ABSTRACT:
A sound radiated from the back of a speaker unit passes through a three-dimensional spiral sound passage formed by a coaxial dual-tube structure of an outer tube and an inner tube, and by a spiral partition plate provided to bridge a gap between the outer tube and the inner tube before exiting the speaker system. The cross-sectional area of the spiral sound passage may continuously expand or remain constant.
