Drive device and electronic apparatus

The invention provides a driving device and electronic equipment. The driving device can be applied to the electronic equipment. The driving device comprises a variable aperture. The piezoelectric ceramic of the variable aperture is used for deforming under signal control so as to drive the rotating ring of the variable aperture to rotate relative to the base of the variable aperture, each blade of the variable aperture rotates relative to the rotating ring and slides relative to the first convex part of the base, and the aperture of the aperture hole of the variable aperture is changed. The aperture hole change range of the variable aperture is not easily influenced by the external magnetic force of the variable aperture. 本申请提供一种驱动装置以及电子设备。驱动装置可以应用于电子设备。驱动装置包括可变光圈。可变光圈的压电陶瓷用于在信号控制下发生形变，以驱动可变光圈的转动环相对可变光圈的底座转动，可变光圈的每个叶片均相对转动环转动，并相对底座的第一凸部滑动，可变光圈的光圈孔的孔径发生变化。本申请的可变光圈的光圈孔变化范围不容易受可变光圈的外部磁力的影响。
