Screen and sound insulation structure

The utility model provides a screen and a sound insulation structure. The screen comprises a screen core, at least part of the screen core is provided with at least one super-structure sound insulation unit, and each super-structure sound insulation unit is provided with at least one super-structure sound absorption unit; wherein the super-structure sound absorption unit is provided with a plurality of resonant cavities, and the plurality of resonant cavities are configured to absorb incident sound waves in a preset frequency band through resonance. According to the screen, the acoustic metamaterial is combined with the screen core part, and broadband efficient sound insulation under the sub-wavelength scale can be achieved. 本申请提供一种屏风及隔声结构。该屏风包括屏芯，其中，至少部分屏芯具有至少一个超构隔声单元，超构隔声单元具有至少一个超构吸声单元；其中，超构吸声单元具有多个谐振腔，多个谐振腔被配置为通过共振吸收预设频段下的入射声波。该屏风通过将声学超构材料与屏芯部分相结合，有利于实现亚波长尺度下的宽带高效隔声。
