It is well known that lots of mobile accessories have a special shiny effect and hang mobile accessories with the cell phone to some extent can enhance the display service so that you can find the caller in a short time when you stay in a noisy place.
The basic principle of cell phone widgets is like that. You may know that inside the cell phone widget is a coil and in the middle is a metal wire. Both of them do not contact with each other in normal times but they just like a switch controlled by electromagnetic waves. As soon as the cell phone receives electromagnetic waves will generate magnetic field thus make the coil and the metal wire have a short contact. The device just like the switch contacts and if the little lamp gives out light or some mobile accessories emit sound will make the electromagnetic radiation work in the end.
Some cell phones could not produce this effect because the intensity of the electromagnetic radiation of coil and the metal wire always could not reach the special value but the moment when some cell phones transmit and receive will produce sufficient electromagnetic waves to make switch close or open thus produce the effect of induction. However, due to the effects of flash and emit sound of the cell phone widgets are supplied power by portable battery so it could not work when the battery has no electricity.
