摘　　要：通过对周期性工作的高分贝喇叭的传导和辐射发射特性进行分析。对其开关电源模块导致的传导和辐射骚扰超标问题进行整改,为涉及开关电源模块的产品的电磁兼容设计和整改提供理论支持。Based on the analysis of the conduction and radiation emission characteristics of the high-decibel horn which operate periodically.The excessive conduction and radiation disturbance problem caused by switching power supply module were rectified,which provide theoretical support for the electromagnetic compatibility design and rectification of products involving switching power supply modules.

关 键 词：传导骚扰 辐射骚扰 共模骚扰 差模骚扰
