Ubulula obucwengekile noma inkani efanele isenzo esingcono?
Ubuchwepheshe besikhulisazwi buye bavela eminyakeni eyikhulu. Kakade ekuqaleni komlando wayo, kwatholakala ukuthi ukucutshungulwa kwayo yonke i-acoustic spectrum, ngokuhlanekezela okuphansi ngokwanelisayo, ngesikhulumi esisodwa (transducer) kunzima kakhulu, uma kungenakwenzeka. Kuvele ukuthi kudingekile ukuthi kuklanywe izipikha ezihlanganisa ama-transducer akhethekile ekucubunguleni ama-sub-band athile.
Intuthuko ihambe ngale ndlela, futhi nayo abakhiqizi bezikhulisazwi abangama-99%, benza ingcebo engenakulinganiswa yezinhlelo zezindlela ezimbili, ezintathu, ezine kanye nangaphezulu, ngezinye izikhathi eziyinkimbinkimbi kakhulu, eziyihaba, ezithuthuke kakhulu - noma sunguliwe. kubonakala kubafundi abayizimfundamakhwela abashicilelayo ukuthi uma “imigwaqo” eminingi ilungiswa kangcono mhlawumbe ... kumakhasimende anjalo. Nokho, izixazululo ezinengqondo zikhona, lapho inani lezindlela kanye nenani lama-transducer (akufani - kungaba khona ama-transducer angaphezu kweyodwa endleleni ngayinye, okuvame ukuba njalo esigabeni se-LF) ngokulingana nobukhulu be-transducer. isakhiwo kanye nokusetshenziswa kwayo okuhlosiwe.
I-Bidromic encane
Ubuncane bubhekwa njengobuncane obucishe bubonakale uhlelo lwamazwe amabili, ngokuvamile ehlanganisa i-midwoofer kanye ne-tweeter. Uhlelo olunjalo, olusekelwe kuziguquli ezisezingeni eliphezulu zazo zombili izinhlobo, luyakwazi ukusebenza cishe kulo lonke uhla lwamafrikhwensi. Kodwa-ke, kunzima kakhulu ukufeza amazinga evolumu aphezulu kakhulu ngayo, ngoba i-mid-woofer, ene-diameter emaphakathi (ukwazi ukuphatha ama-midfrequencies), noma ikwazi ukuphatha ama-bass, ayikwazi ukumunca phezulu kakhulu. amandla kulobu bubanzi, ayikwazi ukukhiqiza kabusha i-bass ngesikhathi esifanayo ijule futhi inomsindo. Njengoba sonke sazi, ama-frequencies aphansi kakhulu namandla aphezulu yizikhulumi eziningi ezinkulu, okuyinto, noma kunjalo, ezingasakwazi ukusebenza njengama-midwoofers, kodwa kuphela njengama-woofers, kokubili ngenxa yobubanzi bawo obukhulu kakhulu, nangenxa yezinye izici, ezizenza. more cumbersome. ifaneleka kakhulu ukucubungula okuphansi, kunokuba amaza aphakathi nendawo; ngenxa yalokho, kwakhiwa izinhlelo ezinama-band amathathu, lapho amaza aphakathi acutshungulwa yi-converter ekhethekile - i-midrange.
"Okuhle" ngesikhathi esisodwa
UDavis MV One - bafana bodwa, azisekho izikhulumi lapha.
Imithetho yomdlalo evumela ukuthi udale izipika ezisezingeni eliphakeme ayiqinile, kepha imithetho ejwayelekile, njengokungathi, isungulwe futhi isetshenziswa iningi labaqambi - yiqiniso, impumelelo kuphela, hhayi ngokusho kwabanye. zokupheka. Kodwa njengoba kukhona labo abathanda ukwenza ihaba nge "permeability" futhi baxabanise ukuhlelwa ngokweqile, kukhona labo abalwela ngenkani ukwenza izinto zibe lula, belwela ukuqaliswa. esiphezulu esiphezulu - imibhobho yendlela eyodwa kanye ne-single-converter. Ngakho ngesikhulumi esisodwa.
Yebo, sijwayelene nezisetshenziswa ezidumile, ezincane kakhulu, zekhompuyutha noma eziphathwayo ezingenaso isikhala noma ibhajethi yokufaka isistimu yesipikha esinezindlela ezimbili. Ngakho-ke siyayeka ukusebenza nomshayeli oyedwa (esiteshini ngasinye se-stereo, inqobo nje uma idivayisi iyi-stereo), ngokuvamile incane, ingamasentimitha ambalwa ubude, engafinyeleli ngisho nezindinganiso ezindala kakhulu zemishini ye-hi-fi, kodwa akunjalo. imishini. othi leli gama.
Okuthakazelisa kakhulu imiklamo yendlela eyodwa, okuthi, ngokombono wabaklami bayo futhi, ngokubona kwabasebenzisi bayo abaningi, kufanele nje ibe ngcono kunezinhlelo zamaphasi amaningi, futhi vela phakathi elite target, ngamanani amashumi ambalwa ezinkulungwane ze-zł.
Kulolu daba oluyimpikiswano, sizozama ukuba nenhloso. Yiqiniso, izibalo ngokwazo zibonisa ukuthi ama-multi-band systems aziswa kakhulu abaklami abahlakaniphile emhlabeni wonke, kodwa ake simele "okufanelekile kohlangothi olulodwa." Okungenani ukuze ukhumbuze abathandi bemiklamo eyinkimbinkimbi kakhulu ukuthi i-multipath ayisona isiphetho ngokwayo, kodwa isidingo esidabukisayo nokukhetha okuncane kobubi. Isimo singajabulisa kakhulu ukube bekungenzeka ukucubungula ibhendi yonke ngombhobho owodwa, njengoba ukuhlukaniswa kwebhendi ibe ama-subband, i.e. ukwethulwa kwe-electrostatic precipitators (i-crossover), ukuhlanekezela. Ukukhishwa kwamabhendi amafrikhwensi ahlukene ngezipika ezibekwe eduze komunye nomunye, kodwa hhayi ku-eksisi efanayo (ngaphandle kwezinhlelo ze-coaxial, ezinobunye ububi ...) kubangela izinkinga ezengeziwe. Kodwa-ke, kuyaqashelwa ukuthi ngezidingo zekhwalithi ephezulu, lokhu akuyona inkinga encane kunalokho obekungagwetshelwa ukusebenzisa umshayeli oyedwa. Kuhlale kuhle ukukhumbula ukuthi akunangqondo ukuwaphindaphinda ngokungenasidingo - kufanele gcina "patency" ngaphakathi kwesizathu kanye nezidingo zezakhiwo ezinemisebenzi ethile kanye nemingcele eqondiwe.
Akunakwenzeka ukwenza umshayeli ophelele ophelele, futhi ohloniphekile (uma kuqhathaniswa namandla ezikhulumi)
kudinga uthando olukhulu, ikhono kanye nokusetshenziswa kwezinto ezinhle kakhulu. Isipikha esigcwele esingu-20 DE 8 (esisetshenziswa ku-MV One) sihlanganisa, phakathi kwezinye izinto, isistimu kazibuthe ye-Alnico ebizayo.
Eqinisweni, okuhle kungaba isikhulisazwi esisodwa esiphelele esiqeda zonke izinkinga ezibangelwa izindlela eziningi. Ngeshwa, isipikha esinjalo, noma "cishe" isipikha esinjalo, naphezu kwemizamo eqhubekayo, ayikho. Konke, ngisho nezipikha ezihamba phambili zobubanzi obugcwele zine-bandwidth encane kunezipikha eziningi, futhi ukusebenza kwazo kukhombisa ukungalingani okukhulu. Kodwa-ke, lokhu akubadikibali abanye abantu, ngoba i-self-hypnosis noma izakhiwo zangempela zama-transducer asezingeni eliphakeme zivumela ukuthi babone okuthile okuhlukile kumsindo wabo, okuthile okukhethekile, ngakho-ke, ngokusho kwabalandeli besixazululo esinjalo. , okuthile okungcono. Ngaphezu kwalokho, ezinye izici zamasekethe anohlangothi olulodwa ziheha ukunaka kwabanikazi bama-tube amplifiers - i.e. ngokuvamile ama-amplifiers aphansi, ngakho-ke awadingi izipika zamandla aphezulu, kodwa asebenza kahle kakhulu. Iqiniso liwukuthi uma i-loud speaker ingadingeki ukuba ibe namandla aphezulu, ngakho-ke ngenxa yezici zokuklama ezihambisana nayo (isibonelo, ikhoyili yezwi elincane elikhanyayo), kulula ukuyifeza hhayi kuphela ukusebenza kahle okuphezulu, kodwa futhi umkhawulokudonsa obanzi. .
Yenza isinqumo
Isipikha esinobubanzi obugcwele esithakazelisa kakhulu nesithuthuke kakhulu sathuthukiswa inkampani yaseFrance i-Davis futhi sasetshenziswa kumbhobho we-MV One. Ukuhlolwa kwabo, eqenjini lemiklamo emithathu yesiFulentshi (eminye emibili inamabhendi amathathu), ngokwesiko ichaza ukwakheka, izilinganiso zomsindo nelebhu, yashicilelwa kumagazini kaJuni (6/2015) womsindo. Ungakwazi ukuqhathanisa futhi wenze umbono wakho siqu ... Into ethakazelisayo, ngisho ngaphandle kwe-tube amplifier.
