(ar) Woofer o altavoz de graves es el término usado comúnmente para designar al altavoz diseñado para producir sonidos de bajas frecuencias, frecuentemente entre los 40 hasta 1000 hercios o más. La palabra surgió de la onomatopeya inglesa del ladrido de un perro, woof (en contraste con el nombre usado para los altavoces de altas frecuencias, tweeter). En pocas palabras, un woofer produce sonidos graves y agudos, pero graves en mayor parte. El altavoz de graves es un dispositivo electromagnético. Utiliza un cono, unido por medio de adhesivos a una bobina de voz rodeada, a su vez, por el campo magnético de un imán permanente. La bobina de voz y el imán en la base forman un motor eléctrico lineal. Cuando la corriente eléctrica fluye por la bobina, esta se mueve respetando la regla de la mano derecha, causando el ascenso o descenso del cono, dando lugar a un movimiento similar al de un pistón. El movimiento creado en el cono produce las ondas sonoras de salida.

(ko) A woofer or bass speaker is a technical term for a loudspeaker driver designed to produce low frequency sounds, typically from 50 Hz up to 1000 Hz. The name is from the onomatopoeic English word for a dog's bark, "woof" (in contrast to the name used for loudspeakers designed to reproduce high-frequency sounds, tweeter). The most common design for a woofer is the electrodynamic driver, which typically uses a stiff paper cone, driven by a voice coil surrounded by a magnetic field. The voice coil is attached by adhesives to the back of the loudspeaker cone. The voice coil and the magnet form a linear electric motor. When current flows through the voice coil, the coil moves in relation to the frame according to Fleming's left hand rule for motors, causing the coil to push or pull on the driver cone in a piston-like way. The resulting motion of the cone creates sound waves, as it moves in and out. At ordinary sound pressure levels (SPL), most humans can hear down to about 20 Hz. Woofers are generally used to cover the lowest octaves of a loudspeaker's frequency range. In two-way loudspeaker systems, the drivers handling the lower frequencies are also obliged to cover a substantial part of the midrange, often as high as 2000 to 5000 Hz; such drivers are commonly termed mid woofers. Since the 1990s, a type of woofer (termed subwoofer), which is designed for very low frequencies only, has come to be commonly used in home theater systems and PA systems to augment the bass response; they usually handle the very lowest two or three octaves (i.e., from as low as 20 to 80 or 120 Hz). (en) Een woofer is een luidspreker die speciaal geschikt is voor de weergave van geluid met lage frequentie, de lage tonen. Afhankelijk van de diameter van de luidspreker en tal van variabele waarden is een woofer in staat de lage tonen weer te geven. Een grote diameter zal resulteren in een groot bewegend oppervlak. De geluidsdruk, met bijvoorbeeld 1 watt of 2,83 volt zal relatief groot zijn. Maar tegelijk zal de massa ook wat groter zijn dan die van een kleinere woofer. Hierdoor kan deze luidspreker doorgaans lagere tonen weergeven, mits de kastconstructie klopt. Woofers zijn er in de standaardmaten: ca. 45, 38, 30, 25, 20 en 17 cm. Worden ze nog kleiner dan zijn het meestal laag-midden-toners. Woofers hebben net als tweeters te maken met bundeling als gevolg van het feit dat afgestraalde tonen op een gegeven moment een kleinere golflengte hebben dan de diameter van de luidspreker. Hierdoor zijn kleinere luidsprekers vaak beter te gebruiken voor de weergave van middentonen tot ca. 3000 hertz. Om deze reden zijn luidsprekers van 17 cm en 13 cm doorgaans niet alleen woofer maar ook middentoner. De woofer verplaatst lucht en werkt het efficiëntst als er geen akoestische kortsluiting ontstaat. Om die reden is de behuizing (de luidsprekerbox of de kastconstructie) bepalend voor de prestatie.

Solitamente viene accompagnato da almeno un tweeter, ottimizzato per riprodurre l'estremo alto, o medio alto, della gamma acustica, in sistemi di altoparlanti a due vie. In sistemi di altoparlanti più complessi, tre o più vie, compare anche il midrange, progettato per riprodurre le frequenze della gamma media. Gli altoparlanti sono di norma montati e cablati in un'unica cassa, detta diffusore acustico.Esistono diverse modalità di accoppiare il woofer al mobile, sia come unità singola o in unione ad altri woofer, solitamente identici tra loro. I sistemi più popolari sono la sospensione pneumatica, il bass reflex, il , il carico asimmetrico, il labirinto acustico e la tromba. (it) Woofer é um alto-falante usado para reproduzir freqüências graves e médias. Possuem borda rígida e seu tamanho pode variar de 1.2" a 21", um woofer com maior área de cone irá produzirr mais SPL e terá melhor resposta nas frequências de grave e sub-grave, já um woofer com menor área ira proporcionar uma melhor resposta em frequências de médio-grave e médios. Woofers para reprodução de graves e médio-graves utilizam uma frequência geralmente entre 40 a 4500 Hz. Existe tantos os que são fabricados especialmente para sonorização profissional quanto aqueles que são para a linha automotiva. O woofer é um dispositivo adequado para ambientes abertos pois gera ondas sonoras de alta intensidade e de longo alcance. * Som automotivo * subwoofer * mid-bass * mid-range * tweeter (pt) |
