Abstract
Improvements in the electro-pneumatic horns characterized by comprising a housing with a recessed bottom and a circular flange that serves as a flange plate inside which are lodged two coils with magnetic core and a supporting bridge provided with two electrical interrupting contacts when synchronized with the vibrations of a membrane provided with a nucleus that is magnetically requested by the cores of the spools whose actions produce the opening and closing of the contacts by cutting and establishing the current that gives rise to the attractions and therefore to the vibrations of the membrane.
