A lens driving device includes: a box-shaped lens carrier for fixing a lens barrel to the inside thereof which lens barrel is for guiding light from an imaging target to a photo detecting sensor, wherein the lens carrier has a first opening through which light from the imaging target enters, a second opening through which light toward the photo detecting sensor exits, and a third opening for mounting the lens barrel, wherein the third opening is formed between ends of two opposing side walls of the box-shaped lens carrier other than side walls being formed with the first opening and the second opening, wherein inner surfaces of the two opposing side walls are formed in parallel with respect to each other from the third opening to the center of the lens carrier.

Lens driving device, camera device and electronic apparatus

A lens driving device includes: a lens carrier for fixing a lens barrel to the inside thereof; a driving unit for moving the lens carrier along an optical axis direction of the lens barrel; and an elastic supporter for supporting the lens carrier so as to move freely along the optical axis direction of the lens barrel; wherein the lens carrier has an opening which opens toward a direction intersecting the optical axis direction of the lens barrel and through which opening the lens barrel is inserted.

The lens driving device includes: a housing, a lens holder, and first and second spring members that support the lens holder at both sides of the lens holder in an optical axis direction; wherein the first and second spring member each has a housing side fixing member fixed to the housing, a lens holder side fixing member fixed to the lens holder, and elastic arms therebetween. A first connecting point connecting the elastic arm with the housing side fixing member and a second connecting point connecting the elastic arm with the lens holder side fixing member are arranged offset to each other in a circumferential direction and an offset direction of the second connecting point to the first connecting point in the first spring member and an offset direction of the second connecting point to the first connecting point in the second spring member are opposite.

Lens driving device, camera device, and electronic apparatus

A lens driving device includes: a lens carrier for fixing a lens barrel to the inside thereof; a driving unit for moving the lens carrier along the optical axis direction of the lens barrel; and an upper leaf spring and a lower leaf spring attached to the lens carrier in a manner that a surface of the each upper leaf spring and lower leaf spring is oriented orthogonal to the optical axis direction at an upper part and a lower part of the lens carrier and so that the lens carrier is supported in a manner to move freely in the optical axis direction of the lens barrel; wherein the lens carrier has an opening through which the lens barrel can be inserted from the direction intersecting the optical axis direction of the lens barrel.

A lens driving device including: a lens holder; a coil mounted on the lens holder; at least one magnet disposed around the coil; a first and second spring members which support the lens holder at the both sides thereof in the optical axis direction so that the lens holder can move freely in the both directions of the optical axis of the lens in an initial state of no electric current to the coil; and an abutment surface to which the lens holder abuts when the lens holder moves toward one spring member against a biasing force of the one spring member; wherein the lens holder is exhorted a biasing force by the other spring member from the side of the other spring member to the side of the one spring member in the optical axis direction when the lens holder abuts against the abutment surface. Thus the lens driving device can support a lens holder in a stable fashion.

An optical structure is disposed on a surface of a device substrate, and a lens system for introducing external light into a solid-state image pickup device is placed in the center of the optical structure. The outer shape of the optical structure seen from the light incident side of the lens system is rectangular, and its plane shape forms a rectangular frame section. An intermediate structure is disposed between the device substrate and the optical structure. The intermediate structure has a fitting section for fitting the optical structure in a part of side faces of the frame section.

Camera module, manufacturing method of camera module, electronic apparatus, and manufacturing method of electronic apparatus

A lens driving apparatus includes: a first yoke having an inner peripheral wall and an outer peripheral wall placed to be concentric with each other and forming a rectangular U-shape cross section and a cylindrical shape; a second yoke placed at an outer side of the first yoke to be concentric with the first yoke and forming a rectangular U-shape cross section and a cylindrical shape; a base; a first magnet and a first coil arranged in a rectangular U-shape interior of the first yoke; a second magnet and a second coil arranged in a rectangular U-shape interior of the second yoke; a first lens support member; and a second lens support member. The second lens support member is placed at an inner peripheral side of the second yoke and has the second coil fixed onto an outer periphery thereof. The first lens support member is linearly moved in a direction of an optical axis of a lens by an electromagnetic force caused by passing current through the first coil. The second lens support member is linearly moved in a direction of an optical axis of a lens by an electromagnetic force caused by passing current through the second coil.

An electromagnetic actuator comprises: a magnet; a pole piece mounted to the magnet; a yoke facing the pole piece; a coil base having a vibration coil; leaf springs for supporting the coil base and a weight; a case for enclosing them; a cover for covering one side of the case; and a diaphragm having a voice coil, wherein the arms of the coil base are inserted through notches formed in the yoke, and the vibration coil and the voice coil is disposed in a gap in which the pole piece and the yoke face each other. The weight vibrates by the application of a low-frequency current to the vibration coil, and the diaphragm vibrates by the application of a high-frequency current to the voice coil.
