Abstract
Improvements introduced in the construction of electric horns for vehicles, characterized in that the acoustic effect, carried out by the excitation alternations of an electromagnet on a mobile reinforcement fixed to a metal membrane, is regulated by means of the variation of the pressure exerted by the the fixed contact on the movable contact of a switch that, activated by the mobile armature itself, gives rise to interruptions of the electric current, previously rectified in complete and filtered wave, causing the excitation alternations of the electromagnet.
