Abstract
A linear vibrator is disclosed. In accordance with an embodiment of the present invention, the linear vibrator includes a base, a coil unit, which is coupled to the base, a magnet, which is coupled to the coil unit such that the magnet can move relatively with respect to the coil unit, and a leaf spring, which is interposed between the magnet and the base and includes a plurality of plate-shaped members having center portions thereof being separated from one another and both respective ends thereof being coupled to one another. Thus, the linear vibrator can increase the range of displacement in the leaf spring and increase the magnitude of vibration in the linear vibrator.
