Abstract (en)
[origin: WO0039766A2] The invention relates to an anti-theft element for acoustic magnetic security systems, comprising a module which is positioned in a housing and has at least one magnetic element and a metal platelet. To largely protect said element against manipulation, notably deactivation by strong magnetic fields, without a significant increase in size the invention provides for the magnetic element to be embodied by a magnetic film which is polarized in the direction of the north or south pole.
