Patent ID: 6958568

Claim:
A cavitation system, comprising: a spherical cavitation chamber, comprising: an external surface defined by a spherical curvature; and an internal surface, wherein said spherical cavitation chamber external surface and said spherical cavitation chamber internal surface define a spherical cavitation chamber wall; an acoustic driver assembly coupled to said spherical 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 comprising: a first head mass portion and a second head mass portion, wherein a first end surface of said first head mass portion is brazed to said spherical cavitation chamber external surface, wherein said first end surface of said first head mass portion has a spherical curvature equivalent to said spherical curvature of said spherical cavitation chamber external surface, wherein a second end surface of said second head mass portion is adjacent to a second side of said at least one piezo-electric transducer, and wherein said second head mass portion includes a threaded hole; and a first threaded means coupling said first and second head mass portions; and a second centrally located threaded means coupling said tail mass, said at least one piezo-electric transducer and said second head mass portion together, wherein said second centrally located threaded means is threaded into said corresponding threaded hole in said second head mass portion.
