Coaxial acoustics - kodi ndiko kusankha bwino?

Magalimoto atsopano nthawi zambiri amakhala ndi zinthu zosavuta kumva. Iwo samapereka zitsime zakuya, kapena ma frequencies oyera. Inde, poti mumvetsere nkhaniyi, mphamvuzi zidzakwaniritsa, koma mumakonda okonda nyimbo zomwezo zidzakhumudwitsa kwenikweni, chifukwa simungamve nyimbo zomveka bwino. Ndi nkhani yowonjezereka kuti mupeze njira yachibadwa yamagetsi. Pankhaniyi, muyenera kusankha chimodzi mwazigawo ziwiri: chigawo kapena coaxial acoustics.

Zina zimakhala zogwirizana ndi machitidwe a coaxial acoustic. Zonsezi-nyengo zamakono zimakhala ndi oyankhula angapo, omwe amachititsa kuti phokoso likhale lodziwika bwino. Mwa ma frequencies, mawu amalekanitsidwa ndi mafayilo apadera - crossover. Amadziŵa kuchuluka kwa chizindikiro ndi kuwapereka kwa wokamba nkhani. Nthawi zina, makamaka pogwiritsa ntchito ma stereo modabwitsa, ma crossovers amapangidwa muzosiyana, zomwe zimateteza kumveka kuchokera kusakaniza mwadala.

Kuti muwombere molondola, m'pofunikira kuti muyandikire bwino zosankhidwa za fyuluta. Chifukwa cha zowonongeka, coaxial acoustics imabweretsa mafupipafupi ochuluka kusiyana ndi mawotchi apansi. Kawirikawiri, zizindikiro zoterezi zimayikidwa pazithunzithunzi zapadera, zomwe zimamuthandiza kwambiri khalidwe lakumveka.

Mtundu wina wa masewera olimbitsa thupi, ofala kwambiri pakati pa okwera magalimoto-okonda nyimbo - ndi chigawo chogwiritsira ntchito. Mofanana ndi coaxial acoustics, yafala kwambiri. Mfundo ya chipangizo chake ndi yofanana ndi coaxial acoustics, koma pali kusiyana kochepa. Ngati mkulankhulira wapitawo, magulu onse a magulu atatu omwe ali pafupipafupi amakhala mu malo omwewo, ndiye kuti pulogalamuyi imakhala yosiyana kwambiri. Chifukwa chake, woyendetsa galimoto amapeza mphamvu zosiyana, zomwe zimayikidwa bwino pafupi. Pachifukwa ichi, chithunzi chabwino choimba chimapezeka, chomwe chidzakhutitsa ngakhale womvetsera womvetsera.

Pali nsonga zingapo zofunika zomwe mukufunikira posankha dongosolo lililonse la coaxial acoustics. Choyamba, chinthu chachikulu ndi kusankha osankhidwa ndi mawu awo, osati maonekedwe awo. Zoonadi, mapangidwe a okamba ayenera kukhala oyenerera kumapangidwe ka galimoto, koma si ofunikira ngati mawu oyenera. Chachiwiri, kumbukirani kuti okhulupilira a oyankhulawo ndi mbali yaikulu yogwira ntchito. Mlingo wa kupatukana kwa mawu kumadalira pa chiwerengero cha zinthu za fyuluta, chifukwa momwe zimakhalire, zimakhala bwino. Chachitatu, mosasamala kanthu za mtundu wa wolankhula (chigawo kapena coaxial acoustics), ndi zofunika kuzigwiritsa ntchito ndi amplifier kunja. Pankhaniyi, phokoso lidzakhala bwino. Ngati wokamba nkhani akugwirizanitsidwa ndi stereo ya galimoto kapena mutu wina, samverani kukhudzidwa kwa wokamba nkhaniyo, chifukwa idzatanthauzira kumveka kwa mawu ake. Kulimbikitsidwa kovomerezeka kumachokera ku 92 decibels.
