Kodi a foni yamakono ntchito?

Pamene palibe chizindikiro chotumizira ndi kulandira chizindikiro, dera loyankhulirana lopanda manja liyenera kugwira ntchito polandira chizindikiro. Panthawiyi, kuchepetsedwa kwa transmit attenuator LS mu dera ndi kwakukulu kwambiri, pamene kutsekemera kwa attenuator LR ndi kochepa kwambiri, kotero kuti njira yolandirira imatsegulidwa kuti ikulitse. Mu AS, kutulutsa kwa chithunzi chojambulidwa cham'manja chopanda phokoso cham'manja cha amplifier chimagawidwa motere: chizindikiro chimodzi chimatumizidwa kwa wofananira B, ndipo chinacho chimatumizidwa ku transmission attenuator LS. Poyerekeza B, matalikidwe a siginecha yolowera amafananizidwa ndi matalikidwe a chizindikiro cholandilidwa. Poyerekeza mphamvu ya siginecha yopatsirana, wofananizira amatulutsa mulingo wapamwamba (kapena wotsika), potero akuyatsa cholumikizira. Chotsani cholumikizira cholandirira. Mwanjira iyi, kuchepetsedwa kwa cholumikizira cholumikizira ndikochepa kwambiri kuti kuwonetsetsa kusalala kwa njira yotumizira ma siginecha, kotero kuti dera loyimba foni lopanda manja lilowe m'malo otumizira mafoni, ndipo chizindikiro chotumizira chimatumizidwa ku gawo la transmit amplifier AS2 kudzera. ndi LS. Pambuyo pakukulitsidwa ndi AS2, chizindikirocho chimatumizidwa ku mzere wakunja kuti mulumikizane ndi foni ya gulu lina.

Chidziwitso chapano cha mawu chomwe chimatumizidwa ndi foni ya chipani china chimatumizidwa kwa wolandila LR kudzera pamzere wakunja, kenako ndikutumizidwa kwa amplifier yolandila mphamvu kudzera mu LR kuti ikulitsidwe, ndipo chizindikirocho chimatumizidwa kwa wofananira B kuti afananize ndi kutumiza chizindikiro. , wofananitsayo adzatulutsa mlingo wochepa (kapena wapamwamba), kotero kuti kuchepetsedwa kwa attenuator olandira LR omwe amawongolera njira yolandirira kumachepetsedwa kwambiri, ndipo kuchepetsedwa kwa kusintha kosinthika kwa njira yotumizira kumawonjezeka. Panthawiyi, dera loyimba lopanda mawu lopanda mawu lili m'malo olandila.

Panthawi yoyimba m'manja, mtunda pakati pa woyimba ndi foni umakulitsidwa kwambiri. Chifukwa cha kutalika kwa njira ya mpweya, zovuta za kubwezeredwa kowonjezereka komanso kuchepetsedwa kwa chiŵerengero cha ma signal-to-phokoso zimachitika. Malinga ndi mfundo yamayimbidwe a chipindacho, gawo la mawu a wogwiritsa ntchito limatumizidwa mwachindunji kwa wolandila, ndipo gawo lina limatumizidwa ku maikolofoni pambuyo powonetsedwa ndi chilengedwe. Popeza kuti kumva kwa anthu kumachedwa, zotsatira za mafunde omveka bwino zimakhala ndi zotsatira zochepa. Zina mwazomveka zobwerezabwereza zomwe zimatumizidwa mwachisawawa pambuyo powonetsera kangapo kuchokera ku makoma, ma desktops, pansi, ndi madenga sangaletsedwe, zomwe zimakhudza kumveka kwa kuyimba, zomwe zimachititsa zomwe zimatchedwa kuti hollow effect. Kukhalapo kwa reverberation, kumbali imodzi, kumachepetsa kusiyana kwa msinkhu pakati pa kumveka kwachindunji kwa mawu otumizidwa ndi phokoso lobwerezabwereza lomwe limabwera chifukwa cha kubwereza m'chipindamo, ndikuwonjezera kumverera kwa reverberation; kumbali ina, imachepetsanso kusiyana kwa msinkhu pakati pa chinenero chamkati ndi phokoso. , zomwe zimachepetsa chiŵerengero cha chizindikiro ndi phokoso la chizindikiro.
