摘　　要："扩音效应"产生是突发事件信息传播和情绪传播"共振"的结果,公众探究真相的信息需求和维护社会公义的遍在情绪构成了事件传播与扩散的驱动机制。事件信息质量与隐含的情绪张力决定着事件传播的关键节点的出现、时长、态势等,是决定"扩音"或"消音"的重要变量。突发事件中的信息与情绪传播,遇阻"扩音",顺之则消,发展走向与问题处置的态度、方式、效果等密切相关。信息沟通和情绪安抚的能效,对事件传播"引爆点"是否出现、能否敦促舆情出现"拐点"和最终走向"终点"还是"断点"有决定性影响。Megaphone effect is a result of the resonance between information communication of emergencies and the communication of public emotions. The public's desire for truth and social justice constitutes the drivingmechanism of relevant information diffusion. Event information and implied emotional tension determine the emergence of key nodes and their trends. When information communication and emotional communication in emergencies do not match well,they go opposite ways because trends are closely related to problemsolvings' attitude,means and effects. Information communication and effects of emotional comfort are two important factors. They determine whether the tipping point of the event information can be generated and whether they can urge public opinion to reach an inflection point. And finally they impact whether the emergency goes to the end or reach breakpoints.
