  2. Loudspeaker - Wikipedia

    en.wikipedia.org/wiki/Loudspeaker

    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.

  3. Electrostatic loudspeaker - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_loudspeaker

    Manufacturers who only make electrostatic-type speakers include SoundLab, Audiostatic, JansZen and Sanders Sound Systems (previously Innersound). Other manufacturers currently producing electrostatic loudspeakers include Solosound, [6] King's Audio, [7] Panphonics, [8] Cadence Audio, [9] T+A [10] and Silberstatic, [11] Blanko.nu.

  4. Loudspeaker acoustics - Wikipedia

    en.wikipedia.org/wiki/Loudspeaker_acoustics

    Listening to sound in an anechoic "dead" room is quite different from listening in a conventional room, and, while revealing about loudspeaker behaviour it has an unnatural sonic character that some listeners find uncomfortable. Conventional stereo reproduction is more natural if the listening environment has some acoustically reflective surfaces.

  5. Horn loudspeaker - Wikipedia

    en.wikipedia.org/wiki/Horn_loudspeaker

    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.

  6. Electrical characteristics of dynamic loudspeakers - Wikipedia

    en.wikipedia.org/wiki/Electrical_characteristics...

    If a home hi-fi amplifier specifies 8 ohm or greater loads, care should be taken that loudspeakers with a lower impedance are not used, lest the amplifier be required to produce more current than it was designed to handle. Using a 4 ohm loudspeaker system on an amplifier specifying 8 ohms or greater could lead to amplifier failure.

  7. Line array - Wikipedia

    en.wikipedia.org/wiki/Line_array

    A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded ...

  8. Piezoelectric speaker - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_speaker

    A piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a "piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sound. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and ...

  9. Plasma speaker - Wikipedia

    en.wikipedia.org/wiki/Plasma_speaker

    Plasma speaker designs ionize ambient air which contains the gases nitrogen and oxygen. In an intense electrical field these gases can produce reactive by-products, and in closed rooms these can reach a hazardous level. The two predominant gases produced are ozone and nitrogen dioxide.
