1. A haptic feedback system, comprising:
a sensing unit, configured to detect contact with an object;
a haptic feedback module, configured to transfer a contact force to the sensing unit; and
a circuit assembly, electrically connected to the sensing unit and the haptic feedback module,
wherein the haptic feedback module comprises a fixed part, a movable part movably connected to the fixed part, and a driving mechanism electrically connected to the circuit assembly for driving the movable part to move relative to the fixed part,
wherein the sensing unit transmits a sensing signal to the circuit assembly, and the circuit assembly transmits a driving signal to the driving mechanism according to the sensing signal, whereby the movable part is driven to move relative to the fixed part and contacts the sensing unit,
wherein the fixed part has an opening, and when the movable part is driven to move relative to the fixed part, the movable part extends through the opening and contacts the sensing unit,
wherein the fixed part comprises a housing and a base, the housing has a top portion and at least a sidewall connected to the top portion, the opening is formed on the top portion, the base is connected to the housing, and the movable part is disposed between the housing and the base, and
wherein the movable part has at least a stopper protruding toward the housing, and when the movable part moves relative to the fixed part to a limit position, the stopper contacts the top portion to restrict the movable part in the limit position.
