Abstract

L'invention concerne une enceinte acoustique comprenant un boîtier, une ouverture de sortie sonore utilisée pour une sortie sonore, un couvercle de haut-parleur pour fermer l'ouverture et fixé à une extrémité du boîtier, et un élément de butée agencé à l'extrémité arrière du couvercle de haut-parleur pour que le couvercle de haut-parleur s'appuie contre celui-ci. L'enceinte acoustique comprend également un élément de limitation utilisé pour limiter le couvercle de haut-parleur, jouant ainsi un effet de limitation pour le couvercle de haut-parleur. En raison du fait que le couvercle de haut-parleur s'appuie contre l'élément de butée et ne tombe pas vers l'arrière, l'élément de limitation est apte à jouer un rôle pour empêcher le couvercle de haut-parleur de tomber vers l'avant et fermer ainsi l'ouverture de sortie sonore.
