Description

Technical Field

[0001] This utility model relates to the field of honeycomb panel technology, specifically to a honeycomb panel with good sound absorption effect. Background Technology

[0002] A honeycomb panel is a sheet material made by firmly bonding two thinner panels to both sides of a thicker honeycomb core material; it is also known as a honeycomb sandwich structure. In addition, a honeycomb panel can also refer to a panel in which a large number of cutoff waveguides are welded together to form a cutoff waveguide array, creating a large opening area while preventing electromagnetic wave leakage.

[0003] However, existing honeycomb panels do not have the function of effectively absorbing noise during actual use. This allows noise to penetrate the honeycomb panel and enter the interior, which in turn affects the environment of the users and makes it inconvenient for people to use. Therefore, we propose a honeycomb panel with good sound absorption effect. Utility Model Content

[0004] The purpose of this invention is to provide a honeycomb panel with good sound absorption to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a honeycomb panel with good sound absorption effect, comprising an outer layer, the outer layer including a first sound insulation layer, a second sound insulation layer and a third sound insulation layer, the back side of the first sound insulation layer being fixedly connected to the front side of the second sound insulation layer, the back side of the second sound insulation layer being fixedly connected to the front side of the third sound insulation layer, a honeycomb interlayer being fixedly connected to the inner side of the outer layer, and an inner layer being fixedly connected to the back side of the honeycomb interlayer, the inner layer including a first sound absorption layer, a second sound absorption layer and a third sound absorption layer, the back side of the first sound absorption layer being fixedly connected to the front side of the second sound absorption layer, and the back side of the second sound absorption layer being fixedly connected to the front side of the third sound absorption layer.

[0006] Preferably, the first sound-absorbing layer is made of wood-based sound-absorbing board, the second sound-absorbing layer is made of mineral wool-based sound-absorbing board, and the third sound-absorbing layer is made of polyester fiber-based sound-absorbing board.

[0007] Preferably, the first sound insulation layer is made of gypsum sound-absorbing board, the second sound insulation layer is made of foam sound-absorbing board, and the third sound insulation layer is made of soft-pack sound-absorbing board.

[0008] Preferably, the thickness of the first and second sound-absorbing layers is 0.11cm-0.13cm, and the thickness of the third sound-absorbing layer is 0.12cm-0.14cm.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention utilizes a combination of a first sound insulation layer, a second sound insulation layer, and a third sound insulation layer to isolate external noise. When the noise is too loud, it penetrates the first, second, and third sound insulation layers and comes into contact with the honeycomb interlayer, which then isolates the noise again. Furthermore, a first, second, and third sound absorption layer are incorporated to further isolate the noise, thereby improving sound absorption efficiency. Attached Figure Description
