All speaker drivers have a means of electrically inducing back-and-forth motion. Typically there is a tightly wound coil of insulated wire (known as a voice coil) attached to the neck of the driver's cone. In a ribbon speaker, the voice coil may be printed or bonded onto a sheet of very thin paper, aluminum, fiberglass or plastic.
So much so, that differences in practice between a 16-ohm nominal impedance driver and a 4-ohm nominal impedance driver have not been important enough to adjust for. The amplifier damping factor , which is the ratio of the nominal load impedance (driver voice coil) to amplifier output impedance, is adequate in either case for well-designed ...
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
For example, a typical electrodynamic speaker driver can have a moving mass of tens or hundreds of grams, whereas an electrostatic membrane only has a mass of a few milligrams, several times less than the very lightest of electrodynamic tweeters. The concomitant air load, often insignificant in dynamic speakers, is usually tens of grams because ...
A tweeter or treble speaker is a special type of loudspeaker ... Nearly all tweeters are electrodynamic drivers using a voice coil suspended within a fixed magnetic ...
While suited very well for high frequencies, the AMT can reproduce sound down to 650 Hz. Consequently, the most common use for the AMT driver in consumer electronics today is as a midrange-tweeter or tweeter in high-end multi-driver speakers, sometimes paired with horns, or in the case of Precide's speaker products, with an upward-firing woofer driver.

NOEMA manufactures electrodynamic speaker drivers, loudspeakers, amplifiers, etc. Also the enterprise is engaged in the installation of its products. For example, the company equipped secondary schools, the fountains near Globus Theater, Park named after Kirov, Spartak and Sibselmash stadiums with acoustic systems.
