ABSTRACT:
Telephone coupling devices which are used to connect various devices into telephone networks without electrical connections require structure which will provide effective acoustic coupling with telephone handsets produced by a variety of manufacturers, many of which differ from each other not only in major dimensional characteristics but also in specific construction. An acoustic coupler having a dimensionally bi-stable flexible coupling element permits use of the coupler of the present invention with an unlimited number of telephone handset configurations.
