He aha te mea te auau tarai-atu o te Wuwhaiti me pehea ki te whirihora tika

Whirihoranga hou te faananea- raa tangi taputapu, te hanga tangi karapoti kōrero takere wehenga mahi. he pūnaha ororongo taua ngā kaikōrero mua, a muri, he hongere pokapū me te Wuwhaiti.

kaimahi te whakamutunga ki te waihanga pānga tangi atu i te auau ngā raro i te 20 ki te 180 Herz. Fele whakamahia tenei kōwhiringa te ka matakitaki ana ngā hōtaka ataata me kiriata e roto i scenes o pahūtanga, rōnihi o ngā tākirirangi wāhi me ngā āhuatanga ōrite i roto i nei e hiahia ana koe ki te kaute puhoi nui ki te ruru i te rangi.

Tikanga, subwoofers hangaia mo te parau tumu kaha, e ko, i to ratou ake tīwerawera, te mana supply hanga-i roto i, me te whakarerekētanga. Mana me ngā tautuhinga ngā rua matua kakau "taumata» (Taumata) me te "auau cutoff» (Crossover Auautanga). He mārama te taumata Taumahi kakau, tenei ture kaha tangi. Na e te aha te rua o nga whirihoranga, he reira mārama e kore e te katoa.

Rerekē te aunui kaikōrero, Wuwhaiti iti e te tapa o runga o te whānuitanga auau. I roto i te tahuri, kua wehea basses ki hohonu - 40 Hz, reo - ki runga ki te 80 Hz, me te tiketike - ki runga ki te 160 Hz. O nei te whakaturia te auau cutoff, te hohonu tae e te pānga oro tei. I roto i ētahi wā, te whai wāhitanga i roto i te whānuitanga nui o te panguru hanga he haruru ngawari, hei tauira, ka whakarongo ki te waiata kiriata e matakitaki ana, kahore pānga motuhake ranei kua tāpiri. Ki te, Heoi, titau te pānga atu pākaha i runga i te pūnaha io o te pūtirotiro, hei tauira, i roto i te puka o te hu'ahu'a ra whare, me te makape aorangi, e taea te neke i te Wuwhaiti auau tarai-atu ofi ki infradiapazonu.

Tū, te rohe auau runga - mahi ohie. O te akoranga ahupūngao e mohiotia ai e te kaha o te tātari i te taonga ki te whakapai kanohi ki iarere iti me te hiko - ki tiketike. Ko te kupu, Ka taea e te LC-tātari ohie tōtika tutakina te whānuitanga rohe e hiahiatia ana, i te whakaiti i te taumata o te hihinga tohu koretake te. Ki "te pupuri i roto i" tāuru auau tiketike, me te reo ki te Wuwhaiti, he reira rawaka ki te taea terminals tāuru whakarara o te pūnga iti - he torutoru PF. Engari ka whakaiti i te taua tātari tahito whakautu auau maeneene rawa, na i roto i te mahi uaua atu ratou hoahoa.

Ano, whakaratohia te auau cutoff te me te tātari o te tohu putanga haere ki te whākaha reo kaha. Ki te mahi i tenei i roto i te tinana e tata ana te korero, ko tetahi poari ki ngā pūnga me inductors.

Ko te auau cutoff o te LPF (tātari haere iti) tano kia whakaritea, ahakoa i roto i ngā pūnaha iti-utu kore ai e taua mahi.
