Abstract

By utilizing the concepts of the radiation resistance and radiation quality of harmonic vibration, both the effective force of surrounding coupling fluid on a thin spherical shell transducer during excitation by a driving-voltage signal and its transient response function can be determined by developing an equivalent circuit. The transducer acts like an electrical-acoustic filter. The properties of both driving-voltage signal and the transducer determine that of the radiated acoustic signal.
