Improved electric buzzer, of the type constituted by an electromagnetic coil acting on a mobile armature determined by a vibrating foil, characterized essentially by the fact that in the region of said flexible foil located opposite the core of the coil there is a metallic mass, preferably in the form of a plate of appropriate dimensions, which, in addition to acting as an inert medium for a good oscillation of the sheet in its action and reaction phases, ensures the conduction of the magnetic flux, determining the aforementioned mass, which is what it comes into intermittent contact with the core, high intensity vibrations that result in a perfectly audible sound.
