Wide silencing device and noise reduction plate for building
The invention discloses a wide silencing device and a noise reduction plate for a building, and the sound absorption structure comprises a sound absorption cavity, which is provided with a cavity with an upward opening; the cover plate is positioned above the sound absorption cavity and covers the opening of the cavity of the sound absorption cavity; one end of each partition plate is arranged on the cover plate, the other end of each partition plate extends downwards and is located in the cavity, and the at least one partition plate sequentially divides the cavity into at least two first cavities which are communicated with each other; wherein the cover plate is provided with a through hole, the hole wall of the through hole extends downwards from the lower surface of the cover plate to form a pipe part, a flow channel connected with the through hole is arranged in the pipe part, and the cavity of the sound absorption cavity is communicated with the outside of the sound absorption cavity through the flow channel. According to the application, the frequency range of sound absorption is adjusted by controlling the number of the first cavities in the sound absorption cavity, so that the effect of absorbing sound in a certain frequency range is achieved.
本发明公开了一种用于建筑物的宽幅消声装置及降噪板，所述吸声结构包括：吸声腔体，具有开口向上的空腔；盖板，位于吸声腔体的上方，且覆盖吸声腔体的空腔的开口；至少一个隔板，每个隔板的其中一端设置于盖板上，且另一端向下延伸并位于空腔内，至少一个隔板将空腔依次分隔为至少两个相连通的第一空腔；其中，盖板上设置有通孔，通孔的孔壁从盖板的下表面向下延伸形成管部，管部内具有与通孔连接的流道，吸声腔体的空腔通过流道与吸声腔体的外部连通。本申请通过对吸声腔体内的第一空腔的个数控制以调整吸声的频段范围，从而实现对某个频段吸声的效果。
