Abstract
Electronic acoustic warning device, characterized by comprising a closed insulating box in which a coil is housed on one of the sides of whose reel is fixed a printed circuit board that is traversed by the fixed core of the coil, inside the whose box is disposed a membrane in which an elastic intermediate tongue is formed that supports a magnet facing the core of the coil and of the same polarity, whose membrane is fixed, with the interposition of a separating frame through which the tongue passes over the tongue. A vibratory membrane joined together the front bottom of the box from which said vibrating membrane is separated by a recess of said bottom, whose magnet support tongue has on its opposite face to which the magnet is attached a percussion projection which, when oscillating the elastic tongue when the coil is excited, hits the vibratory membrane that determines the warning sound which has pass through the open uras provided in the bottom of the box.
