Abstract: A linear vibration motor comprising a vibrator and a stator, wherein the vibrator comprises at least two permanent magnets disposed adjacent to each other and a magnetic yoke disposed between any two adjacent permanent magnets, and adjacent ends of the two adjacent permanent magnets have the same polarities; the stator comprises coils and magnetic cores disposed in the coils; magnetization directions of the permanent magnets are perpendicular to axis directions of the coils. The linear vibration motor enables the magnetic lines of flux of the permanent magnets to intensively pass through the coils by means of a repulsive force between two ends with same polarity of two permanent magnets so as to obtain a larger magnetic flux and a stronger vibration sensing effect.
