The field of invention of the present invention relates to a speaker system for a video display device, especially a speaker for a video display device. The system has a multi-resistance and noise device, which is in the first damping component and the video display device. It can have an improved multiple damping structure, so a low vibration and high-quality sound can be obtained. Known technical description | | Designed as a video monitor for a computer monitor that can be placed into a speaker system | No equipment 'to assemble the speaker system with the outer wall surface of the Brown tube and the inner side suitable for surrounding the Brown tube | As shown in Figure 1. Therefore, you can understand that the size of the speaker system depends on the width of its assembly space.

I In addition, the size of the speaker system defines the short diameter of the speaker system and the ratio between the short diameter and its long diameter.

Description of the invention (2) —— 颏 Power, which will be explained in the order rK, Λ ^ ^ Jt_ and the traditional speaker system for video display equipment, please refer to the attached drawings 1 to 3. The perspective view of FIG. 2 illustrates the speaker system of FIG. 1 and its damping device, and the perspective view of FIG. 3 illustrates the assembled state of FIG. 2. As shown in Figures 1 and 2: 'Traditional Trajectory Shaper System Package 3 for Video Display Equipment: 2 with a cover 1001 and a speaker 100 for sound production, the two are integrated with each other. :-Assemble the damping assembly with the poor combination of the protruding cover and the cover-type speaker to assemble a damping assembly adaptation site 200 at the rear and below, and-the damping assembly 3 of the structural extension damping assembly adaptation site. Closing cover _ at the person ^ η The vibration generated by the combined speaker 1 and the rear cover 2 during the operation of the partition m 'h 扬 u # can be damped and sent to the compartment 4. w At this time, the speaker 100 includes a washer 102, a ring-shaped end 103 connected to the inside of the washer, and a conical paper 丨 connected to the inside of the end 10. On the other hand, the damping component 3 includes a hollow cylindrical body part 300. The peripheral surface of the body part includes a plurality of cutting grooves 301, and the diameter of one end of the plurality of cutting grooves forming the body part: The edge part 302, where a plurality of cutting grooves 301 of the body part 300 are formed, and the other end of the plurality of cutting grooves 301 of the body part 300 are formed with a convex piece 304.仫 Upward formation of a structure of the damper of the vocal system and its operation will be described below under the structure described above. First, in the case that the cover frame is combined with the plastic speaker 1 and the rear cover 2 is mounted, such as 448699 V. Description of the invention (3) 二者 2 Both P and Ni component 3 are inserted on the cover 2 and damped respectively , Pieces adapted to site 2. . The damping component adapts to the hole 02 () 1. Herein, after the body part 300 of the wide damping component 3 is completely inserted into the damping component adapting opening 2 01, the damping component 3 is made of 苴 太 | ^ material. The knot 1 'is located at the other end of the body portion side where the cutting groove 3 () 1 is formed ^ The convex member 304 is positioned behind the damping component adapting portion 200 to prevent the damping component 3 from shifting. b Therefore, when the body system 300 of the damping assembly 3 installed on the speaker 00 is positioned over the speaker system adapting protrusion 400 formed on the compartment 4, the speaker system adapts the protrusion 400. It shall be secured with a washer-based screw 6. The flange portion 302 of the damping component 3 is used to prevent direct contact between the positioning rib 401 and the damping component adaptation portion 2000. In the above-mentioned state, 'on the other hand, the conventional damping device is used to reduce the vibration generated during the operation of the speaker system through the material characteristics and the geometry of the damping component 3, which can be removed in the video display device I. Screen flickers. However, since the speaker system of the conventionally structured video display device performs vibration damping operation only once, there is a problem that there is no way to completely damp the vibration transmitted to the compartment 4. If a large amount of vibration that is not damped by the damping component 3 is transmitted to the compartment | 4 'and thus the video display device that is finally transmitted to the Brown tube, the mask installed on the inner side of the Brown tube generates spectral vibrations, so a glittering 448699 I V. Description of the Invention (4) | In other words, when flicker due to insufficient damping, the speaker system cannot press the sound pressure above a predetermined value, and expands the bandwidth at low pass. The result is that traditionally used speaker systems cannot reduce the speaker's wattage 'considering incomplete damping, especially in the frequency band below 2000 Hz, there is a rather severe damping phenomenon in the sound. As a result, it is not possible to reduce the frequency band to obtain a low sound, and thus the sound quality is degraded, which of course leads to a practical deterioration of the quality of the speaker system. SUMMARY OF THE INVENTION Therefore, the present invention relates to a multiple damping device for a speaker system of a video display device, which can actually solve one or more problems caused by the disadvantages of the limitations of the conventional technology. An object of the present invention is to provide a multiple damping device for a speaker system of a video display device, which can pass vibrations generated during the operation of the speaker system through a multiple damping path, thereby preventing the vibration in the video display device from being transmitted to the compartment due to vibration The resulting screen flickers, so the speaker system can produce a high watt output 'and ensure that the frequency band can be extended at low pass. In order to establish the above and other objects of the present invention, the present invention provides a multiple damping device for a speaker system, which is used in a video display device with a cover-mounted type! Speaker to generate sound in the cover-mounted type | A rear cover is assembled at the rear of the speaker, and a damping component adapting part is installed above and below it, respectively, and a damping component is adapted to insert the damping component to adapt to the damping of the opening.
