Description
Technical Field
[0001] The present invention relates to the technical field of sound-absorbing structures, in particular to a gradient noise-reducing composite sound-absorbing body. Background Art
[0002] Sound-absorbing panels are used to absorb sound, thereby reducing noise. There are numerous types of sound-absorbing panels, primarily wood, mineral wool, and fabric. Because they are generally thick, sound-absorbing panels offer sound insulation but lack micro-ventilation. In dark environments, for example, sound-absorbing panels require both excellent sound insulation and ventilation. Existing sound-absorbing panels fail to reset themselves after impact, and their internal space is overfilled, resulting in material waste. Summary of the Invention
[0003] To this end, the technical problem to be solved by the present invention is to provide a gradient noise reduction composite sound absorbing body which is distributed in an arc shape through a sound insulation baffle and forms three groups of sound absorbing structures with a reflection channel and a silencer area, which can absorb sound in an orderly manner and finally reach the silencer area for sound absorption.
[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0005] It includes a decorative surface and a bottom surface, a sound insulation baffle is provided on the lower layer of the decorative surface, a plurality of silencing zones are provided between the decorative surface and the bottom surface, the silencing zones include a movable baffle, a fixed baffle and a connecting strip, the movable baffle is hinged on the top of the bottom surface, the edges of the decorative surface and the bottom surface are buckled with an edge packaging surface, a guide strip is provided on one side of the movable baffle, an edge packaging surface is fixedly provided on the edge of the fixed baffle, a support strip is fixedly provided on one side of the edge packaging surface, a through hole is provided above the decorative surface, a connecting strip is provided on the surface of the through hole, and a connecting channel is provided inside the connecting strip.
[0006] The technical solution of the present invention achieves the following beneficial technical effects:
[0007] This solution forms three groups of sound-absorbing structures through the arc-shaped distribution of sound insulation baffles, reflection channels and silencing areas, which can absorb sound in an orderly manner and finally reach the silencing area for sound absorption. The silencing area is in the shape of a tree branch, so that the sound is reflected in a very small space. By moving the decorative surface toward the bottom surface under the condition of wind or external force, the extremely narrow silencing area can be expanded, and the gas can be easily ventilated. The expanded space can also allow moisture to evaporate quickly. At the same time, the rotation of the movable baffle can form a group of reinforcement structures between the decorative surface, the bottom surface and the edge packaging surface, so that it has a certain buffering effect before impact and a certain strength after impact.

DETAILED DESCRIPTION
[0013] As the instruction manual Figure 1 As shown, the framework of this solution consists of three parts. The decorative surface 1 is a long board. The shape will not be described in detail here. It can be rectangular or square. Below the decorative surface 1 are two sound insulation baffles 29. There is a distance between the two sound insulation baffles 29 so that the sound can be offset between them. The diaphragm baffle material is made of sound-absorbing cotton. Below the sound insulation baffle 29 is the bottom surface 2 of this solution. The size of the bottom surface 2 is consistent with the size of the decorative surface 1. In order to ensure that this solution has a certain strength, edge packaging surfaces 6 are provided on the edges of the bottom surface 2 and the decorative surface 1. The decorative surface 1 has four sides, so the specific shape of the edge packaging surface 6 is a rectangular parallelepiped, and the bottom is hollow. It is sleeved on the edge of the decorative surface 1 to form a complete sound insulation board. The movable baffle 3 and the fixed baffle 4 of this solution are both made of sound-absorbing material.
[0014] An interval is sealed below the highest point of the sound insulation baffle 29 and the bottom surface 2, which is the soundproofing zone. Similarly, another interval is formed above the lowest point of the diaphragm baffle and the decorative surface 1. The principle of this interval is basically the same as that of the soundproofing zone. The difference is that there is a connecting strip 5 in the soundproofing zone, and this interval has an auxiliary rod. In fact, the soundproofing zone can be seen. The sound insulation baffle 29 is a skeleton. The outer surface of this skeleton can be wrapped with a layer of sound-absorbing cotton, and the inside is a metal sheet, which can ensure that the diaphragm baffle has a certain strength. Since the decorative surface 1 of this scheme is movable and lacks a certain hard support, the decorative surface 1 can move a short distance toward the bottom surface 2. This scheme uses this short distance to ventilate the soundproofing zone.
[0015] As the instruction manual Figure 2 , the soundproofing zone has three structures, the first is a movable baffle 3, the movable baffle 3 is rotatably set on the bottom surface 2, one side of the movable baffle 3 is a guide strip 7, and the sound entering the soundproofing zone first needs to pass through the diaphragm baffle to achieve multiple reflection weakening, and the No. 1 strip 20 and the No. 2 strip 21 are installed in the middle of the soundproofing baffle 29. There is an elastic rubber band 27 between the No. 1 strip 20 and the No. 2 strip 21 to connect the two together. Under normal circumstances, there is no gap between the No. 1 strip 20 and the No. 2 strip 21. Since an elastic arc piece 23 is supported on one side of the movable baffle 3, the elastic arc piece 23 is a structure that can be squeezed and restored. The functional principle is similar to that of a clip (which can be replaced by a spring), except that one end is fixed together, so the movable baffle 3 can maintain its position. The inner side of the edge packaging surface 6 can be connected to the fixed baffle 4, and both sides of the fixed baffle 4 extend laterally to the edge packaging surface for fixation, so the fixed baffle 4 is stationary, and a structure similar to the guide strip 7 is provided on both sides of the fixed baffle 4. In this way, after the sound enters the silencing area through the reflection channel 22 between block No. 1 and block No. 2, a part of it will cross-collide along the fixed baffle 4 and the movable baffle 3, gradually forming a sound attenuation. This scheme uses three groups of mechanisms to achieve reflection attenuation of sound and achieve the effect of sound absorption. These three groups are the sound insulation baffle 29, the reflection channel 22, the movable baffle 3 and the fixed baffle 4, and the sound insulation baffle 29 can make the sound-absorbing panel composed of this scheme not need to occupy all the space, which can save materials.
[0016] As the instruction manual Figure 3As shown, as the decorative surface 1 of this solution is blown or manually pressed, the decorative surface 1 moves toward the bottom surface 2. Since a through hole 9 is opened on the decorative surface 1, a connecting strip 5 is integrally provided on the through hole 9. The connecting strip 5 passes downward along the fixed baffle 4 and is pressed under the movable baffle 3. As the decorative surface 1 moves downward, the connecting strip 5 also moves downward. The downward movement of the connecting strip 5 forces the movable baffle 3 to rotate. The movable baffle 3 rotates and docks with the support strip 8. The support strip 8 is also extended to both sides and fixed on the edge packaging surface 6. Therefore, the support strip 8 is quite As the movable baffle 3 is also stationary, one end of the movable baffle 3 can be docked with the docking piece 28, and one side of the docking piece 28 blocks the continued rotation of the movable baffle. At this time, the above-mentioned principle is similar to that of the mute zone (that is, with an auxiliary rod). As the auxiliary rod does not move, the movable baffle 3 on the decorative surface 1 (a part of the movable baffle 3 in this solution is also rotatably set on the decorative surface 1) will also rotate toward the direction of the support bar 8. Since the position of the support bar 8 is fixed, the movable baffle 3 and the support bar 8 on the decorative surface 1 and the bottom surface 2 form a complete bar, as shown in the attached manual. Figure 3 As shown in the instruction manual, Figure 3 It only shows one group, but there are actually multiple groups. This can ensure that the solution has a certain strength and a certain buffering capacity, and can provide stable support after reaching a certain buffering capacity.
[0017] The previous paragraph introduced the stability of the support of this solution. This paragraph introduces the core ventilation of this solution. Since the thickness of the sound-absorbing panels is relatively thick, in order to ensure that the sound insulation panels can be used for a longer time in a humid environment, this solution is designed on the support bar 8. A cylindrical hole is opened on the support bar 8, and a docking rod 11 is sealed and slidably set on the hole. A hidden spring 13 is set on the edge support of the docking rod 11, as shown in the attached manual. Figure 4 As shown, the spring is squeezed at this time, so the docking rod 11 will slide along the oblique downward direction without external force. Figure 4 At this time, the gas can reach the lateral channel 12 along the gap 25 and the blocking block 26. The side of the docking rod 11 is in a Y shape, and the two adjacent docking rods 11 of this solution are symmetrically arranged. Therefore, the Y shape can play a guiding role in the process of gas flowing through the sound insulation baffle 29 (the Y shape is a long strip shape. In order to adapt to the long strip shape and push it out stably, it is necessary to set up multiple parallel instructions). Figure 4 The structure of the instruction manual is attached. Figure 4 The structure has a cylindrical shape and a rectangular shape), so that gas can enter the docking rod 11 more easily.
[0018] In the absence of external force, the docking rod 11 extends out of the notch 25 and the blocking block 26 to form a complete circle, and in the case of external force, the docking rod 11 extends out of the notch 25 and the blocking block 26 to form a complete circle. Figure 4As shown in the figure, a dislocation is formed, so that the gas can enter the inside of the side channel 12. This external force is also exerted through the movable baffle 3, as shown in the appendix of the specification. Figure 4 As shown, there is an inclined surface on one side of the movable baffle 3. This inclined surface can contact the edge of the docking rod 11 during the rotation process, so that the edge of the docking rod 11 is squeezed. Therefore, when the movable baffle 3 rotates, it can squeeze the docking rod 11 obliquely upward, so that the docking rod 11 is as shown in the appendix of the manual. Figure 4 As shown, if the movable baffle 3 is away from the support bar 8, the docking rod 11 will be blocked obliquely upward to achieve a sealing effect. Figure 4 At this time, the movable baffle 3 and the support bar 8 will be connected, so that the lateral channel 12 and the docking channel 14 are connected. A sealing gasket is provided on one side of the movable baffle 3 to ensure that the lateral channel 12 and the docking channel 14 are sealed and connected. In this way, the docking channel 14 of this solution will be ventilated. Figure 3 As shown, in order to form a correspondence with the fixed baffle 4, a channel is also provided on the connecting strip 5 of this solution.
[0019] The middle part of the connecting strip 5 is hollow, and the hollow structure is the connecting channel 10. The top of the connecting channel 10 is a plurality of elastic sheets 18. The elastic sheets 18 are formed into four equal circles and have a little elasticity. They can be squeezed and rotated. After squeezing, the top of the sealed connecting channel is reset. The elastic sheets 18 extend toward one side of the through hole 9 on the inner side of the fixed baffle 4, pass upward to the side of the connecting strip to reach the top of the connecting strip 5, and then pass into the interior of the connecting strip 5. The connecting strip 5 is fixedly set on the through hole 9 (it does not completely block the through hole 9). When the decorative surface 1 moves downward, the connecting strip 5 also moves downward. The insertion block 19 and the fixed baffle 4 are stationary. Therefore, the downward movement can rotate the movable baffle 3, and at the same time, the top elastic sheet 18 contacts the insertion block 19, so that the elastic sheet 18 rotates upward. Figure 3 As shown in the enlarged diagram above, the interior of the connecting channel 10 can be ventilated, and the connecting channel 10 has side openings on both sides, as shown in the attached manual. Figure 3 As shown in the flow arrow position, the gas can reach both sides of the fixed baffle 4 and ventilate the structure similar to the guide strip 7 on the fixed baffle 4. When the decorative surface 1 does not move downward, as shown in the attached manual, Figure 2 As shown, at this time, the connecting channel 10 and the structure similar to the guide strip 7 on the fixed baffle 4 are misaligned, so it is equivalent to not being connected, and the gas cannot pass through.
[0020] In order to make the ventilation process able to communicate with the outside, this solution is provided with an exhaust channel 16 on the bottom surface 2. One side of the exhaust channel 16 can be connected to the edge packaging surface 6, and the edge packaging surface 6 can be transported to the top along the side to achieve the effect of communicating with the outside (as shown in the attached manual). Figure 1 As shown, in Figure 1 There is a channel corresponding to the exhaust channel 16 on the edge packaging surface 6), and the connecting channel is provided with an elastic strip 17 at the lower position of the connecting strip 5. The principle of the elastic strip 17 is similar to that of the elastic sheet 18, and ventilation is also achieved by squeezing. A protruding tube 24 is provided below the connecting strip 5. The protruding tube 24 is in the shape of a semicircular tube. After the connecting strip 5 is inserted into the exhaust channel 16, the protruding tube 24 can supply gas to flow into the exhaust channel 16, thereby achieving communication with the outside and completing the cycle of the entire action.
[0021] Finally, the effect of this solution is introduced. This solution can reduce the sound under normal conditions under the combination of three groups of sound reduction. The arc-shaped setting of the sound insulation baffle 29 can make the sound re-reflected inside the sound insulation baffle 29, so as to achieve the effect of reducing the volume. In addition, there is a reflection channel 22 between the No. 1 block and the No. 2 block of this solution, which can transmit the sound to the silencing zone. The silencing zone is in the shape of a tree branch, so that the sound is reflected in an extremely small space. With the use of this solution, since the silencing zone has an extremely small silencing area, in order to ventilate and dehumidify the silencing zone, the decorative surface 1 is moved toward the bottom surface 2 under wind or external force, which can expand the space of the extremely narrow silencing zone, make it easy for gas to enter for ventilation, and the expanded space can also make moisture evaporate quickly. At the same time, the rotation of the movable baffle 3 can form a group of reinforcement structures between the decorative surface, the bottom surface 2 and the edge packaging surface 6, so that it has a certain buffering effect before the impact and a certain strength after the impact.
