Abstract

A method for controlling speakers in a mobile station comprises detecting a movement of the mobile station. The method also comprises differentially controlling sound output by the speakers based on the detected movement of the mobile station. The differentially controlling the sound output by the speakers based on the detected movement of the mobile station may comprise at least one of adjusting a sound volume and selecting a sound effect. The detecting the movement of the mobile station may comprise detecting a tilt of the mobile station.

Claims

1. A method for controlling speakers in a mobile station, the method comprising:

detecting a movement of the mobile station; and

differentially controlling sound output by the speakers based on the detected movement of the mobile station.

2. The method of claim 1, wherein the differentially controlling the sound output by the speakers based on the detected movement of the mobile station comprises at least one of adjusting a sound volume and selecting a sound effect.

3. The method of claim 1, wherein the detecting the movement of the mobile station comprises detecting a tilt of the mobile station.

4. The method of claim 1, wherein the differentially controlling the sound output by the speakers based on the detected movement of the mobile station comprises:

selecting a volume level based on the detected movement of the mobile station;

controlling sound signals based on the selected volume level; and

outputting the controlled sound signals to the speakers.

5. The method of claim 4, wherein the sound signals comprise at least one of voice signals and acoustic signals.

6. The method of claim 1, further comprising:

adjusting animation displayed on the mobile station based on the detected movement of the mobile station.

7. A method for controlling audio-visual output in a mobile station, the method comprising:

detecting a movement of the mobile station;

differentially controlling sound output by mobile station speakers based on the detected movement of the mobile station; and

adjusting animation displayed on the mobile station based on the detected movement of the mobile station.

8. The method of claim 7, wherein the detecting the movement of the mobile station comprises detecting a tilt of the mobile station.

9. The method of claim 7, wherein the differentially controlling the sound output by the mobile station speakers based on the detected movement of the mobile station comprises:

selecting a volume level based on the detected movement of the mobile station;

controlling sound signals based on the selected volume level; and

outputting the controlled sound signals to the mobile station speakers.

10. The method of claim 9, wherein the sound signals comprise at least one of voice signals and acoustic signals.

11. A control apparatus adapted to control speakers in a mobile station, the control apparatus comprising:

a tilt sensor adapted to detect a tilt of the mobile station;

a volume selecting unit operatively coupled to the tilt sensor, adapted to select a volume level based on the detected tilt and to output the volume level;

a sound signal generating unit adapted to generate sound signals; and

a volume controlling unit operatively coupled to the volume selecting unit and the sound signal generating unit, adapted to differentially control the sound signals generated by the sound signal generating unit based on the volume level outputted from the volume selecting unit.

12. The control apparatus of claim 11, further comprising speakers operatively coupled to the volume controlling unit, adapted to output the differentially controlled sound signals from the volume controlling unit.

13. The control apparatus of claim 12, wherein the speakers are respectively positioned at right and left sides of a hinge portion on the mobile station.

14. The control apparatus of claim 12, wherein the speakers are stereo speakers.

15. The control apparatus of claim 11, wherein the volume controlling unit comprises a voltage controlling amplifier.

16. The control apparatus of claim 11, wherein the tilt sensor comprises a position detecting sensor.

17. The control apparatus of claim 11, wherein the volume selecting unit stores volume levels associated with various tilts of the mobile station.

18. The control apparatus of claim 11, wherein the sound signals generated by the sound signal generating unit comprise at least one of voice signals and acoustic signals.
