Abstract

The present invention provides a lens driving device that can suppress unwanted vibrations and resonances of a lens holding member with a simple and easy-to-manufacture configuration. A lower leaf spring (17) has, at four corners, an annular holding portion (17a) in which a through hole (17a1) through which suspension wires (411, 412, 413, 414) are inserted is formed. A damping member (9) that contacts both of the annular holding portion (17a) and the intermediate portion (85) of the suspension wires (411, 412, 413, 414) is held in the annular holding portion (17a).

Description

technical field [0001] The present invention relates to a lens driving device, and more particularly to a lens driving device used in a relatively small video camera mounted on a mobile phone or the like. Background technique [0002] In recent years, the demand for high performance and high functionality of cameras mounted on mobile phones and the like has increased, and lens driving devices mounted on mobile phones with cameras and the like have been required to have not only an autofocus function but also an anti-shake function. [0003] Such a lens driving device has a structure in which a conventional AF camera module called an imaging unit (movable module) is supported by four suspension wires and driven in two axial directions perpendicular to the optical axis, thereby Construct for correcting jitter. [0004] Specifically, one end of the four linear suspension wires is fixed to the four corners of the base, and the other end is inserted into the through-hole of the ...
