Kodi Zipangizo Zamakono Zimapanga Kusiyana Kwambiri? Sayansi Imayendera Mu!

Zotsatira Zomwe Mungakudabwe nazo

Zingwe zamalankhula ndi zotsatira zawo pa audio zingakhale nkhani yotsutsana kwambiri yomwe imawombera mobwerezabwereza. Pofotokoza mayesero a ma foni kwa Allan Devantier, mtsogoleri wa kafukufuku wamakono ku Harman International (opanga mauthenga a Harman Kardon , JBL ndi oyankhula bwino , ndi zina zambiri zamakalata), takhala tikukambirana mozama. Kodi zingatheke kuwonetsa pogwiritsa ntchito luso loti - pazifukwa zovuta kwambiri - zipangizo zoyankhulirana zingapangitse kusiyana kwakukulu kwakumveka kwa dongosolo lanu?

Zina Zamalamulo

Choyamba, chotsutsa: tilibe lingaliro lolimba pa zingwe za oyankhula. Tachita zozama zamakhungu (makanema a Home Theatre ) omwe akatswiri otsogolera anayamba kupanga zokhazokha zazingwe za ena. Komabe sitimadzifunsa kawirikawiri.

Anthu ena amatha kukhumudwa ndi mbali zonse za wokamba nkhani. Pali mabuku omwe amatsutsa mwatsatanetsatane kuti makamba oyankhula samapanga kusiyana kulikonse. Ndipo kumbali inayo, mungapeze ena olemba maphunzilo apamwamba omwe amatha nthawi yaitali, omveka bwino, owonetsa bwino kusiyana kwa "phokoso" la zingwe zoyankhula. Zikuwoneka kuti ambiri akulimbana ndi maudindo m'malo mochita khama lofunafuna choonadi.

Mukangoganizira, izi ndizo zomwe timagwiritsa ntchito payekha: zingwe zina zomwe zimapangidwa ndi Canare, zipangizo zamakono 14, zingwe zoyendetsa maulendo angapo, ndi zingapo zingapo zokhala pansi.

Tiyenera kuwonjezera kuti m'zaka zoposa 20 akukamba nkhani, ndikuyesera okamba ochokera pansi pa US $ 50 kufika pa $ 20,000 pawiri, ife takhalapo ndi mmodzi yemwe akupanga chidwi chake pazinthu zomwe akugwiritsa ntchito.

Allan's Analysis

Chomwe Devantier anali nacho chidwi chinali pamene tinayamba kuyankhula za momwe wolankhulira chingwe angagwiritsire ntchito, mwachindunji, kusintha mwayankhidwe wafupipafupi wa wokamba nkhani.

Wokamba nkhani aliyense makamaka ndi fyuluta yamagetsi - kuphatikiza, kukakamiza, ndi kukakamiza kugwiritsidwa ntchito (chiyembekezo chimodzi) kuti apereke khalidwe labwino kwambiri. Ngati muwonjezera kukanika , kukakamiza , kapena kutengeka , mumasintha malingaliro a fyuluta, motero, phokoso la wokamba nkhani.

Wokamba nkhani wamba chingwe alibe kapangidwe kakang'ono kapena kapangidwe kake. Koma kukana kumasiyana mosiyana, makamaka ndi zingwe zoonda. Chifukwa ndi zinthu zina zonse zikufanana; Kuchepetsa waya, kumakhala kovuta kwambiri.

Devantier anapitirizabe kukambirana pofufuza kafukufuku wochokera kwa Floyd Toole ndi Sean Olive, ogwira nawo ntchito ku Harman, omwe anali panthawi yomwe akugwira ntchito ku National Research Council ku Canada:

"M'chaka cha 1986, Floyd Toole ndi Sean Olive adafalitsa kafukufuku wokhudzana ndi kuwonetserana kwapadera kwapadera. Anapeza kuti omvetsera amamvera kwambiri zivomezi zochepa za Q-mkulu. Popeza mpikisano wamakono akusiyana ndi maulendo ambiri, kutsutsana kwa DC kumakhala kofunika kwambiri. Tsatanetsatane yotsatilayi ikuwonetsera kutalika kwa utali wamtundu wotetezera kuti zitsimikizo za kusiyana kwapadera zomwe zimayambitsidwa ndi chingwe zikhale pansi pa 0.3 dB. 4 ohms ndi mpweya wochuluka wa omasuka wa 40 ohms ndi kuti kukwera kwa chingwe ndi chinthu chokhacho, osati kuphatikizapo chinyengo ndi kapangidwe ka zinthu, zomwe zingangopangitse zinthu kukhala zosayembekezereka. "

"Ziyenera kukhala zomveka kuchokera pa tebulo ili kuti panthawi zina chingwe ndi loupipu zingagwirane ntchito kuti zitheke."

Zoyeza za Brent

"Mukudziwa, mungathe kuyeza izi," anatero Allan, akulozera chala chake m'njira yomwe imatanthauza lamulo koposa lingaliro.

Takhala tikuyang'ana mafupipafupi pazokambirana kuyambira 1997, koma nthawi zonse tangogwiritsa ntchito kachipangizo kabwino, wamkulu, mafuta wothandizira kuti alumikize wokamba nkhani poyesedwa kwa amp - chinachake chomwe sichidzakhudza kulondola kwa muyeso.

Koma bwanji ngati ife titalowetsamo crummy, otchipa ochepa otchulidwa chingwe? Kodi kusiyana kungayesedwe? Ndipo kodi izo zikanakhala mtundu wa kusiyana umene ukanamvekanso?

Kuti tidziwe, tinayesa kuyankha kwafupipafupi kwa Wotchuka wa Revel F208 wothamanga pogwiritsa ntchito katswiri wa audio wa Clio 10 FW ndi zingwe zitatu zosiyana:

1. la Linn cable yomwe takhala tikugwiritsira ntchito poyesa wokamba nkhani zaka zisanu kapena zisanu zapitazi
2. chingwe chotsika mtengo cha Monoprice 12
3. chingwe cha RCA chosachepera 24

Kuchepetsa phokoso la chilengedwe, miyeso inkachitidwa m'nyumba. Mayikolofoni kapena wolankhula kapena china chirichonse mu chipindacho chinasunthidwa. Tinagwiritsa ntchito chingwe chowonjezera cha Moto kuti kompyuta ndi anthu onse zikhale kunja kwa chipinda. Tinayambiranso mayesero kawiri kawiri kuti tiwone kuti phokoso la chilengedwe silinakhudze kwambiri mayeso. Bwanji osamala? Chifukwa tinadziwa kuti tikhoza kuyesa kusiyana kwachinsinsi - ngati chirichonse chikhoza kuwerengedwa nkomwe.

Kenako tinayankha ndi Linn cable ndipo tinagawanika ndi kuyankhidwa kwa zingwe Monoprice ndi RCA. Izi zinayambitsa graph yomwe inasonyeza kusiyana kwa kayendedwe kafupipafupi kotengedwa ndi waya. Kenaka tinagwiritsa ntchito 1/3-octave kuwunikira pofuna kuthandizira kuti pakhale phokoso lokhalitsa lachinyama.

Zikuoneka kuti Devantier anali wolondola - tikhoza kuyeza izi. Monga momwe mukuonera pa chithunzicho, zotsatira ndi zingwe ziwiri za gauge zinali zosiyana kwambiri. Kusintha kwakukulu kunawonjezereka kwambiri pa00.4 dB pakati pa 4.3 ndi 6.8 kHz.

Kodi izi zikumveka? Mwina. Kodi mungakonde? Mwinamwake ayi. Kuti tiwone bwinobwino, ndizokafika pa 20 mpaka 30 peresenti ya kusintha kumeneku kumayesa pamene tayesa wokamba nkhaniyo komanso popanda grille .

Koma kusintha kwa chingwe cha 24chi chinakhudza kwambiri. Poyambira, yachepetsa msinkhu, ndipo imafuna kuti normalization ya mayendedwe a mayendedwe awonjezereke powonjezerapo +2.04 dB kotero kuti ikhoza kufanizidwa ndi makina a Linn cable. Kuthamanga kwa makina 24 omwe akutsutsana nawo kunakhalanso ndi zotsatira zoonekeratu pa kuyankhidwa kwafupipafupi. Mwachitsanzo, amadula pakatikati pa 50 ndi 230 Hz pofika pa -1.5 dB pa 95 Hz, kudula pakati pa 2.2 ndi 4.7 kHz ndipakati pa -1.7 dB pa 3.1 kHz, ndi kuchepetsedwa pakati pa 6 ndi 20 kHz ndi -1.4 dB pa 13.3 kHz.

Kodi izi zikumveka? Eya. Kodi mungakonde? Eya. Kodi mungafune kuti phokosolo likhale bwinoko ndi chingwe choyera kapena imodzi mwa mafuta? Ife sitikudziwa. Mosasamala kanthu, ndondomeko zowonjezeredwa za stereo zogwiritsira ntchito zingwe 12 kapena 14 zayeso zikuwoneka bwino kwambiri.

Ichi ndi chitsanzo choopsa kwambiri. Ngakhale kuti pangakhale zingapo zing'onozing'ono zowonongeka zitsulo kunja uko, pafupifupi zingwe zonse zoyankhula zomwe zili ndi-14-gauge kapena zimakhala zochepa zomwe zimakhala zochepa kwambiri (ndipo mwina n'zosatheka). Koma ndizofunikira kuzindikira kuti tinayesa kusiyana kosiyana ndi kubwerezabwereza, ngakhale ndi zingwe ziwiri pafupi ndi kukula kwake. Komanso, onani kuti Revel F208 wokamba nkhani ali ndi mpweya wabwino wa 5 ohms (monga momwe anayezera). Zotsatirazi zikanakhala zovomerezeka kwambiri ndi wolankhula 4-ohm ndi zochepa zomwe zimatchulidwa ndi oyankhula 8-ohm, omwe ali ndi mitundu yofala kwambiri.

Kotero ndi phunziro lanji kuti muchotse ku izi? Kwenikweni, musagwiritse ntchito zingwe zachitsulo m'dongosolo lililonse lomwe mumasamala za khalidwe labwino . Komanso, mwamsanga musaweruze omwe akunena kuti amamva kusiyana pakati pa zipangizo zoyankhula. Zowonadi, ambiri a iwo akuwongolera zotsatirazi - ndipo malonda ochokera kumtunda wapamwamba makampani nthawi zambiri amawongolera zotsatirazi. Koma ziwerengero ndi zoyesera zomwe zachitika zimasonyeza kuti anthu akumva kusiyana pakati pa zingwe .
