The speaker unit 300 may be classified into various types according to a position on which a diaphragm, which is a vibration system component, and a shape of a diaphragm, a principle and a method of converting an electrical signal into sound waves, and the like.

In particular, the speaker unit 300 used in the display device according to the present invention is a radiating speaker in which the diaphragm is placed directly in the air, and when a voice signal current flows to a coil located in a magnetic field formed by a permanent magnet, It is common to use the principle that the force acts on the coil to generate the movement.

On the other hand, in recent years, with the development of semiconductor technology, a large display device is widely used. Speakers have also been miniaturized and slimmed in order to realize a beautiful and concise design of a large display device, especially a flat panel display.

When the speaker is downsized, the vibration system, magnetic field, and support system components constituting the speaker unit 300 should be downsized. As described above, the mounting place S of the speaker is not large in its selection, and as shown in FIG. 2, the limitation of the width and thickness of the speaker mounting place S is large, and the limitation of the length is relatively small. On the side.

Therefore, a speaker of a type that does not reduce the effective vibration area of the speaker by increasing in the longitudinal direction while reducing the width and thickness of the speaker may be mainly used. That is, a rectangular or long oval speaker having a large diameter / short diameter ratio (hereinafter referred to as a “track type speaker”) may be used without reducing the effective vibration area of the diaphragm.

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

The speaker unit 300 includes energy conversion units 340 and 350 for converting electrical energy (electric signals) into kinetic energy and vibration plates for converting kinetic energy generated from the energy conversion units 340 and 350 into acoustic energy. And 320.

The energy converters 340 and 350 are composed of a fixed part 350 which is fixed, and a moving part 340 which moves relative to the fixed part 350 by an electromagnetic force corresponding to a sound to be reproduced. The diaphragm 320 is connected to the exercise unit 340 to reproduce sound by the vibration of the diaphragm 320.

It will be described in detail as follows. The fixing part 350 is supported at a predetermined position of the base frame 370. The fixing part 350 is configured to include a permanent magnet 356, the upper and lower portions of the permanent magnet 356 is provided with an upper plate 352 and a lower plate 354, respectively, the permanent magnet 356 It is common to concentrate the magnetic flux that occurs at. The moving part 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. In addition, the diaphragm 20 is connected to the bobbin 342. A central cap 29 is installed at the center of the diaphragm 20. Unexplained reference numeral 334 denotes a gasket.

On the other hand, the lower side of the bobbin 342 is elastically connected to the base frame 370 by the damper 360. In addition, the upper side of the bobbin 342 is connected to the diaphragm 320, the outer side of the diaphragm 320 is also connected to the base frame 370 by an elastic support 330 (hereinafter referred to as "edge"). It is common to be. The damper 360 and the edge 330 is a support system component, and supports the voice coil 344, the bobbin 342, and the diaphragm 320, which are the vibration system components, in a correct position to perform a smooth vertical movement, that is, a piston movement, Deeply involved in high power and high sound quality reproduction.

On the other hand, as described above, in the track-shaped speaker unit 300, the diaphragm 320 has a shape in which the ratio between the long diameter and the short diameter is large. By the way, the bobbin 342 is circular shape, and the damper 60 is also circular shape correspondingly. As shown in FIG. 3, the damper 360 elastically supporting the bobbin 342 is circular, and is configured to be corrugated in the radial direction at the center portion 361. That is, the damper 360 has a plurality of wrinkles (361a) of approximately concentric circles.

Referring to Figure 3 (b), the operation principle of the above-described track-type speaker unit 300 will be described as follows.

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 to move the voice coil 344 up and down, and the bobbin 342 connected to the voice coil 344. ) Will also work in conjunction. Accordingly, the diaphragm 20 connected to the bobbin 342 also vibrates in a piston motion up and down. That is, the diaphragm 20 vibrates in the front-back direction in conjunction with the voice coil 344 and the bobbin 342 to vibrate adjacent air to generate sound. As a result, the sound applied in the form of an electrical signal to the voice coil 344 is substantially reproduced by the vibration of the diaphragm 320 to be radiated to the outside of the speaker unit 300.

Sound signals and power signals provided from the outside may be input through the terminal unit 390 provided in the speaker unit 300.

3 (c) is a perspective view of the speaker unit 300 mounted to 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 one unit including the aforementioned components. As will be described in detail later, the speaker unit 300 is fastened to the housing 100 of the display apparatus through a base frame base frame fastening hole 372 formed in the base frame 370.

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

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

The mounting member 400 suppresses the generation of vibration and noise caused by the speaker unit 300 to the maximum, and reliably the speaker unit 300 in the housing 100 of the display device according to the present invention. It is adopted to mount.

Conventionally, the speaker unit 300 mounted on the display device is often mounted only in one direction on the inner surface of the housing 100 of the display device.

However, in order to solve the above-described problems that may occur when the speaker unit 300 is fastened in only one direction, the speaker unit 300 is fastened to an inner wall surface of at least two directions of inner surfaces of the housing 100. In order to employ the mounting member 400 as shown in FIG.

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

The mounting member 400 illustrated in FIG. 4 is a unit mounting part in which the speaker unit 300 is mounted and fastened to the housing 100 together with the speaker unit 300 in a state where the speaker unit 300 is mounted. 430 and a housing fastening part 410 fastened to an inner wall surface of the housing 100 in a direction different from that of the unit mounting part 430.

The unit mounting part 430 and the housing fastening part 410 may be integrally formed or may be configured as a separate member and combined.

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

The unit mounting portion 430 is fastened to the housing 100, that is, the front cover 110, with the speaker unit 300 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, the housing fastening portion 410 is the inside of the front cover 110 The speaker unit 300 is fastened to the rear surface of the front cover 110 extending from the side is characterized in that the fastening in two directions of the inner surface of the housing 100.

Unlike the case in which the speaker unit 300 is fastened to the housing 100 only in one direction, the transmission path of the vibration generated from the speaker unit 300 may be diversified.

That is, by varying the path in which the vibration generated in the speaker unit 300 is dispersed, it is possible to minimize the generation of noise due to vibration that can be generated in the vicinity of the sound hole 112 and the like shown in FIG. .

As shown in FIG. 2, the sound generated from the speaker unit 300 has a structure that is emitted to the outside through an opening or a sound hole 112 to be formed in the housing 100, and the speaker unit 300. Since the sound hole 112 is mounted only in the direction of the inner surface of the housing 100, the vibration generated in the speaker unit 300 is concentrated in the direction of the housing 100 and the speaker unit 300 Undesired noise may be generated by the vibration, and thus, noise caused by vibration generated to provide an additional vibration transmission path than the speaker unit 300 is mounted only in a direction in which sound is emitted. It can be said to minimize the

In addition, since the mounting member 400 illustrated in FIG. 4 may be made of a metallic material, the mounting member 400 also increases the volume and weight of the speaker unit 300 causing vibration. Therefore, if vibration of the same magnitude is generated, it is possible to efficiently distribute the vibration by increasing the volume and weight of the vibrating object.

Again, the mounting member 400 will be described with reference to FIG. 4. The housing fastening portion 410 of the mounting member 400 is provided with a plurality of rear fastening holes 412 for fastening with the housing 100 and the rear surface of the inner surface of the front cover 110 of the housing 100. And can be fastened.

In addition, the unit mounting portion 430 of the mounting member 400 is also provided with a lower surface fastening hole 434 to be fastened to the lower surface of the inner surface of the front cover 110.

The unit mounting part 430 has an opening 432 formed so that the diaphragm of the speaker unit 300 can be exposed while the base frame of the speaker unit 300 is seated, and the opening 432 is formed. Sound generated in the diaphragm may be emitted through the sound hole 112 shown in FIG. 2.

When the speaker unit 300 is mounted in the lower surface fastening hole 434 formed at both sides of the opening 432, the above-mentioned suction member 500 may be further interposed, and the speaker unit 300 may be generated. It plays a role of mitigating and distributing the vibration to some extent.

In addition, since the bottom surface 436 of the unit mounting portion 430 of the mounting member 400 is a part which is in contact with the lower surface of the inner surface of the front cover 110, the vibration is generated according to the contact state when the vibration occurs An adhesive member may be further provided on the bottom surface 436 of the unit mounting part 430 because it may be amplified and transmitted to generate noise.

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

It may serve to supplement the fastening of the housing 100, such as the front cover 110 and the speaker unit 300 or the mounting member 400.

It may be fastened together with the speaker unit 300 and the mounting member 400.

In addition, the speaker unit 300 according to the present invention may be mounted to the unit mounting part 430 in an inclined state. The reason why the speaker unit 300 is mounted to the unit mounting unit 430 in an inclined state is that the sound generated from the diaphragm of the speaker unit 300 is emitted and the projection direction of the image of the panel unit 200. This is 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 become almost vertical. Therefore, in order to effectively transmit the generated sound, the speaker unit 300 may be mounted diagonally.

As shown in FIG. 5C, the mounting member 400 accommodates the speaker unit 300 inclined such that the speaker unit 300 has a predetermined angle θ. In order to mount the speaker unit 300 in an inclined state, the opening 432 to which the diaphragm is exposed may be configured to be inclined at a predetermined angle θ.
