Abstract:
1. An audio transmission line, comprising: an audio transmission plug for being coupled to an electrical device, and having a plurality of signal transmission units for transmitting a plurality of headset signals, each of the signal transmission units transmitting one of the headset signals; and an inline controller coupled to the audio transmission plug through a signal cable, including: a signal input module having a plurality of signal input ends, each of the signal input ends being coupled to one of the signal transmission units in an one-to-one fashion; a signal output module having a plurality of signal output ends; a first control part mechanically linking up at least one first conductive part or one second conductive part, input ends of the first conductive part being coupled to the signal input ends, and output ends of the second conductive part being coupled to the signal output ends; and a plurality of wire circuits, a predetermined pin connection relationship being provided between input ends and output ends of each of the wire circuits, and the predetermined pin connection relationships of different wire circuits being different from one another; wherein the first control part selectively at least controls the output ends of the first conductive part for coupling to the input ends of one of the wire circuits, or controls the input ends of the second conductive part for coupling to the output ends of the same wire circuit.
