Abstract
A haptic feedback device includes a screen and a piezoelectric vibrator partially connected with the screen. The screen includes 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 toward the screen. The screen defines a cavity and the projecting portion of the piezoelectric vibrator is at least partially accommodated in the cavity.
