However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments disclosed herein are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. Like reference numerals designate like elements throughout the specification.

The display device according to the present invention includes a panel unit 200 for displaying an image, a housing 100 for enclosing the panel unit 200, at least two inner surfaces of the inner surface of the housing 100, And a display device including one or more speaker units 300. [0035]

1 is a perspective view of a display device 1000 according to the present invention. The display apparatus 1000 according to the present invention includes a main body 150 for displaying an image and a stand 700 for providing a standing function.

The main body 150 may include a panel unit 200 for displaying an image signal supplied from the outside as an image and a housing 100 for enclosing the panel unit 200.

The housing 100 may be divided into a plurality of covers. 1, the housing 100 includes a front cover 110 that surrounds a front edge of the panel unit 200, and a front cover 110 that is fastened to the front cover 110 to form a back surface of the display unit And may include a back cover 120.

The stand 700 includes a neck 710 for supporting a load of the main body 150 to display an image and a base 730 for dispersing the load of the neck 710 to the bottom.

In addition, the display device according to the present invention may include at least one speaker unit 300 fastened to the inner wall surface of at least two of the inner side surfaces of the housing 100.

2 to 6, a display device including at least one speaker unit 300 fastened to an inner wall surface in at least two of the inner side surfaces of the housing 100 will be described in detail .

2 is an exploded view of a display device according to the present invention. 2 (a) shows a state in which the rear cover 120 of the display device according to the present invention is disassembled. FIG. 2 (b) FIG.

2 (a) shows a state in which the rear cover 120 of the display device according to the present invention is disassembled. As shown in FIG. 2 (a), a display unit according to the present invention includes a panel unit 200 on which an image is displayed, and is coupled to a rear surface of the front cover 110.

The panel unit 200 may be provided as a module including a panel such as an LCD or a PCP. A circuit unit (not shown) for converting an image signal or an acoustic signal provided from the outside into an image and sound is formed on the back surface of the panel unit 200 in the form of at least one PCB substrate, Can be mounted.

2 (a), the space inside the housing 100, i.e., the front cover 110 and the rear cover 120 occupies most of the panel unit 200 and the circuit unit, There is not a lot of room for mounting the battery.

In addition, since the width of the bezel of the front cover 110 is minimized, when the speaker unit 300 is not mounted on the bezel of the front cover 110, the installation position of the speaker may be very limited.

In addition, although the speaker unit 300 may be mounted on the rear cover 120, since the direction in which the image is displayed and the direction in which the sound is emitted are inconsistent, the sound generated from the display device can not be effectively provided.

As a result, the inner side surfaces 110a, 110b and 110c of the front cover 110 can be selected as the mounting place S of the speaker unit 300 inside the housing 100 of the display device, . Therefore, a case where speakers are mounted on the lower side 110c of the inner side surfaces 110a, 110b and 110c of the front cover 110 as the speaker mounting place S will be described. In order to provide stereo sound, at least two or more speaker mounting places S may be provided.

Fig. 2 (b) is an enlarged perspective view of a mounting place S of the speaker of the display device according to the present invention. As shown in FIG. 2 (b), as shown in the lower side 110c of the inner side surfaces 110a, 110b and 110c of the front cover 110, An acoustic hole 112 is formed, and the generated sound can be discharged.

When the lower side 110c of the inner side surfaces 110a, 110b and 110c of the front cover 110 is selected as the installation place S of the speaker, the acoustic hole 112 or the opening . If the acoustic holes 112 or openings are formed, the rigidity of the speaker mounting place S can be relatively weakened.

That is, since the front cover 110 and the like can be made of plastic or the like, when the acoustic hole 112 or the opening is formed, if the speaker unit 300 is attached to the acoustic hole 112 or the opening, Vibration noise due to vibrations transmitted during the process of generating the vibration noise may be generated. It is preferable that such vibration noise is suppressed from occurring because it is a noise rather than an intended sound effect. The concrete method will be described later.

3 shows a speaker unit 300 mounted on a display device according to the present invention. 3 (a) is a plan view of a speaker unit 300 mounted on a display device according to the present invention, and FIG. 3 (b) is a sectional view of a speaker unit 300 mounted on a display device according to the present invention And FIG. 3 (c) is a perspective view of the speaker unit 300 mounted on the display device according to the present invention.

Generally speaking, speaker unit 300 refers to a sound device that generates sound waves by converting an electrical signal into a vibration of a diaphragm to generate a small-sized wave in the air.

That is, the speaker unit 300 is a conversion device for converting electrical energy into acoustic energy, and is largely composed of a vibration system, a support system, and mechanical parts. The speaker unit 300 can be classified into various types according to the position where the diaphragm, which is a component of the vibration system, is placed, the shape of the diaphragm, and the principle and method of converting electric signals into sound waves.

Particularly, the speaker unit 300 used in the display device according to the present invention is a radiation type speaker in which a diaphragm is directly placed in the air. When a voice signal current is supplied to a coil positioned in a magnetic field formed by a permanent magnet, It is common to use the principle that a force acts on a coil to cause movement.

On the other hand, in recent years, a large-sized display device is widely used due to the development of semiconductor technology. Loudspeakers are becoming smaller and slimmer in order to realize a beautiful and simple design of a large-sized display device, especially a flat panel display device.

When the speaker is miniaturized, the vibration system, the mechanical device, and the supporting system components constituting the speaker unit 300 must be downsized. As described above, the width of the speaker mounting place S is large and the limitation of the length is relatively small, as shown in Fig. 2, It is.

Therefore, a speaker in which the width and the thickness of the speaker are reduced and the speaker is stretched in the longitudinal direction so as not to reduce the effective vibration area of the speaker is mainly used. That is, a speaker having a rectangular shape or a large round shape with a large diameter / small diameter ratio (hereinafter referred to as "track type speaker") may be used without reducing the effective vibration area and the like of the diaphragm.

Referring to FIG. 3, the track-type speaker unit 300 will be described as follows.

The speaker unit 300 mainly includes energy conversion units 340 and 350 for converting electric energy into kinetic energy and a vibration plate 340 for converting kinetic energy generated in the energy conversion units 340 and 350 into acoustic energy. (320).

The energy conversion units 340 and 350 are composed of a fixed unit 350 and a moving unit 340 that moves relative to the fixed unit 350 by an electromagnetic force corresponding to the sound to be reproduced, A vibrating plate 320 is connected to the moving part 340 to reproduce sound by the vibration of the vibrating plate 320.

The details will be described below. The fixing portion 350 is supported at a predetermined position of the base frame 370. The fixing unit 350 includes a permanent magnet 356. An upper plate 352 and a lower plate 354 are provided on the upper and lower portions of the permanent magnet 356 to fix the permanent magnet 356, So as to concentrate the magnetic fluxes generated in the magnetic recording medium. The motion portion 340 is generally referred to as a voice coil assembly and includes a bobbin 342 and a voice coil 344 wound around the bobbin 342. The diaphragm 20 is connected to the bobbin 342. A center cap (29) is installed at the center of the diaphragm (20). The illustration number 334, which has not been described, means a gasket.

On the other hand, the lower side of the bobbin 342 is elastically connected to the base frame 370 by a damper 360. The outer side of the diaphragm 320 is connected to the base frame 370 by an elastic supporting portion 330 (hereinafter referred to as an "edge") on the upper side of the bobbin 342, . The damper 360 and the edge 330 are supporting parts and support the voice coil 344, the bobbin 342 and the diaphragm 320 in the correct positions to make smooth upward and downward movement, that is, piston movement, It is deeply involved in high output and high sound quality reproduction.

On the other hand, as described above, in the track-type speaker unit 300, the diaphragm 320 has a large ratio of long diameter to short diameter. However, the bobbin 342 has a circular shape, and the damper 60 also has a circular shape corresponding thereto. 3, the damper 360, which elastically supports the bobbin 342, is circular and is configured to wrinkle in the radial direction at the center portion 361. [ That is, the damper 360 has a plurality of corrugations 361a for drawing a concentric circle.

The operation principle of the track-type speaker unit 300 will be described with reference to FIG. 3 (b).

When a current is applied to the voice coil 344, an induction force is generated in the coil in the magnetic field formed by the permanent magnet 356, so that the voice coil 344 moves up and down, and the bobbin 342 connected to the voice coil 344 ) Also work together. Accordingly, the diaphragm 20 connected to the bobbin 342 also vibrates upward or downward, that is, the piston moves. That is, the diaphragm 20 vibrates in the back and forth direction in cooperation with the voice coil 344 and the bobbin 342, thereby vibrating the adjacent air to generate sound. As a result, the sound applied to the voice coil 344 in the form of an electrical signal is substantially reproduced by the vibration of the diaphragm 320 and radiated to the outside of the speaker unit 300.

An external sound signal and a power signal may be input through a terminal unit 390 provided in the speaker unit 300. [

3 (c) is a perspective view of the speaker unit 300 mounted on the display device according to the present invention. As shown in FIG. 3 (c), the speaker unit 300 may be provided in the form of a unit including the above-described components. The speaker unit 300 is fastened to the housing 100 of the display device through the base frame base frame fastening hole 372 formed in the base frame 370. [

A suction member 500 may be further provided to absorb and absorb vibration generated in the speaker unit 300 fastened to the housing 100 through the base frame fastening hole 372. [ The suction member 500 may be a packing member made of a rubber material.

4 is a perspective view illustrating a disassembled state of the mounting member 400 on which the speaker unit 300 of the display device according to the present invention is mounted and a assembled state thereof.

The mounting member 400 can minimize the vibration that may be generated in the speaker unit 300 and the noise generated thereby and can improve the reliability of the speaker unit 300 in the housing 100 of the display device according to the present invention. To be mounted.

In many cases, the speaker unit 300 mounted on the display device has been mounted in only one direction on the inner surface of the housing 100 of the display device.

However, in order to solve the above-described problem that may occur when the speaker unit 300 is fastened with only one direction, the speaker unit 300 is fastened to the inner wall surface of at least two of the inner side surfaces of the housing 100 A mounting member 400 as shown in Fig. 4 may be employed.

The mounting member 400 shown in FIG. 4 is a medium for mounting the speaker unit 300 to both sides of the inner surface of the front cover 110 of the housing 100.

The mounting member 400 shown in FIG. 4 includes a speaker unit 300 and a speaker unit 300 mounted to the housing 100 together with the speaker unit 300, And a housing fastening part 410 fastened to the inner wall surface of the housing 100 in a direction different from the unit mounting part 430.

The unit mounting portion 430 and the housing fastening portion 410 may be integrally formed or may be composed of separate members and coupled.

The unit mounting portion 430 of the mounting member 400 shown in FIG. 4 and the housing fastening portion 410 are provided as separate members.

The unit mounting portion 430 is fastened to the housing 100, that is, the front cover 110 in a state where the speaker unit 300 is mounted. Specifically, the unit mounting portion 430 is fastened to the bottom surface 436 of the inner surface of the front cover 110 of the housing 100, and the housing fastening portion 410 is fastened to the inner surface of the front cover 110 And the speaker unit 300 is fastened to the inner surface of the housing 100 in two directions. The speaker unit 300 is fastened to the rear surface of the front cover 110 extending from the side.

Unlike the case where the speaker unit 300 is coupled to the housing 100 only in one direction, the transmission path of the vibration generated in the speaker unit 300 can be diversified.

That is, it is possible to minimize the generation of noise due to vibrations that may occur in the vicinity of the acoustic hole 112 shown in FIG. 2 by diversifying the route in which the vibration generated in the speaker unit 300 is dispersed .

2, the sound generated from the speaker unit 300 is emitted to the outside through an opening or an acoustic hole 112 formed in the housing 100, and the speaker unit 300 has a structure, The vibration generated in the speaker unit 300 is concentrated in the direction of the housing 100 and the speaker unit 300 because the speaker unit 300 is mounted only in the inner side direction of the housing 100 in which the acoustic hole 112 is formed. It is possible to provide an additional vibration transmission path rather than mounting the speaker unit 300 only in the direction in which the sound is emitted since noise that is not intended due to such vibration may be generated, To minimize the risk of the disease.

In addition, since the mounting member 400 shown in FIG. 4 can be made of a metallic material, it also plays the role of increasing the volume and weight of the speaker unit 300 causing vibration. Therefore, if vibration of the same size is generated, the volume and weight of the vibrating object can be increased, and the vibration can be efficiently dispersed.

Again, the mounting member 400 will be described with reference to Fig. The housing fastening part 410 of the mounting member 400 includes a plurality of rear fastening holes 412 for fastening the housing 100 to the rear surface of the front cover 110 of the housing 100, .

The unit mounting portion 430 of the mounting member 400 is also provided with a fastening hole 434 so that the unit mounting portion 430 can be fastened to the lower surface of the inner surface of the front cover 110.

The unit mounting portion 430 is formed with an opening 432 through which the diaphragm of the speaker unit 300 can be exposed while the base frame of the speaker unit 300 is seated, The sound generated from the diaphragm can be emitted through the acoustic hole 112 shown in FIG.

When the speaker unit 300 is mounted on the lower surface fastening holes 434 formed at both sides of the opening 432, the above-described suction member 500 may further be inserted, And it plays a role of mitigating and dispersing the vibration to some extent.

Since the bottom surface 436 of the unit mounting portion 430 of the mounting member 400 is in contact with the lower surface of the inner surface of the front cover 110, A bonding member may be further provided on the bottom surface 436 of the unit mounting portion 430 because it may be amplified and transmitted to generate noise.

The adhesive member (not shown) may be a double-sided tape or the like having a constant thickness. The adhesive member can act as a fixing means for fixing the position of the speaker unit 300 in addition to the vibration reduction and the noise reduction effect.

The speaker unit 300 or the mounting member 400 may supplement the connection of the housing 100 such as the front cover 110 and the mounting member 400.

Fig. 5 shows a coupling relation between the speaker unit 300 and the mounting member 400 of the display device according to the present invention. 5 (a) shows a state before assembly of the speaker unit 300 and the mounting member 400 of the display device according to the present invention, and FIG. 5 (b) 5C is a sectional view of the speaker unit 300 and the mounting member 400 in an assembled state of the display device according to the present invention.

5, the mounting member 400 and the speaker unit 300 may be mounted to the housing 100 via the mounting member 400. [ The suction member 500 is positioned between the base frame fastening hole 372 of the speaker unit 300 and the lower fastening hole 434 of the unit mounting portion 430 of the mounting member 400 and is fastened by the same fastening member And can be fastened together with the speaker unit 300 and the mounting member 400.

The speaker unit 300 according to the present invention can be mounted on the unit mounting portion 430 in an inclined state. The reason why the speaker unit 300 is mounted on the unit mounting portion 430 in an inclined state is that the direction in which the sound generated from the diaphragm of the speaker unit 300 is diverted and the direction in which the image of the panel unit 200 is projected In order to reduce the difference.

That is, if the speaker unit 300 is not mounted in an inclined state, the direction in which the image is projected and the direction in which the sound is emitted are almost perpendicular. Therefore, the speaker unit 300 can be mounted in a gap so as to effectively transmit the generated sound.

5 (c), the mounting member 400 receives the speaker unit 300 at an angle so that the speaker unit 300 has a predetermined angle [theta]. In order to mount the speaker unit 300 in an inclined state, the opening 432 through which the diaphragm is exposed downward may be inclined at a predetermined angle?.

The predetermined angle [theta] may be formed so that the diaphragm can be inclined toward the front side of the front cover 110, as described above.

6 shows the coupling relationship between the speaker unit 300 and the assembly of the mounting member 400 and the cover member 600 of the display device according to the present invention. 6 (a) shows a state before the assembly of the speaker unit 300 and the mounting member 400 and the cover member 600, and FIG. 6 (b) shows a state before the speaker unit 300 and the mounting 6 (c) shows a state in which the speaker unit 300 and the mounting member 400 are assembled with the cover member 600. FIG. 6 Sectional view of a state in which the antenna 600 is mounted.

The speaker unit 300 according to the present invention is mounted on the bottom surface and the bottom surface of the inner surface of the front cover 110 of the housing 100 while being mounted on the mounting member 400. The vibrating noise generated by the vibrations transmitted from the specific portion can be alleviated to some extent by diversifying the path through which the vibration generated in the speaker unit 300 is diffused and transmitted by the mounting member 400 alone.

Since the mounting member 400 and the speaker unit 300 are coupled to each other through the absorbing member 500 interposed therebetween to mitigate and diffuse vibration generated in the speaker unit 300, And a cover member 600 for directly fastening the speaker unit 300 and the mounting member 400 to reinforce the fastening of the speaker unit 300 and the speaker unit 300.

The cover member 600 is formed with a cover hole 640 through which the fixing portion 350 of the speaker unit 300 can be protruded and a bending protrusion 620 is formed at one end thereof, And a coupling hole 610 for coupling to the attachment portion of the housing 100 is formed at the other end of the coupling hole 600. The coupling hole 414 of the cover member 600 is formed in the attachment portion of the housing 100 And can be fastened by the same fastening member as the fastening hole 414 of the fastening hole 610 corresponding to the fastening hole of the housing 100.

The cover member 600 directly connects the mounting member 400 and the speaker unit 300 fastened through the suction member 500 to transmit a vibration transmission path generated in the speaker unit 300 And the vibrations generated in the speaker unit 300 can be effectively diffused and alleviated.

6 (b), the assembly of the speaker unit 300 and the mounting member 400 on which the cover member 600 is mounted is fixed to the front cover 110 by fastening members such as bolts, And is fastened to the back surface and the lower surface of the front cover 110 in two directions of the inner surface.

6 (c), the cover member 600 includes the speaker unit 300 and the mounting member 400, as shown in a cross-sectional view in which the cover member 600 is mounted on the assembly of the speaker unit 300 and the mounting member 400, The speaker unit 300 and the mounting member 400 are connected by the bending protrusion 620 and the fastening hole 610 in a state in which the speaker unit 300 and the mounting member 400 are pressed.

The cover member 600 directly connects the mounting portion of the housing 100 and the base frame of the speaker unit 300 to directly transmit the vibration generated in the speaker unit 300 to the back surface of the front cover 110 As shown in FIG.

Therefore, even if vibration of the same size occurs, the size and weight of the vibrating body can be increased, and the size of bodily-sensible vibration can be effectively reduced.

According to the display apparatus of the present invention, it is possible to minimize vibration or noise caused by a speaker that converts a sound signal into sound in a display device that is slimmed and to securely mount the speaker unit 300, and the speaker unit 300 Is reinforced to reduce the breakage and failure of the display device and improve the durability of the display device.
