Description

Technical Field

[0001] This utility model relates to the field of wall covering technology, and in particular to a curved acoustic wall covering. Background Technology

[0002] In the field of architectural acoustics and decorative materials, traditional wall materials have significant shortcomings in sound processing and spatial adaptation. Curved acoustic wall coverings were developed to address these issues. Traditional wall decoration materials, such as ordinary wallpaper and latex paint, have smooth, flat surfaces that easily cause concentrated reflections of sound waves upon contact. In venues with high acoustic requirements, such as conference rooms, theaters, and music classrooms, these concentrated reflections create strong echoes, resulting in muddy sound, reduced speech intelligibility, and severely impacting communication and the audiovisual experience.

[0003] The inventors believe that the following defects often exist: when sound waves encounter a flat adhesive wall panel, the sound waves are concentrated and reflected on the surface of the adhesive wall panel, resulting in mutual interference of indoor sounds and obvious echoes, which in turn reduces speech clarity, aggravates noise pollution, seriously affects people's normal communication, study and rest, and may even cause hearing fatigue; therefore, a curved acoustic wall panel is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as concentrated reflection of surface acoustic waves, which leads to mutual interference of indoor sounds and obvious echoes, resulting in reduced speech clarity and increased noise pollution. A curved acoustic wall covering is proposed to address these issues.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a curved acoustic wall covering, comprising a covering body, two protrusions on the surface of the covering body, a strip plate slidably connected to the surface of the protrusions, a connecting block fixedly connected to the surface of the strip plate, and a velvet cloth fixedly connected to the surfaces of the two connecting blocks, the velvet cloth being adhered to the surface of the covering body, and a plurality of velvet dots fixedly connected to the surface of the velvet cloth, the plurality of velvet dots having different heights.

[0006] The effect achieved by the above components is that when sound waves encounter uneven, fluffy dots, they change their propagation direction and are reflected in different directions, thus avoiding concentrated reflection of sound waves to form obvious echoes. 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 improving the noise reduction effect.

[0007] Preferably, the surface of the patch body is provided with a plurality of sound-absorbing grooves, and the sound-absorbing grooves are provided with a plurality of refractive protrusions.

[0008] The effect achieved by the above components is that most of the sound waves will penetrate deep into the interior of the patch body through the sound-absorbing grooves. In the sound-absorbing grooves, the sound waves will be continuously reflected, refracted, and rubbed. Each such action will cause the energy of the sound waves to be gradually lost and eventually converted into heat energy and absorbed.

[0009] Preferably, a barb is fixedly connected to one side of the strip plate, and the strip plate is made of rubber.

[0010] The effects achieved by the above components are as follows: the barb and the surface of the groove are bonded together, which increases the stability of the strip plate in the groove. At the same time, the rubber material of the strip plate makes it easy for workers to bend the strip plate and remove it from the groove.

[0011] Preferably, the surface of the patch body is provided with a corrosion-resistant layer, and the corrosion-resistant layer is made of polytetrafluoroethylene.

[0012] The effect achieved by the above components is that polytetrafluoroethylene has excellent chemical stability, can resist the erosion of a variety of chemical substances, and is not easily affected by corrosive substances such as acids and alkalis, thereby protecting the wall covering from corrosion and extending its service life.

[0013] Preferably, the surface of the corrosion-resistant layer is provided with a waterproof layer, and the waterproof layer is made of silicone.

[0014] The effect achieved by the above components is that silicone can form a uniform waterproof protective film on the surface of the wall adhesive, while also having good breathability, which can prevent mold growth on the wall due to moisture accumulation.

[0015] Preferably, the surface of the waterproof layer is provided with a wear-resistant layer, and the wear-resistant layer is made of polyurethane.

[0016] The effect achieved by the above components is that polyurethane has good wear resistance and flexibility, and can withstand a certain degree of friction and scratching without being easily damaged.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] In this invention, when sound waves encounter uneven, fluffy dots, they change their propagation direction and are reflected in different directions, thus avoiding concentrated reflections that could create a noticeable echo. This scattering effect also increases the propagation path of sound waves in the indoor space, giving them more opportunities to be absorbed by other sound-absorbing materials, further improving the noise reduction effect.

[0025] Reference Figure 1-4 As shown, this utility model provides a technical solution: a curved acoustic wall covering, including a covering body 1. Two protrusions 3 are formed on the surface of the covering body 1. A strip plate 5 is slidably connected to the surface of the protrusions 3. Connecting blocks 4 are fixedly connected to the surface of the strip plate 5. A velvet cloth 2 is fixedly connected to the surface of the two connecting blocks 4. The velvet cloth 2 is adhered to the surface of the covering body 1. Several pile dots 6 are fixedly connected to the surface of the velvet cloth 2, with different heights. When the worker inserts the strip plate 5 into the protrusions 3, the velvet cloth 2 adheres to the covering body 1. At this time, irregular height differences are formed between the pile dots 6 of different heights on the velvet cloth 2, thereby dispersing and reflecting sound. When sound waves encounter the uneven pile dots 6, they change their propagation direction and reflect in different directions, thus avoiding concentrated reflection of sound waves and the formation of obvious echoes. This scattering effect also increases the propagation path of sound waves in the indoor space, giving sound waves more opportunities to travel. The sound waves are absorbed by other sound-absorbing materials, further improving the noise reduction effect. The surface of the patch body 1 has several sound-absorbing grooves 7, and each groove 7 contains several refractive protrusions. Most sound waves will penetrate deep into the patch body 1 along the sound-absorbing grooves 7. Within the grooves 7, the sound waves are constantly reflected, refracted, and rubbed. Each such action causes the sound wave energy to gradually dissipate, eventually being converted into heat energy and absorbed. A barbed hook 8 is fixedly connected to one side of the strip plate 5. The strip plate 5 is made of rubber, and the barbed hook 8 adheres to the surface of the groove 3, increasing the stability of the strip plate 5 within the groove 3. Simultaneously, the rubber material of the strip plate 5 allows workers to easily bend it and remove it from the groove 3. The surface of the patch body 1 has a corrosion-resistant layer 9 made of polytetrafluoroethylene (PTFE). PTFE has excellent chemical stability and can resist the erosion of various chemicals.

[0026] It is not easily affected by corrosive substances such as acids and alkalis, thus protecting the wall patch body 1 from corrosion and extending its service life. The surface of the corrosion-resistant layer 9 is provided with a waterproof layer 10, which is made of silicone. Silicone can form a uniform waterproof protective film on the surface of the wall patch body 1, and also has good breathability, which can prevent the wall from becoming moldy due to moisture accumulation. The surface of the waterproof layer 10 is provided with a wear-resistant layer 11, which is made of polyurethane. Polyurethane has good wear resistance and flexibility, and can withstand a certain degree of friction and scratching without being easily damaged.

[0027] Working principle: The strip plate 5 is bent and inserted into the groove 3. Then, the velvet cloth 2 is pressed to make the barbed sticker 8 adhere to the surface of the groove 3. At this time, when the sound wave propagates to the surface of the sticker, it will first come into contact with the velvet dots 6 of different heights on the surface of the velvet cloth 2. The irregular height difference formed by these velvet dots 6 causes the sound wave to change its propagation direction and disperse and reflect in different directions, avoiding the formation of obvious echoes by concentrated reflection of the sound wave. It also increases the propagation path of the sound wave in the indoor space, creating more opportunities for it to be absorbed by the sound-absorbing material. Some of the sound waves will travel along the surface of the sticker body 1. The sound-absorbing groove 7 extends deep into the interior. The refractive protrusions within the sound-absorbing groove 7 cause sound waves to continuously reflect, refract, and rub against each other, gradually dissipating energy and converting it into heat energy for absorption, thus achieving efficient noise reduction. In terms of structural design, the strip plate 5 is bonded to the groove 3 of the fabric body 1 via the barbed stickers 8 on its surface, ensuring the stability of the velvet 2 after installation. The rubber strip plate 5 is also easy to bend and disassemble, facilitating later maintenance. At the same time, the corrosion-resistant layer 9 on the surface of the fabric body 1 is made of polytetrafluoroethylene, which can resist the erosion of various chemical substances.

[0028] The silicone material of the waterproof layer 10 can form a waterproof and breathable protective film to prevent mold growth on the wall, while the polyurethane material of the wear-resistant layer 11 can withstand daily friction and scratches. The three work together to extend the service life of the patch and ensure that it can perform its acoustic and protective functions stably for a long time.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
