Horn speakers play an important role in transmitting an audio signal. They are used for signaling in order to enhance voice alerts. They are needed for scoring information in open spaces, such as streets, stadiums, squares, as well as industrial premises where noise levels are high.
Fields of application
Previously, horns were used mainly in the film industry and made it possible to reproduce both medium and high frequencies up to 20 thousand hertz. Today, horns no longer play this role, but are used in professional audio equipment. They are part of sophisticated equipment designed for use at home.
The areas in which the equipment is used can be different, as well as the goals. In areas where explosive mixtures are contained, dustiness is increased, gas contamination is observed, loudspeakers can work normally. Such sirens are used in warning systems for warning of danger or emergency: natural disasters, industrial accidents at industrial facilities for various purposes.
Mouthpieces are also used in mines, mines, quarries, they are equipped with marine transport, they are included in the package of ship equipment. With their help, it is easy to transmit messages to all rooms of the vessel, especially to those where the noise level is increased, information is also transmitted to open decks in the same way.
Hand-held megaphones help for advertising purposes, allowing thousands and hundreds of people to hear the information they need. They are needed for sports trainers, those who organize mass events, guides. Employees of the Ministry of Emergency Situations, law enforcement agencies will not do without them.
Kinds
There are all-weather series, they have moisture-proof high power amplifiers. The built-in siren module contains tones in the memory that can be selected using combinations.
Sirens can be activated using the power supply at + 12V, + 24B or + 36B. Power supply is required, but if this is not possible, then you can get it through a pulsed source. Horn converts electrical energy into acoustic.
All of them are light and compact in installation, simple and reliable in operation. They are effective in conditions of increased noise, as well as in harsh climate conditions.
