Summary:The invention discloses a vibration device, which comprises a shell, a magnet structure and a coil assembly, and is characterized in that the magnet structure is mounted in the shell and comprises a first magnet structure and a second magnet structure which are oppositely arranged in a first direction; a magnetic field formed by the first magnet structure is at least distributed in a second direction, and a magnetic field formed by the second magnet structure is at least distributed in a third direction; the coil assembly comprises a coil which is installed in the shell and located between the first magnet structure and the second magnet structure. Wherein one of the magnet structure and the coil assembly is arranged to be a vibration piece, the vibration piece is connected to the shell through an elastic piece, and the elastic piece is arranged to elastically move in two vibration directions, so that when the coil is electrified with alternating current, the vibration piece vibrates in the two vibration dire
