Kungani udinga isihlungi subwoofer?

Abaningi abalandeli ufuna abe siqu ekhaya yaseshashalazini, kodwa hhayi wonke umuntu angakwazi ukukhokhela emzweni odlulayo ezinjalo. Wonke umuntu uphuma esimweni esinjalo ngendlela yakhe: umuntu uzothola izikhulumi elula Chinese, umuntu afanelekele imibhobho bass Soviet ezenziwe, kahle, eziphambili kakhulu, ukuba ulwazi ubunjiniyela kagesi, ngeke ukuklama subwoofer ongaphakeme imvamisa isiteshi ngokuzimela. Ikakhulukazi kusukela kulula ngempela.

Uhlolojikelele

Cabanga ngalokho kuyinto subwoofer ezivamile. Eqinisweni, isihlungi elula asebenzayo imvamisa ongaphakeme amasignali sokufaka ayanikezelwa kusukela okukhipha umugqa (kwesokunxele neziteshi kwesokudla), amplifier futhi woofer. Kulesi sihloko sizoxoxa element enzima kakhulu kudivayisi - isikimu elikuvumela ukuba self-babuthane ongaphakeme-pass isihlungi subwoofer. Amadivayisi anjalo nokuzala imvamisa esingeqile 40 Hz. Zisetshenziswa ngokuhlanganyela izipikha satellite ezincane. Subwoofers kukhona yekwentiwa. Lesi sakamuva ziphansi-imvamisa ikhanda, uxhumeke amplifier ezivamile. Lolu hlobo amadivayisi ayizwakali futhi engathandwa. Kuyinto into - ukhetho lokuqala. Ngo zinsizakuphila electronic esasihlukanisa asebenzayo ongaphakeme-pass isihlungi subwoofer futhi ehlukile amandla amplifier ahlukaniswa isignali bass okuyinto yanikezwa imibhobho main ngqo endaweni okuphakelayo ipheshana lapho zokuhlunga lokhu uyokwaziswa ngophawu leliphansi kakhulu ukuhlanekezela harmonic, njengoba kuqhathaniswa zokuhlunga okukhipha amandla amplifier. Ukwengeza amplifier ahlukene esiteshini subwoofer ngeke ukwandisa uhla ashukumisayo, kanye ukukhulula naphakathi amplifier kanye amaza okusezingeni eliphezulu by umthwalo ezengeziwe.

Hlunga ngokuba subwoofer: isikimu

Umfundi umenyiwe ukubukeza ezintathu izikimu samuntu leli thuluzi. Esikhathini uhlelo lokuqala, isihlungi elula olunikezwe subwoofer amisiwe njengenye nebululu Transistor. Serious izinga umsindo ngeke kwafezwa leli thuluzi, kodwa, ngenxa alula, kuyinto ephelele Wabasaqalayo hams. Kodwa isihlungi subwoofer evezwa embodiments ezimbili ezilandelayo, kwaba nemiphumela emihle kakhulu umise ngokwaso njengoba idivayisi ezinezici kakhulu. ama-apharathasi okunjalo isethwe ngokushesha ngemva emgqeni okukhipha amandla okokufaka amandla amplifier. Hlunga ngokuba subwoofer It libhekene umsindo ongaphakeme, ukhwaliti amandla ukusetshenziswa, kanye anhlobonhlobo supply voltage.

isiphetho

Efingqa, ake sithi ukuthi ukwengeza subwoofer ohlobo asebenzayo iyehlisa umngcele engezansi impendulo imvamisa kuthuthukisa ukucaciseleka womsindo Midrange futhi inikeza impela okusezingeni eliphezulu ivolumu ezingeni ngaphandle ukuhlanekezela. Ukususwa bohlu eyinhloko a yakhiqizwa isignali Okokufaka iziphuphutheki, kuvumela imvamisa ongaphakeme uzwakale ukhula sobala. Lokhu kungenxa yokuthi i-ongaphakeme imvamisa Isigaxa ikhanda akusho ngayo iyashintshashintsha nge amplitude okusezingeni eliphezulu, bazame kukhicita bass umsindo, kanjalo ethula ukuhlanekezela ku isiginali.
