第三方面，提供一种移动终端，包括如上任一实施例所述的拍摄模组。

请参阅图1至图3，现对本申请提供的拍摄模组100进行说明。所述拍摄模组100，包括机座11、图像传感器12、镜头14、音圈电机13和至少一个电润湿镜片20，图像传感器12安装于机座11上，镜头14设于图像传感器12前方，音圈电机13安装于机座11上，镜头14安装于音圈电机13中，通过音圈电机13来驱动镜头14移动，以实现对焦。电润湿镜片20沿镜头14的光轴设置，且电润湿镜片20设于图像传感器12的前方，电润湿镜片20为基于电润湿效应的镜片。电润湿效应指通过改变液滴与绝缘基板之间电压，来改变液滴在基板上的润湿性，即改变接触角，使液滴发生形变、位移的现象。当电润湿镜片20上不施加电压时，电润湿镜片20相当于透光平板；当电润湿镜片20上施加电压时，电润湿镜片20相当于透镜，即电润湿镜片20上施加电压，可以改变电润湿镜片20的曲率。
当电润湿镜片20上不施加电压时，图像传感器12、镜头14、音圈电机13可以实现常规的对焦拍摄。当电润湿镜片20上施加电压时，使电润湿镜片20相当于透镜，实现类似显微镜的放大效果，可以缩短对焦距离，实现微距拍摄。当然，通过改变电润湿镜片20上施加的电压，也可以实现对焦。另外，通过音圈电机13与电润湿镜片20的配合，还可以实现更为精准的对焦，并且可以实现更小距离的拍摄。当图像传感器12、镜头14、音圈电机13组合可以实现微距拍摄时，则通过与电润湿镜片20的配合，还可以实现超微距拍摄。
本申请实施例的拍摄模组100，通过设置镜头14、图像传感器12和音圈电机13，同时在图像传感器12的前方设置至少一个电润湿镜片20，当电润湿镜片20上不施加电压时，电润湿镜片20相当于透光平板，则该拍摄模组100可以实现常规对焦拍摄；当电润湿镜片20上施加电压时，可以改变电润湿镜片20的曲率，使电润湿镜片20相当于透镜，实现类似显微镜的放大效果，进而可以缩短对焦距离，实现微距拍摄。
在一个实施例中，请参阅图1至图3，音圈电机13包括线圈133、磁体132、弹片134和机壳131，机壳131安装于机座上，弹片134固定于机壳131上，镜头14安装于弹片134上，通过弹片134来支撑住镜头14。线圈133安装在镜头14上，则在线圈133上通电时，线圈133产生的感应磁场与磁体132作用，以驱动线圈133移动，进而通过线圈133带动镜头14移动，以实现对焦。在一些实施例中，也可以将磁体132与镜头14固定相连，而线圈133安装在机壳131上。
在一个实施例中，线圈133环绕镜头14，磁体132均匀分布于线圈133的周向，以便在驱动线圈133移动时，使线圈133受力均匀，便于驱动镜头14平稳移动。
在一个实施例中，可以通过改变电润湿镜片20上施加的电压，以控制光线偏转，进而实现小角度防抖。
在一个实施例中，请参阅图1至图3，弹片134为多个，设置多个弹片134，不仅可以更稳定支撑住镜头14，而且可以平衡力矩，保证镜头14平稳移动。
在一个实施例中，弹片134插入式注塑成型在镜头14中，以便弹片134与镜头14更稳定的连接。
在一个实施例中，请参阅图1至图3，镜头14包括镜筒142和调光透镜141，调光透镜141设于镜筒142中，通过镜筒142来支撑住调光透镜141。
在一个实施例中，请参阅图1至图3，调光透镜141为至少一个，以实现聚光调焦的作用。本实施例中，调光透镜141为四片，在其它一些实施例中，调光透镜141也可以为一片、两片、三片、五片、六片等等数量。
在一个实施例中，请参阅图1至图3，至少一个电润湿镜片20与镜头14固定相连，在镜头14上固定电润湿镜片20，则在音圈电机13驱动镜头14移动时，可以同步驱动电润湿镜片20移动，则在音圈电机13对焦后，可以通过电润湿镜片20来进行放大，实现超微距拍摄。

在一个实施例中，请参阅图1，围坝21可以作为第二电极25，以方便加工制作。当然，一些实施例中，第二电极25也可以设置在围坝21的外围。还有一些实施例中，第二电极25也可以安装在围坝21上，并插入到第一透光液体26中。

在一个实施例中，第一透光液体26也可以是水。当然，其它一些实施例中，第一透光液体26也可以是其他导电的液体。
在一个实施例中，请参阅图1，第一电极24设置在第二透光板23背离第一透光板22的一面。在其它一些实施例中，也可以将第一电极24设置在第二透光板23中。

通过音圈电机13驱动镜头14移动，以实现机械对焦；通过电润湿镜片20施加电压，以通过调节焦距，实现光学对焦，从而通过机械对焦与光学对焦结合，提高对焦精度与速度，并且实现更近距离的拍摄。
在一个实施例中，请参阅图1，音圈电机13的线圈133不通电，并且电润湿镜片20上不施加电压，电润湿镜片20等效为平板玻璃，该拍摄模组100可以实现对焦远景。
在一个实施例中，请参阅图2，在音圈电机13的线圈133上通电，在磁体132的磁场中受力驱动镜头14及电润湿镜片20整体向前移动，此时电润湿镜片20等效为平板玻璃，电润湿镜片20不聚焦光线，可以实现近距离对焦，如可以实现2-7cm的微距对焦。
在一个实施例中，请参阅图3，物体对焦后，开始给电润湿镜片20施加组合电压，电润湿镜片20的焦距改变，使该拍摄模组100的对焦距离更近，视角也更加小，产生显微镜放大效果，可以进一步减小对焦距离，实现约1cm或1cm以下的超微距对焦。
