AUDIO SELECTION CONTROL FOR PERSONAL COMMUNICATION DEVICES
摘要:
The distribution of audio signals to either a headset or to a base unit (such as a cell phone) is determined by whether the headset is ready for use when a call is made or received. The headset is considered ready for use if it is powered on, has been initialized to exchange signals with the base unit using a standard communications protocol (such as Bluetooth), and is in place on the user's head. The headset includes a proximity sensor that provides a signal indicating that the headset is in place. If the headset is ready for use, audio signals are automatically distributed to the headset. Otherwise, the audio signals were distributed to a cell phone audio system. The invention may also be used by a personal computer user having an audio headset.
