"Hear Speak" Two-Way Voice Radio Communications Eyeglasses

The present invention relates to the general art of two-way voice radio communications and to the particular field of combinations which include two-way voice radio communications equipment.

The "Hear-Speak Eyeglasses" (including any kind of eyeglasses, even toys) are a form of two-way voice radio communications. The radio communications equipment is in the glasses frames. The applications of this form of communications can range from a childs toy, to a soldiers life saver. It can be incorporated in safety glasses for industry, sunglasses for eye protection such as motorcycle riders would use, or for private conversation without hearing outside noise in such enviornments as restaurants, auto race tracks, etc. Depending on the application, the designs would vary. Some would have one earphone, while others would have two. Some of the earphones would be covered with a sound insulating material for use in a noisy environment. On some occasions a worker in a noisy industrial plant may leave the noisy environment and enter a quiet office to communicate with a person working in the office. The design of such "Hear-Speak" eyeglasses would have an ambient sound switch to allow the user to switch to outside sound. This would enable the user to leave the glasses on and earphones plugged in their ears. It is apparent that this invention could be a life saver in many applications.

It is an object of the present invention to provide convenient, hands free, two-way radio communications, usable by persons in a variety of work and other activities.

It is another object of the present invention to provide convenient hands free two-way voice radio communications which provide both eye and hearing protection.

It is another object of the present invention to provide convenient hands free two-way voice radio communications in the form of eyeglasses with rechargable batteries and solar batteries.

These, and other, objects are achieved by the combination of, two-way voice activated radio communications equipment and eyeglasses frames in a manner that well keep the eyeglasses comfortable to the user, even for long periods of time. This would be accomplished by removing an amount of frame material, equal in weight, to the weight of electronic circuitry to be added. That is to say, said circuitry will be designed to weigh as much, or less than, the material removed to integrate said circuitry into eyeglass frames. (The complete frames, including that which holds the lens.)

Earphones 8 and 27 are interchangeable, and available in different sizes, and slip onto earphones. When the power is turned on the "Hearspeak" two way radio communications eyeglasses well be in the receiver mode. (circuit 32 on circuit board 33) In this mode the user is able to hear a voice communications transmitted from a transmitter using the same radio frequency. This transmission will penetrate, and or, radiate through free space, air, wood, vacuum, gasses, most liquids and some solids, and is called radio frequency or RF. When RF is used in the present invention there are no wires connected from one device to the other. The "Hearspeak" two way voice radio communications eyeglasses are not designed to be a hearing aid for the "hearing impaired" When the user speaks, the voice activated switch 46 turns the users RF receiver 32 off, and turns the users RF transmitter 16 on. The users voice is radiated from the antenna, or by light wave through "free space" where it is received by another RF receiver operating at that frequency. In the event the user wishes to communicate with someone in a noise free environment there is an ambient sound switch 52 and ambient sound amplifier 47 to allow audio frequency reception without removing the earplugs. the earphone serves as a microphone in the RF voice transmission mode. 48 is a volume control.
