Abstract

A transducer includes a resonator assembly having a first surface and a second surface on opposite sides thereof, a front mass having a surface adjacent to the first surface of the resonator assembly, a back mass having a surface adjacent to the second surface of the resonator assembly, and a compression assembly mounted on the front mass and the back mass. The compression assembly is adapted to effect compression across the resonator assembly. The resonator assembly contains at least two driven active elements such that when at least one of the driven active elements is driven to increase in thickness, at least one of the other driven active elements is driven to decrease in thickness.
