The multi-channel surround system used for multimedia teaching can bring more powerful auditory effects to the audience, and can fully mobilize students’ interest and enthusiasm in learning. Such as music arrangement, Yunnan musical instruments, the sound characteristics of national music and national musical instruments, and the sound processing knowledge of music processing. You can quickly master basic music arrangement, the sound characteristics of musical instruments, and the knowledge of mixing and processing music. Achieve better teaching results. Most multimedia devices on the market, with the music and sound effects, a high compression mono or stereo transmission. This mono or stereo transmission with a high compression ratio is very low quality. Since audio is far less powerful than visual impact, and the capacity of the disc used to store audio is small, people tend to focus on visual information processing, but ignore the importance of audio. Multi-channel surround sound technology has received more and more attention in the teaching practice of film and television colleges, but it is also affected by various factors such as venue facilities. This has caused bottlenecks in teaching in this field and has greatly affected the teaching effect. This paper designs and constructs a mobile multi-channel surround sound teaching system from a practical perspective. As part of a multimedia teaching device, try to use the best digital surround sound system for today’s audio reproduction. The feasibility of entering the digital surround sound system into the multimedia teaching classroom is analyzed. Better promote students’ correct understanding of audio and use modern high-tech digital technology to spread real art.

用于多媒体教学的多声道环绕系统可以为听众带来更强大的听觉效果，并可以充分调动学生的学习兴趣和热情。如音乐编曲，云南乐器，民族音乐和民族乐器的声音特性以及音乐处理的声音处理知识。您可以快速掌握基本的音乐编曲，乐器的声音特性以及混音和处理音乐的知识。取得更好的教学效果。市场上大多数多媒体设备，具有音乐和声音效果，高压缩率的单声道或立体声传输。具有高压缩比的单声道或立体声传输的质量非常低。由于音频远没有视觉冲击那么强大，而且用于存储音频的光盘容量很小，人们倾向于专注于视觉信息处理，却忽略了音频的重要性。在影视学院的教学实践中，多声道环绕声技术越来越受到人们的关注，但是它也受到场地设施等各种因素的影响。这导致该领域的教学瓶颈，并极大地影响了教学效果。本文从实际的角度设计并构建了一个移动多声道环绕声教学系统。作为多媒体教学设备的一部分，请尝试使用最佳的数字环绕声系统进行当今的音频再现。分析了将数字环绕声系统输入多媒体教学教室的可行性。
