An underwater acoustic transducer for providing high amplitude low frequency acoustic output wherein a plurality of flextensional transducer ovals are formed into a mechanical transformer ring with a corresponding plurality of transducer drivers received therein. A corresponding plurality of radiating surface plates are fixed to the flextensional transducer ovals so as to form a flextensional ring which has disposed on both ends thereof an end plate. Furthermore, a sealing boot is disposed around the flextensional ring which receives the necessary power to operate the transducer drivers so as to vibrate the flextensional transducer ovals to provide the desired motion. Additionally, the flextensional rings can be configured into a tube so as to provide increased levels of acoustic energy.

Low frequency underwater acoustic transducer

This invention provides an apparatus including a plurality of omnidirectional hydrophone sensors in a particularly configured array comprised of ring members which are carried between a plurality of tensioned cables, the cables being tensioned by an anchor weight at the bottom end of the array and a capsule float at the top end, the configuration enabling simplified signal processing techniques to achieve sound source discrimination in both azimuth and elevation within an underwater environment.
