The lens structure includes: a lens tube; a first lens located on a first end-face of the lens tube, where the first lens includes a light converging region and an edge region located at an edge around the light converging region; a light shielding structure covering the edge region of the first lens; and at least one second lens located inside the lens tube. Based on the lens structure provided in the embodiments of this application, the first lens is disposed on an outer side of a housing of the lens tube. Therefore, an adjustment degree is relatively high, and convenience and flexibility are relatively desirable. In addition, an optical axis of the first lens and an optical axis of the at least one second lens are aligned at a relatively high extent, thereby improving quality of the lens structure and a yield of the lens structure. In addition, based on the lens structure provided in the embodiments of this application, it can be further distinguished whether a reason for a quality problem of the lens structure is an assembly problem of the at least one second lens or a position arrangement problem of the first lens.

The first reflector (12a) is configured to direct an optical axis from a first direction to a second direction. The second reflector (41a) is configured to direct the optical axis from the second direction to a third direction. In this way, the photosensitive surface (4321a) of the chip module (43a) may not be limited by a size of the camera module (100a) in a direction that is perpendicular to the second direction, and a large photosensitive surface design of the photosensitive surface of the chip module can be implemented. The stabilization motor (42a) includes a base (421a), a movable circuit board (422a), and a driving mechanism (424a). The driving mechanism (424a) of the stabilization motor (42a) includes a magnet (4241a) and a coil (4242a). The coil (4242a) is configured to: when being energized, cooperate with the magnet (4241a) to drive the movable circuit board (422a) to move on a plane that is perpendicular to the third direction or tilts relative to the third direction. The structure of the driving mechanism (424a) of the stabilization motor (42a) is simple.

摘要： This application provides a voice coil motor for driving a liquid lens and a lens assembly having a voice coil motor. The voice coil motor includes a plurality of sub motor parts. The plurality of sub motor parts can be independently controlled. The sub motor part includes: an unmovable part; a movable part, which can move along an optical axis direction relative to the unmovable part; a connection elastic piece, connected to a liquid lens and the movable part, where when a force is applied to the movable part in the optical axis direction, the movable part drives the connection elastic piece to squeeze the liquid lens, the connection elastic piece is a plate spring, and a stiffness coefficient of the connection elastic piece in the optical axis direction is greater than a stiffness coefficient of the connection elastic piece in a direction perpendicular to the optical axis direction; and a drive circuit part, configured to control a moving distance of the movable part. The voice coil motor in the foregoing technical solution can accurately implement auto focus and optical image stabilization of the liquid lens.

摘要： This application provides an optical image stabilization module and an electronic device. The optical image stabilization module includes a first bracket, a second bracket, and a third bracket that are nested in sequence from inside to outside, and an optical lens module fixed on the first bracket. A first connection assembly is arranged between the first bracket and the second bracket, to enable the first bracket and the second bracket to form a rotational connection about a first rotation axis. A second connection assembly is arranged between the second bracket and the third bracket, to enable the second bracket and the third bracket to form a rotational connection about a second rotation axis. The first rotation axis, the second rotation axis, and an optical axis of the camera are perpendicular to each other. When the electronic device on which the optical image stabilization module is mounted shakes, the optical image stabilization module can drive the optical lens module to rotate about the first rotation axis and the second rotation axis, to compensate for an angle variation of the optical lens module caused by a shake of the electronic device, so that the optical lens module maintains an original field of view, thereby implementing large-angle optical image stabilization.
