Abstract

Systems, methods, and apparatus for frequency routing based on orientation are disclosed. An example method includes receiving, by a playback device, an audio data stream. The example method includes determining, by the playback device, an orientation of the playback device. The example method includes routing, by the playback device, a first set of frequencies in the audio data stream to at least one of a plurality of speaker drivers based on the first orientation. The example method includes routing, by the playback device, a second set of frequencies in the audio data stream to the at least one of the plurality of speaker drivers based on the second orientation, wherein the first set of frequencies is different than the second set of frequencies.

First claim

The invention claimed is:

1. A first playback device comprising:
at least one processor;
at least one orientation sensor;
a plurality of speakers comprising a first speaker and a second speaker; and
at least one tangible, non-transitory computer-readable medium comprising program instructions that are executable by the at least one processor such that the first playback device is configured to:
while receiving multi-channel audio content from a media source, determine whether the first playback device is paired with a second playback device and use the orientation sensor to determine an orientation of the first playback device;
while the first playback device is not paired with the second playback device and when the first playback device is determined to be in a first orientation, play a first channel of the multi-channel audio content via the first speaker and play a second channel of the multi-channel audio content via the second speaker;
while the first playback device is not paired with the second playback device and when the first playback device is determined to be in a second orientation, play the first channel of the multi-channel audio content via the second speaker and play the second channel of the multi-channel audio content via the first speaker; and
while the first playback device is paired with the second playback device regardless of orientation of the first playback device, provide the first channel of the multi-channel audio content and the second channel of the multi-channel audio content to the second playback device for playback.

2. The first playback device of claim 1 , wherein the at least one orientation sensor comprises an accelerometer.

3. The first playback device of claim 1 , wherein the first playback device is configured to play audiovisual content, wherein the audiovisual content comprises video content and the multi-channel audio content, and wherein the first playback device further comprises:
a display screen configured to display the video content of the audiovisual content.

4. The first playback device of claim 1 , wherein the first orientation comprises a horizontal orientation, and wherein the second orientation comprises a vertical orientation.

5. The first playback device of claim 1 , wherein the first orientation comprises the first speaker facing a first direction and the second orientation comprises the first speaker facing a second direction.

6. The first playback device of claim 1 , wherein the program instructions that are executable by the at least one processor such that the first playback device is configured to play the first channel of the multi-channel audio content via the first speaker and play the second channel of the multi-channel audio content via the second speaker comprises program instructions that are executable by the at least one processor such that the first playback device is configured to (i) route the first channel of the multi-channel audio content to the first speaker and (ii) route the second channel of the multi-channel audio content to the second speaker; and
wherein the program instructions that are executable by the at least one processor such that the first playback device is configured to play the first channel of the multi-channel audio content via the second speaker and play the second channel of the multi-channel audio content via the first speaker comprises program instructions that are executable by the at least one processor such that the first playback device is configured to (i) route the second channel of the multi-channel audio content to the first speaker and (ii) route the first channel of the multi-channel audio content to the second speaker.

7. The first playback device of claim 1 , wherein the program instructions that are executable by the at least one processor such that the first playback device is configured to play the first channel of the multi-channel audio content via the first speaker and play the second channel of the multi-channel audio content via the second speaker comprises program instructions that are executable by the at least one processor such that the first playback device is configured to (i) play the first channel of the multi-channel audio content via the first speaker according to a first equalization setting and (ii) play the second channel of the multi-channel audio content via the second speaker according to a second equalization setting; and
wherein the program instructions that are executable by the at least one processor such that the first playback device is configured to play the second channel of the multi-channel audio content via the first speaker and play the first channel of the multi-channel audio content via the second speaker comprises program instructions that are executable by the at least one processor such that the first playback device is configured to (i) play the second channel of the multi-channel audio content via the first speaker according to the second equalization setting and (ii) play the first channel of the multi-channel audio content via the second speaker according to the first equalization setting.

8. The first playback device of claim 1 , wherein the first playback device comprises one of a smartphone or a tablet computer.

9. Tangible, non-transitory computer-readable media comprising program instructions that are executable by at least one processor such that a first playback device is configured to perform functions comprising:
while receiving multi-channel audio content received from a media source, determining whether the first playback device is paired with a second playback device and using at least one orientation sensor to determine an orientation of the first playback device;
while the first playback device is not paired with the second playback device and when the first playback device is determined to be in a first orientation, playing a first channel of the multi-channel audio content via a first speaker of the first playback device and playing a second channel of the multi-channel audio content via a second speaker of the first playback device;
while the first playback device is not paired with the second playback device and when the first playback device is determined to be in a second orientation, playing the first channel of the multi-channel audio content via the second speaker and playing the second channel of the multi-channel audio content via the first speaker; and
while the first playback device is paired with the second playback device regardless of orientation of the first playback device, provide the first channel of the multi-channel audio content and the second channel of the multi-channel audio content to the second playback device for playback.

10. The tangible, non-transitory computer-readable media of claim 9 , wherein the at least one orientation sensor comprises an accelerometer.

11. The tangible, non-transitory computer-readable media of claim 9 , wherein the first playback device is configured to play audiovisual content, wherein the audiovisual content comprises video content and the multi-channel audio content, and wherein the first playback device further comprises a display screen configured to display the video content of the audiovisual content.

12. The tangible, non-transitory computer-readable media of claim 9 , wherein the first orientation comprises a horizontal orientation, and wherein the second orientation comprises a vertical orientation.

13. The tangible, non-transitory computer-readable media of claim 9 , wherein the first orientation comprises the first speaker facing a first direction and the second orientation comprises the first speaker facing a seco
