Abstract
Disclosed is a haptic feedback device used in an electronic device for providing haptic feedback. The haptic feedback device includes an electronic board defining at least two supporting elements and a receiving cavity, a piezoelectric vibrator coupling to the supporting elements and at least partially received in the receiving cavity. The piezoelectric vibrator is capable of vibrating along a direction parallel to the electronic board. At least two bolts are provided to fix the piezoelectric vibrator on the electronic board through the supporting element along a direction parallel to the electronic board.
