Whether it is day or night, it is quite annoying. Others are the generator room, the machine room, the factory or the KTV in the basement of the building. The source of noise, the pursuit of quality living environment, to provide a comfortable and quiet life, first of all must pay attention to the necessity of noise prevention and control in such places, and the traditional way of prevention and control Most of the objects use materials. This is because the fibrous sound absorbing material is elastic vibrating material. In the joint theory of membrane vibration and capillary sound absorption, the material will absorb sound waves and resonate, and each of the membrane materials will be incident. The sound wave is a branch and the sound impedance is connected in parallel, so that the sound-absorbing plate of the other 'rigid material is also a kind of For the soundboard, please refer to the fourth figure (4). The sound absorbing panel is installed on the ceiling light steel frame (4). The metal plate (3) ', the bad / side edge (31) is placed on The light steel frame of the ceiling (4) is abutted against the side of the 5 flange (41). The metal plate (3) is provided with a plurality of perforations (32) and is attached to the inner layer of the f-plate (3). The sound absorbing thin layer (3) of the soundproofing effect has a sound absorbing effect by the perforations (32) of the metal plate (3) and the sound absorbing layer (3). However, the above-mentioned sound absorbing panel may have the following defects in actual use: 1 Since the sound layer needs to be added with a sound absorbing layer in the inner layer, it can achieve the sound absorbing effect of the singer, so it is troublesome in assembling the operation. And the relative manpower and construction costs are also higher. 2· ^The sound-absorbing panel described above has a number of township perforations on the (four) board to allow the sound waves to pass through, and then absorbs the sound layer through the inner layer of the metal sheet to absorb the sound, but the sound field has many sound waves. It is directly reflected back into the room by the metal plate, so its sound absorption effect is not very good. SUMMARY OF THE INVENTION Therefore, in view of the above-mentioned sound absorbing panel, the present inventors need to install a sound absorbing layer, so that the operation trouble is high, and the sound wave is directly reflected back into the room by the metal plate, and the sound absorbing wire is not good, so this book With the help of years of accumulated expertise, technology and experience, we are constantly striving to improve and develop, thus inventing a kind of body-forming and quick assembly, and on the top and bottom respectively. The concave is provided with a plurality of micro-multi-curved appearance faces and micro-geometry holes, which cause the sound wave penetration loss, and the geometric micro-hole sound absorbing plate which has better sound absorption effect. The geometric microporous sound absorbing panel of the present invention mainly has a metal plate body. The top surface of the plate body is formed with a fine multi-curved surface, and the bottom surface of the plate body corresponds to the finer surface of the plate body. The surface of the curved surface is concave and has a micro-cone shape, and the air in the fine geometric hole slot (12) is formed by a large number of extremely thin coaxial column layers. The acoustic motion along the axial direction in each layer is limited by the inertia and the viscous resistance of the gradient of the axial velocity in the radial direction, so that the acoustic wave is incident on the plate body (^) and passes through the fine geometric hole (12). The a gas in the geometric hole groove (12) starts to vibrate corresponding to the number of cycles of the sound wave, and the air in the open space between the plate body (丨) and the floor layer (2) is compressed like a spring to compress, expand, and finely The inner wall of the geometric hole (12) is frictional to lose energy, and by the tapered surface of the fine geometric hole (12), the reflected sound waves collide with each other, so that the sound wave penetration loss is generated and the attenuation and disappearance are caused. This achieves the effect of sound absorption. For the implementation, please refer to the second and third figures. Since the plate body (1) is formed with a plurality of fine geometric holes (12), the sound waves transmitted from all directions are easy to touch the fine geometric holes. 2) the tapered surface, and the reflection is generated on the individual tapered surfaces, and the interspersed surfaces of the fine multi-curved surface (11;) and the fine geometric holes (12) are interlaced so that the reflected sound waves collide with each other. Attenuation occurs, and at the same time, even though part of the sound waves will penetrate the fine geometric holes (12) and the fine multi-curved surface (11), the fine geometric holes (12) and the fine multi-curved surface (11) are rather fine. Under the joint action of the capillary sound absorption principle, the three-dimensional cone extrusion principle and the white effort principle, the penetration loss of the sound wave is generated and the attenuation is generated. Moreover, since the top surface of the plate body (1) is formed into a fine multi-surface appearance The surface (11) allows the sound waves penetrating the fine geometric hole (12) and the fine multi-surface appearance surface 1) by the reflection collision between the floor layer (2) and the fine multi-curved surface (11) To make the sound wave more attenuated, plus the floor The sound wave between the layer (2) and the top surface of the plate body (1) hits the tapered surface of the fine multi-curved surface (11) and the fine geometric hole (12), and generates reflection on the other j-cone surface, and By interweaving the fine multi-surface appearance surface (I) and the fine 1341893 geometric hole (12) cone surface, the reflected sound waves collide with each other and attenuate 'simultaneously' even if some sound waves will penetrate the fine geometry The hole groove (12) and the fine multi-curved appearance surface (丨) are transmitted back to the indoor space. However, due to the fine-grained hole (12) and the fine multi-curved surface (丨丨), the principle of sound absorption and the principle of white effort are Under the combined action, the attenuation of the sound wave is caused, so that a relatively good sound absorbing effect can be achieved. However, the foregoing embodiments or drawings do not limit the shape of the plate material, the fine geometric hole groove and the fine multi-curved surface of the present invention or </ RTI> </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; In contrast, the present invention has the following advantages: 1. The metal sound absorbing panel of the present invention is formed into a metal plate body, and does not need to be provided with a sound absorbing layer, which has a good sound absorbing effect, and therefore is equivalent in composition. Convenient and fast. 2. The metal sound absorbing panel of the present invention has a plurality of fine geometric holes and a fine multi-curved surface, respectively, which are densely arranged on the bottom surface and the top surface thereof, and the micro-holes and the fine multi-curved surface are mutually Connected, using the principle of capillary sound absorption, the principle of three-dimensional cone extrusion and the principle of white effort, and the mutual refracting of the tapered surfaces of different degrees, which contribute to the mutual interference phenomenon and consume the kinetic energy of aerodynamics, not only can the reflected sound waves collide with each other. The attenuation "while" even if part of the sound waves will penetrate the fine geometric holes and the fine multi-surface appearance surface will cause the sound wave penetration loss, so that it can achieve better sound absorption effect. *In summary, the 'invention of the present invention can achieve the expected use efficiency' and the specific structure disclosed therein has not been seen in the similar product 9 1341893, nor has it been disclosed before the application, and has been fully met.
