[0002] Architecture includes two major categories: houses and structures. The objects of architecture range from comprehensive environmental design and construction including regional planning, urban planning, landscape design, and related construction processes before the formation of a community to the production of indoor furniture and small objects. In buildings, sound insulation panels are often installed on the walls to reduce the impact of outdoor noise on the interior or the impact of indoor noise on other residents.

[0003] The announcement number authorized by China is CN220580328U, and it is named a patent for a sound insulation building board. The device includes a metal steel plate, a light steel keel is arranged on the outside of the metal steel plate, a first sound insulation layer is arranged on the outside of the light steel keel, a second sound insulation layer is arranged on the outer wall of the first sound insulation layer, a gypsum board is arranged on the other side of the second sound insulation layer, and a third sound insulation layer is arranged on the other side of the gypsum board. The second sound insulation layer is a honeycomb sound insulation board, which has a good sound absorption effect, because there are many closed small chambers with partitions inside, which block the airflow and the sound waves, increase the sound absorption coefficient, and have a good sound insulation and noise reduction effect. The third sound insulation layer is sound insulation cotton, which can effectively soundproof and has good moisture-proof and heat insulation properties. The sound-absorbing board is made of metal and has a plurality of evenly distributed sound-absorbing holes on the outer wall. It has high strength. Sound waves can penetrate into the sound-absorbing material along the sound-absorbing holes and rub against the edge of the holes to convert sound energy into heat energy. According to the law of conservation of energy, more heat energy reduces sound energy, and the sound insulation and noise reduction effect is good.

[0004] Although the above device has good sound insulation and noise reduction effect, there are still some problems when using the device:

[0005] 1. The device does not have a humidity control and moisture-proof mechanism and cannot adjust the indoor humidity. In addition, the fine iron powder and sound insulation cotton inside it are prone to moisture, rust or mold.

[0006] 2. The device does not have a pyramid-shaped reflection mechanism. When sound waves reach the vicinity of the device, it is easy to produce echoes, standing waves and sound focusing phenomena, causing noise focusing or affecting the sound quality of indoor audio equipment and other sound-generating equipment.

[0007] In view of the above situation, technical innovation is carried out on the basis of the existing sound insulation building panels. Utility Model Content

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sound insulation building board, comprising a wedge layer and a humidity regulating layer, a sound absorbing board is fixed to one side of the wedge layer, and sound absorbing holes are opened on the inner wall of the sound absorbing board, the humidity regulating layer is fixed to the side of the wedge layer away from the sound absorbing board, the sound absorbing layer is fixed to the side of the sound absorbing board away from the wedge layer, and a sound insulation component is fixed to the side of the sound absorbing layer away from the sound absorbing board, the sound insulation component comprises a sound insulation layer and a reflection block, and the reflection block is fixed to the outside of one side of the sound insulation layer.

[0010] Furthermore, the wedge layer is made of porous stainless steel sound-absorbing wedge material, and the cross section of a single wedge is trapezoidal.

[0011] Furthermore, the sound absorbing board is made of honeycomb foam ceramic material, and a plurality of sound absorbing holes are provided on the sound absorbing board.

[0013] Furthermore, the sound absorbing layer is made of polyester fiber, and the sound absorbing layer and the sound absorbing board are bonded and fixed.

[0014] Furthermore, the sound insulation layer is made of stainless steel plate, and the reflective block is pyramid-shaped.

At the same time, the device is provided with a reflection mechanism, which can reflect sound waves to prevent the generation of echoes, standing waves and sound focusing phenomena, which is beneficial to improving the practicality of the device.

[0016] 1. The utility model provides a wedge layer, a sound-absorbing board, sound-absorbing holes and a humidity-adjusting layer. When the air humidity is high, the humidity-adjusting layer can effectively absorb moisture in the air, causing wall corrosion, and can reduce the humidity in the room. When the air is relatively dry, the moisture in the humidity-adjusting layer evaporates, thereby increasing the humidity in the room, avoiding a sudden rise or fall in the air humidity, and achieving the regulation of the indoor air humidity. At the same time, it can also prevent moisture from corroding the interior of the device. The wedge layer is made of stainless steel and has a certain thickness, which effectively separates the humidity-adjusting layer and the sound-absorbing board, further reducing the influence of moisture on the interior of the device. The sound-absorbing board is made of ceramic material. Since the sound-absorbing board and the wedge layer are both made of materials with weak hygroscopicity, the dryness inside the device is further improved. Through the above structure, it can effectively prevent moisture from corroding the wallboard, causing wallboard corrosion and wall mold, which is beneficial to improving the service life of the wall and the device.

[0017] 2. The utility model arranges the wedge layer, the sound-absorbing board, the sound insulation component, the sound insulation layer and the reflection block. When the sound wave passes through the wedge layer and the sound-absorbing board, the wedge layer and the sound absorption board can effectively absorb the sound energy of the sound wave, thereby reducing the sound intensity. When the remaining sound wave reaches the sound insulation component, compared with the plane reflection, the pyramid-shaped reflection block can reflect the sound energy in different directions to prevent the occurrence of echoes and standing waves, and avoid sound focusing, thereby improving the sound insulation effect of the device. The sound insulation layer can effectively isolate the remaining sound waves, further improving the sound insulation effect of the device. Through the above structure, the device can reflect the sound wave to prevent the occurrence of echoes, standing waves and sound focusing, which is conducive to improving the practicality of the device.

[0024] like Figure 1 and Figure 2 As shown, a sound insulation building board includes a wedge layer 1 and a humidity regulating layer 4, a sound absorbing board 2 is fixed to one side of the wedge layer 1, and a sound absorbing hole 3 is opened on the inner wall of the sound absorbing board 2, the humidity regulating layer 4 is fixed to the side of the wedge layer 1 away from the sound absorbing board 2, a sound absorbing layer 5 is fixed to the side of the sound absorbing board 2 away from the wedge layer 1, and a sound insulation component 6 is fixed to the side of the sound absorbing layer 5 away from the sound absorbing board 2, the sound insulation component 6 includes a sound insulation layer 601 and a reflection block 602, and a reflection block 602 is fixed to the outside of one side of the sound insulation layer 601. When the air humidity is high, the humidity regulating layer 4 can effectively absorb moisture in the air, causing wall corrosion, and can also reduce the humidity in the room. When the air is relatively dry , the moisture in the humidity-adjusting layer 4 evaporates, thereby increasing the room humidity, avoiding a sudden rise or fall in air humidity, and realizing the regulation of indoor air humidity. At the same time, it can also prevent moisture from corroding the interior of the device. The wedge layer 1 is made of stainless steel and has a certain thickness, which effectively separates the humidity-adjusting layer 4 and the sound-absorbing panel 2, further reducing the influence of moisture on the interior of the device. The sound-absorbing panel 2 is made of ceramic material. Since the sound-absorbing panel 2 and the wedge layer 1 are both made of materials with weak hygroscopicity, the dryness inside the device is further improved. Through the above structure, it can effectively prevent moisture from corroding the wallboard, causing the wallboard to rot and the wall to mold, which is beneficial to improving the service life of the wall and the device.

[0025] like Figure 1 and Figure 2As shown, the wedge layer 1 is made of porous stainless steel sound-absorbing wedge material, and the cross section of a single wedge is trapezoidal, the sound-absorbing board 2 is made of honeycomb foam ceramic material, and a plurality of sound-absorbing holes 3 are provided on the sound-absorbing board 2, the humidity-adjusting layer 4 is made of diatom mud insulation board material, and the humidity-adjusting layer 4 and the wedge layer 1 are bonded and fixed, the sound-absorbing layer 5 is made of polyester fiber material, and the sound-absorbing layer 5 and the sound-absorbing board 2 are bonded and fixed, the sound-insulating layer 601 is made of stainless steel plate material, and the reflecting block 602 is pyramid-shaped.

[0026] In summary: when using the sound insulation building board, first, the wedge layer 1 is similar to the wedge structure commonly found in the walls of soundless rooms used for acoustic testing and audio-visual work recording. In this device, the wedge layer 1 is thinner and has a higher density, thereby avoiding excessive impact on the thickness of the wall. At the same time, the cross-section of the wedge layer 1 is a trapezoid rather than a triangle, which effectively increases the contact area between the wedge layer 1 and the humidity regulating layer 4, making it easier to bond the humidity regulating layer 4. The sound absorbing board 2 is made of honeycomb foam ceramic material. When sound waves pass through the sound absorbing board 2 and the sound absorbing holes 3, the humidity regulating layer 4 is made of diatom mud insulation board material, which has good humidity regulating and heat preservation effects and is flame retardant. The sound waves will be repeatedly reflected in the countless tiny holes in the honeycomb foam ceramic, thereby absorbing sound energy, improving the sound absorption effect, and reducing the sound transmission rate. The sound absorbing layer 5 is made of polyester fiber, which can also effectively absorb the sound energy of sound waves. When the air humidity is high, the humidity regulating layer 4 can effectively absorb moisture in the air, causing wall corrosion, and at the same time can reduce the humidity in the room. When the air is relatively dry, the moisture in the humidity regulating layer 4 The air evaporates, thereby increasing the humidity in the room, avoiding a sudden rise or drop in air humidity, and achieving the regulation of indoor air humidity. At the same time, it can also prevent moisture from eroding the interior of the device. The wedge layer 1 is made of stainless steel and has a certain thickness. It effectively separates the humidity regulating layer 4 and the sound absorbing board 2, further reducing the impact of moisture on the interior of the device. The sound absorbing board 2 is made of ceramic material. Since the sound absorbing board 2 and the wedge layer 1 are both materials with weak hygroscopicity, the dryness inside the device is further improved. When the sound wave passes through the wedge layer 1 and the sound absorbing board 2, the wedge layer 1 and the sound absorbing board 2 can effectively absorb the sound energy of the sound wave, thereby reducing the sound intensity. When the remaining sound wave reaches the sound insulation component 6, compared with the plane reflection, the pyramid-shaped reflection block 602 can reflect the sound energy in different directions to prevent echoes and standing waves, avoid sound focusing, thereby improving the sound insulation effect of the device. The sound insulation layer 601 can effectively isolate the remaining sound waves, further improving the sound insulation effect of the device. This is the working principle of the sound insulation building board.
