Improvements in the equipment for acoustic signals, particularly intended for vehicles, essentially characterized by the fact of ordering the displacement of air to a pump-type pneumatic mechanism in which a pressure element that compresses an air chamber is included, to which camera is connected conveniently the sound body and which is endowed with elastic organs that return the pressure element to the starting point when the external action ceases on it.
