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

<Configuration of First Embodiment> FIG. 1 is a partially sectional perspective view showing a first embodiment of the present invention. In this drawing, the striking body side is exaggerated and drawn larger than the tone generator.

In FIG. 1, an insulative holding member 7 is fixed to the striking body 1 inside a striking body 1 which is an operation member which is rocked by a player. This insulating holding member 7
Is provided with a coil spring 10 which is a conductive member having a base end fixedly held by the holding member 7 and a free end protruding from the holding member 7 and having elasticity.

Around the coil spring 10, a plurality of contact members
8A and 8B are arranged at a predetermined interval from each other. The base ends of the plurality of contact members 8A and 8B are fixedly held by the holding member 7, and the free ends are the coil springs.
It is held with 10 free ends and a predetermined gap. The rod-shaped hitting body 1 that is hit or shaken during a performance is formed in substantially the same size and the same appearance as a conventional drum stick. The impacting body 1 is a cylindrical stick body 2
And a dome-shaped chip 3 fixed to the tip of the stick body 2 and a cap 4 screwed to the base end of the stick body 2. A mounting plate 6 fixed to a predetermined position by a positioning member 5 is disposed inside the stick body 2, and an insulating holding member 7 is fixed to an upper surface of the mounting plate 6. Two conductive contact members 8A and 8B are fixed to both side surfaces of the holding member 7 with screws 9 so as to face each other. In the through hole 7a formed in the center of the holding member 7,
Each of the contact members 8A and 8B vibrates when the impact body 1 is hit or the like.
A conductive coil spring 10 that is in electrical contact with either one of them is press-fitted and fixed. The coil spring 10 functions as a common contact member for the two contact members 8A and 8B, and accordingly, the coil switch 10 and one contact member 8A constitute a first switch portion 11A.
The coil switch 10 and the other contact member 8B constitute a second switch portion 11B. In order to ensure reliable and stable electrical contact between the free ends 10a of the coil springs 10 at the tips of the contact members 8A and 8B, substantially U-shaped contact pieces 8a are provided. , 8b are integrally formed (see FIG. 3). Further, the positioning member 5 and the chip 3
Between them, a rubber cushioning member 12 for effectively absorbing the rattling of the positioning member 5 is interposed.
Further, on the outer peripheral surface of the stick main body 2, at a position corresponding to each of the contact members 8A, 8B, a first switch portion 11A constituted by the contact members 8A, 8B and the coil spring 10 is provided.
And a tone name display section 13 for displaying tone names of different timbres generated based on the electric signal from the second switch section 11B. As a result, it is possible to visually confirm the name of a musical tone to be struck and sounded by striking the striking body 1.

On the other hand, one end of a connection cord 14 is connected to the two contact members 8A, 8B and the base ends 8c, 8d, 10b of the coil spring 10, and the other end of the connection cord 14 is It is connected to a musical sound generator 15 for producing a predetermined musical sound when hitting or rocking. This tone generator
15 can generate a predetermined musical tone based on the impact of the hitting body 1 or the like, and can also be performed by pressing a plurality of drum pads 16 provided at the upper part of the apparatus main body. As in the case of the keyboard musical instrument of the above, a predetermined musical tone can be produced by depressing each key provided on the keyboard section 17.

Next, a circuit configuration for generating a predetermined musical tone based on the impact of the impacting body 1 will be described with reference to FIG.

As shown in FIG.
Type flip-flop circuit (hereinafter referred to as "RSF / F") 1
The set input terminal S of the RSF / F18 is provided with a first switch portion composed of a coil spring 10 and one contact member 8A when the hitting body 1 is hit.
An electric signal generated based on the ON operation of 11A is input, and this RSF / F18 is set. The output terminal Q of the RSF / F18 has a chattering from the point of occurrence of the first key-on signal output from the output terminal Q based on the ON operation of the first switch portion 11A when the hitting body 1 is hit. A timer circuit 19 for measuring time (t) is connected, and a CPU (Central Processing Unit) 12 for controlling a tone generator 20 to emit a predetermined tone based on the key-on signal is connected. . From the output terminal of the timer circuit 19, in order to prevent the generation of unnecessary musical sounds generated by the chattering phenomenon accompanying the vibration of the coil spring 10 in the event of a single hit of the hitting body 1, 1
Is performed, a carry signal (reset signal) is output after a predetermined time, that is, a chattering time is measured, based on the first key-on signal generated at that time. This carry signal is input to the reset input terminal R of the RSF / F18, so that the RSF / F18 is in a reset state and can again receive the input of the first switch unit 11A. The timer circuit 19, as described above,
The chattering time (t) from the point of occurrence of the key-on signal generated based on the first strike of the striker 1 is counted. The time interval (t) is a predetermined preset sent from the CPU 21. It is set based on the time value data (p). This time interval (t) corresponds to the striking body 1
Is set in consideration of both the time interval required for continuous hits and the chattering time interval when the user repeatedly hits in a short time. That is, this time interval (t) is
If the setting is too long without considering the time interval required for continuous hitting, the setting state of the RSF / F18 set based on the first key-on signal accompanying the hitting of the hitting body 1 becomes longer by that amount. In addition, even if the second key-on signal is generated within a short time due to the chattering phenomenon, the second key-on signal can be prevented from being sent to the CPU 21. Although it is possible to reliably prevent the generation of a musical tone from the part 20 and it is convenient, the second continuous striking even when the striking body 1 is continuously struck twice or more at short intervals. As a result, a key-on signal may not be sent to the CPU 21 side, so that it is impossible to generate a predetermined musical sound from the musical sound generator 20 based on the key-on signal in response to continuous hits. Therefore, the time interval (t) of the time counting operation of the timer circuit 19 is set to a range not less than the time interval (t ₁ ) of the chattering and not more than the minimum time interval (t ₁ ) at the time of general continuous hitting.

Similarly, the above-mentioned RSF / F1
The same RSF / F22 and timer circuit 23 as those of the timer circuit 8 and the timer circuit 19 are provided. When the second switch 11B inside the impact body 1 is turned on and a predetermined electric signal is output from the switch section 11B. The RSF / F22 enters a set state, and a key-on signal is output from the RSF / F22 to the CPU 21 and the timer circuit 23. Accordingly, as described above, a predetermined musical tone is generated based on the key-on signal, as described later. When a sound is output from the system and a predetermined chattering time (t) elapses from the time when the key-on signal is generated from the timer circuit 23, a carry signal (reset signal) is generated.
It is input to the RSF / F22 and waits for the input of the next key-on signal. In this case, the timbre of the musical tone generated based on the key-on signal from the first switch unit 11A and the timbre of the musical tone generated based on the key-on signal from the second switch unit 11B are different from each other. Is set to In this embodiment, the CPU 21 has a switch 24 for variably controlling the time interval (t) of the time counting operation of the two timer circuits 19 and 23 at an arbitrary time interval by manual operation or stepping operation. Is provided.

The tone generator 20 described above uses a PCM (pulse code modulation) method and a PCM sound source ROM 25 that fixedly stores a plurality of sound source data such as predetermined percussion sounds and sampling sounds. An address control unit 26 for reading and controlling the sound source data stored in the PCM sound source ROM 25 in accordance with control data from the CPU 21 based on a key-on signal generated when the hitting body 1 is hit, and the like; And a sound system 27 for generating a corresponding predetermined musical tone based on the sound source data read from the PCM sound source ROM 25 in accordance with the control data from the unit 26.

<Operation of First Embodiment> Next, the operation of the electronic percussion instrument according to the first embodiment having the above-described configuration will be described.

First, prior to the start of the batting performance, a tone generator
By switching the tone color selection switch 28 provided in the unit 15, selection and designation are performed so as to obtain musical tones of mutually different tone colors (for example, bass drum and hi-hat).

Next, when the striking body 1 is struck with the upper curved surface in FIGS. 2 and 3 of the chip 3 as a striking surface, the coil spring 10 provided inside the striking body 1 is driven by an arrow a. Vibrating in the direction, the free end 10a of which
Make electrical contact with Then, along with the electrical contact, the first switch portion 11A constituted by the coil spring 10 and the one contact member 8A is turned on, and a predetermined electric signal is output from the first switch portion 11A. You. The electric signal output from the first switch section 11A is
The signal is input to a set input terminal S of one of the RSF / Fs 18 in the tone generator 15 via a connection cord 14 wired between the tone generator 15 and the tone generator 15, and the RSF / F 18 is set.
Accordingly, a key-on signal is output from the output terminal Q of the RSF / F 18 according to the set state, and the key-on signal is input to the timer circuit 19 and also to the CPU 21. Based on the key-on signal input to CPU 21, C
The PU 21 outputs musical tone control data to the address control unit 26. Therefore, the address control unit 26 outputs the address control data to the PCM sound source ROM 25, and according to the address control data, one sound source data stored in the PCM sound source ROM 25, that is, the sound source data of the bass drum sound. And the sound source data is input to the sound system 27. Accordingly, a bass drum sound is emitted from the speaker SP (see FIG. 1) constituting the acoustic system 27.

On the other hand, when a key-on signal based on the impact of the striker 1 is input to the timer circuit 19, a time corresponding to the preset time value set in advance based on the operation of the preset time value setting switch 24 is set in the timer circuit 19. 19 counts the time, and after that time counts the carry signal to RSF / F18
And the RSF / F18 is reset. By the way, at the time of a single impact or the like of the impacting body 1, the coil spring 10 chatters with one of the contact members 8A based on the impact force or the like, and they come into electrical contact with each other. A plurality of electric signals may be output from the switch 11A in a short time. However, even when such a situation occurs, the plurality of electric signals output until the timer circuit 19 outputs the carry signal and the RSF / F 18 is in the reset state are output from the RSF / F 18 by the key-on signal. Is not output as a result, it is possible to prevent the occurrence of unnecessary musical sounds accompanying the chattering of the first switch section 11A. After the reset state of the RSF / F18,
In the case where the second strike is performed successively after the first strike of the striker 1, the electric signal from the first switch unit 11A is set to the RSF / F18, whereby the key is turned on from the RSF / F18. Since a signal is output, a bass drum sound is emitted from the speaker SP of the audio system 27 based on the key-on signal, similarly to the above-described operation.

Next, contrary to the above-described case, when the hitting body 1 is hit with the curved surface on the lower side in FIGS. 2 and 3 as the hitting surface, the chip 3 is provided inside the hitting body 1. The coil spring 10 vibrates in the opposite direction (the direction of arrow b) from the above case, and its free end 10a electrically contacts the other contact member 8B. A second switch portion 11 comprising a spring 10
B turns on. As a result, as in the case described above, the second
The electric signal from the switch unit 11B is input to the RSF / F22, and is output from the RSF / F22 as a key-on signal to the CPU 21 and the timer circuit 23.Therefore, other signals stored in the PCM sound source ROM 25 based on the key-on signal are output. One of the sound source data, ie, the sound source data of the hi-hat sound, is read out, and accordingly, the speaker SP constituting the sound system 27 is read out.
, A hi-hat sound is emitted. After a lapse of a predetermined chattering time (t) from the time when the key-on signal is generated, a carry signal (reset signal) is output from the timer circuit 23, and the RSF / F22 is set to a reset state. Waiting for the input of the next switch signal is the same as in the case described above.

<Configuration and Operation of Second Embodiment> Next, FIG. 5 is a partially omitted exploded perspective view showing a second embodiment of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In this embodiment, unlike the case of the first embodiment,
By changing the striking position of the striking body 1, it is possible to selectively generate four tones of musical tones.

That is, in this embodiment, four conductive contact members 8C to 8F are fixed to the both side surfaces of the holding member 7 disposed inside the stick main body 2 with the screws 9 so as to face each other. ing. Also, at the center of the holding member 7,
The four contact members 8C vibrate when hitting the hit body 1 or the like.
To 8F, a conductive coil spring 10 that is electrically contacted is fixed. The coil spring 10 functions as a common contact member for the four contact members 8C to 8F, and the coil spring 10 and the four contact members 8C
To 8F, the first, second, third, and fourth switch sections 11
C to 11F are configured. As in the case of the first embodiment, the contact pieces 8c to 8F are provided at the tips of the four contact members 8C to 8F.
8f are integrally formed, and the four contact members 8C
On the outer peripheral surface of the stick main body 2 corresponding to .about.8F, a musical tone name display section 13 for displaying musical tones of four timbres is provided.

In such a configuration, when the hitting body 1 is hit while the hitting body 1 is rotated about its axial direction by about 90 degrees, the coil spring 10 Selectively contact each of the contact members 8C to 8F, and the first to fourth switch portions 11C to 11F formed by the contact members 8C to 8F and the coil spring 10 sequentially turn on to operate Since predetermined electrical signals are output from the switch units 11C to 11F, the corresponding RSF / F
(Not shown), so that four tone sounds can be selectively emitted from the sound system of the tone generator based on the key-on signal from the RSF / F. Therefore,
Compared to the case of the first embodiment described above, a greater number of tones can be produced by changing the hitting position of the hitting body 1, so that a more varied hitting performance can be achieved. Become.

<Structure and Operation of Third Embodiment> FIG. 6 is a sectional view showing a third embodiment of the present invention.

This embodiment shows a configuration example in which the occurrence of a chattering phenomenon accompanying the bouncing of the coil spring 10 when the hitting body 1 is hit hard can be reliably prevented.

That is, in this embodiment, the two contact members 8G are set within an angular range of about 180 degrees around the arrangement position of the conductive coil spring 10 arranged inside the cylindrical stick 2. , 8H, and these contact members 8G,
An insulating member 29 made of a material such as rubber or plastic is provided at a position facing 8H. Note that a buffer member 30 is interposed between the insulating member 29 and the stick main body 2.

In the case of such a configuration, the striking body 1 is strongly struck and the coil spring 10 is brought into electrical contact with the one contact member 8G or the other contact member 8H. (The arrow c in FIG. 5)
Or d direction), the insulating member 29 is provided on the bound side even if the coil spring 10 bounces,
The contact of the coil spring 10 with the contact members 8G and 8H for which electrical contact is not desired can be reliably prevented. Therefore, generation of unnecessary musical sounds due to chattering of the coil spring 10 can be prevented. Further, in the case of such a configuration, since chattering of the coil spring 10 can be reliably prevented, an electronic circuit for preventing chattering such as an RSF / F and a timer circuit as shown in FIG. 4 is omitted. Therefore, the circuit configuration can be simplified accordingly.

<Modifications> In each of the embodiments described above, a case is described in which each switch section is turned on by a vibration generated when a striker is hit to generate a musical tone having a different predetermined tone. The present invention is not limited to this, and when the impacting body is shaken at a predetermined speed, it is possible to obtain the same operation and effect as in the above-described embodiments. In each of the above embodiments, the case where a coil spring is used as an example of the conductive member is described. However, the present invention is not limited to this example, and a long conductive wire may be used. In the above embodiment, the case where two tone colors can be selected (FIGS. 1 to 3 and FIG.
The case of the embodiment shown in the figure) and the case of selecting four tone sounds (the case of the embodiment shown in FIG. 4) are described. However, the present invention is not limited to this, and the number of contact members may be increased or decreased. Thus, it may be possible to generate three tones, five or more tones. Further, in the above embodiment, only on the basis of the key-on signal generated at the time of the first hit of the hit body, etc.,
The case where a predetermined tone is generated has been described. However, the present invention is not limited to this example. An electric signal generated by chattering due to the vibration (bound) of the coil spring is directly picked up as a key-on signal, and the key-on signal is generated. A predetermined tone may be generated based on the tone. With this configuration, a plurality of musical tones can be continuously obtained based on a single hit of the percussion body, and a percussion instrument performance with further changes can be performed. Furthermore, in this embodiment, a connection cord for supplying an electric signal from each switch section to the tone generator is wired between the hitting body and the tone generator.
In order to increase operability, a wireless system may be employed in which a hitting body is provided with a transmitting unit for transmitting, for example, an FM radio wave, and a musical sound generating device is provided with a receiving unit for receiving the radio wave.

〔The invention's effect〕

As is apparent from the above description, according to the present invention, when the player shakes the operation member, the operation member is rocked at a predetermined level or more, and is provided at a position corresponding to the direction of the rocking force. When the contact member and the conductive member are in an electrically conductive state, an instruction is given to generate a tone having the characteristic assigned to the contact member in the conductive state, so that the swing of the operating member can be prevented. By appropriately selecting the direction, a tone characteristic corresponding to the direction can be selectively indicated.

For this reason, it is possible to perform an extremely simple operation without performing a complicated operation such as switching a tone characteristic changeover switch.
There is an excellent effect that a musical sound characteristic can be selected and a performance with musical sounds having various characteristics can be performed.
