Abstract

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.

Claims

1. A method for controlling the distribution of audio signals among audio systems in a headset and in a base unit comprising:

determining whether the headset is ready for use;

in response to a determination that the headset audio system is ready for use, distributing audio signals from the base unit to the headset audio system;

in the absence of a determination that the headset audio system is ready for use, determining whether a base unit audio system is ready for use; and

in response to a determination that the base unit audio system is ready for use, distributing audio signals to the base unit audio system.

2. A method according to claim 1 wherein determining whether the headset is ready for use further comprises determining whether the headset is initialized and is in place on a user'"'"'s head.

3. A method according to claim 2 wherein the base unit comprises a telephone and the base unit audio system comprises an earpiece speaker in the telephone.

4. A method according to claim 3 wherein determining whether the base unit audio system is ready for use further comprises determining whether the telephone is positioned with the earpiece speaker adjacent to a user'"'"'s ear.

5. A method according to claim 4 further comprising, in the absence of a determination that the base unit audio system is ready for use, distributing the audio signals to an alternative base unit audio system.

6. A method according to claim 5 wherein the alternative base unit audio system comprises a speakerphone speaker in the telephone.

7. A method according to claim 6 further comprising providing a user-detectable alert indicating which of the audio systems is being selected.

8. An audio control system for controlling the distribution of audio signals among audio systems in a headset and in a base unit comprising:

communications control logic for receiving signals from the headset and for determining whether the received signals indicate the audio headset is ready for use by a user of the base unit;

audio control logic responsive to a determination that the headset is ready for use to distribute audio signals to the headset, said audio control logic being responsive to the absence of a determination that the headset is ready for use to determine whether a base unit audio system is ready for use and, responsive to a determination that the base unit audio system is ready for use, to distribute audio signals to the base unit audio system.

9. An audio control system according to claim 8 wherein said signals indicating the headset is ready for use further comprise signals indicating the headset is initialized and in place on a user'"'"'s head.

10. An audio control system according to claim 9 wherein the base unit comprises a telephone and the base unit audio system comprises an earpiece speaker in the telephone.

11. An audio control system according to claim 10 wherein said communications control logic is further capable of determining whether the base unit audio system is ready for use and, in the absence of a determination that the base unit audio system is ready for use, of distributing audio signals to a second base unit audio system.

12. An audio control system according to claim 11 wherein said second base unit audio system comprises a speakerphone speaker.

13. An audio control system according to claim 10 further comprising an alert generator for providing a user-detectable alert indicating which of the audio systems is being selected.

14. An audio control system according to claim 12 further comprising an alert generator for providing a user-detectable alert indicating which of the audio systems is being selected.

15. A computer program product for controlling the distribution of audio signals among audio systems in a headset and in a base unit, said computer program product comprising a computer usable medium having computer usable program code embodied therewith, said computer usable program code comprising:

computer usable program code configured to determine whether the headset is ready for use;

computer usable program code configured, in response to a determination that the headset is ready for use, to distribute audio signals to the headset;

computer usable program code configured, in the absence of a determination that the headset is ready for use, to determine whether a base unit audio system is ready for use; and

computer usable program code configured, in response to a determination that the base unit audio system is ready for use, to distribute audio signals to the base unit audio system.

16. A computer program product according to claim 15 wherein the computer usable program code configured to determine whether the headset is ready for use further comprises computer usable program code to determine whether the headset is initialized and is in place on a user'"'"'s head.

17. A computer program product according to claim 16 wherein the base unit comprises a telephone and the base unit audio system comprises an earpiece speaker in the telephone.

18. A computer program product according to claim 17 wherein said computer usable program code configured to determine whether the base unit audio system is ready for use further comprises computer usable program code for determining whether the telephone is positioned with the earpiece speaker adjacent a user'"'"'s ear.

19. A computer program product according to claim 18 further comprising computer usable program code configured to, in the absence of a determination that the telephone is positioned with the earpiece speaker adjacent a user'"'"'s ear, distribute audio signals to an alternative audio system in the telephone, said alternative audio system comprising a speakerphone speaker.

20. A computer program product according to claim 18 further comprising computer usable program code configured to generate a user-detectable alert indicating which of the audio systems is being selected.
