1. A linear vibrator, comprising:
- a cover;
a base forming a housing together with the cover, the base defining a bottom wall, a plurality of sidewalls extending vertically from the bottom wall, and a blocking ring extending form a central portion of the bottom wall;
a plurality of elastic members received in the housing, each of the elastic members including a fastening portion connecting to the housing, an elastic arm extending from the fastening portion, and a mounting portion extending from the elastic arm, the elastic arm being deformable parallel to the bottom wall;
a weight suspended in the housing by the elastic members and defining a through hole therein, the weight further defining at least a pair of patches;
a magnet assembly accommodated in the through hole of the weight, a half part of the magnet assembly having magnetic poles opposite to those of the other half, and planes of magnetic poles of the magnet assembly being parallel and facing to the bottom wall of the base; and
a PCB covered by the housing for carrying a coil thereon, the coli being located below the magnet assembly, whereinthe blocking ring contacts the patches during vibration of the combination of the weight and the magnet assembly for protecting the elastic members from plastic deformation.

Abstract
A linear vibrator is disclosed. The linear vibrator includes a housing having a base and a cover, a number of elastic members connected to the housing, a moving unit suspended inside the housing by the elastic members, a PCB covered by the housing and a coil mounted on the PCB. The base has a bottom wall, a plurality of sidewalls extending vertically from the bottom wall and a blocking ring extending form a central portion of the bottom wall. The moving unit has a magnet assembly and at least a pair of patches and vibrates along a direction parallel to the bottom wall, the coil is located right below the magnet assembly.
