Lub hauv paus ntsiab lus ntawm lub suab nrov
Electrodynamic loudspeaker tseem hu ua txav coil loudspeaker.Nws yog ib qho hluav taws xob transducer nrog hluav taws xob txoj cai.Nws yog lub suab nrov tshaj plaws tam sim no, rau peb lub ntsiab lus:
1. Cov qauv hluav taws xob nrov nrov yog qhov yooj yim, tsim tau yooj yim, thiab nws tus kheej tsis' tsis xav tau qhov chaw loj, ua rau tus nqi pheej yig, tuaj yeem siv dav.
2. Lub suab nrov no tuaj yeem ua tau zoo heev, thiab tuaj yeem tau txais cov lus teb tsis sib xws hauv nruab nrab zaus band.
3. Lub suab nrov zoo li no hauv kev txhim kho txuas ntxiv, ntau xyoo dhau los ntawm keeb kwm ntawm kev txhim kho lub suab nrov nrov, yog keeb kwm ntawm kev txhim kho txuas ntxiv ntawm cov suab nrov tsim, thev naus laus zis, cov ntaub ntawv, tab sis kuj yog keeb kwm ntawm kev ua tau zoo nce qib nrog The Times.
Tus qauv ntawm lub khob hais lus tuaj yeem muab faib ua peb ntu:
1. Vibration system muaj xws li diaphragm, lub suab coil, centering phaj, plua plav npog, thiab lwm yam
2. Sib nqus Circuit Court system muaj xws li sib nqus sab sauv phaj, sib nqus kem, sib nqus phaj qis, hlau nplaum, thiab lwm yam
3. Lub koom haum pab cuam suav nrog cov phiab thav duab, qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.
Raws li Faraday' txoj cai lij choj, thaum tus neeg nqa khoom nqa tam sim no dhau los ntawm qhov chaw sib nqus, nws yuav tau txais lub zog hluav taws xob, uas nws cov kev taw qhia ua raws li Flemings txoj cai sab laug. Lub zog yog perpendicular mus rau cov kev taw qhia ntawm lub tam sim no thiab magnetic teb, thiab lub zog yog proportional rau lub tam sim no, hlau ntev thiab sib nqus flux ceev.Thaum lub suab coil inputs alternating suab tam sim no, lub suab coil yog raug rau ib tug alternating tsav tsheb quab yuam. tsim alternating tsab ntawv tsa suab, uas tsav cov ntawv phwj rau vibrate thiab pheej thawb huab cua mus rau suab.
