A speaker that is used for high frequencies. It can handle relatively high power and has a very specific spread or dispersion to the sound.

A megaphone shaped piece used in some speakers to provide a small driver with a larger radiating surface.

a warning device operated by the engineer. The horn replaced the traditional whistle.

a speaker design using its own funnel shaped conduit to amplify, disperse, or modify the sounds generated by the internal diaphragm of the speaker.

a noise made by the driver of an automobile to give warning;

an alarm device that makes a loud warning sound

a device on an automobile for making a warning noise

an emergency warning device, never use it except in an emergency

a safety warning

A type of enclosure where the driver is coupled to the air via a tube whose area increases along its length. See basshorn.

An expanding acoustical waveguide in front of a loudspeaker driver, or compression driver, that shapes the wavefront of the sound as it radiates away from the source. This allows designers to control vertical and horizontal dispersion characteristics, essential to achieving good audience coverage in sound reinforcement systems, and increasingly used to finesse the frequency-dependent directivity of consumer loudspeakers to improve sound quality. Being acoustical transformers, horns can also improve the acoustical efficiency of the drivers. See: Compression Driver, Driver, Directivity, Throat.

An acoustical transformer which, when coupled to a driver, provides directivity and increases the driver's loudness. See: Compression Driver

1) The part of the speaker that emits midrange and higher range frequencies. 2) A speaker or speaker enclosure where sound waves are put into a narrow opening (by a speaker cone or driver) and the narrow opening flairs out to a larger opening.

A type of speaker that looks like a horn. These speakers have small drivers and very large mouths; the horn shape serves to transform the small radiating area of the driver into the much larger radiating area of the mouth of the horn.

A flared structure often used to assist a loudspeaker. Horn-loaded loudspeakers are considerably more efficient than ordinary moving coil loudspeakers in turning electrical into acoustic energy.

A type of speaker that often looks like a horn. These speakers have very small drivers and very large mouths; the horn shape serves to gradually match the high impedance of the driver to the low impedance of the air.

Element used in some speaker designs to increase efficiency by placing the driver at the end of a megaphone-like piece if metal, plastic, wood or other material that expands outward from the driver similar to an ice cream cone expanding outward from its point (apex).

an acoustical tool that transfers mechanical vibrations from the transducer and booster to the parts to be assembled.

A horn is a tapered, sound guide designed to provide an acoustic impedance match between a sound source and free air. This has the effect of maximising the efficiency with which sound waves from the particular source are transferred to the air. Conversely, a horn can be used at the receiving end to optimise the transfer of sound from the air to a receiver.
