Since the frequency of the output sound of the receiver 200 and the frequency of the output sound of the sound output port 103 of the front case 101 are almost equal to each other ) Can be kept the same.

The second sound output port 211 emits sound toward the upper side of the receiver 200 and emits an additional sound volume other than the first sound output port so that the output volume of the sound of the receiver 200 can be supplementarily increased. Since the sound emitted from the second sound output port 211 causes a slight spatial interference with the front case 101 while the second sound output port 211 is a component that assists the output volume of the receiver 200, The second sound volume releasing aperture can not change the overall sound frequency of the receiver 200 while increasing the output sound volume of the receiver 200.

5 and 6, the receiver 200 surrounds the upper surface, the lower surface, and both sides of the receiver housing 210 and the front protector 220, and the receiver housing 210 and the front protector 220, And a sealing member 230 for sealing the inside of the sealing member 220.

The sealing member 230 is made of a polymer material such as plastic or rubber and the sealing member 230 is integrally formed with the upper surface, the lower surface and both side surfaces of the receiver housing 210, As shown in Fig.

The sealing member 230 has an opening 231 at a position corresponding to the first sound output port 221 of the front protector 220 and the second sound output port 211 of the receiver housing 210 . That is, when the sealing member 230 is attached to the front protector 220 and the receiver housing 210, a part of the opening 231 is located above the first sound output port 221, and the opening 231 ) Is located at the upper part of the second sound output port 211. [

Since the sealing member 230 having the opening 231 at the position corresponding to the first sound output port 221 and the second sound output port 211 is provided as described above, the front protector 220 and the receiver housing 210 The sound output from the receiver 200 can be released only to the first sound output port 221 and the second sound output port 211 The output volume of the receiver 200 can be increased.

Preferably, the opening 231 of the sealing member 230 may be provided with meshes 233. The mesh unit 233 can prevent foreign substances such as dust from entering the receiver 200 and allows the sound output from the receiver 200 to be easily discharged to the outside.

As shown in FIG. 6, the receiver housing 210 and the front protector 220 include components 240 for outputting the sound of the receiver 200. The components 240 for outputting the sound of the receiver 200 may be configured in various combinations of various components.

For example, the components 240 for outputting the sound of the receiver 200 may be configured to receive acoustical current (for example, from a printed circuit board provided in the terminal body) from the terminal body via the input terminal 241a (E. G., Circular) yoke (e. G., Circular) that is received in the frame 241 and passes magnetic flux generated from the acoustic current A voice coil 243 which is accommodated in the yoke 242 and receives the acoustic current and is vibrated by the acoustic current and a voice coil 243 which is connected to the voice coil 243, A diaphragm 244 for generating sound and an anti-vibration member 245 provided behind the frame 241 are provided. At this time, a magnet may be provided in the yoke 242.

In operation of the receiver 200, an acoustic current signal including a plurality of frequencies is applied to the voice coil from the input terminal of the frame, thereby causing the voice coil to vibrate mutually with respect to the yoke, Thereby generating mechanical energy (i.e., vibration energy). The diaphragm attached to the voice coil generates vibration due to the vibration of the voice coil, thereby generating a sound pressure or sound of a predetermined size that can be perceived by the human ear. The generated sound is transmitted to the receiver via the sound output port 103 through the first sound output port 221 and the second sound output port 211 according to the present invention.

7 is a schematic front view of the front case of the mobile terminal 100 according to the present invention.

7, the mobile terminal 100 having the receiver 200 and the front case 101 according to the present invention can increase the volume of the receiver 200 and increase the volume of the sound output port of the front case 101 while increasing the volume of the receiver 200. [ The width d2 of the sound output port 103 can be significantly reduced compared to the width d1 of the sound output port 103 according to the prior art shown in Fig. For example, the width d1 of the sound output port 103 according to the related art should be at least 1.5 mm to 2.5 mm or more in order not to reduce the output volume of the receiver 200, The output sound volume of the receiver 200 can be sufficiently secured if the width d2 of the sphere 103 is 0.4 mm to 0.8 mm.

As described above, according to the present invention, the present invention can provide the mobile terminal 100 that minimizes the size of the sound output port 103 in the front case and does not reduce the output of the receiver 200 at the same time. Therefore, the present invention can improve the aesthetics of the mobile terminal 100, increase the output volume of the receiver 200, and at the same time, the receiver 200 due to the spatial interference between the receiver 200 and the front case, It is possible to prevent the frequency variation of the output sound of the speaker.

It is to be understood that the configurations and methods of the above-described embodiments (mobile terminal 100) having the above-described (name) can be applied to a limited number of embodiments, All or a part of the above-described elements may be selectively combined.
