摘　　要：某蓝牙音柱进行CE认证时不满足EN 55013和EN 55022对辐射发射与骚扰功率的要求,且超标严重。针对音响开关电源的EMI问题,采取了在相关位置添加不同的瓷片电容、套磁珠、变更Y电容位置等整改措施,整改后,蓝牙音柱的EMI测试结果满足标准要求。One Bluetooth sound bar could not meet the requirements of radiated emission and disturbance power in EN 55013 and EN 55022 for CE certification. It exceeded the limits severely. According to the EMI problems of the switching power supply of the sound bar the countermeasures are adopted by adding ceramic capacitors and ferrite beads and changing the position of Y capacitor. After the rectification, the sound bar could pass the tests.
