He pūnaha whākaha reo, korero, korero ranei ko te transducer electromechanical e tahuri te tohu hiko. Ka taea e te whākaha reo wā kōrero ki te pūrere takitahi ranei atekōkiri, me te pūnaha oti arā, o te marae corporating tetahi atu ranei ngā atekōkiri me te hikohiko atu.
Tukuoro Ko nga mea timatanga tino tāupe i roto i tetahi pūnaha oro, me he kawenga mō tohua ngā rerekētanga tari'a i waenganui i ngā pūnaha tangi te kore ōrite. Whākaha mahi tika ranei i roto i te tārua i te tohu, kahore tāpiri distortion he tino iti ake i taua o te tahi atu meafaigaluega ororongo.
Etahi tangata nui nei i hanga hītori
ko Ernst W. Siemens te tuatahi ki te whakaahua i te transducer pōkai hihiri neke ranei, ki te pōkai porohita o te waea i roto i te papa autō, me te tautoko kia taea neke te reira axially. rēhitatia e ia tona US tono ārai mō te taputapu hiko Magneto mō te whiwhi i te kaupapa pūkaha o te pōkai hiko e ngā hiko tuku i roto i reira i homai ārai No.149797 i runga i April 14, 1874.
rēhitatia Oliver Lodge mō te ārai No.9712 Ingarangi i runga i eperera 27, 1898, mo te whākaha reo ake ki spacers nonmagnetic ki te pupuri i te āputa rangi i waenganui i nga amo roto, ki waho o te transducer pōkai neke. ko te taua tau tono ia mo te ārai i runga i tona PW irirangi rongonui tenei.
i puta Thomas Edison te ārai Ingarangi i roto i 1881, mo te pūnaha whakamahi i te hau kōpeke hei tikanga te faananea- raa mo ona kalamafoni rango wawe, engari ia noho mutunga mo te haona whakarewa maheni aia e te membrane piri ki te stylus.
Harold Arnold a tawhio noa 1925 timata hōtaka i Bell Labs ki te whakapai ake i tuhi tangi phonographic. Ko te kaupapa matua tuatahi te tīwerawera hiko mā te whakamahi i te ngongo mārua hou, tuarua ko te hopuoro, a ko te whākaha reo e e whakapai ake i te wae armature tautika whakawhanakehia hoki wāhitau tūmatanui tuatoru.
whakawhanakehia Bell Laboratories i 1931 te ara tukuoro e rua, ka karanga ngā wehea mo te whakaaturanga e HA Frederick o pūkete poutū tapahia. i whakakapi e te haona iti ki te whakautu auau o 3000 ki te 13,000 Hz, me nga iarere iti e te tihi hihiri kōwae whakamahana tika 12 inihi ki te whakautu auau roto 5db i 50 ki te 10,000 Hz te iarere teitei.
Kia pehea te nga tukuoro whakamahia ki te mahi
whakamahia i ngā tukuoro tuatahi electromagnets kore no te mea i wātea nui, aukume tūturu kaha i utu whaitake.
Ua faaitoitohia te pōkai o te hiko, ka karanga te pōkai mara, i nāianei i roto i te rua tuarua o hononga ki te kaiarataki. Tenei awhiowhio te te tikanga i mahi he tūranga rua, mahi hoki rite te pōkai kowaowaotia tātari i te supply te mana o te tīwerawera ki i hono te whākaha reo i.
AC pōkare i roto i te nāianei i attenuated e te mahi o haere i roto i te pōkai kowaowaotia. Heoi, i tiaki iarere raina AC ki te modulate te tonoa te tohu oro ki te pōkai reo, ka tāpiri ki te hum paraparau o te pūrere tangi reproduction powered ake.
Ko te kounga o ngā pūnaha whākaha reo tae noa ki te 1950 ko, na paerewa hou, rawakore. whanaketanga tonu i roto i te hoahoa marae me ngā rauemi kua arahina ki nga whakapainga e faaroohia nui. Ko te whakapai ake tino nui i roto i kaikōrero hou he whakapai ake i roto i ngā rauemi tihi, te whakataki o teitei adhesives pāmahana, pai ake rauemi aukume tūturu, pai ake tikanga ine, rorohiko whakakaha hoahoa me te tātari huānga fakataimí.
