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.

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.

An electronic drum comprising: a surface layer having a predetermined hardness for generating a vibration by a performer\s strike thereto; a base layer having a predetermined hardness formed to be spaced apart from said surface layer by a predetermined distance; a coupling portion having a predetermined hardness for transmitting said vibration to said base layer so that said base layer is vibrated by said performer\s strike; an impact absorbing layer which fills the space defined by said surface layer, said coupling portion and said base layer for absorbing an impact of said performer\s strike; and a detection element mounted under said base layer for detecting the transmitted vibration via said coupling portion and for generating a detection signal responsive to said transmitted vibration so that said detection signal is responsive to said performer\s strike.
