Ibhokisi le-subwoofer liwuthinta kanjani umsindo?

Kumsindo wemoto, kunezinketho eziningi zamabhokisi e-acoustic design. Ngakho-ke, abaqalayo abaningi abazi ukuthi yikuphi okungcono ukukhetha. Izinhlobo ezidume kakhulu zamabhokisi e-subwoofer yibhokisi elivaliwe kanye ne-inverter yesigaba.

Futhi kukhona imiklamo efana ne-bandpass, i-quarter-wave resonator, i-free-air nezinye, kodwa uma izinhlelo zokwakha zisetshenziswa kakhulu ngenxa yezizathu ezihlukahlukene. Kukumnikazi wesipikha ukunquma ukuthi iyiphi ibhokisi le-subwoofer elizokhethwa ngokusekelwe ezidingweni zomsindo nolwazi.

Sikweluleka ukuthi unake isihloko esivela kuso okuqukethwe okungcono ukwenza ibhokisi le-subwoofer. Sibonise ngokucacile ukuthi ukuqina kwebhokisi kuthinta kanjani ikhwalithi nomthamo we-bass.

ibhokisi elivaliwe

Lolu hlobo lokuklama lulula kakhulu. Ibhokisi elivaliwe le-subwoofer kulula ukubala nokuhlanganisa. Idizayini yayo iyibhokisi lezindonga ezimbalwa, ngokuvamile eziyisi-6.

Izinzuzo ze-ZY:

1. Ukubala okulula;
2. Ukuhlanganiswa okulula;
3. Ukususwa okuncane kwebhokisi eliqediwe, ngakho-ke ukubumbana;
4. Izici ezinhle zokucabanga;
5. Ibhesi esheshayo necacile. Idlala kahle amathrekhi ekilabhu.

Ububi bebhokisi elivaliwe bubodwa, kodwa ngezinye izikhathi bunquma. Lolu hlobo lokuklama lunezinga eliphansi kakhulu lokusebenza kahle elihlobene namanye amabhokisi. Ibhokisi elivaliwe alibafanele labo abafuna umfutho womsindo ophezulu.

Kodwa-ke, ilungele abalandeli be-rock, umculo we-club, i-jazz nokunye okunjalo. Uma umuntu efuna ama-bass, kodwa udinga isikhala esiqwini, ibhokisi elivaliwe lilungile. Ibhokisi elivaliwe lizodlala kabi uma ivolumu engalungile ikhethiwe. Imuphi umthamo webhokisi odingekayo kulolu hlobo lokuklama sekuyisikhathi eside kunqunywa abantu abanolwazi kumsindo wemoto ngokusebenzisa izibalo nokuhlola. Ukukhethwa kwevolumu kuzoncika kusayizi we-subwoofer.

Ngokuvamile kuba khona izikhulumi zalezi osayizi: 6, 8, 10, 12, 15, 18 amayintshi. Kodwa ungathola futhi izikhulumi zamanye amasayizi, njengomthetho, asetshenziswa kakhulu ekufakweni. Ama-Subwoofers anobubanzi obungama-intshi angu-6 akhiqizwa izinkampani eziningana futhi awavamile ekufakweni. Abantu abaningi bakhetha izikhulumi ezinobubanzi obungamasentimitha angu-8-18. Abanye abantu banikeza ububanzi be-subwoofer ngamasentimitha, okungalungile ngokuphelele. Ngomsindo wemoto wochwepheshe, kuyisiko ukuveza ubukhulu ngamayintshi.

Ivolumu enconyiwe yebhokisi elivaliwe le-subwoofer:

• I-subwoofer engu-8-intshi (20 cm) idinga amalitha angu-8-12 wevolumu yenetha,
• ngo-10-intshi (25 cm) 13-23 amalitha wevolumu enetha,
• ngo-12-intshi (30 cm) 24-37 amalitha wevolumu enetha,
• ngo-15" (38 cm) 38-57-litre wevolumu yenetha
• kanti kweye-intshi engu-18 (46 cm) eyodwa, kuzodingeka amalitha angu-58-80.

Ivolumu inikezwa cishe, ngoba isikhulumi ngasinye udinga ukukhetha ivolumu ethile ngokusekelwe ezicini zayo. Ukusethwa kwebhokisi elivaliwe kuzoncika kumthamo walo. Ivolumu yebhokisi inkulu, imvamisa yokulungisa yebhokisi iphansi, i-bass izoba mnene. Ivolumu encane yebhokisi, ukuphakama kwemvamisa yebhokisi, i-bass izocaca futhi isheshe. Ungakhulisi noma unciphise ivolumu kakhulu, njengoba lokhu kugcwele imiphumela. Lapho ubala ibhokisi, bambelela kuvolumu enqunywe ngenhla. Uma kukhona ukusesha kwevolumu, khona-ke i-bass izoba engacacile, engaqondakali. Uma ivolumu inganele, khona-ke i-bass izoshesha kakhulu futhi "isando" ezindlebeni ngomqondo omubi kakhulu wegama.

Okuningi kuncike kuzilungiselelo zebhokisi, kodwa alikho iphuzu elibalulekile "Ukusethwa komsakazo".

I-inverter yesikhala

Lolu hlobo lomklamo lunzima kakhulu ukubala nokwakha. Umklamo wayo uhluke kakhulu ebhokisini elivaliwe. Nokho, inezinzuzo, okuyilezi:

1. Izinga eliphezulu ukusebenza kahle. I-inverter yesigaba izokhiqiza amaza aphansi kakhulu kakhulu kunebhokisi elivaliwe;
2. Simple hull ukubala;
3. Ukumisa kabusha uma kunesidingo. Lokhu kubaluleke kakhulu kwabaqalayo;
4. Ukupholisa okuhle kwesipikha.

Futhi, isiguquli sesigaba sibuye sibe nokubi, inani lazo likhulu kunele-WL. Ngakho i-cons:

• I-PHI inomsindo omkhulu kune-WL, kodwa i-bass lapha ayisacacile futhi iyashesha;
• Ubukhulu bebhokisi le-FI likhulu kakhulu uma liqhathaniswa ne-ZYa;
• Umthamo omkhulu. Ngenxa yalokhu, ibhokisi eliqediwe lizothatha indawo eyengeziwe esiqwini.

Ngokusekelwe ebuhleni nasekubi, ungaqonda ukuthi amabhokisi e-PHI asetshenziswa kuphi. Imvamisa zisetshenziswa ekufakweni lapho kudingeka khona ama-bass aphezulu naphinyiselwe. I-inverter yesigaba ifanele abalaleli banoma yimuphi umculo we-rap, electronic and club. Futhi kufanelekile kulabo abangadingi isikhala samahhala esiqwini, njengoba ibhokisi lizothatha cishe yonke indawo.

Ibhokisi le-FI lizokusiza ukuthi uthole amabhesi amaningi kunaku-WL kusuka kusipika esiwububanzi obuncane. Nokho, lokhu kuzodinga isikhala esiningi.

Imuphi umthamo webhokisi odingekayo ku-inverter yesigaba?

• ku-subwoofer enobubanzi obungama-intshi angu-8 (20 cm), uzodinga amalitha angu-20-33 wevolumu enetha;
• isipikha esingu-10-intshi (25 cm) - 34-46 amalitha,
• ngo-12-intshi (30 cm) - 47-78 amalitha,
• ngo-15-intshi (38 cm) - 79-120 amalitha
• kanye ne-subwoofer engu-18 inch (46 cm) udinga amalitha angu-120-170.

Njengasendabeni ye-ZYa, izinombolo ezingalungile zinikezwa lapha. Kodwa-ke, esimweni se-FI, ungakwazi "ukudlala" ngevolumu futhi uthathe inani elingaphansi kwalokhu okunconyiwe, uthole ukuthi iyiphi ivolumu i-subwoofer edlala kangcono. Kodwa ungakhulisi noma unciphise ivolumu kakhulu, lokhu kungaholela ekulahlekelweni kwamandla kanye nokwehluleka kwesipika. Kungcono ukuthembela ezincomo zomkhiqizi we-subwoofer.

Yini enquma ukulungiselelwa kwebhokisi le-FI

Umthamo omkhulu webhokisi, imvamisa yokulungisa izoba ephansi, isivinini se-bass sizokwehla. Uma udinga imvamisa ephakeme, khona-ke umthamo kufanele uncishiswe. Uma isilinganiso sakho samandla we-amplifier sidlula isilinganiso sesipikha, ngakho-ke kuyanconywa ukwenza ivolumu ibe mncane. Lokhu kuyadingeka ukuze kusatshalaliswe umthwalo kusipika futhi uvimbele ukuthi ungadluli ukushaya. Uma i-amplifier ibuthakathaka kunesipika, ngakho-ke sincoma ukwenza umthamo webhokisi ube mkhulu kancane. Lokhu kunxephezela umthamo ngenxa yokuntuleka kwamandla.

Indawo yechweba kufanele futhi incike kuvolumu. Amanani amaphakathi wendawo yembobo yesipika ami kanje:

ku-subwoofer engu-8-intshi, kuzodingeka u-60-115 sq. cm,

ngo-10-intshi - 100-160 sq. cm,

ngo-12-intshi - 140-270 sq. cm,

ngo-15-intshi - 240-420 sq. cm,

ngo-18-intshi - 360-580 sq. cm.

Ubude bembobo buphinde buthinte imvamisa yokushuna yebhokisi le-subwoofer, uma imbobo iba yinde, isethingi yebhokisi iphansi, imbobo ibe mfishane, ngokulandelana, imvamisa yokushuna iphezulu. Lapho ubala ibhokisi le-subwoofer, okokuqala, udinga ukuzijwayeza ngezici zesikhulumi kanye nemingcele yebhokisi elinconyiwe. Kwezinye izimo, umenzi uncoma imingcele yebhokisi ehluke ngokuphelele kunaleyo enikezwe esihlokweni. Isikhulumi singase sibe nezici ezingajwayelekile, ngenxa yalokho kuzodinga ibhokisi elithile. I-subwoofer enjalo ivame ukutholakala ezinkampanini ezikhiqiza i-Kicker ne-DD. Kodwa-ke, abanye abakhiqizi nabo banezikhulumi ezinjalo, kodwa ngamanani amancane kakhulu.

Amavolumu ayalinganiselwa, ukusuka nokuya. Kuzohluka kuye ngokuthi isikhulumi, kodwa njengomthetho bazoba kupulaki efanayo ... Isibonelo, nge-subwoofer engu-12 intshi, lokhu kungamalitha angu-47-78 futhi ichweba lizosuka ku-140 kuya ku-270 square metres. bheka, nendlela yokubala ivolumu ngokuningiliziwe, sizofunda konke lokhu ezihlokweni ezilandelayo. Sithemba ukuthi lesi sihloko siphendule umbuzo wakho, uma uneminye imibono noma iziphakamiso, ungashiya amazwana akho ngezansi.

Ulwazi olufundile luphelele kulabo abafuna ukufunda ukubala amabhokisi bebodwa.

isiphetho

Senze umzamo omkhulu ekwakheni lesi sihloko, sizama ukusibhala ngolimi olulula noluqondakalayo. Kodwa kukuwe ukuthi sikwenzile noma cha. Uma usenemibuzo, dala isihloko "kuforamu", thina nomphakathi wethu onobungane sizoxoxa ngayo yonke imininingwane futhi sithole impendulo engcono kakhulu kuyo.
