A horn loudspeaker is a loudspeaker or loudspeaker element which uses an acoustic horn to increase the overall efficiency of the driving element(s). A common form (right) consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air.
The researchers invented the exponential horn, and, on realizing that it needed to be nine feet long to reproduce the lowest frequencies on the new discs, designed a method for "folding" the horn into a cabinet of practical size. The design was released by Victor as the "Orthophonic" Victrola in the autumn of 1925.
A patent horn loudspeaker. Loudspeakers are often built into horn-shaped enclosures or use horns. Most often the higher-frequency elements (tweeters and midranges) use horns, sometimes with acoustic diffraction lenses to spread the sound waves in a horizontal pattern at ear-level and limit the vertical pattern. An audio driver (e.g., a speaker ...
In fact, this sound machine offers only the essentials, including a volume knob, a timer, and just six built-in sounds (White Noise, Thunder, Ocean, Rain, Summer Night, and Brook).
