Abstract

Provided is multi-direction input device. The multi-direction input device includes a magnet part, a manipulation member configured to receive the magnet part, the manipulation member being moved in multi-directions by user'"'"'s manipulation, and a hinge part configured to surround at least one side of the manipulation member, the hinge part allowing the manipulation member to return to an original position by elasticity. At least one portion of the manipulation member is formed of a magnetic field blocking material.

Claims

1. A multi-direction input device comprising:

a magnet part;

a manipulation member configured to receive the magnet part, the manipulation member being moved in multi-directions by user'"'"'s manipulation; and

a hinge part configured to surround at least one side of the manipulation member, the hinge part allowing the manipulation member to return to an original position by elasticity,

wherein at least one portion of the manipulation member is formed of a magnetic field blocking material.

2. The multi-direction input device of claim 1, wherein the manipulation member comprises:

a cap part disposed in an inner space of the manipulation member to receive the magnet part; and

a flat plate part extending outward from one area of the cap part.

3. The multi-direction input device of claim 2, wherein a button part is coupled to an upper end of the cap part above the flat plate part, and the hinge part is coupled to a lower end of the cap part under the flat plate part.

4. The multi-direction input device of claim 2, wherein, in the manipulation member, the cap part is formed of the magnetic field blocking material, the cap part and the flat plate part are formed of the magnetic field blocking material, or the magnetic field blocking material is disposed on the inside of the cap part contacting the magnet part.

5. The multi-direction input device of claim 4, wherein the magnetic field blocking material is formed of at least one of a metal, a ceramic, and a rubber which have magnetic permeability of approximately 200 or more.

6. The multi-direction input device of claim 3, further comprising a fixing part extending from the lower end of the cap toward the flat plate part to prevent the hinge part from being separated.

7. The multi-direction input device of claim 1, further comprising:

a case part comprising upper and lower cases coupled to each other to receive the hinge part and the manipulation member therein, and

a protrusion protruding upward from the outside of the lower case to fix the outside of the hinge part.

8. The multi-direction input device of claim 1, further comprising an actuator and a dome switch disposed under the magnet part,

wherein the actuator contacts a top surface of the dome switch to adhere to the dome switch through an adhesion unit.

9. The multi-direction input device of claim 8, wherein the adhesion unit comprises a Teflon tape configured to cover the actuator and the whole dome switch.
