Claim 0:
1. A single audio interface signal switching circuit, comprising:
a single audio receptacle;
an audio signal output module, one end of the audio signal output module electrically connected to the single audio receptacle;
a time code input module, one end of the time code input module electrically connected to the single audio receptacle;
a time code output module, one end of the time code output module electrically connected to the single audio receptacle;
a driver chip, the driver chip including a plurality of pins, wherein another ends of the audio signal output module, the time code input module, and the time code output module are respectively electrically connected with each different pin of the driver chip; and
a working mode switching module, the working mode switching module electrically connected to one pin of the driver chip;
wherein the working mode switching module is used to control the driver chip to generate a drive signal to control working states of the audio signal output module, the time code input module, and the time code output module.
