ABSTRACT:
Membranes for use with capacitive electric musical instrument vibration transducers comprise an acoustically vibrating surface, a vibrating variable capacitor plate made from an electrically conductive material, and means of electrically connecting said vibrating variable capacitor plate to the electric circuitry of a capacitive electric musical instrument vibration transducer. These membranes can be used as drumheads, banjo membranes, and other stretched vibrating surfaces on similar musical instruments. In addition to generating the sound associated with these instruments, these membranes help capacitive electric musical instrument vibration transducers generate a signal describing the emitted sound of the musical instruments they are attached to.
