ABSTRACT:
A percussion instrument transducer for converting a striking impact into a representative electrical impulse triggering signal. The transducer is formed of a piezoelectric member of disc shape secured to an electrically conductive disc. The piezoelectric member and disc are supported in a housing on a support platform of smaller diameter than the diameter of the disc so that the periphery of the disc is cantilevered beyond the support platform to provide enhanced piezoelectric impulse action.
