Sound insulation glass with adjustable sound absorption frequency band and sound insulation method
The invention discloses sound insulation glass with the adjustable sound absorption frequency band. The sound insulation glass comprises a cavity layer, and a hole layer and an adjusting layer are arranged on the two sides of the cavity layer correspondingly; through holes are formed in the cavity layer in an array mode, neck holes corresponding to the through holes one to one are formed in the hole layer, and adjusting blocks corresponding to the through holes one to one are arranged on the adjusting layer; the adjusting blocks are in sliding fit with the corresponding through holes, volume-adjustable sound absorption cavities are formed among the adjusting blocks, the through holes and the hole layer, and the neck holes are in communication with the corresponding sound absorption cavities to form a Helmholtz resonance structure; and the sound insulation glass further comprises a sound absorption frequency band adjusting mechanism used for driving the adjusting layer to move relative to the cavity layer so as to adjust the volume of the sound absorption cavities. The invention further discloses a sound insulation method adopting the sound insulation glass with the adjustable sound absorption frequency band. According to the sound insulation glass with the adjustable sound absorption frequency band and the sound insulation method, the Helmholtz resonator principle is utilized, the sound absorption frequency can be adjusted in a stepless mode to be matched with different noise, and therefore the better sound absorption and noise reduction effect is achieved.
本发明公开了一种吸声频段可调的隔音玻璃，包括腔体层，所述腔体层的两侧分别设有孔洞层和调节层；所述腔体层上阵列设有通孔，所述孔洞层上与所述通孔一一对应设有颈孔，所述调节层上与所述通孔一一对应设有调节块；所述调节块与对应的所述通孔之间滑动配合，所述调节块、通孔和所述孔洞层之间构成体积可调节的吸声腔，所述颈孔与对应的所述吸声腔相连通并构成亥姆霍兹共振结构；还包括用于驱动所述调节层相对于所述腔体层移动进而调节所述吸声腔的体积的吸声频段调节机构。本发明还公开了一种采用如上所述吸声频段可调的隔音玻璃的隔音方法。本发明利用亥姆霍兹共振器原理，可无级调节吸声频率以匹配不同的噪音，从而达到更好的吸声降噪效果。
