Abstract:
1. An apparatus for providing haptic feedback, comprising: a main board defining a mounting surface; a vibration unit mounted on the mounting surface of the main board, the vibration unit being capable of vibrating along a direction parallel to the mounting surface and defining at least two fastening portions at two distal ends thereof; at least two screws fixing the vibration unit on the main board through the fastening portions along a direction perpendicular to the mounting surface; wherein the vibration unit further comprises a substrate defining a main body, a first piezoelectric layer attached to one side of the main body, and a mass attached to the first piezoelectric layer, each of the main body of the substrate, the piezoelectric layer, and the mass being substantially perpendicular to the mounting surface of the main board; and wherein the substrate further comprises a wing extending perpendicularly from the main body, and the mass further defines a notch for at least partially receiving the wing.
