Sayansi ya chidziwitso cha mahedifoni

Malingana ndi mtundu wa dalaivala (transducer) ndi njira yovalachomverera m'makutus, mahedifoni amagawidwa makamaka:
Ma Headphone Amphamvu
Chomverera m'makutu chosunthandi mtundu wamba komanso wofala kwambiri wamakutu.Chigawo chake choyendetsa ndi choyankhulira chaching'ono chosuntha, ndipo diaphragm yolumikizidwa nayo imayendetsedwa ndi koyilo ya mawu mu mphamvu ya maginito yokhazikika kuti igwedezeke.Zomvera m'makutu zosuntha zimakhala zogwira mtima kwambiri, ndipo ambiri aiwo amatha kugwiritsidwa ntchito ngati madalaivala otulutsa pamutu pamawu, ndipo ndi odalirika komanso olimba.Nthawi zambiri, kukula kwa gawo la dalaivala kumapangitsa kuti foni yam'makutu ikhale yabwino.Pakadali pano, kuchuluka kwakukulu kwa ma driver amtundu wamakutu ogula ndi 70mm, omwe nthawi zambiri amakhala m'makutu.

Chitsulo cham'makutu chachitsulo chosuntha ndi foni yam'makutu yomwe imatumizidwa kumalo apakati a micro-diaphragm kupyolera mu ndodo yolumikizira yolondola, motero imatulutsa kugwedezeka ndi phokoso.Chitsulo chachitsulo chosuntha chimakhala ndi voliyumu yaying'ono kwambiri, ndipo kamangidwe kameneka kamachepetsa mphamvu ya khutu m'makutu ndipo ikhoza kuikidwa pamalo ozama mumtsinje wa khutu.
Zomverera za Iron
Zomvera m'makutu za ring-iron ndi zomvera m'makutuyokhala ndi phokoso loyendetsa-coil ndi kusuntha-chitsulo chosakanizidwa choyendetsa.Pali koyilo imodzi yosuntha + chitsulo chosuntha chimodzi, koyilo imodzi yosuntha + chitsulo chosuntha kawiri ndi zina.Ubwino wosuntha mayunitsi achitsulo ndi kutembenuka kwamagetsi kwamphamvu kwambiri komanso kugwedezeka kwamphamvu.Chifukwa chake, zomverera m'makutu zimakhala ndi chidwi chachikulu komanso kuchita bwino kwakanthawi kochepa, kotero kuti nyimbo zomveka komanso tsatanetsatane wanthawi yomweyo zomwe zimakhala zovuta kufotokozedwa ndi koyilo yoyambira yamphamvu zimawonetsedwa.
isomagnetic mahedifoni
Woyendetsa wa isomagneticm'makutuamafanana ndi olankhulira ochepetsetsa, ndipo phokoso la mawu lathyathyathya limayikidwa mu diaphragm yopyapyala, yofanana ndi mawonekedwe a bolodi losindikizidwa, lomwe lingapangitse kuti mphamvu yoyendetsa galimoto igawidwe mofanana.Maginito amakhazikika kumbali imodzi kapena zonse za diaphragm (mtundu wa push-pull), ndipo diaphragm imagwedezeka mu mphamvu ya maginito yomwe imapanga.Chidutswa cha m'makutu cha isomagnetic sichikhala chopepuka ngati cholumikizira cham'makutu cha electrostatic, koma chimakhala ndi malo ogwedezeka omwewo komanso mawu ofanana.Poyerekeza ndi zomvera m'makutu zamphamvu, mphamvu yake ndi yotsika ndipo sikophweka kuyendetsa.
makutu a electrostatic
Zomvera m'makutu za Electrostatic zili ndi ma diaphragm opepuka komanso opyapyala, opangidwa ndi magetsi okwera kwambiri a DC, ndipo mphamvu yamagetsi yofunikira polarization imasinthidwa kuchoka pakusintha kwapano, komanso imayendetsedwa ndi mabatire.The diaphragm imayimitsidwa m'munda wa electrostatic wopangidwa ndi mbale ziwiri zokhazikika zachitsulo (stators).Chomverera m'makutu cha electrostatic chiyenera kugwiritsa ntchito chokulitsa chapadera kuti chisinthire siginecha yomvera kukhala ma volt mazanamazana.Chomverera m'makutu ndi chachikulu, koma chimayankha ndipo chimatha kutulutsanso tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono kwambiri.
