[0002] With the advancement of home decoration technology, sound-absorbing and noise-reducing decorative panels are gradually widely used in home decoration. However, most existing decorative panels use a single sound insulation layer with an internal structure, such as only using a sound-absorbing cotton interlayer for sound insulation, or using a sound-absorbing board interlayer for sound absorption. However, the sound absorption and noise reduction effects of this single sound insulation structure are not ideal and need further improvement. Summary of the Invention

[0003] (1) Technical problems solved

[0004] The technical problem to be solved by the present invention is that most existing decorative panels adopt a single sound insulation layer with an internal structure, for example, only a sound-absorbing cotton interlayer is used for sound insulation, or a sound-absorbing board interlayer is used for sound absorption. However, the sound absorption and noise reduction effects of such a single sound insulation structure are not ideal, and further improvement is needed.

[0024] See also Figure 1-4 The sound-absorbing and noise-reducing decorative panel shown in the figure comprises a plywood core 1. The upper and lower sides of the plywood core 1 are respectively provided with an upper decorative layer 2 and a lower installation layer 3. The upper decorative layer 2 faces the interior and mainly serves as a decorative aesthetic, while the lower installation layer 3 is used to be installed on the indoor wall.

[0025] A first sound absorbing layer 4 and a second sound absorbing layer 5 are provided between the plywood core 1 and the upper decorative layer 2. The second sound absorbing layer 5 is provided between the plywood core 1 and the first sound absorbing layer 4. A first sound absorbing layer 4 and a second sound absorbing layer 5 are also provided between the plywood core 1 and the lower installation layer 3. The structures of the first sound absorbing layer 4 and the second sound absorbing layer 5 are the same. The arrangement of the first sound absorbing layer 4 and the second sound absorbing layer 5 provided between the plywood core 1 and the lower installation layer 3 is consistent with the arrangement of the first sound absorbing layer 4 and the second sound absorbing layer 5 provided between the plywood core 1 and the upper decorative layer 2.

[0026] The first sound-absorbing layer 4 comprises an aluminum foil layer 4a and symmetrically arranged first and second sound-absorbing panels 4b and 4c. The first sound-absorbing panel 4b is provided with a first sound-absorbing hole 4d, and the second sound-absorbing panel 4c is provided with a second sound-absorbing hole 4e. The end of the first sound-absorbing hole 4d, distal from the aluminum foil layer 4a, intersects and abuts the end of the second sound-absorbing hole 4e, proximal to the aluminum foil layer 4a. The aluminum foil layer 4a is disposed on a side of the first sound-absorbing panel 4b distal from the second sound-absorbing panel 4c. The first sound-absorbing hole 4d in the first sound-absorbing panel 4b and the second sound-absorbing hole 4e in the second sound-absorbing panel 4c are aligned and abutted, allowing sound waves entering the two holes to refract within them for a longer period of time. Consequently, as the sound waves propagate through the holes or gaps, they rub against air molecules within the material and the wall of the holes, generating viscous resistance. This gradually converts sound energy into heat, achieving the sound absorption effect. The inclined first and second sound-absorbing holes 4d and 4e have a longer effective length than those arranged vertically, allowing sound waves to be refracted more times, resulting in better sound absorption. The aluminum foil layer 4a utilizes its smooth surface to reflect sound waves, reducing sound penetration and thus, to a certain extent, isolating external sound from entering and enhancing indoor quietness.

[0027] Specifically, it also includes reinforcing plates 6 designed on the left and right sides of the plywood core 1 , and the reinforcing plates 6 are made of the same material as the plywood core 1 .

[0028] In this embodiment, the reinforcement plate 6 is provided to enhance the strength of the side of the entire decorative panel, thereby preventing the decorative panel from being damaged during transportation or installation.

[0029] Specifically, the aluminum foil layer 4a is made of aluminum foil and has multiple through-holes that facilitate the entry of sound waves into the first sound-absorbing holes 4d. The first sound-absorbing panel 4b and the second sound-absorbing panel 4c are both made of a material selected from among wood, wood-plastic, metal, and metal foam. The second sound-absorbing layer 5 is made of polyester fiber. The upper decorative layer 2 and the lower mounting layer 3 are both made of wood. Environmentally friendly water-based glue is used to bond the layers together, ensuring the environmental friendliness of the entire decorative panel.
