Abstract

This item is a speaker box in which two types of back-loaded horns are configured in the center and upper part of a U-shaped pipe, with a structure resembling a human nose and mouth, where the upper central horn faces straight forward and the topmost horn hangs down above the central horn, and the pipe has five types of bass reflex filters to create a structure where resonant sounds collide, and two speaker units can be attached to both ends of the U-shaped pipe.
