ABSTRACT:
A high gain acoustic transducer is formed of a voice coil and a magnetic material housed within a transducer housing. The transducer housing includes two symmetrical dome halves formed of a flexible material. Vibrations of the transducer induce a current in the voice coil as the magnetic material is caused to translate relative to the voice coil. Alternatively, electrical signals applied to the voice coil induce vibrations in the transducer. The voice coil is supported by a first of the two dome halves by way of a first support assembly, and the magnetic material is supported by a second of the two dome halves by way of a second support assembly. The first and second support assemblies are positioned against similarly-dimensioned portions of the first and second dome halves, respectively. Resonating surfaces of the two dome halves are of substantially similar dimensions. The housing forms a watertight enclosure, and the transducer may be utilized in underwater applications.
