Abstract:
A transducer apparatus comprising:a frame member having a body portion and a flanged bottom portion; a piezoelectric film surrounding said frame member body portion and having a predetermined resonance frequency, said piezoelectric film including an inner surface facing said frame member body portion, an outer surface opposite the inner surface, and an edge surface disposed on said flanged portion of said frame member, and a securing material for securing ends of the piezoelectric film together, said securing material enabling secured ends of said piezoelectric film to have substantially the same resonance frequency as a remainder of said piezoelectric film; wherein said piezoelectric film is coupled between said frame member and a printed circuit board and electrically coupled thereto by means of ultrasonically staked pins disposed on said flanged bottom portion and in electrical communication with said printed circuit board.
