technical field
[0001] The invention relates to the field of electronic technology, in particular to a sound code product and a sound code communication channel circuit. Background technique
[0002] At present, audio connectors (also called audio interfaces) are divided into three-segment audio connectors and four-segment audio connectors, wherein the four-segment audio connectors are further divided into national standard four-segment interfaces and American standard four-segment interfaces. Pin 1 of the national standard four-segment interface (also called interface) is the left channel pin, pin 2 is the right channel pin, pin 3 is the microphone pin, pin 4 is the ground pin, and The pin setting method of the American standard four-segment interface is different. Among them, pin 1 is the left channel pin (also called the left channel interface), and pin 2 is the right channel pin (also called Right channel interface), pin 3 is the ground (GND) pin (also called the ground...
