He aha te subwoofer waka?
Ko te subwoofer o te motuka he wāhanga matua o te pūnaha oro motuka e tino kawenga ana mō te whakaputa i ngā oro auau-iti (mai i te 20Hz ki te 250Hz). Ko tana mahi matua he huri i ngā tohu hiko ki ngā ngaru oro auau-iti hei whakaatu i ngā pānga oro papatahi pērā i te patu pahu, te papatahi, me te haruru miihini, hei whakarei ake i te whakarārangi me te rumaki o ngā pānga oro puoro, kiriata rānei.Youdaoplaceholder0 Mō te hanganga me te kaupapa mahi, ko te kaikorero pāorooro waka he mea hanga i te nuinga o te wā mai i tētahi pūnaha hiko hikohiko (pēnei i ngā aukume, ngā koiri reo), he pūnaha wiri ā-ringa (pēnei i ngā diaphragms, ngā ngaru puna), me tētahi pūnaha tautoko anga. Ka whakaputahia he papa aukume mā te akiaki i te koiri reo mā roto i ngā huringa o te iahiko, ka akiaki i te diaphragm ki te wiri me te pana i te hau ki te whakaputa oro. He maha ngā wā ka whakamahia e ia ngā kōne pepa matotoru me ngā koiri reo kua whakapakaritia hei whakatutuki i te hiahia mō ngā kaha o te auau iti nui, hei tāpiri atu ki te tweeter (te kawenga mō te wāhanga auau teitei).
I roto i tētahi pūnaha oro motuka, ka pā te tūranga tāutanga o te subwoofer (pērā i te tatau motuka, i raro, i roto rānei i tētahi kāpata motuhake) ki te kaha me te māramatanga ā-wāhi o te oro papatahi. Nā te iti o te utu, he maha ngā wā ka whakamahia noa ngā kaikōrero whānui-katoa ki te pūnaha oro motuka taketake, ā, ka hua ake he oro papatahi angiangi. Mā te tāuta i tētahi subwoofer motuhake ka taea te whakapai ake i te wheako whakarongo. He maha ngā wā ka mahi tahi me tētahi oro whakawhiti, ka whakauruhia rānei ki roto i tētahi subwoofer hei whakarei ake i te pānga auau tino iti.
Ko te subwoofer i roto i te motuka he wāhanga o te pūnaha oro e tika ana kia whakaputa i ngā oro auau-iti (mai i te 20Hz ki te 200Hz). Ko tana mahi matua he whakarei ake i te urupare auau-iti, kia pai ake ai te paparanga me te rumaki i ngā pānga oro puoro me ngā kiriata.
Ka taea e te subwoofer te whakarei ake i te wheako whakarongo. Mā te whakaputa anō i ngā āhuatanga auau-iti pērā i te patu pahu me te pātere, ka kaha ake te manawataki, ka mīharo ake te āhuarangi. Ina koa i te wā e purei ana i ngā puoro hiko, i ngā kiriata mahi rānei, ka taea e ia te waihanga i te ahua rumaki me te pānga.
I roto i te taiao haruru, ka taea e te kaikorero reo pāoro te "huna" i te pokanoa auau-iti. Ko te haruru o te miihini me te haruru hau e puta mai ana i te motuka i te wā e whakahaerehia ana he iti iho i te 200Hz, ka taea te huna ngāwari i te wāhanga auau-iti o te puoro. Ka hipokina e te subwoofer ēnei haruru mā te whakanui ake i te pēhanga oro auau-iti, ā, ka whakahokia mai te taurite puoro.
Mai i te tirohanga hangarau, ka whakamahia e te subwoofer he diaphragm whānui me te pūnaha ara iahiko aukume kaha hei akiaki i te hau, hei whakarei ake i te taumata pēhanga oro me ngā āhuatanga whakawhiti. Mā te arotau i te hoahoa o te kāpata ka taea hoki te whakahōhonu ake i te toronga auau-iti, ka nui ake te kī o te pāoro.
He maha ngā āhuatanga ka pā mai ai te hē o te subwoofer o te motuka. Kei raro nei ngā whakaaro me ngā otinga mō te rapurongoā i runga i ngā āhuatanga noa. Me tīmata mā ngā āhuatanga māmā, kātahi ka ruku hohonu haere.
Ngā mahi rapurongoā mō Youdaoplaceholder0: Tuatahi, whakaūhia te whānuitanga o te hapa, tirohia mēnā kei te hē te pūnaha haona waka katoa, kei te hē rānei te wāhanga pāorooro anake. Kei roto i te tirotiro hononga ara iahiko Youdaoplaceholder0:
Tirohia mēnā kua pā te fiusi (hei tauira, kei roto i te pouaka fiusi maui o te kāpini o te taraiwa te fiusi HORN o te BYD F3, kua tohua ko "Horn", me te iahiko whakatauranga o te 15A). Mēnā kua pā, me whakakapi, ā, me tirotirohia te pūtake o te ara iahiko poto.
Tirohia mēnā kua wetekina, kua waikura rānei ngā poraka pito o te kaikorero, ā, kia mau tonu te mono.
Ka taea te tirotiro i te tinana o te kaikorero i runga i te Youdaoplaceholder0 mā ēnei huarahi e whai ake nei:
Inehia te ātete o ngā pito o te kaikorero mā te whakamahi i te mita maha. Ko te uara noa he 3 ki te 5 ohms. Mena ka whakaatuhia te mutunga kore (OL), tera pea kua wera te koiri o roto.
Pēhia, pupuritia te pātene pū mō te wā roa, ka whakarongo tata ki te pū kia kite ai mēnā he tangi "tap-tap" kei te rangona. Ki te mea kāore he tangi, he tohu tēnei kua pakaru te pū, ā, me whakakapi. Ki te kore he tangi, arotahi ki te tirotiro i te ara iahiko.
I te tirotiro i te rārangi me ngā āhuatanga o waho, kia mōhio koe:
Tirohia mēnā kua tawhito ngā waea, kua pakaru, kua ngoikore rānei te pa atu, inā koa te puna karaka (hairspring) i raro i te urungi, he mea ka whati pea nā te hurihuri pinepine.
Kaua e whakamahi i te pū wai ki te pū tika i te wā e horoi ana i te motuka kia kore ai te wai e mimiti ki roto, e waikura ai.
Ngā āhuatanga o te whakatūnga pūnaha oro me te tiaki ngaio o Youdaoplaceholder0:
Whakatikatikahia te whakaōrite oro kia kore ai te oro pārū e whakawetohia, e iti rawa rānei te oro.
Mena kei te whakapaetia he hapa kei te whakakaha hiko, kei te subwoofer rānei, me whai taputapu ngaio hei whakamātautau i te putanga hiko.
Mena ka mau tonu te raruraru i muri i te tirotiro whaiaro, me whakapā atu ki ngā kaimahi tiaki ngaio kia kore ai e pāngia e te mahi matapo.
