Abstract
A shield apparatus for placement over speaker openings of a cellular or cordless telephone to obstruct passage of harmful electromagnetic signal radiation from the telephone to the user ear includes a first glue ring for bonding the apparatus over the speaker openings of a telephone; a first mesh layer adhesively engaged by the first glue ring for absorbing signal radiation while permitting passage of sound waves; a second glue ring adhesively engaging the first mesh layer; and a second mesh layer engaged by the second glue ring for absorbing residual signal radiation penetrating the first mesh layer. The apparatus preferably still additionally includes a metal frame ring bonded to the second mesh layer and extending along the periphery of the second mesh layer for absorbing radiation directed laterally toward the user ear.
