Abstract: A speaker includes a frame, a magnet, a diaphragm, a first coil, and a second coil assembly. The second coil assembly includes at least one second coil group, and each second coil group includes two second coils. The magnet and the diaphragm are mounted on the frame. The first coil and each second coil are coupled to the diaphragm. The first coil is configured to drive the diaphragm to vibrate. The second coil assembly is configured to, when the diaphragm vibrates and a difference between vibration displacements of two vibration regions in the diaphragm that are correspondingly coupled to two second coils in any second coil group exceeds a preset threshold, drive at least one of the two vibration regions to move to reduce the difference between the vibration displacements of the two vibration regions.

Abstract: This application provides a mobile terminal including a first magnet and a second magnet. At least a part of the first magnet and at least a part of the second magnet are disposed in the accommodating space. The first magnet is disposed on a back facet of the display module, the second magnet is disposed on the middle frame, and positions of the first magnet and the second magnet are disposed opposite to each other. The first magnet is a coil, and the second magnet is a main magnet; or the first magnet is a main magnet, and the second magnet is a coil. The main magnet is a Halbach array, and the main magnet generates a unilateral magnetic field on a side opposite to the coil.
