Description

Technical Field

[0001] The utility model relates to the technical field of sound-absorbing panels, in particular to a self-adjusting sound-absorbing panel. Background Art

[0002] A sound-absorbing panel is a plate-shaped sound-absorbing decorative material with the function of sound absorption and noise reduction. It is widely used in various places where noise needs to be reduced and the acoustic environment needs to be improved. Its surface is usually porous, rough or has a complex structure. By reasonably selecting and arranging, it can significantly improve the indoor acoustic environment and enhance the listening effect.

[0003] The sound absorption performance of the existing sound-absorbing panels is mainly determined by their materials and structures, such as the density, porosity, thickness of the materials, etc. This makes the sound absorption effect of the sound-absorbing panels relatively fixed and unable to be adjusted in real time according to the actual situation. If the sound absorption effect of the sound-absorbing panel is too strong, it may over-absorb the sound energy, weaken the natural propagation of sound in the room, and affect normal speech communication and listening experience. If the sound absorption effect is insufficient, the sound-absorbing panel cannot effectively capture and reduce the indoor noise, resulting in a high noise level. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and propose a self-adjusting sound-absorbing panel.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A self-adjusting sound-absorbing panel, comprising a sound-absorbing panel main body. A group of sound-absorbing holes are arranged on the outer surface wall of the sound-absorbing panel main body. A group of microphones are arranged on one side of the outer wall of the sound-absorbing panel main body. A double-shaft motor is fixedly installed on the top of the sound-absorbing panel main body. Two rotating shafts are fixedly installed at the output end of the double-shaft motor. A first bevel gear is fixedly sleeved on the outer surface wall of each of the two rotating shafts. A housing is fixedly installed on the top of the sound-absorbing panel main body. Two first moving holes are arranged on the outer surface wall of the housing, and the inner surface walls of the two first moving holes are movably inserted with the outer surface walls of the rotating shafts. Two groups of second moving holes are arranged on the top of the sound-absorbing panel main body. A lead screw is movably inserted between the inner surface walls of the two groups of second moving holes. A second bevel gear is fixedly sleeved on the outer surface wall of each of the two lead screws, and the outer surface walls of the two second bevel gears are meshed with the inner surface wall of the first bevel gear. Two sliding grooves are arranged on the inner surface wall of the sound-absorbing panel main body.

[0007] Preferably, a group of sliders are threadedly connected to the outer surface walls of the two lead screws, and the inner surface walls of the two sliding grooves are movably embedded with the outer surface walls of the group of sliders. A group of first baffles are fixedly installed between the outer surface walls of the two groups of sliders.

[0008] Preferably, a group of brackets are fixedly installed on one side of the outer wall of the sound-absorbing panel main body, and a group of compression springs are fixedly installed on one side of the outer wall of the group of brackets.

[0009] Preferably, a storage box is fixedly installed between the outer surfaces of the group of compression springs, and a fireproof board is fixedly installed on one side of the outer wall of the storage box.

[0010] Preferably, a group of air outlet holes are formed on one side of the outer wall of the storage box, and a group of hot melt adhesive columns are arranged on one side of the outer wall of the group of brackets.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] The present utility model can real-time monitor the noise level through a miniature microphone, and when the detected noise is too low, the biaxial motor is started. The biaxial motor drives the screw rod to rotate through the rotating shaft and two bevel gears, so that the slider and the baffle can block part of the sound absorption holes, reducing the sound absorption effect of the sound-absorbing panel. The sound-absorbing panel can adjust the opening and closing state of the sound absorption holes, thereby adjusting the sound absorption effect, which can not only effectively reduce noise interference, but also avoid the influence of excessive sound absorption on normal voice communication, improving the flexibility and comfort of use. The negative oxygen ion layer of the sound-absorbing panel can continuously release negative oxygen ions into the indoor air, playing a role in purifying the air and promoting human health;

[0015] In case of a fire, the hot melt adhesive columns in the present utility model will melt or break, thereby triggering the emergency mechanism of the fireproof board and carbon dioxide gas. The fireproof board quickly seals the holes, slows down the spread of the fire, and at the same time provides heat insulation protection. The release of carbon dioxide gas realizes rapid fire extinguishing by isolating oxygen, improving the fire safety of the sound-absorbing panel. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figures 1-5As shown in the figure, the utility model provides a self-adjusting sound-absorbing panel, which includes a sound-absorbing panel main body 1. A group of sound-absorbing holes 2 are opened on the outer surface wall of the sound-absorbing panel main body 1. A group of miniature microphones 3 are arranged on one side of the outer wall of the sound-absorbing panel main body 1. A double-shaft motor 4 is fixedly installed on the top of the sound-absorbing panel main body 1. The output ends of the double-shaft motor 4 are fixedly installed with two rotating shafts 5. Conical gears one 6 are fixedly sleeved on the outer surface walls of the two rotating shafts 5. A housing 7 is fixedly installed on the top of the sound-absorbing panel main body 1. Two moving holes one 8 are opened on the outer surface wall of the housing 7, and the inner surface walls of the two moving holes one 8 are movably inserted with the outer surface walls of the rotating shafts 5. Two groups of moving holes two 9 are opened on the top of the sound-absorbing panel main body 1. Lead screws 10 are movably inserted between the inner surface walls of the two groups of moving holes two 9. Conical gears two 11 are fixedly sleeved on the outer surface walls of the two lead screws 10, and the outer surface walls of the two conical gears two 11 are meshed and connected with the inner surface walls of the conical gears one 6. Two chutes 12 are opened on the inner surface wall of the sound-absorbing panel main body 1. A group of sliders 13 are threadedly connected to the outer surface walls of the two lead screws 10, and the inner surface walls of the two chutes 12 are movably embedded with the outer surface walls of the group of sliders 13. A group of baffle plates one 14 are fixedly installed between the outer surface walls of the two groups of sliders 13.

[0026] The effect achieved by the entire Embodiment 1 is that the core structure of the sound-absorbing panel main body 1 is divided into two major layers, namely, the sound-absorbing layer and the negative oxygen ion layer. The sound-absorbing layer can effectively absorb noise and reduce the spread of noise. The negative oxygen ion layer can adsorb and decompose harmful substances such as dust, bacteria, and viruses in the air, thereby providing a fresher and healthier indoor environment for the occupants. It can also activate the oxygen molecules in the air, improve the blood oxygen content and cell metabolism ability of the human body, and promote human health. When the sound-absorbing panel main body 1 is working, a group of microphones 3 will monitor the external noise situation in real time. When the noise is too strong, the biaxial motor 4 is in the off state, and the noise will enter a group of sound-absorbing holes 2 inside, causing air flow and friction inside it, reducing the propagation of sound waves, and thus reducing the interference of noise on people. The sound-absorbing panel main body 1 is internally provided with a micro processing controller, and the biaxial motor 4 and the micro processing controller are connected and controlled by wire signals. After a group of microphones 3 detect noise and find that the detected noise exceeds the preset threshold, they will timely send a feedback signal to the above-mentioned micro processing controller. After being processed, analyzed, and judged by the micro processing controller, a control signal instruction is sent to the biaxial motor 4, causing the biaxial motor 4 to start. At this time, the biaxial motor 4 will drive the rotating shaft 5 to rotate inside the movable hole one 8, causing the bevel gear one 6 fixedly sleeved on the outer surface wall of the rotating shaft 5 to start rotating. The bevel gear one 6 will drive the bevel gear two 11 to rotate together, and through the bevel gear two 11, the lead screw 10 will rotate on the inner surface wall of the movable hole two 9. The lead screw 10 will drive the slider 13 to move through the surface thread and cooperate with the chute 12, driving the slider 13 and the baffle two 21 to rise together. When the baffle two 21 is at the same horizontal height as some of the sound-absorbing holes 2, it will block the sound-absorbing holes 2. By reducing the number of sound-absorbing holes 2, the sound-absorbing effect of the sound-absorbing panel main body 1 can be effectively reduced, preventing the strong sound-absorbing effect from affecting normal voice communication.

[0027] Embodiment 2, as Figures 2-5 shown, one side of the outer wall of the sound-absorbing panel main body 1 is fixedly installed with a group of brackets 15. One side of the outer wall of a group of brackets 15 is fixedly installed with a group of compression springs 16. A storage box 17 is fixedly installed between the outer surface walls of a group of compression springs 16. One side of the outer wall of the storage box 17 is fixedly installed with a fireproof board 18. A group of air outlet holes 19 are opened on one side of the outer wall of the storage box 17. One side of the outer wall of a group of brackets 15 is provided with a group of hot melt adhesive columns 20. One side of the outer wall of a group of hot melt adhesive columns 20 is provided with a baffle two 21, and one side of the outer wall of a group of compression springs 16 is fixedly connected to one side of the outer wall of a group of baffles two 21. And the inner surface wall of a group of air outlet holes 19 is fixedly inserted into the outer surface wall of a group of baffles two 21. One side of the outer wall of a group of baffles two 21 is fixedly installed with a group of tension springs 22, and the inner side of the inner wall of the storage box 17 is fixedly connected between the outer surface walls of a group of tension springs 22.

[0028] The effect achieved by the entire Embodiment 2 is that when a fire occurs, the hot-melt adhesive column 20 will break or melt due to the increase in temperature. At this time, the compressed compression spring 16 starts to reset, driving the storage box 17 and the fireproof board 18 to move, so that the fireproof board 18 is closely attached to the sound-absorbing board body 1, blocking the holes on the sound-absorbing board body 1. This can not only effectively slow down the spread speed of the fire through these holes, but also effectively isolate the direct burning of the sound-absorbing board by the flame and high temperature. When the hot-melt adhesive column 20 breaks or melts, the stretched tension spring 22 will also reset, driving the baffle two 21 into the storage box 17. At this time, the carbon dioxide gas stored inside the storage box 17 starts to diffuse, and can achieve the effect of quickly extinguishing the fire by isolating oxygen.

[0029] Working principle: When the sound-absorbing board body 1 is operating, the negative oxygen ion layer on the outside can improve the indoor air quality, and play a role in relieving fatigue and strengthening metabolism through negative oxygen ions. Its built-in micro-microphone array 3 continuously monitors the external noise level. Once it detects that the noise intensity exceeds the standard, the two-axis motor 4 will remain silent, allowing the noise to enter the board through the sound-absorbing holes 2. Inside the sound-absorbing holes 2, the air flow and friction effectively attenuate the sound wave propagation, significantly reducing the interference of the noise on the environment. When the micro-microphone 3 monitors that the external noise weakens to an appropriate level, the two-axis motor 4 is immediately started, driving the rotating shaft 5 to rotate in the movable hole one 8, and then driving the bevel gear one 6 to mesh with the bevel gear two 11. This linkage mechanism prompts the lead screw 10 to rotate in the movable hole two 9, and through the thread action, it pushes the slider 13 to rise along the chute 12. As the slider 13 moves, the connected baffle two 21 gradually rises and blocks part of the sound-absorbing holes 2. By reducing the number of effective sound-absorbing holes 2, the sound-absorbing effect of the sound-absorbing board body 1 can be flexibly adjusted, avoiding the interference of too strong sound-absorbing ability on normal voice communication. In case of a fire emergency, as the temperature rises, the hot-melt adhesive column 20 will quickly break or melt, releasing its restraint. At this time, the compressed compression spring 16 quickly resets, pushing the storage box 17 and the built-in fireproof board 18 forward to move, so that the fireproof board 18 is closely attached to the surface of the sound-absorbing board body 1, effectively closing all the holes. This design not only significantly slows down the spread of the fire through the holes, but also provides an additional heat insulation layer to protect the sound-absorbing board body 1 from the direct damage of the flame and high temperature. At the same time, the failure of the hot-melt adhesive column 20 also triggers the reset of the tension spring 22, prompting the baffle two 21 to be pulled into the storage box 17. At this time, the pre-stored carbon dioxide gas in the storage box 17 starts to be released and quickly diffuses into the surrounding space. The carbon dioxide gas isolates oxygen, effectively inhibits the fire, and achieves the purpose of quickly extinguishing the fire, buying precious time for the fire emergency response.
