Abstract

An audio device connects multiple audio sources to speakers. The audio device has an audio input for receiving the output of a wireless receiver, an audio channel including an amplifier that processes the audio input to provide an audio signal that is directed to the speakers. The audio channel also can include a digital-to-analog converter and/or line level switch. The line level switch enables the audio device to direct either the audio from a line level input or the wireless audio device to the speakers. The audio device can have a housing, which has a recess that receives the wireless audio device. In the recess, a receptacle is located to connect to a power plug of a wireless receiver. Another connector is located in the recess to connect the audio output of the wireless receiver to the audio input of the audio device.

Claims

1. An audio device comprising:

an audio input for receiving an audio output from a wireless receiver, wherein the wireless receiver can be connected to receive audio data wirelessly from an audio source and play received audio to the audio output;

an audio channel that processes the audio input to provide an audio signal; and

connectors connected to the audio signal;

wherein the connectors are configured to connect to speakers.

2. The audio device of claim 1, wherein the audio channel comprises an amplifier.

3. The audio device of claim 2, wherein the audio channel further includes a digital-to-analog converter.

4. The audio device of claim 2, wherein the audio channel further includes a line level switch.

5. The audio device of claim 4, wherein the line level switch has a first input connected to receive an audio signal originating from the audio output of the wireless receiver and a second input connected to a line level input.

6. The audio device of claim 1, further comprising a housing having an external surface, on which audio connectors are mounted for connection to the audio output of the wireless receiver, and on which speaker connectors are mounted for connection to speakers.

7. The audio device of claim 6, wherein the housing further comprises line level connectors mounted on an external surface for connection to a line level input.

8. The audio device of claim 6, wherein the housing has a recess that receives the wireless receiver.

9. The audio device of claim 8, wherein the recess has an external surface on which a receptacle is located to connect to a power plug of the wireless receiver.

10. The audio device of claim 8, wherein the connector that connects to the audio output of the wireless receiver is mounted in the recess.

11. A audio system comprising:

a wireless receiver having an audio output;

a plurality of audio sources that transmit audio data wirelessly to the wireless receiver;

wherein the wireless receiver can be connected to receive audio data wirelessly from a selected one of the audio sources and play received audio to the audio output;

an audio device comprising;

an audio input for receiving the audio output from the wireless receiver,

an audio channel that processes the audio input to provide an audio signal, and

connectors connected to the audio signal; and

speakers connected to the connectors.

12. The audio system of claim 11, wherein the audio channel comprises an amplifier.

13. The audio system of claim 12, wherein the audio channel further includes a digital-to-analog converter.

14. The audio system of claim 12, wherein the audio channel further includes a line level switch.

15. The audio system of claim 14, wherein the line level switch has a first input connected to receive an audio signal originating from the audio output of the wireless receiver and a second input connected to a line level input.

16. The audio system of claim 11, wherein the audio device further comprises a housing having an external surface, on which audio connectors are mounted for connection to the audio output of the wireless receiver, and on which speaker connectors are mounted for connection to speakers.

17. The audio system of claim 16, wherein the housing further comprises line level connectors mounted on an external surface for connection to a line level input.

18. The audio system of claim 16, wherein the housing has a recess that receives the wireless receiver.

19. The audio system of claim 18, wherein the recess has an external surface on which a receptacle is located to connect to a power plug of the wireless receiver.

20. The audio system of claim 18, wherein the connector that connects to the audio output of the wireless receiver is mounted in the recess.
