Indlela yokukhetha iifowuni?

Umculo uyonwabile umphefumlo. Abambalwa bethu bathanda ukuphulaphula umculo kunye neengoma ekhaya, kwizithuthi zikawonkewonke okanye nakumsebenzi. Futhi bengathandi ukuphazamisa abanye, abaninzi banqwenela ukusebenzisa i-headphones. Kodwa ukwenza umculo ube mnandi, ngenxa yomsindo ogqithiseleyo okanye umgangatho omhle we-acoustics indlebe yakho ayihluphekanga, sincoma ukuthenga izixhobo eziphezulu. Ewe, ukuba ingxaki yokukhetha i-headset kunzima kuwe, inqaku lethu lincedo.

Iintlobo kunye neentlobo ze-headphones

Ngaphambi kokuba ushiye indlu ukuze uthenge i-headphone, qalisa ukugqiba ngeenjongo zokuzifunayo. Iimarike zanamhlanje zinika iintlobo ezininzi zefowuni:

1. Ngokusekwe kwindlela yokuyila, i-headphone i-plug-in kunye ne-overhead. Kucacile ukuba iimveliso ezifakwe ezindlebeni azikwazi ukuqinisekisa isandi esihle, kodwa zilungele ukusebenzisa kwisitrato okanye kwisithuthi. Ukuphulaphula umculo kumakhaya, kungcono ukuthenga ii-invoyisi. Kwakhona kufuneka benze ukhetho lwee-headphones.
2. I-headphone ikwahlula ngokohlobo lwesinamathiselo. I-arc yokwakheka kwe-arc ifaka intloko kwaye idibanisa izitya zombini. Ngamanye amaxesha kwi-headphone i-arch iqhubela phantsi kwinxalenye ye-occipital. Kweminye imodeli, iikomityi ziqhotyoshelweyo zisebenzisa iiklipthi okanye ii-oval hooks to theric.
3. Ngokuxhomekeke kwi-design acoustic, kukho ii-headphones ezivaliweyo, ezivaliweyo kunye nezivulekile. Uhlobo oluvaliweyo aluvumeli izandi zangaphandle, ngaloo ndlela zinika ingxolo ephakamileyo. Gcina nje ukhumbule ukuba badala uxinzelelo olunzulu entlebeni. Ukucinga malunga nendlela yokukhetha i-headphones kwikhomputha apho usebenza khona kwiofisi enomsindo, ukhethe izinto ezizodwa ezivaliweyo: kunye nezandi zasemzini zixakile kwaye izindlebe azihlupheki. Vula i-headphones, nangona kunjalo, kwaye makhuphe ngaphandle kwengxolo, kodwa isandi sisemvelo.
4. Xa ukhetha indlela yokukhetha i-headphone efanelekileyo, qwalasela indlela yokudluliselwa kwesandi. Iifowuni zefowuni zixhomekeke kumthombo wecingo elivakalayo. Ngendlela engena-wire, i-headphones zixhunyiwe kwisixhobo ngesinye ishaneli, kodwa ngaphandle kokusetyenziswa kwentambo. Nangona kunjalo, xa ukhetha ii-headphone ezingenaselula, khumbula ukuba umgangatho ozwakalayo wehla.

Ezinye iifowuni iinkcukacha

Ukongezelela kwiintlobo ezahlukeneyo kunye neentlobo, iintloko zee-headphones zinamaparitha ahlukeneyo. Umzekelo, umgangatho wezwi uqikelele uhla lwamanqanaba, oluphakathi kwe-20 ukuya kwi-20,000 i-Hz. Umthamo we-headphone umsindo uchatshazelwa uvelwano lwabo, olulinganiswa kwi-decibels. Iimodeli ezithengileyo ezithengileyo kunye novelwano olungekho ngaphantsi kwe-100 dB, ngaphandle koko umculo awunakuvakala, ngokukodwa kwimeko enomsindo. Xa ukhetha i-headphones, ukuxhatshazwa kwakhona kuyaqwalaselwa, eyahluka kwi-16 ukuya kuma-600 ohms. Kubadlali abaqhelekileyo, iikhomputha zithatha iimveliso kunye nomqondiso we-23 ukuya ku-300 ohms. Ukusebenza kwi-studio ngokuqhelekileyo kufumana imodeli enoxinzelelo. Ngokuphathelele ukuphazamiseka kwe-harmonic, le pharamitha inquma ukuchaneka kokusasazwa kwesaziso somsindo. Ngokuqhelekileyo lo mfanekiso ungaphantsi kwe-1%.

Ngamanye amaxesha i-amplifier ephathekayo isetyenziselwa ukukhulisa isandi sekhonofoni kwaye idlulisele umqondiso kwipropati ngaphandle kokuphazamiseka, elula ukuyenza loo misebenzi. Kule meko, ukhetho lwe-headphone amplifier lusekelwe kwiimpawu zeso sixhobo. Umzekelo, iimodeli zeplagi-in, ama-amplifiers ane-output output ye-0.5-2 V akhethiweyo, kuba izixhobo ezine-voltage ezivela ku-1 ukuya ku-5V zifanelekile kwizinto ezingaphezulu. Ukongeza, ukwenzela ukuba i-headphones izandile ngaphandle kokuphazamiseka, kubalulekile ukukhetha ukwandisa ukulinganiselwa okufanayo. Oku kuthetha ukuba i-impedance ephezulu ye-amplifier akufanele iphakame ngaphezu kweefowuni.

Ixesha lokubanda lijikeleze ekhoneni, ngoko kufuneka uqaphele ukuba izixhobo zakho "azifaki". Funda kabanzi malunga neentloko ezifudumeleyo .
