Abstract: Disclosed are a battery and an electronic device, including a housing, a sealing cover, and a battery cell. The housing has an accommodation cavity, and the battery cell is located in the accommodation cavity. The housing is provided with a liquid injection hole. An upper surface of a peripheral edge of the sealing cover is provided with a first step, and the first step divides the sealing cover into a first cover area and a second cover area. The thickness of the second cover area is less than or equal to a thickness of the housing at a seal-welding position with the second cover area. The battery provided in embodiments of the present disclosure has good seal-welding performance, to resolve problems of low battery yields, difficulty in mass production, and failure to achieve expected safety and stability due to poor seal-welding performance.

Abstract: A camera lens comprises a lens barrel, a front lens group disposed inside the lens barrel and proximate to an object side, a rear lens group disposed inside the lens barrel and proximate to an image side and comprises a first lens proximate to the image side, the first lens comprising a first optically effective part comprising a first outer edge, an effective aperture region comprising a second outer edge, and a first cutting edge, and a first non-optically effective part disposed around the first outer edge and comprises a first non-effective region disposed along the second outer edge, a second non-effective region disposed along the first cutting edge and comprising a third outer edge, and a second cutting edge on the third outer edge, and a cutting surface on the first outer side wall, proximate to the rear lens group, and faces the second cutting edge surface.

Abstract: A voice coil motor for driving a liquid lens and a lens assembly having a voice coil motor, where the voice coil motor includes a plurality of sub motor parts. The 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, coupled to the 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.
