The AUX interface is the audio input interface, which can output audio from electronic audio devices including mp3 (general headphone jack), and listen to the music of these devices with the car stereo.

AUX, which is the abbreviation of "Auxiliary", is a single-wire design for an additional signal line. In general audio equipment, in addition to the formal output and input terminals, there are often several output and input terminals marked with "Aux" as a spare connection terminal. This terminal can be used when you have special applications such as additional sound output or input. Such spare terminals or circuits, regardless of input or output, are collectively referred to as Aux.

The role of AUX, the computer outputs audio to the TV, the computer outputs the audio to the speaker, the mobile phone outputs the audio to the speaker, the MP3 outputs the audio to the speaker, and the network communication-AUX port is an asynchronous port.
