Method used

[0050] Since the distance between the touch position and the position of the vibrating element is different, even if the vibrating element produces the same vibration, the magnitude of the vibration felt by the user is not the same. In order to enable the user to feel a more accurate vibration, the vibration element can be controlled to send vibrations with different vibration amplitudes according to the distance between the touch position and the position of the vibration element and the pressure, so that the user can feel the vibration more effectively. to the size of the vibration, so that the feedback effect of the method on the pressure is more obvious, that is, compared with the further improvement of the pressure feedback effect.
