摘要： A lens actuator has a carrier, a cover, a first spring, a second spring, a coil, and a magnet. The carrier with a cylindrical shape is provided with a hollow section formed along a first direction, and has a holding section formed on one side of the first direction. The hollow section has a shape configured to mount a lens barrel therein. The cover, which is disposed on the side having the holding section of the carrier, has a supporting section that meets with the holding section of the carrier. The first spring and the second spring make a resilient contact with each of both surfaces in the first direction of the carrier. The coil is circumferentially disposed on the carrier so as to face the magnet. Of the coil and the magnet, one is mounted on the carrier and the other is disposed on the outer or the inner periphery of the carrier.

摘要： A lens driving device has a carrier, a coil, an upper spring, a lower spring, a yoke, a magnet, and a lower member. The carrier is cylindrical and has a hollow part along a vertical direction so that a lens can be carried. The coil is fixed to an outer peripheral surface of the carrier. The upper spring is arranged over the carrier, and fixed to the yoke. The lower spring is arranged below the carrier. The yoke is formed into a box shape having a side wall and an opening on the lower side, and arranged around the carrier. The magnet is arranged in the yoke so as to be opposed to the coil. The lower member is arranged below the yoke. The lower member has a projection part connected to the yoke. The projection part is inserted between an inner surface of the side wall of the yoke and an outer surface of the magnet and connected to the yoke. Thus, the yoke and the lower member can be connected such that space for the magnet to be arranged in the yoke is less affected.
摘要翻译：透镜驱动装置具有载体，线圈，上弹簧，下弹簧，轭，磁体和下部构件。载体是圆柱形的，并且沿垂直方向具有中空部分，从而可以承载透镜。线圈固定在载体的外周面上。上弹簧布置在载体上，并固定到轭。下弹簧布置在托架的下方。轭形成为具有侧壁和在下侧上的开口的盒形，并且布置在载体周围。磁铁配置在磁轭中以与线圈相对。下部构件设置在轭架的下方。下部构件具有连接到轭的突起部。突出部分插入在轭的侧壁的内表面和磁体的外表面之间并连接到轭。因此，轭和下构件可以被连接，使得要布置在轭中的磁体的空间受到较小的影响。
