Mawu Oyamba
Chokulitsa mawu ndi chipangizo chomwe chimamanganso siginecha yolowera pachotulutsa chomwe chimatulutsa mawu, ndipo kuchuluka kwa siginecha ndi gawo lamagetsi ndizoyenera - zowona, zogwira mtima, komanso zosokoneza pang'ono.Mtundu wamawu ndi pafupifupi 20Hz mpaka 20000Hz, kotero chokulitsa chimayenera kukhala ndi kuyankha kwafupipafupi mkati mwamtunduwu (ocheperako poyendetsa ma speaker omwe ali ndi gulu, monga ma woofer kapena ma tweeters).Kutengera ndikugwiritsa ntchito, kukula kwa mphamvu kumasiyanasiyana kwambiri, kuyambira ma milliwatt a mahedifoni kupita ku ma watt angapo a TV kapena ma audio a PC, mpaka ma Watts ambiri a "mini" stereo yakunyumba ndi zomvera zamagalimoto, mpaka mazana a Watts amphamvu kwambiri apakhomo ndi amalonda. makina amawu, okulirapo mokwanira kuti akwaniritse zomveka za kanema wathunthu kapena holo.
Ma audio amplifiers ndi chimodzi mwazinthu zofunika kwambiri pazambiri zamawu ndipo amagwiritsidwa ntchito kwambiri pamagetsi ogula.Ma linear audio amplifiers akhala akuchulukirachulukira pamsika wamawu amplifier chifukwa chakusokonekera kwawo pang'ono komanso kumveka bwino kwamawu.M'zaka zaposachedwa, chifukwa cha kutchuka kwa zida zonyamulika zama multimedia monga MP3, PDA, mafoni am'manja, ndi makompyuta apakompyuta, mphamvu komanso kuchuluka kwa zokulitsa mphamvu zama mzere sikungathenso kukwaniritsa zofunikira pamsika, ndipo zokulitsa mphamvu za gulu la D zikukondedwa kwambiri. ndi anthu ndi ubwino wawo mkulu dzuwa ndi yaing'ono kukula.Chifukwa chake, ma amplifiers apamwamba kwambiri a Class D ali ndi mtengo wofunikira kwambiri komanso chiyembekezo chamsika.
Kupanga zokulitsa mawu kwadutsa nthawi zitatu: ma electron chubu (vacuum chubu), bipolar transistors, ndi ma transistors amtundu.Tube audio amplifier imakhala ndi kamvekedwe kozungulira, koma ndi yayikulu, imagwiritsa ntchito mphamvu zambiri, imagwira ntchito yosakhazikika, komanso kuyankha kosakwanira;Bipolar transistor audio amplifier frequency bandwidth, yayikulu yosinthika, kudalirika kwakukulu, moyo wautali, komanso kuyankha kwapafupipafupi, koma kugwiritsa ntchito mphamvu zake zosasunthika, kukana ndi zazikulu kwambiri, kuchita bwino ndikovuta kuwongolera;Ma audio amplifiers a FET ali ndi kamvekedwe kozungulira ngati machubu, mawonekedwe osiyanasiyana, ndipo koposa zonse, kukana pang'ono komwe kumatha kuchita bwino kwambiri.
Mapangidwe Apangidwe
Cholinga cha kukulitsa mawu ndikutulutsanso siginecha yolowetsa mawu pa voliyumu yofunikira ndi mulingo wa mphamvu pa chinthu chotulutsa mawu ndikuchita bwino kwambiri komanso kusokoneza pang'ono.Mafupipafupi amtundu wa siginecha yamawu ndi 20Hz mpaka 20000Hz, kotero amplifier yomvera iyenera kuyankha bwino pafupipafupi.Ma audio amplifier nthawi zambiri amakhala ndi preamplifier ndi amplifier mphamvu.
Preamplifier
Kukula kwa siginecha yoyambira siginecha nthawi zambiri kumakhala kochepa kwambiri ndipo sikungayendetse mwachindunji amplifier yamagetsi, chifukwa chake iyenera kukulitsidwa kaye kumtunda wina, womwe umafunikira kugwiritsa ntchito preamplifier.Kuphatikiza pa kukulitsa ma siginecha, preamplifier imathanso kukhala ndi ntchito monga kusintha kwa voliyumu, kuwongolera mamvekedwe, kuwongolera mokweza, komanso kufananiza kwachanelo.
Mphamvu amplifier
Ma amplifiers amatchulidwa kuti amplifiers mphamvu, ndipo cholinga chawo ndikupereka mphamvu zokwanira pakali pano pagalimoto kuti akwaniritse kukulitsa mphamvu.Class D amplifier imagwira ntchito posintha, mwachidziwitso sichifuna quiescent pano, ndipo imakhala yogwira ntchito kwambiri.
