Problems solved by technology

[0002] The linear motor in the electronic device will vibrate when the power comes in, and the vibration will be transmitted to the camera module in the electronic device through the body of the electronic device, which will cause the camera module to produce abnormal noise under the action of the vibration; and, the camera There is a focus motor inside the module, and the vibration frequency between the linear motor and the focus motor is close. When the linear motor vibrates for a long time, it will drive the camera module to resonate, which may cause blurred pictures when users use the camera module to take pictures; That is to say, when the linear motor vibrates for a long time, it will interfere with the camera module and affect the imaging of the camera module.

Abstract

The application provides an electronic device, including a linear motor, a camera module and a controller. The linear motor has multiple driving frequencies; the camera module includes a voice coil motor, and the voice coil motor has a vibration frequency; wherein, a first driving frequency among the multiple driving frequencies is the same as the voice coil motor. The difference between the vibration frequencies of the coil motor is less than or equal to a preset threshold; the controller is used to control the linear motor to alternately vibrate at the plurality of driving frequencies.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to an electronic device. Background technique [0002] The linear motor in the electronic device will vibrate when the power comes in, and the vibration will be transmitted to the camera module in the electronic device through the body of the electronic device, which will cause the camera module to produce abnormal noise under the action of the vibration; and, the camera There is a focus motor inside the module, and the vibration frequency between the linear motor and the focus motor is close. When the linear motor vibrates for a long time, it will drive the camera module to resonate, which may cause blurred pictures when users use the camera module to take pictures; That is to say, when the linear motor vibrates for a long time, it will interfere with the camera module and affect the imaging of the camera module. Contents of the invention [0003] The present a...
