PURPOSE: A linear oscillation motor and a manufacturing method thereof are provided to improve vibration force by uniting a permanent magnet with a heavy body and adding weigh and to form a strong line of magnetic force. CONSTITUTION: Top and bottom casings(10,20) are used in order to protect each element. A PCB(Printed Circuit Board)(30) is arranged in the floor of the bottom casing. The PCB applies power in a coil(50). The PCB controls the power applied in the coil in order to repetitively change the polarity of an electromagnet member(40). The coil is reeled on the outer circumference of the electromagnet member. The electromagnet member is electrically magnetized by the coil. A spring(60) elastically supports a heavy body(70). The heavy body generates vibrations in the bottom surface of the spring. A permanent magnet(80) is formed into a ring or doughnut shape.
