Abstract
A method for constructing a parametric transducer. The method includes preparing a support member having opposing front and back surfaces, the support member extending along an x-axis and a y-axis. The support member is structured to retain an array of parallel ridges extending along the x-axis and spaced apart along the y-axis at predetermined separation distances. The ridges have forward, film contacting faces to support an emitter film in a desired film configuration for emitting parametric output. An electrically sensitive and mechanically responsive (ESMR) film is applied to the support member with one side of the ESMR film being captured at the film contacting faces, and with arcuate sections disposed between the parallel ridges. The film contacting faces mechanically isolate each of the arcuate sections of ESMR film from adjacent arcuate sections.
