Abstract
Device to collect and transmit to the cab, in motor vehicles, the acoustic signals that come from the rear, characterized in that it comprises a sensor or horn to pick up the sounds, in the bottom of which is located a diaphragm, constituted by a sheet of mica or other appropriate substance, in the center of which is a metal contact on which rests a platinum tip, which is part of a circuit, in which, in addition to a switch and the corresponding power supply, a relay is located which, by decreasing the current, - under the influence of the vibration of the diagram that increases the resistance platinum-central contact, - which normally passes through it, puts into operation a second circuit that makes act the signaling devices acoustic or luminous located in the driver's cabin.
