The technology entails winding an audio cable around a charging mechanism to form an inductive receiving coil, then picked up by a magnetic field to charge the device.
Usually this would mean a larger coil would be required, meaning the size of the iPhone or iPods would also increase, going against Apple's creed of smaller, thinner, lighter.
But the three clever whizzes that developed this new concept found a way around that.
Here's a summary of the technology as outlined in the patent application: "This technique involves winding an audio cable for the electronic device around a charging mechanism multiple times so that one or more conductors in the audio cable form an inductive receiving coil.
"Next, a magnetic field is created through the charging mechanism to induce a current in the inductive receiving coil. Finally, the induced current in the inductive receiving coil is used to charge a rechargeable battery for the electronic device."
