Umlinganiselo wokulinganisa we-Ultrasonic tshintshela kwikhabhinethi yokukhupha umvavanyi
Isandla esiphathwayo esiBanjelwe kwiPd Detector yokukhupha inxenye yoMvavanyi
Isixhobo samkela uyilo oluphathwayo, olunokuthi luhlolisise kwaye lubone ngokuthe ngqo kwiqokobhe yekhabhinethi yokutshintsha ngaphandle kwempembelelo okanye umonakalo ekusebenzeni kwekhabhinethi yokutshintsha. Ngexesha elifanayo, isignali elinganisiweyo ingagcinwa kwaye iphindwe kwakhona kwikhadi leTF ukuze kube lula ukubhekisela, kwaye ii-earphone ezibonelelweyo zingasetyenziselwa ukuva isandi sokukhutshwa kombane.

Isicelo seSeti yoVavanyo lokuKhupha ngokungaphelelanga
Ukukhutshwa okuyingxenye ngokuqhelekileyo kwenzeka apho ukugquma kocingo konakaliswe. Inokubangela iisekethe ezimfutshane kunye nomlilo, okukhokelela ekungaphumelelini okutshabalalisayo. Eyona meko iyingozi kakhulu ukwahlukana kakubi kwangaphandle ngokubanzi, kunye nokuwa ngokuthe ngcembe kukhokelela ekungaphumelelini kwezixhobo ezingalindelekanga. Ngoko ke, ukujongwa okuqhubekayo okanye rhoqo kwezixhobo eziphezulu ze-voltage kunye nokufumanisa ngexesha lokukhutshwa okuyingxenye kubaluleke kakhulu.
Ii-detectors zokukhupha inxenye zisetyenziswa ngokubanzi kumlinganiselo wokukhutshwa kwenxalenye yeemveliso zombane ezine-voltage ephezulu njengeziguquli, iziguquli, iiswitshi ezinombane ophezulu, izibambisi ze-zinc oxide, iintambo zombane, njl.njl.
