Yenzelweni i-headphone amplifier

Njengoba igama liphakamisa, i-headphone amplifier iyithuluzi elizosetshenziselwa ukukhulisa isignali yomsindo lapho kuphuma khona, okungukuthi leyo esiyikhiphayo, isibonelo, ohlelweni lwe-hi-fi noma ucingo, bese siyifaka kuma-headphone ethu. . Vele, njengokujwayelekile, yonke idivaysi enokukhishwa kwe-headphone ine-amplifier eyakhelwe ngaphakathi, kepha kungenzeka ukuthi isiginali ibuthakathaka kakhulu ukuthi ingasanelisa ngokugcwele. Lokhu kuvame ukuba njalo ngabadlali abancane njengamakhompyutha aphathekayo, omakhalekhukhwini noma izidlali ze-mp3, lapho amandla esignali yokuphuma elinganiselwe. Ngokuxhuma i-amplifier enjalo, ama-headphone ethu azothola ingxenye eyengeziwe yamandla futhi azokwazi ukusebenzisa amandla aphelele ama-transducer awo.

Ungahlola kanjani ukuthi ama-headphone adinga i-amplifier

Ngeshwa, akuwona wonke ama-headphone azokwazi ukusebenzisa ngokugcwele i-amplifier eyengeziwe ngaphandle kokulahlekelwa ikhwalithi yomsindo. Ukuthi ama-headphone ethu angasebenzisa inani elingeziwe lamandla angahlolwa ngokuhlaziya imingcele evezwe ku-Ohms kanye nepharamitha ye-SPL. Isibonelo, uma ama-headphones ebonakala ngokuphikiswa okuphezulu okuvezwe ngama-ohms futhi ngesikhathi esifanayo aphansi i-SPL, khona-ke ama-headphone anjalo afaneleka kakhulu ukuthi isignali ikhuliswe ngenxa ye-amplifier eyengeziwe. Uma, ngakolunye uhlangothi, yomibili le mingcele isezingeni eliphansi, isignali kuyoba nzima ukuyikhulisa.

Izinhlobo zama-headphone amplifiers

Ama-headphone amplifiers angahlukaniswa ngenxa yokwakhiwa kwawo kanye nobuchwepheshe obusetshenziselwa lokhu. Okuthandwa kakhulu ama-transistor amplifiers, asekelwe kuma-transistors. I-amplifier enjalo iyathengeka futhi inikeza umsindo ongathathi hlangothi, wobuchwepheshe kakhulu, wekhwalithi enhle. Futhi singathenga i-amplifier esebenzisa ubuchwepheshe obachuma ngeminyaka yawo-60s. Ama-Tube amplifiers anabalandeli bazo kuze kube yilolu suku ngoba adala isimo esiyingqayizivele. Lobu buchwepheshe bubiza kakhulu ukukhiqiza, ngakho-ke izintengo zalezi zikhulisi zingabiza izikhathi eziningana kune-transistor. Futhi singathenga i-amplifier ehlanganisa ubuchwepheshe bamuva nobeminyaka edlule. Ama-amplifiers anjalo abizwa ngokuthi ama-hybrids futhi enzelwe abathandi bomculo abanolwazi abafuna umsindo oyingqayizivele wekhwalithi ephezulu. Esinye isigaba esingasetshenziswa ama-amplifiers amile nama-mobile amplifiers. Njengoba igama liphakamisa, eyokuqala isetshenziswa nabadlali abakhulu abanganyakazi, isb emakhaya eduze kwamasistimu e-hi-fi. Lezi zamuva zincane kakhulu futhi zivame ukusetshenziselwa ukukhulisa isignali kusuka kusidlali se-mp3 esiphathwayo noma umakhalekhukhwini. Lezi ezimile, ngaphandle kwamandla aphezulu, nazo zibonakala ngenani elikhulu lokufakwayo kwedijithali ne-analog. Amaselula, ngenxa yobuncane bawo, womabili anamandla amancane futhi anenombolo encane kakhulu yokufaka.

Isifinyezo

Sicela wazi ukuthi i-headphone amplifier iyisesekeli kuphela sesidlali sethu namahedfoni. Impela, lesi sisetshenziswa asikho isidingo sokulalela i-audiobook, kanti kubathandi bomculo bangempela abafuna ukusebenzisa ngokugcwele amandla ama-headphone abo, i-amplifier efanelekile ingacebisa kakhulu umuzwa wokulalela. Kufanele sikhumbule ukuthi kunenqwaba yalezi zinhlobo zama-amplifiers emakethe. Amamodeli akhethekile awafani kuphela ngokwamandla, kodwa futhi athuthuke kakhulu aneminye imisebenzi eyengeziwe. Ngakho-ke, ngaphambi kokuthenga, kufanelekile ukucabangela ukuthi yiziphi izici ze-amplifier esizikhathalela kakhulu. Ingabe kufanele kube amandla, uhlobo lokokufaka, noma mhlawumbe amanye amathuba agxile emsindweni? Isixazululo esihle kangaka ukuhlola ama-amplifiers ambalwa ahlukene kuma-headphones, esithenga kuwo idivayisi yethu.
