Kodi bokosi la subwoofer limakhudza bwanji phokoso?

Muzomvera zamagalimoto, pali zosankha zambiri zamabokosi opangira ma acoustic. Choncho, ambiri oyamba kumene sadziwa zomwe zili bwino kusankha. Mitundu yotchuka kwambiri yamabokosi a subwoofer ndi bokosi lotsekedwa ndi inverter ya gawo.

Ndipo palinso mapangidwe monga bandpass, quarter-wave resonator, free air ndi ena, koma pomanga machitidwe amagwiritsidwa ntchito kawirikawiri pazifukwa zosiyanasiyana. Zili kwa mwiniwake wa wokamba nkhani kuti asankhe bokosi la subwoofer lomwe lingasankhe malinga ndi zofunikira zomveka komanso chidziwitso.

Tikukulangizani kuti mumvetsere nkhani yomwe ili bwino kupanga bokosi la subwoofer. Tawonetsa momveka bwino momwe kulimba kwa bokosi kumakhudzira ubwino ndi kuchuluka kwa bass.

bokosi lotsekedwa

Mapangidwe amtunduwu ndi osavuta. Bokosi lotsekedwa la subwoofer ndilosavuta kuwerengera ndi kusonkhanitsa. Mapangidwe ake ndi bokosi la makoma angapo, nthawi zambiri a 6.

Ubwino wa ZY:

1. Kuwerengera kosavuta;
2. Kusonkhana kosavuta;
3. Kusamuka kwakung'ono kwa bokosi lomalizidwa, chifukwa chake compactness;
4. Makhalidwe abwino opupuluma;
5. Mabasi othamanga komanso omveka bwino. Amasewera ma track a club bwino.

Kuipa kwa bokosi lotsekedwa ndi chimodzi chokha, koma nthawi zina chimakhala chokhazikika. Mapangidwe amtunduwu ali ndi gawo lochepa kwambiri la magwiridwe antchito poyerekeza ndi mabokosi ena. Bokosi lotsekedwa siloyenera kwa iwo omwe akufuna kuthamanga kwapamwamba.

Komabe, ndi yoyenera kwa mafani a rock, club music, jazz ndi zina zotero. Ngati munthu akufuna mabass, koma amafunikira malo mu thunthu, ndiye kuti bokosi lotsekedwa ndiloyenera. Bokosi lotsekedwa lidzasewera bwino ngati voliyumu yolakwika yasankhidwa. Ndi voliyumu yanji ya bokosi yomwe ikufunika pakupanga kwamtunduwu idasankhidwa kale ndi anthu odziwa bwino pamawu agalimoto kudzera kuwerengera ndi kuyesa. Kusankhidwa kwa voliyumu kumatengera kukula kwa subwoofer.

Nthawi zambiri pali okamba kukula uku: 6, 8, 10, 12, 15, 18 mainchesi. Koma mutha kupezanso olankhula amitundu ina, monga lamulo, amagwiritsidwa ntchito kawirikawiri pakuyika. Ma Subwoofers okhala ndi mainchesi 6 amapangidwa ndi makampani angapo komanso osowa pakuyika. Anthu ambiri amasankha oyankhula okhala ndi mainchesi 8-18. Anthu ena amapereka mainchesi a subwoofer mu masentimita, zomwe sizolondola kwenikweni. Muzomvera zamagalimoto zamagalimoto, ndi chizolowezi kufotokoza makulidwe a mainchesi.

Voliyumu yovomerezeka ya subwoofer yotsekedwa bokosi:

• 8-inch subwoofer (20 cm) imafuna malita 8-12 a voliyumu ya ukonde,
• kwa 10-inch (25 cm) 13-23 malita a voliyumu ya ukonde,
• kwa 12-inch (30 cm) 24-37 malita a voliyumu ya ukonde,
• kwa 15" (38 cm) 38-57-lita voliyumu
• ndi imodzi ya mainchesi 18 (46 cm) mudzafunika malita 58-80.

Voliyumu imaperekedwa pafupifupi, popeza kwa wokamba aliyense muyenera kusankha voliyumu inayake potengera mawonekedwe ake. Kuyika kwa bokosi lotsekedwa kudzadalira kuchuluka kwake. Kukula kwa bokosilo, kutsika kwafupipafupi kwa bokosilo, mabass adzakhala ofewa. Zing'onozing'ono voliyumu ya bokosi, kukwera kwafupipafupi kwa bokosilo, mabasi adzakhala omveka komanso mofulumira. Osachulukitsa kapena kuchepetsa mawu kwambiri, chifukwa izi zimakhala ndi zotsatirapo zake. Powerengera bokosilo, tsatirani voliyumu yomwe idakhazikitsidwa pamwambapa.Ngati pali kufufuza kwa voliyumu, ndiye kuti bass imakhala yosamveka bwino, yosamveka bwino. Ngati voliyumu sikokwanira, ndiye kuti mabasi adzakhala othamanga kwambiri komanso "nyundo" m'makutu molakwika kwambiri.

Zambiri zimatengera makonda abokosi, koma mfundo yofunika kwambiri ndi "Kukhazikitsa Wailesi".

Space inverter

Mapangidwe amtunduwu ndi ovuta kuwerengera ndi kumanga. Mapangidwe ake ndi osiyana kwambiri ndi bokosi lotsekedwa. Komabe, ili ndi zabwino zake, zomwe ndi:

1. Mkulu mlingo wa dzuwa. Inverter ya gawo idzatulutsanso ma frequency otsika kwambiri kuposa bokosi lotsekedwa;
2. Kuwerengera kosavuta kwa hull;
3. Kukonzanso ngati kuli kofunikira. Izi ndizofunikira makamaka kwa oyamba kumene;
4. Kuziziritsa kwa speaker kwabwino.

Komanso, inverter ya gawo ilinso ndi zovuta, kuchuluka kwake komwe kuli kwakukulu kuposa kwa WL. Choncho kuipa:

• PHI ndi yomveka kuposa WL, koma mabass apa salinso omveka komanso othamanga;
• Miyeso ya bokosi la FI ndi yaikulu kwambiri poyerekeza ndi ZYa;
• Kukhoza kwakukulu. Pachifukwa ichi, bokosi lomalizidwa lidzatenga malo ambiri mu thunthu.

Kutengera zabwino ndi zoyipa zake, mutha kumvetsetsa komwe mabokosi a PHI amagwiritsidwa ntchito. Nthawi zambiri amagwiritsidwa ntchito pakuyika komwe ma bass okweza komanso otchulira amafunikira. Inverter ya gawo ndi yoyenera kwa omvera a nyimbo za rap, zamagetsi ndi kalabu. Komanso ndi yoyenera kwa iwo omwe safuna malo aulere mu thunthu, chifukwa bokosilo litenga pafupifupi danga lonselo.

Bokosi la FI likuthandizani kuti mupeze mabass ochulukirapo kuposa mu WL kuchokera ku speaker yaing'ono. Komabe, izi zidzafuna malo ochulukirapo.

Ndi voliyumu yanji ya bokosi yomwe imafunikira pagawo la inverter?

• pa subwoofer yokhala ndi mainchesi 8 (20 cm), mudzafunika malita 20-33 a voliyumu;
• kwa wokamba 10-inch (25 cm) - 34-46 malita,
• kwa 12-inch (30 cm) - 47-78 malita,
• kwa 15-inch (38 cm) - 79-120 malita
• ndi 18-inch subwoofer (46 cm) muyenera 120-170 malita.

Monga momwe zilili ndi ZYa, manambala olakwika amaperekedwa apa. Komabe, mu nkhani ya FI, mukhoza "kusewera" ndi voliyumu ndikutenga mtengo wocheperapo kusiyana ndi zomwe zikulimbikitsidwa, kupeza kuti ndi voliyumu yanji yomwe subwoofer imasewera bwino. Koma musaonjezere kapena kuchepetsa mawu kwambiri, izi zingayambitse kutaya mphamvu ndi kulephera kwa wokamba nkhani. Ndi bwino kudalira malingaliro a wopanga subwoofer.

Zomwe zimatsimikizira kukhazikitsidwa kwa bokosi la FI

Kuchuluka kwa bokosilo, kutsika kwafupipafupi kudzakhala, kuthamanga kwa bass kudzachepa. Ngati mukufuna ma frequency apamwamba, ndiye kuti voliyumu iyenera kuchepetsedwa. Ngati mphamvu yanu ya amplifier iposa mphamvu ya oyankhula, ndiye kuti tikulimbikitsidwa kuti voliyumu ikhale yaying'ono. Izi ndizofunikira kuti mugawire katundu pa wokamba nkhani ndikuletsa kupitirira sitiroko. Ngati amplifier ndi yofooka kuposa wokamba nkhani, ndiye kuti timalimbikitsa kuti voliyumu ya bokosi ikhale yokulirapo. Izi zimalipira voliyumu chifukwa chosowa mphamvu.

Dera la doko liyeneranso kudalira kuchuluka kwake. Makhalidwe apakati pa doko la speaker ndi motere:

kwa subwoofer ya 8-inch, 60-115 sq. cm idzafunika,

kwa 10-inch - 100-160 sq. cm,

kwa 12-inch - 140-270 sq. cm,

kwa 15-inch - 240-420 sq. cm,

kwa 18-inch - 360-580 sq.

Kutalika kwa doko kumakhudzanso kusinthasintha kwa bokosi la subwoofer, kutalika kwa doko, kutsika kwa bokosi, kufupi ndi doko, motsatira, mafupipafupi akukonzekera ndi apamwamba. Powerengera bokosi la subwoofer, choyamba, muyenera kudzidziwa bwino ndi mikhalidwe ya wokamba nkhani ndi magawo omwe akulimbikitsidwa. Nthawi zina, wopanga amalimbikitsa magawo osiyanasiyana a bokosi kuposa omwe aperekedwa m'nkhaniyi. Wokamba nkhaniyo akhoza kukhala ndi makhalidwe omwe si oyenera, chifukwa chake adzafunika bokosi linalake. Subwoofer yotereyi imapezeka nthawi zambiri m'makampani opanga Kicker ndi DD. Komabe, opanga ena amakhalanso ndi oyankhula oterowo, koma mochepa kwambiri.

Ma voliyumu ndi pafupifupi, kuchokera ndi kupita. Zidzasiyana malinga ndi wokamba nkhani, koma monga lamulo iwo adzakhala mu pulagi yomweyo ... Mwachitsanzo, kwa 12 inchi subwoofer, iyi ndi malita 47-78 ndipo doko lidzakhala kuchokera 140 mpaka 270 lalikulu mamita. onani, ndi momwe mungawerengere voliyumu mwatsatanetsatane, tiphunzira zonsezi m'nkhani zotsatila. Tikukhulupirira kuti nkhaniyi yayankha funso lanu, ngati muli ndi ndemanga kapena malingaliro, mutha kusiya ndemanga yanu pansipa.

Zomwe mwaphunzira ndizabwino kwa iwo omwe akufuna kuphunzira kuwerengera mabokosi pawokha.

Pomaliza

Tachita khama kwambiri popanga nkhaniyi, kuyesera kuilemba m'chinenero chosavuta komanso chomveka. Koma zili ndi inu kusankha ngati tinachita kapena ayi. Ngati mudakali ndi mafunso, pangani mutu pa "Forum", ife ndi gulu lathu laubwenzi tidzakambirana mwatsatanetsatane ndikupeza yankho labwino kwambiri.
