At this time, a through hole 250b may be formed at a portion of the slide plate 250 where the roller 245 is engaged, such that the roller 245 has a stroke enough to slide the slide.

Meanwhile, in one embodiment of the present invention, four sound output holes 255, 256, 257 and 258 may be provided, which will be described with reference to FIG. 13 to FIG.

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 showing a loop formed in a battery cover 291 according to an embodiment of the present invention, A first speaker hole 255 and a second speaker hole 256 which are exposed to the outside by sliding movement of the slide module 290 are formed on both lower sides of the rear surface of the slide plate 250, 250 are provided with a third speaker hole 257 and a fourth speaker hole 258 on the lower surface thereof. 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 output sound to the mobile terminal 200 200).

At this time, the speakers 292 and 293 are mounted inside the mobile terminal 200 as shown in FIG. 14 shows a pair of loudspeakers 292 and 293. In the case where the first speaker 292 is disposed on the left side of FIG. 14 and the second speaker 293 is disposed on the right side of FIG. 14, 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 transmitted through the second speaker hole 256 And the fourth speaker hole 258 through the fourth speaker hole 258.

When the mobile terminal 200 is opened by the sliding movement, the first speaker hole 255 and the second speaker hole 256 exposed at the rear surface of the mobile terminal 200, Sound can be propagated through the third speaker hole 257 and the fourth speaker hole 258 formed at the lower end of the speaker 200 to obtain a stereo sound effect.

15, a battery cover 291 is formed on the rear surface of the slide plate 250. The first speaker hole 255 and the second speaker hole 256 of the battery cover 291, And a loop 295 (loop) protruding to the opposite position is formed. Accordingly, the sound leaking through the first speaker hole 255 and the second speaker hole 256 can be shielded in a state where the mobile terminal 200 is closed. That is, when sound is leaked in a state where the mobile terminal 200 is closed, the sound output by the plurality of parts provided inside the mobile terminal 200 is absorbed, so that the sound can be reduced. In addition, when sound is output at a constant size, it is possible to further increase the size of the sound propagated to the outside by reducing the sound that can not leak to the outside. The loop 295 may be made of POM (poly oxy methylene). Thus, the loop 295 is made of a POM material to prevent the mobile terminal 200 from flowing. 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 part of the upper part of the battery cover 291, The flow can be prevented by the frictional force with other parts in contact with the loop 295. [ For example, the loop 295 shown in Fig. 15 can be brought into close contact with the antenna 255 (see Fig. 5) to prevent the flow. 15 shows a rectangular loop 295, the present invention is not limited to this. The shape of the loop 295 may be a shape that can cover the first speaker hole 255 and the second speaker hole 256, Is not particularly limited.

Also, according to an embodiment of the present invention, there may be two cameras which are exposed to the outside during sliding movement. That is, as shown in FIG. 5, the first camera 221 is provided on the printed circuit board 260, and the second camera 221a, which is exposed to the outside during the sliding movement, May be provided.

Thus, two cameras are provided, so that three-dimensional stereoscopic images can be photographed.

17 is a schematic diagram of a stereoscopic image camera module and a stereoscopic image generation process according to an embodiment of the present invention. In an embodiment of the present invention, the first camera 221 and the second camera 221a photograph The left eye image L and the right eye image R do not include the field of view (FOV) including the image information synthesized in the stereoscopic image 3D and the image information, And a field of non-view (FON) to be removed.

The control unit 180 calculates the deviation distance or the deviation angle of the overlapping view area by superimposing all or a part of the view area of the left eye image and the entire view area of the right eye image to calculate the convergence point of the stereoscopic image to be generated Setting. The convergence point is a convergence of convergence of the first camera 221 and the second camera 221a when convergence of the first camera 221 and the second camera 221a occurs, Refers to a specific point at which the parallax information of the two cameras becomes 0 due to the phenomenon that the photographing path of the camera 221 and the photographing path of the second camera 221a converge toward the subject). The point or area designated as the convergence point Is a point or an area located on the surface of the display unit 251 (or screen) when viewing a stereoscopic image (3D).

That is, the area designated as the convergence point is an area recognized by the observer, which is located on the surface of the display part 251 like a 2D image, and is generally referred to as a stereowindow. Specifically, it is recognized that a unitary object positioned farther away from a unitary object in an area designated as a convergence point when capturing the 3D image is positioned behind the display unit 251 to the observer when viewing the 3D image (3D) A unitary object positioned closer to a unitary object in an area designated as a convergence point at the time of shooting a 3D image is recognized as being located in front of the display unit 251 to an observer when viewing a stereoscopic image (3D).

Then, the control unit 180 superimposes the field of view of the left eye image and the field of view of the right eye image on the basis of the point or area designated as the convergence point, To generate a stereoscopic image.
