A vibration actuator module is disclosed. In accordance with an embodiment of the present invention, the vibration actuator module includes a vibrated body, a vibrating plate, which is coupled to the vibrated body and has a smaller elastic modulus than the vibrated body, and a driver, which is coupled to the vibrating plate.

A linear vibrator is disclosed. The linear vibrator in accordance with an embodiment of the present invention includes a base, a coil unit, which is coupled to the base, a magnet assembly, which forms a closed circuit of a magnetic force perpendicular to an electric current flowing through the coil unit and in which the magnet assembly relatively moves with respect to the coil unit, and an elastic member, which elastically supports the magnet assembly. Thus, a linear vibrator with an increased driving force can be provided by preventing the leakage of magnetic flux.

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.
