I-woofer yenziwe nge-electromagnet, i-coil kunye nefilimu ye-horn, eguqula umbane ube yi-mechanical wave. Umgaqo wefiziksi kukuba xa umbane udlula kwi-coil, intsimi ye-electromagnetic iveliswa, kwaye ulwalathiso lwentsimi yemagnethi lulawulo lwesandla sasekunene. Masithi i-loudspeaker idlala i-C kwi-261.6Hz, i-loudspeaker ikhupha i-261.6Hz mechanical wave kwaye ithumela ukulungiswa kwe-C wavelength. I-speaker ivelisa isandi xa i-coil, kunye nefilimu ye-speaker, ikhupha i-mechanical wave, edluliselwa emoyeni ojikelezileyo. [1]
Nangona kunjalo, ngenxa yokuba ubude be-wave yoomatshini obunokuviwa yindlebe yomntu bulinganiselwe, uluhlu lwe-wavevel yi-1.7cm -- 17m (20Hz -- 20 00Hz), ngoko ke inkqubo yesithethi ngokubanzi iya kubekwa kolu luhlu. Izithethi ze-electromagnetic zenziwe ngenkqubo yamandla e-electromagnetic (kuquka: i-magnet voice coil, eyaziwa ngokuba yi-electric coil). Inkqubo ye-mechanical wave (kuquka: i-sound film, oko kukuthi, i-horn diaphragm dust cover wave), inkqubo yokuxhasa (kuquka: i-basin frame, njl.njl.). Isebenza ngendlela efanayo nale ingasentla. Inkqubo yokuguqulwa kwamandla isuka kumandla ombane ukuya kumandla e-magnetic, kwaye emva koko ukusuka kumandla e-magnetic ukuya kumandla e-wave.
Isithethi se-bass kunye nesithethi se-treble, isithethi esiphakathi esinesandi, igagasi elide, ubude bobude, senza iindlebe zabantu zivelise uvakalelo olufudumeleyo, uvakalelo olushushu, kwaye zenze abantu bachwayite, bachwayite, olusetyenziswa rhoqo kwi-KTV, kwibhari, eqongeni nakwezinye iindawo zokuzonwabisa ezibanzi.
