Abstract

Techniques for audio control for an electronic device are discussed. The audio control for speaker channel configuration facilitates supporting proper audio stereo sound based at least in part on an orientation of the electronic device.

Claims

1. A computer readable medium comprising a plurality of instructions to facilitate operation of an electronic device according to the following process, the process comprising:

configure a rear facing speaker of the electronic device;

enable a sensor to determine an orientation of the electronic device; and

configure a volume and frequency response of the rear speaker based on the orientation of the electronic device.

2. The computer readable medium of claim 1, the process further comprising:

configure a first and a second speaker channel based on a number of speakers and the orientation of the electronic device.

3. The computer readable medium of claim 2 wherein:

configure the first speaker channel to a first and a second speaker on a same side of the electronic device upon detecting four speakers of the electronic device; and

configure the second speaker channel to a third and a fourth speaker on a different side of the electronic device upon detecting four speakers of the electronic device.

4. The computer readable medium of claim 2 wherein:

configure the first speaker channel to a first speaker upon detecting two speakers of the electronic device; and

configure the second speaker channel to a second speaker on a diagonal from the first speaker of the electronic device upon detecting two speakers of the electronic device.

5. The computer readable medium of claim 1 wherein:

configure the volume and frequency response of the rear speaker based on the orientation of the electronic device comprises a decrease in volume and a high frequency response if a vertical orientation is detected.

6. The computer readable medium of claim 1 wherein:

configure the volume and frequency response of the rear speaker based on the orientation of the electronic device comprises an increase in volume and a high frequency response if a horizontal orientation is detected.

7. The computer readable medium of claim 1 wherein:

configure the volume and frequency response of the rear speaker based on the orientation of the electronic device comprises an increase in low frequency response if a vertical orientation is detected.

8. The computer readable medium of claim 1 wherein:

configure the volume and frequency response of the rear speaker based on the orientation of the electronic device comprises an decrease in low frequency response if a horizontal orientation is detected.

9. A method for audio control of a rear facing speaker for an electronic device comprising:

detecting an orientation of the electronic device; and

adjusting a volume and a frequency response of the rear facing speaker based at least in part on the orientation.

10. The method of claim 9 wherein adjusting the volume and frequency response of the rear speaker is based on the orientation of the electronic device comprises a decreasing in volume and a high frequency response if a vertical orientation is detected.

11. The method of claim 9 wherein adjusting the volume and frequency response of the rear speaker is based on the orientation of the electronic device comprises an increasing in volume and a high frequency response if a horizontal orientation is detected.

12. The method of claim 9 wherein adjusting the volume and frequency response of the rear speaker is based on the orientation of the electronic device comprises increasing a low frequency response if a vertical orientation is detected.

13. The method of claim 9 wherein adjusting the volume and frequency response of the rear speaker is based on the orientation of the electronic device comprises decreasing a low frequency response if a horizontal orientation is detected.

14. The method of claim 9 wherein detecting the orientation of the electronic device is based on an accelerometer sensing a gravity direction to determine either a vertical or horizontal orientation.

15. The method of claim 9 wherein detecting the orientation of the electronic device is based on a sensor sensing a gravity direction to determine either a vertical or horizontal orientation.
