Subwoofer Passive izipika yesimanje

Uyini subwoofer? Ngokuyisisekelo, uhlelo yokwenziwa - iyona ikholomu okuyinto ixhunywe kwikhompyutha noma emshinini okhulisa izwi. Kuyinto siyakwazi nokuzala ongaphakeme-imvamisa imisindo (ezinhlanu kuya Hz ezingamakhulu amabili). Kukhona subwoofers yekwentiwa kanye asebenzayo. Lokhu kuthinta ikhono lazo ukudlulisa umsindo.

Ukuze ezinhle uhlelo umsindo audio, ikholomu ezinkulu eyodwa kuphela, okuyinto ukuze kube lula zingafakwa ngaphansi kwetafula. Ukukhetha indawo efaneleka kakhulu yokwenza subwoofer, ungenza ngomzamo sinqande ukuma ngamagagasi ongaphakeme-imvamisa, okuyinto avele ekamelweni elincane afakiwe. Ngokuvamile esetshenziswa yokwenziwa subwoofer izipikha ekhaya yaseshashalazini ukubukela amabhayisikobho kanye imiphumela ekhethekile nomculo. Yena kahle lidlulisela imisindo ephansi.

Kwenzeka ukuthi izinhlelo subwoofer kungukuthi ohlanganiswe zokusebenza ezixhunywe kubo ngenxa ukungafani isigaba kanye amplitude-imvamisa yabo izici. Ukuze anqobe lezi zamehlo umsindo, abanye subwoofers nethuba kushintshwe isigaba futhi imvamisa eliphezulu.

izinhlobo subwoofers

Zimbili izinhlobo subwoofers: yekwentiwa. Kukhona imibuzo mayelana umehluko phakathi i subwoofer asebenzayo kusuka yokwenziwa lapho benza imisebenzi zezikhulumi?

Kuvele subwoofer asebenzayo uklame ke msindo amandla. Lapho-ke uyakwazi asuswe ongaphakeme-imvamisa amplifier umthwalo. Ngaphezu kwalokho, i-subwoofer asebenzayo ine asebenzayo crossover isihlungi ngokuvumela amaza okusezingeni eliphezulu, kuyasiza ukuze uxhumanise umsebenzi nge acoustic subwoofer broadband uhlelo. Kaningi anakho ongakhetha kulungiselelwa ezengeziwe ngokuhambisana nemibandela ukusetshenziswa. It has a control ithoni nevolumu.

Ngokungafani uhlelo asebenzayo yokwenziwa ayinakho amplifier. Kuyinto kuncike kudivayisi ukuthi ixhunyiwe: esikhulumini ikhompyutha. Ngakho-ke, it is kuhlanganiswe eyisisekelo stereo izikhulumi ibhekwa njengoba. Kungaba ixhunywe futhi ehlukile amandla amplifier. Ububi eyinhloko subwoofer yokwenziwa ukuthi kudala umthwalo ezengeziwe ku-stereo, yingakho ivolumu sinciphile Dynamics umsindo audio. Nokho, ayanda nozwela subwoofer, umthwalo encane amplifier.

Design izici, okuyinto uhlelo yokwenziwa, ukukufuna ngenkani ukuba afune izinto ngenkani kwabanye ngoba ukubekwa egumbini. It kumele idluliswe, uze uthole bass umsindo okuhle. Imvamisa ububanzi, okuyinto izici subwoofer, zingahlukaniswa zibe izinhlobo ezintathu: ezijulile (kusukela kwabaneminyaka engamashumi amabili kuya amane Hz), eliphakathi (kusuka amane amashumi ayisishiyagalombili Hz) kanye okusezingeni eliphezulu (kusuka ayisishiyagalombili komunye namashumi ayisithupha Hz) bass. I subwoofer umsindo okuhambisa kuncike endaweni diffuser. Kule amandla kanye bass organic ke kuncike.

umklamo subwoofers

Kudivayisi subwoofers yokwenziwa ababonakali ngezikhundla: uphondo, ukukhiphela futhi bandpass. Sinenkosi amathuba abo kanye nobubi obuthile. Woofer uphondo subwoofer usodongeni kusukela ebhokisini uphawu. subwoofers Kuvalelwe zilwane angase abe ezinkulu, usayizi besiyoba sikhulu, naphezu kweqiniso lokuthi banayo khono nokuzala ocebile, bass ezijulile.

Ukukhiphela abe isikhulumi esemgwaqweni izindlu. Ngokuvamile ngakolunye uhlangothi kukhona umgodi. Subwoofers onobuhle ezifana adlulisa bass amathoni ngaphansana Dynamics avaliwe, ngoba Yiqiniso ukwanda diffuser. Ziyakwazi ekahle amakamelo ezinkulu, njengoba ebonakala ngu ivolumu ephezulu.

buka Ngokulandelayo, okungenzeka uhlelo yokwenziwa - bandpass. Kuyinto isihlungi bandpass, sihlanganise izindawo izinhlobo ezimbili kuchaziwe ngenhla. Lokhu kubonakala eqinisweni lokuthi subwoofer inezingxenye ezimbili: ibhokisi avaliwe futhi reflex. Ngakho-ke, kukhona ingcindezi umsindo, kodwa ibhendi yokuvama iba ezincane.

Ukuze isetshenziswe ekhaya subwoofers ekahle elibiyelwe noma ukukhiphela. Ukukhetha kwabo, kufanele sinake okulandelayo. Subwoofer amplifier kumele singeqi izikhathi nengxenye amandla, okuyinto inohlelo isikhulumi. Le mfuneko kuzoqinisekisa izinga umsindo.
