Claim:
A linear vibrator comprising: a fixed part having an inner space of a predetermined size formed therein; at least one magnet disposed in the inner space and generating magnetic force; a vibration part including a coil disposed to face the magnet to generate electromagnetic force through interaction therewith, and a mass body; a substrate having one end connected to the vibration part to serve as a free end, and the other end connected to the fixed part to serve as a fixed end; and a connection protrusion formed on the fixed part and inserted into a connection hole formed in the substrate so as to allow the substrate to be fixed to the fixed part, wherein the connection protrusion includes an insertion portion placed in the connection hole, wherein the connection protrusion includes a locking portion bent from an end of the insertion portion in an inner diameter direction or an outer diameter direction by a predetermined angle, and protruding outwardly of the connection hole, and wherein the locking portion is wider than the connection hole, to prevent the substrate from being separated from the fixed part.
