If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

Referring to fig. 1, a sound-absorbing board, it includes panel 1 that is "great wall" form by sheet metal formation cross-section, sheet metal is the steel sheet, other convertible panel such as aluminum plate and plastic-aluminum plate, in order to reach better bending effect, sheet metal thickness adopts 0.3 ~ 3mm, if adopt the best thickness of steel sheet to be 0.7mm, if adopt the best thickness of aluminum plate to be 1.2mm, if adopt the best thickness of plastic-aluminum plate to be 9mm, panel 1 is including circulating setting's panel front 11, panel first side wall 12, panel bottom 13 and panel second side wall 14, form sound guide notch 15 between the adjacent panel front 11, the best width requirement is panel front 11 respectively: 20mm, panel first side wall 12: 10mm, panel bottom 13: 4mm, panel second sidewall 14: 10mm, the height of panel first lateral wall 12 and panel second lateral wall 14 is 10mm, be provided with a plurality of through-holes 16 on panel first lateral wall 12 and the panel second lateral wall 14, the cross-sectional shape of through-hole 16 is circular, triangle-shaped, quadrangle, pentagon or other polygon or the mixture of two or more than shape, and the preferred shape is circular, and the diameter is 0.1 ~ 10mm, and the preferred diameter is 2 mm. The arrangement of the through holes 16 may be single row or multiple rows.

The ratio of the sound guide notch 15 to the front face 11 of the panel and the sound guide notch 15 is controlled within 22%, and the sound absorption effect is consistent with the sound absorption performance of the porous material filled in the sound guide notch when the opening ratio exceeds 20% according to the acoustic principle. The target frequency curve can be obtained by adjusting the dimensions of the front face 11 of the panel and the sound guide slot 15.

Referring to fig. 2, fig. 2 is an expanded view of the sound-absorbing panel before it is bent, and the entire area of the plurality of through holes 16 formed in the first side wall 12 and the second side wall 14 of the faceplate is identical to the sound guide notches 15, so as to ensure the sound-transmitting effect.

In order to conveniently splice the sound-absorbing boards together, one end of the panel 1 is provided with a mounting and fixing part 2, the other end of the panel is provided with a bending part 3, the mounting and fixing part 2 comprises a screw mounting part 21 and a mortise 22, the bending part 3 comprises a tenon 31 inserted into the mortise 22, and during splicing, referring to fig. 3, firstly, screws are adopted to penetrate through the screw mounting part 21 to mount the sound-absorbing boards on a keel 4 or other building base materials, the installation of the adjacent sound-absorbing boards can be completed as long as the tenon 31 is inserted into the mortise 22, and the mortise 22 and the tenon 31 are bent inwards and are arranged relatively, so that the screws can be shielded by the adjacent sound-absorbing boards after splicing, and the integrally consistent appearance effect is achieved. Each batten only needs to be fixed by one row of nails, so that the cost is saved and the installation is fast. Light gauge steel self-tapping screw's in the engineering nail cap is general to be 5mm, when leading the 15 width in sound notch and be less than 5mm, must change into the screw of the small size of unusual use, is 2mm then more difficult when leading the sound notch to influence the installation effectiveness, this tenon fourth of twelve earthly branches structure effectively solves this problem, and the installation is convenient.

In order to obtain a better decorative effect of the product, the surface of the steel plate can be treated by galvanizing rust-proof treatment, spraying or film pasting and other color decoration treatments.

Referring to fig. 1, the panel first sidewall 12 and the panel second sidewall 14 may be disposed perpendicular to the panel bottom 13, and according to actual needs, referring to fig. 4, the panel first sidewall 12 and the panel second sidewall 14 may be disposed obliquely to the panel bottom 13, and of course, referring to fig. 5, the panel front 11, the panel first sidewall 12 and the panel second sidewall 14 may be disposed in an arc structure. The design also belongs to a great wall-shaped model, and the sound absorption effect can be achieved.

Referring to fig. 6, 7, 8 and 9, the front panel 11 may be made into other structures, such as an arc or V-shaped design, according to actual needs.

Referring to fig. 10, 11, 12, 13 and 14, the front surface 11 of the panel may be formed to have a concave-convex structure according to actual needs.

Referring to fig. 15, the panel first side wall 12 and the panel second side wall 14 are inclined in such a manner that the structure of fig. 15 can be adopted in addition to the structure of fig. 4.

Referring to fig. 16, 17, 18, 19, and 20, the panel first sidewall 12 and the panel second sidewall 14 may be provided in a curved structure.

Referring to fig. 21 and 22, the panel bottom 13 may be a curved structure according to actual needs.

Referring to fig. 23, the through holes 16 may be crosswise disposed on the first sidewall 12, the panel second sidewall 14, and the panel bottom 13.

Referring to fig. 24, 25, 26 and 27, the lengths of the panel front 11, the panel first sidewall 12, the panel bottom 13 and the panel second sidewall 14 may be changed according to actual needs.

Referring to fig. 28, 29, 30 and 31, the shapes and lengths of the panel front 11, the panel first sidewall 12, the panel bottom 13 and the panel second sidewall 14 may be changed and combined according to actual needs.
