13 and 14 are rear views of a mobile terminal 200 according to an embodiment of the present invention, and FIG. 15 is a view illustrating a loop formed in the battery cover 291 according to an embodiment of the present invention. The first speaker hole 255 and the second speaker hole 256 exposed to the outside by the sliding movement of the slide module 290 is formed on both lower sides of the rear of the slide plate 250, the slide plate ( It can be seen that the lower surface of the 250 is provided with a third speaker hole 257 and the fourth speaker hole 258. The third speaker hole 257 and the fourth speaker hole 258 output sound to the lower end of the mobile terminal 200, while the first speaker hole 255 and the second speaker hole 256 is a mobile terminal ( Sound is output to both sides of the 200).

In this case, the speakers 292 and 293 are mounted inside the mobile terminal 200, as shown in FIG. In FIG. 14, a pair of speakers 292 and 293 are provided. When the first speaker 292 is disposed on the left side of FIG. 14 and the second speaker 293 is disposed on the right side, The sound output from the first speaker 292 is transmitted to the outside through the first speaker hole 255 and the third speaker hole 257, and the sound output from the second speaker 293 is the second speaker hole 256.

Accordingly, the sound leaking through the first speaker hole 255 and the second speaker hole 256 in the closed state of the mobile terminal 200 can be shielded. That is, when the sound leaks in the closed state of the mobile terminal 200, the sound output by the plurality of components provided in the mobile terminal 200 may be absorbed and the sound may be reduced. In addition, when the sound is output at a constant size, it is possible to further increase the volume of the sound propagated to the outside by reducing the sound that does not leak to the outside. The loop 295 may be made of polyoxymethylene (POM) material. As such, the loop 295 may be made of a POM material to prevent the flow of the mobile terminal 200. That is, the loop 295 may be provided not only at the position facing the first speaker hole 255 and the second speaker hole 256, but also at a portion of the upper side of the battery cover 291. If a plurality of loops 295 are formed on the inner surface of the c), the flow may be prevented by frictional force with other parts in contact with the loops 295. For example, the loop 295 shown in FIG. 15 may be in close contact with the antenna 255 (see FIG. 5) to prevent flow. 15 illustrates a rectangular loop 295, but the present invention is not limited thereto, and the shape of the loop 295 may be provided as long as it covers the first speaker hole 255 and the second speaker hole 256. Is not particularly limited.

In addition, according to an embodiment of the present invention, there may be two cameras exposed to the outside during the sliding movement.

In this way, two cameras are provided, so that three-dimensional stereoscopic images can be taken.

FIG. 17 is a schematic diagram of a stereoscopic camera module and a stereoscopic image generating process according to an embodiment of the present invention. In one embodiment of the present invention, the first camera 221 and the second camera 221a are photographed. The left eye image (L) and the right eye image (R) do not include a field of view (FOV) and image information including image information synthesized into a stereoscopic image (3D), respectively, and thus generate a 3D image (3D). It consists of a field of non-view (FON) that is removed.

The controller 180 overlaps the whole or part of the viewing area of the left eye image with the whole or part of the viewing area of the right eye image, calculates the deviation distance or the deviation angle of the overlapping viewing area, and calculates a convergence point of the stereoscopic image to be generated. Set it. Here, the convergence point is a convergence of the first camera 221 and the second camera 221a (similar to a phenomenon in which two eyes gather inward toward a subject when a person looks at a specific subject). The point where the disparity information of the two cameras becomes zero due to the shooting path of the camera 221 and the shooting path of the second camera 221a. Is a point or an area positioned on the surface of the display unit 251 (or the screen) when viewing the 3D image.

That is, the area designated as the convergence point is an area recognized by the viewer as being located on the surface of the display unit 251, such as a 2D image, and is generally referred to as a stereo window. Specifically, the unit subject located farther than the unit subject in the region designated as the convergence point when capturing the 3D image is perceived to be located behind the display unit 251 by the viewer when viewing the 3D image, and conversely, The unit subject positioned closer to the unit subject in the region designated as the convergence point when capturing the image 3D is recognized as being positioned in front of the display unit 251 to the observer when the 3D image is viewed.

Thereafter, the controller 180 overlaps the field of view of the left eye image and the field of view of the right eye image based on a point or region designated as a convergence point, and then the non-overlapping field of view of the field of view of the left eye image and the field of view of the right eye image. To generate a stereoscopic image.
