Noise reduction method and electronic device
By controlling the power supply of the camera module motor when the speaker is playing audio at high volume, the movement of the lens avoids resonance noise, thus solving the problem of the lens shaking and hitting the inner wall of the camera module, improving the user experience and reducing power consumption.

AI Technical Summary
Technical Problem
In electronic devices, the lens of a camera module may vibrate and impact the inner wall of the camera module due to resonance with the speaker, generating noise and affecting the user experience.
Method used
By controlling the camera module's motor to power on when the speaker plays audio at a high volume, the lens is moved away from its initial position, thus avoiding noise caused by resonance. The noise reduction module and the camera module's conflict are handled by combining the camera module's priority.
Benefits of technology
It effectively reduces noise, improves the user experience, and reduces power consumption when noise reduction is not needed, thus solving the noise problem caused by lens resonance.

Abstract
The present application relates to the field of noise reduction. Disclosed are a noise reduction method and an electronic device, which are used for reducing noise from the electronic device, thereby improving the user experience. The method is applied to the electronic device. The electronic device comprises a camera compact module and a loudspeaker, wherein the camera compact module comprises a motor and a lens, and the motor is used for controlling the lens to move. The method comprises: in response to a first operation, an electronic device not powering on a motor, and a lens being at an initial position, wherein the first operation is used for controlling the electronic device to play first audio at a first volume by means of a loudspeaker; and in response to a second operation, the electronic device powering on the motor, and controlling, by means of the motor, the lens to move away from the initial position, wherein the second operation is used for controlling the electronic device to play the first audio at a second volume by means of the loudspeaker, the second volume being greater than the first volume.
