Abstract

The invention provides a chip anti-shake device, a chip, a camera module and an electronic device. The chip anti-shake device passes through two sides of a mobile platform opposite to a substrate, one of which is provided with a first magnet, a second magnet and a third magnet and a fourth magnet, wherein the other is provided with a first coil unit that attracts or repels the first magnet, a second coil unit that attracts or repels the second magnet, and a second coil unit that attracts or repels the third magnet The third coil unit and the fourth coil unit attracting or repelling the fourth magnet, so that the first magnet and the second magnet are in the same row, the third magnet and the fourth magnet are in the same row, and the first magnet and the third magnet are adjacent , the second magnet is adjacent to the fourth magnet, and the mobile platform and the chip components on it are driven by the force between each magnet and the corresponding coil unit, and the mobile platform can be realized by changing the direction and size of the force. Movement in different directions, so as to realize jitter compensation for various movement modes of chip components.

Description

technical field [0001] The present application relates to the field of camera technology, and in particular, to a chip anti-shake device, a chip, a camera module and an electronic device. Background technique [0002] The camera function has become the standard configuration of electronic products such as mobile phones, tablets, notebook computers, wearable cameras, etc., and the camera function effect has gradually become one of the important characteristics of terminal electronic equipment. When using electronic products to take pictures, because the human body will have a certain frequency of physiological tremors under normal conditions, resulting in a decrease in the camera effect, the electronic devices are all equipped with anti-shake devices. [0003] At present, the anti-shake technologies for the image sensor chip in the camera module mainly include piezoelectric type, capacitive type and electromagnetic type. The electromagnetic type uses the attraction and repuls...
