After fixing the ambient light 505, the filter screen cover 503 and the grille screen cover 501 with screws in sequence, the outermost grille screen cover 501 applies a force to move the filter screen cover 503 and the ambient light 505 inward to the housing 1, thereby further fastening the speaker 507 to complete the installation of the speaker 507.

[0037] As Figure 6 and Figure 7 shown, the adjusting mechanism 4 includes a sound insulation board 401, a card slot 403, a knob 404, a rotating shaft 411 and a second handle 413. The sound insulation board 401 is fixedly installed inside the housing 1. A card slot 403 is opened on one side of the sound insulation board 401. The knob 404 is meshed and connected inside the card slot 403. The rotating shaft 411 is movably sleeved on one side of the knob 404. The second handle 413 is fixedly installed on one side of the housing 1. The sound insulation board 401 is arranged on one side of the second handle 413.

[0038] The adjusting mechanism 4 further includes a first adjusting plate 41 and a second adjusting plate 42. The first adjusting plate 41 and the second adjusting plate 42 are symmetrically arranged with the sound insulation plate 401 as the center. Both the first adjusting plate 41 and the second adjusting plate 42 include a sound absorption pad 402, a first movable beam 405, a positioning beam 406, sound absorption cotton 407, a spring 408, a positioning column 409, a cable 410, a second movable beam 412 and a silicone tube 414. The sound absorption pad 402 is fixedly installed inside the sound insulation plate 401. The first movable beam 405 is fixedly installed on one side of the back plate 601. The positioning beam 406 is movably installed on one side of the back plate 601. A silicone tube 414 is fixedly installed on the top of the positioning beam 406. A positioning column 409 is movably sleeved inside the silicone tube 414. A spring 408 is arranged on one side of the positioning column 409. The top of the spring 408 is fixedly connected to the bottom of the positioning beam 406. The bottom of the spring 408 is fixedly connected to the top of the first movable beam 405. One side of the sound absorption cotton 407 is fixedly connected to the second movable beam 412. A cable 410 is fixedly connected to the top of the second movable beam 412. The cable 410 is fixedly connected to one side of the rotating shaft 411. The sound absorption cotton 407 is composed of corrugated sound insulation cotton. And the second movable beam 412 is arranged at the peak of the sound absorption cotton 407 on the first adjusting plate 41. The first movable beam 405 is arranged at the trough of the sound absorption cotton 407 on the first adjusting plate 41. The second movable beam 412 is movably installed on one side of the back plate 601.

[0039] The rotating shaft 411 is rotatably connected to one side of the sound absorption pad 402. The knob 404 is movably connected to one side of the rotating shaft 411 through a telescopic rod. And the telescopic rod is fixedly sleeved with the rotating shaft 411.

[0040] It needs to be further explained that: when it is necessary to adjust the volume of the resonance cavity inside the housing 1 to adapt to the replaced first phase inverter tube 603, first remove the second handle 413 and the screw, then manually pull out the knob 404 until the telescopic rod connecting the knob 404 and the rotating shaft 411 extends and the knob 404 disengages from the card slot 403. At this time, manually rotate the knob 404 to drive the rotating shaft 411 to rotate, and the cable 410 can be wound around the rotating shaft 411. As the number of winding turns increases, the cable 410 drives the second movable beam 412 and the sound absorption cotton 407 to gradually move towards the position of the rotating shaft 411, thereby adjusting the size of the resonance cavity between the first adjusting plate 41 and the second adjusting plate 42. At this time, the spring 408 is compressed by the positioning beam 406 and the first movable beam 405. When it is necessary to expand the resonance cavity between the first adjusting plate 41 and the second adjusting plate 42, just rotate the knob 404 in the reverse direction. Finally, when the adjustment is completed, only need to push the knob 404 back into the inside of the card slot 403, and use the engagement between the card slot 403 and the knob 404 to prevent the knob 404 from rotating to complete the fixation of the rotating shaft 411.

[0041] Working principle and use process of the utility model: During the use of the utility model, when the speaker 507 needs to be installed, the speaker 507 is first aligned with the corresponding position of the first inverted tube 603 inside the shell 1, and then the speaker 507 is fixed by screws. In the next step, the atmosphere light 505, the filter cover 503 and the grille cover 501 are aligned with the reserved slots on the shell 1 and placed. After the atmosphere light 505, the filter cover 503 and the grille cover 501 are fixed in sequence by screws, the outermost grille cover 501 applies a force to the filter cover 503 and the atmosphere light 505 to move toward the inside of the shell 1, thereby further tightening the speaker 507 to complete the installation of the speaker 507.

[0042] When the volume of the resonant cavity inside the housing 1 needs to be adjusted to match the replaced first inverted tube 603, first remove the second handle 413 and the screw, then manually pull out the knob 404 until the telescopic rod connecting the knob 404 and the rotating shaft 411 is extended and the knob 404 is out of the slot 403. At this time, manually turning the knob 404 drives the rotating shaft 411 to rotate, so that the cable 410 can be wound around the rotating shaft 411. As the number of windings increases, the cable 410 drives the second movable beam 412 and the sound-absorbing cotton 407 to gradually move toward The position of the rotating shaft 411 moves, thereby adjusting the size of the resonance cavity between the first adjustment plate 41 and the second adjustment plate 42. At this time, the spring 408 is compressed by the positioning beam 406 and the first movable beam 405. When it is necessary to expand the resonance cavity between the first adjustment plate 41 and the second adjustment plate 42, it is sufficient to rotate the knob 404 in the opposite direction. Finally, when the adjustment is completed, it is only necessary to push the knob 404 back into the slot 403. The engagement of the slot 403 and the knob 404 is used to prevent the knob 404 from rotating, thereby completing the fixation of the rotating shaft 411.

[0043] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
