摘　　要：汽车喇叭是车辆安全行驶必不可缺少的器件,在喇叭工作时,会因为动静触点的反复闭合,产生各种频率的干扰杂波。通过喇叭的正极和负极线,对车辆的电源和搭铁造成干扰。针对实际中喇叭干扰产生的问题进行分析定位,提出在整车上可行的解决方案,并进行整车上的验证试验。As a important electrical component in driving car safely, the auto horn is absolutely necessary. It will produce interference noise by dynamic contact and static contact collide each other when auto horn on working.The noise will cause negative interference to the vehicle power supply and grounding by positive line and negative line from horn. Contrapose the issue generate by auto horn, that interference with other electrical component,through analyzing and positioning, put forward the feasible solution and carry out validation tests on the vehicle.
