Abstract

Enceinte accoustique comportant une connexion électrique facilement démontable entre une bobine excitatrice et un circuit imprimé Enceinte acoustique (10) comprenant un circuit imprimé (12), et un haut-parleur (14) comportant une bobine excitatrice, le haut-parleur comprenant deux circuits électriques (36, 38) reliant électriquement la bobine au circuit imprimé et comprenant respectivement deux tresses (40, 42) ayant une première extrémité soudée sur la bobine. Le circuit imprimé définit au moins deux interstices (16, 18), chacun des deux interstices traversant le circuit imprimé et s’étendant dans une direction d’extension (Z) parallèle au circuit imprimé, chacun des deux interstices étant délimité par deux surfaces (20, 22) en vis-à-vis, dont au moins l’une est électriquement conductrice. Chacun des deux circuits électriques comprend une extrémité dans une position insérée, dans laquelle l’extrémité traverse respectivement l’un des deux interstices et est coincée entre les deux surfaces, l’extrémité étant adaptée pour être mobile par rapport au circuit imprimé entre une position éloignée, dans laquelle l’extrémité est à l’écart du circuit-imprimé, et la position insérée. Figure pour l'abrégé : Figure 1Acoustic enclosure comprising an easily removable electrical connection between an exciting coil and a printed circuit Acoustic enclosure (10) comprising a printed circuit (12), and a loudspeaker (14) comprising an exciting coil, the loudspeaker comprising two electrical circuits (36, 38) electrically connecting the coil to the printed circuit and respectively comprising two braids (40, 42) having a first end soldered to the coil. The printed circuit defines at least two gaps (16, 18), each of the two gaps crossing the printed circuit and extending in a direction of extension (Z) parallel to the printed circuit, each of the two gaps being delimited by two surfaces ( 20, 22) facing each other, at least one of which is electrically conductive. Each of the two electrical circuits comprises an end in an inserted position, in which the end respectively passes through one of the two gaps and is trapped between the two surfaces, the end being adapted to be movable relative to the printed circuit between a position remote, in which the end is away from the printed circuit, and the inserted position.
