[0001] The utility model belongs to the technical field of sound insulation boards, in particular to a soundproof wallboard suitable for being installed on walls of various specifications. Background Art

[0002] Decorative panels made of polymer materials are becoming increasingly popular across industries due to their versatility, durability, and aesthetics. These panels are widely used in interior design, architecture, and construction, making a significant contribution to the visual appeal and functionality of residential, commercial, and industrial spaces. Despite their many advantages, the acoustic performance of such products needs to be improved by introducing a quieting layer or modifying the backing layer. In addition, such products are usually hard, which makes them difficult to install on curved wall surfaces. These surfaces, such as columns or cylindrical architectural columns, have unpredictable variations in sound reflection, diffusion, and absorption, which affect the quietness of the room. In addition, curved walls can inadvertently focus sound on a specific point or area in the room, resulting in increased sound intensity in the localized focus area or uneven sound distribution. This affects the overall sound quality and listening experience. Utility Model Content

[0019] The flexible acoustic wave impedance layer 13 is used to enhance the sound absorption effect of the installation body 11. The flexible acoustic wave impedance layer 13 can also be deformed synchronously with the installation body 11. The flexible acoustic wave impedance layer 13 is a flexible acoustic material used to adjust the propagation characteristics of sound waves to achieve the effect of improving sound insulation. The flexible acoustic wave impedance layer 13 is a prior art and will not be described in detail here.

[0020] Each of the decorative strips 20 includes a core layer 21, at least one decorative layer 22 disposed on the side wall of one side of the core layer, and a back film 23 disposed on the decorative layer 22 facing the core layer 21. When a plurality of the decorative strips 20 are installed on the flexible sound insulation layer 10, each of the decorative strips 20 has a different thickness, and the gaps between the decorative strips 20 are different. The decorative strips 20 of different thicknesses have different absorption and reflection characteristics for sound, which helps to optimize the acoustic effect and can specifically improve the diffusion of sound waves of a certain frequency.

[0021] Each core layer 21 includes a noise reduction structure layer 211, at least one waterproof layer 212 disposed on the noise reduction structure layer 211, and a connection layer 213 disposed on the waterproof layer 212. The thickness of the core layer 21 is between 1 and 12 mm. In this embodiment, the thickness of each core layer 21 is between 4 and 10 mm to ensure the balance between the weight and strength of the core layer 21, as well as the sound insulation performance.

[0022] The noise reduction structural layer 211 is composed of an antibacterial agent, a flame retardant material, a thermoplastic material, and a cork material, wherein the antibacterial agent can inhibit or kill bacteria, molds and other microorganisms, the flame retardant material improves its fire resistance and slows down the spread of flames, the thermoplastic material can soften and reshape when heated, and harden again after cooling, and the cork material is a sustainable and environmentally friendly material, which realizes the sound insulation of the noise reduction structural layer.
