1. A vibration generating device, comprising:
- a housing including an inner space;
a shaft provided in the inner space of the housing in an axial direction;
a frame including a shaft hole into which the shaft is inserted;
a bearing member mounted on the frame to be vibrated in a state of contact with the shaft;
a vibrating part mounted on an outer surface of the frame and including a magnetic field generation part;
elastic members mounted on both ends of the vibrating part or the bearing member in the axial direction; and
a coil provided in the inner space and vibrating the vibrating part by interaction with the magnetic field generation part.
