Acoustic panel with unit structure

一种单元结构的吸声板

Abstract

本发明涉及一种单元结构的吸声板,它包括超微孔吸声面板、侧边板和吸声背板,所述超微孔吸声面板的边缘部位通过侧边板与吸声背板连接并由此构成吸声共振腔;其特征在于,所述吸声共振腔的内部设有与其平行的吸声金属薄膜或带纳米微球的吸声金属薄膜。本发明不仅具有吸声频带宽和降噪效果好的优点,而且具有结构简单、工艺制造和装配使用简便可靠的优点。本发明的吸声板适用各类建筑物内需要吊顶和墙面装饰的场合,特别适用于需要强吸声降噪的场合。
The invention relates to an acoustic panel with a unit structure. The acoustic panel comprises an ultramicropore acoustic panel, a side edge plate and an acoustic back plate. The edge part of the ultramicropore acoustic panel is connected with the acoustic back plate through the side edge plate to form a sound absorption resonant cavity. The acoustic panel is characterized in that an sound absorption metal film parallel to the sound absorption resonant cavity or an sound absorption metal film with nano microspheres is arranged in the sound absorption resonant cavity. The acoustic panel not only has the advantages of wide sound absorption bandwidth and good noise reduction effects, but also has the advantages of simple structure and simplicity, convenience and reliability in process manufacture and assembly use. The acoustic panel is suitable for the occasions in various buildings where ceiling hanging and wall decoration are required, and particularly suitable for the occasions where high sound absorption is required.
