A linear vibration motor comprises a vibrator and a stator disposed parallel to the vibrator, the vibrator comprising a weight block and a vibration block embedded in the weight block, and the stator comprises stator coils and a magnetic conductive cores disposed in the stator coil, wherein the vibration block comprises at least two magnetic members arranged in a row and magnetic reinforcement members disposed between adjacent magnetic members, and the magnetic members and the magnetic reinforcement members are permanent magnets; adjacent ends of each two adjacent magnetic members have the same polarity; and the magnetization direction of the magnetic reinforcement member is perpendicular to that of the magnetic member. The linear vibration motor can increase the magnetic lines of force passing through the stator coil, thereby intensifying the vibration effect of the product.
