In this embodiment, the audio playing message is a message for controlling a plurality of speakers installed in a predetermined place to synchronously play a predetermined audio file. The audio data to be played refers to an audio file to be played specifically.
Specifically, when a plurality of speakers are installed in a field to play audio files synchronously, the total length of the speakers is longer because there is a distance between each speaker and the speakers need to be installed more often if the field is larger. In order to ensure the playing quality of the sound boxes, the sound boxes are transmitted by a UHF (Ultra High Frequency) technology, however, in the transmission process, there is a time delay, the longer the total length of the sound boxes is, the longer the time delay between the sound box closest to the console and the sound box farthest from the console is, and in the actual playing, due to the existence of the time delay, the time for each sound box to play audio is inconsistent, and then the same audio file is played at different times, so that echoes are easily caused when the audio is played, and the experience of listeners is affected.
Therefore, when the audio playing message triggered by the console for controlling the loudspeaker box to work is acquired, the audio data to be played is acquired from the audio playing message.
