Description

Technical Field

[0001] The invention relates to the technical field of noise reduction, in particular to a sound insulation structure and sound insulation glass. Background Art

[0002] With the improvement of economic level and the development of urban construction, the environmental vibration and noise problems induced by urban transportation, construction, industrial production, social life, etc. are becoming more and more serious, and people are paying more and more attention to the comfort of indoor vibration and acoustic environment of buildings. As one of the important interactive media between indoor and outdoor of buildings, building windows have an important impact on the quality of indoor acoustic environment. However, the noise reduction and vibration reduction design of existing building windows still has certain defects, resulting in that the comfort of indoor acoustic environment of buildings cannot be well guaranteed.

[0003] On the one hand, the main body of the glass is the weak part of the window sound insulation. Due to the existence of the acoustic mass law, the sound insulation of the glass increases with the increase of the sound frequency, which means that ordinary windows have poor sound insulation performance for noise in the medium and low frequency areas, especially noise with a frequency below 1000Hz. A large part of the noise generated by outdoor traffic, construction, industrial production and social life is in this frequency band. This part of noise can easily be transmitted into the room through the window glass, which will not only damage the physical and mental health of the people in the room, but also may cause damage to the precision instruments and equipment in the room. Therefore, there is an urgent need for a sound insulation structure that can be applied to the main part of the window glass to solve the problem of insufficient sound insulation performance of low-frequency noise.

[0004] On the other hand, subways, light rails and other trains will transmit vibrations to surrounding buildings or superstructures when they are in operation. Studies have shown that this type of vibration is low-frequency and usually contains high energy, which may cause greater vibrations in buildings, and in turn cause vibrations in building doors and windows. Frequent vibrations will increase fatigue damage to windows, cause damage and fall off of seals, and in turn affect the sealing performance of windows, leading to the penetration of indoor air and external noise. Excessive vibrations may even cause doors and windows to generate secondary noise, greatly affecting the indoor sound environment. In addition, during daily use, building windows will also have certain vibrations transmitted to the window glass structure, which may damage the glass structure and affect the performance of the windows. In order to reduce the negative impact of door and window vibrations, the overall vibration reduction performance of windows needs to be improved. Summary of the invention

[0005] Some simplifications or omissions may be made in this section and the abstract and title of the present application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0006] In view of the above problems or problems existing in the prior art, the present invention is proposed.

[0007] Therefore, the object of the present invention is to provide a sound insulation structure, the prior art of which has poor absorption of sound waves in the mid- and low-frequency bands.

[0014] As a preferred solution of the sound insulation structure of the present invention, a partition is arranged on the first surface of the main body, and the partition at least covers a part of the opening of the cavity, so that the partition forms a through opening at its opening.

[0015] As a preferred solution of the sound insulation structure of the present invention, a plurality of groups of rebound members are arranged inside the chamber.

[0016] As a preferred solution of the sound insulation structure of the present invention, the mass block inside the chamber can be any one or more combinations of a cuboid, a cylinder, a triangular prism, etc.

[0017] Beneficial effects of the present invention: When low-frequency sound waves propagate and impinge on the main body, the rebound member in the chamber will begin to vibrate due to resonance, the force of the sound waves on the main body and the reaction force generated by the vibration of the rebound member will offset each other, and the vibration of the main body will be weakened, thereby achieving the sound insulation effect of low-frequency noise.

[0018] As a preferred solution of the sound insulation structure of the present invention, the sound absorbing component comprises an outer layer of glass and an inner layer of glass respectively arranged on both sides of the sound insulation structure; and

The "vibrator" can also reduce the low frequency vibration of the glass in a relatively small size, reducing the possibility of secondary noise generated by the window due to low frequency vibration. The present invention adds a vibration reduction block in the installation frame to avoid direct connection between the glass body and the installation frame, thereby reducing the impact of vibration on the window structure.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1

[0041] The existing sound insulation structure has poor sound insulation performance for medium and low frequency noise, and many noises in life are medium and low frequency noises.

[0042] In order to solve the above technical problems, the present disclosure proposes a sound insulation structure.

[0043] Reference Figure 1 , which is the first embodiment of the present invention, provides a sound insulation structure, which includes a main body 101, which has a first surface 101a, and the first surface 101a is concave to form a chamber 102; and,

[0044] The rebound member 103 is disposed inside the chamber 102 and is capable of reflecting the sound waves entering the chamber 102 from the first surface 101 a .

[0045] The main body 101 in the present invention is a flat plate structure made of a transparent material, and the material can be preferably made of glass. The first surface 101a is a side surface of the main body 101 for facing the sound waves.

[0046] The first surface 101a has a cavity 102 that is recessed toward the inside of the main body 101 and is connected to the outside. The cavity 102 can be made into a cavity with a gradually increasing cross-sectional area that is recessed inward, such as Figure 1 As shown, when the wave passes through the chamber 102 and the sound wave frequency matches the frequency of the chamber 102, it will cause the air in the chamber 102 to resonate. Under the excitation of the sound wave, the air will rush from the outside of the chamber 102 to the inside of the chamber 102. Since the hole at the entrance of the chamber 102 is smaller than the inside, the hole will produce viscous loss with the air, and the sound wave energy will be converted into heat energy and weakened. After that, the pressure in the chamber 102 increases, and the air in the chamber 102 will flow to the outside of the chamber 102, and part of the sound wave energy will be consumed when passing through the hole. This is repeated, and finally the sound wave energy in the structure is converted into heat energy and the kinetic energy of the air, realizing the absorption of the matching frequency sound wave.

[0047] The rebounding member 103 forms a "cavity-vibrator" structure with the chamber 102. For example, the rebounding member 103 may be a block structure elastically fixed to the bottom or inner wall of the chamber 102, which can elastically vibrate with the impact of sound waves and reflect the sound waves.

[0048] The sound wave passing through the chamber 102 will reach the rebound member 103, driving the rebound member 103 to vibrate together. At this time, the rebound member 103 vibrates back and forth in the wave incident direction. The rebound member 103 will produce resonance, and the sound wave energy will be localized, that is, limited to the inside of the chamber 102, and the back and forth vibration will consume it and cannot continue to propagate.

[0049] In summary, when the sound wave enters the chamber 102 and contacts the rebound member 103 or the main body 101 and continues to propagate, the sound wave energy is constantly confined in each rebound member 103, and the energy is converted back and forth between the kinetic energy of the mass block 103b and the deformation potential energy of the first elastic member 103a. The sound wave energy is finally converted into the kinetic energy and heat energy of the rebound member 103 and is consumed.

[0050] Example 2

[0051] Reference Figure 1-2 , which is the second embodiment of the present invention, is different from the first embodiment in that: the opening of the chamber 102 also includes a through hole 101a - 1, and the cross section of the through hole 101a - 1 is smaller than the cross section of the chamber 102.

[0052] Among them, the chamber 102 is recessed into the main body 101, and the cross-sectional size of the chamber 102 can be the same, but a through hole 101a-1 is opened where the chamber 102 is connected to the outside, and the cross-sectional area of ​​the through hole 101a-1 is smaller than the cross-sectional area of ​​the chamber 102; the advantage of such a design is that the chamber 102 forms a Helmholtz resonator structure, which can cause the air in the cavity to resonate when the sound wave frequency matches the cavity frequency, thereby generating viscous loss between the inner wall of the through hole 101a-1 and the air.

[0053] In the previous embodiment, the rebound member 103 includes a first elastic member 103 a and a mass block 103 b ; the mass block 103 b is fixed to the inner wall of the chamber 102 through the first elastic member 103 a .

[0054] In this solution, the first elastic member 103a can be a compression spring, a gasket of elastic material, etc., and the mass block 103b is a block made of rigid material; the first elastic member 103a is fixed to the inner wall of the chamber 102, and the inner wall includes any side of the interior of the chamber 102. In this solution, the rebound member 103 is fixedly installed on the inner wall of the chamber 102 opposite to the opening 101a-1; when the sound wave is transmitted into the interior of the chamber 102 through the opening 101a-1, the sound wave begins to be reflected by the inner wall of the chamber 102 and the mass block 103b. At the same time, the sound waves reflected by the inner wall of the chamber 102 will be transmitted to the surface of the mass block 103b, thereby driving the mass block 103b to vibrate. At this time, the first elastic member 103a and the mass block 103b in the rebound member 103 will vibrate back and forth in the incident direction, and the rebound member 103 will produce a resonance effect. The sound wave energy is localized and will be converted back and forth between the kinetic energy of the mass block 103 and the deformation potential energy of the first elastic member 103a, and finally converted into the kinetic energy and heat energy of the mass block and consumed, and cannot continue to propagate.

[0055] The rebound member 103 also has good vibration reduction performance for low-frequency vibration. The rebound member 103 can be simplified as a "spring-mass" system. When the vibration propagates to the main body 101 in the form of elastic waves, it will exert a force on the main body 101, and the movement of the mass block 103b will also produce a reaction force on the main body 101. Therefore, the main body 101 moves under the action of the external excitation force and the internal reaction force. When the frequency of the external excitation is close to the natural frequency of the rebound member 103, the rebound member 103 resonates, and the reaction force of the rebound member 103 on the main body 101 is always reversely superimposed with the external excitation force, and the vibration of the main body 101 is weakened. When the frequencies of the two are completely equal, anti-resonance occurs, that is, the resultant force acting on the main body 101 tends to zero, and the vibration is completely offset. Therefore, the vibration cannot propagate in the main body 101, and the energy is absorbed by the rebound member 103 and confined in each chamber 102.

[0056] In summary, the sound wave enters the chamber 102 from the opening 101a-1, hits the surface of the mass block 103b, and squeezes the first elastic member 103a at the same time. At this time, the rebound member 103 begins to consume the energy of the sound wave, and then the sound wave that penetrates the mass block 103b and the sound wave that does not hit the surface of the mass block 103b hits the inner wall of the chamber 102, and then rebounds and hits the surface of the mass block 103b, so that the mass block 103b oscillates back and forth in the vertical direction, consuming the energy of the sound wave; in this process, when the sound wave propagates to the main body 101 in the form of an elastic wave, it will exert a force on the main body 101, and the movement of the mass block 103b also produces a reaction force on the main body 101, so the main body 101 moves under the action of the external excitation force and the internal reaction force. When the frequency of the external excitation is close to the natural frequency of the rebound member 103, the rebound member 103 resonates, and the reaction force of the rebound member 103 on the main body 101 is always reversely superimposed with the external excitation force, and the vibration of the main body 101 is weakened. When the frequencies of the two are completely equal, anti-resonance occurs, that is, the resultant force acting on the main body 101 approaches zero and the vibration is completely offset.

[0057] Example 3

[0058] Reference Figure 1 to Figure 4 , which is the third embodiment of the present invention, is different from the first two embodiments in that it includes at least one chamber 102 and at least one group of rebound members 103 are provided inside the chamber 103.

[0059] In order to absorb sound wave energy in a wide range, a plurality of chambers 102 are arranged on the surface of the main body 101, and a rebound member 103 can be arranged according to the scene noise frequency band used by the sound insulation structure 100 to increase the noise frequency range of the sound insulation structure.

[0060] A partition 104 is disposed on the first surface 101 a of the main body 101 , and the partition 104 at least covers a portion of the opening of the chamber 102 , so that the partition 104 forms a through opening 101 a - 1 at the opening thereof.

[0061] Among them, in the previous embodiment, the Helmholtz resonator structure can also be composed of a main body 101 and a partition 104. The partition 104 is fixed on the surface of the main body 101. There is a through hole 101a-1 running through the partition 104 at the cavity 102 on the surface of the main body 101 to form a Helmholtz resonator structure. When the sound wave enters the cavity 102 through the through hole 101a-1, it is then rebounded by the inner wall of the cavity 102 or the rebound member 103, and collides with the sound wave entering the cavity 102 from the through hole 101a-1, thereby consuming energy.

[0062] A plurality of groups of rebound members 103 are disposed inside the chamber 102 .

[0063] Furthermore, a plurality of groups of rebound members 103 may be provided according to the scene noise frequency band used by the sound insulation structure 100 .

[0064] The mass block 103 b inside the chamber 102 may be any one or more combinations of a cuboid, a cylinder, a triangular prism, etc.

[0065] Among them, the sound insulation and vibration reduction effect of the rebound member 103 is related to its own frequency and vibration mode. Different mass blocks 103b of different shapes, masses, sizes, etc. can be set inside the chamber 102 according to different usage environments to improve the absorption frequency bands of different sound waves.

[0066] In summary, when the sound wave passes through the opening 101a-1 and enters the chamber 102, the sound wave begins to hit all the mass blocks 103b inside. At the same time, the sound wave reflected back from the inner wall of the chamber 102 will also hit the corresponding mass blocks 103b, eventually forming a balanced state, causing the internal sound waves to be consumed.

[0067] Example 4

[0068] Reference Figures 1 to 8 , which is the fourth embodiment of the present invention, is different from the other embodiments in that: the sound insulation structure is applied inside the double-layer glass; it includes a sound absorbing component 200, including an outer layer of glass 201 and an inner layer of glass 202 respectively arranged on both sides of the sound insulation structure 100; and

[0069] The mounting assembly 300 is disposed on the periphery of the sound absorbing assembly 200 and the sound insulation structure 100 .

[0070] The sound insulation structure 100 is installed between two glass plates to ensure that there is no direct contact between the two glass plates and that they are arranged parallel to each other. The two glass plates are an outer glass 201 and an inner glass 202. The outer glass 201 and the inner glass 202 are indirectly connected by an installation component 300. The installation component 300 can be externally fixed by a glass installation frame.

[0071] The inner wall of the mounting assembly 300 is attached to the upper surface of the outer glass 201 and the lower surface of the inner glass 202. When the sound waves pass through the outer glass 201, the sound insulation structure 100 consumes the sound waves, further weakens the sound waves, and reduces the impact of noise.

[0072] The sound insulation structure 100 is fixed on the inner layer of glass 202 by the second elastic member 204 ; a hollow layer 203 is formed between the sound insulation structure 100 and the outer layer of glass 201 , and the hollow layer 203 is filled with dry gas.

[0073] Among them, the first surface 101a of the main body 101 in the sound insulation structure 100 faces the outer glass 201, and the other surface is attached to the surface of the inner glass 202 through the second elastic member 204. The second elastic member 204 is made of damping material, and this solution uses PVB film; when the noise sound wave propagates to the PVB film, part of the sound wave energy is absorbed by the surface of the PVB film, and part of the sound wave energy is absorbed by the internal damping of the PVB film, and the sound wave energy is converted into weak heat energy, thereby achieving the effect of sound insulation. The addition of PVB damping material improves the overall vibration reduction performance of the window and can reduce the possibility of structural vibration caused by external loads; a hollow layer 203 is formed between the sound insulation structure 100 and the outer glass 201, and the dry gas filled in the hollow layer 203 is an inert dry gas, because the sound wave propagates fast inside it, which can further enhance the "viscous loss" effect at the port 101a-1, and the hollow layer 203 can also be heat-insulated and well absorb high-frequency noise.

[0074] When the sound waves enter the hollow layer 203 through the opening 101a-1 and are absorbed by the sound insulation structure 100, a portion of the sound waves may pass through the sound insulation structure 100 and then be absorbed by the second elastic member 204 to ensure the overall sound insulation effect.

[0075] Example 5

[0076] Reference Figures 1 to 10 , which is the fifth embodiment of the present invention, in the previous embodiment, the sound absorbing assembly 200 further includes a sealing member 205 provided between the outer glass 201 and the inner glass 202;

[0077] The sealing member 205 includes an aluminum spacer 205a between the outer glass 201 and the inner glass 202, and the aluminum spacer 205a is installed between the outer glass 201 and the inner glass 202 by means of a first sealant 205b;

[0078] The outer periphery of the sealing member 205 is wrapped with a second sealing adhesive 206;

[0079] The interior of the aluminum spacer 205 a is filled with a molecular sieve 207 .

[0080] In order to ensure the sealing of the hollow layer 203, two layers of sealing treatment are performed around the hollow layer 203. The sealing member 205 can wrap the hollow layer 203, the sound insulation structure 100 and the second elastic member 204, that is, the two side walls of the sealing member 205 are respectively attached to the outer glass 201 and the inner glass 202; or the sealing member 205 can wrap the hollow layer 203, that is, the two side walls of the sealing member 205 are attached to the outer glass 201 and the main body 101; Figure 8As shown, this embodiment adopts the first situation, that is, the sealing member 205 can wrap the hollow layer 203, the sound insulation structure 100 and the second elastic member 204; wherein, the side wall of the aluminum spacer 205a is connected to the outer glass 201 through the first sealant 205b, and the other side is connected to the inner glass 202 through the first sealant 205b, so that the hollow layer 203 is isolated from the outside, and at the same time, the surface of the aluminum spacer 205a close to the outside is wrapped with the second sealant 206, and the second sealant 206 is respectively attached to the surface of the outer glass 201 and the inner glass 202; the advantage of this is that the internal gas of the hollow layer 203 is prevented from exchanging with the outside, so as to ensure the dryness of the internal gas.

[0081] The interior of the aluminum spacer 205a is filled with a molecular sieve 207. It should be noted that the molecular sieve 230 is a desiccant, generally made of aluminosilicate. The first sealant 205b is generally made of PIB (butyl rubber), and the second sealant 206 can be made of silicone structural sealant.

[0082] The main function is to improve the overall vibration reduction performance of the window, reduce the possibility of structural vibration caused by external loads, and improve the sealing inside the hollow layer 203.

[0083] Since the sound insulation glass 200 and the installation assembly 300 are rigidly connected, external vibration may damage the overall structure. In order to reduce the damage to the overall structure caused by external factors, the installation assembly 300 includes an installation frame 301 that wraps the sound absorbing assembly 200; a third elastic member 302 that is attached between the sound absorbing assembly 200 and the inner wall of the installation frame 301; and a connection frame 303 that wraps the outer walls of the outer glass 201 and the inner glass 202, wherein the third elastic member 302 is also filled between the connection frame 303 and the installation frame 301;

[0084] Among them, Fig.10 As shown, a third elastic member 302 is filled between the sound absorbing component 200 and the left and right inner walls of the installation frame 301, and a third elastic member 302 is also filled between the connecting frame 303 and the left and right inner walls of the installation frame 301; the third elastic member 302 is made of a vibration-damping material, such as rubber, spring, fiber, etc.

[0085] In order to further reduce the impact of external vibration on the overall structure, a vibration-damping block 304, such as rubber, spring, fiber, etc., is filled between the connecting frame 303 and the bottom inner wall of the mounting frame 301; and a heat-insulating material, such as PVC insulation strips, nylon insulation strips, etc., is filled between the vibration-damping block 304 and the left and right inner walls of the mounting frame 301 for heat preservation.

[0086] Further, if Fig.10As shown, a sealing strip 305 is covered on the upper surface of the third elastic member 302 . The sealing strip 305 is a sealing strip 305 commonly used for glass sealing in the market; that is, a circle of the sealing strip 305 is wrapped around the inner wall of the third elastic member 302 .

[0087] The glass body of the present invention utilizes a combination of "cavity + vibrator", which can provide good sound insulation effect for medium and low frequency noise, effectively preventing medium and low frequency noise from being transmitted into the room through the window glass. The "vibrator" can also reduce the low-frequency vibration of the glass in a relatively small size, reducing the possibility of secondary noise generated by the window due to low-frequency vibration.

[0088] The "vibrator" of the present invention adopts the principle of local resonance. When low-frequency sound waves propagate and are incident on the main body 101, the "vibrator" in the chamber 102 will begin to vibrate due to resonance, and the force of the sound waves on the main body 101 and the reaction force generated by the vibration of the "vibrator" will cancel each other out, and the vibration of the main body 101 will be weakened, thereby achieving the sound insulation effect of low-frequency noise. The control of low-frequency vibration is similar. The low-frequency vibration is transmitted to the main body 101 inside the soundproof window glass, and the "vibrator" has a good inhibitory effect on the low-frequency vibration.

[0089] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed.
