A vertical vibrator is provided to improve a reaction speed by preventing minute vibration of a vibration part through a property of a plate spring. A bottom housing(10) has a receiving space. A top housing(20) is coupled with a bottom housing by an interference fit. A coil(30) is coupled in the top housing. A vibration part(40) includes a vibrator, a yoke, an external magnet, and an internal magnet. A coupling part is formed in a bottom part of the yoke. The external magnet has an external plate. The internal magnet has an internal plate. A spring part(50) includes a plate spring and a damper. A coupling groove is formed in the plate spring. A coupling part of the yoke is coupled in the coupling groove. The damper is coupled in an outer circumference of the plate spring.
