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.
