  • Publication number: 20240276088
    Abstract: The present invention relates to a driving structure for use in an optical actuator, including: a first driving part, which is suitable for mounting a lens and driving the lens to move transversely in the x-axis and y-axis directions; and a second driving part, which is suitable for driving a photosensitive chip to move transversely in the x-axis and y-axis directions, where the lens and the photosensitive chip are configured to be driven simultaneously and to move in opposite directions. Also provided in the present invention are a corresponding photographing method, an optically stabilizing photographing module, and a corresponding assembly method. The present application increases the stabilization travel and the stabilization response speed of the photographing module.

  • 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.
