WIPO Patent Application WO/2015/182806

Kind Code:

A1

Abstract:

A system for levitating a mobile terminal, according to an exemplary embodiment of the present invention, comprises: a levitation unit mounted on the rear surface of a mobile terminal; and a levitation module that generates an electromagnetic force to make the levitation unit levitate thereabove, wherein the levitation unit includes a mounting case detachably coupled to the rear surface of the mobile terminal and a first permanent magnet seated on the inside of the mounting case, the levitation module includes: a housing; a cover that covers the housing; a magnet module disposed in the housing to form an electromagnetic field for levitating the levitation unit; and a PCB that is connected to the magnet module and includes a control unit that controls a current supplied to the magnet module, and the magnet module includes a plurality of electromagnets that generate an electromagnetic field for making a repulsive force act on the first permanent magnet, and a second permanent magnet that surrounds the exterior of the plurality of electromagnets and generates a magnetic field for making an attractive force act on the first permanent magnet.
