Abstract
An actuator includes a seat body a stator magnet, a mover assembly and a driving chip. The stator magnet is in the seat body and is connected to the seat body; the mover assembly includes a coil circuit board, the coil circuit board includes a first electrically conductive coil, and the first electrically conductive coil, when energized, interacts with the stator magnet to drive the mover assembly and the stator magnet to move relative to each other; and the driving chip is located on the coil circuit board and is connected to the first electrically conductive coil, and is used for connecting to an external power supply circuit to supply power to the first electrically conductive coil.
