Abstract

The invention relates to a call quality control method and device and a mobile terminal. The method comprises following steps of obtaining the environment type of a current environment of the terminal; determining gain of a microphone corresponding to the environment type according to the environment type and preset mapping relationships, wherein the mapping relationships comprise corresponding relationships of different environment types and different microphone gains; and amplifying the voice signals collected by the microphone according to the gain of the microphone corresponding to the environment type. According to the method of the embodiment provided by the invention, the currently collected voice signals can be rationally amplified by the microphone; therefore, distortion of the voice heard by an opposite side resulting from excessively amplifying the voice signals is avoided; a condition that the opposite side cannot hear the voice clearly because the voice signals are not amplified enough is avoided; and the call quality when a local side and the opposite side carry out a call is improved.

Description

technical field [0001] The present disclosure relates to communication technology, and in particular to a call quality control method, device and mobile terminal. Background technique [0002] With the continuous development of social economy, mobile terminals such as mobile phones have become indispensable tools in people's lives. People can make voice calls, chat online, shop, book tickets, etc. through mobile phones, which greatly facilitates people's lives. [0003] Taking a mobile phone as an example, when a call needs to be made with the opposite end through the mobile phone, the microphone on the local mobile phone collects the voice signal input by the user, and amplifies the voice signal and transmits it to the baseband part inside the mobile phone, so that the baseband part is amplified. The voice signal is processed by digital-to-analog conversion, frequency mixing, and RF power amplifier amplification, etc., and then sent to the peer end, so that the peer end can...
