Lub tshuab hluav taws xob yog lub tshuab hluav taws xob tshwj xeeb tsim los hloov lub teeb liab me me uas los ntawm qhov chaw mus rau lub teeb liab muaj zog dua. Tom qab tag nrho, txhawm rau tswj cov khoom siv hluav taws xob-acoustic transducer, piv txwv li, lub mloog pob ntseg lossis lub suab nrov, koj xav tau lub teeb liab muaj zog yam tsis muaj kev cuam tshuam, thiab lub hauv paus feem ntau tsis tuaj yeem muab lub teeb liab xav tau lossis cuam tshuam nrog kev cuam tshuam tsis zoo.
Lub tshuab hluav taws xob tuaj yeem yog ib qho khoom siv ywj pheej nrog nws tus kheej lub vaj huam sib luag thiab kev tswj hwm, lossis nws tuaj yeem yog ib qho khoom siv sab hauv ntawm qee yam khoom siv thiab raug soldered rau hauv ib lub voj voog hybrid. Cov cuab yeej no yog qhov kawg txuas hauv txhua lub suab txhawb zog.
Lub zog amplifier tuaj yeem paub qhov txawv ntawm nws qhov chaw thov. Feem ntau muaj ob qhov tseem ceeb ntawm kev siv: hauv tsev thiab kev tshaj lij. Koj tuaj yeem faib lawv raws li cov phiaj xwm ua tiav rau hauv ib qho kawg thiab thawb-rub lub zog amplifiers. Ib lub voj voog ua haujlwm nyob rau hauv qhov hu ua linear amplification hom. Hauv hom no, tam sim no ntws los ntawm transistor rau tag nrho lub voj voog.
Lub zog amplifier muaj nyob rau hauv kiag li txhua yam khoom siv lossis cov khoom siv uas rov tsim cov suab nrov ntawm qhov dav tshaj plaws spectrum. Txij li cov teeb liab tseem ceeb uas tau nyeem thawj zaug feem ntau muaj lub zog tsis tseem ceeb, amplifiers yuav tsum tau siv los xa nws mus rau lwm yam khoom siv. Cov khoom siv zoo li no tuaj yeem pom hauv txhua lub xov tooj ntawm tes, lub kaw lus kaw lus, khoos phis tawj thiab khoos phis tawj, thiab txawm nyob hauv cov menyuam yaus cov khoom ua si uas tuaj yeem tham (uas muaj cov neeg hais lus). Hauv cov khoom siv hauv tsev zoo li no, cov khoom siv hauv tsev kuj tseem siv tau. Lub hom phiaj ntawm cov khoom siv no yog txhawm rau nthuav tawm cov teeb liab hluav taws xob rau qhov tseem ceeb ntawm lub suab ntau yam uas tib neeg lub pob ntseg tuaj yeem pom tau (feem ntau ntawm 15 txog 22 kilohertz). Nws yuav tsum raug sau tseg tias nrog lub hnub nyoog, qhov ntau ntawm qhov qis qis (nws qhov siab tshaj plaws feem ntau poob), kev hnov lus tsis zoo - thiab cov neeg laus feem ntau tsis tuaj yeem pom lub suab ntawm ntau dua 16-17 kilohertz.
Kev tshaj lij amplifiers tau siv dav hauv kev lag luam, piv txwv li, xws li cov khoom siv hluav taws xob tshaj tawm. Nws yog siv rau kev ceeb toom suab hauv cov tsev tswj hwm, cov chaw lag luam loj thiab qhib chaw, chaw ntau pob thiab chaw lom zem. Lawv lub hom phiaj yog txhawm rau nthuav dav thiab xa cov teeb liab suab rau kev tshaj tawm (xov tooj cua tshaj tawm) ntawm ntau qhov chaw loj.
Nyob zoo li nontaus ntawv, raws li lub hwj chim amplifier, yuav ua tau ntau haiv neeg thiab sib txawv heev nyob ntawm seb nws daim ntawv thov thiab lub hom phiaj. Tej zaum kuj yuav muaj qhov sib txawv tsim tshwj xeeb. Piv txwv li, lub tshuab hluav taws xob muaj suab nrov muaj qhov tshwj xeeb playback system, tiv thaiv dej thiab ya raws, thiab lub qhov cua mus tas li. Tag nrho cov no nyob rau hauv tag nrho muab lub sij hawm ntev ntawm kev ua hauj lwm ntawm lub suab-amplifying cov khoom nyob rau hauv tej yam kev mob ntawm siab tshaj loads.
