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:
• a first piezo-electric transducer with a first surface and a second surface;
• a second piezo-electric transducer with a first surface and a second surface, wherein said first surface of said first piezo-electric transducer and said first surface of said second piezo-electric transducer are in electrical contact, and wherein a polarity corresponding to said first surface of said first piezo-electric transducer is equivalent to a polarity corresponding to said first surface of said second piezo-electric transducer;
• a tail mass adjacent to said second side of said first 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 said second side of said second piezo-electric transducer and said second end surface of said head mass is adjacent to a portion of said spherical cavitation chamber external surface, wherein said second end surface of said head mass has a spherical curvature equivalent to said spherical curvature of said spherical cavitation chamber external surface;
• a first centrally located threaded means coupling said tail mass, said at least one piezo-electric transducer and said head mass together, wherein said first centrally located threaded means is threaded into a corresponding threaded hole in said head mass;
• a second centrally located threaded means, wherein a first end portion of said second centrally located threaded means is threaded into said head mass and a second end portion of said second centrally located threaded means is threaded into a corresponding threaded hole in said spherical cavitation chamber external surface;
• and
• an insulating sleeve surrounding a portion of said first centrally located threaded means, wherein said insulating sleeve electrically insulates said first and second piezo-electric transducers from said first centrally located threaded means.
