The present invention is coupled to the diaphragm partitioning the speaker unit integrally formed on both sides of the front mask to improve the rigidity of the relatively thin diaphragm due to gas injection, the auxiliary plate extending from the side between the speaker and the speaker unit It relates to a front mask reinforcement bracket of a television, characterized in that to suppress the vibration by widening the coupling interval between the speaker unit and the speaker.

In general, display devices such as TVs and monitors are being developed in the form of a CRT, a liquid crystal display (LCD), and a plasma display panel (PDP).

Here, the CRT-type television visually expresses an image by a display device called a cathode ray tube. The cathode ray tube is an electron gun precisely focusing an electron beam in a predetermined circle, and is generally formed to have a length in the rear.

1 is a diagram illustrating a front mask of a conventional television.

The rear surface of the front mask 11 shown in the center is formed with an opening hole 12 for exposing the CRT and a rib 13 for supporting the CRT in close proximity to the opening hole 12.

And, both sides of the front mask 11 is formed with a speaker unit 15 for mounting a speaker, the speaker unit 15 is formed with a discharge hole 16 for sound transmission, speaker not shown A plurality of bosses 17 are formed for mounting of the wah.

The front mask 11 is molded of a plastic material, and in the case of a plastic injection design, a gas injection design is becoming common, and this gas injection increases the rigidity of the front mask 11.

In the gas injection, when the gases facing each other through the channel meet each other, the gas may burst out of the molding, thereby causing molding failure.

For this reason, the vertical diaphragm 18 of the front mask 11 which is a site where a gas frequently meets is designed intentionally thin.

However, the diaphragm serves as a boundary between the speaker and the CRT, but may be bent due to the weight of the CRT, causing a deformation of the overall front mask.

On the other hand, when the speaker is directly fastened to the boss of the speaker unit, there is a problem that the distance between the speaker unit and the speaker is narrow, the fastening strength of the speaker is high, the vibration caused by the sound is large.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to provide a separate bracket to reinforce the diaphragm of the front mask formed by gas injection molding.

In addition, an object of the present invention is to reduce the vibration caused by the generation of sound by a portion of the bracket is fastened to the boss of the speaker unit is not fastened directly to the speaker unit.

The present invention for achieving the above object is in the front mask of the television is integrally formed with a speaker unit for mounting the speaker on both sides,

The rear face of the front mask is provided with a diaphragm for partitioning the mounting portion of the CRT and the speaker, the bracket having an insertion groove for inserting the diaphragm is provided with a front mask reinforcement bracket of the television, characterized in that coupled with the diaphragm.

The bracket prevents deformation of the diaphragm by the CRT by reinforcing the diaphragm having a weak rigidity due to gas injection.

On the other hand, the side of the bracket is further formed by a reinforcing plate in close contact with the speaker unit, the reinforcing plate is located between the speaker unit and the speaker can suppress the vibration of the speaker.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

In addition, this embodiment is presented by way of example only, not limiting the scope of the present invention, the same parts as the conventional configuration uses the same reference numerals or names.

Figure 2 is a perspective view showing a bracket according to the invention, Figure 3 is an exploded perspective view of the bracket and the front mask according to the invention, Figure 4 is a perspective view of FIG.

As shown, speaker portions 30 for mounting the speaker 40 are integrally formed on both sides of the front mask of the television.

In addition, an opening hole is formed in the front mask positioned between the both speaker parts 30 to expose the entire surface of the CRT.

At this time, the rear surface of the front mask is formed with a partition 31 partitioning the mounting portion of the CRT and the speaker.

The diaphragm 31 is thin due to the influence of gas injection, so the rigidity is weak.

To overcome this problem, the bracket 20 is combined with the diaphragm 31.

The bracket 20 has an insertion groove 21 for inserting the diaphragm 31 therein.

The diaphragm 31 is usually formed vertically, and the diaphragm 31 has a pair of ribs having a gap corresponding to the height of the bracket 20 so that the bracket 20 is stably mounted on the diaphragm 31. 32 is formed up and down.

In addition, guide plates 22 for contacting the ribs 32 are formed at upper and lower ends of the bracket 20.

On the other hand, the auxiliary plate 23 is protruded to one side of the bracket 20, the auxiliary plate 23 is located between the speaker unit 30 and the speaker 40.

The auxiliary plate 23 extends from the side of the bracket 20 to be integrally formed.

At this time, an elastic pad 33 may be additionally formed between the auxiliary plate 23 and the speaker unit 30.

The action and effect of the present invention made of the above structure is as follows.

When the bracket 20 is slid so that the diaphragm 31 is inserted into the insertion groove 21 of the bracket 20, the bracket 20 surrounds both sides of the diaphragm 31 to enhance the rigidity of the diaphragm 31. .

At this time, the guide plate 22 formed on the upper and lower ends of the bracket 20 is in surface contact with the rib 32 formed on the diaphragm 31 to suppress the vertical flow of the bracket 20.

On the other hand, one side of the bracket 20, that is, the auxiliary plate 23 is formed in the direction in which the speaker unit 30 is formed, the auxiliary plate 23 is located between the speaker 40 and the speaker unit 30. .

Therefore, since the speaker 40 is coupled to the speaker unit 30 via the auxiliary plate 23, the distance between the speaker 40 and the speaker unit 40 is increased than in the prior art, thereby reducing vibration.

In addition, since the pad 33 made of an elastic material is separately provided between the auxiliary plate 23 and the speaker unit 30, the vibration of the speaker 40 is suppressed.

As described above, the present invention provides a bracket for covering both sides of the diaphragm which divides the speaker unit integrally formed on both sides of the front mask, thereby increasing the rigidity of the relatively thin diaphragm due to gas injection, thereby reducing the load on the CRT. This prevents the diaphragm from deforming.

In addition, an auxiliary plate positioned between the speaker and the speaker unit is further formed on the side of the bracket, thereby increasing the coupling interval between the speaker unit and the speaker, thereby reducing vibration.

In addition, there is an advantage of further suppressing vibration by attaching a pad between the speaker unit and the auxiliary plate.
