PURPOSE: A speaker with enhanced output efficiency is provided to prevent the reduction of a speaker output by inserting a duct and a front panel into a baffle. CONSTITUTION: The structure of an enclosure is the shape of a cube. The enclosure includes an opened single-side. A speaker unit is arranged in the single-side of the enclosure. The speaker unit changes an electric signal to a sound wave. A flat type baffle(140) is fixed to the opened single-side of the enclosure. A tube shape duct is inserted into a first connection unit formed in a side of the baffle. The tube shape duct is expanded to the inside of the enclosure. A front panel(130) covers the baffle. The front panel is installed in the opened single-side of the enclosure. One terminal of the duct is inserted into a groove formed in the first connection unit. |
