Patent

CA 2266361

A loudspeaker, for example, for an in-vehicle hands-free communication system or an in-vehicle entertainment system is provided as part of a vehicle sun visor (10), or as an attachment (24) to a vehicle sun visor so that the loudspeaker can be placed relatively close to the driver's ears and in front of the driver. Accordingly, there will not be any significant tendency for the driver to turn their head when listening to the loudspeaker. The loudspeaker comprises a flat panel (26) which is driven by a piezoelectric actuator (28), enabling an extremely thin construction to be realised and the loudspeaker to be conveniently integrated into the sun visor, or provided as an unobtrusive attachment for the sun visor.

Un haut-parleur, par exemple pour un système de communication "mains libres" ou pour un système récréatif, dans un véhicule, fait partie du pare-soleil (10) ou constitue un élément (24) fixé au pare-soleil, de sorte que le haut-parleur se trouve relativement près des oreilles du conducteur et devant celui-ci. Dans ces conditions, le conducteur ne sera pas enclin à tourner la tête pour écouter le haut-parleur. Le haut-parleur peut comprendre un panneau plat (26) commandé par un dispositif d'actionnement piézo-électrique (28) et réalisé très mince, pour permettre une intégration aisée au pare-soleil. Il peut aussi constituer un élément fixé au pare-soleil d'une manière très discrète.
