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.

Method and apparatus for improved mobile station and hearing aid compatibility

An audio signal received at a mobile device is processed using a first set of equalization parameters in an acoustic coupling mode of operation, and is processed using a second set of equalization parameters in an inductive coupling mode of operation. The processed audio signal is transmitted to a speaker associated with the mobile device for acoustic coupling to a human ear and/or a hearing aid microphone, or for inductive coupling to a hearing aid telecoil.

A wireless communications device can include a power amplifier that is configured to transmit information to a wireless communications network during a first time interval and configured to avoid transmitting information during a second time interval. A circuit substrate is coupled to the power amplifier and a power source is configured to provide power to the power amplifier. First and second conductor are coupled to the power amplifier and to the power source, and have respective overlapping and non-overlapping portions on the circuit substrate.

A tactile generator comprises an eccentric mass that imparts a vibration as it rotates about a rotational axis. The mass is radially movable with respect to the rotational axis such that the distance between the mass and the axis is variable. Varying the distance of the mass from the axis varies the amount of vibration generated when the mass is rotated. The amount of vibration may be controlled responsive to a detected level of ambient noise.
