Sound insulation and vibration reduction structure
The invention belongs to the technical field of noise control, and discloses a sound insulation and vibration reduction structure. The sound insulation and vibration reduction structure comprises a sound insulation unit, the sound insulation unit comprises a sound insulation plate, a first mass block and a plurality of second mass blocks, the sound insulation plate comprises a sound insulation plate body and a frame connected to the periphery of the sound insulation plate body, the sound insulation plate body and the frame form a containing cavity used for containing noise, the sound insulation plate body is elastic, the first mass block and the second mass blocks are connected to the sound insulation plate body, and the second mass blocks are arranged at intervals and evenly distributed on the periphery of the first mass block. According to the sound insulation and vibration reduction structure, a working frequency band can be widened, sound insulation and vibration reduction within the broadband range can be achieved, the initial working frequency can be reduced, the structure is simple, and the application range is wide.
本发明属于噪声控制技术领域，公开了一种隔声减振结构，该隔声减振结构包括隔声单元，隔声单元包括隔声板、第一质量块和多个第二质量块，隔声板包括隔声板本体和连接于隔声板本体四周的框架，隔声板本体和框架形成用于收容噪声的容纳腔，隔声板本体具有弹性，第一质量块和多个第二质量块均连接于隔声板本体，多个第二质量块间隔设置且均布于第一质量块四周。本发明提供的隔声减振结构可拓宽工作频带，可实现在宽频范围内隔声减振，可降低初始工作频率，结构简单，适用范围广。
