Abstract

L'invention concerne un haut-parleur sous forme d'un panneau résonnant caractérisé par des moyens de suspension placés dans au moins une région du panneau à vitesse moyenne lente. L'invention concerne également un procédé de fabrication d'un dispositif acoustique du type panneau résonnant, consistant à placer au moins une région du panneau à vitesse moyenne lente et à positionner des moyens de suspension dans cette (ces) région(s). Le procédé peut également consister à délimiter une zone active sur le plan acoustique d'un panneau plus grand, par exemple un panneau de garniture décoratif d'un véhicule à moteur, par l'exécution de rainures ou de fentes dans ce panneau, dans des régions de celui-ci à vitesse moyenne lente.
