Yadda za a haɗa tweeters tare da crossover zuwa amplifier?
Abubuwa
Fasaha ta yi nisa tun lokacin da aka shigar da tweeter na farko shekaru 15 da suka gabata, kuma mafi yawan masu tweeters na zamani yanzu suna zuwa tare da ginanniyar giciye. Amma zaka iya samun wasu ba tare da giciye ba. A cikin waɗannan lokuta, idan kun san mahimmancin crossover, kun san ba za ku taba shigar da tweeters ba tare da su ba. A yau zan mayar da hankali kan yadda ake haɗa tweeters crossover zuwa amplifier.
Gabaɗaya, don haɗa tweeter tare da ginanniyar giciye zuwa amplifier, bi waɗannan matakan.
- Da farko, haɗa madaidaicin waya na crossover zuwa madaidaicin tasha na amplifier.
- Sa'an nan kuma haɗa mummunan waya na crossover zuwa mummunan tashar amplifier.
- Sa'an nan haɗa sauran iyakar crossover zuwa tweeter (tabbatacce da korau).
- A ƙarshe, haɗa wasu direbobi kamar woofers ko subwoofers zuwa amplifier.
Shi ke nan. Yanzu tsarin sautin motar ku zai yi aiki daidai.
Mahimman ilimi game da tweeters da crossovers
Kafin mu fara tsarin haɗin gwiwa, yana da muhimmanci a sami wasu ilimi game da tweeters da crossovers.
Menene tweeter?
Don sake haifar da babban mitoci na 2000-20000 Hz, kuna buƙatar tweeter. Wadannan tweeters na iya canza makamashin lantarki zuwa raƙuman sauti. Don yin wannan, suna amfani da electromagnetism. Yawancin tweeters sun fi ƙanƙanta fiye da woofers, subwoofers da direbobi na tsakiya.
woofers: Woofers suna da ikon sake haifar da mitoci daga 40 Hz zuwa 3000 Hz.
Subwoofers: Yiwuwar haifuwa ta mitoci daga 20 Hz zuwa 120 Hz.
Direbobin Tsakanin Direba: Yiwuwar haifuwa ta mitoci daga 250 Hz zuwa 3000 Hz.
Kamar yadda kuke tsammani, tsarin sautin motar ku yana buƙatar aƙalla biyu ko fiye na direbobin da ke sama. In ba haka ba, ba zai iya kama wasu mitoci ba.
Menene crossover?
Ko da yake an ƙera direbobin lasifikar abubuwa don sake haifar da takamaiman mitoci, waɗannan direbobin ba za su iya tace mitoci ba. Don wannan kuna buƙatar crossover.
A wasu kalmomi, crossover yana taimaka wa tweeter kama mitoci tsakanin 2000-20000 Hz.
Yadda ake haɗa tweeters zuwa Ginshikan crossovers a cikin amplifier
Dangane da yanayin ku, ƙila kuna buƙatar ɗaukar hanyoyi daban-daban yayin haɗa tweeter ɗin ku. Misali, wasu tweeters suna da ginukan giciye a ciki wasu kuma ba sa. Don haka, a cikin hanyar 1, za mu tattauna ginanniyar giciye. Za mu mai da hankali kan ƙetare masu cin gashin kansu a cikin hanyoyin 2, 3 da 4.
Hanyar 1 - tweeter tare da ginannen giciye
Idan tweeter ya zo tare da ginanniyar giciye, ba za ku sami matsala ba ku shigar da tweeter da haɗa shi. Haɗa madaidaicin jagorar tweeter zuwa kyakkyawan ƙarshen amplifier. Sannan haɗa waya mara kyau zuwa ƙarshen mara kyau.
Ka tuna: A cikin wannan hanyar, crossover yana tace mitoci kawai don tweeter. Ba zai goyi bayan wasu direbobi kamar woofers ko subwoofers ba.
Hanyar 2 - Haɗa Tweeter Kai tsaye zuwa Amplifier tare da Crossover da Cikakken Kakakin Range
A cikin wannan hanyar, kuna buƙatar haɗa giciye kai tsaye zuwa amplifier. Sa'an nan kuma haɗa sauran iyakar crossover zuwa tweeter. Na gaba, muna haɗa duk sauran direbobi bisa ga zane na sama.
Wannan hanya tana da kyau don haɗa keɓaɓɓen ketare zuwa tweeter. Koyaya, crossover kawai yana goyan bayan tweeter.
Hanyar 3 - Haɗa tweeter tare da cikakken mai magana
Da farko, haɗa ingantacciyar waya na cikakken lasifikar kewayon zuwa ma'auni.
Sa'an nan kuma bi wannan tsari don waya mara kyau.
Sa'an nan kuma haɗa madaidaitan wayoyi masu kyau da marasa kyau na crossover zuwa mafi kyau da kuma mummunan ƙarshen mai magana.
A ƙarshe, haɗa tweeter zuwa crossover. Wannan babbar hanya ce don adana wasu waya mai magana.
Hanyar 4 - raba haɗin kai don tweeter da subwoofer
Idan amfani da subwoofer tare da tweeter, haɗa su daban zuwa amplifier. In ba haka ba, babban fitowar bass na iya lalata ko fashe tweeter.
Da farko, haɗa madaidaicin waya na crossover zuwa madaidaicin tasha na amplifier.
Sannan haɗa waya mara kyau zuwa ƙarshen mara kyau. Sa'an nan haɗa tweeter zuwa crossover. Tabbatar haɗa wayoyi bisa ga polarity.
Yanzu haɗa ingantattun wayoyi mara kyau da mara kyau na subwoofer zuwa wani tashar amplifier.
Wasu shawarwari waɗanda zasu iya taimakawa matakan da ke sama
Motoci na zamani suna da tashoshi 2 zuwa 4. Wadannan amplifiers na iya fitar da tweeter 4 ohm da cikakken kewayon 4 ohm (lokacin da aka haɗa su a layi daya).
Wasu amplifiers suna zuwa tare da ginanniyar giciye. Kuna iya amfani da waɗannan ginanniyar giciye ba tare da wata matsala ba. Koyaushe yi amfani da tweeter crossover. Hakanan, kar a taɓa haɗa tweeter da subwoofer.
Ga waɗanda ke neman haɓakawa, yana da kyau koyaushe a maye gurbin giciye na asali tare da giciye tare da lasifikan hanyoyi biyu.
Abin da za a kula da shi a lokacin wayoyi
Ba tare da ingantaccen wayoyi ba, ba za ku iya haɗa tweeters, crossovers, ko subwoofers da kyau ba. Don haka, bi waɗannan jagororin don samun sakamako mai kyau.
- Kada ku rikita polarities na wayoyi. A cikin misalan da ke sama, ƙila ku yi mu'amala da wayoyi 4 ko 6. Don haka, gano wayoyi daidai kuma ku haɗa wayoyi daidai. Layukan ja suna wakiltar wayoyi masu kyau kuma baƙar fata suna wakiltar wayoyi mara kyau.
- Yi amfani da masu haɗin haɗin gwiwa maimakon tef ɗin lantarki. Su ne mafi kyawun zaɓuɓɓuka don irin wannan tsarin wayoyi.
- Akwai masu girma dabam dabam dabam na masu haɗa crimp akan kasuwa. Don haka tabbatar da siyan wacce ta dace don wayoyin ku.
- Yi amfani da waya mai ma'auni 12 zuwa 18. Dangane da iko da nisa, ma'auni na iya bambanta.
- Yi amfani da kayan aiki kamar masu ɓarkewar waya da kayan aikin datsewa yayin aikin haɗin da ke sama. Samun irin waɗannan kayan aikin na iya yin babban bambanci. Misali, ƙwanƙolin waya shine zaɓi mafi kyau fiye da wuka mai amfani. (1)
Inda za a saka tweeters
Idan kana neman wurin hawan tweeter, gwada sanya shi a tsakiyar fasinja da kujerun direba.
Har ila yau, ƙofar mota ko ginshiƙan gefen kusa da gilashin gilashi kuma wurare ne masu kyau don hawan tweeter. Yawancin ma'aikata da aka shigar da tweeters ana shigar dasu a waɗannan wurare.
Koyaya, lokacin shigar da tweeters, tabbatar da zaɓar wurin da ya dace. Misali, wasu mutane ba sa son hawa tweeter a tsakiyar dashboard. Sautin da aka saba kusa da kunnuwa zai iya fusatar da su. Ƙofar mota ita ce wuri mafi dacewa don wannan yanayin. Har ila yau, lokacin da ka shigar da tweeter a kan ƙofar mota; Hakowa da shigarwa matakai ne quite sauki.
Zan iya amfani da tweeters akan subwoofer monoblock?
A monoblock sub amp yana da tashoshi ɗaya kawai kuma wannan tashar don haɓakar bass ne. Monoblock amplifiers ba su da babban mitoci. Don haka, ba za ku iya shigar da tweeter akan amplifier monoblock ba.
Koyaya, idan kuna amfani da amplifier na tashoshi da yawa tare da ƙarancin wucewa, bi matakan da ke ƙasa don ingantaccen aiki. (2)
- Lokacin amfani da amplifier na tashoshi da yawa, koyaushe haɗa tweeter zuwa tashar da ba a yi amfani da ita cikakke ba.
- Idan kana amfani da lasifika, haɗa tweeter a layi daya tare da masu magana.
- Koyaya, idan babu tashoshi marasa amfani a cikin amplifier, ba za ku iya haɗawa da twitter ba.
Tip: Matsakaicin ƙananan wucewa yana toshe mitoci mafi girma kuma suna ba da damar yin amfani da mitoci daga 50 Hz zuwa 250 Hz.
Don taƙaita
Ko kun sayi tweeter tare da ginanniyar giciye ko keɓancewar daban, kuna buƙatar haɗa tweeter da crossover zuwa amplifier. Hanya mafi kyau don yin wannan ita ce haɗa tweeter zuwa tashar da ba a amfani da ita.
A gefe guda, idan kuna amfani da subwoofer tare da tweeter, bi jagororin sama daidai.
Dubi wasu labaran mu a kasa.
- Yadda ake haɗa tweeters ba tare da giciye ba
- Yadda ake haɗa baturan sauti na mota da yawa
- Yadda za a bambanta waya mara kyau daga mai kyau
