Claim 6:
7. A force sensing module with vibration feedback, comprising:
a substrate, having a touch operation surface and a mounting surface on opposite sides;
a frame, disposed with at least three buffer spacers, the buffer spacers connecting the frame to the substrate;
at least one tactile actuator, each tactile actuator further comprising a magnet set and a coil set, one of the magnet set and the coil set being disposed on the substrate, the other of the magnet set and the coil set being disposed on the frame; and
a plurality of magnetic sensors, each magnetic sensor further comprising a Hall element, the Hall element being disposed at the substrate or the frame where the coil set is located, the position of the Hall element corresponding to the magnet set and spaced by a gap in a vertical direction; when a force applied to the touch operation surface causes the substrate to generate an offset and the magnet set to approach the Hall element, the Hall element outputting a force signal representing a voltage change caused by the approaching magnet set;
wherein the magnetic sensor and the tactile actuator are located adjacent to a corresponding buffer spacer with a gap in a lateral direction between the magnetic sensor and the corresponding buffer spacer.
