| description | The utility model relates to the technical field of sound cards, in particular to a multichannel sound card with a monitoring function. The earphone comprises a shell, a circuit board, a control button, an earphone output interface and at least two audio input interfaces, the control circuit board comprises an audio encoding and decoding circuit, a first processor, a second processor, a DAC converter and an earphone output circuit. The control button is connected with the second processor; the second processor processes the button state information from the control button and then sends the processed button state information to the first processor; the audio encoding and decoding circuit is in serial communication connection with the first processor; the first processor processes the digital signal from the audio encoding and decoding circuit according to the signal from the second processor and then sends the digital signal to the input end of the DAC converter; and the output end ofthe DAC converter is conn |
