Munhu ari kushanda zvishoma

Kambani yeCanada Paradigm ndeimwe yevagadziri vezvitaurisa zvikuru munyika. Mipiro yaro inotangira kubva kumabhajeti emhando kusvika kune yepamusoro-yekupedzisira supercars kubva kune referensi Persona akateedzana. Pamusoro payo pane Persona 9H modhi, kwete yakakura chete, asiwo yakasarudzika ne "hybrid" yayo, ine chikamu inoshanda system.

Zvigadziridzo zvinoshanda zvishoma (nechikamu chinoshingaira chepasi-frequency) hazvisi zvishoma zvokuti "Vanhu" vanogona kuonekwa sebasa rekutsvaga uye rakasiyana. Nekudaro, Paradigm yakawedzera zvimwe zvishoma kwavari izvo zvinovaita vepakutanga uye vepamberi. Iyo inonyanya kukosha tekinoroji yakajairika denominator yezvese Persona magadzirirwo, uye chimiro chinovabvumira kupenya kunyangwe padivi pevakwikwidzi vakasimba, ndiko kushandiswa kweberyllium - kwete chete mutweeter, iyo inopararira zvishoma nezvishoma, asiwo pakati (mumatatu). -nzira shanduro) uye midwoofers (mune nzira mbiri - Personie B rack gomo).

Chete uye parizvino…inoshanda zvishoma

Iyo chete Persona 9H ndiyo "hybrid", inosanganisa inoshanda yakaderera-frequency chikamu ine classically passive (passive-filtered) yepakati-yepamusoro chikamu. Chiitiko cheiyo yakaderera-frequency chikamu hachizi chete mune akavakirwa-mukati amplifiers ane paramita, kusanganisira hunhu hwekutamisa, hunogadziriswa kune vatauri zvinoenderana nerenji dzavanofanira kushanda, asiwo mukudyidzana navo DSP processors, izvo zvinokutendera kuti uchinje zvakasununguka izvi paramita. hunhu sekurairwa neiyo yekururamisa system (maererano nekamuri acoustics). ) ARC. Iyi inogara yakagadziridzwa sisitimu, iyo inoshandiswa neakawanda uye akawanda madivayiri emhando yezvine hanya - Paradigma, Anthema, Martin Logan.

Pane USB yekuisa pane yekumashure, uye maikorofoni ne USB tambo zvinosanganisirwa. Zvisinei, hatizvibatanidza zvakananga kumutauri. Iwe unozodawo komputa ine kanenge kaviri USB ekuisa, iyo yatinobatanidza zvese mutauri uye maikorofoni. Isu tinodhawunirodha chirongwa cheARC kubva kunetiweki nebasa - isu tinoona hunhu hunoonekwa munzvimbo yekuteerera (neyakaipoteredza), uye sisitimu inoaongorora uye inopa mazano ekugadzirisa. Tinogona kuzvigamuchira kana kuzvishandura, kana kuisa chero hunhu nemaoko.

Isu tinoita nzira iyi zvakasiyana kune imwe neimwe column. Mushure mekusimbiswa, iko kururamisa kunochengetwa neDSP mukoramu pachayo, uye bhatani riri panhivi yekumashure rinoibatidza nekudzima sezvaunoda. Kuenzana kunoshanda chete mune yakaderera-frequency renji, iyo inokonzerwa zvese nekugumira kwesoftware pachayo (kunyangwe shanduro dzichangoburwa, maererano nevanogamuchira Anthema, dzatoshanda muhuwandu hwese), uye nekugadzirwa kwePersona 9H - iyo sisitimu inogona kushanda chete kuburikidza neDSP uye yakavakirwa-mukati amplifiers, uye saka chete muchikamu chinoshanda.

Chete dhizaini yegudzanzwi inoshanda zvizere inobvumira kuenzana pamusoro peiyo frequency renji. Zvisinei, usazvidya mwoyo pamusoro peizvi, sezvo matambudziko makuru ane resonances anowedzera mu-low-frequency range, uye panguva imwechete, nekugadzirisa kwakadaro, zvinogadziriswa nyore nyore.

Iyo ARC system ndeyekusarudza muVanhu 9F. Nekudaro, isu tinogona kutanga vatauri tisinganetseke nazvo zvachose - tobva tangovabatanidza kunetiweki (iyo bass chikamu chinofanirwa kugara chichishanda), kune yekunze amplifier ine acoustic tambo (hapana mutsara wekupinda) uye ita. kusagadzirisa chero chinhu. .Kuti. maitiro makuru echikamu chepasi-frequency chikamu, uye naizvozvo chivharo chose, "chakaoma" chakagadziriswa.

Kwete maviri, asi mana...

Iyo Persona 9H yakaenzana saizi neiyo yakachipa uye inongoita chete Persona 7F. Iwo madhizaini anosiyana, zvisinei, kwete chete pamberi pe processors uye amplifiers mumureza. Kumberi, semuMunhu 7F, tinoona maviri 20cm woofer. Izvi zvakawanda uye zvishoma ... Kana kuti pamwe hurongwa hunoshanda, huchikubvumira kuti uishandise zvakakwana, hunopa zviri nani "kuita" zvose maererano nechepasi cutoff frequency uye yakanyanya kudzvinyirira chiyero, kana chimwe chezviyero izvi?

Mawoofer mana anoshanda mukamuri imwe yakavharwa - kudzvanywa kubva kune maviri ari "kuseri" uye akavanzika mukati anopfuura nepanzvimbo dzealuminium pani kumashure (amplifiers akaiswawo ipapo). Nekuda kwekugadziriswa kwakaunzwa (kurongeka kwehunhu kune yakagamuchirwa yakaderera yekumisikidza frequency), iyo inoshanda sisitimu inobvumira kushandisa ine mwero vhoriyamu kune yakadaro bhatiri yevashanduri, uye kuisirwa kwavo kunobatsira kuderedza kushushikana mune iyo kesi. Ane simba magineti masisitimu "anonzvenga" mumwe nemumwe kuti akwane zvese izvi arsenal mune yakagadziriswa yakadzika kesi.

Iyo inogoneka uye yakagadziriswa kururamisa yakanyatso kuderera cutoff frequency, asi inoreva "kushandiswa" kwakasimba (kushanda nemaswings makuru) ewoofers mune iyo iyo hunhu "yakadhonzwa". Ichokwadi, iyo yakawedzera subsonic kusefa inomisa iyi nhamburiko, asi iri pasi pe20 Hz, uye iyo yakavharwa kesi inoshandiswa haina pfuma ye "kuchengetedza" iyo woofer kubva kune yakakura amplitudes mune yakasarudzwa frequency renji (pa uye padyo ne frequency). kesi resonant frequency).

Asi kusarudzwa kwekabhati yakavharwa yePersona 9H, iyo nzira inopa mhinduro yakanakisisa yekukurudzira, inouya neimwe chidimbu chemashoko akanaka-kwete maviri, asi mawoofer mana akaiswa mukugadzirwa uku. Saka manje! Zviviri hazvionekwe kubva kunze, asi hazvishande mune imwe komputa, kusunda-kudhonza system, asi nenzira yakananga; iyo wave kubva kumberi mativi e membranes avo inopfuura neyakavhurika aluminium grilles inovhara kumashure / kuzasi kwekesi. Iyo (isina-yakavharirwa) nzvimbo yakagadzirwa nenzira iyi yakashongedzerwa nemagetsi, ayo anotora mukana wekugona kutonhora.

Mukududzirwa kwakapfava kwechirongwa chemukurukuri chinoshandiswa, mana 20 cm woofers anoshanda mukamuri yakavharwa yakajairwa, muchikamu chimwe - kunyanya, sekunge iwo ese akaiswa pamadziro akafanana, semuenzaniso, pane yepamberi. Pasinei nechinzvimbo chegudzanzwi, mafungu akareba emhepo yakaderera anopararira kumativi ose, sezvatave tatsanangura kanopfuura kamwe, uye magudzanzwi anopenya "kumashure" haashande mu antiphase neaya anopenya "mberi"; zvakakosha kuti vese vadzvanyirire uye vawedzere mhepo panguva imwe chete.

Kuiswa kusingajairike uye kuvanza kwevamwe vatauri hakuna kurairwa neimwe exotic acoustic pfungwa, asi nezvimwe zvinhu zviri nyore kuziva. Ichokwadi kuti ese mana 20cm madhiraivha anogona kuramba achikwana pane yekumberi pasina kuita kuti kesi yacho ive yakakura, asi pane mechanic mukana wekuvaisa kumberi nekumashure; ese anoshanda muchikamu, asi mauto anoshanda pane anotsigira chimiro (casing) anotungamirwa kune yakatarisana - saka ivo vanobhadharwa zvakanyanya uye casing "haifambi".

Side-ne-side woofer kuiswa kwakajairika mune inoshanda subwoofers, iyo Paradigma inopa muhuwandu, saka vagadziri vanogona kutora kurudziro kubva kwavari. MuMunhu 9H, vatauri havamire zvakapesana, asi "vanopfuura nepakati" magineti masisitimu ane simba uye akadzika zvekuti dai zvisina kudaro aisazokwana mukanzuru iyi.

Uye iyo kesi, ye20 7s, haina kumbokura, saka iwe unogona kubvunza kana ... haina kunyanyo diki kuti uvagadzirire yakanyanya kunaka mamiriro ekushanda, sezvo mune yakafanana vhoriyamu ye9F modhi (kana kunyange yakakura zvishoma - ine nzvimbo yakaparadzana ) mu20H yemaamplifiers) maviri chete XNUMX cm LFs anoshanda? Apa ndipo apo kugona kweiyo inoshanda sisitimu uye yakavharwa muviri inodzoka uye inopindirana.

Imba yakadaro, kuitira kuti iwane mhinduro yakakwana, iyo inowanzo tsanangura zviyero zveimba kune mugadziri, haidi vhoriyamu yakakura kudaro (tichifunga nezvegudzanzwi rimwechete rine paramita yakatarwa) sebass reflex imba. Saka zvinogona kunzi zvakarurama kuisa akawanda se20 7s mune yakavharwa system mune yakafanana vhoriyamu, umo maviri e20s mune bass reflex (Persona XNUMXF) inoshanda zvakanaka - izvo zvinounza kuwedzera kwesimba uye kugona, asi. ine yakakwira cutoff frequency (yakaderera yakawedzera hunhu).

Maererano nemugadziri uye zviyero zvedu, kutambanudza kwakanaka kwazvo (-6 dB pa 15 Hz!), Zviri nani kudarika muMunhu 7F, uye iyi ndiyo mhedzisiro yekugadziriswa kwehurongwa. Nokudaro, mhinduro yakaoma uye inyanzvi - muviri une zviyero zvakafanana nePersona 7F ine simba rakawanda, riri nani mune zvose uye "kuzvimiririra" chikamu chepasi-frequency, pamwe nekuwedzera kweARC.

… Woofers

Iwo woofers akasiyana zvachose. Paradigm yakatochinja mhasuru dzayo mumakwikwi aya, ichidzidza chikamu cheiyo subwoofer dhizaini. Iyo dhiraivha sisitimu yakapetwa kaviri - iyo diaphragm inopfuudzwa nemakoiri maviri akakuvadzwa imwe mushure meimwe (uye kwete imwe pamusoro peimwe) pane refu refu furemu. Iyo magineti system ine maviri slots (yakazvimiririra kune ese macoil), iyo inogadzira yakanyanya symmetrical chimiro chedhiraivha yese.

Kutenda kune iyi mhinduro, kukanganisa kunokonzerwa ne "natural" asymmetry mukugadzira uye kushanda kweakajairika converter kunobviswa. Coil imwe chete, iyo inoyerera ikozvino, inova sosi yekuwedzera shanduko yemagineti, iyo inovhiringidza iyo magineti inogadzirwa mugedhi neanogara magineti yegudzanzwi. Makoiri maviri akaiswa "akatarisana" anogadzira magineti minda yekusingaperi yakatarisana polarity, kuitira kuti pesvedzero yavo pamunda wenguva dzose irege kuderedzwa; iyo inductance yemakoiri inodererawo, izvo zvinokonzeresa kukanganisa.

Makoiri maviri akareba anogona kutora mutoro mukuru wekupisa, sezvizvi zvinofanirwa kuteverwa neyakafanana yakasimba magineti system, zvakare "nzombe". Makoiri, kana kuti iyo refu furemu yavakakuvadzwa, inotungamirwa nezvitubu zviviri zvakanamirwa padyo nemapendero ayo kuti ive nechokwadi chekufamba kwayo kweaxial mumigero iri kure. Nokudaro, tswanda yechipiri inooneka kuseri kwemagnetic system, iyo iyo yechipiri chitubu chinozorora. Kwese kwese kwaunogona kuona kugadzirira kwekushanda nemaamplitudes makuru, kusununguka kusunungurwa kwekumanikidzwa uye mhepo kubva pasi pezvikamu zvose zvinofamba. Dengu iri pachena rakakandwa kubva kusimbi yakareruka, uye kuomarara kwayo kunoramba kwakakosha neiyo inorema magineti system uye nehutsinye hwekushanda kweiyo coil.

Iyo diaphragm inogadzirwa neanodized aluminium, yave ichishandiswa kwemakore (fomu yekambani ndeye X-PAL). Iine chimiro che "ndiro" yakasimba, ine kumiswa kwepamusoro ine inverted profile, yakasimbiswa nekukora (kupfupikiswa kwechiratidzo cheART). Iyo woofer diaphragm pachayo haisi sandwich yekutanga. Pano, kunyange imwe chidimbu chealuminium chinogona kuita basa rayo zvakakwana, chero bedzi isiri yakaonda, iyo vamwe vanoedza kuderedza uremu, kunyange ... )

Enda kubva ku beryl kuenda ku beryl

Mutyairi we midrange yakakura kwazvo, tichifunga nezvehupamhi hwebhasiketi - 18-pole. Kuonekwa kweberyllium diaphragm mu midwoofer, kana kunyange midwoofer (Persona B), inobudirira zvikuru, kunyanya sezvo Paradigm inosimbisa kuti teknolojia inoshandiswa pano ndiyo yakanakisisa uye "iyo chete chaiyo" inogona kuzvirumbidza "yakachena" beryllium. diaphragms.

Kuchena hakusati kwasvika 99,9%, nekuti kune kumwe kusvibiswa musimbi yega yega, asi XNUMX% mhedzisiro inotsanangura zvizere kuti isu tiri kubata nemamembrane akaumbwa kubva kuberyllium foil, uye kwete nekusvipa beryllium pane zvakasiyana zvachose. Paradigm inowanzopa zita rekuti Truextent, zvichireva tekinoroji inoshandiswa, asi munyori uye muridzi wayo ikambani yeAmerica Materion, inopa iyi foil uye kunyange yakagadzirira-yakagadzirwa beryllium membranes kune ese Paradigm uye mamwe anozivikanwa mabhureki (zvakare Focal, Scan- Taura uye Magico).

Saka kana iwe uchida kuverenga nezve zvimiro zveberyllium, semashandisirwo azvinoita mumagudzanzwi, bheji yako yakanaka kuenda kuwww.materion.com.

Mutsara mumwe unotsanangura zvakanakira beryllium pamusoro pemamwe masimbi anoshandiswa mu membranes, kunyanya aruminiyamu yakakurumbira uye titanium isingawanzo zivikanwa. Panzvimbo pekuomarara, izvo zvisiri pachena zvinodikanwa kuti ubudirire kune tweeter (kune zvinonzwika zvakapfava-muviri - sirika domes), uremu uye mukati damping, zvinyorwa zvinotaura kumhanya kwekuparadzira inzwi mune izvi zvinhu.

Kune beryllium, iyi kukurumidza inosvika 2,5 nguva yakakwirira, iyo inoratidzwa zvakananga mukuti mune diaphragm yeimwe dhayamita, iyo yekuparadzana mhedzisiro ichashandurwa ka2,5 kuenda kune yakakwirira mafrequency. Zvinoenderana nekuverenga uku, kana akajairwa 25mm aruminiyamu domes achirira angaita 20kHz, ipapo beryllium "inongorira" panosvika 50kHz. Musoro wemusoro ungaratidzika kunge wakakura zvisina kufanira, asi resonance iyi inowanzotungamirwa nekudonha kwekuita uye shanduko yechikamu, iyo inofanirawo kutorwa kunze kweiyo acoustic range. Tinogona kutaura kuti kushandiswa kweberyllium mumutyairi we midrange hakuunze kuvandudzwa kwakadai mumamiriro ezvinhu, nokuti kuparadzaniswa kwekuparadzana hakuna kunyanya kukosha kana uchishandisa sefa yepasi-pasi.

Nekudaro, zvinogara zvirinani kuibvisa kubva kune yaitarisirwa kuita segudzanzwi renji, uye Paradigm inonongedza chimwe chinhu - zvakafanana diaphragm zvinhu zviri pakati nepakati uye tweeters inovimbisa kuwirirana kwezwi uye kuenderana kwemavara. Kunze ... iyi haisi nharo iyo vese vanogadzira vangafunga yakakosha, kazhinji vachishandisa zvakasiyana membrane zvinhu mumhando dzakasiyana dzema frequency, vachichinjika kuzvigadzirisa kune zvakati zvinodiwa.

Ose ane beryllium diaphragms, MF neHF, akafukidzwa nehunhu hwemakwakwakwa esimbi. Mugadziri anovapa yakakosha acoustic basa - ndosaka achivapa rakasiyana zita rekambani uye chidimbu: PPA, kana Perforated Phase Aligning. Izvo zvakagadzirirwa "kuvhara kunze-kwe-phase frequencies".

Nekudaro, munhu anogona kufungidzira kuti chinangwa chikuru ndechekudzivirira yakapfava uye inodhura beryllium membranes kubva mukukuvadzwa, iyo yakasarudzwa kuburitsa nenzira yepakutanga kupfuura yakajairwa "mesh," ichitigadzirira imwezve yekuona kukwezva, uye nekuwedzera, kupa maacoustics "yakadzika chirevo." Izvi zvinogona kunge zvakavandudza hunhu hwepakati-frequency (dzinenge dzakanyatso mutsara), kunyangwe paine kusimuka kwakasimba kweiyo tweeter renji (kutenderera 10 kHz) uye unotofanira kubvisa chivharo ichi kuti uone kuti ndiko kwakabva here kana kuti mutauri pachake.

Glossy yemazuva ano Muviri mukuru wemuviri wakagadzirwa neMDF uye HDF mabhodhi; mativi akakomberedzwa "akadhindwa" kubva pazvikamu zvinomwe zvitete zveHDF zvakanamwa chete pamuchina. Kunze, yakawanda yealuminium yakawedzerwa. Inenge chikamu chese chepamberi chakasimbiswa nacho, chikamu chekumashure chemuviri chakafukidzwa nealuminium openwork profiles, uye yakakura, yakawanda-element plinth (yakabatana kune hwaro hwekubatanidza terminal) inogadzirwawo nealuminium.

Chimiro chayo chakanangana nekugadzirwa kwemamwe mamodheru-akamira, uko bass-reflex tunnel yakapfuura nepakati peplate - saka "kusimudza" kwepasi kwekabati kuenda kumashure, ichigadzira nzvimbo yekuti yemahara wave kubuda. . . Nekudaro, iyo Persona 9H chivakwa chakavharwa uye "hapana chinoitika" pakati pechigadziko nebhokisi.

Muviri wakaputirwa ne-high-gloss varnish - hapana mavhezheni esarudzo, ayo anoratidzawo kusimuka kwakasimba kubva ku "fenicha" tsika mune ino nhevedzano. Kune akawanda emavara emhando, mashanu akajairwa, uye gumi akakosha, Premium. Uye zvakare, iwe unogona kusarudza ruvara rwezvinhu zvesimbi - iyo base, pamberi pepaneru, kumashure kwezvivharo zvemba, woofers uye maballast e "acoustic lenses" yepakati uye tweeter - anodized muruvara rwearuminiyamu yechisikigo kana dema.
