Headset with programmable microphone modes
View Patent ↗A method and system for a headset with programmable modes, where the headset comprises a speaker and a beamforming microphone: sensing an ambient sound level near the headset, and configuring the headset in one of a plurality of modes by configuring a beam pattern of the beamforming microphone based on at least the sensed ambient noise level. A user of the headset may configure the headset in the one of the plurality of modes or it may be automatically configured. The beamforming microphone may comprise an array of sound sensing elements. The headset may be configured in a quiet mode when the sensed ambient sound level is below that of a desired sound source and may be configured with a wide beam pattern. The headset may be configured in a loud mode when the sensed ambient sound level is above that of a desired sound source.
1. A system for processing audio signals, the system comprising:
a headset comprising:
a speaker;
a beamforming microphone configured to sense an ambient sound level near the headset of sounds external to the headset; and
an audio processing unit that configures the headset in one of a plurality of modes by configuring a beam pattern of the beamforming microphone comprising a plurality of microphone elements, said mode configuration based on at least the sensed ambient sound level, wherein the headset is configured in a wider quiet mode beam pattern when the sensed ambient sound level is below a level of sound from a user of the headset and in a narrower loud mode when the sensed ambient sound level is above the level of sound from the user of the headset.
2. The system of claim 1 , wherein the user of the headset configures the headset in the one of the plurality of modes.
3. The system of claim 1 , wherein the headset automatically configures itself in the one of the plurality of modes.
4. The system of claim 1 , wherein the beamforming microphone comprises an array of sound sensing elements.
5. The system of claim 1 , wherein the headset is configured in one of the plurality of modes on a continuous basis during operation of the headset.
6. The system of claim 1 , wherein the beamforming microphone is configured with a wide beam pattern with full sensitivity from all directions when the headset is in the quiet mode.
7. The system of claim 1 , wherein the headset is configured in a loud mode with the beamforming microphone configured with a narrow beam in a particular direction when the sensed ambient sound level is above that of a desired sound source.
8. The system of claim 7 , wherein the beamforming microphone is configured with a narrow beam pattern directed at the desired sound source when the headset is in the loud mode.
9. The system of claim 1 , wherein the headset is configured in the one of the plurality of modes based on a location of the headset.
10. The system of claim 1 , wherein the headset is configured in the one of the plurality of modes by a gaming console.
11. A method for processing audio signals, the method comprising:
in a headset that comprises a speaker, audio processing circuitry, and a beamforming microphone comprising a plurality of microphone elements:
sensing, using the beamforming microphone, an ambient sound level near the headset of sounds external to the headset; and
configuring, using the audio processing circuitry, the headset in one of a plurality of modes by configuring a beam pattern of the beamforming microphone based on at least the sensed ambient sound level, the headset being configured in a wider quiet mode beam pattern when the sensed ambient sound level is below a level of sound from a user of the headset and in a narrower loud mode beam pattern when the sensed ambient sound level is above the level of sound from the user of the headset.
12. The method of claim 11 , wherein the user of the headset configures the headset in the one of the plurality of modes.
13. The method of claim 11 , comprising automatically configuring the headset in the one of the plurality of modes.
14. The method of claim 11 , wherein the beamforming microphone comprises an array of sound sensing elements.
15. The method of claim 11 , comprising configuring the headset in one of the plurality of modes on a continuous basis during operation of the headset.
16. The method of claim 11 , comprising configuring the beamforming microphone with a wide beam pattern with full sensitivity from all directions when the headset is in the quiet mode.
17. The method of claim 11 , comprising configuring the headset in a loud mode with the beamforming microphone configured with a narrow beam in a particular direction when the sensed ambient sound level is above that of a desired sound source.
18. The method of claim 17 , comprising configuring the beamforming microphone with a narrow beam pattern directed at the desired sound source when the headset is in the loud mode.
19. The method of claim 11 , comprising configuring the headset in the one of the plurality of modes utilizing a gaming console.
20. A system for processing audio signals, the system comprising:
a headset operable to communicatively couple to a gaming console, the headset comprising:
a speaker;
a beamforming microphone comprising a plurality of microphone elements operable to sense an ambient sound level near the headset of sounds external to the headset; and
audio processing circuitry that configures the headset in one of a plurality of modes by configuring a beam pattern of the beamforming microphone based on at least the sensed ambient sound level wherein the headset is configured in a wider quiet mode beam pattern when the sensed ambient sound level is below a level of sound from a user of the headset and in a wider loud mode when the sensed ambient sound level is above the level of sound from the user of the headset.
