随着消费类电子市场的扩大， 大量手机、 笔记本电脑等消费类电 子产品得到广泛应用，作为消费类电子产品中重要的声学部件， 扬声 器模组具有广泛的需求。 随着人们对消费类电子产品要求的提高， 扬 声器模組的性能也越来越受到人们的关注
扬声器模组， 包括壳体， 收容固定于所述壳体内的扬声器单体， 壳体上对应扬声器单体设置有供声音出射的声孔，扬声器单体发出的 声音从声孔传递到扬声器模組外。 为了提高模组防水防尘性能， 同时 调节扬声器模组的声学性能，在声孔位置处通常粘贴有网状物 : 通常 为了便于装配， 上述的网状物使用金属材料制作， 其硬度高， 装配时 便于定位， 但是由于受材料及工艺限制， 金属网比较厚， 而且金属网 的网孔孔径一般比较大， 通常在 imm以上， 不能做的更小， 导致 其防水防尘效果差且易发生锈蚀，对扬声器模组性能造成不利影响 而且金属材料会增大模組的金属区域，对终端产品的部分零部件造成 影响。
上述的网状物也有使用非金属的柔性网，例如使用尼龙材料加工 制成的柔性网， 可以减小厚度以及将网孔做小， 通常将其手工粘贴于 扬声器模组的壳体表面，但是由于材料比较柔软， 进行粘贴时不宜操 作， 装配效率低且易出现不合格件， 并且柔性网易产生毛边， 影响产 品外观· 说 明 书 在組装过程中，通常采用手工粘贴或自动粘贴的方式将阻尼布或 金属网粘贴于声孔位置， 手工粘贴时， 阻尼材料的定位性差、 组装的 效率较低， 自动粘贴則增加了模組的生产成本； 在声孔位置粘贴的阻 尼材料影响产品外观且增加了扬声器模组体积； 因此， 有必要提供一 种改进以克服现有技术杨声器模組、扬声器模组声孔处的网状物及其 装配方法的缺陷。 发明内容

本发明扬声器模组的非金属网状遮挡件，设置在出声孔位置处与 壳体一体注塑而成的， 有效调节扬声器模組声学性能的同时， 不对扬 声器模組体积造成影响， 提高扬声器.模组内部空间利用率； 遮挡件与 壳体一体注塑而成结合牢固度高， 避免遮挡件脱落， 提高了扬声器模 组的可靠性， 非金属遮挡件可以与非金属壳体一体注塑而成， 减少了 模组的金属区域， 同时在生产过程中不必粘贴其他部件， 提高了生产 效率。 因此， 本发明扬声器模组声孔处遮挡件具有声学性能好， 可靠 性高， 空间利用率好， 生产效率高的优点
本发明还提供了一种扬声器模組声孔处遮挡件的装配方法，包括 下述步骤：
(1 ) 制作基板， 在基板上排列有若千个镂空孔；
(2) 制作非金属的柔性网料带， 然后将柔性网料带粘贴到基板 上并覆盖住所有镂空孔；
(3) 将粘贴有柔性网料带的基板放置于第一注塑模具中， 然后 在每个镂空孔对应的柔性网料带上注塑形成与柔性网料带结合在一 起的环形的第一注塑体；
(4) 对第一注塑体周边的柔性网料带进行栽切， 获得独立的笫 一注塑件，所述笫一注塑件包括结合在一起的第一注塑体和对柔性网 料带进行裁切形成的所述遮挡件；
(5) 将第一注塑件放置于第二注塑模具中， 然后进行第二次注 塑形成结合有第一注塑件的扬声器模组的壳体，笫一注塑体的内孔作 为扬声器模组的声孔。
其中， 在步骤 （2) 与步骤 （3) 之间， 在基板上柔性网料带的两 说 明 书 侧开设定位孔，然后通过定位孔将粘贴有柔性网料带的基板固定于第 一注塑模具中。
其中， 在步骤 （2) 与步驟 （3) 之间， 在每个镂空孔对应的柔性 网料带的两侧进行去料形成两个去料孔，两个去料孔之间形成一个柔 性网跨梁， 笫一注塑体形成于所述柔性网跨梁上， 柔性网跨梁的长度 大于笫一注塑体的长度， 且宽度方向上完全覆盖住第一注塑体的内 孔。
作为一种优选的技术方案，所述柔性网跨梁的宽度略小于笫一注 塑体两侧外边缘之间的宽度，所述柔性网跨梁的两側边缘在笫一注塑 体成型过程中嵌进第一注塑体中。
作为一种优选的技术方案， 在步骤 （5) 中, 第一注塑件在第二 次注塑过程中形成为扬声器模組壳体内壁的一部分，笫一注塑件中的 遮挡件夹设于扬声器模組壳体内或者是棵露于扬声器模组壳体的内 表面。

本发明装配方法中的基板为长条形，在每个基板上排列有若千个 镂空孔，在后续步骤中每个镂空孔处对应加工出一个第一注塑件， 因 此，可以一次成型多个第一注 ¾件，提高了生产效率。笫一次注塑后， 在每个镂空孔对应的柔性网料带上注塑形成结合在一起的环形的笫 —注塑体， 对周边柔性网料带进行裁切后获得独立的第一注塑件， 通 过第一注塑体实现了对柔性网的周边定位， 解决了柔性网由于比较 软、 易变形， 不易进行装配的问题； 然后通过第二次注塑形成结合有 第一注 ¾件的扬声器模組的壳体，第一注塑体的内孔便作为了扬声器 模组的声孔， 至此便实现了柔性网的装配。 上述装配方法， 使得遮挡 说 明 书 件的装配操作简单易实现， 提高 τ装配效率， 而且通过注塑工艺实现 柔性网的装配， 结合牢固度髙， 避免了现有技术中柔性网粘接不牢易 容易脱落的问题。
进一步的， 可以在笫一次注塑前， 对每个镂空孔对应的柔性网料 带的两侧进行去料， 这祥单纯的对平面的柔性网料带进行操作， 相对 于第一注 ¾体成型后再对其两侧进行裁切， 更加容易实现；在中间形 成的柔性网跨梁上注塑成型第一注塑体后，只要将笫一注塑体两端的 比较窄的柔性网料带连接处切断即可， 降低了裁切难度， 提高了裁切 效率。
进一步的，使柔性网跨梁的宽度略小于第一注塑体两侧外边缘之 间的宽度，可以使得柔性网跨梁的两側边缘在笫一注塑体成型过程中 嵌进第一注塑体中，通过上述步骤，笫一注塑件的两侧不会产生毛边， 不仅可以保证结合的牢固度， 而且可以使产品外观整齐美观。
此外，本发明的装配方法中由于采用的是非金属的柔性网制成的 遮挡件， 例如可以采用尼龙网料带， 因此可以做的更薄， 厚度可以在
0.05η Ή左右， 能够减小占用空间， 不会增大产品体积； 且其网孔的 孔径可以做的非常小， 能够达到（),03〜 05mm， 可以提髙扬声器模组 的防水防尘性能， 且不会发生锈蚀， 提高扬声器模组的使用寿命和可 靠性。

本发明还介绍了扬声器模组声孔处遮档件的装配方法， 如图 6- 图 8所示， 以如下实施例一和二为例进行说明。
实旄例一
如图 6所示， 一种扬声器模组声孔处遮挡件的装配方法， 其中， 本实施例使用的遮挡件采用尼龙网， 可以节省成本， 当然也可以是其 它公知的¾料网，其厚度选择为 0.05〜0.3mm，网孔孔径选择为 0,0；？〜' 0.1mm ,进一步的，为了达到更佳效果 ,厚度可以控制在 0.05〜0.1mm， 具体厚度可以采用 0.05mm， 网孔孔径可以控制在 0.03〜0.05mm。 相 对于使用金属网， 遮挡件可以做的更薄， 能够减小占用空间， 不会增 大产品体积； 且其网孔的孔径可以做的非常小， 可以提高扬声器模组 的防水防尘性能， 且不会发生锈蝕 ,提高扬声器模組的使用寿命和可 靠性。
本发明中的装配方法， 具体包括下迷步骤：
( 1 ) 制作基板 5 , 为了节省成本， 基板 5具体采用 PET材料制 作， 当然， 还可以采用其它的非金属或金属材料制作均可。 将基板 5 制作为长条形，在基板 5上排列有若干个镂空孔 11 ,在后续步骤中每 个镂空孔 11 处对应加工出一个笫一注塑件 7 , 因此， 本发明的装配方 法， 可以一次成型多个笫一注塑件 7 , 提高了生产效率。
(2)制作非金属的柔性网料带 6，然后将柔性网料带 6粘贴到基 说 明 书 板 5上并覆盖住所有镂空孔 1 1。为了在后续步驟中实现可靠定位，在 基板 5上柔性网料带 6的两侧开设定位孔 13。
( 3) 将粘贴有柔性网料带 6的基板 5放置于第一注塑模具中， 通过定位孔 13将粘贴有柔性网料带 6的基板 5进行固定, 然后在每 个镂空孔 11对应的柔性网料带 6上注塑形成与柔性网料带 6结合在 —起的环形的第一注¾体31 , 笫一注塑体 31 内孔的大小等于或略大 于预设的声孔大小。
(4) 对笫一注塑体 31周边的柔性网料带 6进行裁切， 获得若千 个独立的第一注塑件 7， 该笫一注塑件 7包括结合在一起的笫一注塑 体 31和对柔性网料带 6进行裁切形成的遮挡件 4。 通过第一注塑体 31实现了对遮挡件 4的周边定位， 解决了遮挡件 4由于比较软、 易变 形， 不易进行装配的问题。
( 5) 将笫一注塑件 7放置于笫二注塑模具中， 然后进行第二次 注塑形成结合有第一注塑件 7的扬声器模組的壳体 1， 笫一注塑体 31 的内孔即作为扬声器模组的声孔， 至此便实现了遮挡件 4的装配。 本 实施例中， 第一注塑件 7形成为扬声器模組壳体 1 内壁的一部分， 第 一注塑件 7中的遮挡件 4夹设于扬声器模组壳体 1 内 , 当然， 也可以 使遮挡件 4棵露于扬声器模组壳体 1的内表面。不局限于上述装配工 艺，也可以是将第一注塑件 7形成为扬声器模组壳体 1外壁的一部分 , 第一注塑件 7中的遮抟件 4夹设于扬声器模組壳体 1内或者是棵露于 扬声器模組壳体〗 的外表面。
上述装配方法， 使得遮挡件 4的装配操作筒单易实现，提高了装 配效率， 而且通过注塑工艺实现遮挡件 4的装配， 结合牢固度高， 避 免了现有技术中遮抟件 4粘接不牢易容易脱落的问题。
实旄例二
该实施例与实施例一的不同之处在于： 在上述的步骤 （2) 与步 骤 （3) 之间， 在每个镂空孔 11对应的柔性网料带 6的两側进行去料 说 明 书
形成两个去料孔 21， 两个去料孔 21之间形成一个柔性网跨梁 22。 步 骤 （3) 中， 第一注塑体 31形成于该柔性网跨梁 22上， 柔性网跨梁 22的长度大于笫一注塑体 31的长度， 且宽度方向上完全覆盖住第一 注塑体 31 的内孔。 上述步骤， 在第一次注塑前， 先对每个镂空孔 11 对应的柔性网料带 6的两侧进行去料，这样单纯的对平面的柔性网料 带 6进行操作 , 相对于笫一注 ¾体 31成型后再对其两侧进行裁切， 更加容易实现； 在中间形成的柔性网跨梁 22上注塑成型第一注塑体 31后， 只要将笫一注塑体 31两端的比较窄的柔性网料带 6连接处切 断即可， 降低了裁切难度， 提高了裁切效率。
此外， 上述步骤中， 使柔性网跨梁 22的宽度略小于第一注塑体 31两侧外边缘之间的宽度， 柔性网跨梁 22的两侧边缘在第一注塑体 31成¾过程中嵌进第一注塑体 31 中。 通过该步骤， 第一注塑件 7的 两侧不会产生毛边， 不仅可以保证结合的牢固度， 而且可以使产品外 观整齐美现。
以上仅为本发明实旄案例而已， 并不用于限制本发明，但凡本领 域普通技术人员根据本发明所揭示内容所作的等效修饰或变化，皆应 纳入权利要求书中记载的保护范围内。
