1. A virtual haptic assembly, comprising:
a display screen;
an actuator on a light emitting side of the display screen; wherein the actuator comprises a touch panel different from the display screen and at least one piezoelectric sensor, and the touch panel comprises a touch area and a non-touch area arranged on at least one side of the touch area, the piezoelectric sensor is located on a side of the touch panel facing the display screen and located between the display screen and the touch panel, and the piezoelectric sensor is configured to drive the touch panel to vibrate to form haptic feedback in response to interactive information from a user; and
a first cushion, located on the light emitting side of the display screen and fixed between the display screen and the actuator, wherein an orthographic projection of the first cushion on the touch panel is located in the non-touch area.
