Wireless charger for electronic device
First Claim
1. A wireless charger for an electronic device, comprising:
- one or more charge chambers, the one or more charge chambers including an opening receiving an electronic device and transmitting coils disposed adjacent to the opening; and
an electric power supply circuit supplying power to the transmitting coils,wherein the transmitting coils at least partially enclose a circumference of the opening and are configured such that;
outside of the charge chambers, a magnetic field generated by one of the transmitting coils is subtracted or canceled by another magnetic field generated by another of the transmitting coils, andinside the charge chambers, the magnetic fields generated by the one and the another of the transmitting coils are concentrated in the opening which the electronic device for reception of energy is located,wherein the transmitting coils have a structure of charging and/or providing electrical power to each respective electronic device randomly and three-dimensionally oriented in each of the charge chambers, by generating the magnetic field, andwherein distribution of the magnetic field is determined by secondary induced currents on metal surfaces of the electronic device according to a position and the three-dimensional orientation of the electronic device inside each of the charge chambers.

Abstract
A wireless charger for an electronic device is provided, which includes one or more charge cells formed by one or more structures of transmitting inductance coils, each of the charge cells receiving an electronic device, and an electric power supply circuit of transmitting coils. The transmitting coils surround the charge cells on at least two sides, respectively, and generate a uniformly distributed magnetic field such that the magnetic fields, generated by currents in parts of the structure of the transmitting coils, are mutually subtracted out of the charge cells and summarized inside the charge cell in an area in which the electronic device for reception of energy is located.
