The rear camera 121 ′ has a photographing direction substantially opposite to the front camera 121, 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 '.

A speaker 152 ′ may be additionally disposed at the rear of the terminal body. The sound output unit 152 ′ at the rear of the body may implement a stereo function together with the receiver 152 at the front of the body, and may be used to implement a speakerphone mode during a call.

3 is a cross-sectional view of a portion of the receiver 152 and the first microphone 122 of the present invention, in which a front case 101, a window glass 109, a receiver 152, and a first microphone 122 are shown.

The window glass 109 of the present invention is characterized in that the opening 109a communicating with the receiver 152 and the first microphone 122 is formed. Both the receiver 152 and the first microphone 122 are located above the front of the mobile terminal. If two openings are formed for the receiver 152 and the first microphone 122, the front design becomes complicated.

Therefore, the receiver 152 and the first microphone 122 are disposed to communicate with each other through one opening 109a, and a mesh 1525 may be provided to visually cover the inside of the opening 109a, and may be waterproof. In order to improve the function, the waterproof filter 1526 may be provided. The waterproof filter 1526 has a microstructure that passes sound but does not pass water. For example, a Goretex filter can be used.

The front case 101 has a through window for the display unit 151, a receiver hole 101a for the receiver 152, and a microphone hole 101b for the first microphone 122. Unlike the window glass 109, since it is not directly exposed to the front surface, two holes may be formed in the front case 101. When formed as one, such as the opening 109a of the window glass 109, the waterproof performance may be deteriorated, so that the receiver glass 101a and the microphone hole 101b are formed separately.

That is, it is necessary to provide a receiver hole 101a and a microphone hole 101b separately to closely contact the upper surface and the case 101 so as to be waterproof. In the case of the receiver 152 having its own waterproof function, as shown in FIG. 3, between the receiver hole 101a and the receiver 152 to closely contact the case 101 and the receiver 152. Water leakage can be prevented through the waterproof tape 1521.

Since the first microphone 122 is not provided with a waterproof function by itself, the waterproof microphone 1221 is interposed between the microphone hole 101b and the first microphone 122 as shown in FIG. 3. The waterproof filter 1221 covers the microphone hole 101b from the inside, and may use a Gore-Tex filter having a microstructure that passes air but does not pass water.

The microphone hole 101b may include a stepped portion 101c to have a larger size at the rear surface than the front surface. The step 101c is to improve the waterproof performance, so that the waterproof filter 1221 is positioned on the step 101c, and the first microphone 122 presses the step 101c, whereby the front case and the microphone 122 are pressed. Make sure they are in close contact.

In particular, the front surface of the rubber 1222 is in contact with the step (101c) via the elastic rubber 1222 between the microphone 122 and the step (101c), located between the rubber 1222 and step (101c) The waterproof filter 1221 is compressed so that water does not leak through the circumference.

In addition, the rear surface of the rubber 1222 may be formed with a recessed portion such that the first microphone 122 is inserted to fix the first microphone 122. In addition, the rubber 1222 has a hole in communication with a hole formed in the microphone 122 so that a sound can be input to the microphone 122.

As described above, according to at least one of the embodiments of the present invention, the front design can be more concise by making only one opening 109a visible, and the receiver 152 and the microphone 122 on the front case. It is possible to waterproof by forming a separate hole in communication with.

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.
