The technology of this application relates to an actuating device, a camera module, and an electronic device. In the actuating device, an actuator is configured to include an actuating magnetic component, a power supply apparatus, and at least one coil. The power supply apparatus is electrically connected to the coil, and the coil is disposed in a magnetic field of the actuating magnetic component. When a current is supplied to the coil, the coil or the actuating magnetic component moves under an action of the magnetic field. In this case, the coil or the actuating magnetic component can drive a motor carrier to move, to drive a lens of the camera module to move, so that zooming of the camera module is completed.

An optical element driving unit includes a stationary body, a carrier, a supporting mechanism and an electromagnetic driving assembly. The supporting mechanism is connected to the carrier and the stationary body and provides the carrier with a degree of freedom of movement relative to the stationary body. The carrier can be driven to move by the electromagnetic driving assembly. The electromagnetic driving assembly includes a driving coil, a driving magnet and a ferromagnetic element. The driving coil is disposed on the carrier. The driving magnet is disposed on the stationary body. The ferromagnetic element is one-piece formed and embedded in the carrier, and the ferromagnetic element includes a magnetic field guiding part and an electrical connection part. The magnetic field guiding part faces the driving coil and/or the driving magnet. The electrical connection part is exposed on a surface of the carrier and electrically connected to the driving coil.

The present embodiment relates to a camera module comprising: a bobbin, which has a through-hole formed therein; a lens module, which is accommodated in the through-hole and is coupled to the bobbin; a protrusion formed to protrude from the outer peripheral surface of the lens module; and a recess formed to be recessed from the inner peripheral surface of the bobbin so as to accommodate at least a part of the protrusion, wherein the recess comprises a first guide portion, which extends downwards from the upper end of the bobbin, and a second guide portion, which extends so as to slope from the first guide portion.

This camera actuator comprises: an optical path bending member; a lens unit disposed at a subsequent stage of the optical path bending member; a first actuator that is disposed near the optical path bending member and displaces the optical path bending member; and a second actuator and a third actuator that are disposed near the lens unit so as to be apart from each other in a first direction, and that respectively displace the lens unit in a second direction and a third direction that are orthogonal to the first direction and orthogonal to each other. As a result, the present invention provides a camera actuator capable of improving the degree of freedom of design around the optical path bending member.

A shake correction optical unit with a shake correction function may cause a movable body including an optical module to swing around an X axis and a Y axis that are perpendicular to an optical axis L. A flexible printed board may include a second folded portion drawn from the movable body in a +Y direction, and bent in a direction of the optical axis L and folded once; and a first folded portion bent to extend from the second folded portion in the +Y direction and folded once. At least one of the second folded portion or the first folded portion may be thus easily bendable when the movable body swings in either direction around the X axis or around the Y axis.

An optical element drive device includes a movable section and a fixed section. The movable section includes a first magnetic field generator for generating a first magnetic field and is drivable in a motion direction. The fixed section includes a sensor unit. The sensor unit carries out a detection based on the first magnetic field and a bias magnetic field different from the first magnetic field.

The present disclosure provides an optical unit with shake correction function capable of preventing a thrust receiving member, which fixes a sphere, from falling off from the movable body in an optical axis direction. According to some embodiments of the present disclosure, a thrust receiving member to which a first sphere is fixed is held by a holding portion formed of the cutout recess provided in a fixed body. A bottom wall surface of the holding portion makes contact with a bent plate portion of the thrust receiving member from −Z direction side. Further, locked surface parts provided on a pair of side wall surfaces of a holding portion make contact, from +Z direction side, with a pair of locking plate portions protruding from a bent plate portion in circumferential direction in the thrust receiving member.

In some embodiments, a camera includes an optical package, a camera actuator for moving the optical package, a camera cover, and an impact absorption member to prevent contact between the camera cover and the lens carrier. In some embodiments, the camera actuator includes a lens carrier moveably mounted to a camera cover.
