Abstract

The invention provides a sound loudness control method and a mobile terminal. The mobile terminal comprises a plurality of audio coding and decoding assemblies. The sound loudness control method comprises the steps of acquiring a plurality of sound analog signals outputted by the plurality of audio coding and decoding assemblies, wherein the plurality of audio coding and decoding assemblies stay at the same preset digital volume level; adjusting the amplification gain of the audio coding and decoding assemblies according to the plurality of sound analog signals, and enabling the plurality of sound analog signals to be the same in sound loudness at the preset digital volume level. According to the embodiment of the invention, sound analog signals outputted by each audio coding and decoding assembly at the same digital volume level are acquired firstly, and then the sound analog signals outputted by each audio coding and decoding assembly at the same digital volume level are enabled to be the same in sound loudness through adjusting the amplification gain of the corresponding audio coding and decoding assemblies, so that the sound loudness felt by users at the same volume level in difference scenes is consistent, and the audio output efficiency is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for controlling sound loudness and a mobile terminal. Background technique [0002] With the rapid development of smart terminals, users who use smart terminals have higher and higher requirements for sound quality, and there are more and more ways to configure two different audio output ports (one normal output and one high-fidelity HiFi output) in smart terminals. Due to the different functions of the two different audio output terminals, there are also differences in hardware design, resulting in inconsistent output levels of analog signal output levels of the same digital volume level in the smart terminal on different audio output terminals, that is, the output of each audio output segment. The voltage of the signal will be different at each digital volume level; the above situation makes the sound loudness perceived by the user at the same volume level in di...
