Abstract
A haptic feedback apparatus includes a screen and a piezoelectric vibrator partially connected with the screen. The screen comprises a display viewing area and a frame surrounding the display viewing area. The piezoelectric vibrator engaged with the screen defines a moving portion having a projecting portion extending from one distal end of the moving portion toward the screen. Wherein, the screen defines a cavity and the projecting portion of the piezoelectric vibrator is at least partially accommodated in the cavity. The manufacture of the haptic feedback apparatus is simple and low-cost.
