20110115429 | Wireless Charging Adapter Compatible With Wall Charger And Wireless Charging Plate - Example embodiments are disclosed for wirelessly charging batteries of relatively small devices, such as wireless headsets, using a relatively large wireless charging plate. In example embodiments of the invention, a high permeability magnetic field concentrator has a generally frusto-conical shape with a base at one end, tapering down to a pole at the opposite end. The concentrator is configured to concentrate magnetic flux at a lower flux density incident at the base from a proximate power transmitting coil having a relatively large surface area in a wireless charger. The magnetic flux exits at a higher flux density at the pole end proximate to a power receiving coil having a relatively small surface area in a utilization device. The higher density magnetic flux couples with the power receiving coil, using contact-less electromagnetic induction. The wireless charger may be a charging plate and the utilization device may be a wireless headset. The magnetic field concentrator enables gathering sufficient power by the relatively small power receiving coil to charge the headset's batteries within a reasonable time. | 05-19-2011 |
