Abstract

Disclosed is an apparatus and method for speaker equalization in a mobile device. In one embodiment, placement of a mobile device including a speaker is determined and speaker equalization is performed in accordance with the determined placement.

Claims

1. A method of performing speaker equalization for a mobile device, comprising:

determining a placement of the mobile device, wherein the mobile device includes a speaker; and

performing speaker equalization of the mobile device in accordance with the placement of the mobile device.

2. The method of claim 1, wherein performing speaker equalization further comprises:

identifying a predetermined speaker equalization configuration based at least in part on the placement of the mobile device; and

adjusting a frequency range output by a speaker of the mobile device in accordance with the predetermined speaker equalization configuration.

3. The method of claim 1, wherein the placement of the mobile device at least partially obstructs the speaker.

4. The method of claim 1, wherein the placement of the mobile device removes an obstruction to the speaker.

5. The method of claim 1, wherein the placement is relative to a physical object adjacent to the mobile device.

6. The method of claim 1, wherein determining the placement of the mobile device further comprises inferring the placement based on data from at least one of:

camera, ambient light sensor, accelerometer, magnetometer, gyroscope, barometric pressure sensor, global positioning sensor, and WiFi sensor.

7. The method of claim 1, wherein the placement of the mobile device comprises at least one of:

the mobile device is placed speaker face down on a surface, wherein the speaker is at least partially obstructed;

the mobile device is placed speaker face up on a surface, wherein the speaker is unobstructed;

the mobile device is held by a user, wherein the speaker is unobstructed; and

the mobile device is held in a concealed position, wherein the speaker is at least partially obstructed.

8. A machine readable non-transitory storage medium containing executable program instructions which cause a data processing device to perform a method comprising:

determining a placement of the mobile device, wherein the mobile device includes a speaker; and

performing speaker equalization of the mobile device in accordance with the placement of the mobile device.

9. The machine readable non-transitory storage medium of claim 8, wherein performing speaker equalization further comprises:

identifying a predetermined speaker equalization configuration based at least in part on the placement of the mobile device; and

adjusting a frequency range output by a speaker of the mobile device in accordance with the predetermined speaker equalization configuration.

10. The machine readable non-transitory storage medium of claim 8, wherein the placement of the mobile device at least partially obstructs the speaker.

11. The machine readable non-transitory storage medium of claim 8, wherein the placement of the mobile device removes an obstruction to the speaker.

12. The machine readable non-transitory storage medium of claim 8, wherein the placement is relative to a physical object adjacent to the mobile device.

13. The machine readable non-transitory storage medium of claim 8, wherein determining the placement of the mobile device further comprises inferring the placement based on data from at least one of:

camera, ambient light sensor, accelerometer, magnetometer, gyroscope, barometric pressure sensor, global positioning sensor, and WiFi sensor.

14. The machine readable non-transitory storage medium of claim 8, wherein the placement of the mobile device comprises at least one of:

the mobile device is placed speaker face down on a surface, wherein the speaker is at least partially obstructed;

the mobile device is placed speaker face up on a surface, wherein the speaker is unobstructed;

the mobile device is held by a user, wherein the speaker is unobstructed; and

the mobile device is held in a concealed position, wherein the speaker is at least partially obstructed.

15. A data processing device comprising:

a processor;

a speaker; and

a storage device coupled to the processor and speaker, the processor configurable for storing instructions, which, when executed by the processor cause the processor to;

determine a placement of the mobile device; and

perform speaker equalization of the mobile device in accordance with the placement of the mobile device.

16. The data processing device of claim 15, wherein performing speaker equalization further comprises instructions to cause the processor to:

identify a predetermined speaker equalization configuration based at least in part on the placement of the mobile device; and

adjust a frequency range output by a speaker of the mobile device in accordance with the predetermined speaker equalization configuration.

17. The data processing device of claim 15, wherein the placement of the mobile device at least partially obstructs the speaker.

18. The data processing device of claim 15, wherein the placement of the mobile device removes an obstruction to the speaker.

19. The data processing device of claim 15, wherein the placement is relative to a physical object adjacent to the mobile device.

20. The data processing device of claim 15, wherein determining the placement of the mobile device further comprises instructions to cause the processor to:

infer the placement based on data from at least one of;

camera, ambient light sensor, accelerometer, magnetometer, gyroscope, barometric pressure sensor, global positioning sensor, and WiFi sensor.

21. The data processing device of claim 15, wherein the placement of the mobile device comprises at least one of:

the mobile device is placed speaker face down on a surface, wherein the speaker is at least partially obstructed;

the mobile device is placed speaker face up on a surface, wherein the speaker is unobstructed;

the mobile device is held by a user, wherein the speaker is unobstructed; and

the mobile device is held in a concealed position, wherein the speaker is at least partially obstructed.

22. An apparatus comprising:

means for determining a placement of the mobile device, wherein the mobile device includes a speaker; and

means for performing speaker equalization of the mobile device in accordance with the placement of the mobile device.

23. The apparatus of claim 22, wherein performing speaker equalization further comprises:

means for identifying a predetermined speaker equalization configuration based at least in part on the placement of the mobile device; and

means for adjusting a frequency range output by a speaker of the mobile device in accordance with the predetermined speaker equalization configuration.

24. The apparatus of claim 22, wherein the placement of the mobile device at least partially obstructs the speaker.

25. The apparatus of claim 22, wherein the placement of the mobile device removes an obstruction to the speaker.

26. The apparatus of claim 22, wherein the placement is relative to a physical object adjacent to the mobile device.

27. The apparatus of claim 22, wherein determining the placement of the mobile device further comprises:

means for inferring the placement based on data from at least one of;

camera, ambient light sensor, accelerometer, magnetometer, gyroscope, barometric pressure sensor, global positioning sensor, and WiFi sensor.

28. The apparatus of claim 22, wherein the placement of the mobile device comprises at least one of:
