PURPOSE: A speaker and electronic equipment are provided to perform additional functions using electricity which is generated from an electromagnetic inductor. CONSTITUTION: A speaker(100) comprises a housing(110), a magnet(120), vibratory elements(130), and an electromagnetic inductor(140). The vibratory elements are arranged in the housing to vibrate against a magnet and generate a sound. The electromagnetic inductor is arranged on the vibratory elements to induce the magnetic field of the magnet and generate electricity. The vibratory elements vibrate against the magnet. The electromagnetic inductor is driven on the vibratory elements. The electromagnetic inductor generates the electricity by inducing the intensity of the magnetic field and the direction change of the magnet. |
