Abstract : The patent relates to the novel construction of a single- or a multiple-element underwater sound transducer comprising one or more cylindrical, capped, piezoelectric ceramic elements (barium titanate, lead zirconate-titanate, or other material of similar properties) in a linear configuration. The structure results in acoustically decoupling each element from adjacent elements and from all of the supporting structure while retaining acoustic stability of the transducer over the broadest possible frequency range and with wide variation in temperature and hydrostatic pressure.
