Problems solved by technology

[0005] Obviously, the function of the audio processor (APU) is too single, and the various sound processing processes in the mobile communication terminal are not related to each other, and the sound mixing function cannot be realized.

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0039] as attached figure 2 As shown, an audio processing device 3 based on a portable terminal includes an audio decoder 32, an ADC module 31, a multiplexer (mux1) 33 and a multiplexer (mux2) 34; a sound mixer (Adder1) 35 and sound mixer (Adder2) 36, and a control logic unit 37. ADC module 31 is used for converting the sound from microphone (MIC) into digital signal;

[0040] The audio decoder 32 is controlled by the control unit 1, and is used for decoding various audio data to generate music, and what it outputs is a two-channel music signal. Because the final output is a two-channel sound signal, two sets of sound mixing devices are used, which are respectively composed of multiplexer (mux1) 33, multiplexer (mux2) 34 and sound mixer (Adder1) 35, ...

Abstract

The invention relates to the field of sound broadcasting, disclosing a sound-mixing audio processor and portable terminal, where the portable terminal at least comprises: a control module, a microphone and an audio processor, and the audio processor receives sound signals from the microphone and control module and broadcasts these sound signals after selecting and mixing them. The audio device can selectively superpose digital audio signals to make function-rich sound mixing effect, largely improving the user convenience and interest of the portable terminal.

Description

technical field [0001] The invention relates to the field of sound playback, in particular to an audio processing device and a portable terminal with a sound mixing function. Background technique [0002] With the development of technology, various portable devices with audio processing functions are increasingly popular, such as mobile phones, PDAs, Mp3 players, recording pens, and the like. [0003] However, the functions of existing audio processing chips based on portable devices are usually relatively simple and single. For example, an ordinary voice recorder can only perform simple recording and playback, an Mp3 player can only play built-in music files, and the usual mobile Telephone also can only realize functions such as talking, recording, playing, and can't realize or simultaneously realize rich functions such as mobile phone hands-free, karaoke, sound mixing, and this just makes these portable devices use and lack a lot of fun. [0004] as attached figure 1 As ...
