I-Subwoofers ibe yinto eyimfuneko kwiinkqubo zeaudio zanamhlanje, umculo ophakamisayo, iimuvi, kunye namava okudlala kunye ne-bass yabo enzulu, enomsindo. Ukuqonda izinto ezintsonkothileyo zendlela ezisebenza ngayo ii-subwoofers, izibonelelo zazo kunye nezithintelo, kunye nendlela yokukhetha kunye nokuzisebenzisa ngokufanelekileyo kunokuphucula kakhulu amava akho okumamela. Eli nqaku lijonga kuyo yonke into odinga ukuyazi malunga ne-subwoofers, ibonelela ngolwazi kubo bobabini i-audiophiles kunye nabaphulaphuli abaqhelekileyo ngokufanayo.

Yintoni i-subwoofer?
I-subwoofer luhlobo lwesandisi-lizwi esenzelwe ukuvelisa iifrikhwensi zomsindo ezisezantsi ezaziwa ngokuba yi-bass kunye ne-sub-bass, engaphantsi kunento enokuthi ivelise izithethi eziqhelekileyo. I-Subwoofers igubungela uluhlu oluqhelekileyo ukusuka malunga ne-20 Hz ukuya kwi-200 Hz kwiimveliso zabathengi, ngaphaya apho izithethi eziqhelekileyo zithatha khona. Ziyinxalenye ebalulekileyo kwiinkqubo zesandi esingqongileyo kunye nokufikelela kumava okumamela apheleleyo, ngakumbi kwiithiyetha zasekhaya, iisistim zomsindo wemoto, kunye neenkqubo zeedilesi zoluntu.
I-Subwoofers iza ngobukhulu obahlukeneyo, ukusuka kwiiyunithi ezihlangeneyo ezinokufihlwa kude phantsi kwefenitshala ukuya kwiimodeli ezinkulu ezisemgangathweni ezinokuthi zibe ngundoqo wokuseta umsindo. Uyilo lwabo lubandakanya umqhubi omkhulu (inxalenye yesithethi esishukumayo ukwenza isandi) egcinwe kwikhabhinethi eyenzelwe ngokukodwa ukunyusa imveliso yesandi esisezantsi. Olu gxininiso kwiifrikhwensi ezisezantsi luvumela i-subwoofers ukuba ivelise izandi ezinzulu, ezibethayo onokuthi uzive rhoqo njengokuva.
Isebenza njani i-subwoofer?
I-Subwoofers isebenza ngokuguqula imiqondiso yombane ibe yintshukumo yomzimba ukuvelisa amaza omsindo. Intliziyo ye-subwoofer ngumqhubi wayo okanye i-woofer-i-diaphragm enkulu ehamba ngasemva naphambili ukutyhala umoya kunye nokudala amaza omsindo. Le ntshukumo iveliswa yinkqubo ye-electromagnetic ebandakanya ikhoyili yelizwi exhonywe kumhlaba wemagnethi. Xa isignali yomsindo idluliswa kwikhoyili, ibangela intsimi yamagnetic edibana nemagnethi engapheliyo ejikelezayo, ebangela ukuba ikhoyili, kwaye ngaloo ndlela i-diaphragm, ihambe.
Uyilo lwendawo ebiyelweyo ye-subwoofer idlala indima ebalulekileyo ekusebenzeni kwayo. Kukho iintlobo ezininzi ze-subwoofer ezivaliweyo, ezibandakanya itywina, i-ported, kunye ne-bandpass, nganye inikezela ngeempawu ezahlukeneyo ngokusebenza kakuhle, ukuphendula rhoqo, kunye nomgangatho wesandi ngokubanzi. Umthamo we-enclosure kunye nokumila zibalwa ngononophelo ukuze zihambelane neenkcukacha zomqhubi ukunyusa ukusebenza kakuhle kwenkqubo kunye nokunciphisa ukugqwesa.
Izibonelelo kunye neengxaki ze-subwoofer
I-Subwoofers izisa uluhlu lweenzuzo kwinkqubo yomsindo. Banikezela ngobunzulu kunye nobutyebi kwisandi esinokuthi izithethi ezincinci zingakwazi ukufezekisa, zivumela abaphulaphuli ukuba bafumane i-spectrum epheleleyo yomculo kunye neengoma zesandi, kuquka i-bass frequencies ephantsi. Oku kunokudala amava okumamela okuntywilayo, nokuba ubukele imuvi, umamele umculo, okanye udlala umdlalo wevidiyo. Ukongeza, ngokuphatha i-bass frequencies, ii-subwoofers zikhulula izithethi ezincinci kwinkqubo ekuveliseni ezi zandi zifunayo, ezikhokelela ekucaceni, iinkcukacha ezingakumbi phakathi kunye nezandi eziphezulu.
Nangona kunjalo, ii-subwoofers nazo zineengxaki zazo. Zinokuba zikhulu kwaye zibe nzima ukudibanisa kwiindawo ezincinci zokuhlala ngobuhle. Ukubekwa ngokufanelekileyo kubalulekile ukuze usebenze kakuhle, kwaye ukufumana indawo efanelekileyo kunokuba lucelomngeni. Ngaphezu koko, ukuyilwa kakubi okanye ukuseta ngokungalunganga i-subwoofers kunokukhokelela kwi-boomy okanye i-bass engalawulekiyo egqithisa yonke i-audio spectrum, kunokuba iyincedise.
Indlela yokukhetha i-subwoofer
Ukukhetha i-subwoofer efanelekileyo kubandakanya ukuqwalasela izinto ezininzi, kubandakanywa ubungakanani, amandla, uhlobo lwe-enclosure, kunye nokukhethwa koqhagamshelwano. Ubungakanani begumbi kunye nokusetyenziswa okuphambili kwe-subwoofer (umculo, iifilimu, okanye into encinci yezinto zonke) ziya kumisela amandla kunye nobukhulu be-subwoofer oyifunayo. Amagumbi amakhulu kunye nabo bafuna amava afana ne-cinema banokuzuza kwii-subwoofers ezinkulu, ezinamandla ngakumbi, ngelixa amagumbi amancinci okanye abo banomdla kakhulu kumculo banokukhetha iyunithi ehlangeneyo, engaphantsi kwamandla.
Uhlobo lwendawo ebiyelweyo lukwayingqwalasela ebalulekileyo. Izivalo ezitywiniweyo zibonelela ngokungqongqo, ii-bass ezichaneke ngakumbi, ngelixa i-ported kunye ne-bandpass ezivaliweyo zinokuvelisa ivolyum eninzi kunye namava e-bass agcweleyo kodwa zinokuncama ukuchaneka okuthile. Ukongezelela, cinga ukuba ufuna i-subwoofer enamandla (ene-amplifier eyakhelwe ngaphakathi) okanye i-subwoofer engabonakaliyo (efuna i-amplifier yangaphandle), ugcine engqondweni iinketho zokuxhuma kunye nenkqubo yakho yomsindo ekhoyo.
Uyisebenzisa njani i-subwoofer
Ukucwangcisa ngokufanelekileyo kunye nokusebenzisa i-subwoofer kunokuphucula kakhulu ukusebenza kwayo. Ukubekwa ngundoqo; indawo efanelekileyo ixhomekeke kwi-acoustics yegumbi kunye noyilo. Zama ngeendawo ezahlukeneyo, ukhumbula ukuba iikona zinokuyandisa i-bass kodwa zinokuyibhuqa. Nje ukuba ufumene indawo efanelekileyo, lungisa i-frequency crossover-indawo apho i-subwoofer yakho ithatha imisebenzi ye-bass kwizithethi zakho-ukuqinisekisa inguqu yomsindo engenamthungo. Okokugqibela, lungisa ivolumu kunye nolawulo lwesigaba ukuze lutshatise yonke inkqubo yakho, ujolise kwisandi esilungeleleneyo esidibanisa i-bass kakuhle kunye nombindi kunye nophezulu.
Isiphelo:
I-Subwoofers zizixhobo ezinamandla kuyo nayiphi na isethingi yomsindo, ekwazi ukuzisa ubunzulu, ubutyebi, kunye nokuntywiliselwa kumava akho okumamela. Ukuqonda indlela asebenza ngayo, iingenelo kunye nokusikelwa kwawo umda, nendlela yokukhetha nokusebenzisa ngokufanelekileyo kunokukunceda uvule amandla abo apheleleyo. Nokuba ungumntu othanda ukulalela umculo ofuna isandi esigqibeleleyo okanye ujonge nje ukomeleza inkqubo yokuzonwabisa yasekhaya, i-subwoofer ekhethwe kakuhle kwaye iqwalaselwe kakuhle inokwenza umahluko wehlabathi.
