Description

A camera unit and mobile terminal

technical field

The present application relates to the field of camera unit technology, in particular to a camera unit and a mobile terminal.

Background technique

At present, mobile terminals are more and more closely connected with people's lives. For example, the camera function of a mobile terminal can record people's wonderful moments. Good image quality requires a good camera unit.

At present, the focus of the camera unit is the most widely used electromagnetic focus. The magnitude of the magnetic force is controlled by the magnitude of the current in the energized coil, and then the movement of the lens carrier is controlled. However, the lens carrier in this way is in a suspended state. When the lens carrier is subjected to a small external force, such as a mobile phone swinging in the hand, the lens carrier will shift and collide with the bottom base, thereby generating noise; After being subjected to a large external force, for example, the mobile phone slips from the hand, the lens carrier will have a large displacement and collide with the base at the bottom, thereby making the camera unit invalid and affecting the normal use of the mobile terminal.
