Lub Cheebtsam ntawm lub suab tuaj yeem muab faib ua qhov sib txawv ntawm lub suab (lub teeb liab qhov chaw) ib feem, lub zog amplifier thiab cov hais lus los ntawm cov khoom siv.

Lub hauv paus: Lub suab yog qhov chaw ntawm lub kaw lus, qhov kawg ntawm tus neeg hais lus los ntawm.Cov khoom siv suab nrov yog: CD player, LP vinyl player, digital player, xov tooj cua tuners thiab lwm yam khoom siv suab.Cov khoom siv no hloov lossis demodulate audio signals nyob rau hauv chaw cia khoom lossis xov tooj cua hauv lub suab analog teeb liab los ntawm kev hloov pauv digital-rau-analog lossis demodulation tso zis.

Fais fab amplifier: Lub zog amplifier tuaj yeem muab faib ua pem hauv ntej-theem thiab nram qab-theem.Lub hauv ntej-theem preprocesses lub teeb liab los ntawm lub suab qhov chaw, suav nrog tab sis tsis txwv rau kev hloov cov tswv yim, ua ntej amplification, lub suab hloov thiab lwm yam haujlwm.Nws lub hom phiaj tseem ceeb yog ua kom cov zis impedance ntawm lub suab thiab cov input impedance ntawm lub rear theem yog matched los txo distortion, tab sis lub pem hauv ntej theem tsis yog ib tug kiag li tsim nyog txuas.Cov theem tom qab yog txhawm rau ua kom lub zog ntawm cov teeb liab tso tawm los ntawm theem pem hauv ntej lossis lub suab nrov los tsav lub suab nrov kom tawm suab.

Loudspeaker (hais lus): Cov tsav tsheb ntawm lub suab nrov yog lub tshuab hluav taws xob-acoustic transducer, thiab tag nrho cov teeb liab ua qhov kawg yog npaj rau kev txhawb nqa lub suab nrov.Lub zog-amplified suab teeb liab txav daim ntawv lub khob hliav qab los yog diaphragm los ntawm electromagnetic, piezoelectric los yog electrostatic los tsav cov huab cua nyob ib puag ncig kom ua suab.Tus hais lus yog lub davhlau ya nyob twg ntawm tag nrho lub suab kaw lus.
