Tus neeg hais lus yog ib qho ntawm cov khoom siv raw khoom ntawm cov khoom siv hluav taws xob acoustic. Cov khoom siv yooj yim rau kev tsim cov neeg hais lus tsis tshua muaj ntiaj teb NdFeB cov khoom siv hlau nplaum ruaj khov. Cov lus hais lus hlau nplaum feem ntau hu ua suab horn hlau nplaum.
Cov neeg hais lus ua haujlwm li cas?
Raws li tus quab, electromagnetic teb yog tau nyob rau hauv lub annular magnetic ceev ntawm qhov sib npaug Circuit Court, thiab lub suab coil txuas nrog tus hais lus cone yog muab tso rau hauv lub annular magnetic ceev. Cov khoom siv hlau nplaum ruaj khov yog nyob ib puag ncig los ntawm cov yoke hlau sab nraud, yog li txo qhov cuam tshuam ntawm sab nraud stray electromagnetic teb. Hloov chaw, nws tuaj yeem txo qhov loj ntawm cov nyhuv ntawm electromagnetic teb uas tsim los ntawm cov khoom siv hlau nplaum ruaj khov. Solenoid coils yog tsim thaum lub suab teb rau lub tshuab hluav taws xob hauv hluav taws xob tam sim no. Vim tias qhov kev hloov pauv ntawm tus nqi tam sim no, nws yuav coj ntau hom kev vibration frequencies, thiab tom qab ntawd thawb cov ntawv lub khob kom xa tawm ntau hom sijhawm thiab cov suab pom tseeb. Kev siv lub ntiaj teb tsis tshua muaj NdFeB hlau nplaum es tsis txhob siv cov ferrite cores los yog AlNiCo magnetic teb tsis tuaj yeem txhim kho qhov rhiab heev ntawm tus neeg hais lus, tab sis kuj txo qis tag nrho cov khoom siv sib nqus.
hlau nplaum nyob rau hauv hais lus
Ob hom khoom siv hlau nplaum ruaj khov uas feem ntau siv hauv cov neeg hais lus yog NdFeB hlau nplaum thiab ferrite cores. Tag nrho peb lub zog muaj zog, tab sis muaj lawv tus kheej qhov txawv txav.
Qhov zoo ntawm NdFeB yog cov nqi siab, kev ua haujlwm zoo ntawm lub cev, tab sis qhov tsis zoo tseem ceeb yog Curie kub, cov yam ntxwv kub tsis zoo, yooj yim delamination thiab corrosion.
Cov chaw tsim khoom ntawm lub xov tooj ntawm tes hauv qab lub mloog pob ntseg mloog yuav tsum kho nws cov muaj pes tsawg leeg thiab siv txoj kev kho saum npoo los txhim kho nws. Tsuas yog nyob rau hauv txoj kev no tuaj yeem tsim cov chaw tsim khoom nruab nrab thiab siab-tawm lub xov tooj ntawm tes earphone hais lus ua tau raws li cov kev xav tau ntawm kev siv tswv yim.
NdFeB belongs rau tiam thib peb ntawm lub ntiaj teb tsis tshua muaj hlau nplaum ruaj khov. Nws muaj cov yam ntxwv ntawm me me, lub teeb yuag thiab siab hlau nplaum. Nws yog ib qho chaw sib nqus nrog kev ua tau zoo-rau-tus nqi piv, thiab paub tias yog thawj qhov chaw sib nqus hauv kev lag luam magnetic teb.
Qhov kom zoo dua ntawm lub zog siab ceev ua rau NdFeB tsis tshua muaj lub ntiaj teb cov hlau nplaum uas siv dav hauv kev lag luam thiab kev siv tshuab automation.
Speaker Magnet (Lub suab hais lus Magnet)
Lub ferrite tub ntxhais yog hydroxide nrog cov khoom siv ferromagnetic.
Hais txog cov khoom siv hluav taws xob, qhov kev tiv thaiv ntawm ferrite cores yog ntau dua li cov ntaub ntawv hlau thiab aluminium alloy ruaj khov hlau nplaum cov ntaub ntawv, thiab nws kuj muaj cov khoom siv hluav taws xob siab.
Magnetically them mus tas li ferrites kuj tuaj yeem pom cov permeability ntawm cov zaus siab.
Yog li ntawd, cov hlau nplaum ferrite tau dhau los ua cov khoom siv hlau nplaum uas tsis yog xim hlau uas tau siv dav hauv kev ua haujlwm siab thiab tsis muaj zog tam sim no.
Ferrite hlau nplaum yog cov khoom siv hlau nplaum uas tsis yog xim hlau. Qhov no yog ib qho oxide sib xyaw nrog cov hlau nplaum ferric oxide thiab ib lossis ntau dua lwm cov hydroxides, uas feem ntau yog siv hauv cov neeg hais lus hauv txee thiab lwm yam twj paj nruag.
