A linear vibration motor includes a fixed portion, a movable portion, and a suspension portion; the fixed portion further includes an outer frame, a coil set, a conductive sheet set, a connecting circuit and a terminal; the movable portion includes a bracket, a primary magnet set, at least a secondary magnet set; the suspension portion includes a pair of elastic members connected to the fixed portion and the movable portion, and provides a restoring force when the movable portion is displaced; the coil set and the primary magnet set provide a driving force to drive the movable portion to generate vibration; the conductive sheet set and the secondary magnet set provide damping when the movable portion moves.
