具体实施方式
下面结合附图和实施例对本发明进行详细的说明。

所述垫片 2 为非导磁材料, 以免对音圈马达内部的磁场产生影响 。
所述黏胶包括位于所述垫片的通孔***的热固化胶和位于所述热固化胶***的光固化胶,或者优选地,所述黏胶为光热固化两用胶。
实施例 4
如图 4 所示,现有技术中的普通音圈马达,包括底座 31 和设置在所述底座 31 上的载体 32 ,所述载体 32 的外侧缠绕有线圈 33 ,所述载体 32 的上下端分别设置有上弹片 35 和下弹片 34 ,所述上弹片 35 上还设置有上弹片盖 36 ,所述线圈 33 的外侧设有磁性组件(图中未示出),所述磁性组件(图中未示出)的外侧设有磁轭 37 。
实施例 5
如图 5 所示,一种音圈马达的倾角调整方法,包括如下步骤:
步骤 1 :提供实施例 1 中所述的倾角调整座和实施例 2 中所述的垫片 2 ;
步骤 2 :将所述垫片 2 吸附在所述倾角调整座的基座 11 上,所述球形顶杆 12 穿过其通孔;
步骤 3 :在所述垫片 2 的表面涂覆一层黏胶 4 ;
步骤 4 : 将所述球形顶杆 12 调节到合适的高度,并将音圈马达放置在所述球形顶杆 12 的球面上,使音圈马达与黏胶 4 相接触 ;
步骤 5 :调整音圈马达的角度,使音圈马达的光轴垂直于垫片 2 ;
步骤 6 :对所述垫片 2 和音圈马达之间的黏胶 4 进行固化。
音圈马达在组装的过程中都不可避免地存在组装误差,或者各组件设计上的误差,载体 32 并非垂直于底座 31 的,当底座 31 在水平面上放置时,载体 32 的中轴与竖直轴之间存在一个微小的倾角α,导致音圈马达的光轴和竖直轴之间也存在倾角α。本发明将音圈马达放置在所述球形顶杆 12 的球面上,音圈马达可以在球面上作 360 °转动,通过主动给予音圈马达一个角度β,使音圈马达的光轴垂直于垫片 2 ,即载体 32 的中轴与竖直轴重合,其中α=β;纠正完音圈马达的倾角α后,再对音圈马达和垫片 2 之间的黏胶 4 进行固化,从而完成整个调整过程。
其中,步骤 5 包括:
步骤 5.1 :在音圈马达的载体 32 内安装一反射镜 5 ,其反射面面向音圈马达的底部;
步骤 5.2 :在球形顶杆 12 的底部设置准直仪 6 ,准直仪 6 向所述反射镜 5 发射光线,光线经反射镜 5 反射后回到准直仪 6 ;
步骤 5.3 :调整音圈马达的角度,使反射镜 5 的入射光线和反射光线重合。
音圈马达在组装过程中不可避免地其载体 32 会产生倾角α,而且倾角α很小,一般不会超过 30 分,即不到半度;一般情况下,若倾角α超过 20 分就会被当做废品,失去调整的意义,以一个 8.5mm*8.5mm 规格的音圈马达为例,当其载体 32 的倾角α为 20 分时,纠正完后,其底座 31 两端的高度差为 0.05mm ,凭肉眼和显微镜是没有办法辨别的,以现有的技术来说,只能采用准直仪 6 等精准的设备才能检测出来。
如上所述,纠正完音圈马达的倾角α后,其底座 31 两端是具有高度差的,即底座 31 和垫片 2 之间有一个角度β,但是高度差极其微小,由于黏胶 4 在未固化前具有流动性,因此,在调整过程,当底座 31 挤压垫片 2 时,未固化的黏胶 4 足以填满底座 31 和垫片 2 之间的间隙,并弥补底座 31 两端的高度差。
其中,步骤 3 包括:
步骤 3.1 :在所述垫片 2 的通孔***涂覆热固化胶;
步骤 3.2 :在所述热固化胶***涂覆一层光固化胶。
其中,步骤 6 包括:
步骤 6.1 :对所述光固化胶进行光固化;
步骤 6.2 :对所述热固化胶进行热固化。
由于在垫片 2 和底座 31 粘合后,紫外光难以进入垫片 2 和底座 31 之间,所以先对垫片 2 和底座 31 之间的***采用光固化进行定形,再采用热固化对内部进行最后固定。
优选地,步骤 3 中的黏胶为光热固化两用胶,则步骤 6 包括:
步骤 6.1 :对所述光热固化两用胶的***区域进行光固化;
步骤 6.2 :对所述光热固化两用胶的内部区域进行热固化。
优选地,所述垫片 2 为非导磁材料, 以免对音圈马达内部的磁场产生影响 。
实施例 6
一种音圈马达的组装方法,包括如下步骤:
步骤 1 :将音圈马达的各部件组装在一起,形成完整的音圈马达;
其中,该音圈马达为实施例 4 中所述的音圈马达,包括底座 31 和设置在所述底座 31 上的载体 32 ,所述载体 32 的外侧缠绕有线圈 33 ,所述载体 32 的上下端分别设置有上弹片 35 和下弹片 34 ,所述上弹片 35 上还设置有上弹片盖 36 ,所述线圈 33 的外侧设有磁性组件(图中未示出),所述磁性组件(图中未示出)的外侧设有磁轭
步骤 2 :采用实施例 5 中所述的倾角调整方法,对音圈马达的倾角进行调整。
实施例 7
如图 6 所示,一种音圈马达,该音圈马达的底部通过黏胶 4 粘贴有一垫片 2 ,所述垫片 2 具有通孔,该音圈马达的光轴垂直于所述垫片 2 。
所述音圈马达的具体结构包括底座 31 和设置在所述底座 31 上的载体 32 ,所述载体 32 的外侧缠绕有线圈 33 ,所述载体 32 的上下端分别设置有上弹片 35 和下弹片 34 ,所述上弹片 35 上还设置有上弹片盖 36 ,所述线圈 33 的外侧设有磁性组件(图中未示出),所述磁性组件(图中未示出)的外侧设有磁轭。
其中,所述音圈马达和垫片 2 之间有一角度β,即所述底座 31 和垫片 2 之间有一角度β,通过该角度β纠正载体 32 的中轴和竖直轴之间的倾角α,使音圈马达的光轴与竖直轴重合,其中β=α。
所述黏胶 4 包括位于所述垫片 2 的通孔***的热固化胶和位于所述热固化胶***的光固化胶。
在固化过程中,由于在垫片 2 和底座 31 粘合后,紫外光难以进入垫片 2 和底座 31 之间,所以先对垫片 2 和底座 31 之间的***采用光固化进行定形,再采用热固化对内部进行最后固定。
优选地,所述黏胶 4 为光热固化两用胶,先用紫外光对所述光热固化两用胶的***区域进行光固化,再对所述光热固化两用胶的内部区域进行热固化。
所述垫片 2 为非导磁材料,以免对音圈马达内部的磁场产生影响。
以上所述实施例仅表达了本发明的实施方式,其描述较为具体和详细,但并不能因此而理解为对本发明专利范围的限制, 但凡采用等同替换或等效变换的形式所获得的技术方案,均应落在本发明的保护范围之内 。
