Title (EN) RESONANCE BOX
(FR) BOITE DE RESONANCE
Abstract:
(EN) An apparatus comprising at least one speaker, at least one first compartment for serving as a resonance box for the speaker, at least one second compartment conceived for having a functionality other than to serve as a resonance box, the first compartment and the second compartment being separated by a dividing wall, the dividing wall comprising at least one sound wave passage way for acoustically connecting the first compartment and the second compartment. As a result, the effective space of the resonance box is enlarged by a substantial part of the second compartment, without enlarging the apparatus itself. When using this enlarged effective space for the resonance box, it will have a positive effect on the sound quality. Additionally, a more flexible choice can be made on the speakers used. These positive effects can be achieved without taking up extra space, because of the fact the second compartment also has another functionality than to serve as a resonance box.
(FR) Appareil comportant au moins un haut-parleur, au moins un premier compartiment servant de boîte de résonance pour le haut-parleur, et au moins un deuxième compartiment conçu de manière qu'il ait une fonctionnalité autre que celle d'une boîte de résonance, le premier compartiment et le deuxième compartiment étant séparés l'un de l'autre par une cloison comportant au moins un passage pour ondes sonores assurant la mise en communication acoustique du premier compartiment et du deuxième compartiment. Par conséquent, le volume utile de la boîte de résonance est agrandi par une partie sensible du deuxième compartiment, sans augmentation des dimensions de l'appareil lui-même. L'emploi de cet espace utile plus grand pour la boîte de résonance permet d'obtenir un effet positif sur le plan de la qualité sonore. En outre, le choix des haut-parleurs est élargi. Ces effets positifs peuvent être obtenus sans augmentation de l'encombrement, car le deuxième compartiment présente également une fonctionnalité autre que celle d'une boîte de résonance.
