Machitidwe a Adilesi ya Anthu Onse (PA)amagwiritsidwa ntchito kwambiri m'mafakitale, m'masukulu, m'malo oyendera anthu, komanso m'nyumba zamalonda polengeza, nyimbo zakumbuyo, komanso polankhulana zadzidzidzi.

Popanga dongosolo la PA, limodzi mwa mafunso omwe amafunsidwa kawirikawiri ndi awa:

Kodi kusiyana pakati pa okamba amagetsi okhazikika ndi okamba otsika a impedance ndi kotani?

Mitundu yonse iwiri imagwiritsidwa ntchito kwambiri mu makina olankhulira, koma imagwira ntchito zosiyanasiyana kutengera kukula ndi zofunikira za kukhazikitsa.

Kodi Oyankhula Okhazikika a Voltage Ndi Chiyani?

Ma speaker amagetsi okhazikika amagwiritsidwa ntchito kwambirimakina akuluakulu olankhulira anthu onseMachitidwe amenewa nthawi zambiri amagwira ntchito pa70V kapena 100V, ndichifukwa chake nthawi zambiri amatchedwaMakina olankhulira a 70V/100V.

Mu dongosolo la magetsi osasinthasintha, amplifier imatulutsa chizindikiro chamagetsi okwera, ndipo sipika iliyonse imakhala ndichosinthira chomangidwa mkatiTransformer iyi imalola okhazikitsa kusankha milingo yosiyanasiyana yamagetsi monga:

Chifukwa cha kapangidwe kameneka, ma speaker angapo amatha kulumikizidwamofanana pamzere womwewo wa chingwe.

Ubwino wa Machitidwe Okhazikika a Voltage

Zosavuta kulumikiza ma speaker ambiri

Yoyenera kutumiza mawu patali

Kugawa mphamvu kosinthasintha

Kapangidwe ndi kuyika kosavuta kwa makina

Mapulogalamu Odziwika

Ma speaker amagetsi okhazikika amagwiritsidwa ntchito kwambiri mu:

mafakitale ndi malo opangira mafakitale

ma eyapoti ndi masiteshoni a sitima

masukulu ndi masukulu

malo ogulitsira zinthu

malo oimika magalimoto ndi malo akunja

Malo amenewa nthawi zambiri amafunaokamba nkhani ambiri komanso madera ambiri ofalitsa nkhani.

Kodi Oyankhula Otsika a Impedance Ndi Chiyani?

Okamba otsika a impedance amagwira ntchito pa4 ohms kapena 8 ohmsndipo lumikizani mwachindunji ku amplifier popanda transformer.

Machitidwe awa nthawi zambiri amagwiritsidwa ntchito m'malo omweUbwino wa mawu ndiye chinthu chofunika kwambiri.

Ubwino wa Machitidwe Otsika a Impedance

Ubwino wa mawu

Kulumikizana mwachindunji ndi amplifier

Kusamutsa mphamvu moyenera

Mapulogalamu Odziwika

Okamba otsika a impedance nthawi zambiri amagwiritsidwa ntchito mu:

makina omvetsera kunyumba

zipinda zamisonkhano

malo odyera ndi malo ogulitsira mowa

malo oimbira nyimbo amoyo

makina owonera zisudzo ndi ma audio pa siteji

Komabe, machitidwe awa nthawi zambiri amapangidwa kuti agwiritsidwe ntchitomalo ocheperako okhala ndi ma speaker ochepa.

Voltage Yokhazikika vs Kutsika Kwambiri: Kusiyana Kwakukulu

Ndi Dongosolo Liti la Wokamba Nkhani Lomwe Muyenera Kusankha?

Kusankha pakati pa ma speaker a voltage osasintha ndi otsika impedance kumadalira momwe amagwiritsidwira ntchito.

Makina amagetsi okhazikika ndi abwino kwambiri ngati:

malo oyikapo ndi akulu

okamba nkhani ambiri amafunika

mtunda wa chingwe ndi wautali

dongosololi limagwiritsidwa ntchito polengeza kapena nyimbo zakumbuyo

Machitidwe otsika a impedance amakhala bwino ngati:

Ubwino wa mawu ndiye chinthu chofunika kwambiri

okamba nkhani ochepa okha ndi omwe akufunika

malo oyikapo ndi ochepa

Mapeto

Ma speaker amagetsi okhazikika komanso otsika kwambiri ndizofunikira kwambiri pakupanga ma audio system.

Machitidwe amagetsi okhazikikaNdiwo njira yodziwika bwino yokhazikitsira ma adilesi akuluakulu a anthu onse chifukwa amathandizira ma speaker ambiri komanso mtunda wautali wa chingwe.

Machitidwe otsika a impedanceKumbali ina, ndi oyenera kwambiri makina ang'onoang'ono a mawu komwe kumafunika mawu apamwamba.

Kumvetsetsa kusiyana kumeneku kumathandiza mainjiniya ndi okhazikitsa kusankha njira yabwino kwambiri yogwiritsira ntchito mapulojekiti awo a PA system.
