Abstract

The invention provides a lens drive motor, a camera and a mobile terminal device. The lens drive motor comprises a shell, a lens support, a coil and a magnet component and is characterized in that thecoil winds the lens support and is arranged in the shell, the magnet component is arranged between the shell and the lens support, the part, corresponding to the magnet component, of the shell is made of a first material, the other part of the shell is made of a second material, and the magnetic permeability of the second material is smaller than that of the first material. By the lens drive motor, the problem that a lens drive motor in the prior art is insufficient in driving force is solved.

Description

technical field [0001] The present invention relates to the technical field of imaging equipment, in particular to a lens driving motor, a camera and a mobile terminal device. Background technique [0002] Since mobile terminal devices such as mobile phones generally require thinner structures, motors are often designed to be thinner in order to miniaturize the mobile terminal devices. And usually stainless steel shell. Due to the low magnetic permeability of the stainless steel casing, the problem of magnetic flux leakage is likely to occur, which in turn leads to the problem of insufficient driving force of the lens driving motor. Contents of the invention [0003] The main purpose of the present invention is to provide a lens driving motor, a camera and a mobile terminal device, so as to solve the problem of insufficient driving force of the lens driving motor in the prior art. [0004] In order to achieve the above object, according to one aspect of the present inven...
