Abstract
The present disclosure provides a haptic feedback substrate, a haptic feedback apparatus and a haptic feedback method. The haptic feedback substrate comprises an actuator and a plurality of vibration units connected to the actuator, wherein each vibration unit has a different inherent frequency, the actuator is configured to generate a vibration signal and drive the vibration unit with the inherent frequency being a target inherent frequency to resonate, and a difference between the target inherent frequency and a frequency of the vibration signal is less than or equal to a present threshold.
