A gudzanzwi, mukurukuri, kana mutauri hurongwa chinhu electromechanical transducer kuti vatendeuki ane zvemagetsi chiratidzo. Izwi gudzanzwi rinogona kureva munhu mumwe mudziyo kana mutyairi, uye gadziriro yakakwana rine imwe yakakomberedzwa corporating mumwe kana kupfuura vatyairi uye yokuwedzera Electronics.
Nemasipika ndivo kupfuura shanduka zvinhu chero maCD ino, uye vane basa segwapa anzwike kusiyana pakati zvimwe kufanana inzwi enyika. Gudzanzwi waivako kana zvakarurama rinozvibereka chiratidzo pasina kuwedzera kusarurama zviri varombo kupfuura vamwe zvakarekodhwa equipments.
Vamwe varume zvinokosha uyo akaita nhoroondo
Ernst W. Siemens ndiye akatanga kurondedzera simba kana uchifamba coils transducer, ane raundi Coil of waya ari remagineti uye akatsigira kuitira kuti yaizotamira axially. Iye kudare US wake bvumidzwa chikumbiro kuti Magneto yemagetsi midziyo nokuda kuwana zvokuimba kufamba ane zvemagetsi Coil kubudikidza nemagetsi dzenzvimbo kuburikidza rakabvumirwa bvumidzwa No.149797 musi April 14, 1874.
Oliver Lodge kudare kuti British bvumidzwa No.9712 musi Kubvumbi 27, 1898, kuti nani gudzanzwi pamwe nonmagnetic spacers kuchengeta mhepo musiyano pakati yomukati uye dzokunze matanda inonakidza coils transducer. Izvi ndiye gore iye aishanda kuti bvumidzwa yake yakakurumbira redhiyo tuner.
Thomas Edison wakabudiswa munhu bvumidzwa British panguva 1881, nokuti hurongwa kushandisa compressed mhepo sechinhu amplifying nomazviri ake mangwanani humburumbira magiramufomu, asi iye pakupedzisira akagadzirisa nokuda yaizivikanwa simbi nyanga anosundwa Kamudzira dzakabatana chinyoreso.
Harold Arnold kumativi 1925 akatanga chirongwa pa Bell Labs kuvandudza phonographic inzwi yakarekodwa. The chokutanga chokutanga chaiva electronic gudzazwi kushandisa idzva Vacuum chubhu, wechipiri waiva maikorofoni, uye wechitatu waiva gudzanzwi kuti aizonatsiridza yakadzikama armature zviumbu akagadzirirwa yavose.
Bell Laboratories muna 1931 vakava mbiri nzira nemasipika, akadana yakakamurwa chikuva chiratidzo HA Frederick pamusoro vertically kuchekwa zvinyorwa. Matunhu frequencies vakanga chikatsiviwa nyanga duku ine kakawanda kwakaita 3000 kusvika 13.000 hz, uye shoma frequencies ne 12 padiki simba cône zvakananga redhiyeta chikwata ane kakawanda mhinduro mukati 5db kubva 50 kusvika 10,000 hz.
Sei nemasipika anoshandiswa kushanda
The nemasipika rokutanga vakashandisa electromagnets nekuti guru, simba zvachose magnets a havana kuwanikwa pa musoro mutengo.
The Coil ane electromagnet, yainzi munda coils, akanga avapa maererano kuitika kuburikidza wechipiri vachipiwa kwokubatana mutyairi. Izvi ichitenderera kazhinji Aishumira hunyambiri basa, kuita uyewo kachidza coils inonzwika apo simba nerubatsiro gudzazwi dzakasvikwa gudzanzwi raiwanzobatana.
AC ripple ari mudare rakanga attenuated kubudikidza Zvakaitwa nomunyika kachidza coils. Zvisinei, AC mutsetse frequencies nomuitiro modulate mashoko ekuteerera chiratidzo kutumwa inzwi coils uye akawedzera kuti anzwike nokuimba munhu dzinofambiswa kumusoro inzwi kubereka mudziyo.
Kunaka gudzanzwi enyika kusvikira 1950s akanga nezvinodiwa ano, murombo. Kuramba kuitika zvakapoteredza magadzirirwo uye zvinhu zvakatungamirira kuti chinokosha anzwike kuvandudzika. Zvikuru chinozikamwa kuvandudzwa vakurukuri ano kuvandudzwa cône zvokuvakisa, pakatanga rokumusoro tembiricha adhesives, nani zvechigarire magineti zvinhu, kwakavandudzwa nekuyera unyanzvi, kombiyuta Ichibatsirwa magadzirirwo finite maatomu akafanana kuongorora.
