Waa maxay impedance ee headphones ah

headphones Impedance - taasi waa ay iska caabin ah si ay u soo galo. Ku xiran tahay waxa, sifooyinka badan oo farsamada iyo hawl iyaga ka mid ah oo ku saabsan.

Haddii impedance hoose ee headphones ah (25 ohms ama ka yar), ay u baahan yihiin tamar ka yar si ay u bixiyaan dhawaaq oo tayo sare ah. headphones Kuwan waxaa si wanaagsan aduu isticmaalka qalabka sida ciyaartoyda music, telefoonada gacanta iyo aaladaha kale ee la qaadi karo.

Oo haddii impedance ka headphones waa 25 ohms dheeraad ah, ay u baahan yihiin tamar badan si heer sare ah wax soo saarka. caabin Tani waxay ka ilaaliya dhaawaca suurto gal ka dhigay by overloads. headphones waxaa loo isticmaali karaa oo leh qalabka audiotehnicheskih kala duwan. Tusaale ahaan, waxaa ka mid ah, kuwaas oo loo isticmaalo in lagu DJ-brandingeksperten model, iska caabin magacaaban taas oo ku saabsan 25-70 ohms.

Haddii impedance headphone gaaban tahay, ay u noqdaan kuwo ka badan oo u nugul dhaawac marka la isticmaalayo a Sammeecado-awood sare. Haddii aad, tusaale ahaan, ku xidhi headphones la impedance hooseeyo goob dj-ta ah iyo u isticmaali doonaa si ay awood buuxda, waxaad leedahay iyaga, malaha qarxi.

Sidaas daraaddeed, waa maxay impedance si mug leh? Sameecadaha dhegaha la isticmaalo ciyaaryahan audio proslushavaniya ama laptop la qaadan karo, in si horseednimo leeyihiin iska caabin ah oo ku saabsan 16-20 ohms iyo dareenka ugu yaraan 100 dB / mw. Haddii qalab aad la kulmo heerarka Yurub ee mugga ugu badan, waxaa fiican inaad doorato headphones la impedance ah 16 ohms, tan iyo qalabka xoog badnaan waa weli ka yar ee kuwa kale.

Sida caadiga ah, lagu taliyey impedance magacaaban headphones tilmaamay in waraaqo ah ee qalabka.

Waxaa muhiim ah in ay tixgeliyaan impedance ee headphones ah, sida lagu daydo oo dhan ma inay la xaddi kala duwan ee awoodda korontada iyo iska caabin shaqeeyaan. model headphone kasta oo si gaar ah loo xisaabiyaa iyo dhexdiisa si ay ula kulmaan mugga gaar ah load. Tani ma aha oo kaliya ay hubisaa in ammaanka isticmaalka technology, laakiin sidoo kale cimrigay dheeraysaa ay cimri.

Horaantii, ee 60-80 sano, inta badan isticmaalaan headphones impedance sare, tan iyo qalabka wax soo saarka tamarta in wakhtigaagu wuxuu ahaa mid aad u sarreeya ka. Marka bilaabay resistors isticmaalo, hoos danab wax soo saarka. In 1996, waxa uu dhigay heerka on impedance headphone ah - 120 Ohm. Arrintan ayaa saameyn weyn ku soo saarka iyo horumarinta lagu daydo la impedance sare, laakiin waqti isku mid ah ka hor joogsateen horumarinta dheeraad ah jiho kale. In 2009, iibka weyn ee iPod ah, taasoo keentay in qalabka la iska caabin yar yahay ayaa helay taageero sare. Sidaa darteed, horumarinta headphones la impedance hoose, helay wadadii cusub.

Sidaas darteed, impedance oo ka mid ah - mid ka mid ah, haddii aan wax badan u, laakiin weli sifooyinka muhiimka ah ee headphones ah. Waxaan ka dooro aad model waa in la raaci qalabka audio, aad isticmaalayso, tayada codka ugu badan iyo in la hubiyo hawlgal caadi ah oo xasilloon. Sidaa darteed, waa in aad fiiro gaar ah u marka aad gadaneyso impedance headphone a dooro model ugu habboon si looga hortago in ay xirtaan degdeg ah oo sii daraysa ee tayada shaqada.
