FLAT TYPE OSCILLATION MOTOR

摘要

PURPOSE: A flat type oscillation motor is provided to prevent an eccentric amount from being reduced, reduce a number of production processes and improve oscillation performance of a thin motor. CONSTITUTION: A shaft connects a lower bracket and an upper case. An oscillation motor is supported by the shaft and rotated. An upper substrate(60) is circular shaped. A pair of coils(80) are distanced from each other at uniform angles on a surface of the upper substrate. A counter weight(100) is arranged on other side of the upper substrate corresponding to the coils. The flat type oscillation motor is integrally formed by an insulating material which is filled between the coils and the counter weight. The counter weight is formed at 90 degrees. Since the upper substrate(60) has a simple structure and coils which are arranged on the upper substrate(60) are corresponding to the counter weight(100), a number of manufacturing processes is reduced and productivity is increased.
