Abstract
A mobile phone alarm includes a phone device to be attached to a mobile phone and a body device to be carried by a user. The phone device repeatedly transmits a verification signal to the body device. The verification signal has a limited power to be identifiable within a limited, predetermined limited distance, suck as one meter, so that once the distance between the phone device and the body device is greater than the limited pre-determined distance, the body device receives no verification signal and alarms. The phone device also detects the ringing of the mobile phone and once the mobile phone is ringing, the phone device sends a signal to the body device for notifying the user.
