Abstract

The invention discloses a mobile phone which can play music in the process of conversation, comprising: a central processing unit, a microphone, a communication module and an audio multimedia digital signal encoder / decoder. When the mobile phone is in the process of conversation, the central processing unit accesses the inlet of audio multimedia digital signal encoder / decoder; the microphone accesses another inlet of audio multimedia digital signal encoder / decoder; the output of audio multimedia digital signal encoder / decoder is accessed by the microphone inlet of communication module. The invention also discloses its relative method, comprising: when the mobile phone is in the process of conversation, user can select any stored music document which is encoded by the central processing unit and transmitted to the audio multimedia digital signal encoder / decoder which will send processed music document via communication module; when the receiving end receives the processed signal, user can listen the collected music which is wanted to be shared. The invention can improve the flexibility of mobile phone conversation significantly.

Description

technical field [0001] The invention relates to a mobile phone for playing music during a call and a method thereof. Background technique [0002] The process of playing music on the mobile phone is as follows: the music files stored in the mobile phone are transmitted to the central processing unit (CPU) for decoding, and the obtained pulse code modulation (Pulse Code Modulation, PCM) data is sent to the computer through the digital audio interface. The audio multimedia digital signal codec (audiocodec), and then the differential signal output by the audio codec is directly input to the built-in speaker of the mobile phone for playback. [0003] The process of a mobile phone voice call is: the caller transmits the sound signal input from the microphone to the audio codec, and then the differential signal output by the audio codec is directly input to the microphone input port of the Global System for Mobile Communications (GSM) module, that is, the mobile phone The sound i...
