Abstract

Anti-theft alarm device for car radios, characterized in that it consists of an intelligent system connected with a bitonal oscillator connected to an audio amplifier, whose intelligent system comprises four diodes, two of which incorporate the terminals to which the radio is connected so that during the normal connection of the same, the bitonal oscillator and the audio amplifier are inactive in the passive condition of the alarm device, whereas, if both a button, hidden for the thief, and related a timer, a nand gate causes a change of being on its way out, by tilting a formed scale theft of the radio is attempted without pressing while two other nand gates, whose first resistance gate positively polarizes the base making it conductive, so that this negative voltage bitonal amplifier that produces the alarm sounds that are amplified by the audio amplifier.
