The present invention relates to a composite structure for sound insulation suitable for broadband frequencies and a multi-composite sheet comprising the same. The composite structure may include a first sheet layer including first hexagonal units forming a hexagonal pattern, an elastic film layer laminated on the first sheet layer and including a polymer, and a second sheet layer including second hexagonal units forming a hexagonal pattern. The second sheet layer is laminated on the elastic film layer and includes second hexagonal units forming a hexagonal pattern. The first hexagonal unit has a center, and the point where the vertexes of the plurality of second hexagonal units are connected is located in the center.

    本发明涉及适用于宽带频率的用于隔音的复合结构和包括其的多重复合片。所述复合结构可以包括第一片层、弹性膜层和第二片层,所述第一片层包括形成六边形图案的第一六边形单元,所述弹性膜层层压在所述第一片层上并且包括聚合物,所述第二片层层压在所述弹性膜层上并且包括形成六边形图案的第二六边形单元。所述第一六边形单元具有中心,多个第二六边形单元的顶点连接的点位于所述中心。
