ABSTRACT:
An electronic drum has cylindrical non-planar playing surface, and a force sensing detection unit is attached to the playing surface. The force sensing detection unit converts external striking forces applied to the playing surface into electrical output pulses. The electronic drum is attached to a mount shaft assembly with a resilient portion interposed between the electronic drum and the mount shaft. The mount shaft assembly enables the electronic drum to be mounted onto various support stands.
