Abstract:
The application provides a haptic feedback method and apparatus for virtual keys, and an electronic device, and relates to the field of piezoelectric techniques. A touch display panel is controlled to display at least one virtual key, a touch position detected by the touch display panel is acquired, a target waveform parameter is determined according to a positional relationship between the touch position and each region in a target area corresponding to a target virtual key, and a target drive signal is generated according to the target waveform parameter and is sent to a piezoelectric element. The target area corresponding to the target virtual key is divided into multiple regions, and different drive signals are provided to drive the piezoelectric element to vibrate when the fingers of users touch different regions, such that the users may feel the boundary of the virtual key when moving their fingers on the surface of the touch display panel, and the virtual key has more realistic haptic feedback.
