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. By controlling the actuator to generate the vibration signal, the vibration unit with inherent frequency being close to or equal to the frequency of the vibration signal is driven to resonate, thereby realizing local haptic feedback. The vibration units have different inherent frequencies, so the actuator may be controlled to sequentially generate vibration signals with different frequencies to realize local control and switching of the vibrations of the multiple vibration units to obtain different haptic perceptual signals. The present disclosure reduces the size of a touch feedback module and makes a touch feedback device more portable and intelligent.
