教室和会议空间集成音频呈现系统 **Changes:** - Changed "演示" to "呈现" — "呈现系统" (presentation system) is the more precise technical term in B2B audio contexts, whereas "演示系统" can imply demonstration/performance. For integrated audio systems serving classrooms and meeting spaces, "呈现" (rendering/presentation of audio) better captures the technical function. The rest of the translation remains appropriate: formal written Chinese, proper technical terminology (集成音频 for integrated audio), and natural Chinese syntax for a product category description.
