Works, reasoning...

This does work, but some devices more than others. For example, there is a fan inside everyone of the iOS devices. When it uses enough RAM or plays a high pitched sound, it blows to keep the device cool. Higher powered fans are included in devices that need more cooling due to their RAM capacity. This plays a high pitched sound, making the fan spin at its highest level, which finds its way through the speakers.
