In this case, since only the battery cover 203 covers the antenna 310, the transmission / reception performance of the antenna 310 can be improved because the influence of other structures is relatively small.

An antenna 310 is disposed on at least one side of the first frame 301. The antenna 310 has a predetermined pattern of a conductive material and is electrically connected to the printed circuit board 281 so that the wireless signals transmitted and received are processed.

5 and 6, the antenna 310 is connected to the inner surface of the first frame 301 (the surface facing the bottom of the antenna speaker module seating portion 244) through holes formed in the first frame 301, . The extended portion is formed so as to protrude in the direction toward the printed circuit board 281 by forming ground and power feed terminals 312a and 312b. The ground and power supply terminals 312a and 312b are electrically connected to the printed circuit board 281 and the connection terminal 283 may be provided on the printed circuit board 281 for the connection.

The antenna 310 is configured to transmit and receive wireless electromagnetic waves of a specific frequency band, and the frequency band corresponds to at least one of a personal communication system (PCS), an advanced wireless service (AWS), and a digital communications network Frequency band.

The antenna 310 is configured to transmit and receive multi-band radio signals. That is, the antenna 310 may be a multi-band antenna. For example, the antenna 310 includes first and second radiation patterns 311a and 311b that branch off about the ground and power feed terminals 312a and 312b.

The first and second radiation patterns 311a and 311b may be formed, for example, by printing a conductive ink on at least one side of the first frame 301 and plating the conductive ink with a metal. The first and second radiation patterns may be formed of metal thin plates such as gold, copper, or the like, and may be electrically connected to the printed circuit board 281 through the first frame 301.

An opening 325 is formed in the second frame 302 so that sound output from the speaker 320 can be emitted. The opening 325 may be disposed on the bottom surface of the portion where the speaker 320 is mounted. The opening 325 may be additionally formed at a portion spaced apart from the speaker 320 so as to emphasize the output of a specific sound (e.g., bass) by the diffraction of sound.

The opening 325 may be provided with a vibration damping net 326 for preventing dust or foreign matter from penetrating into the speaker 320.

An opening sealing pad 327 may be disposed at an edge of the opening 325 to surround the opening 325. The opening sealing pad 327 restricts leakage of sound to areas other than the acoustic output tube defined by the second frame 302 and the rear case 202. [ The opening sealing pad 327 may be made of an elastically deformable material so that the antenna speaker module 300 is compressed by being coupled to the rear case 202.

7 is an exploded view of the antenna speaker module 300 shown in FIG.

Referring to FIG. 7, the antenna speaker module 300 includes first and second frames 301 and 302 forming an outer appearance.

The sealing pads 330 may be fixed to the first or second frame 301 or 302 with a double-sided tape, or may be inserted into a recess formed along the edge. Alternatively, the sealing member may be formed in such a manner that the liquid sealing member is directly applied and cured on one side of the first or second frame 301 or 302 and adhered thereto.

Coupling means for engaging are formed on the inner surfaces of the first and second frames 301 and 302, that is, the surfaces forming the inner spaces when the first and second frames 301 and 302 are engaged. The coupling means may be hook structures 341a and 341b, fusion structures 342a and 342b, interference fit structures 343a and 343b, etc., and may be made to be more rigidly coupled through a plurality of structures.

The first and second frames 301 and 302 may have hooking hooks 341a and hooking grooves 341b, respectively. The hooking hook 341a is formed to protrude from one surface of the first frame 301 and the hooking groove 341b can be recessed from one surface of the second frame 302 so that the hooking hook 341a can be received have.

The hooking hook 341a and the hooking groove 341b are formed at one side of the first and second frames 301 and 302 to engage the first and second frames 301 and 302 together with other engaging means, 330, respectively.

The first frame 301 is formed with a first protrusion 342a protruding from one side and the second frame 302 is formed with a through hole 342b through which the first protrusion 342a can pass have. The first protrusion 342a is inserted into the through hole 342b and the exposed portion through the through hole 342b is fused to join the first and second frames 301 and 302. [

7, a hooking hook 341a and an engaging groove 341b are formed on one side of the first and second frames 301 and 302, and fusion bonding structures 342a and 342b are formed on the other side of the first and second frames 301 and 302 . The first and second frames 301 and 302 are coupled with each other through the coupling means as described above, and the sealing pad 330 is compressed so that the inner space can be sealed.

A second projection 343a formed to protrude from one surface is formed in the first frame 301 and a second projection 343a can be fitted to one surface of the second frame 302. [ Receiving grooves 343b may be formed. The width of the second protrusion 343a may be made larger than the width of the receiving groove 343b so that the second protrusion 343a can be engaged with the receiving groove 343b in an interference fit.

According to the above structure, the sealing pads 330 are disposed between the first and second frames 301 and 302, and the sealing pads 330 are coupled with the first and second frames 301 and 302 By being squeezed, the inner space of the antenna speaker module 300 can be sealed. The first and second frames 301 and 302 are firmly coupled through the coupling means such as the hook structures 341a and 341b, the fusion structures 342a and 342b, and the interference fit structures 343a and 343b, The sealing pad 330 can be kept in a squeezed state.

Since the first and second frames 301 and 302 are defective through the sealing pad 330 and the coupling means, it is possible to solve the problems of damage to the antenna 310 or adhesion failure that may occur when the first and second frames 301 and 302 are combined by ultrasonic welding or bonding . In addition, since the pattern region of the antenna 310 can be extended to a portion adjacent to the coupling surface of the first and second frames 301 and 302, the radio characteristics of the antenna 310 can be improved. In addition, leakage of sound output from the speaker 320 due to adhesion failure can be prevented.

A speaker 320 is mounted in the inner space formed by the first and second frames 301 and 302. A flexible printed circuit board 322 electrically connected to the speaker 320 may be disposed on one side of the speaker 320. The shield member 323 may be mounted on the upper surface of the flexible printed circuit board 322 such that the flexible printed circuit board 322 does not affect the antenna 310 electrically.

A speaker damper 321 is disposed between the first frame 301 and the speaker 320. The speaker damper 321 separates the speaker 320 from the first frame 301 so that the speaker 320 is not in direct contact with the first frame 301.

Fig. 8 is a sectional view showing an acoustic output tube line defined by the second frame 302 and the rear case 202 of Fig.

Referring to FIG. 8, the antenna speaker module 300 is mounted on an antenna speaker module seating portion 244 formed in the rear case 202. The antenna speaker module 300 may be arranged to cover a part of the user input portion 231 or the display module 251. [

As shown in the figure, the rear case 202 is disposed on one side of the second frame 302, and the second frame 302 and the rear case 202 are open Thereby forming a space. Accordingly, the sound output from the speaker 320 may be emitted to the outside of the terminal body through the opening 325 and through the acoustic hole 245.

The first and second frames 301 and 302 and the front and rear cases 202 and 202 are formed by the second frame 302 and the rear case 202. However, The method of forming the acoustic output tube can be diversified. That is, the acoustic output tube can be formed by at least one frame and at least one case.

Since the sound outputted from the speaker 320 is emitted to the acoustic hole 245 along the acoustic output tube path defined by the second frame 302 and the rear case 202, The acoustic output path can be formed only by the arrangement of the first and second acoustic waveguides 202. That is, it is not necessary to form a channel for the separate output of sound to the antenna speaker module 300, so that the structure of the antenna speaker module 300 can be simplified.

9, the antenna speaker module 300 includes a first area A in which the antenna 310 is disposed and a second area B in which the speaker 320 is disposed. The second area B may be formed to be spaced apart from the first area A so that the speaker 320 does not electrically affect the antenna 310. [

The antenna 310 is patterned on at least one side of the first frame 301. As shown, the antenna 310 may be disposed on an outer surface 301a, an inner surface 301b, and a side surface 301c of the first frame 301. The antenna 310 may extend from the first region A and extend toward the second region B along the side 301c intersecting the second region B. [

According to the above structure, the pattern area of the antenna 310 can be expanded by extending the antenna 310 so as not to overlap with the second area B where the speaker 320 is mounted. Accordingly, the mobile terminal 200 with improved radio performance can be implemented.
