Abstract

An anti-electromagnetic wave box for a mobile phone is composed of a first housing and a second housing for receiving a mobile phone therein. The first and second housing are processed with anti-electromagnetic treatment for shielding a user from electromagnetic waves generated by the mobile phone. The first housing has a non-shielded area for covering an aerial of the mobile phone sending and receiving signals. The second housing has a sound hole defined at an upper portion thereof to enable sound waves to transmit out therefrom. A key cover is formed at a lower portion of the second housing for accessibility of a keyboard of the mobile phone. A window is defined between the sound hole and the key cover for visibility of a screen of the mobile phone. Each of the sound hole, the key cover and the window is processed with anti-electromagnetic treatment.

Claims

1. An anti-electromagnetic wave box for a mobile phone, the box comprising:

a first housing (10) and a second housing (20) pivotally connected with each other at first sides thereof for receiving a mobile phone therein, wherein

the first housing (10) having a non-shielded area for covering an aerial of the mobile phone sending and receiving signals;

the second housing (20) having a sound hole (21) defined at an upper portion thereof to enable sound waves to transmit out therefrom, a key cover (22) formed at a lower portion thereof for accessibility of a keyboard of the mobile phone, and a window (23) defined between the sound hole (21) and the key cover (22) for visibility of a screen of the mobile phone, wherein each of the sound hole (21), the key cover (22) and the window (23) is processed with anti-electromagnetic treatment.

2. The anti-electromagnetic wave box as claimed in claim 1, wherein the first housing (10) and the second housing (20) respectively have a first notch (14) and a second notch (24) defined at respective bottom sides thereof and matching each other to form an opening for accessibility of an adapter of the mobile phone.

3. The anti-electromagnetic wave box as claimed in claim 2, wherein the first notch (14) has a flexible first shield sheet (140) provided thereon, and the second notch (24) has a flexible second shield sheet (240) provided thereon.

4. The anti-electromagnetic wave box as claimed in claim 1, wherein the first housing (10) has a U-like adjustable bracket (12) formed with two upright portions and a lateral portion provided therein, and having a hole (121) defined through the lateral portion.

5. The anti-electromagnetic wave box as claimed in claim 4, wherein the first housing (10) has two first racks (11) formed at two opposite inner walls thereof, and the adjustable bracket (12) has two second racks (120) formed at the upright portions thereof and engaged with the first racks (11) respectively.

6. The anti-electromagnetic wave box as claimed in claim 4, wherein the adjustable bracket (12) has steps formed at corners of the upright portions and the lateral portion thereof.

7. The anti-electromagnetic wave box as claimed in claim 1, wherein the non-shielded area of the first housing (10) is an orifice (15) for the aerial to extend out therefrom.

8. The anti-electromagnetic wave box as claimed in claim 1, wherein the non-shielded area of the first housing (10) has no anti-electromagnetic material plated thereon.

9. The anti-electromagnetic wave box as claimed in claim 1, wherein the first housing (10) has a fastener (101) formed at a second side opposite to the pivoted first side for securing the first and second the housings (10, 20) together.

10. The anti-electromagnetic wave box as claimed in claim 1, wherein the key cover (22) is made of hard material and pivotally mounted on the second housing (20).

11. The anti-electromagnetic wave box as claimed in claim 1, wherein the key cover (22) is made of soft transparent material and integrated with the second housing (20).

12. The anti-electromagnetic wave box as claimed in claim 1, wherein the sound hole (21) has a filter (30) provided therein, which is composed of two casings (31) and a filtering sheet (32) retained between the casings (31).

13. The anti-electromagnetic wave box as claimed in claim 12, wherein the casings (31) each have a plurality of apertures (33) defined therethrough.
