INCREASING ANTENNA PERFORMANCE FOR WIRELESS HEARING ASSISTANCE DEVICES

摘要

Disclosed herein, among other things, are methods and apparatus for increasing antenna performance for hearing assistance devices. One aspect of the present subject matter includes a receiver-in-canal (RIC) hearing assistance device for a wearer including an antenna within a device housing, an audio receiver configured to be worn in an ear canal of a wearer, and a cable assembly configured to connect the audio receiver to the device housing. A ferrite element or an inductor is connected to the cable assembly and configured to reduce unwanted coupling between the cable assembly and the antenna by reducing high frequency current through the wires of the cable assembly. According to various embodiments, the ferrite element or the inductor is connected in series to the cable assembly adjacent to the device housing.
