Type C耳机包含数字耳机和模拟耳机，数字耳机本质上是一种USB OTG(On-The-Go)设备，当数字耳机连接至终端设备后，终端设备会将该数字耳机识别为OTG设备，在此，终端设备会持续输出5V电压给数字耳机中的IC供电。然而，由于目前IC工艺的进步，数字耳机已不需要5V的供电来实现IC的正常工作，目前终端设备仍然持续输出5V进行供电使得数字耳机工作和待机时消耗多余的电量，导致数字耳机工作和待机时的功耗增加。Type C earphones include digital earphones and analog earphones. Digital earphones are essentially a USB OTG (On-The-Go) device. When a digital earphone is connected to a terminal device, the terminal device will recognize the digital earphone as an OTG device. Therefore, the terminal device will continuously output 5V voltage to supply power to the IC in the digital headset. However, due to the progress of the current IC technology, the digital earphones no longer need 5V power supply to realize the normal operation of the IC. At present, the terminal equipment still continues to output 5V for power supply, so that the digital earphones consume excess power during work and standby, resulting in digital earphones working and Power consumption increases during standby.
