Izindaba - Ungakhetha Kanjani Imakrofoni Yedeskithophu

Ngokukhula okusheshayo kokuqoshwa kwevidiyo nokukopishwa, ukufundwa kwevidiyo ku-inthanethi, i-karaoke ebukhoma, njll. eminyakeni yamuva nje, isidingo semishini yehadiwe sesiphinde saba intokozo yabakhiqizi abaningi bemakrofoni.

Abangani abaningi basibuze ukuthi singakhetha kanjani ukuqopha imibhobho yedeskithophu .Njengomkhiqizi wemakrofoni ohamba phambili kulo mkhakha, singathanda ukunikeza izeluleko mayelana nalesi sici.

Amamakrofoni edeskithophu ngokuyinhloko anezindawo ezimbili zokusebenzelana: I-XLR ne-USB.Namuhla, sethula kakhulu imibhobho ye-USB yedeskithophu.

Ngakho-ke, yimuphi umehluko phakathi kwamakrofoni we-XLR nemakrofoni ye-USB?
Amamakrofoni e-USB ngokuvamile asetshenziswa ekubhalweni ngekhompyutha, ukuqoshwa kwezwi komdlalo, ukufunda kwekilasi ku-inthanethi, i-karaoke ebukhoma nezinye izimo.Ukusebenza kulula futhi kulula, ipulaki nokudlala, futhi ifanele abaqalayo.

Imakrofoni ye-XLR ivamise ukusetshenziswa ekudwebeni okuphrofeshinali nokuqoshwa kwe-karaoke eku-inthanethi.Umsebenzi wokuxhuma uyinkimbinkimbi futhi udinga isisekelo esithile somsindo nokujwayelana nesofthiwe yokurekhoda echwepheshile.Lolu hlobo lwemakrofoni lunezidingo eziphakeme zemvelo yomsindo wokurekhoda futhi ifanele izindawo ezikude.

Lapho uthenga imakrofoni ye-USB yedeskithophu, udinga ukuqonda ngokucacile imingcele nezici zombhobho ngamunye.

Ngokuvamile, amapharamitha angumongo wamakrofoni we-USB ancike kakhulu kulezi zinkomba ezilandelayo:

Ukuzwela

Ukuzwela kusho ikhono lombhobho lokuguqula ingcindezi yomsindo ibe ileveli.Ngokuvamile, ukuphakama kokuzwela kombhobho, amandla okukhipha izinga aqina.Imakrofoni ezwela kakhulu ilusizo kakhulu ekubambeni imisindo emincane.

Isampula isilinganiso/bit rate

Ngokuvamile, ukuphakama kwezinga lokusampula kanye nezinga lebhithi lombhobho we-USB, kucace kakhudlwana ikhwalithi yomsindo orekhodiwe kanye nokwethembeka kwezwi.
Njengamanje, izinga lamasampula ochungechunge angama-22 liye laqedwa kancane kancane yimboni yokuqopha yochwepheshe.Kulezi zinsuku, izitudiyo zokurekhoda zedijithali zibeka kuqala ukusetshenziswa kwezicaciso zomsindo we-HD, okungukuthi, 24bit/48KHz, 24bit/96KHz, kanye no-24bit/192KHz.

Ijika lokuphendula imvamisa

Ngokombono, ekamelweni elichwepheshile le-acoustic elingazwakali, ububanzi bomkhawulo wefrikhwensi engezwa indlebe yomuntu buphakathi kuka-20Hz no-20KHz, abakhiqizi abaningi bemibhobho bamaka i-fr.ijika lempendulo elilinganayo ngaphakathi kwalobu bubanzi.

Isilinganiso somsindo wesignali

Isilinganiso sesignali-kuya-kumsindo sisho isilinganiso samandla esignali yokuphumayo yemakrofoni kumandla omsindo, ngokuvamile avezwa ngama-decibel (dB).

Ngokuvamile, ukuphakama kwesilinganiso se-signal-to-noise yemakrofoni, iphansi lomsindo lincane kanye nemfuhlumfuhlu exutshwe kusignali yezwi lomuntu, kanye nekhwalithi yomsindo wokudlala icace kakhudlwana.Uma isilinganiso sesignali-kumsindo siphansi kakhulu, sizobangela ukuphazamiseka okukhulu kwaphansi komsindo lapho isignali yemakrofoni ifakwa, futhi lonke uhla lomsindo luzozwakala lunodaka futhi lungacacile.

Ukusebenza kwepharamitha yesiginali-kuya-kumsindo wemibhobho ye-USB ngokuvamile kucishe kube ngu-60-70dB.Isilinganiso se-signal-to-noise sochungechunge oluthile lwamamakrofoni e-USB aphakathi nendawo ukuya phezulu anokulungiselelwa kokusebenza okuhle angafinyelela ngaphezu kuka-80dB.

Izinga eliphezulu lokucindezela komsindo

Izinga lokucindezela komsindo libhekisela kumthamo omkhulu wengcindezi yomsindo wesimo esingaguquki umbhobho ongamelana nayo.Ukucindezela komsindo kuvame ukusetshenziswa njengenani elibonakalayo ukuchaza usayizi wamagagasi omsindo, ne-SPL njengeyunithi.

Ukubekezelela ingcindezi yomsindo wombhobho kuyisici esibalulekile okufanele sicatshangelwe lapho uqopha.Ngoba ukucindezela komsindo ngokungenakugwenywa kuhambisana nokuhlanekezela okuphelele kwe-harmonic (THD).Ngokuvamile, ukugcwala komfutho womsindo wombhobho kungabangela kalula ukuhlanekezela komsindo, futhi lapho izinga lokucindezela komsindo likhulu, kuyancipha ukuhlanekezela kwezwi.

Njengomkhiqizi wombhobho ohamba phambili wobuchwepheshe obuphezulu, sobabili singahlinzeka nge-ODM ne-OEM ngemikhiqizo eminingi.Ngezansi i-U yethu edayisa kakhuluImakrofoni yedeskithophu ye-SB.
