Safety telephone set for transmitting and receiving speech in motor vehicles and cabins

摘要

With the telephone set for motor vehicles and cabins, voice and tones can be received and transmitted by the arrangement of isolated units in ergonomic positions in relation to the hands, ears and mouth: console (keypad/controls, between the two front seats, or on a retractible arm rest between passengers on the rear seat; and also to the side or in front of the cabin occupant); connects with the transceiver unit and battery system of the permanently installed/car/mobile telephone or with a "walkie-talkie"-type broadcast receiver and transmitter; at least one microphone within the speaking range of the driver, the front-seat passenger and the rear-seat passenger; and at least one loudspeaker within the hearing range of the driver, the front-seat passenger and the rear-seat passenger. The use of isolated units during a call (console, microphones, loudspeakers), as opposed to the use of an individual telephone handset (which would be held with one hand to the ear and mouth) frees the driver's hands to steer the car safely and to keep his attention on the road; also frees the hands of the cabin occupants to manipulate the switches or other objects more efficiently.
