Problems solved by technology

[0002] At present, mobile phone MP3 playback technology has been widely used on GSM mobile phones, but its effect is not satisfactory, because the storage space occupied by MP3 files is relatively large, so the storage capacity of mobile phones is very large, and many solutions need to be installed on mobile phones. Add hardware equipment, which increases the cost of the phone

Embodiment Construction

[0031] Such as figure 1 Shown:

[0032] The computer software sends an instruction to check whether it can be imported. If yes, send the MP3 file to the UART port of the mobile phone through the data cable; the mobile phone diagnostic module DIAG detects the serial port data, judges the type of data, obtains the MP3 file, and then interacts with the data management module DM ; The data management module DM and the file system module FS complete the storage of the MP3 files in the flash memory and generate a file list.

[0033] Such as figure 2 Shown:

[0034] The UI receives the user's MP3 playback operation command, sends it to the voice service module, and performs state transfer and other operations according to the status returned by the voice service module; the UI interacts with the data management module to obtain the MP3 file list, and the voice service module VS and the file system module Interactively obtain the MP3 file data in the flash memory; judge and decode...

Abstract

The MP3 playback method for cellphone includes the step of introducting MP3 file and the step of playback of MP3 file. The cellphone PIM software send MP3 file to the serial port of cellphone via data bus; the cellphone diagnosis module detects serial port data to obtain MP3 file before interacting with data management module; and the data management module and the file system module complete the storage of MP3 file in flash memory while creating file list. UI receives the user's MP3 playback command, transmits it to phonetic service module and performs state transfer or other operation based on the return state of the phonetic service module; the phonetic service module and file system module interact to obtain relevant data of MP3 file; and after data diagnosis, decoding and D / A conversion, the sound is sent out in earphone or loudspeaker. The present invention can realize MP3 introducing, storing, playing back and deleting functions in 16 KHz sample rate without affecting the performance of software system in CDMA cellphone.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and more specifically relates to the improvement of the MP3 playing method of the mobile phone. Background technique [0002] At present, mobile phone MP3 playback technology has been widely used on GSM mobile phones, but its effect is not satisfactory, because the storage space occupied by MP3 files is relatively large, so the storage capacity of mobile phones is very large, and many solutions need to be installed on mobile phones. Add hardware equipment, which increases the cost of the phone. [0003] Purpose of the present invention, just be to overcome above-mentioned shortcoming and deficiency, provide a kind of both need not increase hardware cost, can realize the MP3 importing, storing, playing and deleting function of 16KHz sampling rate again, and can not affect the software of existing CDMA mobile phone System and performance of MP3 playback methods. Contents of the inve...
