ABSTRACT:
An underwater sound generator having a planar piston which is repelled by energizing a coil, to create a pressure pulse. The pressure at the rear face of the piston is made to track the pressure at the piston front face by providing a rear compressible air volume which is connected by a bleed aperture to the non-compressible air volume at the rear face of the piston. The compressible volume is defined by a diaphragm extending across a fillet having a shallow spherically concave rear surface. As the depth of the generator increases, the diaphragm moves towards the fillet, compressing the air and effectively equalizing the pressure across the piston. In the limit the diaphragm is pressed against the fillet, with a minimum of tension, reducing the compressible volume to a minimum.
