Mawu oyamba analembedwa mu 1877 ndi Thomas Edison pogwiritsa ntchito luso lake lotchedwa galamafoni, limene analandira patenti patatha chaka chimodzi. Izi zidajambula ndi kutulutsanso mawu ndi singano yachitsulo pamasilinda a sera. Phonograph yomaliza inapangidwa mu 1929. Zaka zisanu ndi zinayi pambuyo pake, Emil Berliner anapanga chopukutira chotembenuza chimene chinali chosiyana ndi galamafoni mwa kugwiritsira ntchito mbale zafulati zomwe poyamba zinkapangidwa ndi zinki, labala lolimba ndi magalasi, ndipo kenako ndi shellac. Lingaliro lachidziwitsochi linali kuthekera kojambula ma disks ambiri, zomwe zinapangitsa kuti makampani a galamafoni apite patsogolo kwa zaka zambiri.

The turntable woyamba

Mu 1948, panali kusintha kwina kwakukulu m'makampani ojambula nyimbo. Columbia Records (CBS) yapanga rekodi yoyamba ya vinyl yokhala ndi liwiro losewera la 33⅓ rpm. Vinilu komwe ma disc adayamba kupangidwa amalola kusewera kwabwinoko kwa mawu ojambulidwa. Tekinoloje yopangidwa idapangitsa kuti zitheke kujambula zidutswa zazitali mpaka mphindi zingapo. Pazonse, zomwe zili mu chimbale cha 12-inch zinali pafupifupi mphindi 30 za nyimbo kumbali zonse ziwiri. Mu 1949, chimphona china cha mbiri RCA Victor anapereka 7 inch single. CD iyi inali ndi kujambula kwa mphindi pafupifupi 3 mbali iliyonse ndipo inkasewera 45 rpm. Ma CD ameneŵa anali ndi bowo lalikulu pakati kotero kuti akanatha kugwiritsiridwa ntchito m’madisiki akulu akulu, otchedwa jukebox amene anali m’fasho m’zaka zimenezo m’malesitilanti amitundumitundu ndi makalabu ausiku. Pamene mawilo akusewerera awiri a 33⅓ ndi 45 discs adawonekera pamsika, mu 1951 chosinthira liwiro chinayikidwa mu ma turntable kuti chiwongolere liwiro lozungulira ku mtundu wa disc yomwe ikuseweredwa. Rekodi yokulirapo ya vinyl yomwe idaseweredwa pakusintha kwa 33⅓ pamphindi imodzi idatchedwa LP. Kumbali ina, chimbale chaching'ono chokhala ndi nyimbo zochepa, chomwe chimaseweredwa maulendo 45 pamphindi, chimatchedwa nyimbo imodzi kapena nyimbo.

Sitiriyo ya system

Mu 1958, chimphona china chojambula ku Columbia chinatulutsa nyimbo yoyamba ya stereo. Mpaka pano, ma Albamu a monophonic okha ndi omwe amadziwika, mwachitsanzo, omwe mawu onse adajambulidwa munjira imodzi. Makina a stereo adalekanitsa phokosolo kukhala njira ziwiri.

Makhalidwe a mawu opangidwanso

Zolemba za vinyl zili ndi ma grooves omwe ali ndi kusagwirizana. Ndi chifukwa cha zolakwika izi kuti singano imapangidwa kuti igwedezeke. Mawonekedwe a zolakwika izi ndiakuti kugwedezeka kwa cholembera kumapanganso siginecha yamayimbidwe yojambulidwa pa disc panthawi yojambulira. Mosiyana ndi maonekedwe, teknolojiyi ndi yolondola komanso yolondola. M'lifupi mwa poyambira woteroyo ndi ma micrometer 60 okha.

Kukonzekera kwa RIAA

Tikadafuna kujambula mawu okhala ndi mizere yofananira pa rekodi ya vinyl, tingakhale ndi zinthu zochepa pa disc chifukwa ma frequency otsika angatenge malo ambiri. Chifukwa chake, musanalembe zolemba za vinyl, kuyankha pafupipafupi kwa chizindikirocho kumasintha malinga ndi zomwe zimatchedwa kuwongolera kwa RIAA. Kuwongolera uku kumakhala kufooketsa otsika ndikuwonjezera ma frequency apamwamba musanayambe kudula zolemba za vinyl. Chifukwa cha izi, ma groove pa diski amatha kukhala ocheperako ndipo titha kupulumutsa zomveka zambiri pa diski yomwe wapatsidwa.

Preamplifier

Choyimira choyambirira chiyenera kugwiritsidwa ntchito kubweza ma frequency otsika omwe adatayika omwe adangojambula pogwiritsa ntchito kufanana kwa RIAA. Choncho, kuti timvetsere zolemba za vinyl, tiyenera kukhala ndi socket ya phono mu amplifier. Ngati amplifier yathu ilibe socket yotere, tiyenera kugula preamplifier yowonjezera ndi soketi yotere.

Kukambitsirana

Tekinoloje yeniyeni yomwe idapangidwa zaka makumi angapo zapitazo ndipo imagwiritsidwa ntchito ndi mamiliyoni a ma audiophiles okonda mawu a analogi mpaka lero angakhale odabwitsa. M'chigawo chino, tinayang'ana makamaka pa chitukuko cha vinyl record, mu gawo lotsatira tidzayang'ana kwambiri pazinthu zazikulu za turntable ndi chitukuko chake.
