Description

TV front mask vibration damper

The present invention relates to a front mask anti-vibration device that can prevent the front mask vibration caused by the vibration of the speaker installed in the front mask of the television, in particular, the speaker grille is installed on both sides of the front mask of the television, respectively. In the rear of the speaker grille, a box-shaped speaker bracket in which a speaker hole is installed in the front of which the speaker is installed is located, and a plurality of engagement piece coupling holes are formed in the front circumference of the speaker bracket and protrude on the rear of the front mask. Hook-type locking piece is to be interpolated.

Accordingly, by installing a separate speaker bracket with a built-in speaker on both sides of the front mask on which the TV's CRT is installed, it prevents vibration of the front mask and CRT due to the speaker's operation and prevents screen shaking. Of course, the present invention relates to a front mask anti-vibration device of a television, which enables the speaker bracket to be easily and easily coupled to the back of the front mask without the need for a separate fastener.

In a conventionally known combination of television speakers, as shown in Figs. 1 and 2, the speaker grill 32 is installed below or in front of the front mask 31 of the television. The rear side of the front mask 31, which is the rear of the grill 32, is integrally provided with a support bracket 34 provided with a speaker coupling hole 33 so as to couple and fix the speaker 36 as a screw 35. Is done.

In the conventional TV speaker having such a coupling structure, as shown in FIG. 2, after the support bracket 34 having a rectangular shape is provided as a single injection molding on the rear surface of the front mask 31 on which the speaker grill 32 is installed, The support bracket 34 is to be fixed to the speaker 36 as a screw 35.

However, when the speaker 36 mounted on the rear surface of the front mask 31 is operated, vibration generated from the speaker is transmitted to the front mask 31 by the support bracket 34 and the front mask 31. The CRT which is fixed thereto by the vibration of the panel also has a disadvantage in that vibrations are generated, causing the screen to shake.

In addition, since the speaker 36 of the television is fixed to the rear surface of the front mask 31 by using a separate fastener such as a screw 35 or the like, the speaker assembly and maintenance work are difficult. will be.

The present invention has been made to improve the various problems as described above, the purpose is to install a separate speaker bracket with a built-in speaker on both sides of the front mask on which the CRT of the TV is installed, according to the operation of the speaker It prevents the vibration of the front mask and CRT in advance, prevents screen shaking, and the front of the TV can be easily and easily coupled to the back of the front mask without the need for a separate fastener. It is an object of the present invention to provide a mask vibration preventing device.

As a technical configuration for achieving the above object, the present invention, the speaker grille is installed on both sides of the front face of the front mask of the television, the rear of the speaker grille, the speaker hole in the front, and the speaker inside An inner box-shaped speaker bracket is located, and the front edge of the speaker bracket is provided with a plurality of engaging piece engaging holes in the front, and the hook-shaped locking piece protruding from the front mask is interposed to fix the front mask of the TV. By providing a device.

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

3 is an exploded perspective view of a box-shaped speaker bracket installed on a front mask of a television according to the present invention, and FIG. 4 is a side cross-sectional structural view of a coupled state of a speaker for preventing vibration of the front mask of the present invention. The speaker grilles 2 are respectively installed at both sides of the front mask 1 in front, and the speaker 6 is coupled to the rear of the speaker grilles 2.

On the rear surface of the front mask 1 on which the speaker grill 2 is mounted, a speaker hole 3 is installed in the front, and a box-shaped speaker bracket 4 in which the speaker 6 is built is located. At the front circumference of the speaker bracket 4, a plurality of locking piece coupling holes 5 are laid so as to engage and fix the hook type locking piece 7 protruding from the rear surface of the front mask 1.

In addition, the speaker bracket 4 has a configuration in which a cushioning material 8 for preventing vibration of the front mask 1 is installed at its front circumference.

Referring to the operation and effects of the present invention composed of such a structure as follows.

As shown in FIGS. 3 to 4, the speaker 6 installed in a state in which the front mask 1 of the television is installed is in a state in which speaker grills 2 are respectively installed on both sides of the front mask 6. In this case, the speaker 6 is coupled to the rear of the speaker grill 2. The front mask 1 on which the speaker grill 2 is mounted is provided with a box-shaped speaker bracket 4 on which a speaker hole 3 is laid on the rear surface thereof, and a speaker 6 therein. do. In this case, a plurality of engagement piece coupling holes 5 are formed at the front circumference of the box-shaped speaker bracket 4, and a hook-type locking piece 7 protrudes inward in the rear surface of the front mask 1 to be coupled thereto. To be installed.

Accordingly, in the speaker bracket 4 in which the speaker 6 is installed, the hook-type locking piece 7 is engaged with the locking piece coupling hole of the speaker bracket 4 by pushing the rear side of the front mask 1. 5) By inserting the speaker 6 through the separate box-shaped speaker bracket 4 so that the speaker 6 is not directly installed in the rear of the front mask 1 by being tightly inserted and fixed in the speaker. The vibration of the front mask 1 according to the driving of the almost is prevented.

In addition, the speaker bracket 4 comes in contact with the rear surface of the front mask 1 by mounting the cushioning material 8 for preventing vibration of the front mask 1 at its front circumference. The cushioning material 8 is brought into contact with the contact surface of 4) so that vibration of the speaker can be more reliably blocked.

As described above, according to the apparatus for preventing front mask vibration of a television according to the present invention, a separate speaker bracket with a built-in speaker is installed on both sides of the front mask on which the TV's CRT is installed, so that It prevents the occurrence of vibration in advance and prevents the shaking of the screen, and the speaker bracket is easily and easily coupled to the back of the front mask without the need for a separate fastener, and thus the installation and maintenance of the speaker There is an excellent effect that can be improved.
