Mumazuva anoAudio masisitimu,amplifiers pasina mubvunzo ndechimwe chezvinhu zvakanyanya kukosha.Izvo hazvingokanganisa kunaka kweruzha, asi zvakare inotarisisa kuita kwese uye ruzivo rwemushandisi weiyo system.Chinyorwa ichi chichazeya mukati mezvinhu zvakakosha zvemagetsi amplifierskuti ikubatsire kunzwisisa kuti sei zvinhu izvi zvakakosha.
1. Simba rinobuda: Dhonza mwoyo wenyanga
Rimwe remabasa makuru eamplifier kupa simba rakakwana kutyaira mutauri.Simba rinobuda rinotarisa kana iyo audio system inogona kuchengetedza yakajeka uye isina kukanganiswa ruzha pamavhoriyamu akasiyana.Simba rinobuda remagetsi amplifier rinowanzoratidzwa mumawatts (W).Kusarudza iyo yakakodzera simba amplifier kunoda kufunga nezve anotevera mapoinzi:
Yakayerwa simba remutauri: Simba remutauriri rinofanira kuenderana neyakayerwa simba remutauri.Simba shoma rinogona kukonzera inzwi risina kukwana uye kukanganisa, asi simba rakawandisa rinogona kukuvadza mutauri.
Saizi yekamuri uye acoustic nharaunda: Mumakamuri mahombe kana nharaunda dzisina kusimba mutsindo, maamplifiers epamusoro anodiwa kuti ive nechokwadi chekuvharika kwakafanana uye kwakajeka.
Mhando yemimhanzi uye maitiro ekuteerera: Vashandisi vanonakidzwa nekuteerera kune yakakwirira simba renji mimhanzi vangada epamusoro emagetsi amplifiers kuchengetedza ruzivo uye simba remumhanzi pamavhoriyamu akakwira.
2. Kukanganisa: Muurayi asingaoneki wehutano hwenzwi
Kukanganisa ndechimwe chezviratidzo zvakakosha zvekuongorora kunaka kwemagetsi amplifiers.Inoreva chero shanduko dzisina kufanira muchiratidzo chekuisa panguva yekusimudza maitiro.Iko kune kunyanya kunotevera marudzi ekukanganiswa:
Harmonic distortion: Iyo frequency yakawanda inogadzirwa panguva yekusimudza chiratidzo.Kukanganiswa uku kunogona kuita kuti ruzha ruve rusiri rwechisikigo uye kukanganisa kunaka kweruzha.
Inter-modulation distortion: frequency nyowani inogadzirwa kana masaini emhando dzakasiyana akasanganiswa mune amplifier, izvo zvinogona kutungamira kune zvisingadiwe toni muodhiyo chiratidzo.
Trans-conductance distortion: Iyo isiri-mutsara hukama pakati pekubuda kwesimba amplifier uye chiratidzo chekuisa, chinowanzoitika panguva yekuremerwa.
Yakanakisa amplifier dhizaini inoderedza izvi kukanganisa uye inopa yakajeka uye yakasikwa ruzha rwemhando.
3. Frequency mhinduro: Kudzoreredza hupamhi nekudzika kwenzwi
Frequency mhinduro inoreva frequency renji iyo simba amplifier inogona kunyatso kusimudzira, inowanzo kuyerwa muHertz (Hz).Yakanaka amplifier inofanirwa kupa yakapfava uye yakafanana amplifier mukati mese audio spectrum (kazhinji kubva pa20Hz kusvika 20kHz).Chiyero chefrequency response chinokanganisa zvakananga kudzoreredza mhedzisiro yekurira:
Yakaderera frequency mhinduro: inokanganisa kudzika uye kukanganisa kweiyo bass.Amplifiers ane yakanaka yakaderera-frequency mhinduro inogona kupa yakasimba bass mhedzisiro.
Mid frequency mhinduro: inonyanya kukanganisa mashandiro ezwi uye zviridzwa, uye ndicho chikamu chepakati chemhando yekurira.
Yakakwira frequency mhinduro: Inokanganisa kujeka uye kuita kweruzivo rwemanotsi epamusoro, uye amplifier yemagetsi ine yakanaka yakakwira frequency mhinduro inogona kuita kuti ruzha ruve pachena uye rwechokwadi.
4. Chiratidzo kune ruzha reshiyo (SNR): vimbiso yemhando yakachena yeruzha
Chiratidzo kuNoise Ratio chiratidzo chinoyera reshiyo pakati pechiratidzo chinobatsira uye ruzha mune inobuda chiratidzo chemagetsi amplifier, anowanzo kuratidzwa mumadecibel (dB).Yakakwira chiratidzo-kune-ruzha reshiyo zvinoreva kuti iyo amplifier yesimba inoburitsa shoma yekumashure ruzha kana ichikwiridzira chiratidzo, ichiva nechokwadi chekuchena kwemhando yekurira.Kusarudza amplifier yemagetsi ine yakakwira chiratidzo-kune-ruzha reshiyo inogona kuderedza kukanganiswa kwekunzwa uye kupa inonyudza yekuteerera ruzivo.
5. Circuit design yemagetsi amplifiers: ibwe rekona rekutsunga kwekuita
Iyo yemukati dhizaini dhizaini yesimba amplifier inokanganisa zvakananga kuita kwayo uye ruzha rwemhando.Kune akati wandei akajairika madhizaini edunhu:
Kirasi A amplifier: Iine yakanakisa ruzha mhando asi yakaderera zvakanyanya, inokodzera yepamusoro-yekupedzisira maodhiyo masisitimu anoteedzera yekupedzisira mhando yekurira.
Kirasi B amplifier: Kushanda kwakanyanya asi kwakakosha kukanganisa, kunowanzo shandiswa pakati kusvika yakaderera-yekupedzisira maodhiyo masisitimu.
Kirasi AB amplifier: Inosanganisa zvakanakira ese ari maviri Kirasi A uye Kirasi B, ine hunyanzvi hwepamusoro uye yakanaka ruzha rwemhando, uye parizvino ndiyo dhizaini yeamplifier.
Kirasi D amplifier: Nehunyanzvi hwepamusoro uye saizi diki, inokodzera michina inotakurika uye yemazuva ano imba yemitambo masisitimu.
Yese yedunhu dhizaini ine zvayakanakira nezvayakaipira, uye kusarudza mhando yeamplifier inoenderana nezvido zvako kwakakosha.
6. Mabasa uye kupindirana kwemagetsi amplifiers: kusangana nezvinodiwa zvakasiyana
Mazuva ano amplifiers haangode yakanakisa ruzha rwemhando, asi zvakare inoda kupa akapfuma mabasa uye ma interfaces kuti aenderane neakasiyana mashandisiro mamiriro.Semuyenzaniso:
Mazhinji ekuisa mainterface, akadai seRCA, fiber optic, coaxial, HDMI, nezvimwewo, fambisa kubatana kweakasiyana odhiyo sosi zvishandiso.
Wireless yekubatanidza: seBluetooth neWi Fi, yakanakira kubatanidzwa nenharembozha uyesmart home systems.
Multi chiteshi rutsigiro: yakakodzerahome theatre systems, ichipa ruzivo rwakanyanya kunyudza.
Kusarudza yakanakisa amplifier kunoda kutarisisa kwakadzama kwezvinhu zvakaita sekubuda kwesimba, kukanganisa, frequency mhinduro, chiratidzo-ku-ruzha reshiyo, dhizaini dhizaini, mashandiro, uye nzvimbo dzepakati.Nenzira iyi chete tinogona kuve nechokwadi chekuita kwakanyanya uye ruzivo rwemushandisi rweodhiyo system.Kunyangwe iwe uri anofarira mimhanzi kana anofarira theatre yepamba, kunzwisisa uye kuterera kune izvi zvakakosha zvinhu zvinokubatsira kusarudza mudziyo weamplifier unonyatso kuenderana newe, zvichiita kuti chiitiko chese chekuteerera chinakidze.
