Abstract
A low frequency horn apparatus including a throat (20), barrel (30) and mouth (40). The barrel (30) includes a series of chambers (50 and 60) wherein the cross-sectional area of each chamber in the series increases linearly from one end of the chamber to the other. The rate of linear increase is greatest in the first chamber 50 in the series. The chambers are in communication with one another so that sound waves entering the throat aperture (20) of the first chamber (50) in the series travel though each chamber in the series and exit the series of chambers through the mouth (40) of the last chamber (60) in the series. Sounds waves may be created by an electroacoustic transducer (70) that includes a cone. Further, the cross-sectional area of the mouth (40) may be less than the cross-sectional area of the cone (78).
