[0002] The grille decorative panels in the prior art are usually composed of a simple flat plate or a structure with a small amount of sound-absorbing material. Although these designs are relatively simple in production and installation, they lack effective sound-absorbing and sound-absorbing structures, resulting in limited noise reduction effects in practical applications. In particular, for occasions requiring high noise reduction effects, the grille decorative panels in the prior art often cannot meet the requirements. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a grille decorative plate, which forms a hybrid silent structure by setting a dot matrix hole, a silencer cavity and a sound absorbing plate, thereby significantly improving the silent effect. Specifically, the dot matrix hole penetrates and connects the silencer cavity and the sound absorbing plate, so that the sound is reflected and absorbed multiple times during the propagation process, further reducing the noise.

[0005] Furthermore, the fixing plate and the sound absorbing plate are bonded and formed into one piece.

[0006] Furthermore, the diameter of the lattice holes is 0.5-2 mm.

[0007] Furthermore, the length direction of the grille plate is parallel to the length direction of the sound absorbing plate.

[0008] Furthermore, the depth of the groove is 2-5 mm.

[0009] Furthermore, the fixing plate and the silencing cavity are integrally connected.

[0010] Furthermore, the lattice holes are arranged in a matrix form.

[0012] The beneficial effects achieved by the utility model using the above structure are as follows:

[0013] The present invention achieves a significant improvement in the mute effect of the grille decorative plate through reasonable structural design. By setting up lattice holes, muffler cavities and sound-absorbing panels, a hybrid mute structure is formed, which not only improves the practical application value of the decorative plate, but also provides a more effective solution in situations with high mute requirements. In particular, through the mutual cooperation of the grooves, lattice holes, cavities and muffler cavities, the sound can be fully absorbed and attenuated during the propagation process, significantly reducing noise and improving the mute effect of the environment.

[0020] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Specific embodiment:

[0024] like Figures 1 to 5 As shown, the grille decorative plate includes a grille plate 1 and a sound absorbing plate 2. The grille plate 1 is mounted on the sound absorbing plate 2. The grille plate 1 includes a groove 101, a lattice hole 102, a cavity 103, a muffler cavity 104 and a fixing plate 105. The muffler cavity 104 is fixed on the fixing plate 105. The muffler cavity 104 includes a cavity 103. The groove 101 is arranged between adjacent muffler cavities 104. The lattice hole 102 penetrates and connects between the cavity 103 and the groove 101.

[0025] like Figure 1 and Figure 2 As shown, the fixing plate 105 is bonded and integrally formed with the sound absorbing plate 2. This integrally formed design improves the overall structural strength and installation convenience.

[0026] like Figure 3 As shown, the diameter of the dot matrix holes 102 is 0.5-2 mm. Such an aperture design helps to improve the sound-absorbing effect of the grille plate, so that the sound can be effectively absorbed and attenuated when passing through the aperture.

[0027] like Figure 1 As shown, the length direction of the grille plate 1 is parallel to the length direction of the sound absorbing plate 2. This design can ensure the consistency and integrity of the grille plate and the sound absorbing plate during use, and improve the aesthetics and functionality.

[0028] like Figure 2 As shown, the depth of the groove 101 is 2-5 mm. Appropriate groove depth can improve the sound-absorbing effect while maintaining the stability and strength of the structure.

[0029] like Figure 2 and Figure 3 As shown, the fixing plate 105 is integrally connected to the muffler cavity 104. This integrally connected design enables the grille decorative plate to have better structural stability and durability.

[0030] like Figure 2 As shown, the dot matrix holes 102 are arranged in a matrix form. The matrix arrangement can evenly distribute the sound and further reduce the noise through multiple reflections and absorptions.

[0031] like Figure 3As shown, the silencing cavity 104 is semicircular. The semicircular silencing cavity structure helps multiple reflections and absorption of sound, thereby achieving a better silencing effect.

[0032] like Figures 1 to 5 As shown, the sound is transmitted through the dot matrix holes 102, part of the sound cancels each other out in the muffler cavity 104, and the other part of the sound is absorbed by the sound absorbing board 2. Such a design enables the sound to be reflected and absorbed multiple times during the propagation process, thereby significantly reducing the noise and improving the overall mute effect.

[0033] This design effectively solves the problem of limited sound-absorbing effect of grille decorative panels in the prior art, and is particularly suitable for occasions requiring high sound-absorbing effect, such as conference rooms, recording studios, and high-end residences.

[0034] Through the structural design of this grille decorative plate, the utility model not only improves the sound-absorbing effect, but also provides a more effective solution in practical applications, significantly improving the market competitiveness of the product. It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article or device.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0036] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
