I-Subwoofer Yemoto: Isisekelo Sedili Lokuzwa kanye Nomhlahlandlela Wokuxazulula Izinkinga
Ezweni lomsindo wemoto, i-subwoofer ifana neqhawe elithobekile kodwa elibalulekile elingaphakathi. Ngomsindo wayo ojulile nozwakalayo, ibeka isisekelo sayo yonke ingoma, ithuthukisa umuzwa wokuzwa ojulile nowendlalekile wabagibeli.
Umsebenzi oyinhloko we-subwoofer yemoto
I-subwoofer inesibopho esikhulu sokukhiqiza imisindo ebangeni lemvamisa engu-20Hz - 250Hz. Leli bhendi lemvamisa lithwala isisindo kanye nokucindezeleka okunesigqi somculo, okuyisihluthulelo sokwakha insimu yomsindo ephelele. Iguqula ugesi ube amagagasi omshini, okwenza i-diaphragm idlidlize futhi ikhiqize umsindo ngokuhamba komoya, ifaka umculo nomphefumulo.
Ngokombono wokuhlangenwe nakho kokuzwa, i-subwoofer esezingeni eliphezulu ingathuthukisa kakhulu uthando nomthelela womculo. Uma udlala umculo ojulile njenge-rock noma i-electronic, i-bass enamandla ingenza ukushaya kwedrama "kuqine", imigqa ye-bass ihluke ngokucacile, njengokungathi inothi ngalinye lingathinta inhliziyo ngqo, lidale isimo esithelelanayo kakhulu. Ngesikhathi sokugibela izimoto, ingafihla ngempumelelo imisindo ephansi, njengemisindo yokungqubuzana kwamathayi nomgwaqo, imisindo yokugijima kwenjini, njll., okuvumela abagibeli ukuthi bajabulele umculo endaweni ethule.
Ngokombono wesimiso se-acoustic, izikhulumi ezivamile zinqunyelwe ngobukhulu kanye nezakhiwo zomzimba futhi zinobunzima bokukhiqiza ngempumelelo imisindo ephansi ene-wavelength ende. Kodwa-ke, ama-subwoofers, anama-diaphragm awo amakhulu, imiphetho yokumiswa okuthambile, kanye nezifunda ezinamandla ze-magnetic thrust, kuhlanganiswe nemigodi yeminyango yemoto noma izindawo ezibekelwe zona, angadala ukuguquguquka kwengcindezi okubonakalayo emoyeni. Indlebe yomuntu izwa kakhulu ububanzi bemvamisa engu-80 - 120Hz, okuletha isisindo se-drumbeats kanye nobuqiniso be-bass, ngaphandle kwayo, umculo ubuyoba njengesakhiwo esingenasisekelo, ngisho ne-treble ecacile kakhulu ibingabonakala incane futhi incane.
Amaphutha avamile e-subwoofers yemoto nezindlela zokuxazulula izinkinga
Nakuba i-subwoofer idlala indima ebalulekile, ingase ihlangane namaphutha ahlukahlukene ngesikhathi sokuyisebenzisa. Evame kakhulu ukuthi i-subwoofer ayisebenzi. Izizathu zalokhu ziyahlukahluka, futhi umnikazi angathola imbangela ngokuxazulula inkinga kancane kancane.
Imbangela evamile yale nkinga iphutha lokuxhuma izintambo. Izintambo ze-subwoofer zingase zibe nesekethe ephukile, isekethe esifushane, noma ukuxhumana okungekuhle, njengezintambo ezindala noma ezonakele, noma ama-plug axegayo. Umnikazi angahlola izintambo ezihambisana ne-subwoofer ukuze ahlole izimpawu zomonakalo ezisobala ezintanjeni nokuthi i-plug iphephile yini. Uma kutholakala inkinga yokuxhuma izintambo, ingalungiswa noma ishintshwe njengoba kudingeka.
I-subwoofer ngokwayo nayo ingonakala, okubangela ukuthi yehluleke ukukhiqiza umsindo. Ukusetshenziswa kwesikhathi eside noma umthelela wangaphandle kungabangela ukuthi ikhoyili yezwi ishise, i-diaphragm iqhekeke, njll. Umnikazi angalinganisa inani lokumelana le-subwoofer nge-multimeter. Uma inani lokumelana lingajwayelekile noma i-subwoofer ingasebenzi uma ixhunywe kweminye imishini yomsindo evamile, kungatholakala ukuthi i-subwoofer yonakele futhi idinga ukushintshwa ngentsha. Lapho ukhetha i-subwoofer entsha, naka imingcele yayo kanye nekhwalithi ukuqinisekisa ukuthi ihambisana nohlelo lomsindo lwemoto.
Amaphutha ku-power amplifier nawo angathinta ukusebenza okuvamile kwe-subwoofer. Uma i-power amplifier yehluleka, ayikwazi ukunikeza amandla anele ku-subwoofer, futhi i-subwoofer ngeke ikwazi ukukhiqiza umsindo. Lokhu kudinga abasebenzi abangochwepheshe bokulungisa umsindo ukuze benze ukutholakala nokulungiswa. Abanikazi akufanele bazame ukuyihlukanisa bona ngokwabo, njengoba ingabangela umonakalo omkhulu nakakhulu.
Ngaphezu kwalokho, izilungiselelo zomsindo ezingalungile kanye nama-fuse aqhumile nakho kungabangela ukuthi i-subwoofer yehluleke ukusebenza. Umnikazi angahlola kuqala imenyu yezilungiselelo zesistimu yomsindo yemoto ukuqinisekisa ukuthi ivolumu ye-subwoofer icishiwe noma ibekwe phansi kakhulu; bese ethola i-fuse ehambisanayo yesistimu yomsindo bese ehlola ukuthi iphelele yini. Uma iqhumile, yishintshe nge-fuse enencazelo efanayo.
Amaphuzu abalulekile okufakwa nokugcinwa kwama-subwoofers emoto
Ukuze ugcine i-subwoofer isesimweni esihle sokusebenza, izigaba zokufaka nokulungisa zibalulekile. Ngesikhathi sokufaka, qaphela ukuthi ugweme ukugeleza komoya phakathi kwemigodi yangaphambili neyangemuva, njengoba lokhu kuzokwenza ukuthi amandla aphansi alahleke futhi umsindo ube mncane futhi ube mncane. Ukusebenzisa izinto ze-EVA kuma-pads okuvala kungaxazulula le nkinga ngempumelelo. Iyanwebeka futhi inamandla okusekela, angasonga kahle unqenqema lwesipikha futhi agcwalise izikhala, okwenza i-bass iqine futhi ibe nesisindo.
Ngesikhathi sokusebenzisa nsuku zonke, gwema ukudlala umculo ngomsindo ophezulu isikhathi eside ukuze uvimbele ukusheshisa ukuguga nokulimala kwesipikha. Ngesikhathi esifanayo, hlola njalo izintambo zesipikha nama-plug ukuqinisekisa ukuxhumana okuphephile. Uma imoto idlula ezindaweni ezinamanzi noma ishayelwa endaweni enomswakama isikhathi eside, hlola ngokushesha ukuthi isipikha simanzi yini. Uma kudingeka, yenza ukwelashwa kokomisa.
I-subwoofer yemoto iyingxenye ebalulekile yesistimu yomsindo wemoto. Ayigcini nje ngokuthuthukisa ikhwalithi yomculo kodwa futhi iletha okuhlangenwe nakho okumnandi kokuzwa kubashayeli nabagibeli. Ukuqonda umsebenzi wayo, ukwazi izindlela zokuxazulula izinkinga zamaphutha avamile, nokwenza umsebenzi omuhle wokufaka nokulungisa kungaqinisekisa ukuthi i-subwoofer ihlala isesimweni esihle kakhulu ngaso sonke isikhathi, inezela izingoma ezinhle ohambweni ngalunye.
