Abstract: An intercom system having a pair of interconnected devices, each of which has a speaker, a tap transducer, a power source and switch means, so that when they are connected together electrically, each device may be used as a transmitter or as a received, with the tap transducer in each case forming part of an electrical circuit serving both to receive and transmit signalling and sound signals, such as voice or other speech sounds. A detection device is provided for insuring that the intercom operates in that orientation thereof which provides optimum operating characteristics.

Abstract: A vibration transducer, comprising a conductive member, such as a weighted carbon bar loosely fitting into support means, such as a pair of carbon bearing blocks with the bearing blocks rigidly attached to a flexible membrane, serves as the transmitter of the voice transmission system. The bearing blocks are series wired into an electrical circuit, including a direct-current power source and a loud-speaker coil. A fluctuating pressure signal sets the flexible membrane into vibration and causes the weighted carbon bar to bounce in its bearings, thereby alternately interrupting and closing the electrical circuit. The pulsed DC signal passing through the loud-speaker coil reproduces the motion experienced by the transducer membrane in the motion of the loud-speaker cone thereby reproducing the input sound pattern.
