Abstract
There is provided a flat type vibration motor 100 that includes a bracket 150 with a shaft 140 of which one end is inserted into and fixed to the center thereof, a printed circuit board 110 having a terminal portion 130 receiving external electricity and disposed on the side of the bracket 150, a stator disposed on the top of the printed circuit board 110, a rotor 170 rotatably installed in the shaft 140 and generating vibration while rotating by interaction with the stator 160, and a stopper 180 installed at the other end of the shaft 140. The bracket 150 and the shaft 140 are electrically connected with the terminal portion 130. Further, it is possible to use the bracket or a shaft as an external power connection terminal by electrically connecting a negative terminal to the bracket and the shaft through the contact portion.
