Description

Technical Field

[0001] This utility model relates to the field of noise reduction material technology, specifically a vibration damping and sound-absorbing board. Background Technology

[0002] With the continuous increase in industrial production, transportation, and construction activities, noise pollution has become increasingly serious. Prolonged exposure to noisy environments can negatively impact people's physical and mental health, causing conditions such as hearing loss and increased psychological stress. In the construction field, noise-reducing panels are primarily used for wall and ceiling decoration in conference rooms, concert halls, and residences to reduce external noise interference and improve the indoor acoustic environment. In the industrial field, they are mainly installed in factory workshops, machine rooms, and other areas with high equipment noise levels to reduce noise, protect workers' hearing, and meet environmental protection requirements.

[0003] When using sound-absorbing panels, traditional sound-absorbing panels are generally designed for places with high noise levels, such as concert halls. However, because the frequency of sound vibration is too high, they often fail to achieve the desired noise reduction effect, thus reducing the efficiency of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a vibration damping and sound-absorbing plate to solve the problem mentioned in the background art that traditional sound-absorbing plates are generally designed for places with high noise levels, such as concert halls. However, due to the excessive frequency of sound vibration, they often fail to achieve the ideal noise reduction and sound absorption effect, thus reducing the working efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping and sound-absorbing plate, comprising a vibration damping and sound-absorbing plate body, wherein a vibration damping groove is formed on the front outer surface of the vibration damping and sound-absorbing plate body, a first damping rubber pad is adhered to the rear inner surface of the vibration damping groove, a first rubber block is provided near the four corners on the front outer surface of the first damping rubber pad, a first engaging groove is formed on the front outer surface of the four first rubber blocks, a vibration damping spring is engaged and connected inside the four first engaging grooves, a partition is fixedly connected to the inner wall of the vibration damping groove near the center, a second damping rubber pad is adhered to the rear outer surface of the partition, and a second rubber block is provided near the four corners on the rear outer surface of the second damping rubber pad.

[0006] In a preferred embodiment, a second engaging groove is provided on the rear outer surface of each of the four second rubber blocks, and the second engaging groove is engaged and connected to one end of the shock-absorbing spring.

[0007] In a preferred embodiment, a sound-absorbing groove is provided on the front outer surface of the main body of the vibration damping and sound-absorbing plate near the edge of the partition.

[0008] In a preferred embodiment, the inner wall of the sound-absorbing groove is provided with a sponge block.

[0009] In a preferred embodiment, a sound-absorbing plate is fixedly connected to the inner wall of the silencing groove near the front edge.

[0010] In a preferred embodiment, the sound-absorbing panel has a sound-collecting groove inside.

[0011] In a preferred embodiment, sound-absorbing panels have sound-permeable holes on both the front and rear outer surfaces.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the noise generated indoors is first conducted through the sound-permeable holes on the sound-absorbing panel to the inside of the sound-receiving groove. Utilizing the principle of "thin-plate resonance sound absorption," the thin plate absorbs a large amount of sound energy at the resonant frequency due to its violent vibration. The absorbed sound energy is then conducted through the inner sound-permeable holes to the inside of the sound-absorbing groove, where it is reduced and silenced by sponge blocks, thus improving the equipment's performance. When the sound energy frequency is too high, the first and second damping rubber pads provide initial shock absorption. The first and second rubber blocks further buffer the sound, achieving secondary shock absorption. Finally, the damping springs provide additional buffering, further improving the equipment's efficiency and significantly reducing noise. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a vibration damping and sound-absorbing plate, including a vibration damping and sound-absorbing plate body 1. A vibration damping groove 2 is formed on the front outer surface of the vibration damping and sound-absorbing plate body 1. Vibration damping components such as a first damping rubber pad 3 can be installed through the vibration damping groove 2. A first damping rubber pad 3 is adhered to the rear inner surface of the vibration damping groove 2. A first rubber block 4 is provided near each of the four corners on the front outer surface of the first damping rubber pad 3. A first engaging groove 5 is formed on the front outer surface of each of the four first engaging grooves 5. A vibration damping spring 6 is engaged and connected inside each of the four first engaging grooves 5. A partition 7 is fixedly connected near the center of the inner wall of the vibration damping groove 2. A second damping rubber pad 8 is adhered to the rear outer surface of the partition 7. Under the high elasticity of the first damping rubber pad 3 and the second damping rubber pad 8, they can deform when subjected to force, playing a role in buffering and shock absorption. Furthermore, under the damping performance, they can effectively absorb vibration energy and reduce the transmission of vibration and noise. The rear outer surface of the second damping rubber pad 8 is provided with a second rubber block 9 near the four corners. Under the action of the first rubber block 4 and the second rubber block 9, the vibration generated by noise is buffered a second time. The rear outer surface of the four second rubber blocks 9 is provided with a second engaging groove 10, and the second engaging groove 10 is engaged and connected to one end of the shock-absorbing spring 6. The two ends of the shock-absorbing spring 6 can be engaged and fixed through the first engaging groove 5 and the second engaging groove 10.

[0022] A sound-absorbing groove 11 is provided on the front outer surface of the main body 1 near the edge of the partition 7. The sound-absorbing groove 11 can seal off the noise. At the same time, a sponge block 12 is filled in. The inner wall of the sound-absorbing groove 11 is provided with a sponge block 12. The sponge block 12 can gradually reduce the transmitted noise and achieve the noise reduction effect.

[0023] A sound-absorbing plate 13 is fixedly connected to the inner wall of the sound-absorbing groove 11 near the front edge. The sound-absorbing plate 13 has a sound-collecting groove 14 inside. The outer surfaces of the front and rear sides of the sound-absorbing plate 13 are provided with sound-permeable holes 15. Through the principle of "thin plate resonance sound absorption" of the sound-absorbing plate 13, the sound is conducted to the inside of the sound-collecting groove 14 through the sound-permeable holes 15, and then conducted to the sponge block 12 inside the sound-absorbing groove 11 for noise reduction.

[0024] Working principle: When the vibration damping and sound absorption plate reduces noise in the room, the noise generated in the room is first conducted to the inside of the sound receiving groove 14 through the sound transmission holes 15 on the sound absorption plate 13. Through the principle of "thin plate resonance sound absorption", at the resonance frequency, the thin plate absorbs a large amount of sound energy due to violent vibration. Then, the absorbed sound energy is conducted to the inside of the sound absorption groove 11 through the sound transmission holes 15, where it is reduced and silenced by the sponge block 12, thus improving the performance of the equipment. When the sound energy frequency is too high, the first damping rubber pad 3 and the second damping rubber pad 8 play a preliminary damping role. The first rubber block 4 and the second rubber block 9 buffer the secondary damping role. Finally, the damping spring 6 provides a buffering effect again, further improving the working efficiency of the equipment and greatly reducing noise.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
