Abstract
An acoustic driver assembly for use with any of a variety of cavitation chamber configurations, including spherical and cylindrical chambers as well as chambers that include at least one flat coupling surface, is provided. The acoustic driver assembly includes at least one transducer, a head mass and a tail mass. The end surface of the head mass is shaped so that only a ring of contact is made between the outer perimeter of the head mass of the driver assembly and the cavitation chamber to which the driver is attached. The area of the contact ring is controlled by shaping its surface.
Claims27
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.
