  • Publication number: 20240048830
    Abstract: The present disclosure provides a driving device and a camera module, wherein the driving device includes an auto-focus assembly and an optical image stabilizing assembly, the auto-focus assembly includes a focusing base, a focusing actuator and a fixed base, the focusing actuator includes at least one focusing coil and at least one focusing magnet disposed on an outer sidewall of the focusing base, the focusing coil is supported by the fixed base and corresponds to the focusing magnet so as to drive the lens to move along an optical axis direction of the lens by the focusing base in a case where the focusing coil is energized; and the optical image stabilizing assembly is supported by the fixed base and is transmissibly connected to the imaging assembly, so that the optical image stabilizing assembly drives the imaging assembly for vibration compensation.
