Abstract
A novel speaker box system for a deep bass amplification consists of a front trumpet horned speaker cover box and a rear speaker box. The rear speaker box consists of a cylindrical box and a speaker installed at one end of the cylinder. The other side of the speaker box has a hole for electrical wires to the speaker. The front trumpet horned speaker cover box consists of a cylindrical box and a trumpet. The trumpet is attached to one end of the cylindrical box. The center of the trumpet has an air port connecting the inner side of the trumpet box and the open air. The trumpet horned speaker cover box and the speaker box of this invention are assembled in one set by, including but not limited to, a male thread screw carved on the outside of the speaker box and a female thread screw inside of the trumpet box. Those boxes are assembled in one set for a hip-hop or a rap, which needs a deep bass sound. For a classical music or opera, the bass amplifying trumpet horned speaker cover box is separated from the speaker box.
