Abstract: The present invention relates to the technical field of electronic products, and provides a linear vibration motor. The linear vibration motor comprises a motor housing, a stator, a vibrator, and two elastic supports for suspending the vibrator within the motor housing, for supporting the vibrator and for providing elastic restoring forces, wherein the elastic supports are located at two ends of the vibrator in a vibration direction respectively. Each of the elastic supports is made up of a plurality of elastic sheets whose one ends are fixedly connected in sequence, which are arranged side by side and which have C-shaped openings respectively. Each of the elastic supports comprises a first connection point fixedly connected to the vibrator and a second connection point fixedly connected to the inner wall of the motor housing. Therefore, the polarization phenomenon of a vibration block is reduced when the vibration feedback to a user's touch operation is realized, the noise is reduced, and the stability and the reliability of the entire linear vibration motor are improved.
