Title:
CAMERA MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/001800
Kind Code:
A1
Abstract:
Embodiments of the present application provide a camera module and an electronic device. The camera module at least comprises an imaging unit and a position detection unit. The imaging unit comprises a moving part moving in a first direction. The position detection unit comprises two movable members and two fixed units. The two movable members are securely mounted on two opposite ends of the moving part respectively and located between the two fixed units, and the two movable members are spaced apart in a second direction. Each fixed unit comprises at least one fixed member, and the two fixed units are arranged opposite to each other in the second direction. One of the movable member and the fixed member is a magnet, and the other of the movable member and the fixed member is a magnetic sensor. Each magnetic sensor is used for detecting the magnetic field strength of the magnet corresponding to the magnetic sensor. The magnetic sensors and the magnets which work in conjunction with each other are arranged on the two sides of the moving part, so that a precision error caused by a distance change between the magnets and the magnetic sensors can be compensated, and the position detection precision can be improved.
