Patent ID: 7126256

Claim:
A cavitation system, comprising: a cylindrical cavitation chamber, comprising: a cylindrical external surface; and a cylindrical internal surface, wherein said cylindrical external surface and said cylindrical internal surface define a cavitation chamber wall; an acoustic driver assembly coupled to said cylindrical 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 cylindrical external surface, wherein said second end surface of said head mass has a curvature which defines a ring of contact between an outer perimeter of said second end surface of said head mass and said cylindrical external surface; means for assembling said acoustic driver assembly; and means for attaching said acoustic driver assembly to said cylindrical external surface.
