Radio-frequency hearing aid protector for wireless communications products
Abstract
A wireless communications device with low magnetic field emission is provided by disposing a magnetically absorptive material near the base of an antenna of a handset of the device. The magnetically absorptive material is preferably a ferrite-type metal oxide dispersed within a silicone rubber medium. The ferrite-type metal oxide acts to attenuate the magnetic field generated in the near field of the antenna. Interference with hearing aids worn by wireless communications device users is thereby reduced.
