Embodiment Construction

[0062] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0063] figure 1 It is a flow chart of a call quality control method according to an exemplary embodiment. The call quality control method is applied to a mobile terminal, such as a mobile phone and other terminals that can be used for voice calls or video calls. This embodiment relates to a specific process in which the mobile terminal determines the gain of a microphone conforming to...

Abstract

The present disclosure relates to a call quality control method, device and mobile terminal. The method includes: acquiring the environment type of the environment where the terminal is currently located; determining the gain of the microphone corresponding to the environment type according to the environment type and a preset mapping relationship; the mapping relationship includes different environment types and different Correspondence of microphone gain: according to the gain of the microphone corresponding to the environment type, the voice signal collected by the microphone is amplified. The method of the embodiment of the present disclosure can make the microphone reasonably amplify the currently collected voice signal, so as to avoid excessive amplification of the voice signal and cause distortion of the sound heard by the peer end, and also avoid insufficient amplification of the voice signal to cause the peer end to listen to the sound. Unclear sound occurs, which improves the call quality when the local end communicates with the opposite end.

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...
