Taw qhia
Lub suab amplifier yog ib qho khoom siv uas rov tsim kho cov teeb liab tawm suab ntawm cov khoom tso tawm uas ua suab nrov, thiab qhov tshwm sim ntawm cov teeb liab ntim thiab lub zog theem yog qhov zoo tagnrho-qhov tseeb, muaj txiaj ntsig, thiab tsis muaj kev cuam tshuam tsawg.Lub suab ntau yog hais txog 20Hz txog 20000Hz, yog li lub amplifier yuav tsum muaj cov lus teb zoo nyob rau hauv qhov ntau no (tsawg dua thaum tsav tsheb cov neeg hais lus txwv, xws li woofers lossis tweeters).Nyob ntawm daim ntawv thov, lub zog loj sib txawv heev, los ntawm milliwatts ntawm lub mloog pob ntseg mus rau ob peb watts ntawm TV lossis PC suab, mus rau kaum tawm watts ntawm "mini" lub suab hauv tsev thiab lub tsheb suab, mus txog ntau pua watts ntawm ntau lub zog hauv tsev thiab kev lag luam. suab tshuab, loj txaus kom tau raws li lub suab xav tau ntawm tag nrho cov xinesmas lossis auditorium.
Lub suab amplifiers yog ib qho tseem ceeb ntawm cov khoom lag luam multimedia thiab tau siv dav hauv cov khoom siv hluav taws xob.Linear audio amplifiers tau ua tus thawj coj hauv kev lag luam suab nrov nrov vim lawv qhov txawv me me thiab lub suab zoo.Nyob rau hauv xyoo tas los no, nrog cov koob nrov ntawm portable multimedia pab kiag li lawm xws li MP3, PDA, xov tooj ntawm tes, thiab phau ntawv computers, efficiency thiab ntim ntawm linear hwj chim amplifiers tsis tau raws li qhov yuav tsum tau ntawm kev ua lag luam, thiab chav kawm ntawv D lub hwj chim amplifiers yog nce siab nyiam. los ntawm cov neeg nrog lawv qhov zoo ntawm kev ua haujlwm siab thiab me me.Yog li ntawd, kev ua tau zoo ntawm Class D amplifiers muaj qhov tseem ceeb heev ntawm daim ntawv thov nqi thiab kev cia siab rau kev lag luam.
Txoj kev loj hlob ntawm lub suab amplifiers tau dhau los ntawm peb lub sijhawm: electron tubes (vacuum tubes), bipolar transistors, thiab field-effect transistors.Tube audio amplifier muaj lub suab sib npaug, tab sis nws yog qhov loj, kev siv hluav taws xob siab, kev ua haujlwm tsis ruaj khov, thiab cov lus teb tsis zoo;Bipolar transistor audio amplifier zaus bandwidth, loj dynamic ntau, muaj kev ntseeg siab, lub neej ntev, thiab cov lus teb zoo heev, tab sis nws cov khoom siv hluav taws xob zoo li qub, kev tiv thaiv yog loj heev, kev ua tau zoo yog qhov nyuaj rau kev txhim kho;FET audio amplifiers muaj tib lub suab sib npaug li cov raj, qhov dav dav dav, thiab qhov tseem ceeb tshaj, qhov me me ntawm kev ua haujlwm uas tuaj yeem ua tiav kev ua haujlwm siab.
Kev sib xyaw ua ke
Lub hom phiaj ntawm lub suab amplification yog los tsim cov suab input teeb liab ntawm qhov yuav tsum tau ntim thiab lub hwj chim theem ntawm lub suab tso zis lub caij nrog high efficiency thiab tsawg distortion.Qhov ntau zaus ntawm lub suab teeb liab yog 20Hz txog 20000Hz, yog li lub suab amplifier yuav tsum muaj cov lus teb zoo.Lub suab amplifiers feem ntau muaj xws li preamplifier thiab lub zog amplifier.
Preamplifier
Lub amplitude ntawm lub suab teeb liab qhov teeb liab feem ntau me me thiab tsis tuaj yeem ncaj qha tsav lub hwj chim amplifier, yog li lawv yuav tsum xub ua kom nrov rau qee qhov amplitude, uas yuav tsum tau siv lub preamplifier.Ntxiv nrog rau cov teeb liab amplification, lub preamplifier kuj tseem muaj cov haujlwm xws li kev hloov ntim, suab tswj, suab nrov, thiab kev sib npaug ntawm cov channel.
Lub zog amplifier
Lub hwj chim amplifiers raug xa mus rau lub hwj chim amplifiers, thiab lawv lub hom phiaj yog los muab lub peev xwm tsav tam sim no txaus rau lub nra kom ua tiav lub zog amplification.Class D amplifier ua haujlwm nyob rau hauv lub xeev hloov, theoretically nws tsis xav tau quiescent tam sim no, thiab muaj ib tug high efficiency.
