Abstract
A technique is described for eliminating the bandwidth degradation usually associated with piezoelectric cylindrical radiators that have been liquid filled for hydrostatic-pressure compensation. This technique utilizes an acoustically stiff internal structure to control the impedance presented to the vibrator at the internal ceramic-liquid interface. By controlling this interface impedance, it is possible to eliminate the effective mass contribution from the pressure compensating fluid. A comparison between theoretical and experimental data is presented for several units utilizing this technique. One of the units discussed is a cylindrical line transducer resonant at 2.5 kc/sec with a bandwidth greater than 1600 cps and an efficiency greater than 60%. The unit is pressure-compensated for deep-submergence operation with no degradation in performance.
