ABSTRACT:
A flextensional transducer provides a low resonance frequency by having its shell portions connected to its ends by a pin- or rotation-type hinge whereby the motion of the ends of the transducer caused by energization of the transducer drive is transferred to the shell portions by the hinge. The reduction in the resonance frequency is achieved by the shell portions acting as a hinged plate whose ends rotate relative to the transducer ends rather than being cantilevered as in the prior art.
