Abstract
An electronic device includes a housing structure including a first cover facing in a first direction and forming a first surface of the electronic device, and a second cover facing in a second direction opposite to the first direction and forming a second surface of the electronic device. The electronic device also includes a display positioned in a space formed by the housing structure and exposed through the first surface. The electronic device further includes an energy harvesting structure positioned in the space and configured to generate a current from a contact input to the first surface and a sound input generated inside and outside the electronic device. The electronic device additionally includes a battery positioned in the space. The electronic device also includes a charging circuit configured to charge the battery using the current received from the energy harvesting structure.
