Abstract

The embodiment of the invention provides a method for preventing resonance of a motor and a vibrator and a mobile terminal. The mobile terminal includes a processor, a camera motor module and a vibrator, wherein the camera motor module includes a motor driving chip, a center-mounted camera motor and a base, characterized in that the method includes the following steps: when receiving a vibration instruction of the vibrator, the processor sends a movement instruction to the motor driving chip; and the motor driving chip controls the center-mounted camera motor to move to contact the base according to the movement instruction. By moving the center-mounted camera motor to contact the base before the vibrator vibrates, the problem that the center-mounted camera motor and the vibrator have resonance due to the vibration of the vibrator can be prevented, and thus the problem that the center-mounted camera motor and the side wall of the mobile terminal collide to generate an abnormal sound ordamage the center-mounted camera motor due to the resonance can be further avoided.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method for preventing resonance between a motor and a vibrator and a mobile terminal. Background technique [0002] At present, with the development of science and technology, there are more and more photographing applications on mobile terminals, and users' requirements for various photographing indicators have become higher and higher. Among them, the speed of taking pictures is one of the important indicators, especially when you want to capture a scene, you need to focus faster to improve the quality of pictures. The traditional autofocus uses a common preload motor, which takes a long time to focus and correspondingly slows down the speed of taking pictures. In order to solve the above-mentioned problem of slow photographing speed, at present, a center-mounted camera motor is mainly used for fast focusing in mobile terminals. [0003] When the motor of t...
