Description

Technical Field

[0001] This utility model relates to the field of concrete panel technology, and in particular to a bamboo-textured fair-faced concrete acoustic panel. Background Technology

[0002] In the field of modern architecture, as people's requirements for indoor environmental quality continue to rise, the acoustic performance of architectural spaces is receiving increasing attention. Whether in offices, cultural venues, or residential spaces, a good acoustic environment is a crucial foundation for ensuring comfortable work, study, and life. However, traditional building decoration materials have many shortcomings in acoustic treatment, making it difficult to meet the growing demands. Currently, common building wall decoration materials, such as ordinary ceramic tiles and wood panels, have poor sound absorption and insulation properties. Ordinary ceramic tiles have smooth surfaces, making it easy for sound waves to be reflected mirror-like, resulting in noticeable echoes and noise indoors. While wood panels have some sound absorption effect, their sound absorption capacity in the mid-to-high frequency range is limited, and their sound insulation performance is poor, failing to effectively block external noise from entering the room. In places with high acoustic requirements, such as concert halls and conference rooms, using these traditional materials will seriously affect the clarity and quality of sound, interfering with normal communication and activities.

[0003] The inventors believe that the following defects often exist: when sound propagates indoors, due to the lack of effective energy conversion and propagation obstruction, the sound is continuously reflected, forming a strong echo, causing indoor noise superposition and a noisy acoustic environment, which seriously affects people's normal communication, study and rest, and may even cause hearing damage; therefore, in order to address the above problems, a bamboo-textured fair-faced concrete acoustic panel is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as continuous sound reflection forming strong echoes, causing indoor noise accumulation and a noisy acoustic environment, which seriously affects people's normal communication, study and rest, and may even cause hearing damage. Therefore, a bamboo-textured fair-faced concrete acoustic panel is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bamboo-textured fair-faced concrete acoustic panel, comprising a panel body, wherein a plurality of sound-absorbing holes are formed on the surface of the panel body, a concrete frame is fixedly connected to one side of the panel body, a sound insulation board is fixedly connected to the inner surface of the concrete frame, a concrete frame is fixedly connected to one side of the concrete frame, a vibration hole is formed on the surface of the concrete frame, a plurality of springs are fixedly connected to the surface of the vibration hole of the concrete frame, and a vibration plate is fixedly connected to one end of the plurality of springs.

[0006] The aforementioned components achieve the following effects: effectively hindering sound propagation, reducing sound transmission, and disrupting the sound propagation path. This prevents sound from being reflected continuously and forming strong echoes when propagating indoors due to a lack of effective energy conversion and propagation obstruction, which would cause indoor noise accumulation, a noisy acoustic environment, seriously affect people's normal communication, study, and rest, and may even cause hearing damage. This improves the practicality of the device.

[0007] Preferably, a damping layer is fixedly connected inside the mounting plate body, and the damping layer is made of rubber.

[0008] The effect achieved by the above components is that the damping layer, due to the viscoelastic properties of the rubber material itself, hinders the vibration of the mounting plate body, converts the vibration energy into heat energy and consumes it, reduces the secondary sound radiation caused by vibration, and thus reduces noise and echo.

[0009] Preferably, a plurality of bamboo-patterned panels are fixedly connected to the surface of the panel body, and the plurality of bamboo-patterned panels are evenly distributed in a linear array on the surface of the panel body.

[0010] The effect achieved by the above components is that when sound waves encounter the uneven bamboo texture board, they will change their propagation direction and reflect in different directions, thereby avoiding the formation of obvious echoes due to concentrated reflection of sound waves. At the same time, this scattering effect also increases the propagation path of sound waves in the indoor space, giving sound waves more opportunities to be absorbed by other sound-absorbing materials, further reducing noise.

[0011] Preferably, the surface of the bamboo grain board is provided with a barrier layer, and the material of the bamboo grain board barrier layer is a polymer sound insulation film.

[0012] The effect achieved by the above components is that the barrier layer of the bamboo-patterned board can effectively block sound waves from directly penetrating the board body, reduce the amount of sound transmission, reflect the sound waves back into the room, and give the sound more opportunities to be absorbed.

[0013] Preferably, a plurality of reflectors are fixedly connected to one side of the sound insulation panel, and the plurality of reflectors of different lengths are evenly distributed in a circular array on the surface of the sound insulation panel.

[0014] The effect achieved by the above components is that sound is constantly reflected and refracted on the reflector, and each reflection and refraction causes the energy of the sound wave to be gradually lost.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] This invention effectively hinders sound propagation, reduces sound transmission, and disrupts the sound propagation path. It avoids the situation where sound, due to a lack of effective energy conversion and propagation obstruction, causes continuous sound reflection and forms a strong echo when propagating indoors, resulting in superimposed indoor noise and a noisy acoustic environment. This seriously affects people's normal communication, study, and rest, and may even cause hearing damage, thus improving the practicality of the device. Attached Figure Description

[0023] Reference Figure 1-5As shown, this utility model provides a technical solution: a bamboo-textured fair-faced concrete acoustic panel, including a panel body 1, with a plurality of sound-absorbing holes 2 on the surface of the panel body 1, a concrete frame 6 fixedly connected to one side of the panel body 1, a sound insulation board 7 fixedly connected to the inner surface of the concrete frame 6, a concrete frame 3 fixedly connected to one side of the concrete frame 6, vibration holes on the surface of the concrete frame 3, and a plurality of springs 4 fixedly connected to the surface of the vibration holes of the concrete frame 3, with a vibrating plate 5 fixedly connected to one end of each spring 4. When sound is transmitted to the surface of the panel body 1, the sound enters the sound-absorbing holes 2, causing the sound to vibrate, thus vibrating the vibrating plate 5. When spring 4 vibrates under force, this vibration converts sound energy into heat energy through the damping effect of spring 4. Simultaneously, an air barrier is created between the vibrating plate 5 and the sound insulation plate 7, effectively hindering sound propagation, reducing sound transmission, and disrupting the sound propagation path. This prevents sound from continuously reflecting and forming strong echoes due to the lack of effective energy conversion and propagation obstruction when propagating indoors, thus avoiding indoor noise accumulation and a noisy acoustic environment that seriously affects people's normal communication, study, and rest, and may even cause hearing damage. This improves the practicality of the device. A damping layer 8, made of rubber, is fixedly connected inside the mounting plate body 1. When sound waves act on the panel body 1, causing it to vibrate, the damping layer 8, due to the viscoelastic properties of the rubber material, hinders the vibration of the panel body 1, converting the vibration energy into heat energy and dissipating it, thus reducing secondary sound radiation caused by vibration and reducing noise and echo. Several bamboo-patterned panels 9 are fixedly connected to the surface of the panel body 1, and these panels are evenly distributed in a linear array on the surface of the panel body 1. When sound waves encounter the uneven bamboo-patterned panels 9, they change their propagation direction and reflect in different directions, thus avoiding concentrated reflection of sound waves and the formation of obvious echoes. At the same time, this scattering effect also increases the propagation path of sound waves in the indoor space. This allows sound waves to have more opportunities to be absorbed by other sound-absorbing materials, further reducing noise. The surface of the bamboo-patterned board 9 is provided with a barrier layer. The barrier layer of the bamboo-patterned board 9 is made of a high-polymer sound insulation film. The barrier layer of the bamboo-patterned board 9 can effectively block sound waves from directly penetrating the main body of the hanging board 1, reducing the amount of sound transmission and reflecting the sound waves back into the room, so that the sound has more opportunities to be absorbed. Several reflector plates 10 are fixedly connected to one side of the sound insulation board 7. The several reflector plates 10 are of different lengths and are evenly distributed in a circular array on the surface of the sound insulation board 7. When the sound passes through the sound absorption hole 2, the sound is continuously reflected and refracted on the reflector plates 10. Each reflection and refraction will cause the energy of the sound wave to be gradually lost.

[0024] Working principle: When sound travels to the surface of the mounting plate 1, some of the sound enters the sound-absorbing holes 2, causing vibration, which in turn causes the vibrating plate 5 to vibrate. The spring 4 vibrates accordingly, and the damping effect of the spring 4 converts the sound energy into heat energy. At the same time, an air barrier is formed between the vibrating plate 5 and the sound insulation plate 7, effectively hindering sound propagation, reducing sound transmission, and disrupting the sound propagation path. Inside the mounting plate 1, the damping layer 8, due to the viscoelastic properties of the rubber material, hinders the vibration of the mounting plate 1 when it is subjected to sound waves and converts the vibration energy into heat energy, reducing secondary sound radiation. The bamboo-patterned panels 9 on the surface of the mounting plate 1 are distributed in a linear array. The uneven surface causes sound waves to change their propagation direction and reflect in different directions, avoiding concentrated reflections that form obvious echoes. It also increases the propagation path of sound waves, giving them more opportunities to be absorbed by other sound-absorbing materials. The polymer sound insulation film barrier layer on the surface of the bamboo grain board 9 can block sound waves from directly penetrating the board body 1, reducing the amount of transmission and reflecting the sound waves back into the room. In addition, when the sound passes through the sound absorption hole 2, it will be continuously reflected and refracted on the reflective plates 10 of different lengths and arranged in a circular array on one side of the sound insulation board 7, so that the sound wave energy is gradually dissipated. Through the coordinated work of the above parts, the board effectively reduces indoor noise, reduces echoes, and improves the acoustic environment.
