Kupanga subwoofer m'galimoto

Subwoofer ndiyowonjezera bwino pamawu omveka agalimoto. Koma ndi bwino kuganizira kuti kugula subwoofer yamtengo wapatali sikutsimikizira phokoso lapamwamba, chifukwa chipangizochi chiyenera kukonzedwa bwino. Kuti mugwirizane ndi kukhazikitsa subwoofer moyenera, simuyenera kukhala ndi kumva bwino, komanso chidziwitso chozama cha chiphunzitso cha audio audio.

Inde, musanakhazikitse subwoofer m'galimoto, ndi bwino kufunafuna thandizo kwa akatswiri, ndipo kwa oyendetsa galimoto omwe akufuna kuchita okha, nkhaniyi idzakhala yothandiza.

Momwe mungayambire kukhazikitsa subwoofer?

Kukonzekera kwa subwoofer kumayambira pomwe bokosilo limapangidwa. Posintha mawonekedwe a bokosi (voliyumu, kutalika kwa doko), mutha kukwaniritsa mawu osiyanasiyana. Pankhaniyi, muyenera kudziwiratu kuti mafayilo amawu azisewera m'galimoto, komanso amplifier ati omwe adzalumikizidwa ndi pulogalamu yomvera. Pamene subwoofer yaperekedwa kale pankhani ya wopanga, ndiye kuti kusinthasintha kwa kukhazikitsa kumakhala kocheperako, ngakhale ndi chidziwitso chofunikira ndizotheka kukwaniritsa mawu omwe mukufuna.

Chimodzi mwazinthu zofunika zomwe zimakhudza kumveka kwa mawu ndi amplifier, tikukulangizani kuti muwerenge nkhani yakuti "Momwe mungasankhire amplifier".

Zosefera za LPF (lowpassfilter).

Choyamba muyenera kukhazikitsa zosefera zotsika (LPF). Subwoofer iliyonse lero ili ndi fyuluta ya LPF yomangidwa. Fyuluta imakulolani kuti musankhe poyambira pomwe imayamba kutsekereza ma frequency apamwamba, kulola kuti chizindikiro cha subwoofer chigwirizane mwachilengedwe ndi olankhula ena.

Kuyika fyuluta, monga kukhazikitsa subwoofer yogwira, imakhala ndi zoyeserera zambiri - palibe "chilinganizo" cholondola.

Subwoofer idapangidwa kuti ibereke ma frequency otsika, sangathe kuyimba, iyi ndi ntchito ya okamba. Chifukwa cha fyuluta yotsika ya LPF, titha kupanga subwoofer kusewera bass pakali pano. Muyenera kuwonetsetsa kuti mtengo wa fyuluta sunakhazikitsidwe kwambiri komanso kuti subwoofer sichidutsana ndi woofers oyankhula anu athunthu. Izi zitha kupangitsa kutsindika kopitilira muyeso umodzi wa ma frequency (nenani, mozungulira 120 Hz) ndi makina olankhula osamveka bwino. Kumbali ina, ngati muyika fyuluta yotsika kwambiri, pangakhale kusiyana kwakukulu pakati pa chizindikiro cha subwoofer ndi siginecha yolankhula.

Mitundu ya subwoofer nthawi zambiri imakhala 60 mpaka 120. Yesani kukhazikitsa fyuluta ya LPF pa 80 Hz poyamba, ndiyeno yesani phokoso. Ngati simukuzikonda, sinthani masinthidwe mpaka okamba amveke momwe mukufunira.

Pawailesi yokha, fyuluta iyenera kuzimitsidwa.

Kupanga kwa Subsonic

Kenako, muyenera yambitsa infrasonic fyuluta, wotchedwa "subsonic". Ma subsonic amaletsa ma frequency otsika kwambiri omwe amapezeka mwachilengedwe mu nyimbo zina. Simungamve ma frequency awa chifukwa amakhala pansi pa makutu a anthu.

Koma ngati sanadulidwe, subwoofer idzagwiritsa ntchito mphamvu zowonjezera kuti izisewera. Poletsa ma infra-low ma frequency, chipangizochi chizitha kutulutsanso bwino ma frequency omwe ali mkati mwazomveka. Komanso, pamenepa, kulephera kwa koyilo ya subwoofer chifukwa cha kusuntha kwachangu kwa cone sikuphatikizidwa.

Kodi Bassboost ndi chiyani?

Ma amplifiers ambiri amaphatikizanso kusintha kwa Bassboost komwe kumatha kuwonjezera mphamvu ya subwoofer poyiyika pafupipafupi. Oyendetsa galimoto ena amagwiritsa ntchito kusinthana kuti phokoso likhale "lolemera", ngakhale kuti nthawi zambiri amagwiritsidwa ntchito kugawa mofanana mabasi. Ngati muyika kusintha kwamtengo wapatali, ndiye kuti subwoofer ikhoza kutenthedwa, komabe, kuzimitsa Bassboost kwathunthu sikuli koyenera, chifukwa pamenepa, mabasi sangamve konse.

Kusintha Kumverera kwa Input (GAIN)

Madalaivala ena samamvetsetsa momwe angakhazikitsire kukhudzidwa kolowera. Kuzindikira kolowetsa kumawonetsa kuchuluka kwa siginecha yomwe ingagwiritsidwe ntchito pazolowetsamo kuti mupeze mphamvu yotulutsa. Iyenera kusinthidwa kuti isinthe mphamvu yamagetsi yolowera.

Ndikofunikira kwambiri kuyika kukhudzidwa kolowera moyenera, chifukwa izi zithandizira kupewa kupotoza kwa ma siginecha, kusamveka bwino kwa mawu, kapena kuwonongeka kwa okamba.

Kuti musinthe "PAIN", muyenera

1. voltmeter ya digito yomwe imatha kuyeza mayendedwe amagetsi a AC;
2. CD yoyesera kapena fayilo yokhala ndi 0 dB sine wave (yofunikira kwambiri kuti musagwiritse ntchito chizindikiro choyeserera);
3. malangizo a subwoofer, omwe akuwonetsa voteji yovomerezeka.

Choyamba muyenera kuchotsa mawaya oyankhula kuchokera ku subwoofer. Kenako, muyenera kuonetsetsa kuti mabasi, ofananira ndi magawo ena azimitsidwa pamutu kuti amveke bwino. Pachifukwa ichi, mlingo wa sensitivity wolowetsa uyenera kukhala wotsika momwe ungathere.

Onetsetsani kuti voltmeter ya digito imatha kuwerenga voteji ya AC ndikuyilumikiza ku ma terminals a speaker pama speaker anu (mutha kuyiteteza ndi screwdriver). Pambuyo pake, muyenera kutembenuza mphamvuyo "kupotoza" mpaka voltmeter ikuwonetsa mtengo wofunikira wa voteji, womwe ukuwonetsedwa muzofotokozera.

Kenaka, fayilo yojambulidwa yojambulidwa ndi sinusoid iyenera kudyetsedwa kwa subwoofer nthawi ndi nthawi mwa kusintha voliyumu ya audio system mpaka kusokonezedwa. Pakachitika zosokoneza, voliyumu iyenera kubwezeretsedwanso ku mtengo wake wakale. Zomwezo zimapitanso pakusintha kukhudzidwa. An oscilloscope angagwiritsidwe ntchito kupeza deta yolondola kwambiri.

Acoustic gawo

Ma subwoofers ambiri amakhala ndi chosinthira kumbuyo chotchedwa "Phase" chomwe chimatha kukhazikitsidwa ku 0 kapena 180 madigiri. Kuchokera kumagetsi, ichi ndi chinthu chachiwiri chophweka kuchita pambuyo pa kuyatsa / kuzimitsa.

Ngati muyika chosinthira mphamvu kumbali imodzi, ndiye kuti ma conductor awiri amanyamula chizindikirocho kuchokera pazotulutsa kupita kuzinthu zina zonse zamagetsi mbali imodzi. Ndikokwanira kutembenuza chosinthira ndipo ma conductor awiri amasintha malo. Izi zikutanthauza kuti mawonekedwe a phokoso adzasinthidwa (zomwe ndi zomwe akatswiri amatanthauza akamalankhula za kutembenuza gawolo, kapena kusintha madigiri a 180).

Koma kodi womvera nthawi zonse amapeza chiyani chifukwa cha kusintha kwa magawo?

Chowonadi ndi chakuti mothandizidwa ndi kusinthana ndi gawo losinthira, mutha kukwaniritsa malingaliro apamwamba kwambiri apakati ndi apamwamba akumvetsera. Ndikuthokoza kwa gawo losinthira kuti mutha kukwaniritsa mabass onse omwe mudalipira.

Kuphatikiza apo, kusintha kwa gawo la monoblock kumathandizira kukwaniritsa ndendende phokoso lakutsogolo. Nthawi zambiri zimachitika kuti phokoso limagawidwa mosagwirizana m'nyumba yonse (nyimbo zimangomveka kuchokera ku thunthu).

Kuchedwa

Ma Subwoofers amakonda kuchedwa pang'ono, ndipo amafanana mwachindunji ndi kukula kwa mtunda. Mwachitsanzo, olankhula ochokera ku America wopanga Audissey adakhazikitsa dala mtunda wautali kuti aletse kuchedwa uku.

Ndikoyenera kudziwa kuti kukonza pamanja kwa amplifier kwa subwoofer kumatheka pokhapokha ngati pali purosesa yakunja kapena purosesa yophatikizika. Chizindikiro chakuti subwoofer imayambitsa kuchedwa ikhoza kuonedwa ngati mochedwa, zomwe nthawi zina zimawononga phokoso. Cholinga cha kuchedwetsako ndikukwaniritsa kuseweredwa munthawi yomweyo kwa subwoofer ndi oyankhula akutsogolo (phokoso siliyenera kuloledwa kuchedwa ngakhale kwa masekondi angapo).

Chifukwa chiyani kuli kofunikira kuyika ma subwoofers ndi midbass molondola?

Ngati subwoofer ilibe bwino ndi midbass, ndiye kuti phokoso lidzakhala lopanda khalidwe komanso lotsika. Izi zimawonekera makamaka pama frequency otsika, pomwe mtundu wina wachabechabe umapezeka m'malo mwa mabass oyera. Nthawi zina zosankha zoyipa zotere zimatheka, pomwe phokoso lochokera ku subwoofer nthawi zambiri limasewera palokha.

M'malo mwake, izi zimagwira ntchito ku mitundu yonse ya nyimbo, osati kungonena, nyimbo zachikale kapena za rock, pomwe kusewera kwa zida zoimbira "zamoyo" kumawonedwa.

Mwachitsanzo, m'mayendedwe omwe ali amtundu wa EDM, omwe amadziwika kwambiri pakati pa achinyamata, mabasi owala kwambiri amakhala ndendende pamphambano ndi midbass. Ngati muwakhomerera molakwika, ndiye kuti ma bass otsika kwambiri sangakhale osangalatsa kwambiri, ndipo choyipa kwambiri sichidzamveka bwino.

Popeza ndikofunikira kusinthira amplifier pafupipafupi, tikulimbikitsidwa kugwiritsa ntchito chowunikira cha audio spectrum kuti mupeze zolondola kwambiri.

Kodi mungamvetse bwanji kuti mwakhazikitsa subwoofer molondola?

Ngati subwoofer ikugwirizana bwino, ndiye kuti anthu omwe ali m'galimoto sangathe kumva, chifukwa sayenera kusokoneza chizindikiro chachikulu.

Ngati mumamvetsera nyimbo ndi voliyumu yotsika, zingawoneke kuti palibe mabasi okwanira. Kuperewera kwa mabass pama voliyumu otsika ndi chizindikiro chotsimikizika kuti subwoofer yalumikizidwa molondola.

Zoonadi, sipayenera kukhala phokoso, kusokoneza kapena kuchedwa mu siginecha ya audio, ndipo ziribe kanthu kuti ndi mtundu wanji wa mapangidwe omwe amagwiritsidwa ntchito.

Kuchuluka kwa bass mu nyimbo iliyonse kuyenera kukhala kosiyana, ndiko kuti, kusewera kuyenera kufanana kwathunthu ndi nyimbo yoyambirira yojambulidwa ndi wopanga.

Nkhani yotsatira yomwe timalimbikitsa kuwerenga imatchedwa "Momwe Bokosi la Subwoofer Limakhudzira Phokoso".
