Abstract
The invention discloses an ultrashort horn speaker comprising a horn barrel, a throat cover and a reflecting tube. The horn barrel is in a horn shape, and the bottom of the horn barrel is closed with a bottom plate. The middle of the throat cover is provided with a sound hole. A vibrating system is fixed at the bottom of the throat cover. An inner throat cover tube coaxial with the sound hole is integrated to the upper portion of the throat cover; meanwhile, a middle throat cover tube and an outer throat cover tube are coaxially arranged outside the inner throat cover tube in order. After entering the inner throat cover tube from the sound hole, sound passes six bends and comes out; the heights and diameters of the tubes are configured to meet the fact that when the sound propagates after assembly, the actual sectional area of a sound path increases in a gradual exponential form.
