Nkhaniyi ikudziwitsani chomwe chiri passive radiator

Passive radiator ndi makina amawu omwe amagwiritsa ntchito "passive radiator" nthawi zambiri amakhala ndi active speaker unit ndi passive unit (passive radiator). Passive unit nthawi zambiri imakhala yofanana ndi active speaker unit, koma ilibe voice coil kapena drive magnet.

Ma radiator osadziwa zambiri nthawi zambiri amaonedwa ndi ogwiritsa ntchito osadziwa bwino ngati zinthu zopangidwa ndi opanga ma audio omwe amadula ngodya. Amaoneka ngati bass unit wamba; Koma mkati mwake, kapangidwe kake ndi kosiyana kwambiri. Palibe ma lead omwe amamangiriridwa, ndipo palibe maginito oyendetsera kumbuyo. Opanga ena ndi ogulitsa amawafotokozanso ngati "bass yayikulu pa sipika" kapena "double bass." Koma kwenikweni, sapanga bass yolimba.

Nanga n’chifukwa chiyani timagwiritsa ntchito ma radiator osagwiritsa ntchito mphamvu? Kodi ndi chiyani? Kodi ubwino wake ndi wotani wokhala nawo pa sipika?

Tikhoza kuyerekeza chotenthetsera chosagwira ntchito ndi "kulemera" komwe kumawonjezeredwa ku "kasupe." Kasupe "ali ndi mphete za diaphragm m'mphepete mwa beseni la pepala ndi mpweya wotsekedwa m'bokosi." "Kulemera" kumapangidwa ndi beseni la pepala ndi chotenthetsera chosagwira ntchito. Chotenthetsera chosagwira ntchito ndi gawo lofunika kwambiri pakupanga chotenthetsera chosagwira ntchito, chomwe chimagwirizana mwachindunji ndi mphamvu yomaliza ya mawu.

Radiator yopanda phokoso imatha kupanga resonance mwa kusintha counterweight, mofanana ndi forogo yosinthira. Komabe, mosiyana ndi mafoloko osinthira, kugwedezeka kwa ma radiator opanda phokoso sikuwola mofulumira mkati mwa mtunda winawake kutali ndi ma frequency obwerezabwereza. Ma radiator opanda phokoso nthawi zambiri amawola pa liwiro la 18db pa octave iliyonse. Ngakhale kuti curve imawoneka yokwera, imaperekabe kamvekedwe kothandiza ka theka lachisanu ndi chitatu kwa sipika. Izi zimathandiza kuti ipangidwe kuti imveke mozama kwambiri kuposa momwe woofer ya sipika ingathe kufikire, popanda "kulekanitsa" kwakukulu pakati pa ma frequency a woofer ndi a radiator opanda phokoso, zomwe zimapangitsa kuti phokoso la mawu likhale losalala kuyambira pamwamba mpaka pansi.

Kawirikawiri, ma radiator osagwira ntchito amanjenjemera ngati ma levers: pamene beseni la pepala la woofer likutuluka, beseni lake la pepala likutuluka; Kapena pamene beseni la pepala la woofer likutuluka, beseni la pepala likutuluka. Koma sizili choncho. Beseni la basso ndi beseni la radiator losagwira ntchito zimatha kusuntha mkati kapena kunja nthawi imodzi (izi zimatchedwa "mu gawo"), kapena kuphatikiza mayendedwe otsutsana ("kunja kwa gawo "- chitsanzo choopsa kwambiri ndi" kunja kwa gawo madigiri 180", monga tafotokozera kale ndi lever). Mwachidziwitso, kuti mawu awiriwa agwirizane, ayenera kusuntha mu gawo lolimba. Komabe, chifukwa cha zofooka zakuthupi, nthawi zambiri pamakhala mayendedwe osiyana pang'ono m'makina otere a resonance.

Chimodzi mwa zabwino zazikulu za makina amawu okhala ndi ma radiator osagwira ntchito ndikuti amatha kusintha ntchito yopanga bass kuchokera ku kukula kochepa kwa woofer kupita ku kukula kwakukulu kwa radiator yosagwira ntchito (woofer imafuna mpweya wokwanira kukankhira pamalo "-3dB" kuti ipange phokoso lomwelo mu frequency range). Pakadali pano, radiator yosagwira ntchito imatha kuchita kugwedezeka kwa mzere (kuyenda kobwerezabwereza kwa beseni la pepala mkati ndi kunja). Ubwino wina wodziwikiratu ndikuti malo oyankha pafupipafupi otsika amafika otsika kwambiri. Kuphatikiza apo, kukula kochepa kwa bass unit kungagwiritsidwe ntchito popanga, kuti bass ndi mid-frequency response response zikhale zolondola kwambiri, komanso kulekanitsa bwino.
