A vibration motor is provided, comprising a case having an upper case and a lower case which are coupled to each other; a shaft installed in the case while being supported by the case; a rotor rotatably coupled with the shaft; a stator arranged around the shaft; a first substrate installed on an upper surface of the lower case; and a second substrate coupled to a lower surface of the lower case and electrically connected to the first substrate. The lower case has a first opening and the first substrate is electrically connected to the second substrate through the first opening.

Vibration motor

A flat vibration motor is provided. The flat vibration motor includes a rotor portion, a stator portion, a fixing mount, a pair of terminals, and a base portion. The rotor portion generates vibrating force when rotating. The stator portion houses and couples with the rotor portion to allow the rotor portion to rotate. The fixing mount extends from a side of a lower case of the stator portion. Each terminal includes a contacting portion, an elastic portion, and a joining portion. The base portion forms a plurality of supporting holes through which each of the terminals respectively passes. The joining portion of the terminal connects electrically to the circuit board through a peripheral lower surface around the supporting hole, when the base portion and the fixing mount are coupled.
