PURPOSE: A linear vibration motor is provided to improve reliability on impact, thereby securing long service life, preventing malfunctions, and embodying precise vibrations. CONSTITUTION: A spring module(111) casts a circumference of a spring body(20) in which a yoke is combined to a bottom surface in a fixing member(10). The spring body is comprised of a coupling part(22), an inserting part(24), and a connecting part(23). The coupling part combines a yoke in the center. The inserting part is inserted in the fixing member. The connecting part is combined with the inserting part as a spiral shape in the coupling part. The spring body forms a flat surface shape with the coupling part, inserting part, and connecting part on a horizontal line.
