Abstract

A communication device, and battery there for, are provided. In at least one of the battery and the communication device is provided a magnetic shield portion for routing magnetic flux away from the receiver when the radio is in operation. The magnetic shield portion can be incorporated into at least one of the battery and the communication device. When the battery is inserted into mobile communication device, the magnetic shield portion is located substantially between a battery portion, in the battery, and the receiver.

Claims (13)

1. A battery comprising:

a case;

a battery portion enabled to provide electrical power to a device; and

a planar magnetic shield portion internal to the case, the planar magnetic shield portion enabled to provide structural support to the battery and route magnetic flux from the battery portion away from a receiver of the device when the battery is inserted therein.

2. The battery of claim 1 , wherein the planar magnetic shield portion is substantially parallel to a side of the battery portion.

3. The battery of claim 1 , wherein the planar magnetic portion is on a side of the battery portion enabled to be oriented towards the receiver of the device when the battery is inserted therein.

4. The battery of claim 1 , wherein the planar magnetic shield portion is enabled to be located substantially between the battery portion and the receiver of the device when the battery is inserted therein.

5. The battery of claim 1 , wherein the planar magnetic shield portion comprises a box substantially encompassing the battery portion.

6. The battery of claim 5 , wherein the box comprises apertures for contacting the battery portion.

7. The battery of claim 1 , further comprising a planar structural element, internal to the case that provides further structural support to the battery.

8. The battery of claim 7 , wherein the planar magnetic shield portion and the planar structural element substantially sandwich the battery portion.

9. The battery of claim 7 , wherein the planar structural element is enabled to route the magnetic flux there through, such that the magnetic flux is routed through the planar magnetic shield portion and the planar structural element.

10. The battery of claim 1 , wherein at least one normal of the planar magnetic shield portion is oriented in a direction of the magnetic flux.
