Referring to FIG. 3, a camera 121 'may be further mounted on the rear surface of the terminal body, that is, the rear case 102. The camera 121 'may have a photographing direction substantially opposite to the camera 121 (see FIG. 2A), and may be a camera having different pixels from 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 so as to be rotatable or pop-upable.

The antenna 124 constituting a part of the broadcast receiving module 111 (see FIG. 1) may be installed to be able to be drawn out from the terminal body.

A power supply unit 190 for supplying power to the mobile terminal 100 is mounted on the terminal body. The power supply unit 190 may be built in the terminal body or may be detachable from the outside of the terminal body.

Hereinafter, the mobile terminal 100 in which the structure of the sound output module 152 is simplified will be described in more detail.

Fig. 4 is an enlarged view showing the assembly gap 200 shown in Fig. 2, and Fig. 5 is an enlarged view showing the assembly gap 300 as another example of the mobile terminal related to the present invention.

4 and 5, the window 155 is disposed to cover the display unit 151, and may be mounted on the front surface of the front case 101. The window 155 is coupled with the front case 101 to form an appearance of the rear case 102 and the mobile terminal 100.

A proximity sensor 141 may be disposed adjacent to the sound output module 152 to sense an object to be accessed. The control unit 180 controls various operations to be applied to the mobile terminal 100 according to proximity of the object.

Assembly clearances 200 and 300 are formed at the edges of the window 155 by the combination of the front case 101 and the window 155 and two independent members. Sound emission line portions 210 and 310 through which sound can be output may be formed in the assembly gaps 200 and 300 formed between the upper end of the window 155 and the front case 101.

Since the assembly openings 200 and 300, which are inevitably generated in the process of assembling various components of the mobile terminal 100, are used as passages through which sound can be transmitted, holes independently formed for sound output are unnecessary . Therefore, the structure of the mobile terminal 100 can be further simplified, and the production process can be simplified.

In addition, since a hole for sound output is not apparently seen, a mobile terminal 100 having a simpler appearance and improved in design can be provided.

The sound emission line portions 210 and 310 may be formed in one section of the assembly gaps 200 and 300, for example, at the center of the assembly gaps 200 and 300. In this case, both side regions of the sound emission line portions 210 and 310 may form sound shielding line portions 220 and 320 so that sound is concentrated to the sound emission line portions 210 and 310.

The sound shielding line portions 220 and 320 may be configured to shield the region except the sound emission line portions 210 and 310 as the supporting surface of the window 155 when the window 155 is mounted to the front case 101 have.

The sound emission line portions 210 and 310 may be formed so as to be continuous with the assembly gaps 200 and 300. For example, referring to FIG. 4, the sound emission line portions 210 and 310 are disposed on the same assembly gap 200 and 300 as the sound shield line portions 220 and 320 formed in both side regions. The area forming the sound emission line parts 210 and 310 may be such that the upper end of the window 155 is undercut toward the lower end.

Alternatively, as shown in FIG. 5, the sound emission line portions 210 and 310 may have the same height as the sound shield line portions 220 and 320.

6 is a cross-sectional view showing that sound and light generated from the sound source 230 and the light source 250 shown in FIG. 2 are emitted to the outside through the assembly gap 200. FIG.

Referring to FIG. 6, a sound source 230 is mounted inside the mobile terminal 100. The sound source 230 may serve as a receiver in the communication mode and as a speaker in the audio output mode.

However, when the sound source 230 is used as a receiver, since the user is close to the mobile terminal 100, the maximum volume should be lower than when the sound source 230 is used as a speaker. The control unit 180 may recognize the case where the object is close to the window 155 through the proximity sensor 141 as a communication mode and control the volume by adjusting the maximum volume to the standard of the receiver.

Sound transmission brackets 240/241, 242, and 243 may be disposed on the front surface of the sound source 230. The sound path bracket 240 guides the transmission of sound generated from the sound source 230. Sound is transmitted through the sound path bracket 240 and is output to the outside through the sound emission line portion 210 of the assembly gap 200.

A printed circuit board 182 may be disposed in a region adjacent to the sound source 230 and a light source 250 may be provided on the printed circuit board 182. The light source 250 may be disposed on a path through which sound is transmitted so that light generated from the light source 250 may be output to the outside through the sound emission line unit 210 together with the sound.

Since the light transmitted from the light source 250 is transmitted along with the sound on the path through which the sound is transmitted, the mobile terminal 100 may be configured to implement various interfaces according to the state.

The sound path bracket 240 is completely shielded so that the light output through the light source 250 does not leak into a region other than the sound emission line portion 210. In particular, the sound path bracket 240 disposed in the vicinity of the assembly gap 200 and structures adjacent to the sound path bracket 240 may be formed of an opaque material to prevent light from passing therethrough.

7 is a cross-sectional view of a mobile terminal 100 according to another embodiment of the present invention in which sound and light generated from a sound source 230 and a light source 250 are emitted to the outside through an assembly gap 200 .

Referring to FIG. 7, the light source 250 may be disposed adjacent to the sound source 230, and may be disposed outside the sound path bracket 240 so as to deviate from the path through which the sound is transmitted. The sound path bracket 240 adjacent to the light source 250 is formed of a translucent material so that light emitted from the light source 250 passes through the sound path bracket 240 and is emitted from the sound source 230, (210). ≪ / RTI >

In such a structure, since the light source 250 does not interfere with the transmission of sound by deviating from the transmission path of the sound, a more accurate sound can be output.

8 is a flowchart illustrating a method of outputting light generated from a light source 250, as an example of the mobile terminal 100 according to the present invention.

When the call mode is selected, the call is started. On the other hand, if the communication mode is not selected, the power supply to the light source 250 is interrupted.

The proximity sensor 141 disposed adjacent to the window 155 senses an object approaching the window 155. When the object approaches the window 155, the control unit 180 can cut off the power supply to the light source 250 and control the volume to match the maximum value of the receiver.

If the object does not approach the window 155, the control unit 180 may supply power to the light source 250 so that the user can confirm the position of the sound emission line unit 210.

When the call is terminated, power to the light source 250 is cut off and the mobile terminal 100 is switched to the standby mode.

9 is a flowchart illustrating a method of outputting light generated from a light source 250 as another example of the mobile terminal 100 according to the present invention.

When the call mode is selected, the call is started. When the call is terminated, the power to the light source 250 is cut off and the mobile terminal 100 is switched to the stand-by mode. On the other hand, if the communication mode is not selected, the power supply to the light source 250 is interrupted.

When the call button is pressed to start the call, the power supply to the light source 250 is cut off, and power can be supplied to the light source 250 at predetermined time intervals. When making a call using a headset or making a video call using the camera 121, the user can confirm the talk time through the blinking light.

In addition, in the case of the mobile terminal 100, particularly the mobile terminal 100 of the touch type, the touch input may not be recognized and the call mode may not be terminated. In this case, the user can confirm whether or not the communication mode is available through the blinking light.

The mobile terminal described above is not limited to the configuration and method of the embodiments described above, but the embodiments may be configured by selectively combining all or a part of the embodiments so that various modifications may be made.
