ELECTROACOUSTIC TRANSDUCER WITH IMPROVED SHOCK RESISTANCE

摘要

An electromechanical transducer assembly comprises a stacked group of axially aligned piezoelectric ceramic rings. Plates, which have a larger diameter than the ceramic rings, are positioned between each of the adjoining faces of the ceramic rings. Therefore, the edges of the plates extend outwardly beyond the periphery of the ceramic rings. A tape or filament is tightly wound about the rim of each ceramic ring to maintain a radial stress upon the ceramic elements.
