ABSTRACT:
An electrostatic transducer includes a thin flexible diaphram portion, two electrode portions and a frame portion. The electrode portions and the diaphram portions are constructed in accordance with U.S. Pat. No. 3,668,335. The frame portion is comprised of two single-piece frame halves each having an "L" shaped cross section with vertical and horizontal legs. The vertical legs include channels cut into their longer dimensions. Each frame-half piece is bent into a rectangular shape to surround one of the electrodes which is retained within the frame-half by a bead of epoxy which extends into the channels on the frame-half to make a relatively rigid frame-half and electrode assembly. Two such assemblies are then affixed to each other with the diaphram tightly stretched in between.
