Audio system, audio control method and mobile terminal with audio system

Abstract

The invention provides an audio system, an audio control method and a mobile terminal with the audio system. The audio system comprises a voltage input terminal and a digital filter; wherein the voltage input terminal inputs a first electrical signal; and the digital filter is arranged between the voltage input terminal and an audio processing circuit; the digital filter connects the voltage inputterminal, receives the first electrical signal and converts the first electrical signal into a first digital signal; the digital filter connects the audio processing circuit; the digital filter is also equipped with a data transmission interface, used for connecting an intelligent device and setting up a frequency point through the intelligent device; and the filter filters out the waveband of the first digital signal below the frequency point, and generates a second digital signal and converts into a second electrical signal. By means of the invention, the sound effects can be debugged freely according to the needs of the user, and the filtered waveband position and length can be modulated.

Description

technical field

[0001] The invention relates to the field of audio effect debugging, in particular to an audio system, an audio control method and a mobile terminal with the audio system. Background technique

[0002] At present, smart terminals such as smart phones and tablet computers have become an indispensable part of people's lives, and the functions of smart phones have become more and more powerful. Video, bluetooth, taking photos, surfing the Internet, reading, etc., the functions of smart phones are becoming more and more powerful. At the same time, people have higher and higher requirements for the music playback effect of smart phones. In addition to the certain control of the speaker, there are also certain requirements for the debugging of the mobile phone speaker. The combination of the two can make the speaker play its best role.

[0003] In the prior art, the filtering of the frequency band of the audio system is mainly to set a resistor-capacitor high-pass...
