Abstract (en)
An electronic device is provided which, when connected to electrical equipment, such as an electric guitar, an electric keyboard or a video cassette recorder (VCR), will effect wireless transmission over a selectable frequency of the FM broadcast band. In a preferred embodiment of the invention, the electric guitar, the device uses the metal strings of the guitar as a partial antenna. The unit remains stationary after being plugged into the guitar's input receptacle, and no transmitting portion of the device has to be attached to the musician's belt or guitar strap, or to the musician's person in any fashion. Furthermore, no large unsightly, cumbersome antenna extends from the device itself. The device is automatically turned on when plugged in. As noted above, through modification of the circuitry of the electronic device contemplated, the device may be used for transmission of audio signals to a remote FM receiver when connected to an audio output jack of standard electrical equipment.
