. In this modification, the caps CAP1 to CAP5 themselves are physically separated, but satisfy the relationship of a series of cohesive aggregates that move with the movement of the user's hand. It is expressed as one holding unit.

FIG. 16 is a circuit block diagram according to the present modification. As described above, the caps CAP1 to CAP5 attached to the fingers of the user U are generated by the operation of the user U. Electrical signal S6 representing chip sound
1 to S65 are output respectively. Then, the transmitter D6
At 0, the composite signal of the electric signals S61 to S65 is output as the radio signal S60. This radio signal S
If a predetermined amplification process or the like is performed after receiving 60, the chip sound generated by the operation of the user U can be emitted even in this modification. Here, the microphones M61 to
The M65 is installed in the vicinity of the chips C61 to C65 and interlocks with the movement of the hand of the user U, so that there is no problem that the volume of the chip sound absorbed by the microphones M61 to M65 varies. . That is, it is possible to perform sound emission processing based on the tap sound actually generated when the user U's hand is moved, and it is also possible to represent the tap sound generated by the subtle hand movement of the user U. In this modification, an example is shown in which the caps CAP1 to CAP5 are attached to each finger of one hand of the user U, but the present invention is not limited to this, and it may be attached to both hands of the user, and is attached only to a predetermined finger. You may do it. Further, the vibration pickup described above may be used instead of the microphones M61 to M65.
