This is a small box of 3"x 3"x 2", portable, powered by 5V. It is provided with a 3 watt speaker for emitting high decibel sound.
This is designed particularly with ladies in mind since mostly they are victims for robbery, sexual and physical attacks. When attacked, the victim is dumb founded initially by shock to raise the voice. After recovering from shock, it takes many seconds before which the attacker runs away.
This is provided with a single key. A pre recorded voice of a crying woman's voice with fast blowing police siren is provided. If the victim holding this device is conscious to press the single button at attack or at the approach of an attacker. the high decibel voice will certainly scare away. Components are test selected to ensure infallibility at the emergency occasions.
