ELECTRONIC APPARATUS FOR SUPPORTING HIGH-SPEED CHARGING AND AUDIO SIGNAL TRANSMISSION/RECEPTION FUNCTIONS

摘要

An electronic apparatus according to various embodiments comprises: a receptacle including a plurality of GND pins, a first CC pin, and a second CC pin and to which a first USB-type plug is insertable; and at least one processor, wherein the at least one processor is configured to: determine whether an external apparatus is connected and the external apparatus supports high-speed charging, by using at least one of the first CC pin and the second CC pin; determine whether the external apparatus supports an audio signal output, by using at least one of the plurality of GND pins, when the external apparatus is determined to support the high-speed charging; and transmit and receive at least one of data or electricity to and from the external apparatus, on the basis of whether the external apparatus supports the high-speed charging and the audio signal output. In addition, other embodiments are possible.
