ABSTRACT:
A linear vibrator is disclosed. 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, and a plurality of leaf springs, which are interposed between the magnet and the base. Here, the plurality of leaf springs face one another and are coupled to one another Thus, the linear vibrator can increase the range of vibration displacement in a structure and increase the amount of vibration in the linear vibrator. Also, even though the linear vibrator becomes thinner, the range of displacement can be increased because the weight is vibrated horizontally.
