Abstract

A loudspeaker system can have first and second loudspeakers selectively operable in a single-channel mode or in a multi-channel mode. In the single-channel mode, the first and the second loudspeakers are configured to simultaneously reproduce a substantially identical signal. In the multi-channel mode, the first loudspeaker reproduces a first-channel signal and the second loudspeaker reproduces a second-channel signal. The first-channel signal and the second-channel signal can constitute respective portions of a multi-channel signal. Such loudspeaker systems can also have a mode selector configured to select one of the single-channel mode and the multi-channel mode. In some embodiments, such selection can occur in response to one or more detected proximities of another loudspeaker system. Multi-zone loudspeaker systems are also disclosed.

Claims

1. An automatically configurable audio appliance comprising a processor, a memory, and one or more communication connections, wherein the memory stores instructions that, when executed by the processor, cause the audio appliance to:

establish a first wireless communication connection with a second appliance;

over the first wireless communication connection, wirelessly transmit a first configuration information to the second appliance and wirelessly receive a second configuration information from the second appliance;

select a single-channel mode of operation or a multi-channel mode of operation;

establish a second wireless communication connection responsive to the first configuration information, the second configuration information, or a combination thereof;

wirelessly receive media information over the second wireless communication connection; and

playback a selected portion of the media information in correspondence with the selected mode of operation.

2. The automatically configurable audio appliance according to claim 1, wherein the second appliance comprises a second audio appliance, wherein the media information is received from the other second audio appliance.

3. The automatically configurable audio appliance according to claim 1, wherein the second appliance comprises a media player, wherein the media information is received from the media player.

4. The automatically configurable audio appliance according to claim 1, wherein the second appliance comprises a second audio appliance, and wherein the instructions, when executed by the processor, further cause the audio appliance to establish wireless communication with a media player, wherein the media information is received from the media player.

5. The automatically configurable audio appliance according to claim 1, wherein the second-appliance comprises a second audio appliance, wherein the selected portion of the media information comprises a first selected portion, wherein the instructions, when executed by the processor, further cause the audio appliance to transmit a second selected portion of the media information to the other second audio appliance.

6. The automatically configurable audio appliance according to claim 5, wherein the second selected portion of the media information corresponds to the selected mode of operation.

7. The automatically configurable audio appliance according to claim 5, wherein the second selected portion of the media information is different from the first selected portion of the media information.

8. The automatically configurable audio appliance according to claim 5, wherein the second selected portion of the media information and the first selected portion of the media information are the same as each other.

9. The automatically configurable audio appliance according to claim 5, wherein the instructions, when executed by the processor, cause the audio appliance to playback the first selected portion of the media information synchronously with playback of the second selected portion of the media information by the second audio appliance.

10. The automatically configurable audio appliance according to claim 5, wherein the first selected portion of the media information is played back in a first playback zone and the second selected portion of the media information is played back in a second playback zone.

11. The automatically configurable audio appliance according to claim 1, wherein the instructions, when executed by the processor, cause the audio appliance to further select a single-zone mode of operation or a multi-zone mode of operation.

12. The automatically configurable audio appliance according to claim 1, further comprising at least one loudspeaker transducer, wherein the instructions, when executed by the processor, cause the audio appliance to playback the selected portion of the media information through the at least one loudspeaker transducer.

13. A configurable audio appliance comprising a processor, a memory, a plurality of loudspeaker transducers, and one or more communication connections, wherein the memory stores instructions that, when executed by the processor, cause the audio appliance to:

establish a first wireless communication connection with a second appliance;

over the first wireless communication connection, wirelessly exchange, with the second appliance, configuration information associated with a second wireless communication connection with the second appliance;

select a single-channel mode of operation or a multi-channel mode of operation responsive, at least in part, to a configuration information received from the second appliance;

establish the second wireless communication connection with the second appliance;

wirelessly receive multi-channel media information over the second wireless communication connection; and

playback a selected portion of the multi-channel media information over the plurality of loudspeaker transducers in correspondence with the selected mode of operation.

14. The configurable audio appliance according to claim 13, wherein the second appliance is a second audio appliance.

15. The configurable audio appliance according to claim 13, the second audio appliance is a media player.

16. The configurable audio appliance according to claim 13, wherein the selected portion of the multi-channel media information comprises a first portion of the multi-channel media information, wherein the instructions, when executed by the processor, cause the audio appliance to transmit a second portion of the multi-channel media information to the second appliance in correspondence with the selected mode of operation, wherein the second portion of the multi-channel media information is identical to or different from the first portion of the multi-channel media information.

17. The configurable audio appliance according to claim 13, wherein the instructions, when executed by the processor, cause the audio appliance to select a single-zone mode of operation or a multi-zone mode of operation responsive, at least in part, to configuration information received from the second appliance.

18. An automatically configurable audio appliance comprising a processor, a memory, and one or more communication connections, wherein the memory stores instructions that, when executed by the processor, cause the audio appliance to:

establish a first wireless communication connection with a second appliance;

over the first wireless communication connection, wirelessly transmit a first configuration information to the second appliance and wirelessly receive a second configuration information from the second appliance;

select a single-zone mode of operation or a multi-zone mode of operation;

configure a second wireless communication connection responsive to the first configuration information, the second configuration information, or a combination thereof;

wirelessly receive media information over the second wireless communication connection; and

playback a selected portion of the media information in correspondence with the selected mode of operation.

19. The configurable audio appliance according to claim 18, wherein the selected portion of the multi-channel media information comprises a first portion of the multi-channel media information, wherein the instructions, when executed by the processor, cause the audio appliance to transmit a second portion of the multi-channel media information to the second appliance in correspondence with the selected mode of operation, wherein the second portion of the multi-channel media information is identical to or different from the first portion of the multi-channel media information.

20. The automatically configurable audio appliance according to claim 18, wherein the instructions, when executed by the processor, cause the audio appliance to select a single-channel mode of operation or a multi-channel mode of operation responsive to the first configuration information, the second configuration information, or a combination thereof.
