在本实施例中，该控制模块还包括与声学纹理铝合金框连接的声学减震安装配件8(由四个安装拉铆螺母作为减振器点位安装)，声学减震安装配件8安装于第二防尘透声网布层6(后导腔)侧，有效提高整体安全系数。
在本实施例中，面板层1由高密度纤维板(硬度75-80)穿孔制成，穿孔率为20％-30％，厚度为8mm。通过编程二维穿孔图谱，由高速激光穿孔加工成型，加边框作为外观装饰及功能使用。在其它示例中，面板层1也可采用其它硬质材料，如复合材料、木板等，对木板等材料进行不规则计算二维穿孔。
在本实施例中，第一防尘透声网布层2、第二防尘透声网布层6采用厚度为1.0mm穿孔透声网布，透声量为75％-80％。第一防尘透声网布层2结合面板层1可达到吸声和慢扩散的效果。(后导腔)第二防尘透声网布层6能够有效防止颗粒粉尘堵塞影响低频吸音系数，提高低频吸音，稳定材料在空气和湿度分离。

在本实施例中，复合阻尼分隔层4由复合橡塑阻尼、金属铁粉及纤维制成，作为分隔层，厚度为1.2mm-2.0mm。复合阻尼分隔层4作为频段声学流阻分割防止前后声音互相穿透，有效解决声学振动问题，增强声音弹性，重为3kg/m2-5kg/m2。
在本实施例中，各层通过多点进行胶合连接形成一个整体，避免产生机械震动噪音，各层均具备一定的支撑稳定作用，该整体与边框过盈配合且使用高性能免钉胶进行连接封装构成本实例，各层相辅相成共同作用决定了本实例的声学性能。
经过检测，该全频声学控制模块，降噪系数NRC＝0.85，依据GB/T16731-1997《建筑吸声产品的吸声性能分级》判定，其吸声构造的吸声性能为Ι级。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。
