ABSTRACT:
Disclosed is a sound source which will broadcast predetermined frequency ustical energy throughout subaqueous environmental mediums. It includes a housing body of cylindrical configuration with elongated slots located at uniform distances around the periphery thereof. A flexible, resilient sleeve surrounds said housing in such manner that it forms a movable diaphragm over each of said slots. By means of a pressure control system, internal gas pressure within said housing body may be regulated to make it less than the pressure of the subaqueous medium external thereto, thereby pulling said diaphragm inwardly through said slots. A plurality of motor driven rollers roll around the inside surface of said housing and contact the inside surface of said flexible sleeve, thereby pushing it in an outwardly direction back through said slots, so as to displace some of the subaqueous medium adjacent thereto. The movement of said diaphragms thus effects the generation of acoustical energy which is transmitted radially therefrom throughout said subaqueous medium.
