Kutheni ndifuna isihlungi se-subwoofer?

Abaninzi be-movie abalandeli bafuna ukuba nendawo yokuzonwabisa yasekhaya, kodwa akusiyo wonke umntu onokukwazi ukufumana loo nto. Wonke umntu uphuma kule meko ngendlela yakhe: umntu uza kufumana izivakalisi ezilula zesiTshayina, umntu uya kulungelelanisa ama-acoustics aseSoviet kwi-bass, kodwa abaphambili kakhulu abawazi ulwazi kwirejineli yomsakazo baya kwakha umbane we-subwoofer. Ngokukodwa kuba kulula.

Ulwazi jikelele

Khawucinge ukuba yi-subwoofer evamile. Enyanisweni, oku kuluhlu olulula olusebenzayo lwefayili , efumana iimpawu ezisuka kumgca wendlela (i-right and left), i-amplifier kunye ne-woofer. Kule nqaku, siza kujonga kwizinto ezinzima kakhulu kwisixhobo-isiphaluka esikuvumela ukuba wakhe isilathisi esiphantsi kwe-subwoofer ngokwakho. Ezi zixhobo zivelisa ii-frequencies ezingadluli kwi-40 Hertz. Ziyasetyenziswa ngokubambisana neentetho ze-satellites ezincinci. I-Subwoofers isebenzayo kwaye ingenzi. Ezi zilandelayo ziyiNtloko ye-frequency-frequency efakwe kwi-amplifier efanayo. Ezi zixhobo azizimeli kwaye azithandi. Ingxaki eyahlukileyo - okokuqala. Kwizixhobo ezinjalo, ukwahlula ngekhompyutheni ephantsi kwe-subwoofer kunye ne- amplifier yamandla eyahlukileyo eyahlula i-bass ukusuka kumqondiso othunyelwa kwiintetho eziphambili ngqo kwindawo yokutya, apho ukucoca kwesi sigxina kuya kufaka izinga eliphantsi kakhulu lokungahambisani nomnxeba, xa kuthelekiswa nokucoca umbane wamandla okuvelisa. Ukongeza i-amplifier eyahlukeneyo kwisiteshi se-subwoofer kuya kunyusela kakhulu ububanzi obushukumisayo, kunye nokukhululeka phakathi kwiphakathi kunye ne-high-frequency amplifier kumthwalo owongezelelweyo.

Isihlungi se-Subwoofer: amacebo

Umfundi unikezwa ngeendlela ezihlukeneyo zezicwangciso zeso sixhobo sokuqwalasela. Isicwangciso sokuqala sikhuthaza isihlungi esilula se-subwoofer, esenziwe ngendlela ye-adder kwi-transistor enye. Umgangatho ozwakalayo omsindo kunye nesixhobo asiyi kufezwa, kodwa, ngenxa yobulula bayo, kufezekile ukuqala koomatshini benomathotholo bentengiso. Kodwa ifayile ye-subwoofer, echazwe kule mibini iinguqulelo ezilandelayo, impumelelo enkulu ibonakaliswe kwisixhobo esinempawu ezibalaseleyo. Ezi zixhobo zifakwe ngokuthe ngqo emva komgca wendlela yomthombo kunye negalelo lomkhulisi wamandla. Isihlungi se-Subwoofer Ifakwe ngomsindo ophantsi, ukusetyenziswa kwamandla aphantsi, kwakunye neendidi ezahlukeneyo zokunikezela kwamandla.

Isiphelo

Ukucaphula, masithi ukuba ukongeza i-subwoofer esebenzayo kunciphisa kakhulu umda ophantsi wee-frequencies, owandisa ukuhlambuluka kwesandi kumaxesha aphakathi kwaye unikeze umthamo ophezulu ngaphandle kokuphazamiseka. Ukuqhawula ukusuka kwimbonakaliso yesalathisi esakhiweyo, ukufika kuma-satellites, ii-frequencies eziphantsi zibenza bakwazi ukuvakala ukucoceka nokuphakamisa. Oku kungenxa yokuba i-cone yekhanda eliphantsi kwe-frequency ayigxininisi nge-amplitude enkulu, uzama ukuvelisa i-bass kwaye ngaloo ndlela ilahlekisa umqondiso.
