Acoustic driver assembly for a spherical cavitation chamber

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 diffusion bonded 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 a corresponding threaded hole in said second head mass portion.
