Method and apparatus for generating vibration in portable terminal

PURPOSE: A method and a device for generating vibration of a portable terminal are provided to optimally arrange two vibrators on a portable terminal and to control vibration generation. CONSTITUTION: A plurality of vibrators generates vibration to a single vibration direction to a location separated in constant interval on a portable terminal. A control unit(120) determines vibration patterns of a plurality of vibrators according to the control operation about a portable terminal. The control unit drives a plurality of vibrators according to the vibration patterns. A signal vibration direction is up and down direction based on front side of the portable terminal.
