ABSTRACT:
An acoustic coupler such as commonly used to receive and transmit data between computer terminals over telephone lines. The acoustic coupler is constructed in two halves joined by a flexible hinge which permits the two halves to move laterally and rotationally (about the hinge) with respect to each other. Each half of the acoustic coupler is also provided with a strap for securing the telephone handset portion in place upon the acoustic coupler halves. Once secured in place the telephone handset portion can be used as a "handle" to pick up and move the acoustic coupler from place to place. One half of the acoustic coupler contains a speaker, the other half contains a microphone, which may be electrically coupled to one another by electrical paths passing through, or forming a part of, the flexible hinge member.
