Woofer amapangidwa ndi electromagnet, coil ndi nyanga filimu, amene amasintha panopa kukhala mechanical wave.Mfundo ya fizikiya ndi yakuti pamene panopa ikudutsa pa coil, gawo la electromagnetic limapangidwa, ndipo mayendedwe a maginito ndi lamulo lamanja.Tiyerekeze kuti chowulira mawu chimayimba C pa 261.6Hz, chowuzira chokweza mawu chimatulutsa 261.6Hz mechanical wave ndikutumiza kusintha kwa mafunde a C.Wokamba nkhani amatulutsa mawu pamene koyiloyo, pamodzi ndi filimu yolankhulira, imatulutsa mafunde opangidwa ndi makina, omwe amatumizidwa ku mpweya wozungulira.[1]
Komabe, chifukwa utali wa mafunde omwe khutu la munthu ungamve ndi wocheperako, kutalika kwa mafunde ndi 1.7cm -- 17m (20Hz -- 20 00Hz), kotero kuti pulogalamu yoyankhulira zambiri idzakhazikitsidwa mosiyanasiyana.Zolankhulirana zamagetsi amapangidwa pafupifupi ndi mphamvu yamagetsi yamagetsi (kuphatikiza: koyilo ya mawu yamagetsi, yomwe imadziwikanso kuti coil yamagetsi).Makina opangira mafunde (kuphatikiza: filimu yomveka, ndiye kuti, nyanga ya diaphragm fumbi lophimba), njira yothandizira (kuphatikiza: chimango cha beseni, ndi zina).Zimagwira ntchito mofanana ndi pamwambapa.Njira yosinthira mphamvu imachokera ku mphamvu yamagetsi kupita ku mphamvu ya maginito, kenako kuchokera ku mphamvu ya maginito kupita ku mphamvu yoweyula.
Bass speaker ndi treble speaker, speaker medium with sound system, wave wave, wavelength wautali, zimapangitsa makutu a anthu kukhala ofunda, kumva kutentha, kupangitsa anthu kusangalala, kusangalala, kugwiritsidwa ntchito nthawi zambiri mu KTV, bar, siteji ndi malo ena osangalatsa. .
