Vibration apparatus, mobile terminal and method for controlling the mobile terminal

A mobile terminal, comprising a display panel and a vibration apparatus, wherein the vibration apparatus comprises:

• a substrate abutting, 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;
• and
• the substrate of the vibration apparatus abuts on an inner side of the display panel.

A method for controlling a mobile terminal, applied to a mobile terminal, wherein the mobile terminal comprises a display panel and a vibration apparatus, the vibration apparatus comprises:

• a substrate abutting on the display panel, 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;
• and
• the method comprises:
• when it is detected that the mobile terminal is in the first working mode, controlling a first quantity of coils in the at least two coils of the vibration apparatus to be in an electrified state, so that the vibration apparatus works as a sound generator;
• and
• when it is detected that the mobile terminal is in the second working mode, controlling a second quantity of coils in the at least two coils of the vibration apparatus to be in the electrified state, so that the vibration apparatus works as a motor, wherein
• the first quantity is not equal to the second quantity.
