Problems solved by technology

The voice coil motors of existing mobile phone cameras generally only have lens anti-shake. With the rapid development of the mobile phone industry, technological innovations are getting faster and faster. Consumers have increasingly stringent requirements for mobile phone camera functions, and mobile phone cameras have always moved towards the level of SLR cameras. Forward; therefore, it is necessary to design a voice coil motor that can realize autofocus function and OIS anti-shake function

Abstract

The present invention provides a voice coil motor, which includes an auto-focus mechanism and a fuselage anti-shake mechanism. The auto-focus mechanism includes a first base, a cover, a coil assembly arranged between the first base and the cover, and a The cover and the magnetic assembly located around the coil assembly; the fuselage anti-shake mechanism includes a second base located on the side of the first base away from the cover and a coil module positioned on the second base. After the coil assembly is powered on, it is connected to the magnetic assembly The electromagnetic force is generated between the coil module to drive the coil assembly with the lens to move axially, which can realize the auto-focus function; after the coil module is powered on, the electromagnetic force is generated between the magnetic assembly to drive the second base and drive the sensor with the photosensitive chip The coil module moves relative to the first base to realize the OIS anti-shake function. The invention also provides a camera and electronic equipment provided with the voice coil motor.

Description

technical field [0001] The present invention relates to the field of electronic control devices, in particular to a voice coil motor, a camera provided with the voice coil motor, and an electronic device provided with the camera. Background technique [0002] The anti-shake of cameras on the market is divided into lens anti-shake and body anti-shake. The lens anti-shake is to use the displacement of the lens group to change and correct the optical path when shaking, so as to achieve anti-shake compensation effect; the body anti-shake is used. It is the displacement of the photosensitive chip to perform anti-shake compensation. The voice coil motor of the existing mobile phone camera generally only has the lens anti-shake. With the rapid development of the mobile phone industry, the technological innovation is getting faster and faster, and the consumer users have increasingly strict requirements for the camera function of the mobile phone, and the mobile phone camera has alw...
