Description

Technical Field

[0001] This invention relates to the field of flooring technology, and in particular to a sound-insulating and sound-absorbing SPC stone plastic flooring and its manufacturing process. Background Technology

[0002] Flooring is a type of ground decoration material. Based on material, it can be divided into solid wood flooring, engineered wood flooring, bamboo flooring, glass flooring, metal flooring, etc. Based on type, it can be divided into raised access flooring, network flooring, and standard flooring, etc. Flooring can be broadly classified into six categories: solid wood flooring, engineered wood flooring, negative ion wood flooring, natural landscape feng shui flooring, laminate flooring, and bamboo flooring.

[0003] Stone-plastic composite (SPC) flooring is a high-quality, high-tech newly developed floor decoration material. It uses natural marble powder to form a solid base layer with a high-density, high-fiber mesh structure, and is covered with a highly wear-resistant polymer PVC layer, processed through hundreds of steps. In a society where living conditions are improving, those who value quality of life are increasingly choosing high-quality SPC flooring, making it more and more common. However, in the current use of flooring, footsteps, friction from external objects, and the intrusion of external noise create a noisy environment in the home. For an environmentally friendly lifestyle, the sound insulation and noise reduction technologies used in flooring are becoming increasingly sophisticated.

[0004] Chinese Patent Publication No. CN203066428U, published on July 17, 2013, discloses a PVC sound-absorbing floor, comprising a floor body and a buffer sound-absorbing layer disposed on the bottom surface of the floor body. The drawback of this technical solution is that while the sound-absorbing layer blocks sound from the floor body itself, it cannot effectively reduce the sound level.

[0005] In summary, a structure can be installed that allows sound to be gradually dissipated during transmission and finally introduced into the outside world. Summary of the Invention

[0006] The present invention aims to overcome the shortcomings of existing technologies in effectively reducing sound, and provides a sound-insulating and sound-absorbing SPC stone plastic floor with a structure that gradually dissipates sound during transmission, as well as its manufacturing process.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A sound-insulating and sound-absorbing SPC stone plastic flooring includes a first panel, a second panel, and a sound-diffusing block. The first panel and the second panel are detachably connected. The first panel has a first insertion groove, and the second panel has a second insertion groove. The positions of the first insertion groove and the second insertion groove are vertically corresponding. The first insertion groove and the second insertion groove form a cavity through the connection of the first panel and the second panel. Several insertion blocks are installed on both the first insertion groove and the second insertion groove. The sound-diffusing block is placed between the first panel and the second panel and has several insertion holes. The first panel and the second panel are connected to the sound-diffusing block through the cooperation of the insertion blocks and insertion holes.

[0009] This design allows the two boards, Board 1 and Board 2, to be connected to form a preliminary floor shape. The detachable connection between Board 1 and Board 2 is for easy connection and disassembly. Board 1 has a first insertion slot, and Board 2 has a second insertion slot. The positions of the first and second insertion slots are vertically aligned. When Board 1 and Board 2 are connected, the first and second insertion slots form a cavity, into which the sound-diffusing block can be placed. Several plug blocks are installed on the first and second plug slots, while several holes are provided on the sound-diffusing blocks. The connection between the first and second boards allows the plug blocks on the first and second boards to be inserted into the holes, so that the sound-diffusing blocks can be stably positioned between the first and second boards. This prevents the sound-diffusing blocks from shaking during use after the floor is installed. In this way, when the connected floor is in use, the sound generated by external factors such as friction or impact can be smoothly guided into the cavity. The sound-diffusing blocks in the cavity dissipate the energy of the sound, thus achieving the purpose of installing a structure that gradually dissipates the sound during transmission.

[0010] Preferably, an opening 1 is provided at the connection between the front ends of the first plate and the front ends of the second plate, and an opening 2 is provided at the connection between the rear ends of the first plate and the rear ends of the second plate. Both openings 1 and 2 communicate with the cavity, and the sound-diffusing block is placed inside the cavity. The sound-diffusing block has a wavy shape. This design, with the opening 1 at the connection between the front ends of the first plate and the front ends of the second plate, and the opening 2 at the connection between the rear ends of the first plate and the rear ends of the second plate, allows for communication with the cavity inside the floor formed by the connection of the first and second plates. In this way, the end of the sound-diffusing block inside the cavity can be placed outside the floor, which facilitates the connection between the two floorboards. The wavy shape of the sound-diffusing block increases its length, thereby increasing the distance the sound travels on the block and increasing the dissipation of sound energy during transmission.

[0011] Preferably, one end of the sound-diffusing block is equipped with a first plug-in block, which has a connecting groove. The first plug-in block passes through the first opening and is positioned outside the cavity. The other end of the sound-diffusing block 5 is equipped with a second plug-in block, which has a connecting block. The second plug-in block passes through the second opening and is positioned outside the cavity. The connecting block matches the connecting groove. This design allows for proper connection between the two ends of the sound-diffusing block through the first and second plug-in blocks. The first plug-in block passes through the first opening and is positioned outside the cavity, and the second plug-in block passes through the second opening and is positioned outside the cavity. This not only facilitates the dissipation of sound energy through the first and second plug-in blocks, but also ensures that the connecting groove on the first plug-in block matches the connecting block on the second plug-in block. This allows the two floorboards to be connected through the plug-in blocks and connecting grooves, improving the stability of the connection between the two floorboards.

[0012] Preferably, a sound-absorbing layer one is installed on the first plate, and a sound-absorbing layer two is installed on the second plate. This design allows the sound-absorbing layer one installed on the first plate to effectively receive the energy of the sound transmitted through the first plate, while the sound-absorbing layer two installed on the second plate can effectively receive the energy of the sound transmitted through the second plate, thus achieving a sound-absorbing effect.

[0013] Preferably, the first sound-absorbing layer is placed on the first insertion slot, the second sound-absorbing layer is placed on the second insertion slot, and several insertion blocks are connected to the first or the second sound-absorbing layer. This design, with the first sound-absorbing layer on the first insertion slot and the second sound-absorbing layer on the second insertion slot, and the arrangement of several insertion blocks connected to the first or the second sound-absorbing layer, allows the first and second sound-absorbing layers to not only receive energy from the first and second plates, but also to receive energy from the cavity. This ensures that during sound transmission, the sound is not only dissipated by the sound-dissipating blocks, but also absorbed by the first and second sound-absorbing layers, resulting in more effective sound attenuation.

[0014] Preferably, both the first and second panels are fitted with sound-insulating layers. Each sound-insulating layer has a through-hole at both its front and rear ends, and two openings (one and two) communicate with each other. This design, through the sound-insulating layers fitted on the first and second panels, achieves a sound insulation effect, preventing external sound from entering, thus providing the sound insulation function of the flooring. The through-holes at both ends of the sound-insulating layer are structural designs that allow openings one and two to communicate with the outside, enabling the insertion blocks one and two to pass smoothly through the sound-insulating layer and be placed on the outside, facilitating the insertion of the two floorboards.

[0015] Preferably, a protective sleeve is fitted onto the sound insulation layer. The protective sleeve has two through holes at its front and rear ends, with two through holes communicating with each of the two through holes. This design allows the protective sleeve to be fitted onto the sound insulation layer, protecting the layer and the floor structure within it from external interference and ensuring safety and reliability. The through holes at both ends of the protective sleeve are designed to connect the two through holes to the outside, allowing the two connecting blocks to pass smoothly through the protective sleeve and be placed outside, facilitating the connection of the two floorboards.

[0016] Preferably, the protective sleeve has several sound-gathering grooves, and the sound insulation layer has several sound-gathering holes. The positions of the sound-gathering holes correspond vertically to the positions of the sound-gathering grooves, and the sound-gathering holes are connected to the sound-gathering grooves. This design utilizes the sound-gathering grooves on the protective sleeve to concentrate the energy of the sound by taking advantage of the characteristic that sound is concentrated in a small diameter space. The sound-gathering holes on the sound insulation layer, which correspond vertically to the positions of the sound-gathering grooves, allow the sound gathered at the sound-gathering grooves to pass smoothly through the sound-gathering holes. Combined with the sound insulation effect of the sound insulation layer, this enhances the sound gathering effect.

[0017] Preferably, the sound-gathering hole is located at the upper end of the first panel, and the first sound-absorbing layer is located at the lower end of the first panel. Several limiting blocks are installed on the first sound-absorbing layer, symmetrically distributed around the first through-hole. The second sound-absorbing layer is located at the upper end of the second panel, and the lower end of the second panel is located within the sound insulation layer. The second sound-absorbing layer has several limiting grooves, each corresponding to a limiting block. This design allows the first and second panels to move towards each other, enabling the first sound-absorbing layer at the lower end of the first panel and the second sound-absorbing layer at the upper end of the second panel to move in the same direction. The limiting blocks installed on the first sound-absorbing layer can then smoothly insert into the limiting grooves on the second sound-absorbing layer, creating a mutual limiting effect between the first and second panels and reducing the probability of them separating. The several limiting blocks here are symmetrically distributed with the through hole one as the center. This ensures that the limiting effect of plate one and plate two is evenly distributed with the through hole one as the center. In this way, high temperature hot pressing can be performed at the insertion position of the limiting block and the limiting groove, so that the limiting block melts into the limiting groove after being heated by high temperature. After the temperature cools down, the connection work of plate one and plate two is completed.

[0018] This invention also provides a manufacturing process for sound-insulating and sound-absorbing SPC stone plastic flooring, specifically including the following steps:

[0019] Step 1: Make a first insertion slot at the lower end of the first board body, and connect a sound-absorbing layer 1 with several insertion blocks installed at the insertion slot. Make a second insertion slot at the upper end of the second board body, and connect a second sound-absorbing layer 2 with several insertion blocks installed at the insertion slot.

[0020] Step 2: Install plug-in block 1 and plug-in block 2 at both ends of the sound-diffusing block. Place the wavy sound-diffusing block between plug-in slot 1 and plug-in slot 2. Control plug-in slot 1 and plug-in slot 2 so that the plug-in blocks are aligned with the plug holes on the sound-diffusing block and inserted. This allows board 1 and board 2 to be properly connected to the sound-diffusing block. At the same time, several limiting blocks symmetrically distributed on sound-absorbing layer 1 around the through hole 1 are also inserted into the limiting grooves on sound-absorbing layer 2. Board 1 and board 2 are properly positioned. Then, perform high-temperature hot pressing at the insertion point of the limiting blocks and limiting grooves so that the limiting blocks melt and dissolve into the limiting grooves. After the temperature cools down, board 1 and board 2 are connected.

[0021] Step 3: Fit the sound insulation layer onto the structure formed by connecting panel 1 and panel 2. When fitting, two through holes and several sound-concentrating holes need to be made on the sound insulation layer so that plug-in block 1 and plug-in block 2 can pass smoothly through the through holes and be placed outside the sound insulation layer. Then, put a protective sleeve on the outside of the sound insulation layer. Two through holes and several sound-concentrating slots need to be made on the protective sleeve so that plug-in block 1 and plug-in block 2 can pass through the through holes and be placed outside the protective sleeve. The sound-concentrating slots correspond one-to-one with the sound-concentrating holes.

[0022] The beneficial effects of this invention are: it can achieve the purpose of installing a structure that gradually dissipates sound during transmission; it facilitates the connection between board one and board two; it increases the sound transmission distance; and it facilitates the smooth insertion of the two floorboards.

[0031] The invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 , Figure 2 and Figure 5 In the illustrated implementation example, a sound-insulating and sound-absorbing SPC stone plastic flooring includes a first panel 1, a second panel 2, and a sound-diffusing block 5. The first panel 1 and the second panel 2 are detachably connected. The first panel 1 is provided with a first insertion groove 3, and the second panel 2 is provided with a second insertion groove 4. The positions of the first insertion groove 3 and the second insertion groove 4 are vertically corresponding. The first insertion groove 3 and the second insertion groove 4 form a cavity through the connection of the first panel 1 and the second panel 2. Several insertion blocks 13 are installed on both the first insertion groove 3 and the second insertion groove 4. The sound-diffusing block 5 is placed between the first panel 1 and the second panel 2. The sound-diffusing block 5 is provided with several insertion holes 12. The first panel 1 and the second panel 2 are connected to the sound-diffusing block 5 through the cooperation of the insertion blocks 13 and the insertion holes 12.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an opening 6 is provided at the connection between the front end of board 1 and the front end of board 2, and an opening 7 is provided at the connection between the rear end of board 1 and the rear end of board 2. Both openings 6 and 7 communicate with the cavity. The sound-diffusing block 5 is placed inside the cavity, and the sound-diffusing block 5 has a wavy shape. A plug-in block 8 is installed at one end of the sound-diffusing block 5. The plug-in block 8 has a connecting groove 9. The plug-in block 8 passes through the opening 6 and is placed outside the cavity. A plug-in block 10 is installed at the other end of the sound-diffusing block 5. A connecting block 11 is installed on the plug-in block 10. The plug-in block 10 passes through the opening 7 and is placed outside the cavity. The connecting block 11 matches the connecting groove 9. A sound-absorbing layer 17 is installed on board 1, and a sound-absorbing layer 18 is installed on board 2. Sound-absorbing layer 17 is placed on insertion slot 3, and sound-absorbing layer 2 18 is placed on insertion slot 2 4. Several insertion blocks 13 are connected to sound-absorbing layer 17 or sound-absorbing layer 2 18. Sound-insulating layers 14 are fitted onto both panel 1 and panel 2. Each of the front and rear ends of the sound-insulating layer 14 has a through hole 1, and opening 6 and opening 7 are respectively connected to the two through holes 1. A protective sleeve 15 is fitted onto the sound-insulating layer 14. Each of the front and rear ends of the protective sleeve 15 has a through hole 2, and the two through holes 1 are respectively connected to the two through holes 2. The protective sleeve 15 has several sound-gathering grooves 16, and the sound-insulating layer 14 has several sound-gathering holes. The positions of the sound-gathering holes correspond vertically to the positions of the sound-gathering grooves 16, and the sound-gathering holes are connected to the sound-gathering grooves 16.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, the sound-gathering hole is located at the upper end of the first plate 1, and the sound-absorbing layer 17 is located at the lower end of the first plate 1. Several limiting blocks 19 are installed on the sound-absorbing layer 17. The limiting blocks 19 are symmetrically distributed around the first through hole. The second sound-absorbing layer 18 is located at the upper end of the second plate 2. The lower end of the second plate 2 is located inside the sound insulation layer 14. Several limiting grooves 20 are provided on the second sound-absorbing layer 18. The limiting grooves 20 correspond one-to-one with the limiting blocks 19.

[0035] This invention also provides a manufacturing process for sound-insulating and sound-absorbing SPC stone plastic flooring, specifically including the following steps:

[0036] Step 1: A insertion slot 3 is made at the lower end of the board 1, and a sound-absorbing layer 17 with several insertion blocks 13 is connected to the insertion slot 3. A insertion slot 24 is made at the upper end of the board 2, and a sound-absorbing layer 28 with several insertion blocks 13 is connected to the insertion slot 24.

[0037] Specifically: First, a slot 3 is made at the lower end of board 1, and a sound-absorbing layer 17 is connected to the slot 3. Several insert blocks 13 are evenly distributed on the sound-absorbing layer 17. Then, a slot 4 is made at the upper end of board 2, and a sound-absorbing layer 18 is connected to the slot 4. Several insert blocks 13 are also evenly distributed on the sound-absorbing layer 18. The insert blocks 13 on the sound-absorbing layer 17 and the insert blocks 13 on the sound-absorbing layer 18 can be set to be non-corresponding, so as to avoid mutual interference between the insert blocks 13 on the sound-absorbing layer 17 and the insert blocks 13 on the sound-absorbing layer 18 when board 1 and board 2 move towards each other.

[0038] Step 2: Install plug-in block 1 8 and plug-in block 2 10 at both ends of the sound-diffusing block 5 respectively. Place the wavy sound-diffusing block 5 between plug-in slot 1 3 and plug-in slot 2 4. Control plug-in slot 1 3 and plug-in slot 2 4 so that plug-in block 13 is aligned with the plug hole 12 on the sound-diffusing block 5 and inserted. This allows board 1 1 and board 2 2 to be connected to the sound-diffusing block 5. At the same time, several limiting blocks 19 symmetrically distributed on the sound-absorbing layer 17 with the through hole 1 as the center are also inserted into the limiting groove 20 on the sound-absorbing layer 2 18. Board 1 1 and board 2 2 are mutually limiting. Then, high temperature hot pressing is performed at the insertion position of limiting block 19 and limiting groove 20 so that limiting block 19 melts into the limiting groove 20. After the temperature cools down, board 1 1 and board 2 2 are connected.

[0039] Specifically: Next, plug-in block 1 8 and plug-in block 2 10 are installed at both ends of the sound-diffusing block 5. Plug-in block 1 8 has a connecting groove 9, and plug-in block 2 10 has a connecting block 11, which matches the connecting groove 9. When the first plate 1 and the second plate 2 move towards each other, the wavy sound-diffusing block 5 is placed between plug-in groove 1 3 and plug-in groove 2 4. This allows the plug-in blocks 13 on the first sound-absorbing layer 17 and the second sound-absorbing layer 2 18 to be smoothly inserted into the sockets 12 on the sound-diffusing block 5. The wavy structure design not only avoids interfering with the insertion of plug-in blocks 13 and sockets 12, but also increases the distance the sound travels on the sound-diffusing block 5, which helps to increase the dissipation of sound during transmission. Furthermore, some of the sockets 12 can be connected to plug-in blocks 13, while others are not connected at all. This also increases the dissipation area of ​​the sound during transmission on the sound-diffusing block 5, resulting in better dissipation. During the insertion of the insert 13 into the socket 12, several limiting blocks 19 symmetrically distributed on the sound-absorbing layer 17 around the through hole 1 are also inserted into the limiting groove 20 on the sound-absorbing layer 28. The plate 1 and plate 2 perform mutual limiting. The diameter of the limiting block 19 here can be smaller than the diameter of the limiting groove 20, but the length of the limiting block 19 is greater than the depth of the limiting groove 20. After the limiting block 19 is inserted into the limiting groove 20, the insertion position can be immediately subjected to high-temperature hot pressing, so that the limiting block 19 melts under the high-temperature hot pressing environment and dissolves into the limiting groove 20. When a little solution is squeezed out, the high-temperature hot pressing should be stopped in time, and the insertion position can be cooled. The melting limiting block 19 during cooling allows the plate 1 and plate 2 to be connected smoothly, stably and firmly.

[0040] Step 3: Fit the sound insulation layer 14 onto the structure formed by connecting panel 1 and panel 2. When fitting, two through holes and several sound-gathering holes need to be made on the sound insulation layer 14 so that the plug-in block 8 and plug-in block 10 can pass through the through holes and be placed outside the sound insulation layer 14. Then, fit the protective sleeve 15 on the outside of the sound insulation layer 14. Two through holes and several sound-gathering grooves 16 need to be made on the protective sleeve 15 so that the plug-in block 8 and plug-in block 10 can pass through the through holes and be placed outside the protective sleeve 15. The sound-gathering grooves 16 correspond one-to-one with the sound-gathering holes.

[0041] Specifically: Then, outside the structure formed by connecting panel 1 and panel 2, a sound insulation layer 14 is fitted. After fitting, through holes 1 need to be drilled at both ends of the sound insulation layer 14. The positions of through holes 1 and 2 need to correspond to the positions of through holes 1 and 2. Several sound-gathering holes are drilled at the top of the sound insulation layer 14. Next, a protective sleeve 15 is fitted over the sound insulation layer 14. Two through holes 2 also need to be drilled at both ends of the protective sleeve 15. The positions of the two through holes 2 need to correspond to the positions of through holes 1. Several sound-gathering grooves 16 are drilled at the top of the protective sleeve 15. The sound-gathering grooves 16 correspond to the positions of the sound-gathering holes 1 and 2. Correspondingly, this allows the plug-in block 8 and plug-in block 10 to pass through two through holes 2 and two through holes 1 respectively, and then through opening 6 and opening 7 respectively. This not only allows the two floorboards to be properly connected through the connecting block 11 on plug-in block 20 and the connecting groove 9 on plug-in block 8, enhancing the limiting effect of the two floorboards, but also increases the sound transmission distance of the sound-diffusing block 5, thereby increasing the energy dissipation during sound transmission. The wavy shape of the sound-diffusing block 5 inside the cavity is also a structural design that increases the sound transmission distance and energy dissipation during sound transmission. The sound-concentrating groove 16 utilizes the characteristic of sound concentrating in a small diameter space to gather the energy carried by the sound, allowing the energy carried by the sound to be concentrated on the plate 1 through the sound-concentrating hole, and then transmitted into the cavity under the guiding effect of the plate 1, facilitating the sound dispersion work of the sound-diffusing block 5. Moreover, the sound insulation layer 14 has a sound insulation effect, so the energy carried by the sound cannot be arbitrarily transmitted to any position on the board 1. This is the sound insulation effect of the floor, which also enhances the effect of the sound converging in the sound-gathering groove 16.

[0042] First, a slot 3 is made at the lower end of board 1, and a sound-absorbing layer 17 is connected to the slot 3. Several inserts 13 are evenly distributed on the sound-absorbing layer 17. Then, a slot 4 is made at the upper end of board 2, and a sound-absorbing layer 18 is connected to the slot 4. Several inserts 13 are also evenly distributed on the sound-absorbing layer 18. The inserts 13 on the sound-absorbing layer 17 and the inserts 13 on the sound-absorbing layer 18 can be set to be non-corresponding, so as to avoid mutual interference between the inserts 13 on the sound-absorbing layer 17 and the inserts 13 on the sound-absorbing layer 18 when board 1 and board 2 move towards each other.

[0043] Next, plug-in block 1 8 and plug-in block 2 10 are installed at both ends of the sound-diffusing block 5. Plug-in block 1 8 has a connecting groove 9, and plug-in block 2 10 has a connecting block 11, which matches the connecting groove 9. When the first plate 1 and the second plate 2 move towards each other, the wavy sound-diffusing block 5 is placed between plug-in groove 1 3 and plug-in groove 2 4. This allows the plug-in blocks 13 on the first sound-absorbing layer 17 and the second sound-absorbing layer 18 to be smoothly inserted into the sockets 12 on the sound-diffusing block 5. The wavy structure design not only avoids interfering with the insertion of the plug-in blocks 13 and sockets 12, but also increases the distance the sound travels on the sound-diffusing block 5, thus increasing the dissipation of sound. Furthermore, some of the sockets 12 can be connected to the plug-in blocks 13, while others are not connected, which also increases the dissipation area of ​​the sound during transmission on the sound-diffusing block 5, resulting in better dissipation. During the insertion of the insert 13 into the socket 12, several limiting blocks 19 symmetrically distributed on the sound-absorbing layer 17 around the through hole 1 are also inserted into the limiting groove 20 on the sound-absorbing layer 28. The plate 1 and plate 2 perform mutual limiting. The diameter of the limiting block 19 here can be smaller than the diameter of the limiting groove 20, but the length of the limiting block 19 is greater than the depth of the limiting groove 20. After the limiting block 19 is inserted into the limiting groove 20, the insertion position can be immediately subjected to high-temperature hot pressing, so that the limiting block 19 melts under the high-temperature hot pressing environment and dissolves into the limiting groove 20. When a little solution is squeezed out, the high-temperature hot pressing should be stopped in time, and the insertion position can be cooled. The melting limiting block 19 during cooling allows the plate 1 and plate 2 to be connected smoothly, stably and firmly.

[0044] Then, a sound insulation layer 14 is fitted onto the structure formed by connecting panel 1 and panel 2. After fitting, through holes 1 need to be drilled at both ends of the sound insulation layer 14. The positions of through holes 1 and 2 need to correspond to the positions of through holes 1 and 2. Several sound-gathering holes are drilled at the top of the sound insulation layer 14. Next, a protective sleeve 15 is fitted onto the sound insulation layer 14. Two through holes 2 also need to be drilled at both ends of the protective sleeve 15. The positions of the two through holes 2 need to correspond to the positions of through holes 1. Several sound-gathering grooves 16 are drilled at the top of the protective sleeve 15. The sound-gathering grooves 16 correspond to the sound-gathering holes 1. Accordingly, plug-in block 8 and plug-in block 10 can pass through two through holes 2 and two through holes 1 respectively, and then through opening 6 and opening 7 respectively. This not only allows the two floorboards to be properly connected through the connecting block 11 on plug-in block 210 and the connecting groove 9 on plug-in block 8, thus enhancing the limiting effect of the two floorboards, but also increases the sound transmission distance of the sound-diffusing block 5, thereby increasing the energy dissipation during sound transmission. The wavy shape of the sound-diffusing block 5 inside the cavity is also a structural design that increases the sound transmission distance and energy dissipation during sound transmission. The sound-concentrating groove 16 utilizes the characteristic of sound concentrating in a small diameter space to gather the energy carried by the sound, allowing the energy carried by the sound to be concentrated on the plate 1 through the sound-concentrating hole, and then transmitted into the cavity under the guiding effect of the plate 1, facilitating the sound dispersion work of the sound-diffusing block 5. Moreover, the sound insulation layer 14 has a sound insulation effect, so the energy carried by the sound cannot be arbitrarily transmitted to any position on the board 1. This is the sound insulation effect of the floor, which also enhances the effect of the sound converging in the sound-gathering groove 16.

[0045] The protective sleeve 15, panel 1, and panel 2 are all made of stone-plastic composite material. This utilizes the superior wear resistance and sound absorption properties of stone-plastic composite material, ensuring long-term use of the flooring and enhancing its sound insulation effect. The sound-diffusing block 5 can be made of copper because sound travels at a slow speed (3750 meters per second) on copper, making it easily dissipated. The sound insulation layer 14 can be made of foam particles, while the sound-absorbing layers 17 and 18 can be made of sound-absorbing cotton, allowing sound to be absorbed effectively by the cotton even under the sound insulation of the foam particles. The limiting block 19 can be made of aluminum. Aluminum has a low melting point of 660℃, making it easy to heat-melt, but it does not melt at room temperature.
