Kuyini impedance ka-headphones

Ama-headphone impedance - lena ukumelana yabo emnyango. Ixhomeke ke, izici eziningi lobuchwepheshe nokusebenza kuzo.

Uma impedance eliphansi headphones (25 ohms noma ngaphansi), zidinga amandla kancane ukunikeza umsindo eliphezulu. Lezi amaspikha kahle zokuhamba ukusetshenziswa namadivayisi ezifana umculo abadlali, omakhalekhukhwini kanye namanye amadivayisi ephathekayo.

Futhi uma headphones impedance 25 ohms ngaphezulu, zidinga amandla nangokwengeziwe okusezingeni eliphezulu okukhipha ezingeni. Lokhu Ukumelana uwuvikela umonakalo kungenzeka kubangelwa overloads. Lezi-headphone ingasetshenziswa ebanzi ezahlukene audiotehnicheskih amadivaysi. Ngokwesibonelo, lezi zibandakanya esetshenziswa dj-yokubeka uphawu imodeli, ukumelana okuzisholo okuyinto mayelana 25-70 ohms.

Uma impedance embobeni uphansi, ziba usengozini yokuthola umonakalo uma usebenzisa yokukhulisa umsindo ephezulu amandla. Uma, ukwenza isibonelo, ukuxhuma-headphone nge impedance ongaphakeme ngokumiswa dj-ni futhi uzosebenzisa yona umthamo wayo ngokugcwele, kufanele nabo, cishe qhumisa.

Ngakho, liyini impedance elikhulu? Ama-headphone usetshenziselwe proslushavaniya umdlali audio noma laptop ephathekayo, kufanele kuhle abe ukumelana mayelana 16-20 ohms lobukhali okungenani 100 dB / MW. Uma idivayisi yakho kuyahlangabezana nezindinganiso European yevolumu esiphezulu, kungcono ukuba ukhethe ama-headphone nge impedance 16 ohms, kwazise lezi amadivaysi amandla esiphezulu namanje esingaphansi kwabanye.

Ngokuvamile, kutuswa okuzisholo impedance -headphone kuboniswe embhalweni idivayisi.

Kubalulekile ukuba acabangele impedance ka-headphones, njengoba wonke amamodeli kufanele sisebenze amanani angalingani amandla kagesi kanye ukumelana. imodeli ngamunye embobeni ibalwa ngokuqondile futhi ulinganiswe ukuhlangabezana ethize umthwalo ivolumu. Lokhu kuqinisekisa hhayi kuphela ukuphepha ukusetshenziswa kobuchwepheshe, kodwa futhi bandisa yempilo yayo.

Ngaphambili, eminyakeni 60-80, ngokuvamile zisebenzisa okusezingeni eliphezulu impedance-headphone, kusukela kudivayisi amandla okukhipha sikhathi laliphezulu kakhulu. Uma usuqalile resistors esetshenziswa, wehlise voltage okukhiphayo. Ngo-1996, it ubeke indinganiso ku impedance embobeni - 120 Ohm. Lokhu sekube nomthelela obalulekile zokukhiqiza ukuthuthukiswa onobuhle impedance okusezingeni eliphezulu, kodwa ngesikhathi esifanayo ingathiyeki ukuqhubeka kwezinye iziqondiso. Ngo-2009, yokuthengisa omkhulu we-iPod, okuholela imishini nge ukumelana ongaphakeme iye yatha- okusezingeni eliphezulu. Ngakho-ke, ukuthuthukiswa-headphone nge impedance ephansi, wathola umfutho omusha.

Ngakho, impedance we - omunye, uma hhayi kakhulu, kodwa namanje izici ebalulekile headphones. We khetha imodeli yakho kumele athobele imishini elalelwayo, oyisebenzisayo, i-esiphezulu izinga umsindo futhi ukuqinisekisa operation esitebeleni evamile. Ngakho-ke, kufanele sinake lapho ukuthenga impedance embobeni bese ukhetha imodeli elifanele kakhulu ukuvimbela ukuguga okusheshayo futhi Ukuwohloka izinga lomsebenzi.
