It may be formed integrally with the separation groove of (102). Therefore, the plurality of speaker holes 155b, 155b ′, and 155b ″ may be used as separation grooves of the exterior cover 102.

3A to 3B are diagrams for describing the structure of a mobile terminal according to a second embodiment of the present invention.

Referring to FIG. 3A, a mobile terminal 100 according to a second embodiment of the present invention includes a speaker unit 152a, a resonance unit 152b, a guide line 152c, a speaker hole 155d, and a housing unit 152d. It is configured to include.

According to the second embodiment, the mobile terminal 100 is a structure in which a conventional speaker module 152 and an earphone jack are integrated into one module, and the earphone jack is integrated with the speaker hole 155d to be a speaker hole. It is a structure to use.

The speaker unit 152a is disposed in an area adjacent to the earphone jack and is disposed in an upper area of the main body of the mobile terminal 100 to transmit sound. The speaker unit 152a is provided with a basic circuit for generating sound, and a sound hole is formed.

The resonance unit 152b is formed adjacent to one surface of the speaker unit 152a and is formed in the housing unit 152d as a space for resonating the sound transmitted from the speaker unit 152a.

The guide line 152c is formed adjacent to the surface opposite to the resonance unit 152b based on the speaker unit 152a and guides the sound generated through the speaker unit 152a in a specific direction.

The guide line 152c may be formed to be spaced apart from the resonator 152b so that the sound transmitted through the guide line 152c does not meet the sound of the resonator 152b.

The speaker hole 155d is disposed adjacent to the guide line 152c, integrally formed with the earphone jack, and transmits a sound (arrow direction) transmitted through the guide line 152c to the outside.

When the earphone jack is used as the speaker hole 155d, a sound hole is formed on a surface which is in contact with the guide line 152c and in contact with the guide line 152c is open or in contact with the outside to transmit the sound transmitted through the guide line 152c. It can be formed to be delivered to.

The housing unit 152d may house the speaker unit 152a, the resonance unit 152b, the guide line 152c, and the speaker hole 155d as a module.

Referring to FIG. 3B, the earphone jack is used as the speaker hole 155d, and the earphone jack and the speaker module are disposed adjacent to each other to form one module, thereby using the earphone jack as the speaker hole 155d and using a separate speaker hole. Since it does not need to be formed, a beautiful effect can be obtained in terms of design.

In this case, since the speaker module is formed integrally with the earphone jack, the speaker module integrated with the earphone jack is disposed above the mobile terminal 100.

4A to 4C are diagrams for describing the structure of a mobile terminal according to a third embodiment of the present invention.

4A and 4B, the mobile terminal 100 according to the third embodiment of the present invention includes a first speaker module 152, a second speaker module 152 ′, a first guide line A, The first speaker hole 155b and the second speaker hole 155c may be configured to be included.

The first speaker module 152 is disposed in the first region of the main body portion, and a through hole is formed on one surface thereof, and the lower speaker may be transmitted through the through hole. The second speaker module 152 ′ is disposed in the second region of the main body portion. And the sound is formed on one side of the hole through the hole can transmit the sound of the high range.

The first region and the second region may be adjacent regions or spatially separated regions.

The first guide line A may guide the sound transmitted through the through hole of the first speaker module 152 that transmits the low range sound in a specific direction.

The first speaker hole 155b is formed to have a step with the first speaker module 152 and is connected to the first guide line A. FIG. The first speaker hole 155b may be formed at the side of the main body to transmit the low frequency sound transmitted through the first guide line A to the outside.

Since the low range sound has a relatively attenuation characteristic as compared with the high range sound, the volume of the low range sound is not greatly reduced even when the low range sound is transmitted to the speaker hole 155b through the guide line.

The second speaker hole 155c is formed in the outer cover 102 of the main body portion corresponding to the upper part of the through hole of the second speaker module 152 ', and is transmitted through the through hole of the second speaker module 152'. You can transmit the sound of the outside.

The sound of the high range is attenuated when transmitted through the guideline, and the characteristic is significantly reduced, so that the exterior cover 102 region (the rear of the exterior cover 102) corresponding to the upper part of the through hole of the second speaker module 152 '. It is preferable to form the second speaker hole 155c).

When the lower surface of the mobile terminal 100 is in contact with an object, the high frequency sound is not easily transmitted to the outside, and thus, a second guide line connecting the second speaker module 152 'and the first speaker hole 155b. (A ') can be further formed.

When the lower surface of the mobile terminal 100 comes into contact with an object, the sound transmitted through the first speaker hole 155b formed on the side surface is louder than the sound transmitted to the second speaker hole 155c formed on the rear surface. Optimum volume can be guaranteed according to the use state of the 100.

The mobile terminal 100 may further include a controller (not shown). If a sound corresponding to the set first frequency band is generated, the controller determines that the sound is in the low range and drives the first speaker module 152. The two speaker modules 152 'may be driven.

Since the first speaker hole 155b, the first speaker module 152, and the speaker module 152 ′ are formed to have a step, the first guide line A and the second guide line A ′ are formed of the first speaker module. The through hole of 152 and the through hole of the second speaker module 152 ′ and the first speaker hole 155b may be formed in the form of a diagonal pipe.

Since the first speaker hole 155b is formed integrally with the separation groove of the exterior cover 102 of the main body, it is not necessary to form a separate hole in the exterior cover 102.

A plurality of first speaker holes 155b may be formed along the side surface of the main body, and the first guide line A and the second guide line A 'may be diagonal line pipes respectively connecting the plurality of first speaker holes. A plurality of forms may be formed (not shown).

Referring to FIG. 4C, a rear shape of the mobile terminal 100 according to the third embodiment is illustrated, and a second speaker is located in an area of the outer cover 102 corresponding to an area in which a second speaker module for transmitting high frequencies is formed. The hole 155c is formed, and the exterior cover 102 separation groove may be used as the first speaker hole 155c.

The control method for selecting a speaker module to be driven by the controller of the mobile terminal according to the present invention described above may be provided by recording on a computer-readable recording medium as a program for executing in a computer.

The control method of the mobile terminal according to the present invention can be executed through software.
