Umhlathi S90: iinkcukacha, scheme. Izithethi ngezandla zabo

Audiophiles nokuphakanyiswa isityalo ongatshiyo ngento isithethi ekhethiweyo ukuba ukuphulaphula bekhululekile umculo ekhaya. Kwaye ngenxa yesizathu olungileyo; anokuvela yonke yahlulwa ndimfuduka mbini. I yangaphambili bakholelwa ukuba kuyimfuneko ukuba babeke isixa icocekile ukuba kuthengwe emaweni Hi-Fi (okanye Hi-End nokuba ngcono) inkqubo, ku tsakela bakulibale yintloko malunga nesi sihloko yobomi. Kodwa kukho abo abavumi ukuba bayeke nokwanda ubomi bakhe ngenxa izithethi eninzi (endaweni imoto okanye indlu), yaye ngenxa yoko igqalwa lowo ilungileyo ukuze kuthengwe izixhobo ezilula okanye ekugqityweni sakudala elungileyo endala isandi elungileyo.

Eli nqaku sigxile enye kwiindlela ezininzi ethandwa audio nangoku ukuvelisa amaxesha waseUSSR, ngubani akayi kungamohlwayi nabani na xa ebona yomnini. Izithethi S90, iimpawu zobugcisa ezinako ukubangela ingqondo ndikubhadulise nanamhla, iye yaba enye yempumelelo aphezulu bumabumela eSoviet "Radio".

models isithethi

Into yokuqala ekubalulekileyo ukuzikhankanya yi langoku igama elipheleleyo yemifanekiso isithethi - 35AS-012. Enye into ebalulekileyo kukuba isithethi ifumaneka kwiiyantlukwano eziliqela. Eyona ethandwa ngabo - S90 kunye S90B. Bekukho S90i imodeli, S90D kunye S90f, kodwa Asikhange sifumane ukwamkeleka ngokubanzi kwaye ngoku phantse ziphinde zenzeke.

Model nge postfix «B» ezahlukeneyo ukusuka 'nineties "yesiqhelo rhoqo ngokubanzi kuluhlu. Kwakhona, umahluko ebalulekileyo ukusungulwa abathetha Isalathisi sindisa zombane. Ixabiso elicetyiswayo ngamandla aphezulu wokukhulisa column datha ku ezahlukene watts-20 ukuya kwi-90. Kufuneka kuqatshelwe ukuba "Radio» S90, S90B (kunye nezinye iinguqulelo) baba imifuziselo zokuqala lweenkqubo ive bazifezekisayo iimfuneko zamazwe ngamazwe yezixhobo didi Hi-Fi.

design

Izindlu, leyo Uvingca ikholam S90 ngokuyimfuneko eziziingxande ukuba egumbini etywiniweyo eyenziwe ichipboard. Ukujamelana into veneered ngamaplanga anqabileyo. Iindonga kwiikholam Ebubanzini ifikelela-16 mm, indawo yolawulo phambi wenziwe ngamaplanga-22 mm ubukhulu. Iindonga yezindlu yangaphakathi amalungu ezidibene izinto ezikhethekileyo ukwandisa ngqongqo namandla kwesakhiwo, kodwa musa ukuthintela izinga lesandi.

Xa sijonga phambili isixhobo, izithethi zicwangciswe ngendlela ulandelayo (ukusuka phezulu ukuya ezantsi): tweeter, midrange kunye woofer. Kwakhona kwiqela lenjongo phambi umhlathi S90 uyakwazi ukubona ishedyuli impendulo frequency (impendulo frequency) kunye reflex umngxuma. Ngoxa impendulo frequency na ngaphezulu okanye ngaphantsi (ngokuxhomekeke ukuma model), lo inverter isigaba usoloko ngezantsi. Yenziwe yokucingela efanelekileyo yoyilo ukuphulaphula ngcono kunye nokunika imihlathi bass elungileyo.

Umhlathi S90: Ukucacisa

Xa sithatha umzekelo njengesiqhelo S90, ngoko bamisa intloko olutshintshayo radiation ngqo. Ngokungakumbi, i-high-10GD intloko 35, eliphakathi-15GD intloko 11A kunye ephantsi amaza intloko-30GD 2 (in imifuziselo kamva - 75GDN-1-4).

inkqubo ive iye ababili nabalawuli sokuwanyusa kwinqanaba nokuzala MF kunye HF kuluhlu ukusuka 500 ukuya 5000 Hz kwaye ukusuka ku-5 ukuya ku-20 kHz. liqhina nganye liyagungqa kwizikhundla ezintathu ezisisigxina. I "0" uphawu ukusuka crossover akukho miqobo, kwaye inikezelwa ngqo entloko ahambelanayo. Xa usebenzisa kwizikhundla "-3 dB" yaye "-6 dB" signal okuncitshiswe 1.4 no 2 phinda-phinda, ngokulandelelana, xa kuthelekiswa kwisikhundla "0". Ngokutshintsha umlawuli ekhethiweyo ungenza utshintsho ngamazwi yesandi.

Ukuyiveza umthamo kwiikholam S90 - 90 watts, ngelixa wesiqhelo - watts 35. Isalathisi ukumelana ababezibiza zombane kwinkqubo isithethi ibekwe kwi-4 ohms, kunye noluhlu rhoqo ekhoyo yokuvelisa, iyahluka kuluhlu ukususela 31.5 Hz 20 kHz. Wesiqhelo uxinzelelo isandi ke S90 - 1.2 Pa. Kubalulekile ukuphawula ubungakanani ngokwaneleyo encomekayo, umhlathi omnye - 71,0 x 36,0 x 28.5 cm, yaye ingqimba iyonke kwenkqubo yonke ifikelela 30 kg.

Scheme AC kunye uqhagamshelwano ukuya kumthombo isandi

Ukuze uqonde ukuba okanye hayi ukuzibandakanya ekuqukumbeleni nayiphi na inkqubo ephilileyo, kufuneka uhlole zonke iinkalo iinkcukacha kunye nezixhobo. Ngezantsi electric wesiphaluka S90 kwimiqolo. Qonda ukuba, wonke umntu nokuba abo basandula kuqalisa ham irediyo, kufuneka nje ukuba ubuncinane nolwazi olusisiseko.

Omnye umba obalulekileyo uqhagamshelwano oluchanekileyo kwisithethi. Ngapha koko, ukuba kukho into engahambi kakuhle, nokuba na uxhulumanisa, awukwazi, banqwenela ukuzisa phantsi izixhobo. Ukuze siqonde ukudibanisa indlela izithethi ngayo S90, akukho mfuneko ukuba ube yobungcali. Eyona nto ibalulekileyo kukuba ube ngumthombo isandi kunye ubuncinane watts 20 (oku kungenzeka isandi ayikho phezulu ngokwaneleyo amagumbi ezinkulu), kodwa akukho watts ngaphezulu kwama-90. Kwimeko kwamandla msindo amaxabiso kwemfuneko elivumelekileyo umsebenzisi ukuze ukunqanda umsindo ngenxa yokusilela yayo. Ukuqhagamshela iingcingo ezifunekayo eqhelekileyo ukuba izithethi ukuba sidityaniswe iiclamps kwi isithethi ngasinye kunye umsindo. Imeko ephambili ukudibanisa ezichaseneyo echanekileyo.

Ukugqityezelwa 35AS-012

Njengoko kucaca ukusuka inkcazo engasentla, kukodwa uye iinkcukacha inkqubo isandi elungileyo yaye uyakwazi kwiindawo zoluntu nokuba ezincinane 'ujingi ". Kodwa ukusetyenziswa ikhaya umculo othanda kakhulu yaza yahluzwa ukhetha ukuguqula izithethi S90 ngezandla zabo. Kwaye ngenxa yokuba eziqokelelwe kwiminyaka engaphezu kwama amabini (okanye amashumi amathathu) eyadlulayo, le "Radio" inkqubo inkampani ive sele ngaloo minyaka abazange babe umgangatho ukwakha ophezulu kunye nezinto ezisetyenziswayo.

lokuguqula

Xa kunjalo, ukuba isithethi kwathengwa / imeko esetyenzisiweyo kwaye okwangoku beluqhuqha kakuhle ebomini, kufuneka unike intsingiselo ukubonakala. Ukuze wenze oku, kufuneka ibattery ikholam S90 ngaphambili ukubeka nabo "kungasemva".

Xa kufuneka kuqatshelwe yokususa isithethi ukuba oluvela rhoqo kunye nentloko midrange iqhotyoshelwe umzimba usebenzisa izikrufu efanayo njengoko mesh entle kunye akhande. Woofer ifakwe ngokwahlukeneyo, kwaye kufuneka kube silumke umonakalo xa ziba ngcono.

Oku kulandelwa kume reflex emva kokususa ikepusi yayo. Ekubeni iinkcukacha yeplastiki, kubalulekile ukuchaneka ubuninzi ukuba benza uhlukane kuyanda.

Nabalawuli HF / MF dismantle kulula kakhulu kunokuba ibonakala. Konke oko kuya kufuneka benze - kukususa ngononophelo iminqwazi zokuhombisa ukuba embindini esisebenza nganye. Emva koko, usebenzisa screwdriver, ukhulule amehlo esijijwayo avuleka, kwaye ukususa iinqanam ngokwayo. wesampula seplastiki kufuneka uphakanyiswe ngenyameko kuphuma kumacala amabini kunye nezinto tyaba kwaye bakufumana, bathi ke abanye phantsi kwawo, ukhulule izikrufu ezine. Emva koko, lo attenuator ayityhale kwi izithethi S90, musa ukulibala unsolder kwi lokucoca ulwelo.

Iingxowa yomqhaphu ngaphakathi emzimbeni, kufuneka ukuba ufumane. Kwakhona, ukuba umnini sangaphambili izithethi akazange azilibale ukuba zizibuyisele kwindawo xa kuthe calulo.

Kuyinto panel ngaphambili unsolder kunye izihluzi ukusuka imveliso umva kwicala AC, emva kuyimfuneko ufuduke izivalo izikrufu. Ngoku uyakwazi ukususa i panel kunye kwiitheminali eziqhotyoshelweyo.

Imbonakalo nomzimba

Ukuba emkhusaneni kunye ngegolide bokuhombisa 'udiniwe "ezithethi, kuyimfuneko ukuba Ndiyakubalungisa ulipeyinte, pre-sanded kwaye degreased. Oku kuya kunika izithethi amathayara ingqondo. S90 izindlu column na ozithukululeyo na ixesha, kwaye oku kukhula oyifunayo. Oku kuya kubangela ukuba ngcono isandi woofer.

Oku kungenziwa ngeendlela ezahlukeneyo, kuquka ukufakelwa spacers ezongezelelweyo kunye neekona ngaphakathi. Kuyimfuneko ukuba banikele ingqalelo ukutywinwa onke amalungu kunye beentanda usebenzisa imibhobho sealant oluqhelekileyo. Yonke into glue amagwebu udonga zombilini (ngaphandle ngaphambili), nto leyo eza kwandisa umthamo we yokugqibela.

Ngekhompyutha kunye lokucoca ulwelo

hams abanolwazi bayacetyiswa ukuba endaweni izithethi olusezantsi ukuqhagamshela iterminal kwi jikelele uhlobo yesiphelo ngegolide engathi ngumfanekiswana izihlanganisi. indawo yokufaka kuyafuneka ukuba nokuthambisa isixhobo sealant wayifaka kwiqela lenjongo endaweni kunye iiclamps.

kunikwa ingqwalasela kufuneka ihlawulwe kunye namacebo odiyo. Ukuba saqhotyoshelwa umzimba ngezikhonkwane zesinyithi, ucwangciso lokucoca uya kuba kude. Kukho iimeko apho icebo lokucoca sele abizelana ndawonye ngomhla kwipleyiti yesinyithi. Yilungise kufuneka ukudlulisela zonke iiyunithi kwiqela lenjongo le ngamaplanga. kumphathi wesekethe lokucoca zingatshintshwa kwi-mveliso ngenxa parameters ezahlukeneyo ezithethi, ngoko umele aqinisekise ukuba zonke eziqokelelwe ngokungqinelana GOST. Ukuba ikhona kwi webs filter, kufuneka unsolder kwaye endaweni, umzekelo, intambo OFC kunye necandelo indawo umnqamlezo 4 mm ^2. Kufuneka zisuswe wesekethe attenuator, ukusukela nje sigqwethe isandi kwaye endaweni ngcingo kusetyenziswa ukudibanisa izithethi lokucoca ulwelo.

Kuba woofers ezifanelekileyo wire icandelo indawo ye-4 mm ² ukuya midrange - ummandla 2.5 mm ² ukuze tweeter - ummandla we-2 mm ^2. Emva izenzo ezinjalo elula kufuneka ukuyicoca umva endaweni avale amagwebu.

Izithethi kunye nezinye "ngokweenkcukacha"

Somlomo makaselenquthulwa amatywina ezintsha. Oku kungenziwa ngoncedo cheap okanye waphila nje zincede abo mouse computer. Le yeyona ndlela ilula. Emva koko kufuneka kubabuyisela kwizihlalo zabo baza wabeka laths yegridi yenkcukacha.

Phambi kokutshintsha nabalawuli kufuneka vypayat kubo bonke ukuxhathisa. Ukuba uzifakelele endaweni qiniseka ukusebenzisa sealant, kwakunye ngexesha lesigaba ufakelo inverter.

Xa zazo elula column S90 sizuze ubomi obutsha. umgangatho isandi iphezulu kakhulu, phezu kwazo nendleko eziphantsi. Ngenxa yoko, sinokuthi xa kukho imali ku ifomati ive eninzi 2.0, ungasebenzisa i ukhetho efanayo kwaye abe umnini nebhongo proven NJENGOKO "Radio» S90. Ukuba kunjalo kwenzeka ukuba kuphela isiqingatha izithethi ezikhoyo, ungakhathazeki. Ngapha koko, kuyaphawuleka ukuba umhlathi S90, ifoto apho zifumaneka phantse naziphi umsindo site fans amaxesha Soviet, oko kungenziwa eziqhutshwa enye kwaye ngelo xesha linye anike nemiphumo emihle.
