播放背景音乐时，每个音箱负载的输入状态通常不一样，有的处于低音量状态。其中有些是关闭的，但在紧急广播的情况下，每个扬声器的输入状态都会改为大音量状态，即通过遥控指令强制切换音量。
When playing background music, the input state of each speaker's load is usually different, with some in a low volume state. Some of them are turned off, but in the event of an emergency broadcast, the input state of each speaker will be changed to a high volume state, which is forced to switch the volume through remote control commands.
