Abstract
An electronic percussion instrument includes a head, a frame, and an impact sensor, and an air ventilation mechanism which includes a pair of cutouts which are distanced from each other and formed in the periphery of the head. The head is attached to the frame such that the periphery of the frame is externally enclosed with the periphery of the head precluding a pair of cutouts. Additionally, a pair of connecting parts with reduced thickness is linearly elongated across the back of the head in parallel. When the head is struck with a beater, a vibration is caused to occur in the head and detected by the impact sensor to produce an electric signal which is used to generate an electronic musical sound, wherein the air ventilation mechanism releases air from the back of the head so as to reliably secure noiselessness while reducing noise.
