Abstract : The patent application describes a high power density, low frequency superconducting transducer which includes an electro-dynamic drive wherein a superconducting magnet provides the primary driving force for two AC-driven copper coils. Each of the copper coils is rigidly attached to a corresponding movable piston. Each of the pistons radiates acoustic energy as it is energized by the corresponding copper coil. The transducer provides a very powerful light weight underwater acoustic source despite the additional refrigeration requirements for the superconducting magnet used.
