Percussion instrument apparatus, system and process
A percussion instrument that suppresses erroneous detection by a rim sensor includes a first plate affixed to a frame, a second plate elastically supported on the first plate by one or more elastic members, and a rim sensor attached to the second plate. Large vibrations of the frame from an impact of a strike on the rim are transmitted to the second plate, and the rim sensor provides an output corresponding to the striking force. Also, vibrations of the frame generated by striking sound or external sound is attenuated by the elastic member, to suppress transmission of such vibrations to the second plate.
