Intel has showed off its wireless power transmission technology before with lightbulbs and netbooks, and here it shows it running a speaker playing music. The rear coil broadcasts power electromagnetically, and the smaller front coil, with the speaker in its centre, is tuned to pick up the same frequency.
Intel hopes the technology will be useful for charging devices without wires and possibly within devices such as a laptop, which today carries power from a battery to its screen through a flexible but fallible cable.
