ABSTRACT:
The controllable implosive sound projector is comprised of a geometrically shaped cavity within a housing with a material across the face of the cavity. The air within the cavity is evacuated so as to form a vacuum causing a pressure differential to be formed across the material when the projector is submerged in a fluid. At a predetermined pressure differential the material is ruptured creating a shock wave at the face of the cavity which propagates into the cavity with a concave wave front deformation due to the confined boundaries of the cavity that forms a spherical shock wave at the interior of the cavity. At the focal point of the cavity, the spherical shock wave collapses and an impulse wave is generated that causes a pressure wave to radiate out from the opening into the fluid.
