An electronic device and a speaker are provided. The speaker includes a housing, a magnet, a vibrating element, a circuit board and a electromagnetic inductor. The magnet is disposed in the housing. The vibrating element is disposed in the housing to vibrate relatively to the magnet for sounding. The electromagnetic inductor is disposed on the vibrating element for inducting a magnetic field of the magnet to generate electricity. The circuit board is disposed at the housing and has two audio input terminals, two audio output terminals, two power input terminals and two power output terminals. The audio input terminals are electrically connected to the audio output terminals, respectively. The power input terminals are electrically connected to the power output terminals, respectively. The vibrating element is electrically connected to the audio output terminals. The electromagnetic inductor is electrically connected to the power input terminals. |
