ABSTRACT:
In a preferred embodiment, an inter-element mounting for ceramic elements in a piezoelectric transducer stack, which mounting includes two metal plates disposed between adjacent surfaces of the ceramic elements. The metal plates are cantilevered with respect to the surfaces of the ceramic elements, such that a substantial portion of the areas of the plates between the adjacent surfaces is unsupported and, therefore, the plates have a high degree of resilience. This structure provides controlled vibrational characteristics, structural integrity for high hydrostatic pressure, versatility in design for spurious resonance suppression or elimination, dampening, and special utility for pressure gradient hydrophone stacks.
