PURPOSE: A bar type vibrating motor is provided to maximize electromagnet force by reducing an opening through a yoke on a line of magnetic force between a coil and a permanent magnet. CONSTITUTION: The side of a case(101) is opened. A permanent magnet(102) is combined with the inside of the case. A coil(106) generates electromagnet force while maintaining a fixed space on the outside of the permanent magnet. A yoke(107) is combined with the outside of the coil to become a path of the electromagnet force generated in the permanent magnet. A weight(110) is combined with the yoke to induce an eccentricity. A brush assembly(114) is combined with a commutator assembly. A shaft is combined with the weight. The commutator assembly is combined with the shaft and the weight. A fixing sill is formed in the case. The weight includes a yoke combination groove and a shaft groove. |
