<p>An air transducer apparatus (2A and 2B) comprising a curved piezoelectric film (26) having a first electrode surface (200) and a second surface (210), a first electrode layer (200) disposed on at least a portion of the first surface of the film (26); and a second electrode layer (210) disposed on a portion of the second surface of the film (26B) defining the second electrode layer (210) being sizxed less than the first electrode layer (200) generating a signal in response to acoustic energy incident on the piezoelectric film (26).</p> |
