Intshayelelo
Isandisi somsindo sisixhobo esakha kwakhona isignali yomsindo igalelo kwinto ephumayo evelisa isandi, kunye nesiphumo somthamo wesiginali kunye nenqanaba lamandla lifanelekile-linyanisekile, lisebenzayo, kwaye liphantsi.Uluhlu lwe-audio malunga ne-20Hz ukuya kwi-20000Hz, ngoko ke i-amplifier kufuneka ibe nempendulo efanelekileyo yefrikhwensi ngaphakathi kolu luhlu (incinci xa uqhuba izithethi ze-band-constrained, ezifana ne-woofers okanye i-tweeters).Kuxhomekeka kwisicelo, ubungakanani bamandla buhluka kakhulu, ukusuka kwi-milliwatts yee-headphones ukuya kwiiwatts ezininzi zeTV okanye zePC, ukuya kwishumi leewatts "mini" yestereo yasekhaya kunye neaudio yemoto, ukuya kuthi ga kumakhulu eewatts ezinamandla ngakumbi asekhaya kunye nezorhwebo. iinkqubo zesandi, ezinkulu ngokwaneleyo ukuhlangabezana neemfuno zesandi se-cinema epheleleyo okanye iholo.
Izandisi zomsindo yenye yezona zinto zibalulekileyo kwiimveliso zemultimedia kwaye zisetyenziswa kakhulu kwindawo yomthengi wombane.Izandisi zomsindo ezilayini ziye zalawula kwimakethi yemveli yeamplifier yomsindo ngenxa yokugqwetheka kwabo okuncinci kunye nomgangatho olungileyo wesandi.Kwiminyaka yakutshanje, ngokuduma kwezixhobo zemultimedia eziphathwayo ezinje ngeMP3, PDA, iiselfowuni, kunye nekhompyuter yencwadana yamanqaku, ukusebenza kakuhle kunye nomthamo wesandisi-mandla esisemgceni akusakwazi ukuhlangabezana neemfuno zentengiso, kwaye izandisi zamandla zeklasi D ziya zithandwa. ngabantu abaneenzuzo zabo zokusebenza okuphezulu kunye nobukhulu obuncinci.Ke ngoko, iiamplifiers zeKlasi D ezisebenza kakhulu zinexabiso elibaluleke kakhulu lesicelo kunye nethemba lentengiso.
Ukuphuhliswa kwe-audio amplifiers kuye kwadlula amaxesha amathathu: iityhubhu ze-electron (i-vacuum tubes), i-bipolar transistors, kunye ne-field-effect transistors.I-Tube yeamplifier yomsindo inethowuni engqukuva, kodwa inkulu, isetyenziswa kakhulu amandla, intsebenzo engazinzanga kakhulu, kunye nokungaphenduli kakuhle kwamaza;I-Bipolar transistor audio amplifier frequency bandwidth, uluhlu olukhulu oluguquguqukayo, ukuthembeka okuphezulu, ubomi obude, kunye nempendulo elungileyo yefrikhwensi, kodwa ukusetyenziswa kwayo kwamandla angatshintshiyo, ukuxhathisa kukhulu kakhulu, ukusebenza kakuhle kunzima ukuphucula;Izandisi zomsindo we-FET zinethowuni engqukuva efanayo njengeityhubhu, uluhlu oluguquguqukayo olubanzi, kwaye okona kubaluleke kakhulu, ukuxhathisa okuncinci okunokuthi kufikelele ekusebenzeni okuphezulu.
Ukubunjwa koLwakhiwo
Injongo yokukhulisa umsindo kukuvelisa kwakhona isandi somsindo kwivolumu efunekayo kunye nenqanaba lamandla kwisixhobo sokuphuma kwesandi kunye nokusebenza okuphezulu kunye nokuphazamiseka okuphantsi.Uluhlu lwamaza omsindo luyi-20Hz ukuya kwi-20000Hz, ngoko ke iamplifier yomsindo kufuneka ibe nempendulo elungileyo.Izandisi zomsindo ngokuqhelekileyo ziquka i-preamplifier kunye ne-amplifier yamandla.
Isamplifier
I-amplitude yesignali yomthombo womsindo incinci kakhulu kwaye ayikwazi ukuqhuba ngokuthe ngqo i-amplifier yamandla, ngoko ke kufuneka iqale yandiswe kwi-amplitude ethile, efuna ukusetyenziswa kwe-preamplifier.Ukongeza kulwandiso lomqondiso, i-preamplifier inokuba nemisebenzi efana nohlengahlengiso lwevolumu, ulawulo lwesandi, ulawulo lwesandi esiphakamileyo, kunye nokulingana kwetshaneli.
I-amplifier yamandla
I-amplifiers yamandla ibhekiselwa kuzo njengezandisi zamandla, kwaye injongo yazo kukubonelela ngesakhono esaneleyo sokuqhuba ngoku kumthwalo ukufezekisa ukukhulisa amandla.I-amplifier ye-Class D isebenza kwimeko yokutshintsha, ithiyori ayifuni i-quiescent current, kwaye inokusebenza okuphezulu.
