Abstract
Embodiments in the present disclosure provide a vibration panel and a drive method therefor, and a haptic feedback device. The vibration panel includes: a substrate; a piezoelectric sensor located on one side of the substrate, where the piezoelectric sensor driven by an excitation signal is configured to vibrate, and to drive the substrate to vibrate; and a regulation structure, where the regulation structure is configured to regulate a characteristic frequency of the substrate, so as to make a resonant frequency of the substrate satisfy a preset range.
