一种声子晶体隔音结构和板状结构
摘要：
本实用新型公开了一种声子晶体隔音结构和板状结构。所述声子晶体隔音结构包括：隔音层，所述隔音层包括多个隔音介质，所述隔音介质包括核心以及包覆所述核心的包覆层，所述核心的弹性模量大于包覆层的弹性模量，且所述核心的密度大于所述包覆层的密度。本实用新型所述的声子晶体隔音结构有效的降低了噪音的传播，提高了吸收噪音的效果。
摘要（英）：

The utility model discloses a phonon crystal sound -insulating structure and platelike structure. The phonon crystal sound -insulating structure include: the puigging, the puigging includes a plurality of syllable -dividing media, the medium that gives sound insulation includes core and cladding the coating of core, the elastic modulus of core is greater than the elastic modulus of coating, just the density of core is greater than the density of coating. The effectual propagation that reduces the noise of phonon crystal sound -insulating structure, improved noise absorbing's effect.
