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]
The nominal impedance rating of consumer loudspeakers systems can aid in choosing the correct loudspeaker for a given amplifier (or vice versa). 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 ...
Exploded-view diagram showing the IMF Reference Standard Professional Monitor Mk IV speaker by renowned transmission line loudspeaker pioneer John Wright (of IMF/TDL), from the 1970s. The complex shape of the transmission line allowed a full frequency range of 17 Hz to "beyond audibility" and loudspeaker sensitivity of 80 dB (specified as 96 dB ...
Loudspeaker acoustics is a subfield of acoustical engineering concerned with the design of loudspeakers. [1] It focuses on the reproduction of sound and the ...
Speaker drivers are the primary means for sound reproduction. They are used among other places in audio applications such as loudspeakers, headphones, telephones, megaphones, instrument amplifiers, television and monitor speakers, public address systems, portable radios, toys, and in many electronics devices that are designed to emit sound.
Gilbert Briggs, founder of Wharfedale Loudspeakers in the UK, undertook several studies of aging effects in speaker drivers in the 1950s and 1960s, publishing some of the data in his books, notably Loudspeakers: The Why and How of Good Reproduction. [25] There are also mechanical changes which occur in the moving components during use.
Schematic showing an electrostatic speaker's construction and its connections. The thickness of the diaphragm and grids has been exaggerated for the purpose of illustration. An electrostatic loudspeaker (ESL) is a loudspeaker design in which sound is generated by the force exerted on a membrane suspended in an electrostatic field.
[1] [2] Acoustically, TL speakers roll off more slowly (less steeply) at low frequencies, and they are thought to provide better driver control than standard vented-box cabinet designs, [3] are less sensitive to positioning, and tend to create a very spacious soundstage. Modern TL speakers were described in a 2000 review as "match[ing] reflex ...
