Abstract:
The disclosed embodiments relate to a technique for inductively charging an electronic device. 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.
