1. A vibration apparatus, comprising:
a substrate abutting on a display panel of a mobile terminal, wherein the substrate is parallel to the display panel;
at least two coils fixed on an inner side surface of the substrate, wherein the inner side surface faces away from the display panel, the at least two coils are disposed coaxially, and axes of the at least two coils are perpendicular to the substrate;
an elastic piece, wherein a first side surface of the elastic piece abuts on the inner side surface of the substrate; and
a magnetic component connected to a second side surface of the elastic piece, wherein the magnetic component comprises an accommodating groove, and the at least two coils are at least in part accommodated in the accommodating groove, wherein
the second side surface is disposed away from the first side surface, the vibration apparatus has at least a first working mode and a second working mode, and numbers of coils electrified when the vibration apparatus is in the first working mode is not equal to numbers of coils electrified when the vibration apparatus is in the second working mode.
