Abstract

Perfeccionamientos introducidos en las bocinas de doble tono simultáneo que funcionan por aspiración caracterizados por el hecho de que el tono del sonido emitido por el conjunto del avisador acústico puede graduarse modificando la constante presión de un tope que actúa contra la parte central del disco metálico que constituye la membrana vibratoria el cual limita la amplitud de sus vibraciones por la acción expansiva de un muelle espiral cuya tensión puede graduarse desde el exterior de la caja que contiene el vibrador mediante un tornillo de ajuste.Improvements introduced in the simultaneous double tone horns that work by aspiration characterized by the fact that the tone of the sound emitted by the acoustic warning unit can be graduated by modifying the constant pressure of a stop that acts against the central part of the metal disk that constitutes the vibrating membrane which limits the amplitude of its vibrations by the expansive action of a spiral spring whose tension can be adjusted from the outside of the box containing the vibrator by means of an adjustment screw.
