ABSTRACT:
An electronic drum includes a relatively hard surface layer, a relatively hard base layer, a relatively hard coupling portion, and a detection element. The base layer is spaced apart from the surface layer by a predetermined distance. The coupling portion couples the surface layer to the base layer. The detection element is mounted on the base layer to detect striking of the surface layer. The surface layer and the coupling portion are nonfoamed layers. The base layer is a combination of a nonfoamed or foamed layer and a support plate. A foamed layer is inserted as an impact absorbing layer between the surface and base layers.
