The invention discloses a resonance silencing window which comprises a window frame; limiting grooves are formed in the upper and lower inner walls of the window frame; the two limiting grooves are jointly in sealing and sliding connection with a movable glass plate; a fixed glass plate is fixedly connected with the upper and lower inner walls of the window frame in a sealing manner; the movable glass plate, the fixed glass plate and the window frame jointly define a resonance cavity; a plurality of resonance holes communicating with the resonance cavity are uniformly formed in the fixed glassplate; permanent magnet blocks are embedded at positions, corresponding to the limiting grooves, of the movable glass plate; and a first electromagnetic block and a second electromagnetic block are fixed to the two inner walls of each of the limiting grooves. The resonance silencing window has the following advantages: the resonance silencing window can automatically monitor the outdoor noise frequency, compares the outdoor noise frequency with the inherent frequency of an initial resonance structure, utilizes the first electromagnetic blocks or the second electromagnetic blocks to generate magnetic repulsive force to the permanent magnetic blocks so as to change the width Dy of the resonance cavity, and is excellent in resonance silencing effect to keep a quieter indoor environment.
本发明公开了一种共振消音窗，包括窗框，所述窗框的上下内壁均开设有限位槽，两个所述限位槽共同密封滑动连接有移动玻璃板，所述窗框的上下内壁密封固定连接有固定玻璃板，所述移动玻璃板、固定玻璃板和窗框之间共同构成共振腔，所述固定玻璃板内均匀开设有多个与共振腔连通的共振孔，所述移动玻璃板在限位槽的对应位置上嵌设有永磁块，所述限位槽的两侧内壁分别固定有第一电磁块与第二电磁块。优点在于：本发明可自动监测室外噪音频率，并与初始的共振结构的固有频率对比，利用第一电磁块或第二电磁块对永磁块产生磁斥力，进而改变共振腔的宽度Dy，共振消声效果好，维持室内较为安静的环境。
