Abstract
Disclosed is a vibration module for a portable terminal that includes a housing, a magnetic moving part movable in a first direction within the housing; an elastic member supported between the opposite ends of the magnetic moving part and inner walls of the housing, and a solenoid coil provided in the housing. The vibration module is positioned at one end of the moving section by the magnetic force of the magnetic moving part and an object around the magnetic moving part, allowing the vibration module to provide a user with a feeling similar to a click feeling via the acceleration produced at a stopping instant. In addition, when vibrating, the vibration module generates sufficient vibration power through acceleration at the instant of changing moving direction at the ends of the moving section, to provide an alarm function, such as an incoming call notification.
