    摘要: The image blur correction device is an image blur correction device that corrects a blur of an image of a subject to be captured, and includes a movable frame, a fixed frame, a plurality of connection members, a plurality of actuators, a pair of magnets, and a magnetic body. The movable frame is displaceable along a plane orthogonal to an optical axis. The fixed frame faces the movable frame. The plurality of connection members connects the fixed frame and the movable frame to each other, and supports the movable frame so as to be displaceable. The plurality of actuators changes the position of the movable frame according to displacement of the movable frame. The pair of magnets is mounted on one of the fixed frame and the movable frame, and includes a first magnetic pole and a second magnetic pole. The magnetic body is mounted on the other of the fixed frame and the movable frame, and disposed to face the pair of magnets. The magnetic body has a flat surface facing the pair of magnets, the flat surface having four sides. A first side out of the four sides is located across the first magnetic pole and the second magnetic pole of the pair of magnets, and a second side intersecting the first side is located along one of the first magnetic pole and the second magnetic pole of the pair of magnets. The first side is linear, and the second side has a recessed shape or a protruded shape intersecting the first side.

    摘要: An optical unit with a shake correction function may include a movable body which may include an optical module and a holder for holding the optical module, and a gimbal mechanism which swingably supports the movable body with respect to a fixed body. The gimbal mechanism may include a movable frame which is a gimbal spring. The movable frame may include a supporting point part and a connecting part including a meandering part. The meandering part has a cross-sectional shape in which on the assumption that a direction perpendicular to first and second axial lines is a first direction and a direction perpendicular to the first direction and a meandering path of the meandering part is a second direction, a thickness in the second direction is larger than a thickness in the first direction of each plate-shaped spring which structures the movable frame.

    摘要: A voice coil motor and a corresponding focusing lens. A rotor assembly (22) is connected to a stator assembly (21) by means of an elastic connecting piece (23). A stator sleeve (211) is sleeved on a rotor sleeve (221). One of the stator sleeve (211) and the rotor sleeve (221) is a permanent magnetic material sleeve, and the other is a non-magnetic material sleeve. An assembly to which the non-magnetic material sleeve belongs also comprises a pre-magnetic element (222) and a drive coil (223). The premagnetic element (222) is made of a permanent magnetic or magnetized material, and is fixed relative to the non-magnetic material sleeve. The elastic connecting piece (23) is in a force balance state in a case without power because of pre-existing magnetic force between the pre-magnetic element (222) and the permanent magnetic material sleeve. Smaller electromagnetic force is required for driving the elastic connecting piece (23) to move, thereby reducing a drive current and power consumption.

    摘要: A voice coil motor includes a holder, a metal yoke, a carrier, a plurality of magnets, a coil and at least two spring plates. The magnets are disposed in the metal yoke. The coil is wound around the carrier and adjacent to the magnets. The spring plates are coupled to the carrier. The holder includes a first opening, a cylindrical sidewall and at least two radial protrusions. The cylindrical sidewall is disposed around the first opening. The radial protrusions protrude from the cylindrical sidewall. The metal yoke is coupled to the holder and includes a second opening and a plurality of inner walls. The carrier is movably disposed in the metal yoke and includes at least two radial enlarged portions and a plurality of notches. Each of the radial enlarged portions is disposed correspondingly to each of the radial protrusions.
