Rau qee qhov xwm txheej tseem ceeb lossis kev ua yeeb yam loj, cov neeg tshiab yuav tsum tsim ib lub sam thiaj thaum lawv sib yuav, thiab tom qab ua tiav lub sam thiaj lawm, kev siv lub suab ntawm lub sam thiaj yog qhov tseem ceeb. Nrog kev hais kom ua lub suab ntawm lub sam thiaj, qhov cuam tshuam ntawm lub sam thiaj tuaj yeem ua kom zoo dua. Txawm li cas los xij, lub suab ntawm lub sam thiaj tsis yog ib hom khoom siv. Lub suab ntawm lub sam thiaj dav dav no feem ntau suav nrog cov khoom siv hauv qab no.

1. Lub microphone

Cov microphones muaj peev xwm hloov suab mus ua cov teeb liab hluav taws xob. Lub transducer electro-acoustic no yog ib qho ntawm ntau hom suab nrov tshaj plaws. Cov microphones yog cov kev taw qhia, thiab muaj ntau hom thiab cov duab ntawm cov microphones. Lawv cov qauv thiab kev siv kuj txawv. Yog li ntawd, ntau theem tuaj yeem xaiv cov microphones tsim nyog raws li qhov ntau thiab tsawg ntawm qhov chaw.

2. Cov neeg hais lus

Cov neeg hais lus tuaj yeem hloov cov teeb liab hluav taws xob mus rau hauv cov teeb liab suab, thiab cov hom tseem ceeb suav nrog hluav taws xob hluav taws xob, pneumatic, thiab piezoelectric ceramics. Lub thawv hais lus yog lub thawv ntawm tus neeg hais lus, uas tuaj yeem muab tso rau hauv lub thawv. Nws yog lub cuab yeej tseem ceeb rau kev tso saib thiab nplua nuj lub bass. Nws feem ntau yog muab faib ua cov neeg hais lus kaw thiab cov neeg hais lus labyrinth, uas yog ob qho tseem ceeb ntawm lub suab theem. .

3. Cov khoom sib tov thiab cov amplifiers

Tam sim no, muaj ntau lub npe nrov hauv tsev thiab ntau hom, ntawm cov khoom siv sib tov yog qhov tseem ceeb tshaj plaws. Lub mixer muaj ntau lub channel inputs, thiab txhua channel tuaj yeem ua thiab ua cov suab ntawm nws tus kheej. Qhov no yog ntau lub cuab yeej sib tov suab thiab yog ib qho tseem ceeb rau cov kws ua suab los tsim suab. Tsis tas li ntawd, qhov laj thawj vim li cas lub suab theem muaj qhov sib kis ntev yog vim lub zog amplifier ua lub luag haujlwm. Lub zog amplifier tuaj yeem hloov lub teeb liab hluav taws xob suab mus rau hauv lub teeb liab hluav taws xob kom thawb lub hais lus kom tso suab. Yog li ntawd, lub zog amplifier kuj yog ib feem tseem ceeb ntawm lub suab theem. .

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