Mbiri nehafu nzira marongerwo

Maseti egudzanzwi (magudzanzwi) agara akavakirwa pamusimboti wekubatanidza masipika ane hunyanzvi mukugadzirisa zvikamu zvakasiyana zveacoustic spectrum. Saka zvinoreva kukosha kweiyo pfungwa ye "loudspeaker", i.e. mapoka e (akasiyana) magudzanzwi (vashanduri) anopindirana uye anovhara iyo yakakura kwazvo bandwidth, ine yakaderera kukanganisa.

Kusiya yakaderera-bhajeti kana exotic single-way vatauri parutivi, ari nyore mutauri ari murairo wenyika mbiri. Inozivikanwa kune akawanda madiki madhizaini e-rack-moudhi pamwe neakanyanya kudzikama masipika, inowanzo sanganisira gumi nemaviri kusvika makumi maviri masendimita mutyairi wepakati anovhara bandwidth inosvika 12-20 kHz, uye tweeter inobata nepamusoro peiyo. yakatemerwa nekusangana kwehunhu (iyo inonzi crossover frequency). Tsanangudzo yaro inofunga nezve "zvakasikwa" maitiro uye kugona kwevatauri vega, asi pakupedzisira kazhinji mhedzisiro yezvinonzi electric crossover, i.e. seti yemafirita - yakaderera-pass yemidwoofer uye yakakwira-pass ye tweeter.

Yakadaro sisitimu, mune yekutanga vhezheni, ine imwe yepakati-woofer uye imwe tweeter, uchishandisa mhinduro dzemazuva ano, inobvumidza iwe kuti uwane simba rakawanda uye yakanaka bass kuwedzera. Zvisinei, kuguma kwayo kunotarirwa nemamiriro ezvinhu akaiswa pamutauriri wepasi-frequency. Saizi yemutauri uyu haifanire kudarika muganho wekugadzirisa kwakaringana kwepakati mafrequency (iyo yakakura mutauri, zvirinani inobata mabass, uye zvakanyanya kubata iyo yepakati mafrequency).

Kutsvaga imwe marongerwo

Iyo yemhando yepamusoro nzira yekubuda pane inogumira hurongwa hwetatuiyo inokubvumira kuti uwedzere zvakasununguka dhayamita yewoofer, nokuti midrange inotamirwa kune imwe nyanzvi - midrange speaker.

Zvisinei, pane imwe mhinduro inogona kuwedzera zvakanyanya miganhu yehutano hwemaviri ehurumende, kunyanya kuwedzera kukwanisa uye kushanda. Uku ndiko kushandiswa kwema midwoofers maviri (ayo, chokwadi, anoda vhoriyamu yakaenzana, saka anowanikwa mune vatauri vakasununguka). Iyo katatu yepakati-woofer dhizaini haichashandiswi, nekuda kwekuwanda kwakashata kwechikamu chekuchinja kwaizoitika pakati pevatyairi vekunze, kunze kweakisi huru yegungano. A sisitimu ine maviri midwoofers (uye imwe tweeter), kunyangwe iine huwandu hwevatyairi vatatu, ichiri kunzi nzira mbiri nekuti bhendi rakakamurwa kuita zvikamu zviviri nemasefa; ndiyo nzira yekusefa, kwete nhamba yevatauri, inotara "kujeka".

Nzwisisa nzira mbiri nehafu

Chirevo chekupedzisira chakakosha kunzwisisa kuti chinoshanda sei uye matsananguriro acho. hurongwa hwemashizha maviri. Iyo yakanakisa yekutanga ndiyo yakatsanangurwa nzira mbiri-nzira ine maviri epakati-woofers. Iye zvino zvakakwana kuunza imwe chete shanduko - kusiyanisa pasi-pass filtering ye midwoofers, i.e. sefa imwe yakaderera, muhuwandu hwemazana mashoma ehertz (yakafanana newoofer munzira yenzira nhatu), uye imwe yakakwirira (yakafanana neyakaderera-yepakati siyana mune maviri-nzira system).

Sezvo isu tiine mafirita akasiyana uye mashandiro awo, wadii kudaidza matatu-bhendi chirongwa?

Kwete kunyange nekuti vatauri pachavo vanogona kunge (uye kazhinji kazhinji, asi kure nekugara) vakafanana. Chokutanga pane zvose, nokuti vanoshanda pamwe chete mumhando dzakasiyana-siyana dzepasi pasi, izvo zvisiri zvemukati muhurongwa hwematatu. Muchirongwa cheviri nehafu, bandwidth inoparadzaniswa kwete muzvikwata zvitatu zvinobatwa "chete" nevashanduri vatatu, asi mu "mabhandi maviri nehafu." Iyo yakazvimirira "nzira" ndiyo nzira yetiweta, nepo imwe yepakati-woofer inofambiswa chikamu (bass) nevatauri vese uye chikamu (pakati) nemutauri mumwechete.

Pakati pevashanu vakasununguka vatauri vakasununguka kubva kubvunzo mumagazini "Audio" muboka rinonyatsomiririra mutengo we PLN 2500-3000, akawana.

pane imwe chete nzira nhatu dzekuvaka (yechipiri kubva kurudyi). Mamwe ose maviri nehafu (yekutanga nechipiri kubva kuruboshwe) uye maviri-nzira, kunyange zvazvo kugadzirisa kwevatauri vari kunze hakuna kusiyana nembiri nehafu. Musiyano unosarudza "patency" uri mukuchinjika uye nzira yekusefa.

Sistimu yakadaro ine "kugona" maficha enzira mbiri, maviri-midwoofer system, ine bhenefiti yakawedzerwa (kunyanya mumaonero evazhinji vanogadzira) yekudzikamisa midrange kugadzirisa kune mumwe mutyairi. inodzivirira dambudziko rambotaurwa rekuchinja kwechikamu. Ichokwadi kuti nepakati mbiri dziri pedyo pamwe chete, hadzifanirwe kunge dzakakura zvakadaro, ndosaka vamwe vanhu vachigadzirisa nzira yakapfava yenzira mbiri, kunyangwe kushandisa maviri mids.

Zvakakosha kuziva kuti zvose zviviri nehafu uye nzira mbiri, pane maviri midwoofers ane dhayamita (yakazara), semuenzaniso, 18 cm (inonyanya kugadziriswa), ine imwechete membrane nzvimbo munzvimbo. low frequency range semutauri mumwe ane dhayamita 25 cm (nzira yenzira nhatu inobva pamutauri akadaro) . Ehe, iyo diaphragm pamusoro haina kukwana, vatyairi vakakura vanowanzo kwanisa kuwedzera amplitude kupfuura madiki, izvo zvinowedzera kuwedzera kugona kwavo kwakaderera-frequency (kupi chaizvo huwandu hwemhepo iyo mutauri anogona "kupomba" mune imwe kutenderera, kuverenga. ) Pakupedzisira, zvisinei, vaviri vemazuva ano 18-inch vatauri vanogona kuita zvakawanda vachiri kubvumira dhizaini yakaonda yekabati zvekuti mhinduro yakadai yave kupaza marekodhi ekukurumbira uye kubvisa matatu-nzira dhizaini kubva muchikamu chepakati chemutauri.

Nzira yekuziva marongerwo

Hazvibviri kusiyanisa pakati penzira mbiri dzakashandisa mhando dzakafanana dzevatyairi sewoofers uye midrange drivers, uye nzira mbiri-nzira ine maviri midrange-woofers. Dzimwe nguva, zvisinei, zvakajeka kuti tiri kutarisana nemaitiro maviri-apo misiyano pakati pevatauri vaviri ichionekwa kubva kunze, kunyange zvazvo vane dhayamita imwechete. Gudzanzwi rinoita sewoofer rinogona kunge riine chivharo chikuru cheguruva (kusimbisa pakati pe diaphragm). Loudspeaker inoshanda senge midwoofer uye - yakareruka diaphragm, nezvimwe. a phase corrector iyo inovandudza kushandiswa kwepakati-frequencies (nekusiyanisa kwakadaro kwezvivakwa, zvingava kukanganisa kushandisa kushandiswa kwakafanana uye nzira mbiri). Izvo zvinoitikawo, kunyange zvisingawanzoitiki, kuti woofer yakakura zvishoma pane midwoofer (somuenzaniso, woofer ndeye 18 cm, iyo midwoofer 15 cm). Muchiitiko ichi, hurongwa hunotanga kutaridzika senzira nhatu kubva kunze, uye chete kuongororwa kwekushanda kwe crossovers (mafirita) kunotibvumira kuziva zvatiri kutarisana nazvo.

Chekupedzisira, kune masisitimu ane "patency" zvakaoma kutsanangura zvakajekazvisinei nekuziva ese maficha echimiro. Muenzaniso igudzanzwi, iro rinotanga kuonekwa sewoofer-midrange speaker nekuda kwekushaikwa kweyepamusoro-pass sefa, asi haisi diki chete, asi zvakare inogadzirisa yakaderera frequencies zvakanyanya kupfuura iyo inoperekedza woofer, nekuda kweiyo " predispositions" , pamwe chete nenzira yekushandiswa mumba - somuenzaniso, muimba duku yakavharwa.

Uye zvinokwanisika here kufunga nezvematatu-nzira chirongwa umo iyo midwoofer haina kusefa nepamusoro-soro, asi maitiro ayo anopindirana, kunyangwe pane yakaderera crossover frequency, ine maitiro ewoofer? Haisi nzira mbiri nehafu here? Aya ndiwo mafungiro ezvidzidzo. Chinhu chikuru ndechekuti isu tinoziva kuti iyo topology yehurongwa uye maitiro ayo ndeapi, uye kuti sisitimu yacho yakanyatso kurongeka.
