Abstract

Abstract The present invention is a stereo headset system for use with a stereo headset device and a stereo sound system. The stereo headset device is of the stethoscope type and has a pair of sound tubular mains. A coupling plug is mechanically and acoustically coupled to the pair of sound tubular mains. The stereo headset system includes an enclosure having a first chamber, a second chamber, a third chamber and a fourth chamber. The first and second chambers are mechanically and acoustically coupled to the coupling plug of the stereo headset device. A first electro-acoustic transducer is disposed in the third chamber of the enclosure and is acoustically coupled to the first chamber of the enclosure. A second electro-acoustic transducer is disposed in the fourth chamber of the enclosure and is acoustically coupled to the second chamber of the enclosure. The third and fourth chambers of the enclosure are water-proofed. A control unit includes a double pole relay and a double potentiometer both of which electrically couple in series the two output channels of the stereo sound system to the first and second electro-acoustic transducers so that the stereo headset system is able to transmit sounds from the stereo sound system through the stereo headset device to an individual who is in a wet environment during both social and recreational periods.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 203 words
A stereo headset system for use with a stereo sound system and a stereo headset device of the stethoscope type having a pair of sound tubular mains and a coupling plug which is mechanically and acoustically coupled to the pair of sound tubular mains, said stereo headset system comprising: a. an enclosure having a first chamber, a second chamber, a third chamber and a fourth chamber with said third and fourth chambers being mechanically and acoustically coupled to the coupling plug of the stereo headset device; b. a first electro-acoustic transducer which is disposed in said first chamber of said enclosure and which is acoustically coupled to said third chamber of said enclosure; c. a second electro-acoustic transducer which is disposed in said second chamber of said enclosure and which is acoustically coupled to said fourth chamber of said enclosure; d. water-proofing means for water-proofing said first and second chambers of said enclosure; and e. electro-coupling means for electrically coupling said first and second electro-acoustic transducers to the stereo sound system whereby said stereo headset system transmits sounds from the stereo sound system through the stereo headset device to an individual who is in a wet environment during both social and recreational periods.
Claim 2
Dependent Claim 203 words
A stereo headset system for use with a stereo sound system and a stereo headset device of the stethoscope type having a pair of sound tubular mains and a coupling plug which is mechanically and acoustically coupled to the pair of sound tubular mains, said stereo headset system comprising: a. an enclosure having a first chamber, a second chamber, a third chamber and a fourth chamber with said third and fourth chambers being mechanically and acoustically coupled to the coupling plug of the stereo headset device; b. a first electro-acoustic transducer which is disposed in said first chamber of said enclosure and which is acoustically coupled to said third chamber of said enclosure; c. a second electro-acoustic transducer which is disposed in said second chamber of said enclosure and which is acoustically coupled to said fourth chamber of said enclosure; d. water-proofing means for water-proofing said first and second chambers of said enclosure; and e. electro-coupling means for electrically coupling said first and second electro-acoustic transducers to the stereo sound system whereby said stereo headset system transmits sounds from the stereo sound system through the stereo headset device to an individual who is in a wet environment during both social and recreational periods.
