Kwihlabathi letekhnoloji yomsindo, amacandelo ambalwa ahlonitshwa kwaye abaluleke njengenkqubo yesandi ye-subwoofer. Nokuba ungumdlali we-audiophile, umboniso bhanyabhanya, okanye umphulaphuli nje oqhelekileyo, ii-subwoofers zidlala indima ephambili ekunikezeni amava omsindo antywilayo. Ke yintoni malunga nee-subwoofers ezenza zivakale zinamandla? Kweli nqaku, siza kuphonononga ubuchwephesha obusemva kwe-subwoofers, ifuthe abanalo kumgangatho wesandi, kwaye kutheni kufuneka babenayo nayiphi na.inkqubo yesandi enzulu.

Ukuqonda i-Subwoofers

I-subwoofer sisithethi esilungiselelwe ngokukodwa ukuvelisa izandi ze-low-frequency, ngokuqhelekileyo kuluhlu lwe-20 Hz ukuya kwi-200 Hz. Ezi frikhwensi zisezantsi zihlala zibizwa ngokuba yi-bass, kwaye zibalulekile ekudaleni amava esandi esipheleleyo. Ngokungafaniyo nezithethi eziqhelekileyo, eziphethe izandi eziphakathi kunye nephezulu-zandi, i-subwoofers igxininise ekupheleni kwe-audio spectrum, eyimfuneko kwiindidi ezifana ne-hip-hop,umculo womdaniso we-elektroniki, kunye nemiboniso bhanyabhanya enentshukumo.

IiSubwoofers ziyilelwe ukukhulisa amandla azo okuvelisa isandi esinzulu, esivakalayo. Uninzi lwee-subwoofers zisebenzisa iicones ezinkulu kunye neemagnethi ezinamandla ukuhambisa umoya ngokufanelekileyo ukwenza ii-vibrations esizibona njenge-bass. Olu yilo lubenza bakwazi ukuvelisa amaza omsindo angangxoli nje kuphela, kodwa azele kwaye antywiliselwe.

IFiziksi yeZandi

Ukuqonda ukuba i-subwoofers inokuvelisa njaniisandi esinamandla, kufuneka singene kwi-physics yamaza esandi. Isandi liza elinomatshini elihamba ngeentshukumo zomoya (okanye ezinye imidiya). Ubungakanani bokungcangcazela bumisela isandi sesandi, ngelixa i-amplitude imisela umthamo wesandi.

Izandi zezandi ezisezantsi, njengalezo eziveliswa yi-subwoofer, zinexesha elide kwaye zifuna amandla amaninzi okuvelisa. Ngenxa yoku, ii-subwoofers zixhotyiswe ngabaqhubi abakhulu kunye ne-amplifiers ezinamandla kunezithethi eziqhelekileyo. Ukukwazi ukuhambisa umthamo omkhulu womoya kunika ii-subwoofers impembelelo yazo ekhethekileyo kunye nobunzulu.

Impembelelo yeemvakalelo ze-bass

Esinye sezizathu zokuba isandi se-subwoofer sinamandla kakhulu kukuba sishukumisa intliziyo. Iifrikhwensi ezisezantsi zinekhono elikhethekileyo lokunxibelelana nemizimba yethu, zenza amava oluvo azive eyinyani njengokuyiva. Oku kuyinyani ngakumbi kumculo ophilayo, apho i-bass inokubonakala ifikelela kanye esifubeni sakho, iphakamisa amava ngokubanzi.

Kwimiboniso bhanyabhanya kunye nemidlalo, i-subwoofer inokunyusa uxinzelelo lweemvakalelo kwindawo. Khawucinge ngesandi sokudubula, okanye ukubetha kwentliziyo ngexesha lomzuzu onzima; ezi zandi zenzelwe ukuvakala nzulu kubaphulaphuli. I-subwoofer inokuphinda ivelise la maza aphantsi, yongeza ubunzulu kwi-soundscape, okwenza amava antywilise kwaye abandakanyeke.

Indima ye-subwoofers kwiinkqubo zethiyetha yasekhaya

Ii-subwoofers zibalulekile kwi-ainkqubo yethiyetha yasekhaya. Banikezela ngenkxaso ye-frequency ephantsi, ebaluleke kakhulu kwiimuvi zesenzo, ezizaliswe ngokudubula kunye nemiphumo yesandi esinzulu. Ngaphandle kwe-subwoofer, ezi zandi zinokubonakala zithe tyaba kwaye zingenayo impembelelo yokungcangcazela kwentliziyo.

Ukongeza, i-subwoofers inceda ukulungelelanisa isandi esipheleleyo senkqubo yethiyetha yasekhaya. Ngokuphatha ii-frequency eziphantsi, zivumela izithethi eziphambili ukuba zigxininise kwi-middle-and-high-frequency ranges, okubangelwa isandi esicacileyo, esicacileyo. Olu lwahlulo lwamatyeli aluphuculi nje ukucaca kuphela, kodwa lukwanqanda ukugqwetheka kumava amnandi okuphulaphula.

Ukukhetha OkulungileyoI-Subwoofer Sound System

Kukho izinto ezininzi ekufuneka ziqwalaselwe xa ukhetha inkqubo yesandi ye-subwoofer. Ubungakanani begumbi, uhlobo lomxholo we-audio owuthandayo, kunye nohlahlo lwabiwo-mali lwakho luyingqwalasela ebalulekileyo. Igumbi elikhulu linokufuna i-subwoofer enamandla ngakumbi ukuze igcwalise indawo ngesandi, ngelixa igumbi elincinci linokufuna imodeli ehlangeneyo esekho.ihambisa i-bass enomtsalane.

Ukongeza, uhlobo lwe-subwoofer, nokuba i-passive okanye inamandla, iya kuchaphazela amava akho. I-subwoofers ene-powered ine-amplifiers eyakhelweyo, eyenza kube lula ukuseta kunye nokusetyenziswa. I-Passive subwoofers, kwelinye icala, ifuna iiamplifier yangaphandlekodwa unikeze iinketho ezininzi zokwenza ngokwezifiso zeaudiophiles.

Ukuququmbela

Kukho izizathu ezininzi zokuba kutheni i-subwoofer ivakala inamandla. Ukukwazi kwayo ukuvelisa amaza aphantsi kudala amava omsindo atyebileyo nantywilisayo adibana nomphulaphuli kwinqanaba leemvakalelo kunye nomzimba. Nokuba ubukele imuvi, uphulaphule umculo, okanye udlala imidlalo yevidiyo, inkqubo yesandi esemgangathweni ye-subwoofer inokuphakamisa amava akho, iyenze ibandakanyeke ngakumbi kwaye yonwabe.

Njengoko itekhnoloji iqhubeka nokuvela, ii-subwoofers ziye zaphucuka ngakumbi, zixhotyiswe ngeempawu ezinjengokuqhagamshelwa ngaphandle kwamacingo kunye nokuhlengahlengiswa kwegumbi. Nangona kunjalo, isibheno esisisiseko se-subwoofer sihlala sifana: amandla ayo okuhambisa isandi esinzulu, esichukumisayo esichukumisayo nesishukumisayo. Kuba nabani na ozimiseleyo malunga neaudio, ukutyala imali kwi-ainkqubo yesandi ye-subwoofer ekumgangatho ophezuluayilokhetho nje, luyimfuneko.
