Description of the invention (3) This will be added later The program of the pro-yang system. The speaker used to assemble the conventional technology is tied to the speaker of the front cover 6. The screw holes at the four corners of the 2 ^ 6 0 0 match the frame bundle of the speaker 100a. In the case of the speaker binding screw 70Ux, it starts from the screw binding hole 602. According to this method, the d ::: and Yang: device 1 is called the cymbal mounted on-and comes into close contact with the speaker, which leads to the sound of direct forward sound. Two directly backward Mao Lei m η 丄 + FREE Today's wear and tear. After the front cover 6 and the speaker 1 0 0 a are connected together, the back cover strikes the monument & η Λ Λ ^ # 9y., '' 専 累 、 ', 糸 7 〇2 screw holes 2 0 6, and the assembly 刖 benefit 6 and the back cover 2 together, this Japan You Xiong # 士 a # 0 This is the back cover binding protrusion 602 on the 盍 6 matching the rear Screw holes on cover 2. 钬 你 ^ _DU ^ ^ Then, screw the screw 703 through the opening 60Q into the speaker system restraining projection 4 nq ^ ^ ^ ^ inch big life 403 'At this time in the compartment 4 The speaker system restrains the protruding surface 4 0 3 and the perforation 6 0 9 (for the perforation in the representative front cover 6) at the position n Qtb. * Λ ^ ^, bit 6 0 8 to match the speaker system. The speaker system that is bound to the compartment 4 but used in the conventional technology for display has the following problems caused by structural limitations. ^ t W η The beneficial & vocal system requires a rather complex shape of the front panel 6, which has multiple < ^ ηΓι1_ ^ 1U large surface 605, 606 media to tie the speaker 10 0a to the resonance box 2. Top. You can use the front cover 6 as the medium mechanism. When installing the speaker system of the conventional technology to the compartment ^ # ρ 相 阳 间 4, you must not fail to provide a perforation 6 6 8 . Because of the strong position, the speaker system in the conventional technology has many defects in the components. This & from, Λ α, dl, L ,, and the components must have a relatively complicated shape. , $ = Two increase ', and the productivity of these components during manufacturing and assembly are reduced T. In the conventional technology, the complicated shape is required before the cover sounds.

448 69 6 V. Description of the invention (4) Multiple components are required, and multiple binding components are required during assembly. For this reason, the speaker system of this conventional technology has multiple cost drivers, is quite difficult in component manufacturing, and requires a considerable amount of manpower to produce greens. In particular, the required distance between the inner surface of the outer side wall surface of the front cover 6 and the outer surface of the speaker 100a (" A " in Fig. 4) will affect the design and material cost. That is, the distance between the outer side wall surface and the inner surface of the front cover 6 and the outer surface of the speaker 100a (MA "in FIG. 4) must require that there should be no failures in the assembly of the front cover 6 and the rear cover 2, In order to provide a rear cover restraining projection 606, it can be used to assemble the rear cover 2 into the outer area of the speaker 100. For technical reasons, the distance " A "must be fixed to the inner surface of the outer side wall surface of the front cover 6 and Between the outer surfaces of the speaker 100a, the width of the front cover 6 (MC " in Fig. 4) becomes wider than the width of the speaker frame 600 ("" in FIG. 4). To be more precise Compared with the width of the frame 600, the width of the front cover 6 (same as the width of the rear cover) is greater than twice the thickness of the front cover, which will double the gap " A " in Figure 4. At the same time, in this In the speaker system, a space is provided between the inner surface of the compartment 4 and the outer surface of the Brown tube. Therefore, the speaker system is used to place the speaker system between the outer surface of the compartment 4 and the outer surface of the Brown tube. Spacing (" D " in Figure 5) must be as large as the technology The cover inside surface of the outer wall 6, and a speaker 100 Room outside surface of a pitch (in FIG. 4 " A ") of the size, design and this will affect the cost of the speaker system. Meanwhile, the symbol M F in FIG. 5 is the width of the monitor of the conventional speaker system. This leads to another problem of the speaker system for displays in the conventional technology. Although in the design the rear cover of the front cover 6 fits the surface 6 0 4

4 4 8 6 9 6_____ V. Description of the invention (5) The front cover fitting surface 2 of the rear cover 2 is in close contact to prevent the sound of the sound directly bound forward from affecting the sound that leaks directly backward, but due to the close contact with the surface The distance between them cannot completely block the sound directly leaking back, which causes the loss of the sound pressure of the direct forward sound. Consider the rear cover fitting surface 6 0 4 of the front cover 6 and the rear fitting surface 2 0 8 Full close contact cannot be achieved. When a sound leaks backward, it will lead to a problem, that is, the pressure of the sound that is directly forward is lowered by the sound that is directly downward, because the phase of the backward sound is opposite to that of the directly forward sound. The speaker system for a display in the conventional technology has another problem. . Now on the 100a side, the direct sound effect from this channel is deteriorated. When the quality deteriorates, a sound will reduce the vibration in the technology, and the tube will be connected to the cloth. The wear-specific will be placed by the screw 'Guide' so that the shielding in the tube is shown in Figure 3. In the speaker system of the conventional technology, the speaker cover ^^ is bound to form a sound wave channel with a certain length, to the front cover 6 The front surface of the speaker makes it possible for sound emitted from the speaker i 〇a to pass through this channel during speaker operation. At this time, the sound will produce a tunneling effect for the sound transmitted directly forward from the speaker 100. The sound tunnel effect of the sound transmitted directly forward from the speaker 100 is a phenomenon, where the sound when the sound passes the frequency of the channel will be compensated , And another-the specific frequency is large, which hinders the sound quality required for configuration. Moreover, the conventional ‘rigid body’ delays the conventional technique ^ &# π ^ ± junction compartment 4 without fading, so that the image produces a severe flash of nitrogen, and then is transmitted to: ^ x ^ Chen phenomenon. That is, the vibration is directly transmitted to the mask :: Vibration and the inner surface of the Brown tube produce 6 胄 ', which causes the image to flash. Moreover, the above

Page 8 V. Description of the invention (6) The problem will result in the inability to provide high-power speakers, especially the inability to lower the low frequency band further, resulting in deterioration of sound quality. The image flickering at 2000 Hz will be quite serious. This prevents a high-quality speaker system from being built into the display. SUMMARY OF THE INVENTION Therefore, the present invention relates to a compartment for a display, 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 speaker system for a display, in which the number of components can be reduced, thereby saving production costs, and improving the productivity during component manufacturing and assembly, so that the ratio of the short axis to the long axis of the speaker can be reduced. Made close to I: 1 to improve sound quality. Another object of the present invention is to provide a speaker system for a display, which prevents pressure loss of a sound direct vector caused by using sound directly leaking backward, and improves sound deterioration due to a tunneling effect. Another object of the present invention is to provide a speaker system for a display which prevents flickering of an image on the display due to vibration from the speaker to the compartment when the speaker is operated.

Further, the speaker system of the present invention has an edge 10 3 and a spacer 102 attached to a cover frame having an attachment member, and the width of the spacer 10 2 is the same as the width of the cover frame combined speaker 1 (" in FIG. 9A W "). Therefore, if it is assumed that in the speaker system of the present invention, the width of the monitor is the same as that of the speaker system of the conventional technology, the width of the front frame is the same as the width of the front frame of the conventional technology, and sound is actually emitted. The width of the speaker 100 can be made much larger than the short diameter of the speaker in the speaker system of the prior art. That is, the short diameter of the speaker 100 can be twice the width " An of the conventional technology in Fig. 4 (A is the distance between the inner surface of the outer sidewall and the outer surface of the speaker 100). This implies that the ratio of the short diameter to the long diameter of the speaker system can be made closer to 1: 1. Therefore, if the other cases are the same, the configurable sound quality of the speaker system for a display in the first embodiment may be better than that of a speaker system for a conventional technology of a body. The speaker system used in one of the displays of the present invention has the following advantages. First, because the speaker system used for the display of the present invention is quite cost-effective, and can be assembled with high quality to prevent pressure loss of the sound directly forward caused by the sound leaking directly backward, high sound quality and low Noise speakers. That is, because the speaker system of the present invention does not require a front cover, that is, a medium for vibrating the speaker 100 and the rear cover 2 is not required, the display can reduce the cost of the speaker system, and improve the productivity of component manufacturing and assembly. Moreover, the front cover is not used in the speaker system of the present invention, but is allowed to be used.
