Abstract
Altavoz perfeccionado, caracterizado porque la embocadura de la armadura en la obtención de ésta queda sin mecanizar y recibe por recalcado la pestaña extrema de un anillo de campo incorporado que constituye el polo magnético externo y conforma al menos parte del bastidor cónico del altavoz.
Permanente magneet uit zeco5, die tenminste met een ijzeren lichaam is verbonden, en werkwijze voor de vervaardiging van een dergelijke per- manente magneet.
Werkwijze voor de vervaardiging van een anisotrope permanente magneet uit poedervormig magneetmateriaal en magneet verkregen onder toepassing van de werkwijze.
