倒相式扬声器箱是由封闭箱和共振管道所组成的扬声器系统。它与封闭箱系统相比较,其主要优点是:它可利用箱体和管道的共振来扩展重放下限频率,在扬声器和箱体条件符合理想设计条件下,可扩展至扬声器谐振频率
Inverted speaker box is composed of a closed box and the resonance of the speaker system. Its main advantages over closed box systems are that it can extend the lower limit of reproduction frequency by utilizing the resonance of the box and the duct and can be extended to the speaker resonance frequency when the speaker and box conditions meet the ideal design conditions
