How do cell phones vibrate?
To explain how the vibrations happen, How Stuff Works performed an autopsy on one ill-fated Tickle Me Elmo. The doll uses a shaking technology that's exactly the same as a cell phone's, though considerably larger. (Those queasy about Muppet innards should stop reading here.)
Here's what they found: A flywheel motor with a weight is attached to one side. When the motor turns, the weight throws it off balance and creates a wobble. That wobble causes the whole device, be it a friendly plush monster or a sleek cell phone, to jiggle.
Now, ask yourself something: Have you ever tried to answer your phone when it vibrates, only to find it's not actually moving (or even on)? If so, you may have had close encounters with a new phenomenon -- the phantom cell phone vibration. Perhaps you're hoping for a call just a little too fervently. Perhaps your muscles are twitching. To be honest, we're not sure. But to be on the
safe side, maybe it's time you call an exorcist (on a landline, of course).
