According to various embodiments of the disclosure, an electronic device may include a housing, a speaker module disposed inside the housing, a printed circuit board disposed within the housing and including a power transmission line configured to supply power to an electronic component of the electronic device, and a loop line extending from the power transmission line toward the speaker module.

Electronic device including flexible printed circuit board

An electronic device is provided. The electronic device includes a battery, at least one coil, a wireless power transmission/reception circuit electrically coupled to the at least one coil, a charging circuit electrically coupled between the wireless power transmission/reception circuit and the battery, and a processor. The processor may be configured to detect an external electronic device capable of wireless power transmission by using the wireless power transmission/reception circuit), identify a magnitude of power to be received at the external electronic device, control the wireless power transmission/reception circuit to output a first control error packet (CEP) signal having a first power magnitude which is fixed, based on the magnitude of the power being less than a specified power magnitude, and control the wireless power transmission/reception circuit to output a second CEP signal having a variable power magnitude based on the first power magnitude and a second power magnitude, based on the magnitude of the power being equal to or greater than the specified power magnitude.

Electronic device and method of outputting power control signal for wireless power reception in the electronic device
