Provided are a magnetic driving assembly and a stabilization driving device. The magnetic driving assembly includes a frame body, a magnetic piece, a coil carrier plate and multiple coils. The magnetic piece is disposed on the frame body, the coil carrier plate is disposed to be separated from the frame body, and the multiple coils are disposed to correspond to the magnetic piece, and an end of the coil carrier plate in a first direction is provided with at least one of the multiple coils configured to drive the coil carrier plate to linearly move in the first direction; an end of the coil carrier plate in a second direction is provided with at least two of the multiple coils configured to drive the coil carrier plate selectively to move linearly in the second direction or rotate around a third direction.

Magnetic driving assembly and stabilization driving device

Provided is a voice coil motor including a housing assembly, a base assembly, a zoom lens holder, a first electromagnetic drive assembly, a focusing lens holder and a second electromagnetic drive assembly. The zoom lens holder and the focusing lens holder are disposed in an accommodation space formed by the housing assembly and the base assembly. The first electromagnetic drive assembly is configured to drive the zoom lens holder to move in a front-back direction and includes a first magnetic steel portion and a first coil disposed opposite to the first magnetic steel portion. The second electromagnetic drive assembly is configured to drive the focusing lens holder to move in the front-back direction and includes a second magnetic steel portion and a second coil disposed opposite to the second magnetic steel portion.

Voice coil motor

A voice coil motor includes a housing, a first lens holder, a second lens holder, a first electromagnetic drive assembly, and a second electromagnetic drive assembly. The first electromagnetic drive assembly generates a first electromagnetic force to drive the second lens holder to move in a moving direction. The second electromagnetic drive assembly is adapted to drive the first lens holder to move along the moving direction. The first magnetic steel portion includes a first magnet and a second magnet. The first coil includes a first wire portion and a second wire portion. When the first coil is conducted, a direction of current in the first wire portion and a direction of current in the second wire portion have at least components in opposite directions. The present disclosure can solve the jam problem when zooming, and also increase the zoom stroke.

Voice coil motor with improved zooming performance

Provided is a prism driving device. The prism driving device includes a housing assembly, a prism holder disposed on the housing assembly in an angle adjustable manner, and an electromagnetic driving assembly. The electromagnetic driving assembly includes a magnet portion and a coil portion disposed opposite the magnet portion, where one of the magnet portion or the coil portion is disposed on the prism holder, the other one is disposed on the housing assembly, and the electromagnetic driving assembly is configured to adjust a tilt angle of the prism holder. One of the housing assembly or the prism holder is provided with a support protrusion and the other is provided with a groove, and at least a portion of the support protrusion is magnetically sucked into the groove.
