Abstract
An electronic percussion instrument has a body with a hitting surface that a player can hit. Piezoelectric elements are mounted on respective mounting surfaces Sa formed in the body and are configured to convert vibration generated by a hit on the hitting surface to an electrical signal. The signals have higher output characteristics in vibration in a direction perpendicular to the mounting surfaces than in vibration in a direction parallel to the mounting surfaces. The electronic percussion instrument outputs the electrical signal generated by the piezoelectric elements. The mounting surfaces are inclined from a horizontal plane to a vertical direction β toward a center of the body. The piezoelectric elements are mounted on a concentric circle at regular intervals about a central axis of the body.
