Abstract: An electronic device of various embodiments can include a broadcast receiving module, a connector including a first pin and a second pin, and a processor, wherein the processor can be configured to: identify, through the first pin, the type of external electronic device connected through the connector; drive the broadcast receiving module in a state in which an external antenna included in an external electronic device and the broadcast receiving module are electrically connected through the first pin when the external electronic device corresponds to a designated electronic device type; receive a broadcast signal from the external antenna by using the broadcast receiving module; and output, through the second pin, an audio signal generated on the basis of at least a part of the broadcast signal to a designated device. Other embodiments are also possible.

Abstract: An electronic device includes: a power management module; a connector; a device recognition circuit; and a processor. The processor is configured to: based on a first resistance value detected in a first recognition pin, control the power management module to supply a first power signal to a first power pin and to supply a second power signal to a second recognition pin; receive first identification information of an external device via the first recognition pin or the first data pin; and based on the first identification information, control the power management module to cut off a supply of a first power signal and to maintain a supply of the second power signal.
