Subwoofer a me ka horn nenoaia alapine (frequency) i nā pane

Mua i loko o ka seventies a me eighties o ka hope ke kenekulia, ka mea i manaoio aku i ka nui 'ōlelo i loko o ke kolamu, i ka maikaʻi. ʻO kēia kokoke i ka hoʻolālā o ka sonification o accomodations i kekahi mau mea okoa hoi o ka makana o Dolby hoopuni ae i'ōnaehana me kuokoa subwoofer i kekahi mau mea e hoonaueia'na na mea i hilinaʻi ai i loko o ka e pono ai ke olelo kani me ka mau 'ōlelo, akā, na kânaka ua haʻalele loa i ka hailona.

I ka ninau o ka mea e ia i keʻano o ka'ōlelo, mālama e pili ana i nā mea haku polokalamu a me nā technologists mai o ka manawa i ka wa a ka electromechanical transducers i hele mai i loko o ke ola. Aia He He kekahi ke ku e ana i loko o nā koi no ka diffuser. Ma ka kekahi lima, i mea e like ai ma lalo hōʻike hou, i ka nui uila huahelu mea e e nui lakou e maona ai a me ka nunuiʻume mākenēki'ōwili hao, ma o ka "e oniu nui uila" lau ka hapanui o ka mana. Ma ka kekahi lima, kiʻekiʻe nä alapine i kauoha mai i kā mākou he lauwili anei oscillatory'ōnaehana a me ka palena iki 'oni'.

Ultimately, ua hele mai nā mea haku polokalamu acoustic accessories i ka Logical pāʻoihana ma ke kolamu hoʻonoho pū hana woofers, a no laila,-kapaia "tweeter". Naʻe, i loko o keia hihia e kūpono ai ka "ole" ma ka waena o ka pae, akā, i kēia pilikia ua eliminated ma ka hou ana o ke kolu o ka horn hana ana ma keia laulā.

Frequency pane a pela ua kūponoʻia ma luna o ka holoʻokoʻa audible koa. Ke woofer hiki ke hoʻohana me nā kānana, akā, ma ka mea e emi i ka haawe ana ma luna o laila, a hooloihi mai i mea paʻa, ua hoolako ia me ka inductance puke-pili,ʻaʻole transmissive meakino a me ka ale kiʻekiʻe. Ka waena loudspeaker ua i hoomahaiaʻi mai ka i "waffle" i ka uila, a me ka luna neaiae eiiiiiaiou. No keia hopena, ma ka laina me ka mea komo i ka'ōwili hao, a me ka mea pihana. Like no me ka "tweeter", alaila, he hiki e lako wale manao no ka mea, mai ka poe mai o ka hola 3 kHz, a ma luna, no keia loudspeaker ma ka moʻo me keia capacitance ua hui pū.

Hoikehonua, nui uila loudspeaker mea he luna 'electromechanical hoʻoluku. I ka papa o ka diffuser mea he nui. E hoolako ia no ka lōʻihi manawa, e koi mau kumuhana e pale aku laholio deformation, a pela aua kona waiwai. Nō kāu, i ke kihi emitter ua pili me ka laholio ke komo lima diffuzoroderzhatelem semicircular pauku.

Mapuna o kekahi mau millimeters, e i ka maopopo ala, ai ole i ka maka o ka'ōwili hao e e "overwritten" kikowaena Mākēneki. Ua hoʻolako i ka centering Kauai ua ana i o ke kēpau mea hoʻopaʻa impregnated perforated lole me ka annular corrugation.

Woofer - he kiʻekiʻe-ʻenehana lima kūlana kiʻekiʻe i loko o kona kūkuluʻia e hoʻohana i nā nā E hana 'ia ma ka pīlali i? Iecaianoaaiiuo. Ke diffuser pono e uaua, alaila, o ka ikaika o ka'ōwili hao e e pū i hiki ma kona luna kokoke koke, a me ka oluolu i accelerating ano ma ka liʻiliʻi loa e hiki manawa lag. Naʻe, i loko o ka hapa nui o ka loa a me ka pipiʻi kiʻekiʻe-e like ai 'ōlelo, oddly lawa, hoʻowahāwahā i nā hana' ia he a pau o ka enehana kēia, pepa ua hoʻohana 'ia e like me ka'ōlelo mua, i i invented i loko o ka makahiki 1925 ma ka Americans nāʻai Rice, a Kellogg.

Ua lilo ke woofer i integral hapa o ka manao o kekahi kiʻekiʻe-e like ai horn nenoaiu.
