This will be described in more detail as follows.

The first and second multimedia source playback units S1 and S2 may be located in the playback area of the web page P. FIG. In the web page P according to the present embodiment, it can be seen that the first and second multimedia source playback units S1 and S2 are adjacent to each other. The volume weighting reference position G may be provided at a specific place in the reproduction area A by the user's manipulation or the operation of the controller 180 of FIG. 1. In the present embodiment, the volume weighting reference position (G) is set in the form of a line at the interruption of the playback area, but the position where the volume weighting reference position (G) is set is not limited thereto, and the volume weighting reference position is not limited thereto. Of course, (G) may be a specific area that can be displayed in various shapes such as squares, triangles, circles, and the like.

The controller (180 in FIG. 1) measures the distance between the volume weighting reference position G and the first and second multimedia source playback units S1 and S2.

As shown in FIG. 6, the first distance L1 between the first multimedia source playback unit S1 and the volume weighting reference position G is the second multimedia source playback unit S2 and the volume weighting reference position G. As shown in FIG. It can be seen that less than the second distance (L2) of the liver.

The controller 180 of FIG. 1 may adjust the volume of the first multimedia source playback unit S1 closest to the volume weighting reference position G to be greater than the volume of the second multimedia source playback unit S2. If the volume of the first multimedia source playback unit S1 is significantly higher than that of the second multimedia source playback unit S2, the second volume may be increased by the volume of the first multimedia source playback unit S1 that is relatively large even if the sound is somewhat overlapped. The sound generated from the multimedia source playback unit S2 can be ignored, resulting in a lower possibility of operator confusion. In addition, the second multimedia source playback unit S2 visually present in the playback area A can also be intuitively recognized as operating even though the volume is small, so that the failure of the mobile terminal 100a is not suspected.

As illustrated in FIG. 7, the scroll 181 may be moved by a user's manipulation or the like. As the scroll 181 is operated, the web page P is moved, and thus the portion displayed through the reproduction area A is moved. By moving the screen, the third distance L3 between the first multimedia source playback unit S1 and the volume weighting reference position G is between the second multimedia source playback unit S2 and the volume weighting reference position G. It is far away from the fourth distance (L4) of. Therefore, the controller 180 of FIG. 1 increases the volume of the second multimedia source player S2 instead of reducing the volume of the first multimedia source player S1.

The distance between the volume weighting reference position G and the first and second multimedia source playback units S1 and S2 is linearly moved away from or close to each other by the operation of the scroll 181. Therefore, according to the second embodiment of the present invention, the volume between the first and second multimedia source playback units S1 and S2 gradually increases or decreases as the scroll 181 moves, so that the operator feels emotional satisfaction. Possible effects additionally occur.

8A and 8B are flowcharts of the mobile terminal of FIGS. 6 and 7.

As shown in the figure, the mobile terminal according to the second embodiment of the present invention is different from the mobile terminal according to the first embodiment of the present invention in step S40a of adjusting the playback volume of the multimedia source player. The step (S40a) of adjusting the playback volume of the multimedia source playback unit will be described in detail with reference to FIG. 8B.

As shown in FIG. 8B, it is determined whether the multimedia source playback unit is located inside the playback area (S42).

If the multimedia source player is not located inside the playback area, the multimedia source player is deactivated (S46).

When the multimedia source player is located inside the playback area, the distance between the volume weighting reference position and the multimedia source player is calculated (S43).

When the distance between the volume weighting reference position and the multimedia source player is calculated, the playback volume is increased as the distance between the volume weighting position and the multimedia source player is closer (S45). That is, the volume of the multimedia source playback unit closest to the volume-weighted reference position is maximized, and when the distance from the volume-weighted reference position is farther away, the volume is gradually reduced to improve the operator's feeling and improve the emotional quality.
