The camera 121 'may have a photographing direction substantially opposite to that of the camera 121 (see FIG. 1), and may be a camera having the same or different pixels as the camera 121.

For example, the camera 121 may have a low pixel so that the face of the user can be photographed and transmitted to the other party in case of a video call or the like, and the camera 121 ' It is preferable to have a large number of pixels. The cameras 121 and 121 'may be installed in the terminal body such that they can be rotated or pop-up.

A flash 123 and a mirror 124 may be additionally disposed adjacent to the camera 121 '. The flash 123 illuminates the subject when the subject is photographed by the camera 121 '. The mirror 124 allows the user to illuminate the user's own face or the like when the user intends to shoot himself / herself (self-photographing) using the camera 121 '.

The microphone 122 receives an external sound signal through a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 when the voice data is in the call mode, and output. Various noise reduction algorithms may be implemented in the microphone 122 to remove noise generated in receiving an external sound signal.

The user input unit 130 is operated to receive a command for controlling the operation of the mobile terminal 100. The user input unit 130 includes a key 134 input by a command when a user touches the touch sensor, And may include buttons 131, 132, and 133 of an inputting method. The user input units 131, 132, and 133 may also be collectively referred to as a manipulating portion.

The antenna 116, which forms part of the broadcast receiving module 111 (see FIG. 1), can be installed to be able to be drawn out from the terminal body.

3 is a perspective view of a speaker grill 200 of a mobile terminal according to an embodiment of the present invention, Figure 4 is a cross-sectional view showing a speaker grill 200 of a mobile terminal according to an embodiment of the present invention. Hereinafter, the structure of the sound output unit 152 'will be described in detail with reference to FIGS. 3 and 4.

The sound output unit 152 ′ of the present invention includes a speaker module 250, a speaker hole 102c, and a speaker grille 200, 200.

The speaker hole 102c is formed in the case of the mobile terminal and is not necessarily limited to that formed in the rear case. The speaker hole 102c may be formed on the side surface or may be formed on the battery cover. 4 illustrates a speaker hole 102c formed in the rear case 102 of a battery-matching mobile terminal.

The speaker hole 102c has a speaker module 250 for outputting sound therein, and provides a passage through which the sound output from the speaker module 250 can escape to the outside of the mobile terminal case. However, when the surface on which the speaker hole 102c is formed faces the mounting surface, there is a problem that the sound is not output smoothly due to the speaker hole 102c being blocked.

The speaker hole 102c formed on the rear surface may secure a passage by forming irregularities in the case so that the entire rear surface of the speaker hole 102c is not in close contact with the bottom surface. However, if the surface of the case is made of a glass material rather than an injection molding, it is difficult to form irregularities in the case itself. In the present invention, to solve the above problems by improving the structure of the speaker grill 200 to cover the speaker hole 102c without using a case shape.

The speaker grill 200 illustrated in FIG. 3 is inserted into the speaker hole 102c as shown in FIG. 4. The speaker grill 200 includes a speaker protrusion 210, a mesh 220, and a wing 230. Unlike the conventional method of attaching the film-shaped flat mesh 220 to the rear surface of the speaker hole 102c, the speaker grill 200 of the present invention is inserted into the speaker hole 102c so that the speaker protrusion 210 is placed on the case surface. It protrudes.

The speaker protrusion 210 is a part inserted into the speaker hole 102c when the speaker grill 200 is coupled to the speaker hole 102c, and protrudes from the surface of the case after the coupling. That is, even if the rear face is placed on the floor, the rear surface of the mobile terminal is spaced apart from the bottom of the mobile terminal to prevent the speaker hole 102c from being blocked, thereby securing a passage of sound.

The speaker protrusion 210 may be formed in a part of the speaker hole 102c and provided at least two so as to be stably mounted. As shown in FIGS. 3 and 4, a pair of two ends may be positioned at both ends of the mesh 220 to be inserted at both ends of the speaker hole 102c.

A portion of the speaker hole 102c other than the portion covered by the speaker protrusion 210 forms a porous mesh 220 in the speaker grill 200 so that sound can escape. The mesh 220 may be disposed at the same position as the inner surface of the case or may protrude from the surface of the case, but is located lower than the speaker protrusion 210. The sound passing through the mesh 220 may escape through the spaced space between the mounting surface formed by the speaker protrusion 210 and the case surface.

In addition to the mesh 220 and the speaker protrusion 210, a portion that is not inserted into the speaker hole 102c, that is, a wing 230 formed around the mesh 220 and the speaker protrusion 210 may be further included. The wing 230 is in contact with the inner surface of the case, serves to fix the speaker grill 200 to the case.

As shown in FIG. 4, the speaker grill 200 of the present invention has a speaker grill 200 having a speaker protrusion 210 spaced apart from the case of the mounting surface and the part of the speaker hole 102c even when the case is made of glass. The surface of the case is in close contact with the mounting surface to prevent the sound coming through the speaker hole 102c is blocked.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
