Cell phone vibrator motor behavior


Overview. We're often asked how to adjust the vibration amplitude or frequency of our various vibration motors.
In this article we'll look at how simple it is, why it can be useful, and how we can predict the behaviour of a motor using the driving voltage and Typical Performance Characteristics graph. This will be a more.

While these findings are not fundamentally sur- prising (given that any vibrating object should respond to air vibrations), the fidelity to which this is possible has been somewhat to a phone's vibra-motor may now be able to eavesdrop.

How does a vibrating cell phone or pager work?




Description:Next If you have a cell phone or a pager, then you know that having it ring in the middle of a movie or performance is enough to get you killed in some cities. Vibrating devices that quietly replace the ringer are therefore life-saving devices that are an important part of urban survival! There is, however, a device that takes vibration to high-tech extremes. Any parent whose child owns a Tickle-Me-Elmo doll has experienced this technology. Elmo has a vibration system designed to simulate body-shaking laughter that is powerful enough to cause many children to drop the toy.
