Abstract

HAUT-PARLEUR PLAN ISODYNAMIQUE A BOBINAGES CROISÉS Le haut-parleur comprenant une membrane (2) de type plan et un premier ensemble formé d’un bobinage plat (3) supporté sur une première face de ladite membrane (2) et d’au moins un barreau aimanté (6) fixé à un premier support (7) en regard de la première face. Le bobinage est formé de rubans conducteurs (5) parallèles entre eux et le au moins un barreau aimanté est disposé parallèlement aux rubans conducteurs et a une direction Nord/Sud de champ magnétique perpendiculaire aux rubans conducteurs. Conformément à l’invention, le haut-parleur comprend un deuxième ensemble formé d’un autre bobinage plat (4) supporté sur une deuxième face de la membrane et d’au moins un autre barreau aimanté fixé à un autre support en regard de la deuxième face, ce deuxième ensemble ayant une configuration générale analogue au premier ensemble mais étant disposé perpendiculairement à celui-ci. Fig.1ISODYNAMIC PLAN SPEAKER WITH CROSSED COILS The loudspeaker comprising a membrane (2) of planar type and a first assembly formed of a flat winding (3) supported on a first face of said membrane (2) and at least a magnetic bar (6) fixed to a first support (7) facing the first face. The winding is formed of conductive ribbons (5) parallel to each other and the at least one magnetic bar is arranged parallel to the conductive ribbons and has a North/South direction of magnetic field perpendicular to the conductive ribbons. According to the invention, the loudspeaker comprises a second assembly formed of another flat winding (4) supported on a second face of the membrane and at least one other magnetic bar fixed to another support facing the second face, this second assembly having a general configuration similar to the first assembly but being arranged perpendicularly to it.
