Abstract

A hand-held wireless communications device operates in a communications mode and a stereo mode. The device comprises a housing, a long-range transceiver within the housing to communicate with a base station in the communications mode, and a receiver within the housing to receive radio signals from a broadcast radio station when the device is in the stereo mode. The broadcast radio station may transmit, for example, AM or FM signals to the and-held device. A controller within the housing generates control signals to place the device in the communications mode and the stereo mode, and selectively controls a plurality of speakers to render audio signals as audible sound. The plurality of speakers includes a pair of longitudinally-spaced speakers disposed opposite each other on the housing of the hand-held device.

Claims

1. A method of rendering audible sound to a user of a hand-held wireless communications device, the method comprising:

receiving, in a communications mode, communication signals from a base station in a wireless communications network on a long-range transceiver disposed in a housing of a hand-held wireless communications device;

receiving, in a stereo mode, radio signals from a broadcast radio station on a receiver disposed in the housing of the hand-held wireless communications device;

selective enabling first and second longitudinally-spaced speakers disposed in the housing at opposite ends of the hand-held wireless communications device to render the received radio signals as audible sound when the hand-held device is in the stereo mode;

selectively enabling third and fourth speakers disposed in the housing of the hand-held wireless communications device when the hand-held device is in the stereo mode, and rendering the radio signals through the enabled speakers as stereo sound;

disabling the second speaker when the hand-held wireless communications device is in the communications mode, the second speaker being disposed proximate a microphone;

sampling the received radio signals; and

balancing a load on the first, second, third, and fourth speakers based on the sampled signals when the device is in the stereo mode.

2. The method of claim 1 further comprising generating a control signal to place the hand-held device in the communications mode.

3. The method of claim 2 wherein the control signal is generated responsive to user input.

4. The method of claim 2 wherein the control signal is generated responsive to detecting an incoming call.

5. The method of claim 1 further comprising generating a control signal to place the hand-held device in the stereo mode.

6. The method of claim 5 wherein the control signal is generated responsive to the selection of a frequency associated with the broadcast radio station.

7. The method of claim 1 further comprising rendering the radio signals through the first and second speakers as stereo sound.

8. The method of claim 1 wherein the first and second speakers render low frequency sound, and the third and fourth speakers render high frequency sound.

9. The method of claim 1 further comprising displaying a graphical representation of a load on one or more of the first, second, third, and fourth speakers when the hand-held device is in the stereo mode.

10. The method of claim 1 further comprising extending a display connected to the hand-held wireless communications device from a retracted position to an extended position.

11. A hand-held wireless communications device comprising:

a housing that includes;

communication circuitry to communicate with one or more base stations in a wireless communications network;

stereo circuitry to receive radio signals from a broadcast radio station;

a first pair of longitudinally-spaced speakers to render the received radio signals as stereo sound to a user;

a second pair of longitudinally-spaced speakers; and

a display movable between a retracted position and an extended position, wherein the display is positioned between each speaker in the first pair of speakers when the display is in the retracted position.

12. The hand-held wireless communications device of claim 11 further comprising:

a microphone in the housing; and

a controller configured to;

sample the received radio signals; and

balance a load on the first and second pairs of longitudinally-spaced speakers based on the sampled signals when the device is in a stereo mode.

13. The hand-held device of claim 12 wherein the controller is further configured to generate a first control signal to switch the hand-held communications device between a communications mode and the stereo mode.

14. The hand-held device of claim 13 wherein the controller generates the first control signal responsive to user input.

15. The hand-held device of claim 13 wherein the controller automatically generates the first control signal responsive to detecting an incoming call.

16. The hand-held device of claim 13 wherein the stereo circuitry comprises a tuner, and wherein the controller generates a second control signal to tune the tuner to a radio frequency associated with the selected broadcast radio station.

17. The hand-held device of claim 16 further comprising memory within the housing to store the frequency associated with the selected broadcast radio station.

18. The hand-held device of claim 13 wherein the controller is configured to enable and disable selected ones of the first and second pairs of longitudinally-spaced speakers based on whether the hand-held device is in the communications mode or the stereo mode.

19. The hand-held device of claim 13 wherein the display displays the image of one or more remote parties when the hand-held device is in the communications mode.

20. The hand-held device of claim 13 wherein one speaker in the first pair of longitudinally-spaced speakers is enabled and the other speaker in the first pair of longitudinally-spaced speakers is disabled when the hand-held device is in the communications mode.

21. The hand-held device of claim 12 wherein the controller is further configured to:

generate equalization information for display to the user based on the sampled signals; and

balance the load on the first and second pairs of longitudinally-spaced speakers based on the equalization information responsive to user input.

22. The hand-held device of claim 12 wherein the display displays a graphical representation of the load on the first and second pairs of longitudinally-spaced speakers when the hand-held device is in the stereo mode.

23. The hand-held device of claim 12 wherein the first pair of longitudinally-spaced speakers produces low frequency sound.

24. The hand-held device of claim 23 wherein the second pair of speakers produces high frequency sound.

25. The hand-held device of claim 12 wherein the first and second pairs of longitudinally-spaced speakers are enabled to produce stereo sound.

26. The hand-held device of claim 11 wherein the display attaches to the housing via one or more rotatable hinges.

27. The hand-held device of claim 11 wherein the display comprises one or more telescoping legs that permit a user to adjust the height of the display when the display is in the extended position.

28. The device of claim 11 further comprising a handle attached to the housing.
