Narrow Mouth Horn Loudspeaker |
摘要 |
An acoustic horn. In one implementation, the horn includes at least four wall sections, defining a passageway. The cross-sectional area of the mouth is at least ten times the cross sectional area of the throat. The wall sections are dimensioned so that at least one wall section has a dimension at the throat at least ten times a dimension at the throat of a second wall section. In another implementation the cross-section at the mouth is elongated and is be bounded by a continuous curve defining a geometric figure having a major axis at least ten times a minor axis. |
