Description

Technical Field

[0001] This utility model relates to the field of decorative panel technology, specifically to a sound-insulating decorative panel. Background Technology

[0002] With urban development, people are paying more and more attention to the quality of their living environment, making sound insulation and noise reduction of decorative panels particularly important in architectural design.

[0003] 1. Existing sound insulation panels may have regular cavities that are regularly distributed. In an acoustic environment, regular cavity distribution can easily cause sound waves of certain frequencies to resonate, which in turn can lead to abnormal amplification of sound at certain frequencies.

[0004] 2. Because the sound insulation board is made of a single material, it cannot absorb sound waves of different frequencies, resulting in fewer sound absorption frequency bands and poor absorption effect of the decorative board on different frequency bands of sound.

[0005] 3. The sound insulation panels in existing decorative panels are flat, the propagation pattern of sound waves is relatively simple, and the sound waves have few opportunities to come into contact with the sound-absorbing material, resulting in low sound absorption efficiency and poor sound insulation effect of the decorative panels. Utility Model Content

[0006] To address the above problems, this utility model provides a sound-insulating decorative panel, which solves the aforementioned issues.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sound-insulating decorative panel, comprising a panel body, the panel body comprising a decorative panel and a base plate, a sound-insulating panel connected between the decorative panel and the base plate, the sound-insulating panel comprising a front sound-insulating panel and a rear sound-insulating panel, and a plurality of corresponding cavities being formed on one side of both the front sound-insulating panel and the rear sound-insulating panel.

[0008] The plurality of cavities are irregularly shaped, and the plurality of cavities are irregularly distributed on the front sound insulation panel according to their shapes;

[0009] A sound insulation board is connected between the decorative panel and the substrate. The sound insulation board includes a front sound insulation layer, a middle sound insulation layer, and a rear sound insulation layer. One side of the front sound insulation layer is connected to one side of the substrate. Several large holes are opened on the front sound insulation layer.

[0010] The middle sound insulation layer has several central holes, and the rear sound insulation layer has several small holes. One side of the rear sound insulation layer is connected to one side of the decorative panel.

[0011] Preferably, a slot is provided on one side of the substrate, and a sound-insulating folding plate is provided between the decorative panel and the substrate.

[0012] Preferably, the sound-insulating folding plate is W-shaped, and the apex angle of the sound-insulating folding plate is degrees.

[0013] Preferably, the upper and lower ends of the soundproof folding plate are fixedly connected to mounting plates, and the mounting plates are provided with positioning holes, which correspond to the slots.

[0014] Preferably, the sound-insulating folding plate forms several equilateral triangles with the decorative plate and the substrate.

[0015] Preferably, a plug is fixedly connected to one side of the decorative panel, and a positioning ring is fixedly connected to the outside of the plug.

[0016] Preferably, the outside of the insertion rod is inserted into the inside of the positioning hole and the slot, and the positioning ring is disposed on one side of the mounting plate, and the positioning ring presses the mounting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This application uses a cavity formed by the front sound insulation panel and the rear sound insulation panel in combination with the cavity groove. The irregular distribution of the cavity groove can break the propagation law of sound waves, so that the sound waves undergo a more complex and chaotic propagation path in the sound absorption panel, which solves the problem of low sound absorption efficiency of decorative panels and is conducive to improving the sound absorption efficiency of decorative panels.

[0019] 2. This application, through the combination of front, middle, and rear sound insulation layers with decreasing pore size, enables decorative panels to specifically absorb sound waves of different frequencies, thereby broadening the sound absorption frequency band and solving the problem of poor sound absorption of different frequency bands by decorative panels. This is beneficial to improving the sound absorption effect of decorative panels on different frequency bands.

[0020] 3. This application uses sound-insulating folded plates to form relatively complex reflection and scattering paths, which increases the contact opportunities between sound waves and sound-absorbing materials, solves the problem of poor sound insulation effect of decorative panels, and helps to improve the sound insulation performance of decorative panels.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] Example 1: Please refer to Figure 1 , Figure 2 A sound-insulating decorative panel includes a panel body, which includes a decorative panel 1 and a base plate 4. A sound-insulating panel is connected between the decorative panel 1 and the base plate 4. The sound-insulating panel includes a front sound-insulating panel 15 and a rear sound-insulating panel 16. Each of the front sound-insulating panel 15 and the rear sound-insulating panel 16 has several corresponding grooves 17 on one side. In use, the front sound-insulating panel 15 and the rear sound-insulating panel 16 are connected together by adhesive. The front sound-insulating panel 15 and the rear sound-insulating panel 16 cooperate with the grooves 17 to form a cavity. Due to the irregular shape of the cavity, after the sound waves enter the interior of the sound-insulating panel, they will undergo extremely complex reflection and scattering in these cavities with different shapes. Compared with regular cavities, irregular cavities make the propagation path of sound waves disordered and unpredictable. This greatly increases the contact opportunities between sound waves and the cavity walls and the internal sound-absorbing materials, so that the sound wave energy can be consumed more fully, thereby significantly improving the sound insulation panel's sound blocking and absorption effect.

[0030] It should be noted that both the front sound insulation panel 15 and the rear sound insulation panel 16 are made of glass wool, and the cavity 17 is filled with sound-absorbing cotton, which can further improve the sound absorption performance of the sound insulation panel.

[0031] The cavity 17 is irregularly shaped and is irregularly distributed on the front sound insulation panel 16. In an acoustic environment, a regular cavity distribution can easily cause sound waves of a certain frequency to resonate, which in turn leads to abnormal amplification of sound at certain frequencies. The irregular cavity of this application can disrupt the reflection path of sound waves, avoid the formation of fixed resonance conditions, and reduce the occurrence of harmful resonance.

[0032] Example 2: Please refer to Figure 3 , Figure 4A sound insulation board is connected between the decorative panel 1 and the substrate 4. The sound insulation board includes a front sound insulation layer 9, a middle sound insulation layer 11, and a rear sound insulation layer 13. One side of the front sound insulation layer 9 is connected to one side of the substrate 4. Several large holes 10 are opened on the front sound insulation layer 9. The materials of the front sound insulation layer 9, the middle sound insulation layer 11, and the rear sound insulation layer 13 are all glass wool. The glass wool of the rear sound insulation layer 13 is relatively denser. The front sound insulation layer 9, the middle sound insulation layer 11, and the rear sound insulation layer 13 are distributed adjacent to each other, so that the large holes 10 absorb low-frequency sound waves better, and the small holes 14 absorb high-frequency sound waves better.

[0033] From the outer layer to the inner layer of the sound insulation panel, the size of the holes gradually decreases, which allows the sound insulation panel to absorb sound waves of different frequencies in a targeted manner. The large hole 10 first absorbs and scatters low-frequency sound waves, the medium hole 12 further absorbs mid-frequency sound waves, and the small hole 14 is mainly responsible for absorbing high-frequency sound waves, thereby broadening the sound absorption frequency band and improving the absorption effect of different frequency bands of sound.

[0034] Furthermore, the decreasing aperture structure allows sound waves to undergo multiple reflections, refractions, and absorptions within the sound insulation board. When sound waves enter the sound insulation board from the outer layer, they encounter apertures of different diameters, which continuously change their propagation direction and speed, gradually consuming energy. Moreover, this structure effectively prevents sound waves from directly penetrating the sound insulation board, thereby significantly reducing the propagation of indoor and outdoor sound and improving the noise reduction effect of decorative panels.

[0035] The middle sound insulation layer 11 has several central holes 12, and the rear sound insulation layer 13 has several small holes 14. One side of the rear sound insulation layer 13 is connected to one side of the decorative panel 1. When assembling the decorative panel, the front sound insulation layer 9, the middle sound insulation layer 11, and the rear sound insulation layer 13 are installed by adhesive bonding.

[0036] Example 3: Please refer to Figure 5 , Figure 6 A slot 5 is provided on one side of the substrate 4, and a sound-insulating folding plate 6 is provided between the decorative plate 1 and the substrate 4.

[0037] The sound insulation folded plate 6 is W-shaped with a 60-degree apex angle. The material of the sound insulation folded plate 6 is glass wool. The W-shape also allows sound waves to form a more complex reflection and scattering path between the sound insulation folded plates 6. Furthermore, the sound waves are reflected multiple times within the structure of the sound insulation folded plate 6, increasing the contact opportunities with the sound-absorbing material. This more effectively dissipates sound wave energy and improves the sound absorption effect. At the same time, compared with a flat sound insulation board, the sound insulation folded plate 6 forms multiple planes through bending, allowing more sound-absorbing material surface to be exposed for the same volume of sound insulation board, allowing more sound waves to be absorbed, thereby improving the sound absorption performance of the decorative board.

[0038] It should be noted that when assembling the decorative panels, sound-absorbing cotton needs to be filled into the several equilateral triangular spaces formed by the sound insulation folding plate 6, the decorative plate 1, and the base plate 4.

[0039] To further explain, in the equilateral triangle structure formed by the sound insulation folding plates 6, this angle has good stability and helps to disperse external forces. In this way, the sound insulation folding plates 6 are not easily deformed during installation and use, which can ensure the stability of the overall structure.

[0040] The upper and lower ends of the soundproof folding plate 6 are fixedly connected to the mounting plate 7. The mounting plate 7 has positioning holes 8, which correspond to the slots 5. When assembling the decorative panels, the base plate 4 is laid flat first, and then the soundproof folding plate 6 is placed on the base plate 4, with the positioning holes 8 on the mounting plate 7 corresponding to the slots 5. Then, the decorative panel 1 is placed on the soundproof folding plate 6. At this time, the insertion rod 2 will pass through the positioning hole 8 and be inserted into the interior of the slot 5. When the insertion rod 2 is inserted tightly, the positioning ring 3 will press the mounting plate 7 of the soundproof folding plate 6 to improve the stability of the soundproof folding plate 6 and prevent the soundproof folding plate 6 from loosening and affecting the soundproofing effect.

[0041] The soundproof folding plate 6, the decorative plate 1, and the base plate 4 form several equilateral triangles.

[0042] A rod 2 is fixedly connected to one side of the decorative panel 1, and a positioning ring 3 is fixedly connected to the outside of the rod 2.

[0043] The outside of the insertion rod 2 is inserted into the positioning hole 8 and the inside of the slot 5. The positioning ring 3 is set on one side of the mounting plate 7 and presses the mounting plate 7 tightly.

[0044] When using this utility model:

[0045] In the first embodiment, the front sound insulation panel 15 and the rear sound insulation panel 16 are connected together by adhesive. The front sound insulation panel 15 and the rear sound insulation panel 16 form a cavity with the cavity 17. Due to the irregular shape of the cavity, after the sound waves enter the interior of the sound insulation panel, they will undergo extremely complex reflection and scattering in these cavities with different shapes. Compared with regular cavities, irregular cavities make the propagation path of sound waves disordered and unpredictable. This greatly increases the contact opportunities between sound waves and the cavity walls and internal sound-absorbing materials, so that the sound wave energy can be consumed more fully, thereby significantly improving the sound insulation panel's sound blocking and absorption effect.

[0046] In Example 2, the front sound insulation layer 9, the middle sound insulation layer 11, and the rear sound insulation layer 13 are installed by adhesive bonding. From the outer layer to the inner layer of the sound insulation board, the size of the holes gradually decreases, allowing the sound insulation board to selectively absorb sound waves of different frequencies. The large holes 10 first absorb and scatter low-frequency sound waves, the medium holes 12 further absorb mid-frequency sound waves, and the small holes 14 are mainly responsible for absorbing high-frequency sound waves, thereby broadening the sound absorption frequency band and improving the absorption effect of different frequency bands of sound. Furthermore, the decreasing hole structure allows sound waves to undergo multiple reflections, refractions, and absorptions within the sound insulation board. When sound waves enter the sound insulation board from the outer layer, they encounter holes of different diameters, which continuously change their propagation direction and speed, and the energy is gradually consumed. Moreover, this structure can effectively prevent sound waves from directly penetrating the sound insulation board, thereby greatly reducing the propagation of indoor and outdoor sound and improving the noise reduction effect of the decorative board.

[0047] In the third embodiment, when assembling the decorative panel, the operator first lays the base plate 4 flat, then places the sound insulation folding plate 6 on the base plate 4 and aligns the positioning hole 8 on the mounting plate 7 with the slot 5. Then, the decorative panel 1 is placed on the sound insulation folding plate 6. At this time, the insertion rod 2 will pass through the positioning hole 8 and be inserted into the inside of the slot 5. When the insertion rod 2 is inserted tightly, the positioning ring 3 will press the mounting plate 7 of the sound insulation folding plate 6 tightly.

[0048] Secondly, the sound insulation folded plate 6 is made of glass wool. The W-shape allows sound waves to form a more complex reflection and scattering path between the sound insulation folded plates 6. Furthermore, the sound waves are reflected multiple times within the structure of the sound insulation folded plate 6, increasing the contact opportunities with the sound-absorbing material. This more effectively dissipates sound wave energy and improves the sound absorption effect. At the same time, compared to a flat sound insulation board, the sound insulation folded plate 6 forms multiple planes through bending, allowing the same volume of sound insulation board to expose more surface area of ​​sound-absorbing material, enabling more sound waves to be absorbed, thereby improving the sound absorption performance of the decorative board.
