Abstract: The invention discloses a control system and a vibration control method for an LRA. The vibration control method comprises: providing an induction coil, the arrangement and the winding of the induction coil able to obtain an inductive voltage proportional to LRA vibration speed; generating a vibration signal according to inductive voltage and feeding back to a driver connected to the LRA to control the vibration of LRA; wherein the generated vibration signal satisfying the following: when induction voltage is lower than a low-speed threshold, the vibration signal causes the driver to apply a driving force in the same direction; when induction voltage is higher than a high-speed threshold, the vibration signal causes the driver to apply a driving force in the opposite direction; when induction voltage is between the low-speed threshold and the high-speed threshold, the vibration signal does not force the driver to apply force.

Abstract: A linear vibration actuator motor comprises a housing, a coil, a conductive sheet, a bracket, a magnet assembly and two elastic members. The coil is fixed to the bottom wall of the housing. The conductive sheet is fixed to the top wall of the housing and is located above the coil. The bracket is disposed in an accommodating space of the housing, forming framed space, and located above the coil and below the conductive sheet. The magnet assembly is disposed in the framed space above the coil and directly below the conductive sheet. The two elastic members are respectively located between two ends of the bracket and the inner side of two side walls of the housing. Thereby, the invention utilizes the induced current to provide resistance to achieve the damping effect against the motion of the assembly of the bracket and the magnet set with respect to conductive sheet.
