Flat type vibration motor |
摘要 |
A flat type vibration motor provides a weight on a round shaped upper substrate and a portion corresponding to a winding coil arranged at one side of the upper substrate to prevent the eccentric amount from being reduced due to a slim thickness of a rotor, thereby facilitating a slim size of the motor. The flat type vibration motor includes: a lower case; an upper case which covers an upper portion of the lower case; a shaft which connects the center of the lower case with the center of the upper case and supports them; a lower substrate attached to one portion on an upper side of the lower case; a magnet attached to the lower substrate and the upper side of the lower case; a round shaped thin upper substrate rotatably supported in the shaft; a commutator provided with a plurality of segments on the circumference of the center of the shaft at the bottom of the upper substrate; a pair of brushes of which one end is fixed to the lower substrate and other end is in contact with the commutator to be electrically connected with the commutator; a pair of winding coils arranged separated from each other at a constant angle toward one side of the upper substrate; a weight of high specific gravity arranged toward the other end of the upper substrate corresponding to the winding coil; and an insulator of resin filled between the winding coils and the weight, for firmly fixing the winding coils and the weight to the upper substrate.
