Abstract: An electronic percussion instrument for suppressing sound source noise is described. The instrument includes a percussion pad, a metal plate disposed below the percussion pad, at least one damping element disposed in a ring-like manner below the metal plate, a resonance conductive member disposed below the damping element, a sensor disposed at a central region below the resonance conductive member, and a noise suppressing mechanism disposed at a peripheral annular region below the resonance conductive member. The noise suppressing mechanism includes, in an order from top to bottom, a foam ring and a metal ring. The metal ring has a plurality of cushioning elements thereon. Accordingly, the instrument can effectively suppress or otherwise eliminate interference on and noise sensed by the sensor caused by vibration of a casing when the percussion pad is percussed. This can greatly improve the sound effect and performance of the instrument.
