Abstract

Una caja acústica con un filtro acústico pasobanda integrado, cerrada por todos lados, con al menos un altavoz y al menos una abertura entre el espacio interior y el exterior de la caja, caracterizada porque dentro de la caja (1) existe una pared divisoria (2) que subdivide el espacio interior en dos espacios parciales (V1, V2) porque está montado un altavoz en un corte existente en la pared divisoria, y porque las frecuencias, resonantes de los sistemas de resonancia formados por los dos espacios parciales, son diferentes.
