Abstract
A power generating mechanism having a movable element is mounted to a wireless communication device. Movement of the movable element generates electricity via the power generating mechanism to allow a user to make a phone call when a battery of the device is discharged. The power generating mechanism can be a mechanical type or a piezoelectric type, and can involve a keypad, a battery cover, an antenna, a crank, or keypad cover. The wireless device can also include an auxiliary power source and a switch to active the auxiliary power source when needed, and a light adapted to illuminate when a call is being received.
