Abstract
Electronic device to allow acoustic warning to drivers of motor vehicles, they are external audibility, characterized by the fact of constituting a transmitting and receiving part of very high frequencies, without modulating or modulating, the transmitter carrying a rod antenna that radiates in all directions with equal power and the receiver, directional antennas that receive the signal in a concentrated manner in a certain direction, transforming this receiving part the radioelectric energy captured, either in mechanical movement by means of a relay to open and close an electric circuit that operates a buzzer, if that is unmodulated, either amplifying it at low frequency to make audible the signals on the loudspeaker, if that is modulated, going all mounted on the chassis and metal box and the circuits in connection with the vehicle's battery for feeding, preferably locating the receiving antennas, one in each side and another in the rear of the vehicle, also giving the circumstance of producing acoustic signal with the driver, the emissions of signals that this is producing to warn another vehicle, all being connected to each other according to technique.
