New Description: [New Technology Field] This creation is about a metal sound absorbing panel, especially a kind of sound wave that can reflect the collision and cause attenuation. Even if the sound wave penetrates, the penetration loss will occur. Innovative design of a metal sound absorbing panel with good sound absorption and fast set up. [Prior Art] As shown in the fourth figure, the conventional metal plate (91) is mounted on a ceiling light steel frame (92), and the metal plate (91) is disposed by its side edge (911). The ceiling light steel frame (92) abuts against the existing metal plate (91) above the flange (921), the metal plate (91) is provided with a plurality of perforations (912), and a soundproofing is added to the inner layer. The sound absorbing layer (913) of the effect has a sound absorbing effect by the perforations (912) and the sound absorbing layer (913) of the metal plate (91). However, when the above-mentioned prior art structure is actually used, it has the following shortcomings to be improved: I need to install a sound absorbing layer for the inner metal layer, so it is troublesome to set up the operation, and the relative manpower and construction The cost is also higher. 2. Although the metal plate has a plurality of perforations to allow the sound waves to pass through, and then absorb the sound layer through the inner layer of the metal plate to absorb the sound, to achieve the sound absorption effect, but because there are still many sound waves directly reflected by the metal plate Going back indoors, so its sound absorption is not very good. The reason is that the creators, in view of this, adhere to the actual design and manufacturing experience of relevant industries for many years, and research and improve the existing defects, and provide a brand-new metal sound absorbing panel, in order to improve all the existing missing. M289784 [New Content] This creation is about the bottom of a metal suction body. Your German, 9 anti-mainly in a metal plate cone, and the trr many conical bottoms have a circular micro-hole of the triangle in the wave (four) 4m The top surface is formed into a fine wave-shaped surface, and the triangular pyramid is formed; the upper periphery of the micro-shaped hole is also concavely reduced, and at the same time, the reflected white i-wave interferes with each other to generate attenuating holes, which is also true. The razor wave will make the elliptical shape of the toothed cone cone into a sound wave penetration loss, and the better sound absorption and faster group [embodiment] dew, the technical means of this creation can be more complete and clear = ~ and refer to the drawing and figure number, and the details are as follows: Board, mainly refer to the first to third figure 'The metal sound-absorbing pyramid of this creation (11/, in the bottom of the metal plate body (1) The concave is provided with a plurality of three circular micropores 1 respectively arranged at the cone bottom of each triangular cone (1)) with an -elliptical arrangement, #(12), such that many of the two pyramids (1) are 45 degrees to form a plum blossom hole in all directions. The sound wave hits the cone of the three Xiao: the mutual:> the surface produces reflection, and by the simultaneous and wrong of the three-cone surface, the reflected sound waves collide with each other to cause attenuation, so that some sound waves will be worn. Through the triangular cone (11), the elliptical shape of the cone bottom is fine, 2), but since the elliptical micro-hole (12) is relatively fine, it will cause the penetration loss of the sound wave and attenuate; in addition, the metal plate body (1) The top surface is formed into a fine wave-shaped surface (13) 'Order The sound wave of the elliptical micro-hole (12) on the bottom surface of the metal plate body (1) is made to attenuate the sound wave by the reflection between the floor layer (2) and the fine wave-shaped surface (13), and the wave is further attenuated. On the surface (13), a corresponding triangular cone (14) is also recessed around the upper portion of the micro-hole (12), so that the sound wave between the floor layer (2) and the top surface of the metal plate (1) hits the triangle. Cone surface of the cone (14), and reflection on the individual cone surfaces, and by the interleaving of the conical surfaces of the triangular cones (14), the reflected acoustic waves collide with each other and are more attenuated, and at the same time, even if there are partial sound waves The rounded micropores (12) penetrating the cone bottom of the triangular cone (14) are returned to the indoor space, but since the elliptical micropores are relatively fine, the sound wave penetration loss is caused and the decay occurs. For the implementation, please refer to the first to third figures. Since the triangular pyramids (11) provided on the bottom surface of the metal plate body (1) are 45 degrees to form the plum blossom hole arrangement, the sound waves transmitted from all directions are easy. A conical surface of the triangular cone (n) is encountered, and a reflection is generated on the individual conical surfaces, and by the interdigitation of the triangular conical (u) conical surfaces, the reflected acoustic waves collide with each other to cause fading, and at the same time, even Part of the sound wave will penetrate the elliptical burr hole (12) at the bottom of the triangular cone (11), but because the elliptical micro-hole (12) is quite fine, it will cause the penetration loss of the sound wave and cause attenuation. Since the metal plate body (1) < the surface of the member is formed into a fine wave-shaped surface (13), the sound wave of the elliptical micro hole (12) penetrating the bottom surface of the metal plate body (1) can be penetrated by the floor plate. The reflection between the layer (2) and the far fine wave-shaped surface (13) causes the sound wave to be more attenuated, and the contoured triangular pyramid is also recessed on the upper surface of the wave-shaped surface (13) corresponding to the elliptical micro-hole (12). (14), make the floor layer (2) and the metal plate body (!) The interfering sound waves hit the tapered surface of the triangular cone (14), and reflect on the individual conical surfaces, and the interlacing of the conical surfaces of the triangular conical (14) causes the reflected acoustic waves to collide with each other and attenuate more' At the same time, even if some of the acoustic waves will pass through the elliptical micro-holes (12) of the triangular cone (14) cone back to the indoor space, since the elliptical micro-holes (12) are relatively fine, they will create sound waves. The penetration loss causes attenuation, so it is quite good to absorb 7 M289784 sound through multiple attenuations. From the above, the structure and implementation of the creation can be seen that the creation has the following advantages: 1. The metal sound absorbing panel of the present invention is formed into a metal sheet body, so it is quite convenient and fast in assembly. 2. The metal sound absorbing panel of the present invention has a plurality of triangular cones densely covered on the bottom surface and the top surface thereof, and the cone bottoms of the upper and lower triangular cones are connected by an elliptical micro hole, wherein the triangular cone surface is not only The reflected sound waves collide with each other to cause attenuation, and at the same time, even if part of the sound waves will penetrate the elliptical micropores at the bottom of the triangular pyramid cone, the sound wave penetration loss will be caused, and the sound absorbing effect is better. In summary, the present embodiment can achieve the expected use efficiency, and the specific structure disclosed therein has not been seen in similar products, nor has it been disclosed before the application, and has fully complied with the provisions of the Patent Law. And the request, the application for a new type of patent in accordance with the law, please forgive the review, and grant the patent, it is really sensible.
