This percussion instrument has a speaker 3 facing outward at the other end, an amplifier 4 and a power supply circuit 5 inside the body 1, and a vibration sensor 6 of the sheet 2 inside the body 1. It is something.

等の調節器である。 As shown in the figure, the body 1 can be of various types, such as Japanese style, Western style, Taiko drum, drum, etc., and the beating sheet 2 is generally made of leather. As shown in the figure, one speaker 3 having a diameter equal to the diameter of one end of the body 1 is used, but a plurality of speakers 3 having a smaller diameter may also be used. An amplifier 4 (amplifier fire) and a power supply circuit 5 are provided inside the shell 1, and the power supply can be built into the shell 1 or introduced from outside via an outlet 9. As shown in FIG. 1, the vibration sensor 6 is provided with a protrusion 10 in the center of the seat 2, and has a switch 7 that is pushed by the reciprocating vibrations of the protrusion 10 to open and close every vibration cycle. After the detection signal generated by the closed circuit is amplified by the amplifier 4, the amplifier 4 causes the speaker 3 to sound. This switch 7 may be a non-contact switch (such as a reed switch) that causes the protrusion 10 to approach and separate. component control (by the filter built into the amplifier 4) etc. are adjusted and changed, and the speaker 3 is made to sound. In addition, as shown in Fig. 2, the microphone 8 itself is connected to the vibration sensor 6.
The amplifier 4 can be used to adjust the volume and timbre of the sound and make the speaker 3 vibrate. Note that the reference numeral 11 in the figure is an adjuster for adjusting the volume, tone color, etc. of the sound.

従つて電源スイツチを閉路し、上記一端叩打シ
ート２をばちで叩打すると上記センサー６によつ
て増幅器４およびスピーカー３が動作し、同増幅
器４を調節することによつてスピーカー３の音の
大きさおよび音色を調節し、調節音と上記叩打シ
ート２の叩打音とを混成させることができる。 Therefore, when the power switch is closed and the one end of the hitting sheet 2 is hit with a stick, the amplifier 4 and the speaker 3 are activated by the sensor 6, and by adjusting the amplifier 4, the loudness of the speaker 3 can be adjusted. By adjusting the sound and tone, it is possible to mix the adjustment sound with the tapping sound of the hitting sheet 2.

従来、太鼓、鼓等の打楽器では胴の一端面を叩
打すると他端面も振動して叩打音を発生し、音の
大きさは叩打の強弱によつて調節し得るが限度が
ある。又音色の調節は極めて困難であつた。 Conventionally, in percussion instruments such as drums and drums, when one end of the body is struck, the other end also vibrates to produce a striking sound, and the loudness of the sound can be adjusted by adjusting the strength of the strike, but there is a limit. Also, it was extremely difficult to adjust the tone.

本案は上述のように構成したので胴１の内部の
上記増幅器４によつて胴１の他端における音の大
きさおよび音色を調節し得るばかりでなく一端の

る。 Since the present invention is constructed as described above, not only can the loudness and tone of the sound at the other end of the drum 1 be adjusted by the amplifier 4 inside the drum 1, but also the sound can be mixed with the tapping sound of the hitting sheet 2 at one end. A sound is obtained, and striking sounds of different loudnesses and different tones are obtained from both end faces of a single percussion instrument such as a drum.
