Abstract
A vibration motor is disclosed. In accordance with an embodiment of the present invention, the vibration motor includes a base, a vibrator, which reciprocates in the base, a protruding part, which is formed on at least one of the base and the vibrator, and an elastic body, which is interposed between the base and the vibrator and has a through-part formed therein and in which the protruding part is inserted into the through-part and the elastic body is coupled to the base or the vibrator by caulking or bending the protruding part which is protruded through the through-part. Thus, the vibration motor can have a uniform resonant frequency characteristic since a spring is coupled by way of caulking or bending.
