are provided near both sides of the tone plate 7, and pass through the buffer material 9 to form the storage holes 13, 1 of the spacer 8.
It's now within 4. A first pressure sensitive contact 15 and a second pressure sensitive contact 16 provided on the printed circuit board 10 are arranged in the storage holes 13 and 14, respectively. Each of the pressure sensitive contacts 15 and 16 is a short stroke or non-stroke contact,
They are capable of reading minute changes, and are provided corresponding to each tone plate 7 arranged in large numbers. Among these pressure sensitive contacts 15, 16,
The first pressure sensitive contact 15 is pressed by the pressing projection 11 when the tone plate 7 in the vicinity corresponding to the pressing projection 11 is struck by the drumstick 2, and outputs an electric signal. The pressure-sensitive contact 16 is pressed by the pressing projection 12 and outputs an electric signal when the tone plate 7 in the vicinity corresponding to the pressing projection 12 is struck.

FIG. 3 shows the circuit configuration of the electronic percussion instrument. That is, the electrical signals output from the first pressure-sensitive contacts 15 are input to the first contact input section 17, and the electrical signals output from the second pressure-sensitive contacts 16 are input to the second contact input section 17. It is designed to be input to the input section 18. The first contact input section 17 outputs a key code signal to the musical tone creation section 19 via the bus line 17a in accordance with the input electric signal,
The musical tone creating section 19 receives the above-mentioned key code signal and the tone designation signal given via the bus line 20 from the sweet group 6 mentioned above, creates a musical tone based on these signals, and sends the musical tone signal to the amplifier section 21. It is output via line 19a. Further, a musical tone signal is supplied to the amplifier section 21 via a line 19a, and a volume control signal outputted from the first contact input section 17 via a line 17b is inputted, and the musical tone signal is appropriately amplified. The signal is output to the mixing section 22.

On the other hand, the second contact input section 18 outputs the key code signal to the musical tone generating section 23 via the bus line 18a, as described above, and the musical tone generating section 23 outputs the key code signal via the bus line 24. A musical tone is created using these signals and outputs the musical tone signal to the amplifier section 25 via the line 23a.The amplifier section 25 further receives the above musical tone signal and the tone signal via the line 18b. A volume control signal from the second contact input section 18 is input thereto, and the musical tone signal is amplified by an appropriate amount and output to the mixing section 22.

When the amplified signals from the amplifiers 21 and 25 are inputted via the lines 21a and 25a, the mixing section 22 mixes them and outputs a mixed signal to the line 22.

Each timbre designation signal is input to 9 and 23.

In this state, move each tone plate 7 of the tone plate section 3 to the drumstick 2.
When struck, the struck tone plate 7 vibrates up and down through the buffer material 9, and the sound produced when struck is muffled by the buffer material 9. In addition, the pressing protrusions 11 and 12 near the hit location press the pressure sensitive contacts 15 and 16 in response to the vibration of the tone plate 7. At this time, for example, if a location near the pressing protrusion 11 is hit,
Since the pressing protrusion 11 strongly presses the first pressure-sensitive contact 15, the pressure-sensitive contact 15 is connected to the first contact input section 1.
An electrical signal is output to 7. As a result, the key code signal is transmitted from the first contact input section 17 to the musical tone creation section 1.
9, the musical tone creating section 19 creates a musical tone based on the above-mentioned tone designation signal, and the musical tone is outputted to the amplifier section 21.
A musical tone signal is output to. Then, the musical tone signal is amplified by the amplifier section 21 according to the volume control signal from the first contact input section 17 (that is, a signal corresponding to the striking force of the drumstick 2), and is then amplified by the mixing section 22.
A musical tone is generated from the speaker section 4 via the amplifier section 26.

On the other hand, when a portion of the tone plate 7 near the pressing projection 12 is struck, the pressing projection 12 strongly presses the second pressure-sensitive contact 16, and the second contact input section 18
An electrical signal is output. In this case, the key code signal from the second contact input section 18 is sent to the musical tone creation section 23.
Here, a musical tone is created according to the tone designation signal, and after being amplified in the amplifier section 25 according to the volume control signal, it is sent to the speaker section 4 via the mixing section 22 and the amplifier section 26 in the same way as described above. is pronounced as a musical tone.

Further, for example, if the center of the tone plate 7 is hit, that is, each of the pressing protrusions 11 and 12 simultaneously hits each pressure-sensitive contact 1.
5, 16, each pressure sensitive contact 15,
16 to each contact input section 17, 18, and as in each case described above, after each musical tone is created in each musical tone creating section 19, 23, each amplifier 21 , 25, the volume is controlled and input to the mixing section 22. The mixing section 22 mixes the tones, and the mixed musical tones are output from the speaker section 4 via the amplifier section 26.

In this way, according to the electronic percussion instrument, even beginners can perform well without the need for any new playing techniques, and in addition, the chorus effect with multiple tones and the touch response effect due to the force of hitting with two drumsticks. It is also possible to perform a combination of In other words, if you hit the middle point between the first pressure sensitive contact 15 and the second pressure sensitive contact 16, a musical tone will be produced with a volume and tone that are inversely proportional to the distance from both contacts 15 and 16.

[Effect of idea]

As explained above, according to the electronic percussion instrument according to the invention, there are a large number of tone plates 7 that can vibrate as a whole according to a percussion operation, and
Each of the tone plates 7... is arranged at a lower position of the tone plate 7... and at a mutually different position, and each of the tone plates 7...
Since it is equipped with a plurality of impact detection elements (in the case of this embodiment, pressure sensitive contacts 15 and 16) that output mutually different tone designation signals in response to a impact operation on a single tone plate 7, the impact position with respect to one tone plate 7 can be adjusted. Depending on the impact, musical tones of a plurality of different tones can be generated simultaneously, or musical tones of one corresponding tone can be selectively generated for each hitting position. As a result, even if you are a beginner, you can change the tone by simply performing percussion operations while changing the percussion position without performing any advanced percussion performance operations. The sound of the performance
can be obtained easily and reliably.
