Device for providing built-in invisible speaker for home theater system, has speaker, elliptical reflector, and slot, where sound waves emitted by speaker is reflected by reflector and focused to navigate through slot toward listener

The device has a speaker (2), an elliptical reflector (3), and a slot (5), where sound waves emitted by the speaker is reflected by the elliptical reflector and focused to navigate through the slot toward a listener (4). The speaker is placed on a plane perpendicular to a support of an enclosure (1)...

description The device has a speaker (2), an elliptical reflector (3), and a slot (5), where sound waves emitted by the speaker is reflected by the elliptical reflector and focused to navigate through the slot toward a listener (4). The speaker is placed on a plane perpendicular to a support of an enclosure (1), to radiate the sound waves towards the elliptical reflector, where a scattering angle of the sound waves is varied by varying parameters of the reflector and an inclination of a plane of the speaker. Actuellement, toutes les enceintes audio encastrables sont constituées d'un ou plusieurs haut-parleurs rayonnant de manière directe à travers une grille opacifiante. L'invention concerne un dispositif permettant de faire rayonner des haut-parleurs à travers une fente, sans les rendre visibles. L'onde sonore émise par les haut-parleurs est réfléchie par un réflecteur elliptique qui la focalise pour la diriger à travers la fente, vers l'auditeur. Ce dispositif s'applique à la construction de toute enceinte acoustique, dans laquelle il est nécessaire de cacher les haut-parleurs, sans dégrader la qualité acoustique.
