1. A touch device, comprising a touch rendering module, a touch module, a control module, and a driving module, wherein
the touch rendering module is configured for enabling, after a user performs a touch operation, a touch interface to vibrate according to an initial driving voltage;
the touch module is configured for obtaining a touch position and a touch area, and generating a touch signal; and
the control module is configured for determining a changing trend of the touch area according to the touch signal, and generating a driving signal according to the changing trend of the touch area, to adjust the initial driving voltage to be an actual driving voltage,
wherein the control module comprises:
a determination unit, configured for determining the changing trend of the touch area according to the touch signal;
a driving signal generating unit, configured for generating the driving signal according to the determination result of the determination unit, wherein when the determination result is that the changing trend of the touch area is increasing over time, and the touch area increases, the driving signal is generated, to enable the initial driving voltage to increase by a first preset value and be adjusted to be the actual driving voltage; when the determination result is that the changing trend of the touch area is increasing over time, and the touch area decreases, the driving signal is generated, to enable the initial driving voltage to decrease by a second preset value and be adjusted to be the actual driving voltage.
