技术领域
本发明涉及一种隔音垫，具体涉及一种汽车门板隔音垫。
背景技术
汽车门板内侧通常设有防水隔音垫，采用的防水隔音垫需要具备吸音、隔音隔热和防水三种功能，隔音隔热需要一层阻尼的材料保证车外部轮胎摩擦的声音、空气流动的声音等其他噪音或振动的声音不进入到驾驶室影响乘客，吸音则需要开孔性的材料以有效的吸收各种传递过来的声音，防水则需要使用特殊的材料阻止从玻璃上或者车身上流到门板内的水避免门板内的玻璃升降器和扬声器等电器部件受潮短路。现有的隔音垫均通过几种材料简单叠加而成，其防水能力堪忧。
有鉴于上述的缺陷，本设计人，积极加以研究创新，以期创设一种新型结构的汽车门板隔音垫，使其更具有产业上的利用价值。
