ABSTRACT:
According to this invention, an electronic drum has a head portion. An annular frame is arranged to generally surround the head portion. A vibration plate is arranged to be in tight contact with a lower surface of the head portion, and vibrates in response to the performer's strike of the head portion. A pickup device is mounted on the vibration plate so as to detect the vibration of the vibration plate. A vibration preventing portion is inserted between the head portion and the annular frame so as to prevent the vibration from being transmitted to the annular frame. The head portion and the vibration preventing portion are integrally formed of a flexible material. A sound device is connected to the pickup device so as to produce a drum sound in response to the detected vibration.
