The present invention relates to an acoustic adjustment module and a mobile communication terminal having the same, and more particularly, to a new type structure that can be inclined outwardly or inwardly by a user's adjustment in a space in which an acoustic member is independently partitioned. When using a variety of content by using the characteristic that the sound source is spread differently according to the direction in which the sound member is inclined, it is to make the sense of realism, realism, three-dimensional feeling, etc. according to the user's taste.

In general, the currently released mobile communication terminal 10 has at least one acoustic member 12 separately embedded in a predetermined position as shown in the accompanying drawings of FIG. 1, and is output from the acoustic member 12. The sound is composed of a structure that can be heard by the user through the speaker hole (14).

By the way, in the conventional configuration as described above, the acoustic member 12 is a structure that is firmly fixed so as not to move left and right in the built-in position, from the stereo and sound functions basically provided in the acoustic member 12 I couldn't feel the above feeling, and thus, when the user used various contents, I could not feel more thrilling, realistic, and three-dimensional.

Furthermore, if the improvement to enhance the stereo and sound function of the sound mentioned in the above problem, the unit cost of the mobile communication terminal 10 is measured high because the performance of the acoustic member should be advanced, and accordingly the purchase cost to the consumer There was a problem that burdened me.

Accordingly, the present invention has been invented to solve the above problems, so that the fixed sound member is inclined in the outward or inward direction by the user's adjustment in the partitioned space, the stereo and sound function only by the spread of the sound source. The purpose is to help strengthen this.

The present invention for achieving the above object, the housing; A speaker hole formed on an upper surface of the housing; A plurality of amplifying means having vertically formed fixing walls for partitioning an independent space part corresponding to the speaker hole and fixing one side of an acoustic member accommodated therein; A rotating cam disposed between the amplifying means and the amplifying means to rotate about a hinge and penetrating through a fixed wall of one side and connected to a link with the other side of the corresponding acoustic member; Acoustic adjustment module comprising a link means connected to each other so that the rotary cam is rotated between the rotary cam and the rotary knob partially exposed to the upper surface of the housing so that the acoustic member is inclined in the outward and inward direction and the movement having the same There are technical features in the communication terminal.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a view showing the interior of the acoustic control module of the present invention, Figures 3a and 3b is a planar cross-sectional view showing an enlarged main portion connected between the acoustic member and the fixing wall in Figure 2, Figure 3a is "a" Part, and FIG. 3B is a part "b".

Looking at the accompanying drawings, the sound adjustment module 20 of the present invention has the following components. First, a plurality of amplification means 26 in which the housing 22 which forms a volume therein as a whole, the separate space 24 is formed separately inside the housing 22, and the space portion of the amplification means 26. The acoustic member 12 is accommodated in the (24) and arranged to be inclined in the outward or inward direction, and disposed between the amplifying means 26 and the amplifying means 26 so that the acoustic member 12 is in the outer or inner direction It consists of a link means 28 which can be tilted to. Hereinafter, the coupling relationship of the components listed above will be described in more detail.

The amplifying means 26 disposed on both sides of the housing 22, respectively, has a corresponding upper inner surface at the bottom surface of the housing 22 so that separate spaces 24 can be formed in each compartment. The fixed wall 30 is connected across and fixed.

In addition, a speaker hole 32 is drilled in the upper surface of the housing 22 corresponding to the space part 24 so that a sound source output from the acoustic member 12 may flow out. When the coiled cable 34 is connected and the acoustic member 12 is inclined outwardly or inwardly, the cable 34 is prevented from being bent due to excessive bending and stress.

In addition, the acoustic member 12 is connected to each other and the fixed wall 30 so as to properly guide the inclination when inclined in the outward or inward direction, this connection structure is specifically through the accompanying Figures 3a and 3b Explain.

First, the fixing wall 30 is formed on both inner surfaces of the guide grooves 36 and the fixing grooves 37 having a predetermined length in the vertical direction, respectively, and the guide grooves 36 are formed of the acoustic member 12. Guide protrusions 38 and fixing protrusions 39 respectively provided on both sides are inserted and coupled to each other without being separated. In particular, the fixing protrusion 39 is formed in a circular shape to allow free rotation while being fixed in a state buried in the fixing groove 37.

On the other hand, in the space formed between the amplifying means 26 and the amplifying means 26 can be interlocked between the rotary knob 40 and the rotary cam 42 disposed below the portion to be exposed to the outside. The link means 28 are arranged so as to be.

Looking at the components prior to the description of the link means 28, first, between the rotary knob 40 and the rotary cam 42 to be rotated about the hinge axis (44, 46), respectively, "C" Link members 48 having a shape of a shape are arranged and interlocked with each other.

In more detail, one end of the upper connecting piece 50 of the link member 48 passes through the lower side of the rotary knob 40 and is not separated by the fixing pin 52, and the link member 48. ), The vertical section is formed by the corrugation part 49, and when the rotation cam 42 is inverted, the vertical length of the ring member 48 is increased or shortened, so that the rotation is prevented.

  As described above, the structure for preventing the upper connection piece 50 from penetrating the rotary knob 40 and being separated by the fixing pin 52 is not limited to this example.

For example, a circular protrusion (for example, a ball) is provided at one end of the upper connection piece 50, and the circular protrusion is buried and coupled in a state in which free rotation is possible without being separated from the rotary knob 40. The structure may be possible, and further, if the link member 48 can rotate in association with the rotation of the rotary knob 40, other structural changes may be made.

 In addition, the lower connection piece 54 of the link member 48 is coupled to be eccentric to one side of the rotary cam 42 that rotates around the hinge shaft 46 fixed to the fixed wall 30, in this case, the lower At one end of the connecting piece 54, the circular protrusion 55 is embedded in the rotary cam 42 in a state capable of free rotation.

And, the side of the rotary cam 42 and the acoustic member 12, the link 56 is connected, respectively, at this time by the circular projections 58 provided on each end of the link 56, respectively. This becomes possible.

For reference, it is not necessary to limit the material of the link 56, but it may be preferably made of a slightly flexible synthetic resin material rather than a metal material so that smooth operation and joints do not occur.

In addition, the link 56 is to pass through the through hole 60 of the corresponding fixed wall 30 as shown in the above-described drawings so as to be interlocked with the acoustic member 12, wherein the through hole 60 is It may be desirable to be formed to such an extent that it does not interfere with the operating radius of the link 56.

On the other hand, Figure 5 is a plan view showing a state in which the sound adjustment module provided in the mobile communication terminal according to the present invention. Referring to the drawings, the sound control module 20 described above may be embedded in the interior of the front case 11 of the mobile communication terminal 10 as it is, or the housing 22 may be integrated with the front case 11. Acoustic adjustment module 20 may be applied to the formed state.

For example, when the housing 22 is integrally formed with the front case 11, the upper and lower end surfaces of the fixing wall 30 are fixed to the upper inner surface and the bottom surface of the front case 11, respectively.

In addition, a speaker hole 64 is formed on an upper surface of the front case 11 corresponding to the acoustic member 12, and the rotary knob 40 is also installed to partially expose the upper surface of the front case 11. It is composed of possible structures. Other configurations are the same as described above, so use the same reference numerals and omit the duplicate description.

Looking at the state of use of the acoustic control module and a mobile communication terminal having the same according to the present invention, referring to Figures 2 and 5, when the sound member is inclined in the outward direction as shown in the drawing, the spread of the sound source is greatly formed do.

In this way, when the spread of the sound source is largely formed, the user hears the intensity and time of the left and right ears with different sounds by the ear effect that senses the difference in the intensity of the sound and the difference in the arrival time by the ear. By being surrounded by the sound source, the stereo sound can be felt more, and the stereo function is improved.

When the user wants to enhance the sound function rather than the stereo function using the stereo sound, when the rotary knob 40 is rotated in the state of FIG. 2 as shown in FIGS. 3A, 3B, and 4, the rotary knob ( The link member 48 connected to 40 rotates about the hinge shaft 44 penetrating the rotary knob 40.

The lower connecting piece 54 of the link member 48 interlocked with this pushes the lower end surface of the rotary cam 42 from the front to the rear, so that the rotary cam 42 is inverted about the hinge shaft 46.

Furthermore, even if the link member 48 continues to rotate the rotary cam 42, the upper connecting piece 50 of the link member 48 hits the upper inner surfaces of the housing 22 and the front case 11 and rotates further. This is automatically stopped.

And, as described above, while the rotating cam 42 is reversed, the position of the link 56 connected between the acoustic member 12 and the rotary cam 42 is lowered, and thus the acoustic member (by the link 56) ( By pulling one side of 12), as shown in FIG. 4, the guide groove 36 of the fixed wall 30 is lowered.

Therefore, as shown in FIG. 4, when one side of the sound member 12 is lowered and inclined inward, the spread of the sound source is small.

In this way, the spread of the sound source is made small so that the sound source is collected to the user side, so that the user does not feel the difference in the intensity of the sound in the left and right ears, and the difference in the arrival time, so that each is heard as an unified sound source. The sound is enhanced rather than functioned.

For reference, in the above, the case in which the acoustic member is inclined in the outward direction and the inward direction has been described. However, the acoustic member may be positioned in a horizontal state while the acoustic member is inclined. You will hear it as a basic sound without sound enhancement.

Therefore, when using the sound adjustment module of the present invention and a mobile communication terminal having the same, when the user uses a variety of content, such as music, movies, games, etc., the three-dimensional only by tilting the acoustic member 12 by a simple operation And improve stereo with sound

As the side function enhancement is variably adjusted according to the taste of the user's work, the user's taste can be satisfied accordingly, and the sense of realism and realism can be further felt.

As described above, the present invention provides a new type of configuration in which the acoustic member is inclined outwardly or inwardly along a space partitioned independently, and physically changes the spreading of the sound source according to the direction in which the acoustic member is inclined by using the configuration. When the user uses a variety of contents such as music, games, and movies, the user can expect the effect to be more sensational, realistic or sweet by adjusting to taste.
