Abstract
A levitation system that allows a mobile terminal to levitate from the bottom using the magnetic levitation principle and to provide a system for levitating a mobile terminal, which enables the mobile terminal to be wirelessly charged in a state in which the mobile terminal levitates, is provided.
Claims18
A system for levitating a mobile terminal, the system comprising:
- a levitation unit mounted on a rear surface of the mobile terminal;
- and
- a levitation module configured to levitate the levitation unit upward,
- wherein the levitation unit includes:
- a mounting case;
- and
- a first permanent magnet placed in the mounting case,
- wherein the levitation module includes:
- a housing;
- a magnet module disposed in the housing to generate a magnetic field for levitating the levitation unit;
- and
- a control unit connected to the magnet module to control a current supplied to the magnet module,
- wherein the magnet module includes:
- a plurality of electromagnets configured to generate a magnetic field for allowing a repulsive force to act on the first permanent magnet;
- and
- a second permanent magnet configured to generate a magnetic field for allowing an attractive force to act on the first permanent magnet, and
- wherein the levitation module is configured to:
- rotate the mobile terminal about a vertical axis if an event is occurred at the mobile terminal in a state that the mobile terminal levitates.
