Izingxenye zomsindo zingahlukaniswa cishe zibe yingxenye yomthombo womsindo (umthombo wesignali), ingxenye ye-power amplifier kanye nengxenye yesipikha kusuka kuhadiwe.

Umthombo womsindo: Umthombo womsindo uyingxenye yomthombo wesistimu yomsindo, lapho umsindo wokugcina wesipikha uvela khona. Imithombo evamile yomsindo yile: abadlali be-CD, abadlali be-LP vinyl, abadlali bedijithali, ama-tuner omsakazo kanye namanye amadivayisi okudlala umsindo. Lawa madivayisi aguqula noma ahlukanise amasignali omsindo kwimidiya yokugcina noma eziteshini zomsakazo abe amasignali e-analog omsindo ngokuguqulwa kwedijithali kuya ku-analog noma ukukhipha i-demodulation.

I-Power amplifier: I-power amplifier ingahlukaniswa ibe yisigaba sangaphambili nesigaba sangemuva. Isigaba sangaphambili sicubungula isignali evela emthonjeni womsindo, okuhlanganisa kodwa kungagcini ngokushintshwa kokufaka, ukukhulisa kokuqala, ukulungiswa kwethoni neminye imisebenzi. Inhloso yaso eyinhloko ukwenza ukuvimba kokukhipha komthombo womsindo kanye nokuvimba kokufaka kwesigaba sangemuva kufaniswe ukunciphisa ukuhlanekezela, kodwa isigaba sangaphambili asiyona isixhumanisi esidingekayo ngokuphelele. Isigaba sangemuva ukukhulisa amandla okukhipha isignali yisigaba sangaphambili noma umthombo womsindo ukushayela uhlelo lwe-loudspeaker ukuze lukhiphe umsindo.

Isandisi-zwi (isikhulumi): Amayunithi omshayeli wesipikha ayi-transducer ye-electro-acoustic, futhi zonke izingxenye zokucubungula isignali ekugcineni zilungiselelwe ukukhuthazwa kwesipikha. Isignali yomsindo ekhuliswe ngamandla ihambisa ikhoni yephepha noma i-diaphragm ngemiphumela ye-electromagnetic, piezoelectric noma electrostatic ukuze ishayele umoya ozungezile ukuze wenze umsindo. Isipikha siyisiphelo sesistimu yomsindo yonke.
