Abstract

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

Claims

1. An electronic device comprising:

a speaker control module to detect an orientation of the electronic device and a number of front facing speakers of the electronic device;

a first and a second front facing speaker, coupled to the speaker control module, to be assigned a speaker channel based on the detected orientation of the electronic device; and

the speaker control module to control a volume and a frequency response of a rear speaker based on the orientation of the electronic device.

2. The electronic device of claim 1 wherein:

the speaker control module to assign a first speaker channel to a first and a second speaker on a same side of the electronic device if the detection indicates four front facing speakers for the electronic device; and

to assign the second speaker channel to a third and a fourth front facing speaker on a different side of the electronic device if the detection indicates four speakers for the electronic device.

3. The electronic device of claim 1 wherein:

the speaker control module to a first speaker channel to a first speaker if the detection indicates two front facing speakers for the electronic device; and

to assign the second speaker channel to a second speaker on a diagonal from the first front facing speaker of the electronic device if the detection indicates two front facing speakers for the electronic device.

4. The electronic device of claim 1 wherein the speaker control module comprises an accelerometer that senses a gravity direction to determine either a vertical or a horizontal orientation.

5. The electronic device of claim 1 wherein the speaker control module comprises a proximity sensor to determine either a horizontal or vertical orientation.

6. A audio control circuit comprising:

an input to the audio control circuit from a sensor to determine a nearly vertical or horizontal orientation of an electronic device;

the audio control circuit to output a volume and a frequency response to a rear facing speaker based at least in part on the vertical or horizontal orientation of the electronic device.

7. The audio control circuit of claim 6 wherein a volume and a high frequency response is increased if the sensor indicates a horizontal orientation.

8. The audio control circuit of claim 6 wherein a volume and a high frequency response is decreased if the sensor indicates a vertical orientation.

9. The audio control circuit of claim 6 wherein a low frequency response is increased if the sensor indicates a vertical orientation.

10. The audio control circuit of claim 6 wherein a low frequency response is decreased if the sensor indicates a horizontal orientation.
