Nhanganyaya
An odhiyo amplifier chishandiso chinovaka patsva yekuisa odhiyo siginecha pane inobuda chinhu chinoburitsa ruzha, uye inokonzeresa vhoriyamu yechiratidzo uye nhanho yemagetsi yakanaka-ichokwadi, inoshanda, uye yakaderera kukanganisa.Iro redhiyo renji rinenge 20Hz kusvika 20000Hz, saka amplifier inofanirwa kunge iine yakanaka frequency mhinduro mukati meiyi renji (idiki kana uchityaira mabhendi-akamanikidza vatauri, vakaita sewoofers kana tweeters).Zvichienderana nekushandiswa, saizi yesimba inosiyana zvakanyanya, kubva pamamilliwatts ehedhifoni kusvika kune akati wandei watts eTV kana PC odhiyo, kusvika kune gumi nemaviri ewatts e "mini" stereo yekumba uye odhiyo yemotokari, kusvika kumazana emawatts emamwe ane simba epamba uye ekutengesa. masisitimu ekurira, akakura zvakakwana kuti asangane nezvinodiwa zvemabhaisikopo kana odhitoriyamu yese.
Audio amplifiers chimwe chezvinhu zvakakosha zvezvigadzirwa zvemultimedia uye zvinoshandiswa zvakanyanya mumunda wemagetsi evatengi.Linear odhiyo amplifiers anga achitonga mumusika wetsika odhiyo amplifier nekuda kwekukanganisa kwavo kudiki uye yakanaka ruzha rwemhando.Mumakore achangopfuura, nekufarirwa kwemidziyo inotakurika yemultimedia yakadai seMP3, PDA, nharembozha, uye makomputa ekunyorera, kushanda nesimba uye huwandu hwemagetsi emagetsi amplifiers haachakwanise kuzadzisa zvinodiwa pamusika, uye kirasi D magetsi amplifiers ari kuwedzera kufarirwa. nevanhu vane mabhenefiti avo ehunyanzvi hwepamusoro uye hukuru hudiki.Naizvozvo, yepamusoro-inoshanda Kirasi D amplifiers ane yakakosha kukosha kwekushandisa uye musika tarisiro.
Kuvandudzwa kwemaodhiyo amplifiers kwapfuura nguva nhatu: erekitironi machubhu (vacuum chubhu), bipolar transistors, uye munda-effect transistors.Tube odhiyo amplifier ine toni yakatenderedzwa, asi yakakura, yakakwira simba rekushandisa, yakanyanya kusagadzikana kushanda, uye yakashata yakakwirira frequency mhinduro;Bipolar transistor odhiyo amplifier frequency bandwidth, yakakura simba renji, kuvimbika kwepamusoro, hupenyu hurefu, uye yakanaka yakakwirira frequency mhinduro, asi yayo static mashandisiro emagetsi, pa-kupikisa yakakura kwazvo, kushanda nesimba kwakaoma kuvandudza;FET odhiyo amplifiers ine yakafanana yakatenderedzwa toni semachubhu, yakafara dhizaini, uye zvakatonyanya kukosha, diki pa-kupokana iyo inogona kuita yakanyanya kushanda.
Maumbirwo Ezvakaita
Chinangwa chekusimudzira odhiyo ndechekuburitsa chiratidzo chekuisa odhiyo pane inodiwa vhoriyamu uye nhanho yesimba pane inonzwika inobuda chinhu nehunyanzvi hwepamusoro uye kushomeka kwakaderera.Iyo frequency renji yeaudio siginecha ndeye 20Hz kusvika 20000Hz, saka odhiyo amplifier inofanira kuva yakanaka frequency mhinduro.Audio amplifiers inowanzo sanganisira preamplifier uye simba amplifier.
Preamplifier
Iyo amplitude yeodhiyo chiratidzo sosi siginecha kazhinji idiki kwazvo uye haigone kutyaira yakananga magetsi amplifier, saka ivo vanofanirwa kutanga vakwidziridzwa kune imwe amplitude, inoda kushandiswa kwepreamplifier.Pamusoro pekuwedzera kwechiratidzo, iyo preamplifier inogona zvakare kuita senge vhoriyamu gadziriso, pitch control, ruzha kutonga, uye chiteshi kuenzana.
Simba amplifier
Masimba amplifiers anonzi emagetsi amplifiers, uye chinangwa chavo ndechekupa yakakwana ikozvino dhiraivha kugona kumutoro kuti uwane simba rekusimudzira.Iyo Kirasi D amplifier inoshanda mukuchinja mamiriro, theoretically haidi quiescent ikozvino, uye ine yakakwirira kunyatsoshanda.
