Abstract
A vibration motor is provided in the present disclosure. The vibration motor includes a stationary part, a vibration part and an elastic connector. The stationary part includes a housing providing an accommodating space. The vibration part is suspended within the accommodating space by the elastic connector. The stationary part comprises a coil, and the vibration part comprises a first magnet set and a second magnet set; the first magnet set and the second magnet set are respectively disposed at two opposite sides of the coil to generate a closed magnetic loop. The first magnet set includes a first left magnet, a first middle magnet and a first right magnet, the second magnet set includes a second left magnet, a second middle magnet and a second right magnet which are opposite to the first left magnet, the first middle magnet and the first right magnet respectively.
