A communication method for wireless power charging system having a device comprising a speaker that is configured to play audio-coded data-file, the method comprising:
- detecting, by a controller of a transmitter, voltage or current fluctuations in a coil of the transmitter;
- executing an audio-coded data-file reception-sequence;
- determining if the device comprising a power receiver;
- and
- activating wireless power transmission to the device,
- wherein the fluctuations correspond to audio-tones composing the audio-coded data-file played by the speaker, and wherein the reception-sequence decode and
- process the audio-tones for assembling the data-file.
A transmitter of a wireless power charging system having a device comprising a speaker configured to play audio-coded data-file, the system comprising:
- a transmitter, having a controller, wherein the controller is configured to detect voltage or current fluctuations in a coil of the transmitter resulting from external magnetic fields caused by the speaker playing the audio-coded data-file, wherein the fluctuations correspond to a plurality of different audio-tones that the audio-coded data-file is composed of, and wherein the controller is also configured decode and process the audio-tones for assembling the data-file and store the file in a memory of the controller.
