Patent ID: 7029452

Claim:
A hydrotherapy system, comprising: a rigid tank filled with a liquid, said rigid tank having interior walls and exterior walls; at least one acoustic driver, each said acoustic driver coupled to one of said exterior walls via a sealed air-filled chamber that includes said one of said exterior walls; and controllable signal source means coupled to each said acoustic driver for generating and applying a drive signal thereto, wherein each said acoustic driver generates an acoustic wave in said chamber associated therewith, said acoustic wave impinging on said one of said exterior walls wherein said acoustic wave is coupled to said liquid for transmission therethrough, said acoustic wave interacting in said liquid with at least one of (i) a reflection of said acoustic wave from one of said interior walls, and (ii) at least one other acoustic wave generated by another of said at least one acoustic driver for impingement on another of said exterior walls and subsequent transmission through said liquid.
