Abstract

An electronic apparatus having a magnetic switch includes a first body, at least one magnetic component, a second body, and a magnetism barrier. In this case, the first body has at least one space. The magnetic component is accommodated in the space. The second body has at least one magnetizer, which is opposite to the magnetic component. The second body is pivoted on the first body. When the first body and the second body are closed, the magnetic component and the magnetizer face to each other. The magnetism barrier is disposed in the space of the first body. The magnetism barrier is disposed between the first body and the magnetic component.

Claims

1. A portable computer, comprising:

a first body having at least a containing space;

a magnetism barrier case disposed in the containing space;

at least one magnetic component accommodated in the magnetism barrier case;

a second body having at least one magnetizer opposite to the magnetic component and pivoted on the first body;

a metal sheet placed on the side of the magnetism barrier case opposite to the side of the magnetism barrier case facing to the magnetic component so as to block the magnetism leakage of the magnetic component; and

wherein the material of the magnetism barrier case comprises at least one metal and the magnetism barrier case has an opening, when the first body and the second body are closed, the magnetic component and the magnetizer face to each other, one side of the magnetic component which faces to the magnetizer is exposed out of the opening of the magnetism barrier case so that the magnetism barrier case blocks the magnetism of other sides of the magnetic component.

2. The portable computer according to claim 1, wherein the magnetism barrier case is a rectangle case, and the magnetic component is accommodated at the opening.

3. The portable computer according to claim 1, wherein the magnetizer is a flat metal plate.

4. The portable computer according to claim 1, wherein the portable computer is a notebook.

5. The portable computer according to claim 1, wherein the first body comprises an LCD.

6. The portable computer according to claim 1, wherein the second body is a mainframe.

7. The portable computer according to claim 1, wherein the first body is a mainframe.

8. The portable computer according to claim 1, wherein the second body comprises an LCD.

9. The portable computer according to claim 1, wherein the magnetic component is a magnet.

10. The portable computer according to claim 1, wherein the magnetic component is an electro magnet.

11. The portable computer according to claim 1, wherein the magnetizer is a magnet.

12. The portable computer according to claim 1, wherein the magnetizer is made of iron.

13. The portable computer according to claim 1, wherein the magnetizer is an electromagnet.

14. The portable computer according to claim 1, wherein the metal is iron.

15. The portable computer according to claim 1, wherein the metal is iron-platinum alloy.

16. The portable computer according to claim 1, wherein the magnetism barrier case has a space, so as to enhance the magnetism blocking efficiency of the magnetism barrier ease.
