Apparatus Using Spring based on Reaction upon External Force for Providing Passive Haptic Feedback, Module Providing Passive Haptic Feedback Using the Same, Portable Unit Using the Same and Control Method therewith
The present invention relates to an external force response haptic providing device using a spring, a haptic providing module using the same, a portable terminal using the same and a control method thereof. The configuration of the present invention is to form an appearance and the housing having a receiving space therein; A pressing plate provided at an upper portion of the housing and acting on an external force; First magnetic force generating means connected to the lower part of the pressing plate and reciprocating in one direction in the housing according to the strength of the external force and generating magnetic force; A spring provided between the pressing plate and the first magnetic force generating means to provide an elastic force to the pressing plate and to generate an electrical signal by electromagnetic induction according to the reciprocation of the first magnetic force generating means; A second magnetic force generating means provided inside the housing to generate magnetic force so that the first magnetic force generating means and the attraction force or the repulsive force can act; Measuring means connected to the spring and receiving the generated electrical signal to measure the strength of the external force; And control means connected to the measuring means and the first and second magnetic force generating means to control the power supplied to the first and second magnetic force generating means, the control means being based on the strength of the external force. The haptic feedback is provided to the user by adjusting the attraction force or the repulsive force acting between the second magnetic force generating means.;Electromagnetic Induction, Spring, Force Sensor, Input Device, Vibration Haptic, Stiffness Device
