Title: Acoustic improvement device for wind instrument
Inventor: SUENAGA YASUO
IPC: G10D7/06
Filed: 2019-08-11
Abstract: To provide an acoustic improvement device which can improve vibration efficiency of a reed, create a sound which has a favorable effect on an instrument body, and adjust playing sound quality to suit a taste of a performer.SOLUTION: Provided is a device which is detachably attached to a mouthpiece in a wind instrument having the mouthpiece, a reed, and a ligature. The device is a plate-shaped weight, and with the reed attached to the mouthpiece, one end of the plate-shaped weight is attached to the mouthpiece via the ligature or a fastener on an outer surface opposite to a mounting surface of the reed, or on the opposite surface of the mounting surface of the reed across the mouthpiece, and vibration of the mouthpiece is attenuated by transmitting to the other end of the plate. The reed vibration is transmitted to the mouthpiece and resonates to vibrate during blowing. However, because the reed vibration and the resonance vibration of the mouthpiece interfere and overlap and the amplitude waveform is distorted, the resonance vibration of the mouthpiece is attenuated and suppressed, so that both vibrations do not interfere and overlap. As a result, reed vibration efficiency is improved, consequently a sound volume is also increased.SELECTED DRAWING: Figure 1
