Description

Technical Field

[0001] This application relates to the field of architectural acoustics and noise control technology, and in particular to a modular sound insulation panel. Background Technology

[0002] Currently, sound insulation technologies in the field of architectural acoustics are mainly divided into two categories: active noise reduction and passive noise reduction. In passive noise reduction technologies, porous sound-absorbing materials (such as glass wool and rock wool) and resonant sound-absorbing structures (such as perforated panels and thin-plate resonators) are the mainstream solutions. Large concert halls and theaters usually adopt customized acoustic designs, which combine materials with different sound absorption coefficients and frequency characteristics to achieve broadband sound absorption.

[0003] Existing sound insulation panel solutions suffer from problems such as heavy materials, complex construction, and high costs, making them difficult to directly apply to residential environments. The outer layer of the sound insulation panel cannot be integrated with the external environment, and the internal sound insulation materials cannot be customized according to the needs of the site. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a modular sound insulation panel that overcomes these limitations. It aims to solve the problems of existing sound insulation panel solutions, such as heavy materials, complex construction, high costs, difficulty in direct application to residential environments, inability of the outer layer of the sound insulation panel to integrate with the external environment, and inability to customize the internal sound insulation materials according to site requirements.

[0005] To achieve the above objectives, this application provides the following technical solution: a modular sound insulation panel, comprising a metal outer frame, an internal sound-absorbing core layer, a surface layer assembly on the front side of the metal outer frame, the sound-absorbing core layer comprising a gradient density foam layer and a Helmholtz resonant cavity array plate, the gradient density foam layer and the Helmholtz resonant cavity array plate being sequentially installed inside the metal outer frame, the surface layer assembly comprising a decorative perforated plate, multiple sets of metal fasteners on the front side of the metal outer frame, multiple sets of magnetic fastening slots on the back side of the decorative perforated plate, the multiple sets of magnetic fastening slots being interlocked with the multiple sets of metal fasteners, and a support assembly on the back side of the metal outer frame.

[0006] By adopting the above technical solution and setting a metal external frame, the outer surface layer of the metal external frame can adapt to the home environment during use. The sound-absorbing core layer inside the metal external frame can effectively eliminate external noise. After passing through the surface layer components, the external noise enters the sound-absorbing core through the internal holes of the decorative perforated panel. High-frequency sound energy is gradually dissipated by the gradient density foam layer, mid-frequency sound waves excite the viscous vibration of the foam material, and low-frequency sound waves are converted into heat energy through the vibration of the air column at the neck of the Helmholtz resonant cavity array plate. In this way, the overall modular design allows users to freely combine panels with different sound-absorbing characteristics according to acoustic needs. The external surface layer components can be quickly disassembled and installed, and the surface layer components can be customized to ensure visual unity with the external home environment.

[0007] As a preferred technical solution of this application, two sets of insertion slots are provided on one side of the outer metal frame, and two sets of insertion components are installed on the other side of the outer metal frame. The positions of the two sets of insertion components are corresponding to the positions of the two sets of insertion slots.

[0008] By adopting the above technical solution and setting the plug-in slot, it is more convenient to make side connections between multiple sets of metal external frames. The plug-in can slide with the plug-in slot, which is more convenient to use and improves the practicality of the device.

[0009] As a preferred technical solution of this application, the top of the metal outer frame is provided with a top bearing groove, and the bottom of the metal outer frame is provided with a bottom connecting plate, wherein the top bearing groove and the bottom connecting plate are the same size.

[0010] By adopting the above technical solution, and by setting the top bearing groove, it can cooperate with the bottom connecting plate to achieve a quick longitudinal connection of the metal external frame. It can also cooperate with the plug-in parts and plug-in grooves to make the overall connection between multiple metal external frames more convenient.

[0011] As a preferred technical solution of this application, the support assembly includes multiple sets of horizontal support rods, and multiple sets of longitudinal support rods are provided between the multiple sets of horizontal support rods. Both ends of the horizontal support rods and the longitudinal support rods are connected to the external threads of the metal outer frame.

[0012] By adopting the above technical solution and setting horizontal support rods, the metal outer frame can be further reinforced during use, while the internal gradient density foam layer can be limited, thus improving stability during use.

[0013] As a preferred technical solution of this application, a fixing component is provided at each of the four corners of the gradient density foam layer. The fixing component includes a fixing block, a clamping plate is provided inside the fixing block, and a threaded shaft is provided inside the clamping plate. The threaded shaft passes through the gradient density foam layer and the fixing block for threaded connection.

[0014] By adopting the above technical solution and setting fixed components, the gradient density foam layer can be further reinforced during use, and the Helmholtz resonant cavity array plate can be further limited, thereby improving the overall stability of use.

[0015] As a preferred technical solution of this application, an inclined reinforcing rod is provided between the multiple sets of horizontal support rods and the multiple sets of longitudinal support rods, and the two ends of the inclined reinforcing rod are threadedly connected to the horizontal support rods and the longitudinal support rods.

[0016] By adopting the above technical solution and setting inclined reinforcing bars, the stability of the connection between the horizontal support bars and the longitudinal support bars can be further ensured during use, thereby improving the overall stability.

[0017] As a preferred technical solution of this application, all four sets of fixing components are fixedly connected to the inner wall of the metal outer frame, and one side of the four sets of fixing components abuts against the Helmholtz resonant cavity array plate.

[0018] By adopting the above technical solution, all four sets of fixing components are fixedly connected to the inner wall of the metal outer frame, which can ensure the fixing effect between the gradient density foam layers and limit the Helmholtz resonant cavity array plate, ensuring the stability between the gradient density foam layer and the Helmholtz resonant cavity array plate, and improving the sound absorption effect.

[0019] The beneficial effects of this application are:

[0020] 1. By setting up a metal outer frame, the outer surface layer of the metal outer frame can adapt to the home environment during use. The sound-absorbing core layer inside the metal outer frame can effectively eliminate external noise. After the external noise passes through the surface layer components, it enters the sound-absorbing core through the internal holes of the decorative perforated panel. High-frequency sound energy is gradually dissipated by the gradient density foam layer, mid-frequency sound waves excite the viscous vibration of the foam material, and low-frequency sound waves are converted into heat energy through the vibration of the air column at the neck of the Helmholtz resonant cavity array plate. In this way, the overall modular design allows users to freely combine panels with different sound-absorbing characteristics according to acoustic needs. The outer surface layer components can be quickly disassembled and installed, and the surface layer components can be customized to ensure visual unity with the external home environment.
