Abstract

An electronic device includes a jack electrically connecting an outer speaker, a power controller, an audio generator electrically connecting the jack and the power controller, and an inner speaker. The inner speaker includes a housing, a magnet, a vibrating element, and a first electromagnetic inducting coil. The magnet and the vibrating element are configured in the housing. The vibrating element electrically connects the audio generator via the jack to be vibrated relatively to the magnet for sounding. The first electromagnetic inducting coil is configured on the vibrating element and electrically connected to the power controller to generate electricity induced by a magnetic field of the magnet. A power storage is charged by the electricity via the power controller. Through the jack and the power controller, the power storage is charged by electricity generated by a second electromagnetic inducting coil of the outer speaker.
