Acoustic amsindise ucingo: iimpawu kunye neentlobo

Ukuphumeza isandi ezikumgangatho ophezulu xa ufaka le kumqhubi, kufuneka sinikele ingqalelo onke amacandelo - izithethi, yokukhulisa, yaye, ke, iintambo isithethi. Fumana umculo phezulu kwinkqubo imali ziya kusebenza xa usebenzisa i wire eqhelekileyo. Wasikhusela cable - yiloo nto kufuneka ukuba uxhumane lwemvelaphi izixhobo umqondiso ukudlala. Kungenjalo wena kufuneka ukumamela wengxolo esidlo phakathi iingoma.

Somlomo cable

Modern isithethi cable a kwezinikezeli ezimbini okanye ngaphezulu wamandla ombane, zibekwe Ukuqhela Polyvinyl chloride, teflon, lyu kunye nezinye izinto polymeric. Iingcingo kagesi ncam, kodwa iphawulwa imibala ezahlukeneyo, ukwenzela ukuba umsebenzisi akenzi umva ezichaseneyo ngexesha uxhulumaniso, ubunye izixhobo. Yobhedu isebenza izinto base. It has resistivity zombane liphantsi evumela ukuba ukufikelela kwizinga eliphezulu sound. Nangona kunjalo, ngexesha kungekabekwa intambo inokuwisa imigca amandla kufutshane. Ngenxa yale mhlaba otsalayo kuya kuvela, imisinga eddy, leyo ukunciphisa kakhulu izinga lesandi.

Ukuze siphephe le ngxaki, sebenzisa ucingo okhethekileyo - wasikhusela. Loo intambo umntu ukukhuselwa ngokukhethekileyo ngesinyithi okanye iplastiki, nto leyo uhlobo 'umfanekiso' ekuphazanyisweni electromagnetic.

Types of isithethi neengcingo

Ukuze ngentambo eziqhelekileyo wasikhusela ukumelana ukukhuselwa uphazamiseko, oko kufuneka adityaniswe emhlabeni, ie emhlabeni. Kwezinye iimeko, esi senzo nje akunakwenzeka. Yiyo loo nto elaqanjwa intambo elungeleleneyo. Ukuba umqhubi oluqhelekileyo ekhoyo kuphela engundoqo enye "core 'eli liyithweleyo uphawu engundoqo, ngoko ababini kubo intambo elungeleleneyo - ashushu nabandayo. Zombini athwale ulwazi olufanayo, kodwa "kufana" ezahlukeneyo. Ukusebenza oku kuxhomekeke kumgca lomncono kwizinti.

Ulime ukhuseleko elungileyo Star okane iintambo, apho ngababini ezimbini "iintonga 'zodwa kwaye enxulumene ngaxeshanye kunye namanye, kunye oku kuzuzwa kwinqanaba eliphezulu yokuzikhusela. Iingcali ukuchonga ekuthiwa-wire conductive wasikhusela ngeplastiki. Olu hlobo cable olusebenzayo phezu imigama emifutshane, umzekelo, ngexesha lofakelo kwinkqubo kwisithuthi odiyo.

Xa iqela eyahlukileyo ungahlula iintambo microphone, apho ukhuselo senziwe izinto womluki. Kodwa ubhetyebhetye kwaye inika ukhuselo engcono ucingo kunye screen oyiphanzise.

Iingcingo nokhuseleko ngefoyile ye

Neengcingo nokhuseleko ngefoyile ye phakathi izinto ezahlukeneyo apho kwikhusi kunye nohlobo qhina. Xa iyonke kukho iindidi ezine wokhuseleko electromagnetic:

• ngefoyile ye ubhedu okanye aluminiyamu screen - inika abaqhubi ngokhuseleko elungileyo evela uphazamiseko magnetic, kodwa basengozini phinda nokujikeleziswa (breaks nokhuselo kunye neentanda);
• umnatha ubhedu qhina - ucingo, indawo amsindise ngale ndlela, udala nkuselo ekuphazanyisweni, kodwa ixabiso eliphezulu kakhulu (ezisetyenziswa izixhobo zobungcali);
• qhina isantya ngobhedu okanye enye base ngesinyithi - ikheyibhile ngenkankulu sengozini lingonakali koomatshini nokhuseleko elungileyo ekuphazanyisweni.

Uhlobo lwesine intambo kunye screen combined, leyo oludibanisa iimpawu luncedo xa ngefoyile ye eqinileyo, kunye neendidi ezahlukeneyo braids. Ahluke kwixabiso avareji, kunye neentlobontlobo enkulu kumanqanaba aphezulu yokuzikhusela.

Kweelana umqhubi nomgangatho sound

impembelelo tsotsololo izinga lesandi siyakwazi ukumelana zombane ethile nombhexeshi. Line ukumelana ive luxhomekeke ezininzi parameters - umbandela, indawo cross somhlathi kunye nobude le ntambo. Umgangatho kakuhle epholileyo esikwaziyo ukunikeza ucingo lobhedu kunye ngefoyile ye uvikele. Ngaloo phantsi umaleko yokwambathisa kufuneka imisonto-20 ubuncinane. Ukuba indawo cross-somhlathi ayidluli 2.5 mm ^2, kunye nobude cable kwiimitha ezi-3, ngoko ke ukumelana iya kulingana zero. Ngako oko, umgangatho isandi kunye ucingo kuya kuba ngcono.

parameters umqhubi ube nefuthe zokusebenza. Umzekelo, Iingcingo elide kufuneka capacitance ephakamileyo inductance, nto leyo idala umthwalo owongezelelweyo kwi amp.

zikagesi mninzi

Mninzi cable umqhubi eqhelekileyo, iziphelo lwazo izihlanganisi ekhethekileyo uqhagamshelwano izixhobo okanye iibhloko. iintambo uqhagamshelwano wasikhusela, Iingcingo abanye nshita imigca ive oluqhelekileyo. Ngokukodwa, umgangatho isandi nto ixhomekeke kuhlobo zokhuselo, kunye nokuveliswa kwezixhobo. Ukumisela elayibrari ube nokufaka:

• SSS HI ISIPHELO SP - zibonakaliswe njenge umgca ive ezenziwe ngobhedu alekwe ngesilivere, ke ezinako ukudala umgangatho ilungileyo yesandi.
• EMT OFC SC - kwesifinyezo osetyenziswayo ukubonisa iingcingo OFC nje nganto ummeli sangaphambili umgangatho uphawu ngesondo.
• AHpsc 16 GA - nje iingcingo ezikumgangatho ophezulu.

Ukuba ukhangela iintambo, ekwaziyo ngaphandle ubugqwetha ukuba angadlulisela umqondiso, ngoko kufuneka sinikele ingqalelo izinto eyenziwe ngokupheleleyo ngesiliva. Iimveliso ezinjalo amakhulu ezixabisa zeedola imitha 1 nganye, kodwa umgangatho umqondiso ezosulela ngabo ayinakuze ithelekiswe.

ezintambo balahleke

Indawo ekhethekileyo emarikeni nezixhobo ive ithatha wasikhusela wire balahleke. Le umqhubi phantsi umaleko ukwambathisa imisonto eziliqela munye. Zinelungelo kwiqela lokulungileyo phezu intambo single-core:

1. luthambe High - iingcingo azikho senze izinto ezoyikekayo, amathuba kunye nezinye umatshini.
2. iilahleko ezincinci yangoku - ngenxa transmission uphawu ngu eziliqela "intonga".
3. usuke High - iinkqubo ezenzeka kule mizuzwana yokuqala emva kokuba wesekethe elifutshane (xa wayicima iswitshi iimo, umzekelo) akukho isiphumo.
4. ukuthembeka High kunye nobomi obude - ubomi iimveliso ezifana iphezulu kakhulu olulodwa-core.

Olu hlobo ezintambo aye neengxaki ezithile. Chief phakathi kwabo - iindleko eziphezulu. Ngoko ke, ixabiso ucingo-ezimbini umgca amsindise besukelana 1500 zemithi yokujika. Ukongeza, ezi azizikhokelo ezingenzelwanga ukuba zisetyenziswe networks ophezulu rhoqo.
