[0032] Embodiment 1 provides a metal plate 1, such as Figure 1 and Figure 2 As shown, it includes a substrate 11 with multiple through holes; a non-woven fabric layer 12 disposed on the substrate 11; and a honeycomb layer 13 connected to the non-woven fabric layer 12, wherein the honeycomb layer 13 is filled with sound-absorbing particles.

[0033] The substrate 11 can be made of aluminum, which has good strength and corrosion resistance. Multiple through-holes are formed on the substrate 11, and the diameter and spacing of these through-holes can be customized according to actual needs. These through-holes facilitate the entry of sound waves, improving the sound absorption effect. A non-woven fabric layer 12 is disposed above the substrate 11. It is made of high-density non-woven fabric, which has good air permeability and sound absorption performance. The non-woven fabric layer 12 prevents sound-absorbing particles from protruding from the through-holes, thus preventing unevenness on the bottom surface of the substrate 11. It also helps in the diffusion and absorption of sound waves. The honeycomb layer 13 can be a honeycomb grid panel composed of hexagonal honeycomb units. It can be made of lightweight, high-strength materials such as aluminum alloy. The honeycomb layer 13 is tightly connected to the non-woven fabric layer 12. The honeycomb layer 13 is filled with sound-absorbing particles, which can be natural sand particles, possessing good sound absorption performance.

[0034] In one possible implementation, such as Figure 1 and Figure 2As shown, the substrate 11 includes a first plate 111, a second plate 112, a third plate 113, a fourth plate 114, and a fifth plate 115. The first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 surround the four sides of the fifth plate 115 to form a receiving groove. The fifth plate 115 has multiple through holes. The non-woven fabric layer 12 is disposed on the fifth plate 115 and is located within the receiving groove. The honeycomb layer 13 is disposed within the receiving groove, and the height of the receiving groove is equal to the sum of the height of the honeycomb layer 13 and the height of the non-woven fabric layer 12. The surface of the sound-absorbing particles is covered with an adhesive.

[0035] Multiple through holes can be machined on the fifth plate 115 using laser cutting or stamping equipment. High-density nonwoven fabric is then cut into sheets of the same size as the fifth plate 115. An adhesive is used to evenly adhere the nonwoven fabric layer 12 to the top of the fifth plate 115, ensuring a tight bond between the nonwoven fabric layer 12 and the fifth plate 115.

[0036] In the specific implementation process, the first plate 111, the second plate 112, the third plate 113, the fourth plate 114 and the fifth plate 115 are integrally formed. For example, the four sides of an aluminum plate can be bent to form a receiving groove. Non-woven fabric is laid at the bottom of the receiving groove, and the area of ​​the non-woven fabric is the same as the area of ​​the bottom of the receiving groove. Then, the honeycomb grid is placed into the receiving groove. Before placing the sound-absorbing particles into the honeycomb grid, the particles need to be screened and cleaned to remove impurities and unsuitable particles. The sound-absorbing particles and binder are added to a mixer in a certain proportion and thoroughly mixed to ensure that the particle surface is evenly covered with a layer of binder, such as epoxy resin, accelerator, and curing agent. The mixed material is then placed into the honeycomb grid, and the entire metal plate 1 is placed into a mold. It is then shaped into a sound-absorbing board blank through vibration and pressure. The shaped sound-absorbing board blank is placed in a curing oven and cured at a certain temperature and time to fully cure the binder, thereby enhancing the strength and stability of the sound-absorbing board. After demolding, the sound-absorbing board is trimmed, polished, and cut to obtain a sound-absorbing board product that meets the requirements.

[0037] Example 2 provides a mounting structure for a metal plate 1, such as... Figure 3 , Figure 4 , Figure 5 and Figure 5As shown, the metal plate 1 mentioned above also includes: a first connector 2, a second connector 3, a third connector 4 and a fourth connector 5. The first connector 2 passes through the second connector 3 and is connected to the honeycomb layer 13. The third connector 4 is connected to the second connector 3. The third connector 4 is connected to the fourth connector 5. The fourth connector 5 is also used to connect to the keel 7.

[0038] In one possible implementation, the second connector 3 includes a first connecting portion 31 and a second connecting portion 32, the first connecting portion 31 and the second connecting portion 32 are connected, and the first connector 2 passes through the second connector 3 to connect with the honeycomb layer 13, including: the first connector 2 passes through the first connecting portion 31 to connect with the honeycomb layer 13, and a protrusion 33 is provided on one side of the second connecting portion 32, the protrusion 33 being connected with the third connector 4.

[0039] Among them, such as Figure 4 As shown, the first connector 2 can be a dovetail screw, and the second connector 3 can be a connecting angle aluminum. One end of the dovetail screw passes through the first connecting portion 31 of the connecting angle aluminum and is inserted into the honeycomb layer 13. A protrusion 33 is provided on one side of the second connecting portion 32 of the connecting angle aluminum. To make the connection between the dovetail screw and the metal plate 1 more secure, such as... Figure 4 As shown, the right side of the metal plate 11 is bent, with part of the plate bent above the honeycomb layer 13. In this way, one end of the dovetail screw passes through the first connecting part 31 of the connecting angle aluminum and part of the plate and is inserted into the honeycomb layer 13, making the connection between the dovetail screw and the metal plate 1 more stable.

[0040] In one possible implementation, such as Figure 6 and Figure 7 As shown, the connection between the protrusion 33 and the third connector 4 includes a bending portion 41, which engages with the protrusion 33. The third connector 4 also includes a snap-fit ​​portion 42. The bottom of the fourth connector 5 has a slot 51, and the snap-fit ​​portion 42 engages with the slot 51.

[0041] In the specific implementation process, the second connector 3 is fixed to the edge of the metal plate 1. When the sidewalls of the two metal plates 1 are in contact, such as Figure 7 As shown, the second connecting portions 32 of the second connectors 3 of the two metal plates 1 are also attached, the two protrusions 33 are opposite to each other, and the bent portion 41 of the third connector 4 forms a shape similar to a circle, with the two protrusions 33 located in the middle of the circular bent portion 41, and the two protrusions 33 abutting against the bottom wall of the circular bent portion 41. In this way, the two metal plates are hung together by a third connector 4, as shown. Figure 7As shown, the bottom of the fourth connecting part is provided with a slot 51, and the top of the third connecting member 4 is a snap-fit ​​part 42. The snap-fit ​​part 42 is adapted to the slot 51, thereby snapping the third connecting member 4 and the fourth connecting member 5 together.

[0042] In one possible implementation, such as Figure 6 and Figure 7 As shown, it also includes a hanger 6, one end of which is used to connect to the keel 7, and the other end of which is used to connect to the wall or ceiling. A cavity is formed between the metal plate 1 and the wall, or between the metal plate 1 and the ceiling.

[0043] In the specific implementation process, such as Figure 6 As shown, one end of the fourth connector 5 is connected to the keel 7 by a rivet, and the hanger 6 is fixed to the ceiling or wall by an expansion screw. At this time, a cavity is formed between the metal body and the wall or ceiling.

[0044] In summary, in this embodiment, the sound absorption principle of the metal plate 1 (sound-absorbing plate) mainly includes porous sound absorption and co-absorption. When sound waves are incident on the surface of the substrate 11, they penetrate into the interior of the plate and propagate through the fine pores. Due to the viscosity and frictional resistance generated by air movement, the sound energy is gradually converted into heat energy and consumed, thus producing a sound absorption effect. A cavity is provided behind the metal plate 1. When sound waves enter the cavity, they are reflected back and forth within the cavity, increasing the propagation distance of the sound waves and thus improving the sound absorption effect. At the same time, the air inside the cavity also resonates with the sound waves, further enhancing the sound absorption effect.

[0045] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
