Description

Technical Field

[0001] The utility model relates to the technical field of audio connection, in particular to a pin structure for an audio connector. Background Art

[0002] The pins used in audio connectors generally refer to the pin output ports. Ordinary single-ended output is divided into three lines: left channel, right channel and ground line, while balanced output is divided into four lines: left channel positive pole, left channel negative pole, right channel positive pole and right channel negative pole. In single-ended output, since the signals of the left and right channels will flow to the same ground line, the signals of the left and right channels will interfere with each other, resulting in insufficient separation. In balanced output, since the signals of the left and right channels do not need to pass through the common ground line, the disadvantages of single-ended output are eliminated and a very good separation is achieved.
