[0022] See also Figure 1-Figure 5 As shown, the technical solution adopted in this specific embodiment is: it includes a frame body 1, in which a front plate 2, a middle plate 4 and a rear plate 3 are sequentially arranged, a plurality of through holes 21 are evenly arranged on the front plate 2, a plurality of trigger devices 7 are arranged on the middle plate 4 corresponding to the through holes 21, a hole blocking seat 6 is arranged at the front end of the trigger device 7, and the shape of the hole blocking seat 6 matches the through hole 21. In this embodiment, a plurality of through holes are arranged on the front plate, and a trigger device corresponding to the through holes is arranged on the middle plate, and a hole blocking seat is arranged at the front end of the trigger device. When the hole blocking seat is pressed, the self-locking mechanism of the trigger device is used to realize the extension and retraction of the hole blocking seat, so that the through hole can be blocked or opened, thereby realizing different closed and opened combined shapes of the through hole on the front plate, and it can be combined in real time according to actual needs at any time, so as to better meet the use needs of users;

[0023] Sound insulation cotton 5 is arranged between the middle plate 4 and the rear plate 3. Filling the sound insulation cotton between the middle plate and the rear plate can better isolate the sound and achieve the effect of eliminating reverberation.

[0024] To be more specific, the hole blocking seat 6 is a transparent seat body, and the use of transparent material to make the hole blocking seat can obtain better light and shadow effects when lighting.

[0025] To be more specific, the through hole 21 is a truncated cone structure with a trapezoidal cross-section, the hole blocking seat 6 is a truncated cone structure with a trapezoidal cross-section, and the length of the hole blocking seat 6 is greater than the depth of the through hole 21. The through hole and the hole blocking seat are set as a truncated cone structure with a trapezoidal cross-section, and the length of the hole blocking seat is greater than the depth of the through hole, so as to ensure that the hole blocking seat can achieve a dustproof sealing effect by completely blocking the through hole.

[0026] To be more specific, the trigger device 7 includes a pressing rod and a seat body, and a self-locking mechanism is arranged in the seat body. In the present embodiment, a self-locking mechanism is arranged in the trigger device, and the structure of the self-locking mechanism is the same as the self-locking structure of the mobile phone memory card seat. Therefore, when the hole blocking seat is pressed, the pressing rod can be driven to trigger the self-locking mechanism in the seat body to realize the extension and retraction of the hole blocking seat, thereby facilitating the sealing of the through hole.

[0027] To be more specific, the hole blocking seat 6 is threadedly connected to the pressing rod of the trigger device. The hole blocking seat and the pressing rod are threadedly connected, which makes it more convenient to disassemble and assemble the components.

[0028] More specifically, the hole blocking seat 6 is provided with receiving grooves 61 at equal intervals along its axial direction, and corresponding decorative parts 8 are detachably embedded in the receiving grooves 61. The decorative parts can be made of various colors, so that various colors can be seen from the front to obtain better visual effects.

[0029] To be more specific, an avoidance groove 62 is provided at the opening of the accommodating groove 61, and a notch 81 is provided on the front end side wall of the decorative part 8. The notch 81 corresponds to the position of the avoidance groove 62. By providing the avoidance groove and the notch, it is more convenient to take out the decorative part for replacement, thereby obtaining more different visual effects.

[0030] Working principle of the utility model: filling sound insulation cotton 5 between the middle plate 4 and the back plate 3 can effectively filter sound and eliminate reverberation. At the same time, a plurality of through holes 21 of a truncated cone structure are arranged on the front plate 2, a trigger device 7 is arranged on the middle plate 4, and a hole blocking seat 6 is arranged on the trigger device 7. Each hole blocking seat 6 corresponds to a through hole 21. Pressing the hole blocking seat 6 triggers the self-locking mechanism in the trigger device 7, so that it can be extended and retracted, and the through hole 21 can be blocked or unblocked. Therefore, the through holes 21 in different positions can be blocked according to actual needs to achieve different combination shapes, and there will be different sound reflection effects.

[0031] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
