Nokuba udlala i-drum solos emotweni yakho, ulungiselela inkqubo yakho yethiyetha yasekhaya ukuze ubukele imuvi entsha ye-Avengers, okanye wakha inkqubo yestereo yebhendi yakho, mhlawumbi ufuna loo bass inzulu nemnandi. Ukuze ufumane esi sandi, udinga i-subwoofer.

I-subwoofer luhlobo lwesithethi esivelisa i-bass efana ne-bass kunye ne-sub-bass. I-subwoofer iya kuthatha isignali yesandi esezantsi kwaye iyiguqule ibe sisandi esingenakuveliswa yi-subwoofer.

Ukuba inkqubo yakho yesithethi icwangciswe ngokuchanekileyo, ungaziva isandi esinzulu nesityebileyo. Isebenza njani i-subwoofer? zeziphi ii-subwoofer ezilungileyo, kwaye ngaba zinefuthe elingako kwinkqubo yakho yesandi iyonke? Nantsi into ekufuneka uyazi.

Yintoni ii-subwoofer?

Ukuba une-subwoofer, kufuneka kubekho enye i-subwoofer, akunjalo? akunjalo. Uninzi lwee-woofers okanye izithethi eziqhelekileyo zinokuvelisa isandi esifikelela kwi-50 Hz kuphela. I-subwoofer ivelisa isandi esiphantsi esifikelela kwi-20 Hz. Ngenxa yoko, igama elithi "subwoofer" livela kwisandi esiphantsi esenziwa zizinja xa zikhonkotha.

Nangona umahluko phakathi komlinganiselo we-50 Hz wezithethi ezininzi kunye nomlinganiselo we-20 Hz we-subwoofer usenokuvakala ungabalulekanga, iziphumo ziyabonakala. I-subwoofer ikuvumela ukuba uzive i-bass kwingoma nakwimuvi, okanye nantoni na oyimameleyo. Okukhona impendulo ye-subwoofer iphantsi, kokukhona i-bass iya kuba namandla kwaye ibe mnandi ngakumbi.

Ekubeni la mathoni esezantsi kakhulu, abanye abantu abakwazi nokuva i-bass kwi-subwoofer. Yiyo loo nto i-feel component ye-subwoofer ibaluleke kangaka.

Iindlebe ezincinci nezisempilweni zinokuva izandi eziphantsi njenge-20 Hz, oko kuthetha ukuba iindlebe zabantu abaneminyaka ephakathi ngamanye amaxesha ziyasokola ukuva izandi ezinzulu kangaka. Nge-subwoofer, ngokuqinisekileyo uya kuziva ukungcangcazela nokuba awukwazi ukukuva.

Isebenza njani i-subwoofer?

I-subwoofer iqhagamshela kwezinye izithethi ezikwinkqubo yesandi epheleleyo. Ukuba udlala umculo ekhaya, mhlawumbi une-subwoofer eqhagamshelwe kwisamkeli sakho sesandi. Xa umculo udlalwa ngezithethi, uthumela izandi eziphantsi kwi-subwoofer ukuze ziphinde zivele ngokufanelekileyo.

Xa kufikwa ekuqondeni indlela ezisebenza ngayo ii-subwoofer, ungadibana neentlobo ezisebenzayo nezingasebenziyo. I-subwoofer esebenzayo ine-amplifier eyakhelwe ngaphakathi. Ii-subwoofer ezingasebenziyo zifuna i-amplifier yangaphandle. Ukuba ukhetha ukusebenzisa i-subwoofer esebenzayo, kuya kufuneka uthenge intambo ye-subwoofer, njengoko kuya kufuneka uyiqhagamshele kwi-receiver yenkqubo yesandi, njengoko kuchaziwe apha ngasentla.

Uza kuqaphela ukuba kwinkqubo yesandi yethiyetha yasekhaya, i-subwoofer sesona sithethi sikhulu. Ngaba esikhudlwana singcono? Ewe! Okukhona isithethi se-subwoofer sikhulu, kokukhona isandi sinzulu. Zizithethi ezinkulu kuphela ezinokuvelisa isandi esinzulu osivayo kwi-subwoofer.

Kuthekani ngokungcangcazela? Kusebenza njani oku? Ukusebenza kakuhle kwe-subwoofer kuxhomekeke kakhulu kwindawo ekuyo. Iinjineli zesandi ezingoochwephesha zicebisa ukubeka ii-subwoofer:

Phantsi kwefenitshala. Ukuba ufuna ngokwenene ukuziva ukungcangcazela kwesandi esinzulu nesityebileyo semuvi okanye ingoma yomculo, ukuyibeka phantsi kwefenitshala yakho, njengesofa okanye isitulo, kunokuphucula ezo mvakalelo.

ecaleni kodonga. Beka eyakhoibhokisi ye-subwooferecaleni kodonga ukuze isandi sivakale eludongeni kwaye sinyuse i-bass.

Indlela yokukhetha i-subwoofer engcono kakhulu

Njengezithethi eziqhelekileyo, iinkcukacha ze-subwoofer zinokuchaphazela inkqubo yokuthenga. Ngokuxhomekeke kwinto oyifunayo, nantsi into ekufuneka uyijonge.

Uluhlu lweeFrequency

Isandi esiphantsi kakhulu se-subwoofer sisandi esiphantsi kakhulu esinokuveliswa ngumqhubi wesithethi. Isandi esiphezulu kakhulu sisandi esiphezulu esinokuveliswa ngumqhubi. Ii-subwoofer ezilungileyo zivelisa isandi esifikelela kwi-20 Hz, kodwa umntu kufuneka ajonge uluhlu lwesandi ukuze abone ukuba i-subwoofer ingena njani kwinkqubo yestereo iyonke.

Uvelwano

Xa ujonga iimpawu zee-subwoofers ezidumileyo, jonga uvakalelo. Oku kubonisa ukuba kufuneka amandla angakanani ukuvelisa isandi esithile. Okukhona uvakalelo luphezulu, kokukhona amandla amancinci afunekayo ukuvelisa i-bass efanayo nespika esikwinqanaba elifanayo.

Uhlobo lwekhabhinethi

Ii-subwoofers ezivalekileyo esele zakhelwe kwibhokisi ye-subwoofer zidla ngokukunika isandi esinzulu nesipheleleyo kunesingenalo isandi. Ityala elineembobo lingcono kwizandi ezivakalayo, kodwa kungekhona isandi esinzulu.

Ukunganyamezelani

Impedance, elinganiswa ngee-ohms, inxulumene nokuxhathisa kwesixhobo kumbane ngokusebenzisa umthombo wesandi. Uninzi lwee-subwoofer zinempedance ye-4 ohms, kodwa ungafumana nee-subwoofer ze-2 ohm kunye ne-8 ohm.

Ikhoyili yelizwi

Uninzi lwee-subwoofers ziza ne-voice coil enye, kodwa abantu abanomdla wokusebenzisa i-audio abanamava ngokwenene okanye abanomdla badla ngokukhetha ii-subwoofers ezimbini ze-voice coil. Ngee-voice coil ezimbini, ungaqhagamshela inkqubo yesandi njengoko ubona kufanelekile.

Amandla

Xa ukhetha i-subwoofer engcono, qiniseka ukuba ujonge amandla alinganisiweyo. Kwi-subwoofer, amandla e-RMS alinganisiweyo abaluleke ngakumbi kune-peak power alinganisiweyo. Oku kungenxa yokuba ilinganisa amandla aqhubekayo kunokuba ibe ngamandla aphezulu. Ukuba sele unayo i-amplifier, qiniseka ukuba i-subwoofer oyijongileyo inokusingatha loo mandla aphumayo.
