ABSTRACT:
A flexible acoustic coupler includes a pair of muffs and at least one acoustic-electrical transducer located in one of the muffs. Each of the muffs is arranged to support either the mouthpiece or earpiece of a conventional telephone handset. The muffs, in turn, are joined by a flexible coupling element which normally supports the muffs spaced apart so as to be mated in acoustic coupling relation with a conventional telephone handset. The flexible coupling element, however, is capable of flexing so that one muff can be rotated 180.degree. with respect to the other muff and mated therewith to thereby reduce the space taken up by the coupler when not operating. In implementation, the flexible coupling element and both muffs are integrally molded providing an attractive and efficient low cost acoustic coupler.
