I-woofer yakhiwe ngozibuthe kagesi, ikhoyili kanye nefilimu yophondo, eguqula amandla amanje abe amaza omshini. Umgomo we-physics ukuthi lapho i-current idlula ikhoyili, inkambu ye-electromagnetic iyakhiqizwa, futhi isiqondiso senkundla kazibuthe umthetho wesandla sokudla. Ake sithi isipikha sidlala u-C ku-261.6Hz, isipikha sikhipha igagasi lomshini elingu-261.6Hz futhi sithumele ukulungiswa kwe-wavelength engu-C. Isipika sikhipha umsindo lapho ikhoyili, kanye nefilimu yesipika, ikhipha igagasi eliwumshini, elidluliselwa emoyeni ozungezile. [1]
Kodwa-ke, ngenxa yokuthi ubude begagasi begagasi obulungiswayo obuzwiwa yindlebe yomuntu bunomkhawulo, ububanzi begagasi buyi-1.7cm -- 17m (20Hz -- 20 00Hz), ngakho uhlelo lwesipikha esijwayelekile luzosethwa kulobu bubanzi. Izipikha zika-electromagnetic zakhiwa cishe isistimu yamandla kagesi (okuhlanganisa: ikhoyili yezwi likakazibuthe, eyaziwa nangokuthi ikhoyili kagesi). Isistimu yamaza omshini (okuhlanganisa: ifilimu yomsindo, okungukuthi, igagasi lesembozo sothuli lwe-diaphragm), uhlelo lokusekela (okuhlanganisa: uhlaka lwesitsha, njll.). Isebenza ngendlela efanayo nangenhla. Inqubo yokuguqulwa kwamandla isuka emandleni kagesi iye emandleni kazibuthe, bese isuka emandleni kazibuthe iye emandleni amaza.
Isipikha se-bass nesipikha esinyakazayo, isipikha esimaphakathi esinesistimu yomsindo, igagasi elide, ubude begagasi ende, zenza izindlebe zabantu zikhiqize umuzwa ofudumele, umuzwa oshisayo, futhi zenze abantu bajabule, bajabule, evame ukusetshenziswa ku-KTV, ibha, isiteji nezinye izindawo zokuzijabulisa ezibanzi. .
