Abstract

A networked speaker system automatically adjusts certain audio speaker system settings based on whether the system is inside a building or has been moved outside as may be sensed by one or capacitors on a speaker. Also, techniques are described for adjusting speaker driver direction based on walls or other barriers in a room or based on the location of a listener.

First claim

What is claimed is:

1. A device comprising:
at least processor configured with instructions to:
receive, from at least one sensor on a wall of a speaker disposed on a surface, at least one signal representing a type of the surface on which the speaker is disposed;
based at least in part on the signal, identify at least one speaker configuration at least in part using a data structure correlating signals from the at least one sensor to speaker configuration, or correlating signals from the at least one sensor to surface type and correlating surface type to speaker configuration, the at least one speaker configuration comprising at least one speaker setting other than volume; and
establish the speaker configuration on the speaker such that the speaker emits audio according to the at least one speaker setting.

2. The device of claim 1 , comprising the sensor.

3. The device of claim 1 , comprising the speaker.

4. The device of claim 1 , wherein the speaker configuration comprises a speaker system channel configuration.

5. The device of claim 1 , wherein the speaker configuration comprises a compression setting.

6. The device of claim 1 , wherein the speaker configuration comprises extra bass.

7. The device of claim 1 , wherein the speaker configuration comprises equalization (EQ).

8. The device of claim 1 , wherein the speaker configuration comprises ambient sound attenuation.

9. The device of claim 1 , wherein the instructions are executable to:
identify at least one speaker configuration at least in part using a data structure correlating signals from the at least one sensor to speaker configuration.

10. A method, comprising:
receiving a signal from a sensor on an exterior wall of a housing of a speaker that rests against a supporting surface such that the signal depends on a type of the supporting surface; and
establishing at least one speaker configuration other than volume of the speaker based at least in part on the signal at least in part using a data structure correlating signals from the sensor to speaker configuration, or correlating signals from the sensor to surface type and correlating surface type to speaker configuration, the speaker configuration comprising at least one speaker setting.

11. The method of claim 10 , comprising:
establishing at least one speaker configuration of the speaker based at least in part on the signal at least in part using a data structure correlating signals from the sensor to speaker configuration.

12. The method of claim 10 , wherein the speaker configuration comprises a speaker system channel configuration.

13. The method of claim 10 , wherein the speaker configuration comprises a compression setting.

14. The method of claim 10 , wherein the speaker configuration comprises ambient sound attenuation.

15. The method of claim 10 , wherein the speaker configuration comprises extra bass.

16. The method of claim 10 , wherein the speaker configuration comprises equalization (EQ).

17. The method of claim 10 , wherein the speaker configuration comprises delay.

18. The method of claim 10 , wherein the signal represents capacitance.

19. The device of claim 1 , wherein the instructions are executable to:
identify at least one speaker configuration at least in part using a data structure correlating signals from the at least one sensor to surface type and correlating surface type to speaker configuration.

20. The method of claim 10 , comprising:
establishing at least one speaker configuration of the speaker based at least in part on the signal at least in part using a data structure correlating signals from the sensor to surface type and correlating surface type to speaker configuration.

21. An audio speaker system, comprising:
at least a first audio speaker; and
at least one processor configured with instructions for:
establishing a first audio configuration of the first audio speaker responsive to a first signal from a first sensor mounted on a first wall of a housing of the first audio speaker, the first audio configuration comprising plural settings other than volume; and
establishing a second audio configuration of the first audio speaker responsive to a second signal from a second sensor mounted on a second wall of the housing of the first audio speaker, the second audio configuration comprising plural settings other than volume with values different from values of at least some of the plural settings of the first audio configuration.

22. The audio speaker system of claim 21 , comprising plural capacitance sensors mounted on respective surfaces of the housing.
