Sei tichida crossovers muchikamu acoustics?
Zviri mukati
Paunenge uchiisa yemazuva ano stereo system mumotokari, muridzi anofanirwa kusarudza iyo chaiyo crossover. Hazvina kuoma kuita izvi kana iwe ukatanga kujairana kuti chii, icho chinoitirwa, uye sechikamu cheicho hurongwa hwemukurukuri huchashanda.
Chinangwa
⭐ ⭐ ⭐ ⭐ ⭐ Crossover chishandiso chakakosha muchimiro chemutauri system, chakagadzirirwa kugadzirira inodiwa yakavanzika renji kune yega yega yevatauri vakaiswa. Iwo ekupedzisira akagadzirirwa kushanda mukati memamwe ma frequency range. Kubuda kweiyo frequency yechiratidzo chakapihwa mutauri kunze kwerenji kunogona kutungamira, zvishoma, kukanganisa kweizwi rakadhindwa, semuenzaniso:
- kana yakaderera frequency yakashandiswa, mufananidzo wekurira unozokanganiswa;
- kana yakawandisa frequency yakashandiswa, muridzi weiyo stereo system achasangana kwete chete nekukanganiswa kwenzwi, asiwo kutadza kweiyo tweeter (tweeter) Anogona kungotadza kumira iyi nzira yekushanda.
Mumamiriro ezvinhu akajairwa, basa re tweeter ndere kubereka chete yakakwira-frequency ruzha, yakaderera-frequency, zvichiteerana, yakaderera. Iyo yepakati-renji bhendi inodyiswa kune yepakati-woofer - mutauri anotarisira ruzha rwepakati-renji mafrequency.
Zvichienderana nezviri pamusoro, kuitira kuburitsa odhiyo yemotokari nemhando yepamusoro, zvinodikanwa kuti usarudze mabhendi akakodzera uye woaisa kune chaivo vatauri. Kugadzirisa dambudziko iri, crossover inoshandiswa.
Crossover mudziyo
Zvimiro, iyo crossover inosanganisira peya yemafirita mafirita anoshanda sezvinotevera: semuenzaniso, kana iyo crossover frequency yakaiswa ku1000 Hz, imwe yemafirita ichasarudza ma frequency pazasi ichi chiratidzo. Uye chechipiri ndechekugadzirisa chete frequency bhendi inodarika iyo yakataurwa. Iwo mafirita ane mazita avo: yakaderera-pasi - yekugadzirisa mafambiro ari pasi pechiuru hertz; hi-pass - yekugadzirisa mafambiro pamusoro pechiuru chehertz.
Saka, nheyo iyo nzira mbiri-crossover inoshanda yakaratidzwa pamusoro apa. Kune zvakare matatu-nzira zvigadzirwa pamusika. Musiyano mukuru, sekureva kwazvinoreva, ndiyo sefa yechitatu inobata yepakati frequency bhendi, kubva kumazana matanhatu kusvika kuzviuru zvishanu hertz.
Muchokwadi, kuwedzera ruzha bhendi kusefa machanera, uye wozodyisa ivo kune vatauri vakakodzera, zvinotungamira kune zviri nani uye zvechisikigo kuberekana mukati memotokari.
Technical features
Mazhinji emazuva ano crossovers ane inductors uye capacitors. Zvichienderana nehuwandu uye kunaka kwekugadzirwa kwezvinhu izvi zvinogadziriswa, mutengo wechigadzirwa chakapedzwa unotarwa Sei bandpass crossovers ichisanganisira coils uye capacitor? Chikonzero ndechekuti idzi ndidzo dzakareruka reactive zvinhu. Ivo vanogadzira ma frequency akasiyana eiyo odhiyo chiratidzo pasina kuoma kwakawanda.
Macapacitor anogona kupatsanura uye kugadzirisa ma frequency akakwira, nepo macoil achidikanwa kudzora ma frequency akaderera. Kunyatsoshandisa izvi zvivakwa, semhedzisiro, unogona kuwana yakapusa frequency sefa. Izvo hazvina musoro kunyura mumitemo yakaoma yefizikisi uye kupa mafomula semuenzaniso. Vaya vanoda kujairana neiyo theoretical nheyo mune zvakadzama vanogona kuwana nyore ruzivo mumabhuku kana paInternet. Zvakakwana kuti nyanzvi dzeprofile dzizorodze mundangariro musimboti wekushanda kweLC-CL mhando network.
Nhamba yezvinhu zvinogadzirisa zvinokanganisa simba re crossover. Nhamba 1 inoreva chinhu chimwe, 2 - zvakateerana, zviviri. Zvichienderana nehuwandu uye chirongwa chekubatanidza chezvinhu, sisitimu inoita kusefa kweasina kufanira ma frequency eimwe chiteshi munzira dzakasiyana.
Zvine musoro kufunga kuti zvimwe zvinogadzirisa zvinhu zvakaiswa zvinoita kuti kusefa zviite nani. Iyo isingadiwe frequency kusefa chirongwa cheimwe chiteshi ine hunhu hwayo hunodaidzwa kuti roll-off slope.
Mafirita ane hunhu hwekudimbura zvisingadiwe zvishoma nezvishoma, kwete ipapo ipapo.
Inonzi sensitivity. Zvichienderana nechiratidzo ichi, zvigadzirwa zvakakamurwa muzvikamu zvina:
- yekutanga odha mhando;
- mhando dzechipiri-odha;
- yechitatu odha mhando;
- yechina yemhando yemhando.
Kusiyana pakati pekushanda uye passive crossovers
Ngatitange kuenzanisa ne passive crossover. Zvinozivikanwa kubva pakuita kuti passive crossover ndiyo yakajairika uye yakajairika siyana pamusika. Zvichienderana nezita, unogona kunzwisisa kuti zvisizvo hazvidi rimwe simba. Saizvozvo, zviri nyore uye nekukurumidza kuti muridzi wemotokari aise midziyo mumotokari yake. Asi, zvinosuruvarisa, kumhanya hakusi nguva dzose kuvimbisa kunaka.
Nekuda kweiyo passive musimboti wedunhu, sisitimu inoda kutora imwe simba kubva kune sefa kuti ive nechokwadi chekushanda kwayo. Muchiitiko ichi, zvinhu zvinogadzirisa zvinowanzochinja kuchinja kwechikamu. Ehe, iyi haisiriyo yakakomba dhizaini, asi muridzi wacho haakwanise kugadzirisa-tune ma frequency.
Active crossovers inokubvumira kuti ubvise iyi drawback. Icho chokwadi ndechekuti, kunyangwe iwo akaomesesa zvakanyanya pane akasarudzika, iyo odhiyo rwizi inosefa zvirinani mavari. Nekuda kwekuvapo kwete chete coils uye capacitor, asiwo mamwe semiconductor zvinhu, vagadziri vakakwanisa kuderedza zvakanyanya saizi yechishandiso.
Ivo havawanzo kuwanikwa semidziyo yakaparadzana, asi mune chero mota amplifier, sechikamu chakakosha, pane inoshanda sefa.

Isu tinopawo zano kuti uzvizive nemusoro unofambidzana "Maitiro ekubatanidza nekuisa Twitter nenzira kwayo".
Maitiro ekugadzirisa
Kuti uwane yepamusoro-yemhando yemota audio semhedzisiro, iwe unofanirwa kusarudza iyo chaiyo cutoff frequency. Paunenge uchishandisa inoshanda-nzira nhatu crossover, maviri cutoff frequency anofanirwa kutsanangurwa. Yekutanga poindi ichaisa mutsetse pakati pepasi nepakati frequency, yechipiri - muganhu pakati pepakati nepamusoro. Usati wabatanidza crossover, muridzi wemotokari anofanirwa kugara achiyeuka kuti zvakakosha kunyatsosarudza maitiro emutauri.
Hazvina mhosva kuti ivo vanofanirwa kupihwa mafrequency avasingagone kushanda semazuva ese. Zvikasadaro, hazvizongotungamira mukuderera kwemhando yenzwi, asiwo nekuderera kwehupenyu hwebasa.
