Abstract

Electro-acoustic warning device of the type that has a box, a vibratory membrane fixed with its peripheral edge to said box in correspondence of an exit opening of the sound, characterized in that said membrane was linked to the moving part of a magnetodynamic assembly which comprises a permanent magnet, intended to provide a magnetic field whose flow lines have a radial movement with respect to a cylindrical coil, movable relatively to the cited permanent magnet, the cylindrical coil being connected in series to a pair of normally closed contacts, which one is fixed and the other mobile; a rod rigidly fixed to the movable part of said dynamic magnetic assembly acting on an elastic support arm of the movable contact to open the pair of contacts mentioned, during the displacement in one direction of the vibrating membrane, to interrupt the supply to the coil thus causing the vibration of the membrane itself.
