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.
