ABSTRACT:
Eyeglasses including a radio receiver, a radio transmitter, power supply, antenna and earphones. Said receiver, transmitter, power supply, and antenna are within the bow pieces. The antenna is a wire within the framework and extends from the rear end of one bow piece, passing through the front framework, to the rear end of the other bow piece, and is electrically connected to said transmitter and receiver circuitry. The invention, however, is not intended to be restricted to any particular construction, therefore in some but not all applications, another means to emit, or radiate, the radio waves may be used instead of the "wire" antenna. The earphones are external, and are electrically connected to said circuitry by wires entering into the bow pieces through a hole in each portion of said bow pieces. For the purpose of decreasing audible noise produced outside said eyeglasses, that would otherwise be heard by the user, even with the earphones inserted in their ears, said earphones, in some but not all applications, have the outside body covered with a sound insulating material, there-by serving as hearing protection. This construction of said earphones allows the user interference free two way radio communications, by speaking and hearing. When said user speaks, their voice travels up their Eustachian tube, and is picked up by the earphone inserted in their ear canal. The signal is carried to the transmitter by wires, where it is transmitted to another user of said eyeglass devices.
