Sound absorption composite structure unit and sound absorber array with same
The invention provides a sound absorption composite structure unit and a sound absorber array with the same. The sound absorption composite structure unit comprises a resonance structure and a micro-perforated sound absorption structure, wherein the resonance structure comprises a face plate, a left side plate, a back plate and a right side plate, and the face plate, the left side plate, the backplate and the right side plate are the same in height and are sequentially and fixedly connected to define a frame of the sound absorption composite structure unit; and the micro-perforated sound absorption structure comprises a left micro-perforated sound absorption plate and a right micro-perforated sound absorption plate, and the sound absorption composite structure unit further comprises a porous sound absorption structure. The invention provides the sound absorber array with the sound absorption composite structure unit. According to the sound absorption composite structure unit and the sound absorber array with the same, the respective advantages of three types of sound absorption structures are integrated, the problems that when the porous sound absorption structure and the micro-perforated sound absorption structure are applied to a severe scene, the protection surface is increased, and the sound absorption performance is considered are effectively solved, the sound absorptioncomposite structure unit and the sound absorber array with the same have the advantages of convenience in processing and preparation, simplicity in installation and implementation and excellent multidirectional low-frequency sound-absorbing performance.
本发明提供一种吸声复合结构单元及具有其的吸声体阵列，吸声复合结构单元包括共振结构和微穿孔吸声结构；共振结构包括面板、左侧板、背板和右侧板，其中面板、左侧板、背板和右侧板的高度相同并依次固定连接围成吸声复合结构单元的框架；微穿孔吸声结构包括左微穿孔吸声板和右微穿孔吸声板；吸声复合结构单元还包括多孔吸声结构。本发明提供的吸声体阵列具有上述吸声复合结构单元。根据本发明的一种吸声复合结构单元及具有其的吸声体阵列，综合三类吸声结构各自的优势，有效解决多孔吸声结构和微穿孔吸声结构在应用于恶劣场景时增加防护面和兼顾吸声性能的问题，具有加工制备方便、安装实施简单、多方向低频吸声性能优异的优点。
