Abstract
Altavoz dinámico en el cual un imán permanente situado en el centro está conectado magnéticamente con lados opuesto de un entrehierro con preferencia anular caracterizado por el hecho de que una pieza polar que forma un lado del entrehierro es apretada elásticamente contra una de las caras polares del imán al paso que una pieza de yugo que forma el otro lado del entre-hierro va sujeto a un yugo o culata que sostiene la otra cara polar del imán.
