Mawu aukadaulo nthawi zambiri amatanthauza mawu omwe amagwiritsidwa ntchito m'malo osangalalira akatswiri monga ma holo ovinira, zipinda za KTV, malo ochitira zisudzo, zipinda zamisonkhano ndi mabwalo amasewera. Okamba nkhani akatswiri ali ndi mphamvu zambiri, mphamvu ya mawu imakwera, mphamvu yabwino, komanso mphamvu yolandirira. Ndiye, kodi zida zolankhulira zaukadaulo ndi ziti?

Kapangidwe ka okamba nkhani akatswiri: zida zamawu aukadaulo zimakhala ndi chosakanizira chowunikira; chosakanizira chowongolera mphamvu; chosakanizira chonyamulika; chowonjezera mphamvu; maikolofoni yamphamvu; maikolofoni ya condenser; maikolofoni yopanda zingwe; cholankhulira; cholankhulira chowunikira; cholankhulira chowongolera mphamvu; subwoofer yotsika kwambiri; Equalizer; Reverberator; Effector; Delayer; Compressor; Limiter; Crossover; Noise Gate; CD Player; Recording Deck; Video Disc Player; Projector; Tuner; Song Player; Headphones, ndi zina zotero. Zipangizo zambiri zimapangidwa.

Pali mitundu yambiri ya ma loudspeaker: malinga ndi njira zawo zosinthira mphamvu, amatha kugawidwa m'magulu amagetsi, ma elekitiromagineti, ma piezoelectric, ma digito, ndi zina zotero; malinga ndi kapangidwe ka diaphragm, amatha kugawidwa m'magulu ang'onoang'ono, ma cones ophatikizika, nyanga zophatikizika, ndi zomwezo. Pali mitundu yambiri ya ma shafts; malinga ndi diaphragm, poyamba imatha kugawidwa m'magulu a cone, dome, flat type, lamba, ndi zina zotero.; malinga ndi ma replay frequency, imatha kugawidwa m'magulu a high frequency, intermediate frequency, low frequency ndi full band speakers; malinga ndi maginito circuit. Njirayi imatha kugawidwa m'magulu akunja a maginito, internal magnetic type, dual magnetic circuit type ndi shielded type; malinga ndi mtundu wa maginito circuit, imatha kugawidwa m'magulu a ferrite, neodymium boron magnets, ndi maginito a AlNiCo magnet speakers; malinga ndi deta ya diaphragm. Yogawidwa m'magulu a mapepala ndi osakhala a cone, ndi zina zotero.

Kabati imagwiritsidwa ntchito kuchotsa ma acoustic short circuit a speaker unit, kuchepetsa acoustic resonance yake, kukulitsa dongosolo lake la ma frequency response, ndikuchepetsa kusokonekera. Kapangidwe ka mawonekedwe a kabati ka speaker kamagawidwa m'mitundu ya shelufu ndi mtundu wa pansi, komanso mtundu woyima ndi mtundu wopingasa. Kapangidwe ka mkati mwa bokosilo kali ndi njira zosiyanasiyana monga closed, inverted, band-pass, empty paper cone, labyrinth, symmetrical drive, ndi mtundu wa horn. Omwe amagwiritsidwa ntchito kwambiri ndi closed, inverted ndi band-pass.

Crossover ili ndi kusiyana pakati pa mphamvu yogawa ma frequency ndi magetsi ogawa ma frequency. Ntchito zazikulu za zonsezi ndi kudula ma frequency band, amplitude-frequency characteristic ndi phase-frequency characteristic correction, impedance compensation ndi attenuation. Power divider, yomwe imadziwikanso kuti passive post divider, imagawa ma frequency pambuyo pa power amplifier. Imapangidwa makamaka ndi zinthu zosagwira ntchito monga ma inductors, resistors, capacitors ndi zinthu zina zosagwira ntchito kuti ipange fyuluta, ndikutumiza zizindikiro za audio za frequency band iliyonse ku ma speaker a frequency band yofanana kuti iberekenso. Makhalidwe ake ndi otsika mtengo, kapangidwe kosavuta, koyenera kwa okonda masewera, koma zovuta zake ndi kutayika kwakukulu kwa insertion, mphamvu yochepa, komanso makhalidwe osakhalitsa.

Kusiyana pakati pa mawu aukadaulo ndi mawu apakhomo: Fotokozani mwachidule kusiyana pakati pa mawu aukadaulo ndi mawu apakhomo: mawu aukadaulo nthawi zambiri amatanthauza malo osangalalira aukadaulo monga maholo ovina, zipinda za KTV, malo ochitira zisudzo, zipinda zamisonkhano, ndi mabwalo amasewera. Malo osiyanasiyana, zofunikira zosiyanasiyana zoyendera komanso zosasinthasintha, komanso zinthu zosiyanasiyana monga kukula kwa malowo, ali ndi mayankho a makina amawu m'malo osiyanasiyana. Mawu aukadaulo nthawi zambiri amakhala ndi mphamvu zambiri, kuthamanga kwa mawu osewerera kwambiri, mphamvu yabwino, komanso mphamvu yayikulu yolandirira. Poyerekeza ndi mawu apakhomo, mtundu wake wa mawu ndi wovuta ndipo mawonekedwe ake siabwino kwambiri. Komabe, magwiridwe antchito a ma speaker a ma monitor ndi ofanana ndi a mawu apakhomo, ndipo mawonekedwe awo nthawi zambiri amakhala okongola komanso okongola, kotero mtundu uwu wa ma speaker a ma monitor umagwiritsidwa ntchito nthawi zonse m'ma audio a Hi-Fi apakhomo.

Zipangizo zomvera kunyumba:

1. Gwero la mawu: Chiyambi cha kayendetsedwe ka mawu. Magwero ofala a mawu m'makina a mawu apakhomo ndi monga zojambulira makaseti, zosewerera ma CD, zosewerera ma LD, zosewerera ma VCD ndi zosewerera ma DVD.

2. Zipangizo Zowonjezera: Kuti mugwiritse ntchito ma speaker amphamvu kwambiri popanga mawu, kutulutsa kwa mawu kuchokera ku gwero la mawu nthawi zambiri kumafunika kukulitsa mphamvu. Zipangizo zowonjezera zomwe zimagwiritsidwa ntchito masiku ano ndi ma AV amplifiers, omwe nthawi zambiri amakhala ma transistor amplifiers, koma tsopano ena okonda ma tube expanders amakondanso ma tube expanders.

3. Zipangizo zojambulira mawu: Cholankhulira, chomwe magwiridwe ake adzakhudza mwachindunji mtundu wa mawu.

4. Mzere wolumikizira: kuphatikiza mzere wolumikizira kuchokera ku gwero la mawu kupita ku amplifier yamagetsi ndi mzere wolumikizira kuchokera ku amplifier yamagetsi kupita ku sipika.

Kusiyana kwa khalidwe la mawu:

Ubwino wa mawu a okamba ndi wofunika kwambiri. Ubwino wa mawu umatsimikizira mphamvu ya nyimbo pa thupi ndi malingaliro a anthu. Anthu akale ndi okongola kwambiri: kulamulira dziko ndi makhalidwe abwino ndipo nyimbo ndi kugwiritsa ntchito mawu abwino komanso nyimbo zabwino kuti amange makhalidwe a anthu ndikupangitsa thupi, malingaliro, ndi mzimu wa anthu kufika pa mgwirizano, thupi ndi maganizo a munthuyo zidzakhala bwino limodzi. Chifukwa chake, ubwino wa mawu ndi wofanana ndi thanzi la thupi.

Phokoso labwino limapatsa anthu chifundo. Kumva kumeneku ndi kukhudza kochokera pansi pa mtima, kuchokera ku mbali yeniyeni ya anthu. Kumamveka ngati chikondi cha mayi kwa ana ake, kunyowetsa zinthu. Chete, koma chilipo. Phokoso limodzi lokha limabweretsa kugwedezeka kwa mzimu.

Cholinga chachikulu cha makina olankhulira kunyumba ndikupeza njira yolankhulira yomwe imafuna kumvetsera, monga njira yolankhulira ya zisudzo kunyumba. Koma banja ndi losiyana ndi zisudzo, kotero limafuna mawu osiyanasiyana amitundu yosiyanasiyana ya mawu. Limafuna nyimbo za pop, nyimbo zakale, nyimbo zopepuka, ndi zina zotero kuti lithe kubwezeretsa bwino zida zosiyanasiyana za nyimbo, ndipo limafuna kumva kukhalapo ndi mawu omveka poonera makanema.
