ABSTRACT:
This universal acoustic coupler system is comprised of a pair of flexible muffs, which are rotatably mounted to permit connection to any length telephone handset receiver/transmitter; this feature also permits any varying angles of the earpiece and mouthpiece. Furthermore, the elastic structure of the muff permits the insertion of any size earpiece and mouthpiece, thereby allowing use of the muffs on an international scale. The muffs are comprised of a pair of elastic, generally circular housings, which include a speaker/microphone cavity and an earpiece/mouthpiece cavity, separated by an acoustic cavity. Features include flexible mounting arms or hinges attached to each of the muff housings. These arms have a circular aperture therein to accommodate a retaining pin which attaches the acoustic muff to an electronic input/output device. The muff attaches externally to the electronic device, and the housing folds back to overlie the mounting arms when a storage cover is put in place over the input/output device.
