For example, in a terminal with a Type-C interface, an adapter can be connected to the Type-C interface, and an audio device plug can be further connected to the adapter.
However, when the Audio device plug is pulled out of the adapter, the GND pin of the Audio device contacts the elastic piece connected to the MIC pin in the Audio jack interface in the adapter. The current mode for controlling the power failure of the MIC pin is that a power management chip of a terminal detects whether the CC pin of a Type-C interface of the terminal is powered off or not, and then transmits a control signal to a power supply control module under the condition that the CC pin is powered off, so that the power supply control module controls the power failure of the MIC pin, wherein the signal needs to be transmitted to the power management chip firstly, then the power management chip transmits the signal to the power supply control module, and then the power supply control module executes control operation.
The whole flow is consuming time more, and when being difficult to guarantee that the audio equipment plug is pulled out from the adapter, the MIC pin is cut off the power supply immediately. Therefore, the GND pin of the audio device may contact the elastic piece connected to the MIC pin, and the MIC pin is not powered off, so that current flows into the GND pin of the audio device, which causes the audio device to output POP sound, thereby reducing user experience.
