Abstract
An electronic device according to an embodiment of the disclosure may include: a battery including an anode having a first length and a cathode having a second length different from the first length, a flexible printed circuit board electrically connected to the battery and surrounding at least part of a side surface of the battery, and a speaker stacked with the battery. The flexible printed circuit board may include a power wiring electrically connected to the anode and a ground wiring electrically connected to the cathode. A first current of a first winding direction generated due to a length difference between the cathode and the anode may flow in the battery, and a second current of a second winding direction opposite to the first winding direction may flow in a wiring disposed closer to the speaker between the power wiring and the ground wiring.
