Abstract: An electronic device and a noise control method thereof are provided. The electronic device includes a cable having a first layer forming a first power line and a second layer forming a second power line. The first and second layers are arranged in a vertical stack structure. The cable cancels a magnetic field generated by a current in charging and discharging a battery cell of the electronic device, and removes a noise due to a magnetic field generated from a coil-contained component of the electronic device. Other various embodiments are possible.

Abstract: An electronic device and a method for controlling output through an external output device are provided. The electronic device includes a housing, a receptacle formed so as to receive one of a first external connector and a second external connector, and a circuit electrically coupled to the receptacle. The first external connector includes first, second, third, and fourth terminals. The second external connector includes first, second, third, and fourth terminals. The circuit is configured to detect whether one of the first and second external connectors is inserted into the receptacle, and, based on results of detection, provide an audio output to the first external connector in a first manner if the first external connector is inserted, and provide the audio output to the second external connector in a second manner different from the first manner if the second external connector is inserted.
