Abstract

L'invention concerne un dispositif acoustique comprenant : un boîtier ; un haut-parleur disposé à l'intérieur du boîtier ; un microphone disposé à l'intérieur du boîtier ; un trou de haut-parleur qui est formé traversant de l'intérieur du boîtier à une première partie de la surface extérieure du boîtier et qui communique avec une unité de sortie du haut-parleur ; un trou de microphone qui est formé traversant de l'intérieur du boîtier à une seconde partie de la surface extérieure du boîtier et qui communique avec une unité d'entrée du microphone ; un couvercle de trou acoustique disposé de façon à recouvrir la première partie et la seconde partie ; une mémoire qui stocke un premier signal de référence indiquant un état normal du couvercle de trou acoustique ; et un processeur disposé à l'intérieur du boîtier et connecté électriquement à la mémoire, au haut-parleur et au microphone. Le processeur est configuré pour : émettre un premier signal à travers le haut-parleur ; recevoir, par l'intermédiaire du microphone, un second signal qui est le premier signal réfléchi par le couvercle de trou acoustique dans une première plage de temps ; comparer et analyser le premier signal de référence et le second signal ; déterminer la cause d'un phénomène anormal sur la base du résultat de la comparaison et de l'analyse du premier signal de référence et du second signal ; et fournir des informations relatives à la cause déterminée. L'invention concerne également divers autres modes de réalisation possibles.
