Claim 0:
1. An actuator for a camera unit, comprising:
a seat configured to be assembled with a first lens and a fluid lens of the camera unit;
a stator assembly fixedly connected to the seat;
a focusing mover assembly configured to be connected with the fluid lens; and
an anti-shake mover assembly configured to be connected with the first lens,
wherein the focusing mover assembly is configured to move along a first direction of the seat by interacting with the stator assembly, for adjusting a curvature of the fluid lens, and the anti-shake mover assembly is configured to translate in a plane perpendicular to the first direction by interacting with the stator assembly, for driving the first lens to move,
wherein the stator assembly comprises a first acting member, the focusing mover assembly comprises a second acting member, the anti-shake mover assembly comprises a third acting member, the first acting member interacts with the second acting member so that the focusing mover assembly moves in the first direction, and the first acting member interacts with the third acting member so that the anti-shake mover assembly translates in the plane perpendicular to the first direction,
wherein the stator assembly further comprises:
an annular bracket fixedly connected to the seat,
wherein the first acting member is arranged to the annular bracket along a circumferential direction of the annular bracket,
wherein the first acting member comprises a stator magnet, the second acting member comprises a focusing coil, and the third acting member comprises an anti-shake coil,
one or more stator magnets are arranged to the annular bracket along the circumferential direction of the annular bracket,
each stator magnet has a first polarity on a side facing the anti-shake mover assembly, and has a second polarity on a side facing the focusing mover assembly.
