Abstract

A wireless stereo headphone is provided that permits a user to listen to a stereo program being received by a conventional receiver/amplifier without the use of interconnecting wires. A transmitter contained within the headphones allows the user to remotely activate the SCAN and SEEK features of the receiver so that not only can he monitor a program and vary its volume, he can also select the program material.

Claims

1. A wireless stereo headphone comprising:

(a) a left and a right earphone;

(b) a stereo headphone receiver contained in said headphone wherein the left and right outputs of said stereo receiver are connected to said left and right earphones respectively;

(c) a headphone antenna connected to said stereo headphone receiver;

(d) a plug-in accessory stereo transmitter;

an accessory antenna for said accessory transmitter;

a housing for said accessory transmitter; and

a stereo plug, wherein said plug protrudes from said housing, and is positioned in such a way as to allow said plug to be inserted into the headphone jack of conventional stereo receiver/amplifier having SEEK and SCAN functions;

wherein the audio output of said conventional receiver/amplifier is transmitted from said accessory stereo transmitter to said stereo headphone receiver so that a user can listen to program material without being tied by a cable to said conventional receiver/amplifier; and

(e) a headphone transmitter contained in said headphone, a momentary contact SEEK switch, and a momentary contact SCAN switch;

wherein the depression of either of said switches causes a uniquely encoded signal to be transmitted via said headphone antenna; and

means for decoding said encoded signal such that SEEK and SCAN functions in said conventional receiver/amplifier may be remotely controlled when the respective said momentary contact switches are depressed.

2. A wireless stereo headphone, as recited in claim 1, wherein said means for decoding said encoded signal comprises a decoding module whose input is said encoded signal, received via said accessory antenna;

and whose output is a switching signal that goes from off to on when a user depresses said momentary contact SEEK switch, and a switching signal that goes from off to on when a user depresses said momentary contact SCAN switch, where said outputs are used to control the SEEK and SCAN functions of said conventional receiver/amplifier.
