Abstract
A mobile station includes an adjustable member for increasing a separation distance between an audio signal output device and an electronic circuit to reduce EMI proximate the audio signal output device caused by the electronic circuit. In one embodiment, the adjustable member comprises a slide member that extends at least a portion of the audio signal output device away from the electronic circuit to increase the separation distance. In another embodiment, the adjustable member comprises a pivot member that rotates the electronic circuit (or audio signal output device) away from the audio signal output device (or electronic circuit) to increase the separation distance. In any event, increasing the separation distance between the audio signal output device and the electronic circuit decreases the EMI proximate the audio signal output device, and therefore EMI effects on external circuits proximate the mobile station, such as a hearing aid.
