A wireless speaker (10) for a radio communication device (12) includes a remote housing with a clothing attachment clip. A receiver circuit is disposed within the housing. The receiver circuit is adapted to receive signals (20) carrying audio information from the radio communication device (12). A battery within the housing powers the receiver. The receiver circuit converts the signals (20) received from the radio communication device (12) to audio signals that are then coupled to the speaker. The earpiece may be carried on a hookswitch when not in use, which automatically disconnects the headset jack from the receiver and connects the speaker to the receiver. The earpiece may be an earbud, earpiece or headset with a wired connection to the headset jack. The speaker may be clipped to the lapel or another piece of clothing close to the user's ear, so that some privacy may be afforded to the user, and low power levels used. The wireless link from the earphones may be optical, ultrasonic or radio frequency. The mobile communications device may be worn on the users wrist. |
