Software design gradually break the limitation of hardware. All kinds of applications started to adopt multimedia technology so that the software designed is more reasonable and more easier interactive. Software which is able to play nice music and beautiful animation or may do what the people tell to do by the microphone will definitely more popular and more deeply impressed. Multimedia is popular because of its features of visualization and direct viewing. Multimedia programming technology has been becoming mature and now it becomes the focus of modem programming technology. Its development is gradually changing the territory of the use of computer. Instead of only used in office and laboratory as a special product, the multimedia has become the common and popular tools in information age which is extensively used to the management of manufacturing production, School and Education, public information consultation, business and advertisements and military command with training, even penetrate deeply into family life and entertainment. My designed mp3 player implements 3 main functions: firstly,
