Rau qee qhov xwm txheej tseem ceeb lossis kev ua yeeb yam loj, cov niam txiv tshiab yuav tsum tau tsim ib theem thaum lawv tau sib yuav, thiab tom qab ua tiav theem, kev siv lub suab theem yog qhov tseem ceeb. Nrog rau cov lus txib ntawm lub suab theem, cov nyhuv theem tuaj yeem ua tau zoo dua. Txawm li cas los xij, theem suab tsis yog ib yam khoom siv. Lub suab nrov theem no feem ntau suav nrog cov cuab yeej hauv qab no.

1. Microphone

Microphones tuaj yeem hloov suab mus rau hauv cov teeb liab hluav taws xob. Qhov no electro-acoustic transducer yog ib qho ntawm ntau haiv neeg ntawm theem suab tshuab. Microphones yog kev taw qhia, thiab muaj ntau hom thiab cov duab ntawm microphones. Lawv cov qauv thiab kev siv kuj txawv. Yog li ntawd, cov theem sib txawv tuaj yeem xaiv cov microphones tsim nyog raws li qhov chaw ntawm qhov chaw.

2. Cov neeg hais lus

Cov neeg hais lus tuaj yeem hloov cov teeb liab hluav taws xob rau hauv cov suab paj nruag, thiab cov hom tseem ceeb muaj xws li hluav taws xob hluav taws xob, pneumatic, thiab piezoelectric ceramics. Lub thawv hais lus yog lub thawv hais lus, uas tuaj yeem muab tso rau hauv lub thawv. Nws yog ib qho khoom siv tseem ceeb rau kev nthuav qhia thiab txhawb cov ntses bass thaj tsam. Nws yog feem ntau muab faib ua cov neeg hais lus kaw thiab cov hais lus labyrinth, uas yog ob qho tseem ceeb ntawm cov suab nrov theem. .

3. Mixers thiab amplifiers

Tam sim no, muaj ntau lub suab nrov hauv tsev thiab ntau hom, ntawm cov khoom sib tov yog ib qho khoom siv tseem ceeb uas tsis tseem ceeb. Lub tov khoom muaj ntau cov channel inputs, thiab txhua channel tuaj yeem ua thiab ua cov suab ntawm nws tus kheej. Qhov no yog ntau lub suab sib xyaw ua ke thiab cov cuab yeej tseem ceeb rau cov kws tsim hluav taws xob tsim suab. Tsis tas li ntawd, vim li cas vim li cas lub suab theem muaj qhov sib kis tau ntev heev yog vim li cas lub zog amplifier ua lub luag haujlwm. Lub hwj chim amplifier tuaj yeem hloov lub suab hluav taws xob teeb liab mus rau lub zog teeb liab txhawm rau thawb tus neeg hais lus kom tawm suab. Yog li ntawd, lub hwj chim amplifier kuj yog ib feem tseem ceeb ntawm lub suab theem. .

Los ntawm peb qhov saum toj no, peb tuaj yeem paub tias hom khoom siv nrog rau theem suab yog qhov nplua nuj. Cov khoom siv suab nrov uas tau lees paub thiab nyiam los ntawm tib neeg, ua rau ntau tus neeg mus yuav cov khoom siv suab nrov loj.
