背景技术
随着通讯设备在户外严酷环境下的特殊需求，通讯设备受话器需要设置防 尘防水网 （也称防护薄膜）。
参见图 1 , 该图为现有通讯设备受话器的防尘防水网的结构图。 现有通讯 设备受话器的防尘防水网（也称防护薄膜） 103通过胶粘剂 102背附在片材 101 上， 再通过胶粘剂 104与受话器（图中未示出）连接， 这样就使得通讯设备受 话器声音的音量低、 音质差。
另外，在强冲水的防护级别要求下，现有通讯设备受话器的防尘防水网很 容易被水压冲破， 使通讯设备（例如受话器件）表面进水， 对声音及相关可靠 性均带来严重影响。
随着通讯设备在户外严酷环境下的特殊需求，如何在保证高标准的防尘防 水防护级别前提下， 同时要求输出良好的音质效果，是本领域技术人员需要解 决的技术问题。

具体实施方式
本发明提供一种电声器件的防尘防水网，用于保证高标准的防尘防水防护 级别前提下， 同时要求输出良好的音质效果。 为了更清楚地说明本发明的电声器件的防尘防水网的具体结构，下面结合 附图具体说明。
参见图 2至图 5 , 图 2是本发明第一实施例所述电声器件的防尘防水网俯 视图； 图 3是图 2所示 A-A向剖视图； 图 4是本发明第一实施例所述电声器 件的防尘防水网仰视图；图 5是本发明第一实施例所述电声器件的防尘防水网 的***图。
本发明第一实施例所述电声器件的防尘防水网， 包括防护薄膜组件 1。 所 述防护薄膜组件 1具体可以包括网布 17、与所述网布 17相粘接的无孔片材 15、 与所述无孔片材 15相粘接的薄膜 13 , 以及与所述薄膜 13相粘接的泡棉 11。 所述电声器件具体可以为受话器件、 麦克风、 蜂鸣器等。
所述泡棉 11具体可以为弹性泡棉， 用于起密封的作用。
所述薄膜 13可以为微孔薄膜，例如 E-PTFE(聚四氟乙烯）薄膜等。 E-PTFE 薄膜具有防水透气透声作用。无孔径片材 15不仅起到对薄膜 13进行制作、模 切时加强作用外，还起到对薄膜 13与网布 17之间保持的隔离空间的作用， 能 够保证薄膜 13在受话器产生气流时的振动空间。 网布 17起到对薄膜 13进行 限幅， 保证水压过大时， 薄膜 13不超过其形变最大幅度的作用。 同时， 网布 17需要具有良好的透声性， 表面光洁， 无毛丝， 以免破坏薄膜 13。 所述网布 为微孔网布。 网布 17的丝孔目数可以为 100目 -500目， 最佳在 200目到 300 目左右。
所述薄膜 13的厚度为 0.01-0.035mm。薄膜 13最佳厚度范围为 0.02-0.03mm 之间， 薄膜 13具有防水性、 透气性良好。 薄膜 13对声音的衰减能在 3dB以 内， 在特殊要求时， 可以增加防油特性。 薄膜 13在制作加工时， 薄膜 13不可 受拉， 平整的平铺在带有基材的胶粘剂上。 薄膜 13成型后， 成品薄膜表面不 可受损， 表面无灰尘、 油污等， 同时注意封装与保存。
所述网布 17通过可以第一粘贴剂 18与电声器件 3相粘接。 第一粘贴剂 18用于保证防护薄膜组件 1装配到受话器壳体上后， 构件整体的防水效果。
所述第一粘贴剂 18具体可以为带基材的双面防水胶粘剂。 所述第一粘贴 剂 18优选具有良好的防水特性。 当电声器件为低表面能的材料表面时， 选择 第一粘贴剂 18需要具有良好的胶贴性， 以保证电声器件 3的防护可靠及使用 寿命。
根据本发明实施例所述电声器件的防尘防水网结构设计安装需要，可以在 泡棉 11表面上设置第一粘贴剂 18即双面防水胶粘剂 （通过第一粘贴剂 18与 电声器件的面壳内表面粘贴）， 也可以在网布 17表面上放置第一粘贴剂 18即 双面防水胶粘剂（通过第一粘贴剂 18与电声器件的面壳外表面粘贴）。此两种 情况对防尘防水网的性能与可靠性没有影响。
所述网布 17与所述无孔片材 15具体可以通过第三粘接剂 16相粘接。 所 述无孔片材 15与所述薄膜 13具体可以通过第四粘接剂 14相粘接。 所述薄膜 与 14所述泡棉 11具体可以通过第五粘接剂 12相粘接。
所述第三粘接剂 16、第四粘接剂 14、第五粘接剂 12可以为相同的粘接剂， 具体可以为带基材的双面胶粘剂。要求带基材的双面胶粘剂对泡绵、 网布类及 塑胶具有良好的胶粘性，厚度薄。 带基材的双面胶粘剂具体可以是丙稀酸类胶 粘剂， 可以提高微孔的密封性。 另外带基材的双面胶粘剂还需要具有良好的抗 湿性， 避免薄膜因湿气浸透而脱落。
本发明所述电声器件的防尘防水网， 由于薄膜 13位于所述网布 17上方， 可有效地防止水进入到薄膜 13与网布 17的夹层中，保证了电声器件声音的音 质。 另外由于在薄膜 13外粘接了泡棉 11 , 在提高防水可靠性的同时也提升声 音音质， 能够为薄膜 13的吸震与密封提供技术保障。
防护薄膜组件 1的厚度尺寸及构件尺寸依产品结构设计需要来控制决定。 在制作防护薄膜组件 1时， 需要对泡绵 11的透声孔位与各胶粘剂（第一、 三、 四、 五胶粘剂）、 无孔片材 15的对应开孔同心偏差作要求。
在满足结构设计和装配需要时，本发明实施例所述电声器件的防尘防水网 可以包括两个或多个构件组成， 实现灵活装配。
为了进一步保证防水和音质的效果，本发明第二实施例所述电声器件的防 尘防水网相对第一实施例的区别在于增加了防护网组件 2。
参见图 6, 该图是本发明第二实施例所述电声器件的防尘防水网的*** 图。
本发明第二实施例所述电声器件的防尘防水网还包括与所述防护薄膜组 件 1相粘接的防护网组件 2。 为了具体便于本领域技术人员对于防护网组件 2结构得了解，下面结合图 7至图 10具体说明。
参见图 7至图 10, 图 7是本发明实施例所述防护网组件俯视图； 图 8是 图 7所示 B-B向剖视图； 图 9是本发明实施例所述防护网组件仰视图； 图 10 是本发明实施例所述防护网组件的***图。
本发明实施例所述防护网组件 2与防护薄膜组件 1 为相互分离的两个部 件， 既可以装配在一起， 也可以将防护网组件 2外装于壳体。 依具体结构和产 品不同可选择不同的装配方式， 因此应用更加灵活。
防护网组件 2能在强冲水条件下保证电声器件声音的音质。本发明第二实 施例所述电声器件的防尘防水网在环境不洁净， 冲水中混有泥沙， 也不会对防 水与音质产生严重的影响， 能够满足更高的可靠性要求。
所述防护网组件 2具体包括带孔径片材 21 , 带孔径片材 21通过第二粘接 剂 22与所述防护薄膜组件 1的泡棉 11或所述电声器件 3的外壳相粘接。
所述防护网组件 2的带孔径片材 21的表面需要***刺。 带孔径片材 21 的主要作用是分减冲水水压， 保护薄膜 13免受太大水压从而防止薄膜 13 破裂。
经验证， 防护薄膜组件 1可以达到 IP67潜水防护级别， 而防护薄膜组件 1上表面再增贴防护网组件 2, 可以达到 IP66强冲水防护级别。
防护薄膜组件 1及防护网组件 2的厚度尺寸及构件尺寸依产品结构设计需 要来控制决定。
另外，防护薄膜组件 1及防护网组件 2的形状可根据设计需要设计为方形、 圆形或其他形状。
以上防护薄膜组件 1及防护网组件 2中的片材、网布以及胶粘剂不是唯一 的选择材料， 只要满足其功能与性能要求均可。
对所公开的本发明实施例所述电声器件的防尘防水网的上述说明，使本领 域专业技术人员能够实现或使用本发明。对这些实施例的多种修改，对本领域 的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离 本发明的精神或范围的情况下， 在其它实施例中实现。 因此， 本发明将不会被 限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相 一致的最宽的范围。
以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发 明的精神和原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发 明的保护范围之内。
