Atatu njira ndi ziwiri okamba: zizindikiro ubwino, kusiyana

Mu msika lero okamba ndi kuperekedwa mu uthunthu mwachilungamo lalikulu. zida Izi ndi zosiyana Chrixitu mu kuchuluka kwa (chida, zoimbaimba, situdiyo, etc.) mogwirizana ndi specifications ndi maonekedwe a alumikizana makhalidwe ena ambiri. The chizindikiro chofunika kwambiri kuonedwa mu malo oyamba, chiwerengero "mipiringidzo" ku kachitidwe. Malinga ndi muyezo uyu, wolemekezeka one-, three- ndi ziwiri okamba. Kodi amasiyana mzake ndi zomwe dongosolo bwino, tidzayesetsa kuti m'nkhani ino.

Pafupipafupi phokoso

ziwalo kumva amatha kuzindikira phokoso la pafupipafupi 20 20,000 Hz. Choncho khalidwe la nyimbo amadalira luso la zida za kulenga khirisipi phokoso mafunde osiyanasiyana anapatsidwa. Chifukwa chaichi, mu wokamba anayamba monga okamba kuti kubereka otsika kwambiri (20-150 Hz), sing'anga (100-7000 Hz) ndi mkulu (5-20 zikwi. Hz) mafurikwense. Pa nkhani imeneyi, panali:

1. SSB dongosolo, kumene lonse pafupipafupi osiyanasiyana amapanga okamba nkhani.
2. okamba ziwiri, amene ali okamba awiri: mmodzi kusewera nyimbo pa sing'anga ndi mafurikwense otsika, ndipo chachiwiri - yekha pamwamba.
3. Atatu kanjira zida - chifukwa kusewera phokoso aliyense osiyanasiyana limafanana ndi osiyana "mzati".

Pali zida ndi zambiri zomangirazo, aliyense wolankhula imabereka oganiza wina pafupipafupi osiyanasiyana. Wotchuka kwambiri ndi lupanga ndi atatu kanjira dongosolo - iwo ali kwambiri angakwanitse ndipo pa nthawi yomweyo kupereka kwambiri phokoso khalidwe.

Ubwino wa okamba ziwiri

okamba ziwiri ndi otchuka pakati ziziyenda. Iwo amapereka akadakwanitsira phokoso khalidwe nthawi yomweyo ndi mtengo wololera. Chifukwa cha kukula kwa ziwiri luso zowulutsira mwachangu osamukira zida zitatu gulu, koma afala chifukwa cha ubwino wake:

1. Kamangidwe yosavuta, zomwe zimatithandiza unsembe ndi kasinthidwe.
2. The digiri yapamwamba ya kugwirizana pakati okamba, chifukwa mu kuzikonzanso Phokoso khalidwe.
3. The kwambiri zachilengedwe, "moyo" phokoso.

Zipangizo ziwiri kanjira ali okamba awiri - yoimba ndi treble. Bass wokamba umabala phokoso mu ranges otsika ndi m'ma, ndi RF - Only mkulu. Chifukwa iyi ya dongosolo ayenera Intaneti yosavuta kusinthanitsidwa.

NKHANI zida zitatu gulu

Atatu njira wokamba ndi osiyana ndi dongosolo kale anafotokoza phokoso kwambiri. Zipangizo madongosolo otero doukomplektovyvaetsya dalaivala midrange, limene likutengera otchedwa "okhudza malo" mudziwe amalenga akuzinga phokoso. Komanso, chifukwa kulekana kwa ntchito zida wakhala ang'onoang'ono. Wachisoni khalidwe machitidwe atatu gulu ndi mtengo. Ndi nthawi ziwiri kapena zitatu kuposa wa oyankhula ziwiri. Komanso atatu njira kusinthanitsidwa zowulutsira kumafuna unsembe - zovuta Zosefera pafupipafupi. Kukhazikitsa zida zoterezi zimamva kwambiri, kapena kukwaniritsa kugwirizana kwa okamba sizigwira ntchito.

okamba kusiyana

dongosolo lililonse lamayimbidwe tichipeza okamba (MF, LF ndi RF), imathandiza zida, amplifiers chizindikiro zingwe wailesi, ndi malo athandizira. Kusefera zipangizo ndi udindo kulekana kwa mbendera zomvetsera m'magulu angapo. Lamayimbidwe wapawiri gulu fyuluta pafupipafupi ukugawa pawiri "gawo" - kuti 5-6 zikwi Hz ndi pamwamba 6 kHz .. zipangizo zitatu njira zambiri zili ndi crossovers - chosinthika Zosefera pafupipafupi zomwe kugawa buku osiyanasiyana mu magawo atatu.

Zipangizo zonse lamayimbidwe akhoza kukhala yogwira kapena kungokhala chete. Mbali yoyamba lililonse Makaniko ali okonzeka ndi osiyana chizindikiro mkuzamawu. njira facilitates mayikidwe a emitters, kuchepetsa wonse mtengo dongosolo. Komabe, ndi zovuta kuchuluka kwa utumiki, unsembe ndi kasinthidwe koyamba. amplifiers osiyana zambiri wowonjezera ya zipangizo zitatu njira.

Coaxial ndi chigawo okamba

Kuti lidzalira ngati okamba three- kapena ziwiri mu galimoto zimatengera mtundu wa okamba amene coaxial ndi chigawo. Woyamba ndi umodzi monolithic dongosolo limene radiators amaphatikizidwa mkulu, sing'anga ndi mafurikwense otsika. njira Izi zimapangitsa kuwomba kwambiri mbali. Choncho zida amenewa ntchito monga zowonjezerazo ndi makamaka magalimoto ang'onoang'ono. okamba chigawo ndi emitters, sipangakhalenso anakonza m'malo osiyanasiyana. Chifukwa izi n'zotheka kukwaniritsa akuzinga phokoso Komabe, zovuta unsembe ndondomeko. Komanso, chifukwa unsembe zosayenera siteji phokoso adzakhala sakanikira ndithu. kachitidwe chigawo anaika mu magalimoto ndi mkati lalikulu.

Mtengo nkhani

Monga tanenera poyamba, ziwiri wokamba adzakhala mtengo kwambiri kuposa khazikitsa zida zitatu gulu. Pali zifukwa ziwiri:

• yocheperako kuchuluka zida - amafuna okamba awiri okha, pazipita amplifiers awiri ndi fyuluta imodzi;
• losavuta unsembe - kusonkhanitsa ngati kachitidwe akhoza kukhala paokha, anali ndi nzeru zofunika m'munda wa magetsi.

The zikuchokera dongosolo atatu njira chikuphatikizapo zida chipangizo, mtengo umene ndi apamwamba kuposa mtengo zipangizo ochiritsira. Komanso, ngati mwaganiza kukhazikitsa okamba amenewa, muyenera kupempha thandizo kwa akatswiri - palibe wapadera zipangizo chingwe ndi dongosolo woonda khutu-wokwera lidzalira chimodzimodzi monga okamba ziwiri. Izi ndi yankho waukulu funso la kusiyana okamba ziwiri kuchokera atatu njira.
