Description

Technical Field

[0001] The present application relates to the technical field of suspended ceilings, and in particular to a suspended ceiling capable of absorbing noise. Background Art

[0002] In the construction industry, suspended ceilings serve as both decorative and functional components within buildings, widely used in various spaces, such as office buildings, shopping malls, theaters, and residences. Existing suspended ceilings primarily serve aesthetic purposes, provide integrated lighting, shield wiring, and provide spatial division. They are typically constructed from gypsum board, metal panels, mineral wool panels, or PVC. While these materials offer some decorative effects and structural support, they have significant limitations in terms of sound absorption and noise reduction.

[0003] Existing suspended ceiling structures often lack specialized acoustically optimized designs, and their surface materials are often rigid or semi-rigid, making them ineffective in absorbing and attenuating sound. Noise within buildings arises from a variety of sources, including conversations, equipment operation, and ambient noise. These noises easily reflect and reverberate within enclosed or semi-enclosed spaces, increasing ambient noise levels and impacting user comfort and productivity. Furthermore, some venues, such as conference rooms, cinemas, and concert halls, demand higher sound quality, but conventional suspended ceilings struggle to meet these acoustic requirements.

[0004] In order to solve the above problems, it is urgent to propose a noise-absorbing ceiling that can effectively absorb and reduce noise propagation, improve the indoor acoustic environment, reduce noise pollution, and improve people's quality of life and work. Summary of the Invention

[0005] The purpose of this application is to overcome the shortcomings of the existing technology and propose a noise-absorbing ceiling that can effectively absorb and reduce noise propagation, improve the indoor acoustic environment, reduce noise pollution, and improve people's quality of life and work.

[0006] This application is achieved through the following technical solutions:

[0007] The present application proposes a suspended ceiling capable of absorbing noise, comprising a suspended ceiling frame fixed to the top, and characterized in that it also comprises a sound absorbing component, wherein the sound absorbing component comprises:

[0008] a first sound-absorbing panel, disposed on a side of the ceiling frame facing away from the top, the first sound-absorbing panel being provided with a plurality of first sound-absorbing holes;

[0009] The second sound-absorbing plate is provided with a plurality of second sound-absorbing holes;

[0010] The annular spacer has one side attached to the first sound absorbing board and the other side attached to the second sound absorbing board, thereby forming a first sound absorbing cavity, and the first sound absorbing cavity is respectively connected to each of the second sound absorbing holes and each of the first sound absorbing holes.

[0011] In one embodiment of the present application, the annular spacer is provided with an open groove toward the top, one side of the open groove is the first sound absorbing panel, and the other side of the open groove is the second sound absorbing panel, thereby forming a first sound absorbing cavity;

[0012] The opening groove is respectively connected to each of the second sound absorbing holes and each of the first sound absorbing holes.

[0013] In one embodiment of the present application, the second sound absorbing plate is provided with a positioning protrusion, and the shape of the positioning protrusion is the same as that of the annular spacer, so that the positioning protrusion and the annular spacer are in abutment with each other.

[0014] In one embodiment of the present application, the second sound-absorbing hole is a cylindrical hole.

[0015] In one embodiment of the present application, the first sound-absorbing hole is a speaker hole, and the aperture of the speaker hole gradually decreases toward the top.

[0016] In one embodiment of the present application, a second sound absorbing cavity is formed between the first sound absorbing panel and the top.

[0017] In one embodiment of the present application, the fastener passes through the second sound absorbing panel and the annular spacer in sequence and is fixedly connected to the first sound absorbing panel.

[0018] In one embodiment of the present application, there are multiple opening slots.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The sound-absorbing assembly comprises a first sound-absorbing panel, a second sound-absorbing panel, and an annular spacer. The first sound-absorbing panel is positioned on the side of the ceiling frame facing away from the top. The first sound-absorbing panel is provided with multiple first sound-absorbing holes; the second sound-absorbing panel is provided with multiple second sound-absorbing holes. The annular spacer is bonded to the first sound-absorbing panel on one side and to the second sound-absorbing panel on the other side, forming a first sound-absorbing cavity. The first sound-absorbing cavity is connected to each second sound-absorbing hole and each first sound-absorbing hole. When noise is generated indoors, sound waves enter the ceiling system from below. They first pass through the second sound-absorbing holes in the second sound-absorbing panel and enter the first sound-absorbing cavity. Within the first sound-absorbing cavity, the sound waves are reflected and absorbed multiple times, dissipating some of their energy and reducing their energy. After repeated reflections and energy dissipation, they re-enter the first sound-absorbing holes. The design of the first sound-absorbing cavity ensures sufficient noise absorption, particularly effectively reducing both low- and high-frequency noise, making it suitable for environments with high noise control requirements. It can also significantly reduce the noise level in the space, avoid echo and reverberation, and improve the clarity and comfort of sound. It is particularly suitable for conference rooms, cinemas, concert halls and other places.

[0035] Please refer to Figures 1 to 4 The present application provides a ceiling 10 that can absorb noise, comprising a ceiling framework 100 fixed to the top and a sound absorption assembly 200, the sound absorption assembly 200 comprising a first sound absorption plate 210, a second sound absorption plate 230 and a ring-shaped hollow frame 220, the first sound absorption plate 210 being arranged on the side of the ceiling framework 100 away from the top, the first sound absorption plate 210 being provided with a plurality of first sound absorption holes 211; the second sound absorption plate 230 being provided with a plurality of second sound absorption holes 231; the ring-shaped hollow frame 220 being attached to the first sound absorption plate 210 on one side and to the second sound absorption plate 230 on the other side, thereby forming a first sound absorption cavity 250, the first sound absorption cavity 250 being in communication with each second sound absorption hole 231 and each first sound absorption hole 211 respectively.

[0036] Specifically, the first sound absorption plate 210 is arranged on the side of the ceiling framework 100 away from the top, facing the indoor space, and the surface is uniformly distributed with a plurality of first sound absorption holes 211. The second sound absorption plate 230 is provided with a plurality of second sound absorption holes 231, which further guide the absorbed sound waves into the upper layer of the first sound absorption cavity 250, reducing the loss of sound wave reflection and improving the sound absorption effect. The ring-shaped hollow frame 220 is located between the first sound absorption plate 210 and the second sound absorption plate 230, and its two sides are attached to the two sound absorption plates respectively, forming the first sound absorption cavity 250. The first sound absorption cavity 250 provides sufficient sound absorption space, and the ring-shaped hollow frame 220 is in communication with the first sound absorption hole 211 and the second sound absorption hole 231 respectively, so that the sound waves passing through the second sound absorption hole 231 can enter the first sound absorption cavity 250 and be reflected and attenuated in the first sound absorption cavity 250, reducing the sound energy. The sound waves enter the first sound absorption cavity 250 through the second sound absorption hole 231 and further eliminate noise by entering the first sound absorption hole 211 upward.

[0037] When noise is generated indoors, sound waves enter the ceiling system from below. The sound waves first enter the first sound-absorbing cavity 250 through the second sound-absorbing holes 231 in the second sound-absorbing panel 230. Within the first sound-absorbing cavity 250, the sound waves are reflected and absorbed multiple times, partially dissipating their energy and reducing their energy. The design of the first sound-absorbing cavity 250 ensures sufficient noise absorption, particularly effectively reducing both low- and high-frequency noise, making it suitable for environments with demanding noise control requirements. It also significantly reduces noise levels in a space, avoids echoes and reverberations, and improves sound clarity and comfort, making it particularly suitable for venues such as conference rooms, cinemas, and concert halls.

[0038] Please refer to Figure 2 In one embodiment, the annular spacer 220 is provided with an open groove 221 toward the top, with the first sound absorbing panel 210 on one side of the open groove 221 and the second sound absorbing panel 230 on the other side, thereby forming a first sound absorbing cavity 250; the open groove 221 is respectively connected to each second sound absorbing hole 231 and each first sound absorbing hole 211.

[0039] Specifically, the annular spacer 220 has an open slot 221 extending through it toward the top. One side of the slot 221 mates with the first sound-absorbing panel 210, and the other side mates with the second sound-absorbing panel 230, thereby forming a first sound-absorbing cavity 250 between the two. A second sound-absorbing cavity 260 is formed between the first sound-absorbing panel 210 and the top. This structural design not only provides sufficient internal space for sound wave reflection and attenuation within the first sound-absorbing cavity 250, but also allows the slot 221 to connect it to the first sound-absorbing hole 211 and the second sound-absorbing hole 231. This allows sound waves, after entering the second sound-absorbing hole 231, to smoothly enter the first sound-absorbing cavity 250 through the slot 221. After repeated reflection and energy dissipation, they then pass through the first sound-absorbing hole 211 and into the second sound-absorbing cavity 260. The presence of the opening groove 221 can enhance the diffusion of sound waves in the sound-absorbing cavity, so that the sound waves are reflected, refracted and absorbed multiple times in multiple paths, thereby improving the loss efficiency of sound energy and significantly enhancing the noise reduction effect.

[0040] Please refer to Figure 2 In one embodiment, the second sound absorbing plate 230 is provided with a positioning protrusion 232 , and the shape of the positioning protrusion 232 is the same as that of the annular spacer 220 , so that the positioning protrusion 232 and the annular spacer 220 can be abutted and fitted.

[0041] Specifically, in order to ensure the precise docking between the second sound absorbing panel 230 and the annular spacer frame 220 and improve the stability and assembly accuracy of the component, a positioning protrusion 232 is provided on the second sound absorbing panel 230. The shape of the positioning protrusion 232 is the same as that of the annular spacer frame 220, so that it can precisely abut and fit with the annular spacer frame 220.

[0042] In one embodiment, the second sound absorbing hole 231 is a cylindrical hole. The first sound absorbing hole 211 is a horn hole, and the aperture of the horn hole gradually decreases toward the top.

[0043] Specifically, the cylindrical second sound-absorbing hole 231 ensures that sound waves propagate in a straight line upon entering the first sound-absorbing cavity 250, reducing diffraction and energy loss upon initial entry, allowing sound waves to more smoothly enter the first sound-absorbing cavity 250 for reflection and absorption. The first sound-absorbing hole 211 has a horn-shaped structure, with the aperture gradually decreasing from bottom to top, with the horn opening facing the top. This structural design, optimized based on the principles of sound wave propagation, gradually focuses sound waves as they pass through the horn opening and upward into the second sound-absorbing cavity 260, enhancing the absorption of sound waves entering the second sound-absorbing cavity 260. Furthermore, the tapered structure of the horn-shaped hole changes the propagation angle of the sound waves, causing them to reflect multiple times within the cavity, improving the efficiency of sound energy attenuation and achieving more efficient sound absorption.

[0044] Please refer to Figures 1 to 4 In one embodiment, the fastener 240 passes through the second sound absorbing panel 230 and the annular spacer 220 in sequence and is fixedly connected to the first sound absorbing panel 210 .

[0045] Specifically, fasteners 240 sequentially pass through the second sound-absorbing panel 230 and the annular spacer 220, and are securely connected to the first sound-absorbing panel 210. This creates a stable, integrated structure for the entire sound-absorbing assembly 200, effectively preventing loosening, displacement, or structural deformation caused by gravity, vibration, or long-term use. This ensures the integrity and sealing of the sound-absorbing cavity, preventing sound leakage due to gaps between the panels, which could compromise the sound absorption effect.

[0046] Please refer to Figure 2 In one embodiment, there are multiple opening slots 221 .

[0047] Specifically, multiple openings 221 are provided, thereby forming multiple independent first sound-absorbing cavities. By providing multiple openings 221, sound waves entering the second sound-absorbing holes 231 can follow different paths into the first sound-absorbing cavity, undergoing multiple reflections, refractions, and energy attenuation within the multiple cavities. The design of multiple openings 221 also prevents sound waves from forming standing waves or resonance within the cavity, further enhancing the noise reduction effect.

[0048] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
