Flexible damping sound insulation board based on photonic crystals

The utility model discloses a flexible damping sound insulation board based on phononic crystals, which belongs to the technical field of sound insulation, and comprises a flexible board body and at least two flexible particle layers, the at least two flexible particle layers are arranged in the flexible board body, and the flexible particle layers are arranged in the flexible board body. The flexible particles of each flexible particle layer are periodically arranged, and the particle size of the flexible particles of the lower flexible particle layer is smaller than that of the flexible particles of the upper flexible particle layer. According to the flexible damping sound insulation board based on the phononic crystals, the sound insulation effect can be improved, and the sound insulation effect on sound waves with specific frequencies or specific frequency bands is more prominent. 本实用新型公开了一种基于声子晶体的柔性阻尼隔声板，属于隔声技术领域，一种基于声子晶体的柔性阻尼隔声板，包括柔性板体和至少两层柔性颗粒层，至少两层柔性颗粒层均设置于柔性板体的内部，每层柔性颗粒层的柔性颗粒均呈周期性排列，且位于下层的柔性颗粒层的柔性颗粒的
