VOLUMETRIC DISPLACEMENT TRANSDUCER FOR AN UNDERWATER ACOUSTIC SOURCE

摘要

A volumetric displacement transducer is provided for generating acoustic signals. The transducer housing incorporates at least one pair of opposed plates mounted for radial vibration. A driving mechanism is coupled to the opposed plates for driving the plates simultaneously in opposition to each other at a desired frequency, whereby an acoustic signal is radiated into a medium, such as water, surrounding the housing.
