ELECTRONIC PERCUSSION INSTRUMENT

摘要

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.

主权项

1. An electronic percussion instrument comprising:
a frame having a head-attaching portion; a head, which is made of an elastic material with a higher flexibility than the frame, which includes a main strike area which is disposed on a surface and mainly subjected to a striking operation, and whose periphery is directly fixed to the head-attaching portion of the frame or whose periphery is fixed to the head-attaching portion of the frame via a joint member; and an impact sensor which converts a vibration occurring on the main strike area subjected to a striking operation into an electric signal, wherein an opening which allows air to transmit there through at the striking operation is formed in a portion of the head circumventing the main strike area.
