Abstract
An electronic percussion instrument includes a head, a frame, and an impact sensor. The back of the head is divided into a main area (e.g. a main strike area) and an auxiliary area. At least one connecting part is arranged above or below the main area in the back of the head and reduced in thickness compared to the auxiliary area, thus reducing vibration from being transmitted through the head. The impact sensor is attached to the back of the main strike area of the head via a cushion member. When the main strike area of the head is being 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 while suppressing mechanical noise due to an impact between the beater and the head.
