Abstract

Control of audio output characteristics of the device is contemplated. The control may correspond with modifying the audio output characteristics according to an orientation of the device or other positional relationships defined between the device, the output from the device and/or speaker positioning that may vary as a result of user manipulation or an environment within which the device is being used.

Claims

1. A method for controlling audio output characteristics of a device, the device including a plurality of speakers configured to output audio as a function of audio channels received from an audio driver, the method comprising:

controlling the output characteristics of the device according to a first characteristic when a first orientation is determined, the first characteristic dividing audio channels between at least a first speaker and a second speaker of the plurality of speakers;

controlling output characteristics of the device according to a second characteristic when a second orientation is determined, the second characteristic dividing the audio channels between the first and second speakers differently than the first characteristic; and

when the audio channels include a left front channel, a left rear channel, a right front channel and a right rear channel and the device includes a third speaker and a fourth speaker and each speaker receives no more than one of the left front, left rear, right front and right rear channels, controlling the output characteristics such that;

i) the first characteristic corresponds with;

(1) the first speaker transmitting the left front channel;

(2) the second speaker transmitting the right front channel;

(3) the third speaker transmitting the right rear channel;

(4) the fourth speaker transmitting the left rear channel; and

ii) the second characteristic corresponds with;

(1) the first speaker transmitting the right front channel;

(2) the second speaker transmitting the right rear channel;

(3) the third speaker transmitting the left rear channel; and

(4) the fourth speaker transmitting the left front channel.

2. The method of claim 1 further comprising:

determining the first orientation to correspond with an upright position of the device;

determining the second orientation to correspond with a right-side position of the device, the right-side position corresponding with a 90°

rightward rotation of the device from the upright position;

determining a third orientation to correspond with a left-side position of the device, the left-side position corresponding with a 90°

leftward rotation of the device from the upright position; and

controlling output characteristics of the device according to a third characteristic when the third orientation is determined, the third characteristic dividing the audio signals between the first and second speakers differently than at least the second characteristic.

3. The method of claim 2 further comprising:

determining a fourth orientation to correspond with an upside down position of the device, the upside down position corresponding with a 180°

rotation of the device from the upright position; and

controlling output characteristics of the device according to a fourth characteristic when the fourth orientation is determined, the fourth characteristic dividing the audio signals between the first and second speakers differently than the first characteristic.

4. The method of claim 1 further comprising:

determining the first orientation to correspond with an upright position of the device; and

determining the second orientation to correspond with a right-side position of the device, the right-side position corresponding with a 90°

rightward rotation of the device from the upright position.

5. The method claim 4 further comprising:

determining a third orientation to correspond with a left-side position of the device, the left-side position corresponding with a 90°

leftward rotation of the device from the upright position; and

controlling output characteristics of the device according to a third characteristic when the third orientation is determined, the third characteristic dividing the audio signals such that;

i) the first speaker transmits the left rear channel;

ii) the second speaker transmits the left front channel;

iii) the third speaker transmits the right front channel; and

iv) the fourth speaker transmits the right rear channel.

6. The method of claim 5 further comprising:

determining a fourth orientation to correspond with an upside down position of the device, the upside down position corresponding with a 180°

rotation of the device from the upright position; and

controlling output characteristics of the device according to a fourth characteristic when the fourth orientation is determined, the fourth characteristic dividing the audio signals such that;

i) the first speaker transmits the right rear channel;

ii) the second speaker transmits the left rear channel;

iii) the third speaker transmits the left front channel; and

iv) the fourth speaker transmits the right front channel.

7. The method of claim 1 further comprising, when the audio channels include a center channel, controlling the output characteristics such that each of the first and second characteristics correspond with the first, second, third and fourth speakers each transmitting at least a portion of the center channel.

8. A method for controlling audio output characteristics of a device, the device including a plurality of speakers configured to output audio as a function of audio channels received from an audio driver, the method comprising:

determining a first orientation to correspond with an upright position of the device;

determining a second orientation to correspond with a right-side position of the device, the right-side position corresponding with a 90°

rightward rotation of the device from the upright position;

determining a third orientation to correspond with a left-side position of the device, the left-side position corresponding with a 90°

leftward rotation of the device from the upright position;

controlling the output characteristics of the device according to a first characteristic when the first orientation is determined, the first characteristic dividing audio channels between at least a first speaker and a second speaker of the plurality of speakers;

controlling output characteristics of the device according to a second characteristic when the second orientation is determined, the second characteristic dividing the audio channels between the first and second speakers differently than the first characteristic; and

controlling output characteristics of the device according to a third characteristic when the third orientation is determined, the third characteristic dividing the audio signals such that;

i) the first speaker transmits the left rear channel;

ii) the second speaker transmits the left front channel;

iii) the third speaker transmits the right front channel; and

iv) the fourth speaker transmits the right rear channel.

9. A method for controlling audio output characteristics of a device, the device including a plurality of speakers configured to output audio as a function of audio channels received from an audio driver, the method comprising:

determining a first orientation to correspond with an upright position of the device;

determining a second orientation to correspond with a right-side position of the device, the right-side position corresponding with a 90°

rightward rotation of the device from the upright position;

determining a fourth orientation to correspond with an upside down position of the device, the upside down position corresponding with a 180°

rotation of the device from the upright position;

controlling the output characteristics of the device according to a first characteristic when the first orientation is determined, the first characteristic dividing audio channels between at least a first speaker and a second speaker of the plurality of speakers;

controlling output characteristics of the device according to a second characteristic when the second orientation is determined, the second characteristic dividing the audio channels between the first and second speakers differently than the first characteristic; and

controlling output characteristics of the device according to a fourth characteristic when the fourth orientation is determined, the fourth characteristic dividing the audio signals such that;

i) the first speaker transmits the right rear channel;

ii) the second speaker transmits the left rear channel;

iii) the third speaker transmits the left front channel; and

iv) the fourth speaker transmits the right front channel.
