Abstract: A force sensing module with vibration feedback is disclosed, comprising: a substrate, a frame and a plurality of magnetic sensors; the substrate is disposed with at least one tactile actuator, and the substrate has a touch operation surface and a mounting surface on opposite sides, the tactile actuator is mounted on the mounting surface; the frame is disposed with at least three buffer spacers, the buffer spacers connect the frame to the substrate; the magnetic sensor includes a magnet and a Hall element, one of the magnet and the Hall element is disposed on the frame, and the other is disposed on the substrate; thereby when a force is applied on the touch operation surface to make the substrate offset, the Hall element output a force signal due to the voltage change caused by approaching magnet, and the signal drives the tactile actuator to generate a vibration feedback.

Abstract: The invention discloses a control system for LRA, applicable to an LRA having a speed sensing coil. The control system comprises a signal amplifier, an excitation device, a flow controller, a processing unit, and a driver. The processing unit is connected to the signal amplifier, the excitation device and the flow controller, so as to stop output, output the excitation signal as a driving signal or process the induction signal from the signal amplifier into an appropriate system damping coefficient and output as a driving signal when the flow controller outputs a stop, excitation or braking state signal, respectively.
