Abstract

A duct structure of a speaker system which enables a tuning of sound outputted from the speaker system by installing a duct moving means which can move the duct installed in an enclosure. The speaker system comprises an enclosure, at least one speaker unit, and a dividing network which divides a frequency bandwidth. A first duct(16) is installed on one side of the enclosure(10) and is communicated with the outside of the enclosure(10). A second duct(18) is inserted into the first duct(16), and a duct moving means(20) moves the second duct(18)
