Abstract

Mejoras en los transductores electro-acústicos caracterizadas por un transductor electroacústico en el que la armadura, de un material magnéticamente blando, está montada pivotando de modo que accione un diafragma o que sea accionada por éste, en el que la armadura tiene uno de sus extremos, por lo menos, situado entre dos piezas polares, en el que cada una de estas piezas polares está formada por un imán permanente, en el que dicho uno de sus extremos es también un imán permanente, en el que dicho uno de sus extremos es también un imán permanente, en el que los sentidos en que dichos imanes tienen su polaridad es tal que cada polo magnético de la armadura está frente a un polo de la misma polaridad que el mismo, en que dichos imanes son físicamente de menor tamaño que dicha armadura pero de un material que posee una fuerza coercitiva relativamente alta y tal que se ha provisto de una o más bobinas para el circuito magnético a la (las) que se aplican unas corrientes de accionamiento o biende la (las) que se toman unas corrientes debidas a una acción bien determinadas del diafragma.
