Embodiment Construction

[0075] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

[0076] In order to achieve noise reduction, this disclosure can be implemented in the following ways:

[0077] First, the voltage output information of the power supply is obtained, the voltage output information indicates that the power supply will output voltage according to the first change mode in the first time period in the future, and then supply power to electronic devices, such as mobile phone pads or notebooks;

[0078] Afterwards...

Abstract

The invention discloses a control method and apparatus and an electronic device. The method comprises the steps: acquiring voltage output information of a power source, wherein the voltage output information indicates that the power source output voltage according to a first change mode in a first time period; in response to the first change mode meeting a first control condition, controlling thepower source to output voltage in a second change mode; wherein in the first change mode, the first noise generated by an electronic device powered by the power source is greater than or equal to thesecond noise generated by the electronic device powered by the power source in the second change mode; in the electronic device that is powered by the power source, a first component is excited by voltage change of the power source to generate noise. By changing the change modes of the power source when voltage signals are output, the noise generated by the electronic device is reduced, the influence of the noise generated by the first component on a user is reduced, and thus use experience of the user to the electronic device is significantly improved after noise reduction.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a control method, device and electronic equipment. Background technique [0002] At present, during the use of notebooks and other devices, the changing voltage output of the CPU will cause the piezoelectric effect of the ceramic capacitor, which will cause resonance and emit obvious audio noise, which will affect the user experience. [0003] Therefore, there is an urgent need for a solution capable of controlling the audio noise of the device. Contents of the invention [0004] In view of this, the present disclosure provides a control method, including: [0005] Acquiring voltage output information of the power supply, the voltage output information indicating that the power supply will perform voltage output in a first change mode within a first time period; [0006] In response to the first change mode meeting the first control condition, controlling the power...
