I-ACADEMY Chario SERENDIPITY

I-Academy Serendipity, naphezu kokuba ingaphezu kweminyaka eyishumi ubudala, ayigcini nje ngokuhlala emnikelweni we-Chario, kodwa iseqophelweni eliphezulu. Lo mklamo wesipika ungowohlobo oluthile, nakuba ulandela emuva ezinkomba zangaphambili zika-Chario, izikhulumi ze-Academy Millennium Grand. Ngokusho komkhiqizi, i-Serendipity iyisiphetho sesipiliyoni kanye nokucabangela okuqoqwe kusukela ekuqaleni kokuba khona kwenkampani, i.e. kusukela ngo-1975. Inani elikhulu kakhulu le-acoustic lifihliwe ekucushweni okukhethekile okungakwazi ukukhonjwa kuphela ngenani lezikhulumi. nezinhlobo zazo ezihlukene, kodwa ngendlela ezisebenzisana ngayo ngaphandle kwephethini "yezindlela eziningi".

Umzimba ubukeka njengesigxobo esikhulu sokhuni, kodwa lokhu kuyingxenye yawo kuphela.

Ngakho-ke, izindonga ezisemaceleni nezingaphezulu zenziwe ngamabhodi, kuyilapho ukuqiniswa kwangaphambili, ngemuva nangaphakathi kwenziwa nge-fiberboard. Kuneziningi zazo, ikakhulukazi esigabeni se-subwoofer, lapho kukhona amandla amaningi asele okuthambisa, kanti kokunye asebenza njengama-partitions, enza amagumbi azimele e-acoustic asebenza kuma-subrange ahlukene. Isakhiwo sonke empeleni sihlukaniswe izingxenye ezimbili, ezilingana noma ezilingana ngobude. Ngezansi kunengxenye ye-subwoofer, kanti phezulu kukhona abanye abashayeli abane. I-Chario ayiqinisi indima yokhuni lwemvelo ekufezeni umsindo wemvelo, ikakhulukazi ukunamathela emcabangweni wokunikeza izikhulumi indima "yezinsimbi"; ikholomu kufanele ibhekane, futhi ingadlali - lezi yizinto ezihlukene. Izinkuni, noma kunjalo, zinemingcele emihle yemishini, futhi okubaluleke kakhulu ... iphathwa ngale ndlela, ibonakala inhle.

Imizila emihlanu ngezinjongo ezithile

Isivumelwano samaqembu amahlanu asivamile. Ngisho noma sengeza ama-nuances futhi, ngokucabangela okunye okucatshangelwayo, siyavuma ukuthi lolu uhlelo lwezindlela ezine nengxenye (ezizokwenza ukuhlaziya kube nzima nakakhulu ...), sibhekene nomklamo ohamba kude. ngale kwezinhlelo ezisetshenziswa abanye abakhiqizi . Ukwakhiwa kwamasekhethi e-multiband kuphoqelelwa ukungakwazi kwesikhulisazwi ngasinye - noma ngisho namapheya ezinhlobo ezahlukene zabashayeli (ngezindlela ezimbili) - ukwakha idivayisi yesipikha esizohlinzeka ngesikhathi esisodwa umkhawulokudonsa obanzi, amandla aphezulu kanye nokuhlanekezela okuphansi. Kodwa ukuhlukaniswa kube izigaba ezintathu - ngokwemibandela ebizwa ngokuthi i-bass, i-midrange ne-treble - kwanele ukufeza cishe yonke imingcele eyisisekelo (izikhulumi ezihloselwe ukusetshenziswa ekhaya). Ukunwetshwa okwengeziwe kungase kube ngenxa yenhloso yokuzuza izici ezithile ze-sonic kanye nezakhiwo. Yile ndlela kanye esebenza ngayo.

Uhlelo olubanzi lwesipika se-Serendipity alusetshenziswa nje kuphela ukuthuthukisa ukucutshungulwa kobubanzi obuncane be-acoustic ngama-transducer akhethekile, kodwa futhi, ngokuxakayo, ukusebenzisa imiphumela "eseceleni" evela ekusetshenzisweni kwama-multi-band systems, ezibhekwa njengeziyingozi kwabanye abakhiqizi futhi zincishiswa kufika ezingeni eliphezulu kakhulu. Umakhi we-Serendipity uhamba ngendlela ephambene impela nomakhi ofana no-Cabas, lowo, ngosizo lwezinhlelo ezigxilile, ozama ukuzuza umphumela "webhola elishayayo", umthombo ohambisanayo wawo wonke amafrikhwensi, akhipha isici esifanayo i-engeli ebanzi kakhulu endizeni ngayinye (okuwumgomo wokuhleleka okugxilile zonke iziguquli). Ukususwa kwama-transducer komunye nomunye kuholela ekushintsheni kwezici ezingaphandle kwe-eksisi eyinhloko (ikakhulukazi endizeni eqondile lapho kwenzeka khona lokhu kususwa). Ngisho noma lokhu kuncishiswa kubonakala kuzici nezimbazo ezidlulela ngalé kwendawo yokulalela, amagagasi ahamba ngalezi zindlela abonakala ezindongeni zegumbi azophinde afinyelele kumlaleli futhi azothwalisa umbono webhalansi yethoni yesithombe sonke. . Ngakho-ke, ngokusho kwabakhiqizi abaningi, kubalulekile ukugcina ukuzinzile, kuye ngokuthi imvamisa, okuthiwa impendulo yamandla.

Ngakolunye uhlangothi, lokhu kunciphisa okungenzeka kungabhekwa njengethuba elihle lokunciphisa ukuphakama kwamagagasi abonisiwe, okungukuthi, ukunciphisa ukucabangela kanye negalelo labo ekudalweni kwesithombe endaweni yokulalela. Uma sibheka i-Serendipity, asiboni "okudidayo" okusobala ohlelweni lwesipika. I-tweeter itholakala eduze kwe-midrange, enye eduze kwe-midrange yesibili (ehlungwe kancane kancane), yona, eseduze ngqo ne-bass. Kodwa-ke, ngamagagasi amafushane aphakathi kwefrequency, okuzoba ama-crossover frequencies lapha, ngisho namabanga anjalo phakathi kwama-transducers asho ukuthi kuma-engeli amadigri amaningana, futhi ngisho nangaphezulu - amashumi amaningana, ukuncishiswa okujulile kuvela ezicini. Ububanzi bawo buncike ekukhuphukeni kwemithambeka yezimpawu zezigaba ngazinye, ezihlobene eduze nendlela izikhulumi ezisebenzisana ngayo.

Nansi enye ingxenye yephazili, okungukuthi ukusetshenziswa kokuhlunga okuthambile. Into elandelayo ukusetha imvamisa ye-crossover eduze komunye nomunye - phakathi kwe-bass kanye ne-pair of midrange woofers cishe i-400 Hz, futhi phakathi kwe-midrange (ehlungiwe kakhulu) kanye ne-tweeter - ngaphansi kwe-2 kHz. Ngaphezu kwalokho, kukhona ukubambisana phakathi kwepheya labashayeli be-midrange (kungenjalo bahlungiwe, kepha izici zabo ziseduze komunye nomunye ebangeni elibanzi kakhulu, futhi i-midrange ehlungiwe ephansi nayo isebenzisana ne-tweeter) futhi, ekugcineni, sinezimpawu eziningi ezigqagqene futhi ezigqagqene. Kunzima kakhulu ukunquma izici ezilindelekile (hhayi eziqondile) zomakhi kuphela eduze kwe-eksisi eyinhloko esimweni esinjalo, futhi akunakwenzeka ukuzuza ukuzinza kuma-engeli amakhulu. Kodwa-ke, umklami u-Chario wayefuna ukufeza umphumela onjalo - ubiza ngokuthi "ukuhlobisa": ukuncishiswa kwemisebe evela eksisi eyinhloko, endizeni eqondile, ukuze kuncishiswe ukubonakaliswa okuvela phansi nophahla.

Ukucushwa kwe-Woofer

Esinye isixazululo esiqondile esisahlobene nokulawulwa kokubonisa ukucushwa kwezipikha kububanzi be-subwoofer. Ingxenye, umkhiqizi ayibiza ngokuthi i-sub, itholakala phansi kakhulu kwesakhiwo. Iphuzu lapha alikho kwezinye izici zalo (okuzoxoxwa ngakho kamuva), kodwa eqinisweni lokuthi umthombo wemisebe utholakala ngaphezu kwesitezi (singabona kuphela "amafasitela" anomthunzi wegumbi elingaphansi, i-facade nezindonga ezisemaceleni). Ngakolunye uhlangothi, i-woofer ishiywe yinkampani kusukela phansi kuya phezulu, ijika lifana nalokho okubizwa ngokuthi. amajika e-isophonic, kodwa lokhu akulandeli esiphethweni (naso) esilula sokuthi kufanele "silungise" izici zokuzwa kwethu ngale ndlela (esingayilungisi nganoma yiziphi izinsiza-kuzwa lapho silalela imisindo yemvelo nomculo ophilayo). Isidingo salokhu kulungiswa u-Chario sisuka ezimeni ezehlukene esilalela kuzo umculo - bukhoma futhi ekhaya, kusuka kupheya lezipikha. Lapho silalela bukhoma, amaza aqondile nabonisayo ayasifinyelela, okuthi ndawonye akha umbukwane wemvelo. Kukhona futhi ukucabangela ekamelweni lokulalela, kodwa kuyingozi (ngakho-ke i-Chario iyanciphisa ngokusebenzisa izindlela ezichazwe ngenhla), ngoba. dala imiphumela ehluke ngokuphelele, ingakhiqizi izimo ze-acoustic zokurekhoda nhlobo, kodwa okubangelwa izimo ze-acoustic zegumbi lokulalela. Izici zesikhala sokuqala sokuqoshwa zifakwe ngekhodi emsindweni odlalwa futhi ngezipikha ngamagagasi ahambayo aqondile (isb. ukuguquguquka). Ngeshwa, zivela kuphela ohlangothini lwezipikha, futhi ngisho nokushintsha kwezigaba okunganwebeka futhi kujulise indawo yethu ngeke kusilungise ngokuphelele isimo. Ngokocwaningo luka-Chario, umbono wethu ugxile kakhulu kumafrikhwensi amaphakathi, ngakho-ke adinga ukuncishiswa ngokwezinga elithile ukuze kutholwe ubumvelo obunokwenzeka bawo wonke umcimbi womsindo, kokubili ezizindeni zethoni nezendawo.

Lapho omunye edonsa, omunye uyaphusha

Idizayini yengxenye ye-Serendipity subwoofer iyisahluko ngokwayo. Lapha sibhekene ne-push-pull system, engavamile ukusetshenziswa namuhla (ngomqondo othize obanzi, obizwa nangokuthi i-compound noma isobaric). Leli ipheya lama-woofer axhunywe ngokumshini “i-diaphragm ku-diaphragm” kanye nangogesi ngendlela yokuthi ama-diaphragm awo asuke aqonde ohlangothini olufanayo (okuhlobene nomzimba, hhayi ubhasikidi ngamunye). Ngakho-ke, lawa ma-dynamics awacindezeli umoya ovaliwe phakathi kwawo (kungakho igama elithi isobaric), kodwa liwuhambise. Ukuze wenze lokhu, uma benesakhiwo esifanayo futhi ukuphenduka kulinyazwa ohlangothini olufanayo, kufanele baxhunywe ngokuphambene (komunye nomunye) ama-polarity (ngokumaka iziphetho zabo) ukuze ekugcineni basebenze esigabeni esifanayo (lapho ikhoyili ijuliswa enye) ohlelweni lukazibuthe, ikhoyili yenye iyaphuma). Ngakho-ke igama elithi push-pull - lapho isikhulumi esisodwa "sidonsa", esinye "siphusha", kodwa basasebenza ohlangothini olufanayo. Okunye okuhlukile kulolu hlelo ukuhlelwa kukazibuthe kuya kuzibuthe, kanti okunye okusebenza nomthelela ofanayo we-sonic ukuhlelwa lapho izipikha zibekwe esinye ngemuva kwesinye ohlangothini olufanayo (umazibuthe wangaphandle oseduze nozibuthe). indawo engaphakathi). Khona-ke izikhulumi kufanele zixhunywe ku-polarity efanayo - uhlelo olunjalo, nakuba luse "isobaric", akufanele lusabizwa ngokuthi i-push-pull, kodwa, mhlawumbe, inhlanganisela.

Ngizobhala ngomehluko omncane phakathi kwalezi zinketho ekugcineni, kodwa iyiphi inzuzo eyinhloko yalesi simiso? Uma uthi nhlá, lesi silungiselelo singabonakala sengeza ukucindezela okukhiqizwa yizo zombili izikhulumi. Kodwa akunjalo - yebo, uhlelo olunjalo lunamandla aphindwe kabili (luthathwa ngamakhoyili amabili, hhayi elilodwa), kodwa luyingxenye esebenzayo ("ingxenye" ​​yesibili yamandla anikezwe isipikha sesibili ayikhulisi ingcindezi). Pho kungani sidinga isisombululo esinjalo esingasebenzi kahle? Ukusetshenziswa kwabashayeli ababili ohlelweni lwe-push-pull (inhlanganisela, isobaric) kudala uhlobo lomshayeli oyedwa onemingcele ehlukene. Uma sicabanga ukuthi iqukethe ama-transducer amabili afanayo, i-Vas izokwehliswa ngesigamu futhi i-fs ngeke inyuke, ngoba sinesisindo sokudlidliza esiphindwe kabili; Ama-Qts nawo awanyuki, ngoba sine "drive" ephindwe kabili. I-Summa summarum, ukusetshenziswa kwe-push-pull ikuvumela ukuthi uphindaphinde ivolumu yekhabhinethi (amasistimu amaningi - okuhlanganisa avaliwe, i-bass-reflex, i-band-pass, kodwa hhayi imigqa yokudlulisa noma i-horn cabinet) ukuze uthole isici esithile, uma kuqhathaniswa nokusebenzisa isipikha esikhulumazwi esisodwa (o imingcele efanayo ne-push-donsa imibhobho).

Ngenxa yalokhu, ngevolumu engenkulu kangako (ngikukhumbuza ukuthi imojula ephezulu isebenzela ezinye izigaba), sithole imvamisa ephansi kakhulu yokusika (-6 dB ku-20 Hz).
