Abstract: An electronic percussion instrument includes a head, a frame, and an impact sensor, and a plate serving as a vibration-damping member.

Abstract: An electronic percussion instrument includes a stand, a support member (e.g. a stay), a pad member with a head, and an impact sensor. The support member has an L-shape including a stand-attaching portion and a pad-attaching portion. The stand-attaching portion is fixed to the stand while the pad-attaching portion is extended vertically from the front end of the stand-attaching portion at an inflection point. Owing to the elasticity of the support member, the pad-attaching portion is deflected about the inflection point in the rearward direction in comparison with the stand-attaching portion due to a striking force applied to the head being struck with a beater. Upon detecting an impact applied to the head, the impact sensor generates an electric signal so as to generate a musical sound. Thus, it is possible to suppress floor reverberation by absorbing an impact between the head and the beater via the support member.
