Headphone paub science

Raws li hom tsav tsheb (transducer) thiab txoj kev hnavlub mloog pob ntsegs, headphones feem ntau muab faib ua:
Dynamic Headphones
Moving coil earphoneyog hom pob ntseg nrov tshaj plaws thiab feem ntau.Nws lub tsev tsav tsheb yog lub me me txav coil hais lus, thiab lub diaphragm txuas nrog nws yog tsav los ntawm lub suab coil nyob rau hauv qhov chaw sib nqus mus tas li kom vibrate.Moving-coil earphones muaj txiaj ntsig zoo dua, thiab feem ntau ntawm lawv tuaj yeem siv los ua lub mloog pob ntseg tso zis tsav tsheb rau lub suab, thiab txhim khu kev qha thiab ruaj khov.Feem ntau hais lus, qhov loj ntawm txoj kab uas hla ntawm lub tsev tsav tsheb, qhov kev ua tau zoo ntawm lub pob ntseg zoo dua.Tam sim no, lub siab tshaj plaws txoj kab uas hla ntawm tus tsav tsheb nyob rau hauv cov neeg siv khoom earphones yog 70 hli, uas yog feem ntau flagship earphones.
Tsiv Hlau Headphones
Lub pob ntseg txav hlau yog lub pob ntseg uas tau xa mus rau qhov chaw nruab nrab ntawm micro-diaphragm los ntawm cov pas nrig sib txuas, yog li tsim kev vibration thiab suab.Lub pob ntseg txav ntawm lub pob ntseg muaj qhov ntim me me, thiab cov qauv no ua tau zoo txo ​​qhov ntim ntawm lub pob ntseg hauv pob ntseg thiab tuaj yeem muab tso rau hauv qhov tob tob hauv pob ntseg.
Nplhaib Hlau Headphones
Lub nplhaib-hlau earphones yog lub pob ntsegnrog txav-coil thiab txav-hlau hybrid tsav suab.Muaj ib qho txav coil + ib qho txav hlau, ib qho txav coil + ob chav txav hlau thiab lwm yam qauv.Qhov zoo ntawm kev txav cov hlau yog siab electro-acoustic conversion efficiency thiab sib zog vibration lub cev.Yog li ntawd, lub mloog pob ntseg muaj qhov rhiab heev thiab kev ua haujlwm zoo, yog li cov suab paj nruag muaj zog thiab cov ntsiab lus tam sim uas nyuaj rau kev nthuav tawm los ntawm cov thawj dynamic coil yog qhov tseem ceeb.
isomagnetic headphones
Tus tsav tsheb ntawm isomagneticpob ntsegzoo ib yam li tus neeg hais lus txo qis, thiab lub suab tiaj tus coil yog embedded nyob rau hauv ib tug nyias diaphragm, zoo ib yam li cov qauv ntawm ib tug luam Circuit Court board, uas yuav ua tau kom lub zog tsav tsheb sib npaug zos.Cov hlau nplaum yog tsom rau ntawm ib lossis ob sab ntawm lub diaphragm (push-rub type), thiab cov diaphragm vibrates hauv cov hlau nplaum uas nws tsim.Lub diaphragm ntawm lub pob ntseg isomagnetic tsis yog lub teeb raws li lub diaphragm ntawm lub pob ntseg electrostatic, tab sis nws muaj tib qhov chaw vibration loj thiab cov suab zoo sib xws.Piv nrog rau lub mloog pob ntseg dynamic, qhov ua tau zoo yog qis dua thiab nws tsis yooj yim rau kev tsav tsheb.
electrostatic earphones
Electrostatic earphones muaj lub teeb thiab nyias diaphragms, polarized los ntawm lub siab DC voltage, thiab lub zog hluav taws xob xav tau rau polarization yog hloov dua siab tshiab los ntawm alternating tam sim no, thiab lawv kuj yog powered los ntawm roj teeb.Lub diaphragm raug tshem tawm hauv qhov chaw electrostatic tsim los ntawm ob daim hlau ruaj khov (stators).Lub mloog pob ntseg electrostatic yuav tsum tau siv lub tshuab hluav taws xob tshwj xeeb los hloov lub suab teeb liab mus rau lub teeb liab hluav taws xob ntau pua volts.Lub mloog pob ntseg yog qhov loj, tab sis nws teb tau thiab muaj peev xwm rov tsim dua txhua yam ntawm cov ntsiab lus me me uas tsis tshua muaj kev cuam tshuam.
