摘要： A lens drive apparatus includes a damper compound that is disposed between at least one protrusion and a fixed member and that suppresses undesired resonance of an auto-focusing lens driving section in a direction of an optical axis. The at least one protrusion protrudes from a magnet holder in the direction of the optical axis toward the fixed member and is inserted into at least one hole of a leaf spring provided to the auto-focusing lens driving section.

摘要： A lens holder driving device includes a lens holder moving portion, a fixed member, suspension wires, and a damper compound. In the lens holder moving portion, a lens holder moves in an optical axis and in first and second directions which are orthogonal to the optical axis and which are perpendicular to each other. The fixed member is disposed apart from the lens holder moving portion in the direction of the optical axis. The suspension wires have first end portions fixed to the fixed member at outer regions thereof, extending along the optical axis, having second end portions fixed to an elastic member mounted to the lens holder moving portion, and swingably supporting the lens holder moving portion in the first direction and the second direction. The damper compound is disposed so as to enclose at least one suspension wire and suppresses undesired resonance in the lens holder moving portion.

摘要： A lens drive apparatus includes a plurality of protrusions that protrude from an end of a magnet holder in a direction of an optical axis toward an inner wall surface of a cover and function as a fracture prevention supporting member. The plurality of protrusions are configured to support prevention of fracture in a plurality of suspension wires by contacting the inner wall surface of the cover when a magnet holder moves in the direction of the optical axis.

摘要： A lens driving device includes: a lens holder; a first coil wound onto the lens holder around the optical axis direction; a plurality of magnets having a first surface and a second surface perpendicular to the first surface, the magnets being disposed in a state in which the first surface opposes a circumferential surface of the first coil; a magnet holder that fixes the magnets apart from each other; a yoke constituting, together with the magnets, a magnetic circuit having a magnetic flux that traverses the first coil; a second coil provided opposite the second surface of the magnets; and a base on which the second coil is disposed. An auto-focus lens driving part that includes the lens holder, the first coil, the magnets, the magnet holder, and the yoke is held on the base so as to allow relative displacement in a direction perpendicular to the optical axis.
