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.

Abstract: Disclosed is a vibration motor for a portable terminal, including a flat spring; a cylindrical magnetic substance mounted on the flat spring; an annular magnetic substance disposed around the cylindrical magnetic substance mounted on the flat spring; and a coil disposed between the cylindrical magnetic substance and the annular magnetic substance, wherein the magnetic substances perform a linear reciprocal movement by the electromagnetic force generated between the magnetic substances and the coil and by the elastic force of the flat spring as an electric current is applied to the coil. The vibration motor operates at higher resonant frequencies than those of conventional vibration motors, thereby improving the sense of an after-vibration and realizing a delicate haptic feedback function.
