Suab Active thiab Passive

Active suab division tseem hu ua active zaus division.Nws yog hais tias lub suab teeb liab ntawm tus tswv tau muab faib rau hauv lub hauv paus ua haujlwm ntawm tus tswv tsev ua ntej yuav tsum tau amplified los ntawm lub hwj chim amplifier circuit.Lub hauv paus ntsiab lus yog hais tias lub suab teeb liab raug xa mus rau lub hauv paus ua haujlwm chav tsev (CPU) ntawm tus tswv, thiab lub hauv paus ua haujlwm ntawm tus tswv tsev lub teeb liab tau muab faib ua cov teeb liab tsawg zaus thiab cov teeb liab ntau zaus raws li cov lus teb ntau zaus, thiab tom qab ntawd ob lub teeb liab sib cais tau nkag mus rau hauv amplifying circuit thiab amplified cais.Txoj kev faib zaus yog digital.

Passive sound division, tseem hu ua passive zaus division, nws yog hais tias lub suab teeb liab yog amplified los ntawm lub hwj chim amplifier Circuit Court thiab ces muab faib los ntawm passive crossover, thiab ces input mus rau coj tweeter los yog woofer.Lub hauv paus ntsiab lus yog tias lub suab nrov zaus yog lim tawm los ntawm inductance Circuit Court, tawm hauv lub suab qis, thiab tom qab ntawd nkag mus rau lub suab qis rau woofer.Lub suab qis qis yog lim tawm los ntawm electrolytic capacitor thiab lub suab nrov zaus sab laug, thiab tom qab ntawd nws nkag mus rau lub tweeter.Txoj kev faib zaus yog hloov kho los ntawm qhov hloov pauv hloov tau.

Suab Active thiab Passive

Active suab faib yuav tsum yog lub ntsiab chav tsev nrog active zaus division muaj nuj nqi los yog ntxiv ib tug digital active crossover tom qab lub suab tso zis ntawm lub ntsiab unit.Feem ntau, cov qauv high-end ntawm Alpine lub ntsiab chav tsev muaj cov nquag faib ua haujlwm.Nws yog tus cwj pwm los ntawm qhov tseeb crossover cov ntsiab lus thiab kev faib zaus.Lub suab yog huv si tom qab sib faib zaus.

Lub suab nrov nrov tau siv los ntawm ntau tus neeg.Lub suab nrov me me ntawm Walkman yog cov neeg hais lus nrov nrov, uas yog, ib pawg ntawm amplifiers tau ntxiv rau lub thawv nrov nrov.Thaum peb xav siv nws, peb tsuas xav tau pem hauv ntej theem thiab tsis yog theem tom qab.Lub zog sab hauv siv txoj kev faib suab hluav taws xob, thiab tshem tawm cov teeb meem ntawm kev sib txuam nrog cov theem tom qab tsim nyog;passive loudspeaker yog lub suab nrov dav dav nrog tsuas yog ib qho kev sib txuas hauv network.

Lub active pem hauv ntej theem yog pem hauv ntej theem ntawm IC, transistor, thiab lub tshuab nqus tsev raj uas peb feem ntau pom.Nws muaj cov nyhuv amplifying thaum lub teeb liab yog input thiab ces tso zis.Hom ntawm pem hauv ntej theem no tuaj yeem ua haujlwm siab ua haujlwm zoo, thiab cov yam ntxwv ntawm txhua tus qauv kuj txawv ntawm timbre.Lub passive pem hauv ntej theem yog tsuas yog ib tug ntim tswj attenuator, nws cov zis yuav me dua lub input, tab sis lub suab rendering teeb meem yog tsawg, feem ntau tsuas yog ib tug me ntsis txawv, tsis zoo li lub active pem hauv ntej amplifier yog txawv heev.
