Linear vibrator with an increased driving force
A linear vibrator is disclosed. The linear vibrator in accordance with an embodiment of the present invention includes a base, a coil unit, which is coupled to the base, a magnet assembly, which forms a closed circuit of a magnetic force perpendicular to an electric current flowing through the coil unit and in which the magnet assembly relatively moves with respect to the coil unit, and an elastic member, which elastically supports the magnet assembly. Thus, a linear vibrator with an increased driving force can be provided by preventing the leakage of magnetic flux.
