Abstract
Anti-theft alarm device, characterized in that it consists of a circular box with a slightly flattened spherical bottom and a domed lid, inside which is the anti-theft device, formed by a vibrating membrane buzzer, operated by an electromagnet powered by an electric battery, whose circuit is connected and disconnected by means of a mercury switch, that being the box in stable position remains open, but when said box receives the thrust of the door, behind which it is placed to prevent theft, it easily loses its stability by rolling on the ground or by occupying an inclined position that determines the closing of the mercury switch, which triggers the buzzer, which produces the acoustic alarm signal, which is increased by the resonance made by the box itself of the anti-theft device, whose cover has multiple perforations to facilitate the emission of the alarm sound.
