Abstract

A parametric transducer which includes a support member extending along an x-axis and a y-axis and having opposing front and back surfaces. The support member (102) includes an array of parallel ridges (108) extending along the x-axis and spaced apart along the y-axis at predetermined separation distances. The ridges have forward, film contacting faces (112) to support an emitter film (114) in a desired film configuration for emitting parametric output. An electrically sensitive and mechanically responsive (ESMR) film is disposed over the support member with one side of the ESMR film (114) being captured by the film contacting faces, and with arcuate sections aligned with and positioned between the parallel ridges. The film contacting faces mechanically isolate each of the arcuate sections (110) of ESMR film from adjacent arcuate sections.
