Izikhulisa-zwi zezinkulungwane ezingama-70-90. zł - ingxenye II
Umagazini kaMashi we-"Audio" unikeza ukuhlolwa okuphelele kokuqhathanisa kwezikhulumi ezinhlanu ebangeni lentengo lama-ruble ayizinkulungwane ezingama-70-90. i-zloty. Ngokuvamile, imikhiqizo enjalo ebizayo yethulwa ekuhlolweni okuhlukene, uma kuphela ngenxa yesikhala esithathwe incazelo yemiklamo eyinkimbinkimbi futhi ewubukhazikhazi. Nokho, "I-Young Technician" ithatha ithuba ukwethula lesi sihloko esithakazelisa kakhulu ngendlela emfushane evumelana nefomethi yaso.
Isipikha ngasinye sethulwe sihluke ngokuphelele, sibonisa ukuzimela okufinyelele kude kwabaklami nezinkampani futhi ngaleyo ndlela nobubanzi bezixazululo ezingaba khona esinazo emkhakheni wobuchwepheshe be-acoustic. Sethule okuhle nokubi komklamo we-Avanter III wenkampani yaseJalimane i-Audio Physic. Manje sekuyisikhathi se-SOPRA 3 evela ku-Focal. Amamodeli amathathu asele azovela ngokulandelana kwezinhlamvu ezigabeni ezilandelayo. Uma unentshisekelo encazelweni enemininingwane eminingi yakho konke okuhlanu, kokubili ngokuya ngesu, ukubukeka nobukhulu, kanye nemibiko yokulalela, sicela uvakashele Umsindo 3/2018.
Gxila PHEZULU 3
Ngaphezulu kweminyaka engamashumi amabili, i-Focal Utopia edumile ibe yingxenye ebalulekile yochungechunge olusezingeni eliphezulu ezizukulwaneni ezilandelayo. Eminyakeni embalwa edlule, i-Focal ibilokhu yethula amamodeli e-Sopra kulokho kunikezwa, ngezindlela eziningi ezifinyelela izinga le-Utopia.
Sethula izisombululo ezivezwe ochungechungeni lwe-Sopra, i-Focal yaqhosha ngezinto ezintsha ezingatholakali ochungechungeni lwe-Utopia. I-Sopra 2 yethulwa kuqala (iwine umklomelo we-EISA), yalandelwa kafushane i-Sopra 1 encane (ebekwe yi-stand-mount), futhi ngonyaka odlule inkulu kakhulu ochungechungeni lwe-Sopra 3.
Imodeli ephawulwe ngonxantathu ifana kakhulu ngokuma nokucushwa ku-Sopra 2. Ihluke ngokuyinhloko ngobukhulu be-woofers futhi, ngokufanele, ngobukhulu bekhabhinethi. Izipikha zitholakala ngendlela ejwayelekile kuma-Focals amaningi - i-midrange (16 cm) "iphakanyiswe" ngaphezu kwe-tweeter, ngoba iphakeme ngokwanele (izindlebe zomuntu ohlezi phansi), futhi phansi kukhona okukhulu. ingxenye ye-module woofer (enepheya lezipikha ezingama-20 cm). I-Electroacoustically, isekethe imvamisa inamabhande amathathu.
Ukugoba yonke iKhabhinethi ukuze izimbazo zesipika zazo zonke izigaba ziphambane phambi kwesipika, kancane noma ngaphansi endaweni yokulalela, futhi kunomkhuba omude kumiklamo ye-Focal esukela esizukulwaneni sokuqala se-Utopia futhi isaqhubeka nanamuhla e-Utopia. , uchungechunge lwe-Sopra ne-Kant. Kulowo nalowo wabo, lesi sakhiwo senziwe ngokuhlukile, ngokwengxenye kunqunywa usayizi nesabelomali, kodwa futhi ngamathuba amasha nokushintsha imfashini. Ku-Utopias, sinokuhlukaniswa okucacile, futhi ku-Sopry, izinguquko ezibushelelezi phakathi kwamamojula ngamanye; noma ngabe ukusebenza kwe-Utopia kudinga kakhulu izinto ezibonakalayo, kudinga abasebenzi futhi kunobukhazikhazi, izimo zeSopra zingezesimanjemanje. Ukusetshenziswa kwezingxenye ze-aluminium ezixutshwe (hhayi i-chromed noma i-oxidized), isici se-Sopra, kunezela ekuvezeni kwayo, futhi kanye nemibala ethile, ibhekisela kancane kwisitayela sezimoto zezemidlalo. I-dome ye-tweeter ihlale ivikelwe nge-mesh yensimbi - lapha kungcono ukunganciki ekuxwayiseni komsebenzisi, ngoba kuzobiza kakhulu ukulimaza i-beryllium dome. Mayelana nolwelwesi, i-Sopra ayiwagodli amasu angcono kakhulu we-Focal - i-beryl (ku-tweeter) kanye nesemishi le-W (ukwakheka kwesemishi lezendlalelo zangaphandle ze-fiberglass kanye negwebu eliqinile phakathi kwazo). E-Sopry, izinguquko eziningi zenziwa kumshayeli we-midrange, okuhlanganisa, phakathi kwezinye izinto, ukumiswa okudambisiwe okukhulu, kanye nesistimu yezibuthe eklanywe ngokunembe, eyenza kube nokwenzeka ukuguqula iphrofayili ye-diaphragm kusukela ku-conical yangaphambili kuya ku-exponential. , kweminye imingcele ifaneleka kakhulu isipika esiphakathi nendawo. Igumbi elide elinephrofayili elimanzi selilungiselwe i-tweeter - umhubhe ogcina endaweni encane, ehlotshiswe nge-grille ebanzi ngemuva. Lolu uhlobo lwehaba lwefomu ngaphezu kokuqukethwe. Ukudambisa igagasi elisebenza kahle nelingena-resonance elisuka ngemuva kwedome bekungeke kudinge ukunwetshwa okunjalo, kodwa bekuyithuba elihle, ngoba imojula ye-tweeter nayo isebenzela "ukugoba" isakhiwo.
Ikhabhinethi igobile iqonde (ngenxa yokuqondanisa kwezimbazo zesipika esikhulu ezishiwo ngenhla) futhi inezinhlangothi ezigobile (okunciphisa amagagasi amile ngaphakathi). Iphinde ibe nengaphambili eligobile kanye ne-radius enkulu, izinguquko eziyindilinga phakathi kwezindonga eziseceleni nangaphambili (sibonga lapho amagagasi egeleza ephuma emzimbeni ngaphandle kokubhampa emaphethelweni acijile). I-plinth yenziwe ngengilazi engamasentimitha amabili. Umzimba ngokwawo uphakanyiswa futhi utshekisiwe yipheya lezisekelo, ngesikhathi esifanayo wenza ukuqhubeka komhubhe we-inverter wesigaba.
I-Sopra 3 ibukeka ilula ngokwanele ngenxa yesimo sayo, kodwa ngo-70kg inzima kakhulu kwemiklamo emihlanu uma iqhathaniswa.
Isebenza kanjani, i.e. imishini elabhorethri
Izici ze-Sopra 3 zibonisa i-bass boost ecacile, ephakamisa ukuthi lesi sipikha kufanele sisetshenziswe emakamelweni amakhulu. Ngesikhathi esifanayo, ububanzi obubanzi be-medium frequencies bulinganisela kahle kuwo. Kububanzi obungu-500 Hz - 15 kHz, hhayi kuphela eduze kwe-eksisi eyinhloko, isici sigcinwa kububanzi obuncane buka-+/- 1,5 dB. Ukusabalalisa kwefrikhwensi ephezulu kuhle kakhulu. Emazingeni aphansi, kukhona ukuncishiswa kwe--6 dB kusuka ezingeni eliphakathi nemvamisa engu-28 Hz - umphumela omuhle kakhulu. Njengoba kulindelekile, sibhekene nedizayini engu-4-ohm enokumelana okuncane okungaba ngu-3 ohms (ku-100 Hz), ngakho-ke silungele ukusebenza nezikhulisamazwi "ezinempilo". Umkhiqizi uncoma amandla ebangeni lama-watts angama-40-400, okubonakala kunengqondo (amandla alinganisiwe angalinganiselwa ku-200-300 watts).
