背景技术
在日常家居生活、KTV、歌房等场所，噪音是很常见的，这时候隔音墙就很重要，竹木纤维板是一种环保型建筑材料，隔音效果好，相比纯木墙面，竹木纤维板安装更加便利，但如果仅适用竹木纤维板，隔音效果不太理想，也有一些使用竹木纤维板内加隔音棉，但是隔音棉只能吸音，不能减少声波震动，所以隔音效果也不是特别好，而因此需要增加减震层来减少声波震动，从而提高隔音效果，吸音效果很好的材料很少且成本高，因此可以采用传导声波的方式来隔音，能有效降低成本并且隔音效果好。
发明内容

优选的，所述声波传导管内壁设有吸音涂层，吸收传导的声波。
进一步优选的，所述传导管与传导管之间的空隙中设有吸音棉，吸收传导管透出的噪音。

具体实施方式
下面结合附图与实施例对本发明作进一步详细描述。
如图1所示，包括竹木纤维板主体11，所述竹木纤维板主体11内设有隔音层4、减振层3、传导层，所述隔音层4设于竹木纤维板内中心位置，所述减振层3、传导层以隔音层4为中心依次向外对称分布，传导层将声波传导出去，减振层3用于减少声波机械振动，隔音层4最后隔离残余噪音，对称分布也能增强稳定性，能够降低声波震动，所述竹木纤维板两面开设有若干安装孔12，所述安装孔12内均设有收音管24，所述收音管24一端设有收音装置，所述收音管24另一端与传导层连接，收音装置增强收音效果，通过收音管24将噪音传导至传导层。
如图1、图2所示，所述传导层包括若干个均匀分布的声波折射板25、声波传导管26，所述声波折射板25与收音管24连接，所述声波传导管26与声波折射板25连接，所述声波传导管26沿声波传导方向贯穿竹木纤维板主体11，由收音管24接受的声波通过声波折射板25折射至传导管，再由传导管排出至地底或者隔音处。
如图1、图2所示，所述声波传导管26内壁设有吸音涂层27，吸收传导的声波。
如图1、图2所示，所述传导管与传导管之间的空隙中设有吸音棉22，吸收传导管透出的噪音。
如图1、图2所示，所述收音管24内壁设有声波反射涂层23，将收纳的音波通过反射集中传导至传导层。
如图2所示，所述声波折射板25与收音管24、声波传导管26之间连接角度为135°，使音波折射更有规律。
如图1、图2所示，所述收音装置为收音喇叭21，成本低收音效果好。
如图2所示，所述隔音层4材料为隔音棉，令隔音层4厚度为h，竹木纤维板主体11厚度为H，所述隔音层4厚度范围为

如图1所示，所述竹木纤维板主体11与竹木纤维板主体11之间连接方式为卡槽连接，连接方式简单、易拆卸。
工作原理：如图3所示，声波由收音喇叭21收音至收音管24，收音管24内壁的声波反射涂层23使声波集中传导至声波折射板25，声波折射板25将声波折射至声波传导管26，大部分声波被传导出去降噪，其中一部分被声波传导管26内壁的吸音涂层27吸收，一部分渗透出去被声波传导管26之间间隙中的吸音棉22吸收，之后减振层3的蜂巢结构降低声波的振动，最后残余的声波被厚隔音棉隔音。
以上内容仅为本发明的较佳实施例，对于本领域的普通技术人员，依据本发明专利的思想，在具体实施方式及应用范围上均会有改变之处，本说明书内容不应理解为对本发明的限制。
