Title:
EARPHONES AND MICROPHONE (PERSONAL SPEAKING DEVICE) THAT DO NOT TRANSMIT OR EMIT MICROWAVE RADIATION OR ANY OTHER DANGEROUS RADIATION
Document Type and Number:
WIPO Patent Application WO2001078442
Kind Code:
A3
Abstract:
Cellular phones (15) are becoming more common and popular amongst all sectors of the population for business and private conversations, including many children, with about 500 Million users worldwide, and about 300,000 new joiners each day. There is much concern and there is already some accumulating evidence that the Microwave emission transmitted by the cellular antenna that is held close to user's head may have deleterious effect on the user, such as for example brain or eye cancer, and possible even more so for children. The present invention solves the above problem in using earphone (11) with cellular phones (15) and similar device. This is accomplished by the elimination of any electrically conducting materials from the connection between the personal speaking device (13) and the phone (15), such as for example by use of optic fibers (14), so that the personal speaking device no longer act as an antenna. Many possible variations and also deviations from this basic design are shown.
