Abstract
A sensor for sensing vibrations in a transducer assembly and for generating an electrical signal indicative of the vibrations is disclosed. The sensor includes a piezoelectric generator which is mounted with a bimorph on a common substrate. The piezoelectric generator and bimorph have a common cantilevered end portion and an opposed deflectable free end portion so that deflection of the free end portion of the bimorph causes a corresponding deflection of the free end portion of the piezoelectric generator, whereby the piezoelectric generator generates an electrical indication of the instantaneous degree of deflection of the bimorph.
