Vibration generating module, actuator using the same, handheld device, method for generating vibration and recording medium thereof

摘要

The present invention relates to a vibration generating module and an actuator using the same, and relates to an invention for generating vibrations due to shock and inertia by generating negative and positive stiffness using a magnetic field. Elastic means 110 having elasticity for this purpose; Magnetic force generating means 120 for generating a magnetic force; And electromagnetic force generating means for generating an alternating electromagnetic force in accordance with the applied stimulus conversion signal to form a magnetic field, wherein the magnetic force generating means 120 or the electromagnetic force generating means 130 is in one direction according to the stimulus conversion signal. Vibration is generated by moving to a vibration generating module, characterized in that the movement is based on a differential equation.
