The present invention relates to a linear vibration motor which provides a structure that improves electromagnetic force by inserting a magnetic piece of different materials into a non-magnetic or a weakly magnetic bracket positioned on a bottom surface of a coil, and more specifically to a linear vibration motor in which, as a bracket component is manufactured as a single component including the magnetic piece of different materials during the manufacture of the bracket component, the magnetic piece of different materials can concentrate electromagnetic force without forcibly pulling down a driving unit which drives horizontally and linearly, and in which, when the driving unit stops the linear driving, the magnetic piece of different materials can shorten a driving stop time of the driving unit. The linear vibration generating apparatus of the present invention, having the above-described configuration, can be easily manufactured by press-fitting into the bracket by using a press and ...
