Abstract

Altavoz dinámico para alarmas perfeccionado, esencialmente caracterizado por estar constituido mediante la combinación funcional de dos membranas, una tronco-cónica, abierta y solidarizada por el borde correspondiente a su embocadura mayor a una carcasa soporte, concretamente a un escalonamiento determinante en la misma de una embocadura, siendo la otra membrana de cúpula y estando dispuesta entre la carcasa y el conjunto motor, con la particularidad de que la citada membrana de cúpula emerge a través de la abertura central de la carcasa y entronca con la membrana tronco-cónica, que resulta asi esclava de la membrana de cúpula, a la que se solidariza a través del borde de su embocadura menor, quedando consecuentemente la citada cúpula parcialmente alojada en el interior tronco cónico de la membrana externa.
