Abstract : The patent describes a transducer for use underwater and capable of surviving high shock forces often sustained by ships, submarines, and unretarded air delivery weapons. A ring-shaped piezoelectric ceramic active element is tightly wound with fiberglass and potted to obtain compressive hoop stresses on the ceramic and mounted in axial compression on a transducer base for attachment to a vehicle.
