Abstract

The invention provides a noise reduction method and device. The noise reduction method comprises: obtaining the noise value on the main board of a terminal when the terminal is connected to the cell site of a first work frequency range, and performs voice communication; determining whether the noise value is qualified; and if the noise value is determined to be unqualified, switching the terminal to the second work frequency range connected to the cell site so as to reduce the main board noise of the terminal, wherein the maximum power value of the second work frequency range is smaller than the maximum power value of the first work frequency range. The noise reduction method and device can automatically reduce the noise of the terminal, improve test efficiency, and reduce production costs.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a noise reduction method and device. Background technique [0002] With the increasing popularity of terminals, especially the development of smart phones, users have higher and higher requirements for smart phones, especially for noise. [0003] The noise of the main board of the mobile phone directly affects the user experience, so the mobile phone put into the market must meet the noise standard. During the development process, the board-level TD-nosie (Time Division-nosie, time-division noise) problem is encountered. There are two main solutions at present. The first is to find the sounding capacitor and change the capacitor to a low-noise capacitor; the second is to change the wiring on the motherboard, widen and shorten the power supply wiring, and increase the large capacitor at the same time to ease the call. amplitude of voltage fluctuations. However, the above methods...
