Design And Implementation Of Mobile Learning System Based On Voice Media

With the development of information technology,a variety of new learning methods are forming. Mobile learning can effectively make use of scattered and fragmented time,which will bring new feelings for learners to learn anytime and anywhere, and improve their knowledge simultaneously. With the wireless bandwidth improvement, the low cost of mobile devices and the demand of mobile learning market, the mobile learning system platform based on Android has great research value and application prospect.According to the actual facts of teachers and students, and the video player software has matered the major share of the domestic market, and the lack of application of voice media, develops and completes a mobile learning system of voice media on account of Android platform, the main contents are as follows:Firstly, this paper introduces the overall architecture, design idea and related technologies of the mobile learning system in view of Android platform.Secondly, develops and completes the mobile learning of media system based on Android platform. Above all, this paper introduces the system development environment,then analyzes the corresponding function of each module, and fullfils the interface and function design. The actual use of Android simulator to test shows that the system can realize classroom audio recording, storage, play and approach voice media information that can be collected and deleted; can lead students to scan the audio-recording on the Internet, download and listen to the teachers’ course of audio-recording, the system interaction is good, and running smoothly.Then, designs the system server which belongs to the mobile learning of voice media on account of the Java Swing technology and the MySQL 5.5 database software. This paper analyzes the functions of the server, explains the overall design concept of the server connection program, and focuses on the design of database of the background management system.Finally, regarding the STM32 as the core, and VS1053 as audio codec, designs a voice recording system which can record all the audio lessons taught by the instructors in real time, introduces the composition of hardware circuit to the recording system briefly, and analyses the software ideas.The test results about the mobile learning system on account of Android platform,whenever and wherever, show that the students can acquire the recording lessons through the system, and also improves the learners’ cognitive level on the course content simultaneously.
