Abstract
An audio reverberator system having a piezoelectric transducer filter circuit for outputting selected audio vibrational frequencies having selected amplitudes responsive to inputs from an amplifier. The audio reverberator system includes a piezoelectric transducer having an intrinsic capacitance coupled to an additional circuit element to form a low-pass type filter circuit for attenuating higher frequency inputs to the transducer to provide a desired flat frequency response for an audio vibrational output to vibrate a reverberation plate for production of a desired audio output.
