Abstract:
1. A piezoelectric transducer comprising: a) a chamber diaphragm having an upper surface, a lower surface, and at least two sub-chamber diaphragms wherein each sub-chamber diaphragm has a sub-chamber diaphragm perimeter. b) at least one sub-chamber diaphragm support structure having at least two gaps therethrough, adjacent to one of the upper surface or lower surface of the chamber diaphragm, wherein each gap has a gap perimeter, the gap perimeter of each gap being substantially coincident with one of the sub-chamber diaphragm perimeters. c) at least two piezoelectric material elements adjacent to one of the upper surface or lower surface of the chamber diaphragm so constructed and arranged as to be aligned with the at least two gaps of the sub-chamber diaphragm support structure.
