Abstract

Claims (40)

1. A computer-implemented method comprising program instructions stored on a carrier medium, the method comprising:

first program instructions executable by a processor for determining an orientation of a display of a portable system having a maximum of two speakers; and

second program instructions executable by the processor for altering an orientation of the two speakers arranged along one side of the system based on the orientation of the display, wherein the orientation of the two speakers is altered by swapping audio signals supplied to the two speakers when the orientation of the display is rotated clockwise 90° from a portrait orientation to a landscape orientation or counter-clockwise 90° from the landscape orientation to the portrait orientation.

2. The method of claim 1 , wherein the two speakers are internal speakers of the portable system.

3. The method of claim 1 , wherein the two speakers are not external speakers of the portable system, and wherein an orientation of the external speakers remains unchanged regardless of the orientation of the display.

4. The method of claim 1 , wherein the portable system performs the computer-implemented method automatically.

5. The method of claim 1 , wherein the portable system performs the computer-implemented method upon receipt of input entered manually by a user.

6. The method of claim 1 , wherein the portable system performs the computer-implemented method upon detecting that the portable system has been placed into a docking station.

7. The method of claim 1 , wherein the orientation of the two speakers maintains a correct stereo base for the orientation of the display.

8. The method of claim 1 , wherein the portable system comprises a tablet personal computer.

9. The method of claim 1 , wherein the orientation of the two speakers is altered by swapping audio signals supplied to the two speakers when the orientation of the display is rotated 180°.

10. The method of claim 1 , wherein the orientation of the two speakers is not altered when the orientation of the display is rotated counter-clockwise 90° from a portrait orientation to a landscape orientation or clockwise 90° from a landscape orientation to a portrait orientation.

11. A computer-implemented method comprising program instructions stored on a carrier medium, the method comprising:

first program instructions executable by a processor for determining an orientation of a display of a portable system having a maximum of two speakers, wherein the two speakers are arranged along one side of the portable system;

second program instructions executable by the processor for determining an orientation of the two speakers of the system based on the orientation of the display; and

third program instructions executable by the processor for determining if a current orientation of the two speakers differs from the determined orientation of the two speakers, and if so, altering the current orientation of the two speakers such that the two speakers have the determined orientation, wherein said altering comprises swapping audio signals supplied to the two speakers when the orientation of the display is rotated clockwise 90° from a portrait mode to a landscape mode or counter-clockwise 90° from the landscape mode to the portrait mode.

12. The method of claim 11 , wherein the determined orientation of the two speakers corresponds to a correct stereo base for the orientation of the display.

13. The method of claim 11 , wherein the two speakers are internal speakers of the portable system.

14. The method of claim 11 , wherein the two speakers are not external speakers of the portable system, and wherein an orientation of the external speakers remains unchanged regardless of the orientation of the display.

15. The method of claim 11 , wherein the orientation of the two speakers is altered by swapping audio signals supplied to the two speakers when the orientation of the display is rotated 180°.

16. The method of claim 11 , wherein the orientation of the two speakers is not altered when the orientation of the display is rotated counter-clockwise 90° from a portrait orientation to a landscape orientation or clockwise 90° from a landscape orientation to a portrait orientation.

17. A portable system, comprising:

means for determining an orientation of a display of the portable system having a maximum of two speakers arranged along one side of the portable system; and

means for altering an orientation of the two speakers arranged along one side of the portable system based on the orientation of the display, wherein said altering comprises swapping audio signals supplied to the two speakers when the orientation of the display is rotated clockwise 90° from a portrait orientation to a landscape orientation or counter-clockwise from the landscape orientation to the portrait orientation.

18. The portable system of claim 17 , wherein the orientation of the two speakers provides a correct stereo base for the orientation of the display.

19. The portable system of claim 17 , wherein the two speakers are not external speakers of the portable system, and wherein an orientation of the external speakers remains unchanged regardless of the orientation of the display.

20. The portable system of claim 17 , wherein the means for determining the orientation of the display comprises means for detecting input entered manually by a user indicating the orientation of the display.

21. The portable system of claim 17 , wherein the means for determining the orientation of the display comprises means for detecting that the portable system has been placed into a docking station and means for determining a position of the portable system in the docking station.

22. The portable system of claim 17 , wherein the portable system comprises a tablet personal computer.

23. The portable system of claim 17 , wherein the portable system further comprises:

left and right audio inputs for generating left and right audio signals; and

left and right amplifiers for amplifying the left and right audio signals.

24. The portable system of claim 23 , wherein the left audio input is coupled to the left amplifier, wherein the right audio input is coupled to the right amplifier, and wherein the means for altering the orientation of the two speakers is coupled between the amplifiers and the speakers for altering which amplifier is coupled to which speaker.

25. The portable system of claim 23 , wherein the left amplifier is coupled to a first one of the two speakers, wherein the right amplifier is coupled to a second one of the two speakers, and wherein the means for altering the orientation of the two speakers is coupled between the amplifiers and the audio inputs for altering which audio input is coupled to which amplifier.

26. The portable system of claim 17 , wherein the orientation of the two speakers is altered by swapping audio signals supplied to the two speakers when the orientation of the display is rotated 180°.

27. The portable system of claim 17 , wherein the orientation of the two speakers is not altered when the orientation of the display is rotated counter-clockwise 90° from a portrait orientation to a landscape orientation or clockwise 90° from a landscape orientation to a portrait orientation.

28. The portable system of claim 17 , wherein the two speakers arranged along one side of the portable system are located on the front of the portable system, wherein the portable system further comprises:

two additional speakers located on the back of the portable system;

means for detecting an orientation of a user of the portable system; and

means for altering an orientation of the front and back speakers based on the orientation of the user.
