Sound insulation barrier based on acoustic metamaterial
The invention discloses a sound insulation barrier based on acoustic metamaterial. The sound insulation barrier comprises a grating support (1) and an elastic film (2), the two side faces of the elastic film (2) are each coated with a coating, the grating support (1) comprises a first frame and a second frame, and the first frame and the second frame are each provided with a plurality of rows and columns of through openings (5) which are formed at equal intervals and are of a plate-shaped structure, the first frame is connected with the second frame through the elastic film (2), two side surfaces of the elastic film (2) are respectively adhered to the side surface of the first frame and the side surface of the second frame, a plurality of balancing weights (3) are arranged on one side surface of the elastic film (2), and each balancing weight (3) is positioned in each through hole (5) of the first frame. Compared with the prior art, the method has the advantages of low implementation difficulty, good sound insulation effect, wide application range and the like.
本发明涉及一种基于声学超材料的隔声屏障，包括格栅支架(1)和弹性薄膜(2)，弹性薄膜(2)的两侧面上均涂覆有涂层，所述格栅支架(1)包括分别设有多排多列等距离设置的贯穿口(5)的板状结构的第一框架和第二框架，第一框架通过弹性薄膜(2)与第二框架连接，性薄膜(2)的两个侧面分别粘附在第一框架的侧面和第二框架的侧面上，且弹性薄膜(2)的一侧面上设有多个配重块(3)，各配重块(3)位于第一框架的各贯穿口(5)内。与现有技术相比，本发明具有实施难度低，隔音效果好，适用范围广等优点。
