Abstract
A linear vibration motor includes a base including an accommodation space; a vibration unit; and a first elastic unit suspending the vibration unit in the accommodation space. The first elastic unit includes two elastic pieces located on two opposite sides of the vibration unit, each the elastic piece having a main elastic arm, a first auxiliary elastic arm and a second auxiliary elastic arm extending reversely in a bending way respectively from an end of the first auxiliary elastic arm and an end of the second auxiliary elastic arm. The main elastic arm is perpendicular to the vibration direction, the first auxiliary elastic arm and the second auxiliary elastic arm are respectively located on the two opposite sides of the main elastic arm, the first fixed arm is fixed to the vibration unit, and the second fixed arm is fixed to the base.
