Izingxenye zomsindo zingahlukaniswa cishe zibe ingxenye yomthombo womsindo (umthombo wesiginali), ingxenye yesikhulisamandla kanye nengxenye yesipika evela kuhadiwe.

Umthombo womsindo: Umthombo womsindo uyingxenye yomthombo wesistimu yomsindo, lapho umsindo wokugcina wesipika uvela khona.Imithombo yomsindo evamile yilena: Izidlali ze-CD, izidlali ze-LP vinyl, izidlali zedijithali, izishuna zomsakazo nezinye izinto zokudlala ezilalelwayo.Lawa madivaysi aguqula noma ehlise amasiginali omsindo kumidiya yesitoreji noma eziteshini zomsakazo zibe amasignali e-analog yomsindo ngokuguqulwa kwedijithali-kuya-analogi noma okukhiphayo kokudilizwa.

Isikhulisi samandla: Isikhulisi samandla singahlukaniswa sibe yisiteji sangaphambili nangemuva.Isiteji esingaphambili sicubungula isiginali evela emthonjeni womsindo, okuhlanganisa kodwa kungagcini nje ngokushintsha okokufaka, ukukhulisa isandiso sokuqala, ukulungisa ithoni neminye imisebenzi.Inhloso yayo eyinhloko ukwenza ukuthikamezeka kokukhiphayo komthombo womsindo kanye nokuthikamezeka kokufaka kwesiteji esingemuva kufaniswe ukuze kuncishiswe ukuhlanekezela, kodwa isigaba esingaphambili akusona isixhumanisi esidingekayo.Isiteji esingemuva esokukhulisa amandla okukhipha isignali ngesiteji esingaphambili noma ngomthombo womsindo ukushayela isistimu yesipikha ukuze ikhiphe umsindo.

Isipikha (isipikha): Amayunithi omshayeli wesipikha i-electro-acoustic transducer, futhi zonke izingxenye zokucubungula isignali ekugcineni zilungiselelwa ukuphromothwa kwesipikha.Isignali yomsindo ekhuliswe amandla ihambisa ikhoni yephepha noma i-diaphragm ngokusebenzisa i-electromagnetic, piezoelectric noma imiphumela ye-electrostatic ukushayela umoya ozungezile ukuze wenze umsindo.Isipika siyitheminali yalo lonke uhlelo lomsindo.
