The Design And Implementation Of Audio-book Based On Smart Phone

Since 21 th Century,information technology has entered into a high speed development stage.More and more people use a mobile device to surf on Internet instead of a personal computer.As the result of the development of the fourth generation mobile communication network in China,a large amount of consumers enjoy services provided by mobile network.Mobile applicationsfor audio books emerge at this historic moment and it becomes a positive supplement of the traditional reading methods.According to the statistics of 2010 China Mobile Internet usage,mobile-reading has become the third most popular application after mobile-game and mobile-music.There are several mobile audio reading applications both on iOS and Android.While these applications are relevant to operating system of the mobile phones which makes the development of this kind of software difficulty.As the development of mobile Internet and the transformation of people's reading method,a platform with system independent is necessary to enjoy reading.In order to solve this problem,we developed a mobile-based audio books system,woReading.This system is an application based on Web/Wap architecture,i.e.its background is implemented based on traditional web technical,and its front end is based on wap.This system is based on traditional Linux Nginx MySQL PHP(LNMP)and Brower/Server website framework.System mangers access to system back end through a WEB liked way.To ensure system security,backend creates relative directories according to the authority of different roles;on the other hand,users skipping and listening audio books in a WAP way.woReading was consists of 11 main function modules: system module,audio program processing module,column management module,program work flow module,manage module,market module,product and price fixing module,search module,play and download module,audio paly module and background management module.A detail introduction of PHP,MySQL and nginx from three aspects is presented in chpater 1.Then,chapter 2 gives an evaluation of the audiobook system and the key technology from the angle of software engineering,including the format of audiobook,functional requirements,and schedule arrangement and so on.After that,the involved database design and key technologies such as large file upload,system log,user authority management are described in detail.Finally,this paper introduces the application of this system and gives some prospects about future work.woRead audio book system has already been online and has been highly acclaimed by users.
