Mbiri ya kudzera m'zokuzira mawu

A dongosolo Makaniko, kulankhula, kapena kuyankhula ndi transducer electromechanical kuti otembenuka ndi chizindikiro magetsi. Mawu akuti Makaniko angatanthauze chipangizo munthu kapena dalaivala, ndi lathunthu zochitika wopangidwa ndi mpanda corporating chimodzi kapena zingapo madalaivala ndi zamagetsi zina.

Kudzera m'zokuzira mawu ndi zinthu zambiri variable mu dongosolo lililonse zomvetsera, ndipo ali ndi udindo amalembedwa kusiyana lomveka pakati pa machitidwe mwinamwake zofanana phokoso. Makaniko ntchito kapena zolondola kubereka mbendera popanda kuwonjezera kupotoza ndi kwambiri osauka kuposa equipments ena audio.

Amuna ena ofunika amene anapanga mbiri

Ernst W. Siemens anali woyamba kufotokoza mphamvu kapena kusuntha koyilo transducer, ndi koyilo zozungulira wa waya m'munda maginito ndipo anathandiza kuti zosamukira axially. Iye akadandaule setifiketi wake ntchito US kwa Magneto magetsi zida chopezera mawotchi gulu la koyilo magetsi ndi mafunde magetsi kudzera anapatsidwa setifiketi No.149797 pa April 14, 1874.

Oliver Lodge ada mangala kwa setifiketi No.9712 British pa Apr. 27, chaka cha 1898, chifukwa bwino Makaniko ndi spacers nonmagnetic kusunga kusiyana mpweya pakati pa mizati mkati ndi kunja kwa ukuyenda koyilo transducer. Ichi chinali chaka chomwecho iye ntchito kwa setifiketi pa chochunira wake wotchuka wailesi.

Thomas Edison linaperekedwa ndi setifiketi British pa 1881, kuti kachitidwe ntchito mpweya wothinikizidwa ngati limagwirira amplifying kwa magalamafoni ake oyambirira yamphamvu, koma pamapeto pake kuthetsedwa chifukwa bwino zitsulo nyanga lotengeka ndi Kakhungu Ufumuyo cholembera ndi.

Harold Arnold padziko 1925 anayamba pulogalamu pa Bell Labs kusintha phonographic phokoso kujambula. Choyamba chinali mkuzamawu pakompyuta ntchito yatsopano zingalowe chubu, wachiwiri anali maikolofoni, ndipo chachitatu chinali Makaniko kuti kodi kusintha moyenera armature mayunitsi zithandize nkhani yaikulu.

Bell Laboratories mu 1931 anayamba njira ziwiri kudzera m'zokuzira mawu, wotchedwa anagawa osiyanasiyana kwa chionetsero ndi HA Frederick kulembamo vertically kudula. The mafurikwense okwezeka m'malo mwa nyanga yaing'ono ndi pafupipafupi zimene 3000 ndi okwana 13,000 Hz, ndi mafurikwense otsika ndi 12 inchi zazikulu phirilo mwachindunji Redieta wagawo ndi pafupipafupi ayankhe pasanathe 5db 50 10,000 Hz.

Mmene kudzera m'zokuzira mawu ntchito ntchito

The kudzera m'zokuzira mawu oyamba ntchito electromagnets chifukwa lalikulu, lamphamvu maginito okhazikika sanali kupezeka pa mtengo wololera.

The koyilo wa electromagnet ndi lake koyilo kumunda, anali imapatsidwa mphamvu ndi panopa kudzera awiri chachiwiri cha kugwirizana kwa dalaivala. Izi akutsirizika zambiri ankatumikira udindo wapawiri, akuchita komanso ngati kutsamwa koyilo imathandiza ya magetsi ya mkuzamawu amene Makaniko anali olumikizidwa.

AC ripple mu panopa anali attenuated ndi zochita za kudutsa koyilo kutsamwa. Komabe, AC mzere mafurikwense zinkangokhala modulate mbendera zomvetsera anatumizidwa ku koyilo mawu ndipo anawonjezera kuti phokoso lomveka kwa zoyendetsedwa mpaka chipangizo phokoso kubalana.

Khalidwe la machitidwe Makaniko mpaka 1950s anali ndi mfundo ano, osauka. Zochitika mosalekeza mu mpanda kapangidwe ndi zipangizo zomwe zachititsa kuti n'chinthu patsogolo lomveka. The patsogolo kwambiri yodziwika okamba masiku ano patsogolo zipangizo phirilo kumayambiriro zomatira apamwamba kutentha, bwino zipangizo okhazikika maginito, njira bwino muyeso, kompyuta kukanathandiza kapangidwe ndi amalire mchitidwe kusanthula.
