Abstract

An electro-mechanical transducer, which provides radial amplified multiple piston motion is formed from attached multiple lever arms and multiple electro-mechanical drivers. The piston motion is amplified by lever arms, which are attached to electro-mechanical drivers, such as piezoelectric or magnetostrictive drivers, which oscillate in a radial direction in unison with the applied voltage. A minimum of three pistons, three lever arms (or shells) and three drivers may be used. A preferred embodiment, uses four pistons, four lever arms (or shells) and four drivers. As a result of both the magnified motion of the lever arms (or shells) and the large acoustic radiating area of the multiple pistons, the transducer provides a means for a high-source level from a compact low-frequency broadband transducer.
