Koj puas tuaj yeem xav txog lub xov tooj tsis muaj tus hais lus hauv lossis lub suab paj nruag tsis muaj cov hais lus loj? Tsis yog, koj tsis tuaj yeem vim nws yuav tsis muaj txiaj ntsig los yuav lub xov tooj uas tsis tsim suab lossis mus rau kev hais kwv txhiaj uas tus neeg ua yeeb yam tsuas yog hu nkauj rau thawj kab. Cov neeg hais lus tseem ceeb rau cov khoom siv hluav taws xob thiab cov khoom siv digital raws li cov khoom siv no yog rau peb lub neej txhua hnub. Thiab, koj puas paub dab tsi nyob hauv plawv ntawm koj lub smartphone tus hais lus? Ib tug minuscule hlau nplaum. Yog tsis muaj cov hlau nplaum nyob hauv nruab nrab ntawm nws, tus neeg hais lus yuav tsis tuaj yeem hloov cov teeb liab hluav taws xob rau hauv cov khoom siv hluav taws xob xws li suab.
Daim ntawv qhia ceev ntawm keeb kwm ntawm cov neeg hais lus; Johann Philip Reis tau tsim thawj lub suab xa tawm hauv xyoo 1861 siv lub kauj thiab lub diaphragm uas tuaj yeem hloov suab nthwv dej rau hauv cov teeb liab hluav taws xob. Tom qab xyoo 1876, siv cov hlau nplaum sib nqus kom xa suab, Alexander Graham Bell tau tsim thawj lub xov tooj uas siv tau. Nyob rau hauv lub xyoo pua 20th, cov hlau nplaum tas mus li hloov cov hlau nplaum hloov pauv qhov ua tau zoo thiab kev cog lus ntawm cov neeg hais lus. Hauv xyoo 1980, Neodymium (NdFeB) tau coj lub ntiaj teb ntawm cov neeg hais lus los ntawm cua daj cua dub nrog nws qhov sib txawv tsis sib xws ntawm lub zog thiab kev cog lus.
Fast-forward mus rau 2024, thiab peb tau los ntev los ntawm coils thiab diaphragms. Feem ntau ntawm cov suab uas koj hnov txhua txhua hnub yog los ntawm cov neeg hais lus, tab sis koj puas tau nres thiab xav paub seb cov hlau nplaum tseem ceeb npaum li cas rau cov neeg hais lus? Zoo, cia peb nrhiav.
Magnet yog dab tsi?
Cias muab, ib tug hlau nplaum yog ib yam khoom uas generates ib tug invisible teb piv txwv li, ib tug magnetic teb. Cov hlau nplaum yog lub zog muaj zog uas tuaj yeem nyiam lwm cov ntaub ntawv xws li hlau lossis cobalt los yog tshem tawm lawv. Raws li lawv lub peev xwm los tsim cov hlau nplaum, ntawm no yog ob pawg tseem ceeb ntawm cov hlau nplaum.
Cov hlau nplaum ruaj khov - cov hlau nplaum ruaj khov yog cov hlau nplaum uas muaj cov hlau nplaum ruaj khov. Nws tsis tas yuav muaj lwm lub zog los tsim ib qho chaw sib nqus tas li. Piv txwv ntawm cov hlau nplaum tas mus li muaj xws li Neodymium, hlau oxide, thiab barium ferrite.
Cov hlau nplaum ib ntus - cov hlau nplaum ib ntus yog cov hlau nplaum uas tuaj yeem tsim cov hlau nplaum ib ntus tsuas yog thaum lawv nyob hauv lwm qhov chaw sib nqus. Yog li, lawv xav tau ib qho chaw sib nqus txawv teb chaws los qhia cov khoom sib nqus.
Ib qho chaw ruaj khov, tas li, thiab muaj zog sib nqus yog qhov tseem ceeb rau kev ua haujlwm ntawm tus hais lus. Qhov no yog vim li cas cov hlau nplaum ruaj khov yog qhov tseem ceeb tshaj plaws rau cov neeg hais lus.
Science of Suab
Lwm qhov uas koj yuav tsum nkag siab kom nkag siab txog kev ua haujlwm ntawm tus hais lus zoo dua yog Suab. Nws yog ib daim ntawv ntawm lub zog uas yog tsim los ntawm kev co ntawm hais nyob rau hauv ib tug nruab nrab xws li huab cua los yog dej.
Ib qho khoom vibrating tsim cov nthwv dej siab uas dhau los ntawm qhov nruab nrab thiab ua rau lub suab tsis muaj zog. Lub suab nthwv dej tom qab ncav peb pob ntseg ua rau peb lub pob ntseg vibrate uas peb lub hlwb txhais tau tias yog lub suab ua rau peb mloog nkauj lossis lwm tus neeg lub suab.
Ua raws li cov xwm txheej ntuj no, cov neeg hais lus hloov cov teeb liab hluav taws xob tuaj rau hauv lub zog siv hluav taws xob tsim lub suab nthwv dej. Cov hlau nplaum ua lub luag haujlwm loj hauv kev txav ntawm lub diaphragm hauv tus hais lus thiab cov suab nrov nrov. Lub diaphragm tsim suab nthwv dej thaum nws vibrates.
Cov neeg hais lus ua haujlwm li cas?
Lub suab coil, cov hlau nplaum ruaj khov, thiab lub diaphragm yog peb lub ntsiab lus tseem ceeb hauv tus neeg hais lus uas ua lub luag haujlwm tseem ceeb hauv kev tsim suab. Nov yog li cas cov neeg hais lus ua haujlwm siv cov khoom no.
Lub suab coil-tus neeg hais lus lub lag luam pib nrog qhov induction ntawm hluav taws xob tam sim no los ntawm lub suab coil uas yog lub kauj hlau. Nyob rau hauv teb rau cov hluav taws xob tam sim no ntws los ntawm nws, lub suab coil pib tsim ib tug magnetic teb. Lub suab coil txoj hauj lwm nyob rau hauv tus neeg hais lus kuj tseem ceeb heev rau cov suab nrov nrov. Nws yog muab tso rau hauv ib tug ruaj khov hlau nplaum magnetic teb thiab kev sib cuam tshuam ntawm ob variating magnetic teb yuav siv sij hawm cov txheej txheem ntawm suab ntau lawm.
Cov hlau nplaum ruaj khovRaws li peb twb paub lawm, ib qho chaw sib nqus tsis tu ncua yog ib yam ntxwv ntawm cov hlau nplaum ruaj khov. Ib qho hlau nplaum ruaj khov raug xaiv raws li lub zog ntawm nws qhov chaw sib nqus uas tseem yog qhov tseem ceeb rau tus neeg hais lus txoj haujlwm. Thaum cov hlau nplaum tsim los ntawm cov hlau nplaum ruaj khov thiab lub suab coil coincide, lawv ua rau lub suab coil txav nrawm uas ua rau lub zog ntawm lub diaphragm.
Diaphragm-lub diaphragm yog txuas ncaj qha mus rau lub suab coil thiab raws li lub suab coil txav mus rau hauv cov lus teb rau kev sib cuam tshuam ntawm ob lub magnetic teb, lub diaphragm uas yog ib tug nyias thiab saj zawg zog daim nyias nyias kuj txav mus los. Qhov kev txav ntawm lub diaphragm no pib ib qho dej ntws ntawm cov huab cua tsim suab nthwv dej.
Thiab qhov ntawd yog li cas tus neeg hais lus tsim suab hauv kev teb rau lub teeb liab hluav taws xob. Ib zaug ntxiv, txoj haujlwm ntawm lub suab coil thiab lub zog ntawm cov hlau nplaum ruaj khov ntawm cov hlau nplaum sib nqus yog qhov tseem ceeb rau kev tsim cov suab tsis zoo uas tsom iav cov teeb liab hluav taws xob muab rau tus neeg hais lus hauv thawj kauj ruam. Ib tus neeg hais lus nrog cov qauv tsim tau zoo thiab cov khoom siv zoo tshaj plaws tuaj yeem hloov hluav taws xob tau yooj yim rau hauv lub zog suab nrog kev cuam tshuam tsawg.
Vim li cas Magnets tseem ceeb hauv cov neeg hais lus?
Nov yog cov laj thawj vim li cas hlau nplaum tseem ceeb hauv cov neeg hais lus, qee qhov koj twb paub los ntawm cov ntsiab lus dhau los.
Tsim ib tug magnetic teb
