Abstract

An apparatus and a method for controlling a volume in a mobile terminal are provided. The apparatus includes a motion detector and a controller. The motion detector outputs motion information from a user'"'"'s movement. The controller determines the user'"'"'s activity from the motion information output from the motion detector, and determines an appropriate output volume level responsive to the activity.

Claims

1. An apparatus for controlling a volume level of audio from an audio source, comprising:

a mobile terminal receiving the audio and outputting the audio to a speaker with a first volume level, the mobile terminal including;

a housing;

a motion detector in the housing configured to detect motion information comprising a movement velocity corresponding to a movement of the mobile terminal;

a storage unit in the housing storing in advance a plurality of predetermined volume levels corresponding respectively to a plurality of predetermined strengths of activities with continuous motion; and

a controller in the housing configured to perform determining a current strength of the current activity with continuous motion from the detected motion information, determining a second volume level of the plurality of predetermined volume levels corresponding to the current strength of the current activity with continuous motion, and determining an output volume level of the speaker by adjusting the first volume level of the audio with the second volume level corresponding to the current strength of the current activity with continuous motion.

2. The apparatus of claim 1, wherein the motion information further comprises a movement velocity corresponding to a heartbeat.

3. The apparatus of claim 1, wherein the motion detector comprises one or more detecting units configured to provide the motion information.

4. The apparatus of claim 3, wherein one of the detecting units comprises an acceleration sensor configured to provide the movement velocity as the motion information.

5. The apparatus of claim 3, wherein one of the detecting units receives a Global Positioning System (GPS) signal when a movement is detected and provides a corresponding movement velocity as the motion information.

6. The apparatus of claim 1, wherein each of the plurality of predetermined volume levels corresponding to each respective predetermined strength of the current activity is updatable.

7. The apparatus of claim 1, wherein the apparatus transfers the output volume level of the speaker via a wired line or wirelessly.

8. A method for controlling a volume level of audio from an audio source, the method comprising:

mounting a housing of a mobile terminal;

receiving the audio at the mobile terminal;

outputting the audio from the mobile terminal to a speaker with a first volume level;

storing in advance, in a storage unit in the housing, a plurality of predetermined volume levels corresponding respectively to a plurality of predetermined strengths of the activities with continuous motion;

obtaining motion information comprising a movement velocity corresponding to a movement of the mobile terminal via at least one motion detector in the housing;

determining, using a controller in the housing, a current strength of the current activity with continuous motion from the obtained motion information;

determining, using the controller, a second volume level of the plurality of predetermined volume levels corresponding to the current strength of the current activity with continuous motion; and

determining, using the controller, an output volume level of the speaker by adjusting the first volume level of the audio with the second volume level corresponding to the current strength of the current activity with continuous motion.

9. The method of claim 8, wherein the motion information further comprises a movement velocity corresponding to a heartbeat.

10. The method of claim 9, wherein the current activity is in proportion to the movement velocity and/or the heartbeat.

11. The method of claim 8, wherein the at least one motion detector is in communication with a Global Positioning System (GPS) signal.

12. The method of claim 8, wherein the at least one motion detector comprises an acceleration sensor for providing a movement velocity as the motion information.

13. The method of claim 8, wherein the mobile terminal transfers the output volume level of the speaker via a wired line or wirelessly.

14. A mobile terminal comprising:

a motion detector configured to detect motion of the mobile terminal;

a storage unit storing a plurality of predetermined volume levels corresponding respectively to a plurality of strengths of activities based on continuous motion;

a controller configured to perform determining a current strength of a current activity from the detected motion information comprising a movement velocity corresponding to a movement of the mobile terminal, and determining, based on the current strength of the current activity with continuous motion, a volume level of an receiving unit to be corresponding to the current strength of the current activity when the receiving unit is coupled to the mobile terminal.

15. The terminal of claim 14, wherein the motion information further comprises a movement velocity corresponding to a heartbeat.

16. The terminal of claim 14, wherein the motion detector comprises one or more detecting units configured to provide the motion.

17. The terminal of claim 16, wherein one of the detecting units comprises an acceleration sensor configured to provide the movement velocity as the motion of the mobile terminal.

18. The terminal of claim 16, wherein one of the detecting units receives a Global Positioning System (GPS) signal when a movement is detected and provides a corresponding movement velocity as the motion of the mobile terminal.

19. The terminal of claim 14, wherein the terminal transfers the output volume level of a speaker via a wired line or wirelessly.
