Haptic module using magnetic force and electronic apparatuses having the module

Abstract

A haptic module using a magnetic force and an electronic apparatus having the module are disclosed. The haptic module disclosed in the present invention comprises a magnet arrangement frame arranged so that polarities of adjacent magnets are alternate; shielding screens positioned on uppers of each of frame elements of the magnet arrangement frame and formed in a window arrangement to shield any one polarity of the frame elements; linear movement means fixed to outside portions of the shielding screens to move the shielding screens in a longitudinal direction of the frame element; a magnet frame positioned on an upper of the magnet arrangement frame through the shielding screen and taking on the same polarity on the whole of one surface thereof; and a controller that controls the linear movement means. According to the haptic module of the present invention, it is possible to provide various and dynamic force feedback and tactile sensation to a user, as well as reduce complexity of a constitution as compared to a related art and further accomplish miniaturization.
