Linear vibration motor

The invention relates to a linear vibration motor, which includes an enclosure, a vibrator component, a stator component and two metal elastic pieces. The enclosure has a housing space, the vibrator component is located on the stator component, the metal elastic pieces support the vibrator component in the housing space in a suspending manner, the linear vibration motor also includes two pieces ofdamping foams fixed in the housing space, a lower surface of the vibration component is provided with two lower convex parts spaced from the damping foam at left and right sides, the damping foam canhit the lower convex parts when the vibrator component vibrates, reverse rigidity (the tendency of hindering motion of the vibrator component) is provided, an effect of protecting the metal elastic pieces is realized, the service lives of the metal elastic pieces are prolonged, damage of the metal elastic pieces under fierce impact is prevented, and the damping foam performs up-down limiting of the vibration component at
