The purpose of the installation is to make the voice coil motor after the assembly is completed, and it is not trapped in the positioning device of the base due to the attraction of the magnet.

定位腳和定位孔之設置可互換的，即，底座500具有定位腳而蓋體600具有定位孔。定位腳和定位孔之數量和形狀也不限於實施例所示，可根據實際需要設計。The arrangement of the positioning foot and the positioning hole is interchangeable, that is, the base 500 has a positioning leg and the cover 600 has a positioning hole. The number and shape of the positioning legs and the positioning holes are not limited to those shown in the embodiment, and can be designed according to actual needs.

底座500和蓋體600之磁鐵槽可為一個、三個或其他數目，其形狀大小均根據實際需要設計。The magnet slots of the base 500 and the cover 600 may be one, three or other numbers, and the shapes and sizes are designed according to actual needs.

另外，支撐柱之數量也可根據實際情況省略或設兩個、四個。In addition, the number of support columns can also be omitted or set two or four according to actual conditions.

請參看圖3，本發明第二實施例提供之底座700與第一實施例提供之底座500大致相同，其不同之處在於：底座腳704具有一朝向本體中心之側表面7041，該側表面7041上設有定位結構703。Referring to FIG. 3 , the base 700 provided by the second embodiment of the present invention is substantially the same as the base 500 provided by the first embodiment, except that the base leg 704 has a side surface 7041 facing the center of the body, and the side surface 7041 . A positioning structure 703 is provided thereon.

定位結構703為一凹入底座腳704側面7041之直角凹槽，該直角凹槽朝向本體50中心。於實際生產中，該直角 處並不是標準直角，而為一倒圓角。The positioning structure 703 is a right angle groove recessed into the side 7041 of the base leg 704, the right angle groove being toward the center of the body 50. In actual production, the right angle It is not a standard right angle, but a rounded corner.

相對應地，本實施例提供之蓋體800之定位結構之設置與底座700之定位結構設置一致。Correspondingly, the positioning structure of the cover 800 provided in this embodiment is consistent with the positioning structure of the base 700.

以下，以本發明第一實施例為例具體地說明音圈馬達之組裝步驟。Hereinafter, the assembly procedure of the voice coil motor will be specifically described by taking the first embodiment of the present invention as an example.
