nidaamka samaacad, Gudoomiyaha, ama Gudoomiye A waa transducer ah korontada in badasha signal koronto. samaacad Ereyga gudbin karaan qalab gaar ah ama darawalka, iyo nidaam dhamaystiran oo ka kooban xero ah corporating mid ama ka badan darawalada iyo korontada oo dheeraad ah.
Sameecadaha waa xubno badan variable in nidaamka wax maqal, oo ka masuul ah calaamad oo kala duwan la maqli karo u dhexeeya nidaamka codka haddii kale isku yihiin. waxqabadka samaacad ama saxnaanta tarmo signal oo aan ku daray dhalanrog waa weyn u miskiinsan yahay in qalab kale audio.
Qaar ka mid ah dadka oo muhiim ah, kuwaas oo dhigay taariikh
Ernst W. Siemens ahaa kii ugu horeeyay si ay u sharxaan transducer gariiradda firfircoon ama dhaqaaqin, la gariiradda wareeg ah ee xarigga duurka a magnetic iyo taageero si ay u dhaqaaqi karaan axially. Waxa uu gudbiyay codsigiisa patent ee Maraykanka u qaabilsan nabadgelyada Magneto a korontada si loo helo dhaqdhaqaaqa farsamo ee gariiradda koronto by hadda korontada la isugu gudbiyo dhex siiyey No.149797 patent on April 14, 1874tii.
Oliver Lodge fayl No.9712 patent British on Abri 27, 1898, waayo samaacad loogu kordhinayo spacers nonmagnetic in ay sii farqiga u dhexeeya hawada ulaha gudaha iyo kuwa dibadda u dhaqaaqo transducer gariiradda ah. Tani waxa ay ahayd sanadkii la mid ah uu dalbaday patent ah uu tuner radio caan ah.
Thomas Edison la soo saaray patent a British inta lagu jiro 1881, nidaam la isticmaalayo hawada tilmaantay Tifaftirayaasha sida hab jaha kale oo phonographs dhululubo hore, laakiin waxa uu ugu dambeyntii degeen for geeska birta yaqaan kexeeyey by xuub lifaaqan stylus ah.
Harold Arnold agagaarka 1925 barnaamijka bilaabay at Bell Shaybaarka si loo hagaajiyo duubo codka phonographic. mudnaanta kowaad wuxuu ahaa kordhiyo elektarooniga la isticmaalayo tuubo vacuum cusub, labaadna wuxuu ahaa makarafoonka, iyo kan saddexaad oo ahaa samaacad in uu horumarin doono unugyada armature dheeli tiran loogu talagalay cinwaanka dadweynaha.
Bell Laboratories ee 1931 horumariyo hab laba sameecadaha, loo yaqaan kala duwan oo ka kala qaybsameen, waayo, dibad by HA Frederick diiwaanka vertical gooyay. The mawjadaha sarsare bedelay gees yar oo jawaab inta jeer ee 3000 in 13,000 Hz, iyo mawjadaha hooseeyo by koorta firfircoon unit hiitarka si toos ah 12 inch ah jawaabta inta jeer gudahood 5db ka 50 ilaa 10,000 Hz.
Sidee sameecadaha loo isticmaalo in lagu shaqeeyo
The sameecadaha ugu horeysay isticmaali electromagnets maxaa yeelay waaweyn, magnet-joogta ah oo awood badan ma ay heli kharash macquul ah.
gariiradda of electromagnet ah, loo yaqaan gariiradda beer, waxaa usoo noolaatay by hadda iyada oo labo ka mid labaad oo xiriir darawalka. Tani waxay fuuli jiray sida caadiga ah waxay u adeegeen door dual, ayaa sidoo kale ku simaha sida gariiradda ceejiya ah dabaqii labaad korontada ee kordhiyo si ay taas oo uu samaacad la xiran ee.
Cabidkariin AC in hadda la dhimay by tallaabada ee marayay gariiradda ceejiya ah. Si kastaba ha ahaatee, mawjadaha line AC lagu waday inuu modulate signalka audio loo diray gariiradda codka iyo ku daray in ay Hum ku maqli karo qalab dhalmo codka shaqeeya kor.
tayada nidaamka samaacad ilaa 1950 waxa uu ahaa, by heerka casriga ah, dadka saboolka ah. horumar joogto ah ee design iyo qalabka xero ayaa keentay in ay horumar la taaban karo la maqli karo. Horumarka ugu weyn ee ku hadla casriga ah waa hagaajinta qalabka koorta, hordhaca ah ee adhesives heerkulka sare, fiicnaaday qalabka magnet joogto ah, farsamooyinka cabbirka hagaagay, design computer dhameeya iyo falanqaynta element uguna.
