Isihlungi esingaphansi - indlela yokufeza umsindo omuhle kakhulu?

Abantu abaningi banesithakazelo kusihlungi esiphansi, okudingekayo ku-subwoofer. Ngokuvamile indlebe yomuntu ingaqonda umsindo, kusukela ngo-20 futhi iphela nge-Hertz ayizinkulungwane ezingu-20. Futhi amanothi, umsindo owenzeka emkhawulweni ophansi, yizona ezingezansi. Ngakho-ke, emkhawulweni ongaphezulu, umsindo ufana ne-squeak. Kulabo abafuna ukufunda ukuthi umsindo ozwakalayo kuma frequencies ahlukene, uhlelo oludalwa ngokukhethekile olungadingi ukufakwa okuhlukile ludalwa ngokukhethekile. Udinga ukulanda kuphela futhi unike amandla. I-interface yesimiso, futhi, ngeke idale ubunzima obukhethekile.

Lapho ufunda ukuthi yini isihlungi esiphansi, awufanele ukhohlwe ngemvamisa yokunqunywa, okwenyuka akudingekile. Uma wenza i-subwoofer, yenziwa ukuze imisindo engezansi ishiywe ingashintshi, kanti ama-frequencies aphezulu adluliselwa ngokuphazamiseka okukhulu. Ukuze wenze lokhu, sebenzisa isihlungi esikhethekile, esisusa umsindo ophezulu kakhulu.

I-subwoofer kufanele ihlangabezane nemigomo elandelayo: isikhulumi esincane esesikhulumi sidlala nayo, iphakamisa imvamisa yokuhlunga yezihlungi ezisetshenziswe ngaphansi. Ngamanye amazwi, uma isikhulumi sinesikhulumi se-bask 10 cm, imvamisa ye-cutoff kufanele ifinyelele ama-Hertz angamakhulu amathathu. Uma ubukhulu bekholomu ye-bass bulingana namasentimitha angamashumi amathathu, imvamisa ye-filter cutoff ifinyelela ku-Hertz eyikhulu.

Kodwa uma i-subwoofer inesikhulumi esincane, cishe cishe ngeke ikwazi ukukhiqiza ama frequencies aphansi kakhulu. Uma isimo sishintshwa, khona-ke intando yeningi iyakwazi ukuphinda ivuselele ama- frequencies aphansi. Okokuthi, i-subwoofer enhle ingathathwa ngokuthi ingaqalisa kanjani ama-frequencies aphansi. Izikhathi eziphakeme zivame ukukhiqizwa yi-subwoofer enokuphazamiseka okukhulu.

Ngokuvamile, imvamisa ye-cutoff ayibangeli izinkinga. Isele ukuxuba isihlungi esincane esiphambuka ngokwayo. Kungaba okungahleliwe noma okusebenzayo. Esikhathini sokuqala, lesi sihlungi siyisikhulu esikhulu esinama-capacitors amaningana. Kulesi simo, asikho isidingo sokufaka ama-amplifiers ahlukene. Futhi, akudingeki ukuthi ufake ukunikezwa kwamandla engeziwe. Isihlungi se-passive kufanele sixhunywe ngqo kumathinki we-subwoofer.

Enye into oyidingayo lapho ufunda lesi sihloko ukuhamba kwezomnotho, okuyinto ipharamitha ekhethekile ebonisa ukuthi umsindo uhlanganisiwe kangakanani ezingeni elingaphezu kwevriv. Ngokuvamile, uma ufaka izihlungi, ukunyamalala komsindo kumvamisa ophezulu kufanele kwenzeke ngokushelelayo, ngaphandle kwehla ngokuzumayo.

Ngenxa yokuthi isihlungi esincane esiphansi sisebenzisa imvamisa ephansi yokunqunywa, futhi i-oda layo liphakeme, isidingo sokuklama singasusiwe. Kulesi simo, kufanele usebenzise isihlungi esisebenzayo. Ukwehluleka kwawo kuyimfuneko ephoqelekile ekunikezeni amandla okuhlukile kanye ne-amplifier esiteshini se-subwoofer. Ngaphezu kwalokho, kwezinye izimo, ungadinga isitha.

Kule mikhawulo eyisisekelo, enesihlungi esiphansi, esiphelile.
