I-woofer yakhiwe nge-electromagnet, i-coil kanye nefilimu ye-horn, eguqula ugesi ube yi-mechanical wave. Isimiso se-physics sithi lapho ugesi udlula kwi-coil, kukhiqizwa insimu ye-electromagnetic, futhi isiqondiso sensimu yamagnetic siwumthetho wesandla sokunene. Ake sithi i-loudspeaker idlala i-C ku-261.6Hz, i-loudspeaker ikhipha i-261.6Hz mechanical wave bese ithumela ukulungiswa kwe-C wavelength. I-speaker ikhiqiza umsindo lapho i-coil, kanye nefilimu ye-speaker, ikhipha i-mechanical wave, edluliselwa emoyeni ozungezile. [1]
Kodwa-ke, ngenxa yokuthi ubude be-wave wave yomshini obuzwiwa yindlebe yomuntu bulinganiselwe, ububanzi be-wavevel buyi-1.7cm -- 17m (20Hz -- 20 00Hz), ngakho-ke uhlelo lwesikhulumi olujwayelekile luzobekwa kulolu hlu. Izikhulumi ze-electromagnetic zakhiwe cishe ngohlelo lwamandla kagesi (kufaka phakathi: ikhoyili yezwi lemagnethi, eyaziwa nangokuthi ikhoyili kagesi). Uhlelo lwe-wave yomshini (kufaka phakathi: ifilimu yomsindo, okungukuthi, igagasi le-diaphragm dust cover), uhlelo lokusekela (kufaka phakathi: uhlaka lwe-basin, njll.). Isebenza ngendlela efanayo naleyo engenhla. Inqubo yokuguqulwa kwamandla isuka emandleni kagesi iye emandleni kazibuthe, bese isuka emandleni kazibuthe iye emandleni wamaza.
Isikhulumi se-bass kanye nesikhulumi se-treble, isikhulumi esiphakathi esinesistimu yomsindo, igagasi elide, ubude be-wavelength obude, senza izindlebe zabantu zikhiqize umuzwa ofudumele, umuzwa oshisayo, futhi zenze abantu bajabule, bajabule, okuvame ukusetshenziswa e-KTV, ebhawa, esiteji nakwezinye izindawo zokuzijabulisa ezibanzi.
