Samsung's invention provides for a wireless charging device in which a sheet is provided at a predetermined separation distance between top of a housing and a shield-can. The sheet may shield a transmission resonator from the electromagnetic field emanating from the system board in the shield-can, and/or vice versa. Various embodiments of the present disclosure may also provide for a transmission resonator that simultaneously generates a vertical magnetic field and a horizontal magnetic field so that an electronic device can be charged via a side surface of the wireless charging device as well as on an upper surface. Accordingly, the product can be miniaturized as a large pad is not necessary and charging efficiency of the product can be enhanced as well.
The charger will be able to charge a camera, wearable device, necklace, electronic glasses, head-mounted-device, smartwatch, electronic tattoos smartphones and tablets.
