ABSTRACT:
A substantially flat and disc-like shaped sound transducer for sensing sound waves in a fluid transmission medium and having directional and omnidirectional response characteristics to the sound waves. The sound transducer having a circular vibratile plate divided into quadrantal portions and having a surface adapted to be coupled to the transmission medium for providing sound wave motion in the portions dependent upon, and in response to, sound wave travel in the transmission medium and having a plurality of electroacoustic transducer elements coupled to the quadrantal portions of the vibratile plate for providing electrical output signals in response to the wave motions in diametrically opposed quadrantal portions. The sound transducer responding to incident sound waves having wavefront travel directions, in the transmission medium, substantially parallel to the coupled surface. The relatively flat physical configuration of the sound transducer makes it especially suited for flush mounting in a surrounding surface, such as the hull of a ship or submarine.
