Problems solved by technology
In this way, although it can play a role in driving the movement of the photosensitive chip, the cost is relatively high.
Moreover, for different types of cameras, motors of different sizes and shapes need to be used, which leads to an increase in the cost of the supply chain
Therefore, when realizing the mobile optical image stabilization of the photosensitive chip, the cost of the existing camera module is relatively high

Embodiment Construction
[0034] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0035] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a camera module, and when a coil is electrified, the coil interacts with a magnet to generate an electromagnetic acting force. The circuit board can slide relative to the base under the driving of the electromagnetic acting force, so that the photosensitive chip is driven to displace relative to the lens assembly, optical axis deviation of the lens assembly caused by shaking is compensated, and optical anti-shaking is realized. The magnet and the coil are simple in structure, low in cost, capable of being separately installed and convenient to assemble. In addition, for camera modules of different models and sizes, the driving assembly does not need to be additionally designed, and only the magnet and the coil need to be arranged at proper positions. Therefore, the camera module is low in cost while optical anti-shake is realized. In addition, the invention also provides a mobile terminal.
Description
technical field [0001] The invention relates to the technical field of optical imaging, in particular to a camera module and a mobile terminal. Background technique [0002] Optical image stabilization is a widely recognized anti-shake technology. It compensates the vibrating optical path through movable parts, so as to reduce the blurring of photos. Optical anti-shake technology is mainly divided into two categories, namely lens mobile optical anti-shake, and photosensitive chip mobile optical anti-shake. [0003] The lens-moving optical image stabilization has a complex structure, and is generally not suitable for application in camera modules of mobile terminals. Therefore, the photosensitive chip mobile optical image stabilization has received more and more attention. The core principle of the photosensitive chip mobile optical image stabilization is: under the action of the driving force, the photosensitive chip can be displaced, thereby compensating for the shift of ...
