如图5所示，所述壳体2为第二方形结构件，所述壳体2的顶面在四个角部位置朝向所述电路板的方向沉降形成台阶f，可起到预压作用，所述顶面为与所述电路板相对的面。图5中，镜头1外侧与壳体2开孔侧壁e采用胶水密封组装，可将外界与壳体2内部封闭，外界的灰尘、异物等无法进入壳体2内部，起到防尘作用。如图10所示，壳体2一侧面为卡爪形，便于固定电路板的出线端。
壳体2可设计成长方形，可减小壳体2外形尺寸，为摄像模组及整机设 计节约空间。
图8所示，包括依次由成像芯片13、第一电路板8、第二电路板9和钢板组成的电性部分，图9所示包括由弹性件3、载体6、线圈、滤光片7与电性部分组装成的动子部分，图10所示包括镜头1和壳体2，镜头1、壳体2和第二磁性组件组成的定子部分。
以下对本申请实施例提供的摄像模组进行详细说明。如图1、图2所示，镜头1与壳体2密封固定组装，两个磁石对称设置在壳体2内壁，线圈(即第一磁组件5)与载体6固定组装，滤光片7组装在载体6底部，第一电路板8与成像芯片13组装后，再整体组装在第二电路板9上。
镜头1：起成像作用；
壳体2：起保护和防尘的作用，保证模组内部与外界环境隔离；
弹性件3：起导向作用，支撑载体6保持平稳运动；
磁石和线圈：线圈通电后与磁石产生电磁力，推动载体6运动；
载体6：下连接电路板，上连接线圈，运动时带动成像芯片13一起运动；
滤光片7：增加可见光入摄，降低其他非可见光，提升拍照画面质量；
成像芯片13：将光信号转化为电信号；
第一电路板8：硬质电路板，连接芯片和第二电路板9，起导通和中间桥梁的作用；
第二电路板9：软质电路板，可接收第一电路板8传递过来的电信号，且可与第一电路板8在线圈导通的状态下，跟随载体6运动；
钢片10：起到支撑和补强的作用；
感应磁铁11：发出磁场；
霍尔芯片12：检测磁场变化，从而确定成像芯片13的位置。
本申请提供的上述摄像模组具有如下有益效果：
通过镜头1与壳体2完全密封的结构设计，镜头1外形与壳体2开口内壁用胶水完全密封，保证模组内部与外界环境完全隔离，防尘效果更好；
本申请中，动子部分主要包括载体6、第一磁组件5和成像芯片13，减少了镜头1的重量，故电磁部分可小型化，进而使模组小型化；同时，减少了镜头1重量，可降低功耗，更适用于大像素模组设计；
壳体2设计为长方形，壳体2四角设计成台阶式，可起到预压作用，壳体2底面一边做成卡爪形，便于固定电路板出线端；
本申请的弹性件3为一个整体，只有两边有外框(即两个相对设置的支架)且两个外框分别与两个条形磁石相对；
本申请采用两个条状磁石，且两个条状磁石对称设置，且均为单极性磁石，可有效降低磁干扰；
本申请中，单个闭环线圈绕载体6一圈(即单个环形磁芯套设在载体6上)，通过两边不同的绕线可同时与两边磁铁产生同向的且对称分布的电磁力，可使壳体2设计为长方形，减小了外形设计尺寸。
滤光片7的两个对角设计成与载体6相对应的斜角，便于滤光片7与载体6组装，且可以达到防抖效果；
两边电磁力驱动芯片，载体6整体受力均匀，从而实现成像芯片13自动对焦；
设计有闭环反馈***，霍尔芯片12设计在电路板上，感应磁铁11固定在壳体2上，可实现成像芯片13精准对焦，使对焦更快，成像更加清晰。
本申请还提供一种电子设备，包括上述实施例中的摄像模组。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
