The multiple entry horn (also known under the trademarks CoEntrant, Unity or Synergy horn) is a manifold speaker design; it uses several different drivers mounted on the horn at stepped distances from the horn's apex, where the high frequency driver is placed. Depending on implementation, this design offers an improvement in transient response ...
The effective non-lethal range of an AHD depends on the total acoustic output of the unit. Typically, this range is 50 metres (160 ft) or less. In addition to its "voice" feature, which acts as a loudspeaker , the LRAD has an "alert" feature, which emits loud chirping or beeping sounds, which can be used at the top of the decibel range of the ...
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.

A Canadian “Super Scooper” aircraft fighting the Palisades Fire in Los Angeles had to be grounded after it hit a drone flying in restricted airspace over the devastating blaze on Thursday, the ...
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 ...
