ACADEMY Chario SERENDIPITY

Academy Serendipity, kunyangwe iine makore anopfuura gumi, haingorambi iri mukupa kwaChario, asi ichiri pakakwirira. Iyi dhizaini yemutauri ndeimwe yemhando, kunyangwe ichidzokera kumashure kwaChario akambotaura, Academy Millennium Grand vatauri. Maererano nemugadziri, Serendipity ndiyo kuguma kwechiitiko uye fungidziro dzakaunganidzwa kubva pakutanga kwekuvapo kwekambani, i.e. kubva 1975. Iyo yakanyanya kukosha yeacoustic yakavanzwa mune yakakosha gadziriro isingagone kuzivikanwa chete nenhamba yevatauri. nemhando dzawo dzakasiyana, asi nemabatiro avanoita kunze kwepatani ye "multipath".

Muviri wacho unoita sedanda guru, asi izvi zvishoma.

Nokudaro, rutivi uye madziro epamusoro ane chikamu chakagadzirwa nemapuranga, nepo mberi, kumashure uye kusimbiswa kwemukati kunogadzirwa ne fiberboard. Kune akawanda acho, kunyanya muchikamu che subwoofer, uko kune simba rakawanda rasara rekunyorovesa, nepo mune mamwe ese anoita sezvikamu, achigadzira akazvimirira acoustic chamber anoshanda muma subranges akasiyana. Chimiro chese chakakamurwa kuita zvikamu zviviri, zvakanyanya kana zvishoma zvakaenzana mukukwirira. Pazasi pane subwoofer chikamu, uye kumusoro kune mamwe madhiraivha mana. Chario haafungidzire basa rehuni hwechisikigo mukuwana ruzha rwechisikigo, kunyanya kuomerera kune pfungwa yekupa vatauri basa re "zviridzwa"; iyo column inofanira kutarisana, uye kwete kutamba - izvi zvinhu zvakasiyana. Iyo huni, zvisinei, ine yakanaka mechanical parameters, uye inonyanya kukosha ... inorapwa nenzira iyi, inotaridzika yakanaka.

Nzira shanu dzezvinangwa zvakananga

Chibvumirano chemapato mashanu hachiwanzoitiki. Kunyangwe isu tikawedzera nuances uye, tichifunga mamwe fungidziro, tinobvuma kuti iyi ina-nehafu-nzira system (iyo inoomesa kuongororwa zvakanyanya ...), isu tiri kubata nedhizaini inoenda kure. kunze kwezvirongwa zvinoshandiswa nevamwe vagadziri . Kusikwa kwema-multiband circuits kunomanikidzwa nekusakwanisa kwegudzanzwi remunhu - kana kunyange mapeya emhando dzakasiyana-siyana dzevatyairi (mune-nzira mbiri-maseketi) - kugadzira gudzanzwi mudziyo uyo panguva imwe chete kupa yakafara bandwidth, simba guru uye yakaderera kukanganisa. Asi kupatsanurwa muzvikamu zvitatu - zvine mamiriro anonzi bass, midrange uye treble - zvakakwana kuti uwane chero akakosha paramita (matauri akagadzirirwa kushandiswa pamba). Kumwe kuwedzera kunogona kunge kuri nekuda kwechinangwa chekuwana mamwe chaiwo sonic maitiro uye zvivakwa. Aya ndiwo mashandiro azvinoita.

Iyo yakakura Serendipity speaker sisitimu inoshandiswa kwete chete kukwenenzvera kugadzirisa kwega-diki-renji yeacoustic renji neakasarudzika transducer, asi zvakare, zvinokatyamadza, kushandisa "side" mhedzisiro inokonzerwa nekushandiswa kweakawanda-bhendi masisitimu, ayo ari. zvinoonekwa zvinokuvadza kune vamwe vagadziri uye zvinoderedzwa kusvika pakakwirira. Muvaki weSerendipity anofamba akananga kwakatarisana nemugadziri akadai saCabas, uyo, nerubatsiro rwe concentric system, ari kuyedza kuwana mhedzisiro ye "pulsating ball", inobatana sosi yema frequency ese, inopenya yakafanana hunhu pa. iyo yakakura kwazvo kona inogoneka mundege yega yega (inova chinangwa cheiyo concentric kuronga vese vashanduri). Kutamiswa kwema transducers kubva kune mumwe kunotungamira kune shanduko yehunhu kunze kweiyo axis huru (kunyanya mundege yakamira umo kusimuka uku kunoitika). Kunyangwe kana izvi zvikumbiro zvichionekwa pane hunhu uye matemo anotambanudzira kupfuura nzvimbo yekuteerera, masaisai anofamba nenzira idzi anoratidzwa kubva kumadziro ekamuri achasvikawo kumuteereri uye anoremedza maonero ekuenzanisa kwetoni yemufananidzo wese. . Nokudaro, maererano nevakawanda vanogadzira, zvakakosha kuchengetedza zvakagadzikana, zvichienderana nehuwandu, iyo inonzi simba remhinduro.

Kune rumwe rutivi, izvi zvinogona kuderedzwa zvinogona kutorwa semukana wakanaka wekudzikisa amplitude yemafungu anoratidzwa, ndiko kuti, kuderedza kuratidzwa uye kubatsira kwavo pakusikwa kwechifananidzo panzvimbo yekuteerera. Tichitarisa Serendipity, hationi "anomalies" ari pachena muhurongwa hwemukurukuri. Iyo tweeter iri padyo nepakati, iyo iri padyo neyechipiri midrange (yakasefa zvishoma yakaderera), iyo, zvakare, yakanangana neiyo bass. Nekudaro, kune mapfupi mapfupi epakati-frequency mafungu, anove ari crossover frequencies pano, kunyange madaro akadaro pakati pevashanduri zvinoreva kuti pamakona emadhigirii akati wandei, uye zvakatonyanya - makumi akati wandei, kudzika kwakadzika kunoonekwa pane maitiro. Kufara kwavo kunoenderana nekudzika kwemateru ehunhu hwezvikamu zvega, izvo zvine hukama zvakanyanya nemabatiro anoita vatauri.

Hechino chinouya chimwe chidimbu chepuzzle, chinoti kushandiswa kwesefa yakapfava. Chinhu chinotevera ndechekuisa iyo crossover frequency padhuze kune mumwe nemumwe - pakati pebass uye peya ye midrange woofers inenge 400 Hz, uye pakati pepakati (yakanyanya kusefa) uye tweeter - pazasi 2 kHz. Pamusoro pezvo, pane kubatirana pakati pevaviri vevatyairi vepakati (zvikasadaro vakasefa, asi hunhu hwavo hwakarara padhuze nepamusoro pehupamhi hwakakura kwazvo, uye iyo yakaderera yakasefa midrange inopindirana neiyo tweeter) uye, pakupedzisira, isu tine yakawanda. kupindirana uye kupindirana maitiro. Zvakanyanya kuoma kuona zvinotarisirwa (kwete hazvo mutsara) maitiro emugadziri chete pamwe chete neakisi huru mumamiriro ezvinhu akadaro, uye hazvibviri kuwana kugadzikana pamakona makuru. Nekudaro, mugadziri Chario aida kuzadzisa mhedzisiro yakadaro - anoidana kuti "kushongedza": kuderedzwa kwemwaranzi kubva kune huru axis, mundege yakatwasuka, kuitira kudzikisa kuratidzwa kubva pasi nedenga.

Woofer Configuration

Imwe mhinduro chaiyo ichiri kuenderana nekutarisa kudzora ndeye kumisikidzwa kwemagudzanzwi mu subwoofer renji. Chikamu, icho mugadziri anodana sub, chiri pazasi chaipo pechimiro. Pfungwa apa haisi mune mamwe maitiro ayo (ayo anozokurukurwa gare gare), asi muchokwadi chekuti radiation sosi iri pamusoro pepasi (tinogona kungoona mumvuri "mahwindo" epasi, facade uye madziro emadziro). Zvakare, iyo woofer inosiiwa nekambani kubva pasi kusvika pakakwirira, iyo curve inofanana neanozivikanwa anonzi. isophonic curves, asi izvi hazviteveri kubva kune (zvakare) mhedziso yakapfava yekuti tinofanira "kururamisa" zvimiro zvekunzwa kwedu nenzira iyi (iyo yatisingagadzirise nechero zviyamuro zvekunzwa kana tichiteerera manzwi echisikigo uye mimhanzi inorarama). Kudiwa kwekururamisa uku Chario kunobva mumamiriro akasiyana-siyana atinoteerera mimhanzi - kurarama uye kumba, kubva kune vaviri vatauri. Kana tichiteerera mhenyu, masaisai akananga uye anoratidzwa anosvika kwatiri, ayo pamwe chete anogadzira chitarisiko chechisikigo. Kunewo zvinoratidzira muimba yekuteerera, asi zvinokuvadza (uye naizvozvo Chario anodzideredza achishandisa nzira dzakatsanangurwa pamusoro apa), nokuti. gadzira zvakasiyana zvachose mhedzisiro, kwete kuburitsazve acoustic mamiriro ekurekodha zvachose, asi zvichikonzerwa neacoustic mamiriro eimba yekuteerera. Mamiriro enzvimbo yepakutanga yekurekodha akakodhewa muruzha rwunoridzwa nepamagudzanzwi mumasaisai akatwasuka (eg reverberation). Nehurombo, vanouya chete kubva kudivi remagudzanzwi, uye kunyangwe machinjiro echikamu anogona kuwedzera nekudzika nzvimbo yedu haazogadzirise zvachose mamiriro acho. Maererano netsvagiridzo yaChario, maonero edu anonyanya kutarisisa mafrequency epakati, izvo zvinoda kudzikiswa kusvika pamwero wakati kuti tiwane hunhu hwakanyanya hunobvira hwechiitiko chenzwi rose, mune zvese matauriro uye nzvimbo.

Kana mumwe achidhonza, mumwe anosundidzira

Dhizaini yeSerendipity subwoofer chikamu chitsauko pachayo. Pano takatarisana nepush-pull system, isingawanzo shandiswa nhasi (neimwe pfungwa yakakura, inonziwo komputa kana isobaric). Aya mawoofer akabatana nemichini "diaphragm kune diaphragm" uye zvemagetsi nenzira yekuti madiaphragms adzo anofamba nenzira imwechete (inoenderana nemuviri, kwete mabhasikiti ega). Naizvozvo, masimba aya haamanikidzi mhepo yakavharwa pakati pavo (saka zita rokuti isobaric), asi rifambise. Kuti uite izvi, kana vaine chimiro chakafanana uye matende akakuvadzwa munzira imwechete, anofanirwa kunge akabatana akapesana (kune mumwe nemumwe) polarities (nekumaka magumo avo) kuitira kuti vazopedzisira vashanda muchikamu chimwe chete (apo. iyo coil yakadzika imwe) mumagnetic system, coil yeimwe inobuda). Saka zita rekuti push-dhonza - kana mumwe mutauri "adhonza", mumwe "anosundidzira", asi ivo vachiri kushanda nenzira imwechete. Imwe mutsauko pane iyi gadziriro ndeye magineti-ku-magineti kurongeka, uye imwe inoshanda neyakafanana sonic mhedzisiro ndiyo gadziriro apo vatauri vanoiswa mumwe kuseri kweimwe kwakatarisana (magineti ekunze akatarisana negineti). buri remukati). Ipapo vatauri vanofanirwa kubatanidzwa mune imwechete polarity - yakadaro sisitimu, kunyangwe ichiri "isobaric", haifanirwe kunzi push-pull, asi, pamwe, komputa.

Ini ndichanyora nezve misiyano midiki pakati pezvisarudzo izvi pakupedzisira, asi chii chinonyanya kukosha chegadziriro ino? Pakutanga kuona, iyi gadziriro inogona kuita sekuwedzera kumanikidza kunoitwa nevatauri vese. Asi kwete zvachose - hongu, sisitimu yakadaro ine simba rakapetwa kaviri (inotorwa nemakoiri maviri, kwete imwe), asi iri hafu inoshanda (yechipiri "chikamu" chesimba chinopihwa kune yechipiri chitaurisa hachiwedzere kumanikidza) . Saka nei tichida mhinduro isina simba yakadaro? Kushandiswa kwevatyairi vaviri mupush-pull (composite, isobaric) system inogadzira mhando yemutyairi mumwechete ane ma parameter akasiyana. Tichifunga kuti ine maviri akafanana transducers, Vas ichave nehafu uye fs haizowedzeri, nekuti isu tine zvakapetwa kaviri zvekuzunguza misa; Qts haina kuwedzera kana, nekuti isu tine kaviri "drive". Summa summarum, kushandiswa kwepush-kudhonza kunokubvumira kuti uwedzere kaviri huwandu hwekabati (mazhinji masisitimu - anosanganisira akavharwa, bass-reflex, bandpass, asi kwete mitsara yekufambisa kana nyanga kabati) kuti uwane humwe hunhu, uchienzaniswa nekushandisa gudzanzwi rimwechete (o maparamita mamwe chete, seane magudzanzwi maviri).

Nekuda kweizvi, neisina vhoriyamu yakakura kwazvo (ndinokuyeuchidza kuti iyo yepamusoro module inoshumira zvimwe zvikamu), takawana yakaderera cutoff frequency (-6 dB pa20 Hz).
