Saita subwoofer a cikin mota

Subwoofer yana da kyau ƙari ga tsarin sauti na motar. Amma yana da daraja la'akari da cewa sayen subwoofer mai tsada ba ya tabbatar da ingancin sauti mai kyau, saboda wannan na'urar yana buƙatar daidaitawa sosai.

Tabbas, kafin kafa subwoofer a cikin mota, yana da kyau a nemi taimako daga kwararru, kuma ga masu motoci da suke so su yi da kansu, wannan labarin zai zama da amfani.

A ina za a fara kafa subwoofer?

Subwoofer tuning yana farawa daga lokacin da aka yi akwatin. Ta hanyar canza halaye na akwatin (ƙarar, tsawon tashar tashar jiragen ruwa), za ku iya cimma sautuna daban-daban. A wannan yanayin, kuna buƙatar sanin a gaba waɗanda fayilolin mai jiwuwa za a fi kunna su a cikin motar, da kuma abin da za a haɗa amplifier zuwa tsarin sauti.

Ɗaya daga cikin muhimman abubuwan da ke shafar ingancin sauti shine amplifier, muna ba ku shawara ku karanta labarin "Yadda za a zabi amplifier".

Saitin tacewa LPF (lowpassfilter).

Da farko kuna buƙatar saita matattara mai ƙarancin wucewa (LPF). Kowane subwoofer a yau yana da ginanniyar tacewa ta LPF. Tace tana ba ku damar zaɓar ƙofa wanda zai fara toshe manyan mitoci, yana ba da damar siginar subwoofer don haɗawa ta halitta tare da sauran masu magana.

Shigar da tacewa, kamar kafa subwoofer mai aiki, ya ƙunshi gwaji da yawa - kawai babu takamaiman “tsari” daidai.

An tsara subwoofer don sake haifar da ƙananan ƙananan ƙananan ƙananan, ba zai iya raira waƙa ba, wannan shine aikin masu magana. Godiya ga ƙarancin mitar LPF, za mu iya sa subwoofer ya kunna bass current. Kuna buƙatar tabbatar da cewa ba a saita ƙimar tacewa da yawa ba kuma subwoofer ba ya mamaye woofers na masu magana da cikakken kewayon ku. Wannan na iya haifar da wuce gona da iri akan kewayon mitar guda ɗaya (ce, a kusa da 120 Hz) da tsarin lasifikar da ba ta da kyau. A gefe guda, idan ka saita tace tayi ƙasa sosai, za a iya samun bambanci da yawa tsakanin siginar subwoofer da siginar lasifikar.

Kewayon subwoofer yawanci shine 60 zuwa 120. Gwada saita tacewa LPF a 80 Hz da farko, sannan gwada sautin. Idan ba ku son shi, daidaita canjin har sai lasifikan sun yi sauti yadda kuke so.

Saitin Subsonic

Bayan haka, kuna buƙatar kunna tace infrasonic, wanda ake kira "subonic". Subsonic yana toshe ƙananan ƙananan mitoci waɗanda a zahiri ke faruwa a wasu waƙoƙin. Ba za ku iya jin waɗannan mitoci ba saboda sun wanzu ƙasa da bakin kofa na jin ɗan adam.

Amma idan ba a yanke su ba, subwoofer zai yi amfani da ƙarin ƙarfi don kunna su.

Haka kuma, a cikin wannan yanayin, an cire gazawar coil subwoofer saboda haɓakar motsi na mazugi.

Menene Bassboost don?

Yawancin amplifiers kuma sun haɗa da maɓallin Bassboost wanda zai iya ƙara ƙarfin subwoofer ta hanyar saita shi zuwa takamaiman mita. Wasu masu ababen hawa suna amfani da maɓalli don ƙara sautin “arziƙi”, kodayake galibi ana amfani da shi don rarraba bass daidai gwargwado. Idan kun saita sauyawa zuwa matsakaicin ƙimar, to subwoofer na iya ƙonewa, duk da haka, kashe Bassboost gabaɗaya shima bai cancanci hakan ba, saboda a cikin wannan yanayin bass ba zai iya jin komai ba.

Daidaita Mahimmancin Input (GAIN)

Wasu masu ababen hawa ba su fahimci yadda ake saita hankalin shigarwar yadda ya kamata ba. Hankalin shigar da bayanai yana nuna adadin sigina da za a iya amfani da shi ga abin shigarwa don samun ƙimar fitarwar da aka ƙididdigewa. Dole ne a daidaita shi don daidaita ƙarfin siginar shigarwa.

Yana da matukar mahimmanci a saita yanayin shigar da bayanai daidai, saboda wannan zai taimaka don guje wa karkatar da sigina, rashin ingancin sauti, ko lalata masu magana.

Don daidaita "GAIN", kuna buƙatar

3. umarnin don subwoofer, wanda ke nuna ƙarfin fitarwa da aka halatta.

Da farko kuna buƙatar cire haɗin wayoyi masu magana daga subwoofer. Bayan haka, kuna buƙatar tabbatar da cewa an kashe bass, masu daidaitawa da sauran sigogi a kan naúrar kai don samun sauti mai haske. A wannan yanayin, matakin shigar da hankali ya kamata ya zama ƙasa kaɗan gwargwadon yiwuwa.

Tabbatar cewa voltmeter na dijital zai iya karanta wutar lantarki ta AC kuma ya haɗa shi zuwa tashoshin lasifikan da ke kan lasifikar ku (zaku iya amintar da shi da sukudireba). Bayan haka, dole ne ku kunna hankali "karkacewa" har sai voltmeter ya nuna ƙimar ƙarfin lantarki da ake buƙata, wanda aka nuna a cikin ƙayyadaddun bayanai.

Na gaba, fayilolin mai jiwuwa da aka yi rikodin tare da sinusoid dole ne a ciyar da su zuwa subwoofer lokaci zuwa lokaci ta hanyar canza ƙarar tsarin sauti har sai tsangwama ya faru. A cikin yanayin tsangwama, dole ne a mayar da ƙarar zuwa ƙimar da ta gabata. Haka yake don daidaita hankali. Ana iya amfani da oscilloscope don samun ingantaccen bayanai.

Lokaci na Acoustic

Yawancin subwoofers suna da canji a baya da ake kira "Phase" wanda za'a iya saita shi zuwa digiri 0 ko 180. Daga mahangar lantarki, wannan shine abu na biyu mafi sauƙi da za a yi bayan kunnawa/kashewa.

Idan kun saita wutar lantarki zuwa gefe ɗaya, to, masu gudanarwa guda biyu zasu ɗauki siginar daga fitarwa zuwa sauran na'urorin lantarki a hanya ɗaya.

Manufar saitin jinkiri shine cimma nasarar sake kunnawa lokaci guda na subwoofer da masu magana da gaba (bai kamata a bar sautin ya tsaya ba ko da na dakika biyu).

Me yasa yake da mahimmanci don dock subwoofers da midbass daidai?

Idan subwoofer ba shi da kyau tare da midbass, to sautin zai zama mara kyau kuma mara kyau. Ana iya lura da wannan musamman a ƙananan mitoci, lokacin da aka sami wani nau'in shirme maimakon bass mai tsabta.
