背景技术
激光电视技术进步，已研发出发声屏幕，屏幕可直接作为发声单元。其结构为玻纤蒙皮与铝蜂窝芯构成的夹心板，贴附在玻纤蒙皮上的激励器使玻纤蒙皮震动，通过蜂窝芯材的空腔产生声音。作为主要的发声和显像单元，制造发声背板的技术要求很高。
目前市场上主要是使用玻纤预浸料和热压罐的工艺来生产发声背板。玻纤预浸料生产工艺复杂，制造成本高。热压罐工艺所需设备造价昂贵，模具使用寿命短，生产过程能耗较高。由此导致此工艺生产的发声背板成本很高，严重影响了发声板的市场接受度，制约了激光电视发声屏幕的发展。

在透气隔离膜上铺放玻纤布；
b） 在玻纤布上均匀涂布混合均匀的环氧树脂（树脂与固化剂比例2:1）；
c）将拉伸好的铝蜂窝芯铺放到涂好树脂的玻纤布上；
d）将一张玻纤布涂好树脂，并将其平整的铺叠到蜂窝芯上；
e）上层辅助材料的铺叠：
在玻纤布上方铺设脱模布；
在脱模布上方铺设透气隔离膜；
将表面平整无瑕疵的铝板作为成型模板铺放到透气隔离膜上方；
f）用真空袋膜将铺叠好的材料完全覆盖，真空袋膜边缘使用双面密封胶带与真空作业平台粘结，检查气密性并启动真空泵开始抽真空；
g）真空负压达到0.08MPa时开始保压，6小时后可取出工件；
h）从产品上移除辅助材料，裁切成所需尺寸规格，完成包装出货。
在一些实施方式中，真空作业平台与底层辅助材料之间填充有双面胶。
一种激光电视机发声背板，其创新点在于：包括依次设置的真空袋膜层、第一铝板层、第一透气隔离膜层、第一脱模布层、玻纤布层、第二脱模布层、第二透气隔离膜层以及第二铝板层。
本发明的有益效果是：操作技术要求不高，材料简单，容易操作；使用铝板作为模板适应性强，可以满足多种尺寸规格的要求，且回收利用价值高；使用真空负压工艺及透气隔离膜，可以使树脂均匀地渗透到玻纤布中，提高产品的强度；使用真空负压工艺及透气隔离膜，可以使树脂在玻纤布表面形成一层均匀的胶膜，得到很好的表面质量；该操作方法设备投入较少，生产能耗低，有效地降低了制造成本；辅材的选择搭配科学合理，操作简便，解决了当前激光电视发声背板制造工艺中设备投入大，操作技能要求高，生产能耗大的难点，适用于任何规格的激光电视发声背板的制造。
