One conductive coil 400.It can be the subregion 20 for first determining and needing to vibrate in vibration, then determining in corresponding subregion 20 need to
The position to be vibrated, and the conductive coil 400 at the position vibrated to the needs is passed through the electric current of variation, and then makes the conductive coil
400, which receive Ampere force, generates vibration.
Further display panel 200 can also include touch module, and touch module is determined for detecting user's operation
User's operation position.Controller responds the operating position that touch-control group determines, makes to the power supply of the conductive coil 400 of user's operation position
The position generates vibration.Touch module can also detect the mode of user's operation, for example, short-press, long-pressing, double-click or sliding
Deng, controller according to user operation mode, the parameter of the electric current of control input conductive coil 400, for example, the frequency of electric current or
The amplitude etc. of electric current.Or the content that controller can currently be shown according to display panel 200, determine present display panel 200
Specified region whether need to vibrate, when the region needs to vibrate, control conductive coil 400 in the region and vibrate.For example,
When terminal is in game mode, vibration and the position vibrated and vibration can be determined the need for by specific scene of game
Parameter etc., and then suitable electric current is inputted to conductive coil 400, to drive display panel 200 to vibrate.
Wherein, when in subregion 20 including multiple conductive coils 400, multiple conductive coils 400 can be the same or different,
The structure and distribution mode of conductive coil 400 in different subregions 20 can be the same or different.It in practical applications, can be with
The structure and arrangement mode of conductive coil 400 are set according to the relative position of conductive coil 400 and magnetic assembly 300, and then reached
The full frame purpose uniformly vibrated.
Conductive coil 400 is for receiving alternating current and generating vibration, and in order to receive alternating current, conductive coil 400 can
To include electric current input line 410 and current output line 420.Electric current enters and leaves one end that line is connected to conductive coil 400, electric current output
Line 420 is connected to the other end of conductive coil 400.It wherein, can be defeated by electric current in order to avoid connecting line and coil windings interfere
Enter line 410 and current output line 420 is set to different layers, and is connected by via hole.Exemplary, electric current input line 410 can be with
It is connected with 400 same layer of conductive coil and with conductive coil 400, current output line 420 is located at the first substrate 211 and buffer layer
