Momwe mungasankhire bwino pogula subwoofer, pendani mawonekedwe ndi zina

Kukayendera sitolo yomvera zamagalimoto, mutha kugwa, kuchokera pamaso pa mitundu yosiyanasiyana ya subwoofers. Nkhaniyi iyankha funso la momwe mungasankhire subwoofer m'galimoto, ndi makhalidwe ati omwe muyenera kumvetsera komanso omwe ndi abwino kunyalanyaza, ganizirani mitundu ya mabokosi ndi phokoso lawo m'matupi osiyanasiyana a galimoto.

Pali zosankha zitatu za subwoofers:

1. Yogwira;
2. Kungokhala chete;
3. Chosankha pamene wokamba wosiyana agulidwa, bokosi limapangidwa pansi pake, amplifier ndi mawaya amagulidwa. Popeza kuti njirayi ikutanthauza njira yovuta komanso yokwera mtengo, pali nkhani ina, yolumikizana nayo, ndipo tinayika maganizo athu kumapeto kwa nkhaniyo. Koma choyamba, tikukulangizani kuti muwerenge nkhaniyi, momwemo tapenda zizindikiro zoyamba zomwe zingakhale zothandiza kwa inu posankha wokamba nkhani wa subwoofer, m'nkhani yotsatira sitidzabwereranso kwa iwo, koma tidzafufuza m'makhalidwe ovuta kwambiri.

Nkhaniyi ndiyabwino kwa okonda zomvera zamagalimoto oyambira omwe akufuna kuwonjezera mabasi kugalimoto yawo ndi ndalama zochepa.

Mitundu ya subwoofers, yogwira ntchito komanso yopanda pake

Monga tanenera kale, tikambirana njira ziwiri: imodzi ndi yosavuta, ina ndi yovuta kwambiri, koma yosangalatsa kwambiri.

Njira yoyamba ─ subwoofer yogwira. Chilichonse chikuphatikizidwa ndi izo, bokosi lomwe amplifier amawombera ndi mawaya onse ofunikira kuti agwirizane. Pambuyo pogula, zomwe zatsala ndikupita ku garaja kapena malo othandizira kuti muyike.

Njira yachiwiri ─ passive subwoofer. Apa chirichonse chiri chovuta pang'ono. Mumangotenga wokamba nkhani ndi bokosi. Wopangayo adawerengera, adasonkhanitsa bokosilo ndikusokoneza wokamba nkhaniyo. Mumasankha amplifier ndi mawaya nokha.

Poyerekeza, subwoofer yogwira ntchito ndi njira yowonjezera bajeti, ndipo zotsatira zake zidzakhala zoyenera, musayembekezere china chirichonse kuchokera kwa icho.

Passive subwoofer ─ sitepeyo yakwera kale.

Sitikhala pa gawoli kwa nthawi yayitali, kuti mumve zambiri, onani nkhaniyo poyerekeza ndi subwoofer yogwira komanso yogwira ntchito.

Ndizoyeneranso kudziwa kuti, muzochitika zamakono, sitimalimbikitsa passive subwoofers mu bokosi la fakitale. Tikukulangizani kuti muthe kulipira pang'ono ndikugula wokamba subwoofer ndi bokosi losiyana. Mtolowu udzakhala wokwera mtengo pang'ono, koma zotsatira zake zidzakudabwitseni.

Ndi makhalidwe ati omwe muyenera kusamala posankha subwoofer?

Kawirikawiri, opanga amayesa kusonyeza kuti mankhwala awo ndi abwino kuposa momwe alili. Akhoza kulemba manambala ena osatheka pabokosilo. Koma, poyang'ana malangizo, timapeza kuti palibe makhalidwe ambiri, monga lamulo, chifukwa palibe chapadera chodzitamandira. Komabe, ngakhale ndi mndandanda wawung'ono uwu, tidzatha kusankha bwino.

Kugwiritsa ntchito mphamvu

Tsopano, posankha subwoofer, zokonda zazikulu zimaperekedwa ku mphamvu, amakhulupirira kuti zida zamphamvu kwambiri, zimakhala bwino. Ndipotu izi sizowona. Tiyeni tiwone kuchuluka kwa mphamvu zomwe muyenera kulabadira.

Pamwamba (MAX)

Monga lamulo, wopanga amakonda kuwonetsa kulikonse, ndipo awa ndi manambala osadziwika. Mwachitsanzo, ma Watts 1000 kapena 2000, kuwonjezera apo, ndi ndalama zochepa. Koma kunena mofatsa, ichi ndi chinyengo. Mphamvu yamtunduwu siili pafupi. Mphamvu yapamwamba ndi mphamvu yomwe wokamba nkhani azisewera, koma kwakanthawi kochepa. Pankhaniyi, padzakhala kusokoneza koopsa kwa mawu. Tsoka ilo, munjira iyi, ntchito ya subwoofer sizomveka bwino ─ koma kungopulumuka masekondi angapo.

Adavoteledwa (RMS)

Mphamvu yotsatira yomwe tikambirana, ─ mphamvu mwadzina mu malangizo angatchulidwe kuti RMS. Izi ndi mphamvu zomwe kusokoneza kwa mawu kumakhala kochepa, ndipo wokamba nkhani amatha kusewera kwa nthawi yaitali popanda kudzivulaza, ndiye kuti muyenera kumvetsera. Ziribe kanthu momwe zingamvekere zachilendo, koma, mwachitsanzo, poyerekeza ndi subwoofer yamphamvu ndi yofooka, wofooka akhoza kusewera mokweza kuposa wamphamvu. Ndicho chifukwa chake mphamvu si chizindikiro chachikulu. Imaonetsa mphamvu imene wokamba nkhaniyo akugwiritsa ntchito, osati mokweza.

Ngati mugula passive subwoofer, voliyumu yake ndi kumveka kwake zimatengera mwachindunji ngati mwasankha amplifier yoyenera. Kuti mupewe vuto pamene subwoofer idagulidwa ndipo chifukwa cha amplifier yosayenera sichimasewera, tikukulangizani kuti muwerenge nkhani yakuti "Momwe mungasankhire amplifier kwa subwoofer"

Chisamaliro

Sensitivity ndi chiŵerengero cha dera la diffuser ndi sitiroko yake. Kuti wokambayo azisewera mokweza, amafunikira kondomu yayikulu komanso sitiroko yayikulu. Koma nthawi zambiri opanga amapanga kuyimitsidwa kwakukulu, milomo yochititsa chidwi. Anthu amaganiza kuti wokamba nkhaniyo ali ndi sitiroko yaikulu, ndipo amasewera mokweza, koma kwenikweni amataya oyankhula ndi kondomu yaikulu. Simuyenera kupereka zokonda kwa ma subwoofers okhala ndi milomo yayikulu, imataya yaying'ono, chifukwa wokamba nkhani wokhala ndi kondomu yayikulu amakhala ndi magwiridwe antchito apamwamba. Chifukwa chake, sitiroko yayikulu ndiyokongola, koma malo opangira ma diffuser ndiwothandiza kwambiri.

Chizindikirochi chimayesedwa motere. Amatenga cholankhulira, amayika maikolofoni pamtunda wa mita imodzi ndikuyika 1 watt mosamalitsa kwa wokamba nkhani. Maikolofoni imagwira zowerengera izi, mwachitsanzo, kwa subwoofer ikhoza kukhala 88 Db. Ngati mphamvu ikugwiritsidwa ntchito, ndiye kuti kukhudzidwa ndikubwereranso kwa subwoofer yokha. Powonjezera mphamvu ndi nthawi 2, kukhudzika kudzawonjezeka ndi 3 decibels, kusiyana kwa 3 decibels kumaonedwa kuti ndi 2-fold kuwonjezeka kwa voliyumu.

Tsopano mukumvetsa kuti mphamvu si chizindikiro chachikulu. Tiyeni titenge chitsanzo, subwoofer yoyamba ili ndi mphamvu yovotera ma Watts 300 ndi kukhudzika kwa ma decibel 85. Yachiwiri ilinso ndi ma watts 300 ndi kukhudzika kwa ma decibel 90. 260 watts anagwiritsidwa ntchito kwa wokamba nkhani woyamba, ndi 260 watts kwa wachiwiri, koma wokamba nkhani wachiwiri adzayimba dongosolo la magnitude mokweza chifukwa chogwira ntchito bwino.

Kukaniza (Impedance)

Kwenikweni, ma subwoofers onse amagalimoto amagalimoto amakhala ndi 4 ohms. Koma pali zosiyana, mwachitsanzo, 1 kapena 2 ohms. Kukaniza kumakhudza kuchuluka kwa mphamvu zomwe amplifier angapereke, kutsika kukana, mphamvu zambiri zomwe amplifier angapereke. Chilichonse chikuwoneka bwino, koma pamenepa chimayamba kusokoneza phokoso komanso kutentha kwambiri.

Tikukulimbikitsani kusankha kukana kwa 4 ohms ─ ichi ndi tanthauzo la golide pakati pa khalidwe ndi mokweza. Ngati subwoofer yogwira ili ndi kukana pang'ono kwa 1 kapena 2 ohms, ndiye kuti mwina wopanga akuyesera kufinya kuchuluka kwa amplifier, osalabadira kumveka bwino. Lamuloli silimagwira ntchito mokweza, komanso mumipikisano yothamanga. Ma subwoofers awa ali ndi ma coil awiri, chifukwa chake mutha kusintha kukana ndikusinthira kumunsi, zomwe zimakupatsani mwayi wopeza voliyumu yayikulu.

Kukula kwamphamvu

Chotsatira chomwe tingayang'ane tikabwera ku sitolo ndi kukula kwa subwoofer, oyankhula ambiri amakhala ndi mainchesi:

• 8 mainchesi (20cm)
• mainchesi 10 (25 cm);
• 12 mainchesi (30 cm);
• 15 mainchesi (38 cm);

Chofala kwambiri chimatengedwa kuti ndi mainchesi 12, titero kunena kwake, tanthauzo la golide. Ubwino wa wokamba waung'ono umaphatikizapo kuthamanga kwake kwa bass, ndi bokosi laling'ono lomwe lingathandize kusunga malo mu thunthu. Koma palinso zovuta ─ zimakhala zovuta kuti azisewera mabasi otsika. Ili ndi mphamvu zochepa, choncho imakhala chete. Gome ili m'munsili likuwonetsa momwe mawonekedwe amasinthira malinga ndi kukula kwake.

makhalidwe a	8 inchi (20cm)	10 inchi (25cm)	12 inchi (30cm)
Mphamvu ya RMS	80 W	101 W	121 watts
Kumverera (1W/1m)	87db ndi	88db ndi	90db ndi

Apa titha kumangirira pazokonda zanu zanyimbo. Tinene kuti mumakonda mitundu yosiyanasiyana ya nyimbo. Pankhaniyi, ndi bwino kuganizira 12 subwoofer. Ngati mulibe malo ambiri athunthu ndipo mumangomvera nyimbo zamakalabu, ndiye kuti kukula kwa 10-inch ndikoyenera kuganizira. Ngati mumakonda, mwachitsanzo, rap kapena nyimbo komwe kuli mabasi ambiri, ndipo thunthu limakupatsani mwayi, ndiye kuti ndi bwino kusankha subwoofer ya 15-inch ─ idzakhala ndi chidwi kwambiri.

Mtundu wa bokosi (mapangidwe omvera)

Chinthu chotsatira chomwe tingathe kuona momwe subwoofer idzasewere ndikuyang'ana mtundu wa bokosi ndikuwona zomwe zimapangidwira. Mabokosi odziwika kwambiri omwe mungapeze m'sitolo:

1. Bokosi lotsekedwa (ZYa);
2. kufufuza kwa danga (FI);
3. Bandpass (BP)

1. Taganizirani ubwino wa bokosi lotsekedwa. Ili ndi kukula kophatikizana kwambiri, mabasi othamanga komanso omveka bwino, kuchedwa kochepa kwamawu. Mwa minuses - kamangidwe kachetechete. Tsopano tikambirana za kukhazikitsa subwoofer m'matupi osiyanasiyana amagalimoto. Ngati ndinu mwini wa station wagon, hatchback, mukhoza kukhazikitsa 10, 12, 15 mainchesi popanda kusiyana. Ngati muli ndi sedan, ndiye kuti sikulimbikitsidwa kukhazikitsa 10-inch mu bokosi lotsekedwa, mudzangomva. Kuchita bwino kwa bokosilo ndikochepa kwambiri, 10 imasewera mwakachetechete, ndipo palibe chosangalatsa chomwe chidzabwere.
2. Njira yotsatira, yomwe nthawi zambiri imapezeka, ndi inverter ya gawo. Ili ndi bokosi lomwe lili ndi kagawo kapena dzenje. Imasewera mokweza maulendo 2 kuposa bokosi lotsekedwa ndipo ili ndi dongosolo la kukula kwake. Komabe, kwenikweni, khalidwe la mawu silimvekanso bwino, likumveka kwambiri. Komabe, iyi ndiye njira yabwino kwambiri ndipo ndi yoyenera kwa thupi lililonse lagalimoto. Chifukwa chake, inverter ya gawo ndi yokwezeka, kuchedwa kwake kuli mkati mwanthawi zonse, mtundu wa golide.
3. Bandpass ndi mapangidwe omwe wokamba nkhani amabisika m'bokosi. Nthawi zambiri amakongoletsedwa ndi plexiglass yokongola. Mu kukula, ndizofanana ndi gawo la inverter, koma panthawi imodzimodziyo ili ndi kubwerera kwakukulu. Ngati mukufuna kufinya kuchuluka kwa wokamba nkhani, ndiye kuti ndi bwino kugula bandpass. Komabe, ilinso ndi zovuta zake, mwachitsanzo, kapangidwe kake pang'onopang'ono. Ndizovuta kuti wolankhula uyu aziyimba nyimbo zamakalabu mwachangu, zikhala mochedwa.

Kwa iwo omwe akufuna kuzama mozama poyerekeza ndi mabokosi, omwe ndi kusamuka, malo adoko, ndi zizindikiro zina, werengani nkhaniyi momwe bokosilo limakhudzira phokoso.

Kumvetsera kwa subwoofer

Chotsatira choyenera kuchita posankha subwoofer ndikumvetsera. Gawoli silingatchulidwe kuti cholinga, chifukwa. phokoso m'chipinda ndi galimoto adzakhala osiyana. Pachifukwa ichi, si onse ogulitsa amafuna kugwirizanitsa ma subwoofers ndikuwonetsa momwe akusewera.

Cholinga chachikulu mu gawo ili ndi izi, mwasankha zingapo zimene mungachite malinga ndi makhalidwe. Ngati muwagwirizanitsa ndi kuwafanizira mulimonse, phokoso ndi voliyumu zidzakhala zosiyana kwa iwo, ndipo mudzapanga chisankho chomwe mumakonda.

Malangizo omvera:

1. Sikoyenera kufunsa mlangizi kuti agwirizane ndi subwoofer iliyonse. Sankhani njira ziwiri zofananira kutengera malingaliro omwe tapereka pamwambapa;
2. Yesani kufananiza pamitundu yosiyanasiyana, pomwe pali mabasi apamwamba komanso otsika, othamanga komanso odekha. Njira yabwino yofananizira ingakhale nyimbo zomwe mumamvetsera nthawi zambiri.
3. Sankhani mfundo imodzi yomvetsera, m'chipinda, phokoso m'madera osiyanasiyana a chipindacho lingakhale losiyana kwambiri.
4. Kumbukirani kuti subwoofer imakonda kusewera. Patapita kanthawi, voliyumu yake idzawonjezeka ndipo mabass adzamveka bwino komanso mofulumira.
5. Kodi simukumva kusiyana kwake? Pangani chisankho mokomera njira yotsika mtengo 🙂

Malamulowa amangogwira ntchito pamabokosi a subwoofers. Kuyerekeza okamba subwoofer sikumveka.

Kuphatikizidwa

Masiku ano, ma subwoofers a cabinet ataya mtengo wake. Pali zosankha zabwino pamsika. Ndi khama pang'ono ndi ndalama pang'ono, tidzapeza zotsatira 2 kapena 3 nthawi bwino. Ndipo njira iyi imatchedwa kugula subwoofer speaker. Inde, muyenera kuchitapo kanthu pang'ono, koma zotsatira zidzaposa zonse zomwe mukuyembekezera, tikukulangizani kuti muwerenge nkhani yakuti "Momwe mungasankhire wokamba subwoofer", zomwe zili mmenemo zidzakhalanso zothandiza kwa iwo amene akufuna kugula kabati subwoofer.

Kufika ku sitolo yoyamba, ndi chiyani chomwe chiyenera kutchera khutu, ndi subwoofer iti yomwe timasankha kungokhala kapena yogwira ntchito?

• Mu gawo ili, timalimbikitsa kupereka zokonda kwa subwoofer yogwira ntchito, chifukwa chake ndi motere. Subwoofer yopanda kanthu m'bokosi la fakitale ndi zowonjezera zonse zofunika mu mawonekedwe a amplifier ndi mawaya amatuluka osatsika mtengo. Powonjezera ndalama, tinene + 25%, titha kupita ku sitepe yotsatira. Gulani padera wokamba nkhani, bokosi loyenera la amplifier ndi mawaya, ndipo mtolo uwu udzasewera 100% yosangalatsa kwambiri.

Yachiwirizimene timatchera khutu

• chiŵerengero cha mphamvu zovotera (RMS) ndi kukhudzidwa. Timasankha mphamvu ndi chidwi malinga ndi mfundo yakuti "ndibwino kwambiri". Ngati subwoofer ili ndi mphamvu zambiri komanso mphamvu zochepa, ndiye kuti ndi bwino kusankha imodzi yokhala ndi chidziwitso chapamwamba, ngakhale itakhala yofooka pang'ono.

Chachitatu monga kukula kwa wokamba nkhani

• Ngati thunthu silikufunika kwenikweni, sankhani mainchesi okulirapo a subwoofer. Ngati mumamvera nyimbo zamakalabu, ndiye kuti ndibwino kusankha mainchesi 10 kapena 12.

Chachinayi za thupi

•  ngati kumveka bwino, kumveka bwino ndi tsatanetsatane ndizofunikira, - bokosi lotsekedwa, kuti muyike kumbuyo kwake kwakukulu - phokoso labata, timalimbikitsa kuyiyika m'magalimoto omwe thunthu ndi lofanana ndi chipinda chokwera, awa ndi magalimoto okhala ndi siteshoni. wagon hatchback ndi jeep.
• Nthawi zambiri, timalimbikitsa kapangidwe ka bokosilo - gawo la inverter. Izi ndiye tanthauzo la golide potengera kuchuluka, mtundu komanso liwiro la bass. Palibe chifukwa choti mukabwera ku sitolo, bokosi lamtunduwu lidzakhala lofala kwambiri.
• Ngati mukufuna voliyumu yayikulu pandalama zochepa, iyi ndi bandpass, ngakhale imagwiritsidwa ntchito kawirikawiri.

Chachisanu kumva ndi makutu

• Ndipo potsiriza, mvetserani zosankha zingapo za subwoofers m'chipindamo, chinthu ichi ndi chokayikitsa, koma mulimonsemo, pambuyo pake kukayikira konse kudzathetsedwa, ndipo mudzachotsa subwoofer yanu ndi malingaliro omwe mwasankha bwino.
