Abstract:
A camera module includes a coil member, a magnet member, and a sensor member. The coil member is positioned on a first surface of a fixed unit. The magnet member is positioned on a movable unit and facing the coil member. The sensor member is positioned on a second surface of the fixed unit and configured to sense a position of the movable unit.
Abstract:
A camera module includes a fixed unit having an accommodating space; a moveable unit disposed in the accommodating space; an actuator configured to drive the movable unit in an optical axis direction; a substrate, disposed on a first side surface of the fixed unit, including a coil member of the actuator disposed on a first surface of the substrate; and connection pads, disposed on a second surface of the substrate, electrically connected to the coil member.
Abstract:
There is provided a vibration generating device including: a housing having an internal space; a vibrating member of which both end portions are fixed to the housing; a piezoelectric element fixed to a top surface of the vibrating member; a mass body disposed on the piezoelectric element; and a coupling member connecting the mass body and the vibrating member to each other and including a hook portion connected to the vibrating member by elastic deformation.
Abstract:
A camera module is provided. The camera module includes a housing; a focus adjustment unit disposed in the housing; and a shake correction unit disposed in the housing, wherein the housing includes a first shake correction driving magnet and second shake correction driving magnet that provide a driving force to move the shake correction unit in a first direction intersecting an optical axis and a second direction intersecting the optical axis and the first direction, and a focus adjustment driving coil providing a driving force to move the focus adjustment unit in the optical axis direction. The housing further includes first to third yokes respectively disposed on a surface of the first magnet, a surface of the second magnet, and a surface of the focus adjustment driving coil.
Abstract:
An actuator driving device includes: a linearizer configured to linearize a first signal, indicative of a displacement of a lens module, to generate a second signal; a position controller configured to generate a position control signal in response to the second signal and a control input signal indicative of a target location of the lens module; and a driver configured to drive an actuator in response to the position control signal.
