Abstract: 一种音频播放方法、屏幕发声器件(104, 396)的失效检测方法及电子设备，能够解决屏幕发声器件(104, 396)失效后出现的无声或杂声的问题，从而提高电子设备的可靠性，以及用户体验。其中的音频播放方法包括：接收音频播放指令。其中，音频播放指令用于指示电子设备播放第一音频。响应于接收到音频播放指令，通过屏幕发声器件(104, 396)播放检测音频。在播放检测音频的过程中，获取第一参数。根据第一参数，确定屏幕发声器件(104, 396)是否失效。其中，第一参数为屏幕发声器件(104, 396)的实时负载电流、实时负载电压、实时阻抗和实时导纳中的至少一种。在屏幕发声器件(104, 396)失效的情况下，切换发声器件为扬声器扬声器(370A)，播放第一音频。
