Patent ID: 7122943

Claim:
A cavitation system, comprising: a cavitation chamber, wherein at least one wall of said cavitation chamber comprises a flat external surface; an acoustic driver assembly coupled to said cavitation chamber, comprising: at least one piezo-electric transducer; a tail mass adjacent to a first side of said at least one piezo-electric transducer; a head mass with a first end surface and a second end surface, wherein said first end surface of said head mass is adjacent to a second side of said at least one piezo-electric transducer and said second end surface of said head mass is adjacent to a portion of said flat external surface, wherein said second end surface of said head mass has a curvature which defines a centrally located contact region between a centrally located portion of said second end surface of said head mass and said flat external surface; means for assembling said acoustic driver assembly; and means for attaching said acoustic driver assembly to said flat external surface.
