Broadband ventilation and sound insulation window unit structure and application thereof
The invention relates to a broadband ventilation and sound insulation window unit structure and application thereof. The broadband ventilation and sound insulation window unit structure comprises an inner resonant cavity (1), a hollow pipe (2) and a thin-wall shell (3); the outer wall of the hollow pipe (2) is fixedly connected with the inner resonant cavity (1); the outer edge of the inner resonant cavity (1) is sleeved with the thin-wall shell (3); the inner resonant cavity (1) comprises a plurality of layers of hollow cylinders which are arranged on the outer wall of the hollow pipe (2), are stacked up and down and have the same structure and size; the outer edge of the bottom of each layer of hollow cylinder is provided with a horizontal partition plate (11) of an annular structure; and each layer of horizontal partition plate (11) is provided with a circumferential partition plate (4) and a radial partition plate (5) which are used for dividing each layer of resonant cavity into a plurality of resonant spaces. Compared with the prior art, the structure has the advantages that the sound insulation effect is improved, the working frequency band is wide, effective sound absorption can be improved while efficient sound insulation is achieved, and the application range is wide.
本发明涉及一种宽频通风隔声窗单元结构及其应用，宽频通风隔声窗单元结构包括内部谐振腔(1)、空心管(2)和薄壁外壳(3)，所述空心管(2)的外壁固定连接内部谐振腔(1)，所述内部谐振腔(1)的外缘套设有薄壁外壳(3)，所述内部谐振腔(1)包括设于空心管(2)外壁上的多层呈上、下堆叠的相同结构、尺寸的空心圆柱体，各层空心圆柱体的底部外缘分别设有环向结构的水平分隔板(11)，各层水平分隔板(11)上设有用以将各层谐振腔划分为多个谐振空间的周向分隔隔板(4)和径向分隔隔板(5)。与现有技术相比，本发明具有提高隔声效果、工作频带宽、在实现高效隔声同时可以提高有效吸声、适用范围广等优点。
