Cellular phones 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 effects on the user, such as for example brain or eye cancer, and possibly even more so for children. One of the most common ways to try to avoid these problems has been the usage of personal earphones with microphone, but on 4/4/2000 it was published worldwide that a research conducted by the "Which?" consumer Magazine in Britain found that in fact the earphone and its cable can act as an Antenna and also expose the user to the microwave radiation. The present invention solves the above problem in using earphones with cellular phones by a reverse and more sophisticated solution than short range wireless earphones, and also solves the problem that many people don t like using headsets at all. |
