Indlela yokukhetha i-headphone?

Umculo umnandi ngomphefumulo. Abambalwa bethu bathanda ukulalela umculo nezingoma ekhaya, ezokuthutha zomphakathi noma ngisho nasemsebenzini. Futhi engafuni ukuphazamisa abanye, abaningi bakhetha ukusebenzisa i-headphones. Kodwa ukwenza umculo ujabule, ngenxa yomsindo owedlulele noma izinga elibi le-acoustics indlebe yakho ayihlupheki, sincoma ukuthenga imishini ephezulu. Yebo, uma inkinga yokukhetha i-headset inzima kuwe, isihloko sethu siwusizo.

Izinhlobo nezinhlobo ze-headphones

Ngaphambi kokuba ushiye indlu ukuthenga i-headphone, qala uthathe ukuthi yini oyidingayo. Imakethe yanamuhla inikeza izinhlobo eziningana zale divayisi:

1. Ngokusekelwe ekuklanyeni, i-headphone i-plug-in futhi ngaphezulu. Kusobala ukuthi imikhiqizo efakwe ezindlebeni ayikwazi ukuqinisekisa isihlabelelo esihle kakhulu, kodwa kulula ukuyisebenzisa emgwaqweni noma ekuthuthweni. Ukuze ulalele umculo ekhaya, kungcono ukuthenga ama-invoyisi. Kufanele futhi bakhethe ukukhetha ama-headphones.
2. Ama-headphone ahlukaniswe ngokusho kohlobo lokunamathiselwe. I-arc yokugcizelela yendabuko igoba ikhanda bese ixhuma zombili izitsha zomculo komunye nomunye. Ngezinye izikhathi ku-headphones umcibisholo ugijima ngaphansi kwengxenye ye-occipital. Kwamanye amamodeli, izinkomishi zihlanganiswa besebenzisa iziqeshana noma izingwegwe ezivundlile.
3. Kuye ngomklamo we-acoustic, kunezinhloko ze-headphones ezivaliwe, ezivaliwe nezivulekile. Uhlobo oluvaliwe aluvumeli imisindo yangaphandle, ngaleyo ndlela lunikeze umsindo omuhle kakhulu wokuhlukaniswa. Vele uhlale ukhumbule ukuthi benza ukucindezeleka okuqinile endlebeni. Uma ucabanga ukuthi ungakhetha kanjani i-headphone yekhompyutha lapho usebenza khona ehhovisi elimnandi, yenza okuthandwayo kumamodeli angavaliwe: nezindlebe zangaphandle zifakiwe futhi izindlebe azihlupheki. Vula i-headphones, noma kunjalo, uvumele umsindo ongaphandle, kodwa umsindo unemvelo.
4. Uma unquma indlela yokukhetha i-headphone efanele, cabangela indlela yokudlulisa umsindo. Ama-headphone aphikisiwe axhuma emthonjeni wocingo lomsindo. Ngendlela engenantambo, i-headphones ixhunywe kudivayisi ngenye isiteshi, kodwa ngaphandle kokusebenzisa ucingo. Nokho, uma ukhetha imisindo engenazintambo, khumbula ukuthi izinga elizwakalayo liyancipha.

Ezinye izimpawu zekhanda

Ngaphezu kwezinhlobo ezahlukene nezinhlobo, i-headphones inemingcele ehlukile. Isibonelo, ikhwalithi yomsindo inquma ibanga lemvamisa, eliphakathi kuka-20 kuya ku-20,000 Hz. Umthamo we-headphones umsindo uphazamiseka ukuzwela kwawo, okulinganiselwe kuma-decibel. Amamodeli wokuthenga aphelele ngokuzwela okungaphansi kuka-100 dB, kungenjalo umculo ngeke uzwakale kalula, ikakhulukazi endaweni enomsindo. Uma ukhetha ama-headphone, ukumelana nakho kuyabhekwa, okuyinto ehluka kusuka kuma-16 kuya ku-600 ohms. Abadlali abavamile, amakhompiyutha athatha imikhiqizo ene-23 kuya ku-300 ohms. Ukuze usebenze kule studio ngokuvamile uthole amamodeli anamazinga amakhulu. Ngokuqondene nokuphazamiseka kwe-harmonic, le parameter inquma ukunemba kokudluliswa kwesignali yomsindo wokufaka. Ngokuvamile lesi sibalo singaphansi kwe-1%.

Ngezinye izikhathi i-amplifier ephathekayo isetshenziselwa ukukhulisa umsindo wekhanda lomakhalekhukhwini futhi udlulisele isignali emkhatsini wokukhipha ngaphandle kokuphazamiseka, okubhekana kalula nemisebenzi enjalo. Kulokhu, ukukhethwa kwekhanda lokukhulisa i-headphone kuncike kwizici zedivayisi uqobo. Isibonelo, amamodeli we-plug-in, ama-amplifiers ane-voltage okukhipha ye-0.5-2 V akhethiwe, ngoba amadivaysi ane-voltage esuka ku-1 kuya ku-5 V afaneleka kakhulu. Ngaphezu kwalokho, ukuze i-headphones izwakala ngaphandle kokuphazamiseka, kubalulekile ukukhetha ukukhulisa ngokulinganiselwa okufanayo. Lokhu kusho ukuthi impedance enkulu ye-amplifier akumele ibe ngaphezulu kune-headphones.

Inkathi yokubandayo iseduze kwekhoneni, ngakho-ke udinga ukunakekelwa ukuthi imishini yakho "ayifaki". Funda kabanzi mayelana nama- headphone afudumele .
