Crossover nokuti vakurukuri - chii uye nei

Kana nekuisa ano redhiyo wemuTesitamende muridzi motokari ine kunonga zvakarurama Crossover. Chisarudzo ichi iri nyore kana uchiziva uye kunzwisisa chii uye chii chiri chinangwa, uye sezvo chikamu kwegadziriro mudziyo ino kushanda. Saka, ngationei kuti Crossover nokuda nevakurukuri.

Unhu, chinangwa

Crossover - iri rinokosha midziyo vaipa mutauri hurongwa, chikuru kushanda riri kubudisa aida kakawanda wokuriputira mutauri nerimwe. Sezvo chikazozikamwa, chero mutauri ezvinhu rakagadzirirwa yakananga zvakawanda uchishandisa frequencies. goho chiratidzo, zvokudya kune shongwe siyana kungaita kuti kukanganisa inzwi. Saka, kana iwe kushandisa kuti mutauri maitikiro zvakare pasi pake, ipapo kurira mufananidzo zvichabviswa akavhiringika. Kana kakawanda hahusvikirwi, ipapo muridzi hurongwa achagona kutarisana kwete chete isina kururama inzwi, asi pamwe kukundikana mukuru-chidhayinamo. Last kungoti haana kukwanisa kutsigira munhu nokushanda kwadzinoita yakadaro.

Under kwomuzvarirwo ezvinhu, mashandiro mukuru-kakawanda vakurukuri - kutamba ruzha chete panguva pamatunhu frequencies. Low-kakawanda acoustic hurongwa ushande voga. Dzimwe nguva kunyange yakatangwa dzakasiyana-siyana mufambi mupanda. The Ndozvakaitawo avhareji maitikiro mitinhimira. Vari zvokudya chete kumutauri, chinoshamisa pakati zvenguva frequencies.

Naizvozvo, nokuti yepamusoro playback mimhanzi Makwara mumotokari yako inofanira dzinounzwa zvimwe frequencies nokuvanamata mukanyatsochengeta kusaruraude vakurukuri. Nokuti ichi chinangwa uye kudikanwa Crossover acoustics.

pamasikiro mudziyo uri nyore. Izvi zviviri Frequency Sefa ukashanda sezvinotevera. Saka, kana kakawanda kupatsanurwa 1000 Hz, mumwe filters vaviri vachava govera frequencies pazasi mufananidzo uyu. The Sefa yechipiri achashanda pamwe kakawanda bhendi pamusoro chiratidzo. Filters vane mazita avo. Low-vanopfuura chakagadzirirwa kushanda yakaderera frequencies kusvika 1000 Hz. High-vanopfuura pezvakaitwa chete frequencies iri kuwanda pamusoro 1000 Hz.

Maererano nenheyo iyi vari kushanda maviri-nzira mudziyo. Zvisinei, muna wanhasi, pane-nzira nhatu Crossover. Musiyano mukuru pano - ndiyo imwe Sefa, anokwanisa kubata svikiro frequencies kubvira 600 Hz kusvika 1000 Hz.

More inonzwika apo mashoko ekuteerera kakawanda hova uye zvokudya navo unoenderana vakurukuri frequencies izvi zvinotisvitsa inzwi nani mukati motokari.

Technical zvinhu crossovers

Most ano mano vari inductors uye capacitors. ukoshi zvigadzirwa akaumba zvichienderana nhamba uye unhu mukugadzira zvinhu izvi.

Nei capacitor uye Coil chikamu Crossover nokuda nevakurukuri? Izvi zvinonyanya nyore chitundumuseremusere zvikamu. Ivo inexpensively kukwanisa kugadzirisa frequencies siyana. The capacitor anogona govera uye dzinoona dzakakwirira kakawanda, asi coils unoshanda yakaderera frequencies. Manufacturers nounyanzvi kushandisa zvivako izvi uye akaita zvayakaita nyore asi ichibudirira mudziyo.

Kuwanda reactive zvinoriumba kunokanganisa inogona filters: 1 - Shandisa chimwe chinhu, 2 - maviri zvinhu. Zvichienderana nokuwanda reactive zvinoriumba uyewo Crossover redunhu hurongwa filters panguva frequencies dzakasiyana vasiri akakodzera makwara chaizvo. Inogona vaifungidzira: zvikuru redunhu riri reactive okunze, nani crossovers mukurukuri achataura dzinobvisa chiratidzo. filtration Zvirongwa vane mamwe maitiro. Izvi vanonzi "yakatenuka kudzikira." Mune mamwe manzwi, zviri nehanya. Zvichienderana mwero "steepness kuti kudzikira", vose zvigadzirwa kutengeswa inogona kukamurwa muenzaniso wokutanga, giredhi wechipiri, wechitatu uye wechina.

Active uye pusa midziyo

Pusa Crossover nokuti acoustics - ndiwo inonyanya zvichachipedza. Aigona kakawanda kuwanikwa pamisika nhasi. Sezvo zita rinoreva kuti mudziyo uyu havadi wokuwedzera simba zvitengeswa. Naizvozvo, muridzi wemotokari achava anokurumidza zvikuru uye zvive nyore kuita kugadzwa gudzanzwi. Zvakaipira boka iri mano kuti nyore haisi nguva dzose runovimbisa yepamusoro.

Nokuda pusa wedunhu hurongwa anotora chikamu simba nokuda nokushanda firita. Panguva iyo reactive zvinoriumba kushandura danho kusuduruka. Sezvingatarisirwa, izvi hazvisizvo zvakakura drawback. Zvisinei, izvozvo rikasaita sezvo dzakaonda sezvinobvira kuita equalization. Kushaikwa hakuna kushingaira Crossover. Chokwadi ndechokuti pasinei kupfuura kunzwisisa design, Audio Frequency aibuda kwavari nani yakasvinwa zvakanaka. Nokuda pamberi mudunhu hakusi chete zvakawanda Coils uye capacitors, asi semiconductors, Developers kusika yepamusoro Namano yakawanda tsindirana miganhu. Active Crossover haawanzopiwi kuwanikwa ari oga module. Zvisinei, chero gudzazwi zvine filters akadaro.

Sei kugadzira mudziyo nomazvo?

Kuti tiwane chemhando yepamusoro varurame motokari yako, unofanira kusarudza zvakanaka kakawanda panguva iyo zvose zvakawandisa uchatemwa. Kana basa mano pamusoro mapoka matatu, unofanira kuwana mbiri chekawo-kure pfungwa. Wokutanga chiso chiratidzo muna siyana pakati yakaderera uye pakati frequencies. Wechipiri - musiyano pakati uye yakakwirira maitikiro.

How kuverenga maoko ako?

Crossover kukarukureta nokuti acoustics - chinhu chinokosha chichingoitwa. Asi hapana mugadziri vaisagona kubereka wakakwana gudzanzwi, iro aizokwanisa bereka yepamusoro kurira yakasiyana-siyana. For yakaderera maitikiro anoshandisa subwoofers. mid-siyana vakurukuri inoshandiswa svikiro. Asi kana yose kunzwisisa icharira, zvinogona kukonzera vamwe kuvhiringidzika. Ndokusaka pane Crossover mu acoustics - kune imwe mukurukuri kwaingova chiratidzo womumwe maitikiro. For nechirwere maitiro kana mumwe mugero wokutanga gudzazwi mudziyo zvakabatana, chiratidzo panoparadzana. Ndiyo firita. Pamwe nevakurukuri uchitova pusa crossovers, izvo anogadzirwa rikagadzirwa vagadziri.

Asi chii kana uchida vagovere kakawanda kurira pamusoro yakasiyana musimboti? Haufaniri kuva manually kuverenga chinhu - kwedu yepamusorosoro nguva yokuti kunyange nyore kushandiswa ikoko software. Saka nokuda Masvomhu izvi pane chirongwa Somuenzaniso Crossover Elements Calculator.

Danho rokutanga chirongwa chinotarisirwa nemishonga ukoshi LF uye RF vakurukuri, izvo kazhinji ndiyo 4 ohms. Uyezve jekiseni kakawanda kuti huchashandiswa anofanira kuparadzaniswa. Pakarepo tanga uye kurongeka Crossover. Zvadaro, achizviendesa bhatani uye kumirira kusvikira chirongwa zvichaguma. Somugumisiro, ruchadzokera chati Rinoratidza zvakafanira capacitors uye Coils nekuda kwezvavakaisa parameters.

kusarudza Features

The musika inopa nzira dzakasiyana-siyana mano kuti dzinosiyana quality, cost, mutengesi-zvakananga. Sarudza Crossover nokuti vakurukuri hakusi nyore - hamugoni chete kundotenga chinhu kuti aifarira. Kusarudza yakaitwa nevamwe vakurukuri. Fungidzira kuti iwe subwoofer outputs kamari kakawanda muna kuwanda 18 kusvika 200 Hz, reproduces midrange frequencies kubva 200 kusvika 1000 Hz, uye namatunhu - kubva 1000 kusvika 16000 Hz. In gudzazwi rino richigere-mu Sefa uye tinobereka frequencies ari zvinobva 18 kusvika 20,000 Hz. In chiitiko ichi, inoda-nzira nhatu Crossover, inokwanisa kushandisa mupise mu neeSultan izvi.

Uyewo, kana kusarudza Chenjerera uwandu zvisungo. Chimwe parameter chinokosha - Frequency siyana. Iva nechokwadi kuti kufungawo bandwidth. Multilayer mano kuva mukuru nehanya, anogona yekudyidzana kuvandudza mutsindo unhu.

mhedziso

Saka, takawana kuti Crossover ndizvo uye chii chinosara nayo anoita. Sezvaunogona kuona, ichi ndicho zvikuru chinhu ichocho chinokosha mumotokari Audio hurongwa.
