Abstract

A wireless audio system includes a host, a transmitter, and a receiver. The host includes a controller for controlling operations of the host, application software executed by the controller for producing audio signals, and a first electrical connector for connecting to a second electrical connector of the transmitter. The transmitter includes a first transceiver for wirelessly transmitting audio signals received from the host and for wirelessly transmitting and receiving data. The receiver includes a second transceiver for receiving audio signals wirelessly transmitted from the first transceiver of the transmitter, an audio output device for outputting the received audio signals, and a user interface for receiving a command from a user for controlling the host. The command is wirelessly transmitted from the receiver to the transmitter and delivered to the host, and the application software performs an action according to the command.

Claims

1. A wireless audio system, comprising:

a host, comprising;

a controller for controlling operations of the host;

application software executed by the controller for producing audio signals; and

a first electrical connector;

a transmitter, comprising;

a second electrical connector for connecting to the first electrical connector of the host, receiving audio signals from the host, and exchanging data with the host; and

a first transceiver for wirelessly transmitting the audio signals received from the host and for wirelessly transmitting and receiving data; and

a receiver, comprising;

a second transceiver for receiving audio signals wirelessly transmitted from the first transceiver of the transmitter;

an audio output device for outputting the received audio signals; and

a user interface for receiving a command from a user for controlling the host, wherein the command is wirelessly transmitted to the transmitter through the first and second transceivers, the transmitter sends the command to the application software of the host through the first and second electrical connectors, and the application software performs an action according to the command.

2. The system of claim 1, wherein the first and second electrical connectors are universal serial bus (USB) connectors.

3. The system of claim 1, wherein the audio output device is an amplifier.

4. The system of claim 1, wherein the audio output device is a speaker.

5. The system of claim 1, wherein the audio output device is an earphone jack.

6. The system of claim 1, wherein the user interface of the receiver comprises a display.

7. The system of claim 6, wherein while transmitting audio signals to the receiver through the transmitter, the application software also transmits related data that is shown on the display of the receiver.

8. The system of claim 1, wherein the user interface of the receiver comprises a push button or a tact switch with tactile feedback for allowing the user to generate commands for controlling the host.

9. The system of claim 1, wherein the receiver further comprises:

a microphone for receiving voice input from the user; and

an analog-to-digital converter for converting the voice input into digital voice signals for wirelessly transmitting the digital voice signals to the transmitter through the first and second transceivers; and

the transmitter further comprises;

a digital-to-analog converter for converting received digital voice signals into analog voice signals; and

a speaker for producing sound from the analog voice signals.

10. The system of claim 1, wherein the receiver further comprises:

a microphone for receiving voice input from the user; and

an analog-to-digital converter for converting the voice input into digital voice signals for wirelessly transmitting the digital voice signals to the transmitter through the first and second transceivers; and

the transmitter further comprises a digital audio output port for outputting the digital voice signals.

11. A wireless audio system, comprising:

a host, comprising;

a controller for controlling operations of the host; and

a first electrical connector;

a transmitter, comprising;

a second electrical connector for connecting to the first electrical connector of the host, receiving audio signals from the host, and exchanging data with the host;

a first transceiver for wirelessly transmitting the audio signals received from the host and for wirelessly transmitting and receiving data; and

a sound output device; and

a receiver, comprising;

a second transceiver for receiving audio signals wirelessly transmitted from the first transceiver of the transmitter;

an audio output device for outputting the received audio signals;

a microphone for receiving voice input from the user; and

an analog-to-digital converter for converting the voice input into digital voice signals for wirelessly transmitting the digital voice signals to the transmitter through the first and second transceivers for outputting the digital voice signals through the sound output device of the transmitter.

12. The system of claim 11, wherein the transmitter further comprises:

a digital-to-analog converter for converting received digital voice signals into analog voice signals; and

the sound output device is a speaker for producing sound from the analog voice signals.

13. The system of claim 11, wherein the sound output device of the transmitter is a digital audio output port for outputting the digital voice signals.
