Subwoofer ndi dongosolo wokamba pafupipafupi ayankhe

Poyamba makumi asanu ndi awiri ndi Mipingo ya atumwi otsiriza, ankakhulupirira kuti okamba yaikulu mu ndime ya bwino. Njira zamakono kuti gulu la sonification wa accomodations yosiyana kufalitsa dongosolo Dolby Azungulira ndi osiyana subwoofer penapake kugwedezeka kudalira phokoso mulingo woyenera wokamba ndi okamba angapo, koma mafani achoka ndithu kwambiri.

Funso la tiyenera mphamvu ya woyankhula, amasamala kutukula ndi technologists kuyambira pamene transducers electromechanical anabwera ku moyo. Pali kutsutsana zina zofunika kuti diffuser lapansi. Pa dzanja limodzi, kwa m'munsi kubwezeretsa quality, yoimba osiyanasiyana zikhale opondapo ndi chachikulu koyilo maginito, pa "anatenga yoimba" masamba ambiri a mphamvu. Komano, mafurikwense mkulu amafuna pazipita dongosolo lightness oscillatory ndi inertia osachepera.

Potsilizira pake, kutukula lamayimbidwe Chalk afika yankho lomveka mu ndime pabwino limodzi ntchito woofers ndi otchedwa "tweeter". Komabe, mu nkhani iyi izi umatanthauza "Kulephera" pakati pa sipekitiramu, koma vutoli likuchotsedwa ndi Kuwonjezera wokamba wachitatu ntchito osiyanasiyana izi.

Pafupipafupi ayankhe Choncho limagwirizana pa lonse lomveka gulu. The woofer akhoza opareshoni popanda Zosefera zina, koma kuti kuchepetsa katundu ndi kutalikitsa kwake, amaperekedwa ndi mndandanda-olumikizidwa inductance, osati transmissive sing'anga ndi mafunde. The Makaniko pakati amadziwikanso adathandizapo kukhala ndi "waffle" kuti yoimba, ndi zigawo chapamwamba chizindikiro. Kuti zimenezi zitheke, mu mzere ndi amaphatikiza ndi koyilo ndi capacitor. Koma "tweeter", ndiye pangakhale kuti aperekedwe anafuna okha izo kwa gulu pafupifupi 3 kHz ndi Kumwamba, Makaniko ili pa mndandanda ndi capacitance zikuphatikizidwa.

Modern yoimba Makaniko ndi zovuta electromechanical chipangizo. Njira ya diffuser ndi lalikulu. Kupereka izo kwa nthawi yaitali, zipangizo ayenera kulimbana mapindikidwe zotanuka chotero kusunga katundu wake. Childs, m'mphepete emitter chikugwirizana ndi mphira mphete diffuzoroderzhatelem gawo semicircular.

Chilonda cha millimeters ochepa, ayenera m'njira bwino, mwinamwake m'mphepete mwa koyilo adzakhala "overwritten" chapakati maginito. Iye anapatsa makina ochapira wokhudzana Nthawi zambiri munthu binder utomoni impregnated nsalu perforated ndi corrugation annular.

Woofer - chipangizo zina zamakono yomanga ake ntchito kutukuka onse posachedwapa kupanga polima. The diffuser ayenera kukhala yamphamvu, ndiye mphamvu ya koyilo adzakhala opatsirana kudutsa pamwamba pake nthawi yomweyo, ndiponso zosavuta mofulumira makhalidwe m'chaching'ono zotheka nthawi kwanthawi. Komabe, ambiri okamba mtengo kwambiri ndi apamwamba, oddly mokwanira, ngakhale patsogolo onse zamakono pepala ntchito monga nkhani yoyamba yomwe kupangidwa mu 1925 ndi Achimereka mphambu Rice ndi Kellogg.

The woofer wakhala mbali ya kamangidwe ka aliyense apamwamba wokamba dongosolo.
