Abstract:
1. A percussion detecting apparatus comprising: a percussion surface part formed of an air-permeable material and having a light transmitting property, said percussion surface part including a percussion surface; a support part that supports said percussion surface part; a detecting device that detects a beat applied to said percussion surface of said percussion surface part and outputs a beat signal indicative of the sensed beat; and a percussion pattern indicating device that performs visual indication corresponding to a percussion pattern of the beat applied to said percussion surface, at least through said percussion surface, based on the beat signal output from said detecting device, wherein said percussion pattern indicating device includes a light radiating part that is resilient and radiates light, said light radiating part is disposed on an opposite side from said percussion surface of said percussion surface part such that said light radiating part is visible through said percussion surface part from a side toward said percussion surface, and when said percussion surface of said percussion surface part is beaten, said light radiating part is pressed by said percussion surface part and is resiliently deformed, thereby applying a reaction force to said percussion surface part and changing a pattern of light radiation by said light radiating part, whereby visual indication corresponding to the percussion pattern is performed.
