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 vuvuzela / v uː v uː ˈ z ɛ l ə / is a horn, with an inexpensive injection-moulded plastic shell about 65 centimetres (2 ft) long, which produces a loud monotone note, typically around B♭ 3 [2] (the first B♭ below middle C). [3] Some models are made in two parts to facilitate storage, and this design also allows pitch variation.
(right) Electric megaphones use a type of horn loudspeaker called a reflex or reentrant horn. The sound waves travel in a zigzag path through concentric widening ducts (b, c, and d) . An electric megaphone is a handheld public address system , an electronic device that amplifies the human voice like an acoustic megaphone, using electric power.
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 ...
The larger the horn, the lower the frequencies at which it can work, since large horns provide coupling to the air at lower frequencies. There are different types of horns, including radial and constant directivity (CD). Horn tweeters may have a somewhat 'different' sonic signature than simple dome tweeters.
Fog Horn was selected to produce the State Fair of Texas rodeo in Dallas, but it was a different event that changed his future. The loudspeaker system was invented.
If you've been shopping in a big box retail store you've probably heard an announcement on the loudspeaker such as, "code yellow toys, code yellow toys." This "code" is one of many innocuous ...
The term loudspeaker may refer to individual transducers (also known as drivers) or to complete speaker systems consisting of an enclosure and one or more drivers.. To adequately and accurately reproduce a wide range of frequencies with even coverage, most loudspeaker systems employ more than one driver, particularly for higher sound pressure level (SPL) or maximum accuracy.
