I-Stethoscope Yemakrofoni Yodonga Yokulalela Ngokucashile Ezindongeni
Ukusetshenziswa Komkhiqizo
Incazelo
Lezi zi-transducer ezimbili zamandla ezilalela ngodonga yizona ezibuyekezwe kakhulu emikhiqizweni efanayo kulezi zinsuku, ezinganika umlaleli ulwazi olucacile lomsindo abazolwazi. Lesi yi-amplifier ekhethekile ezozwa umsindo omncane kakhulu ezintweni eziqinile njengodonga, ukuze ulalele okwenzekayo ngakolunye uhlangothi. Imakrofoni yokuxhumana iyiphinikhodi eyenziwe ngobumba eyenzelwe ngokukhethekile ukuguqula ukudlidliza kube umsindo ozwakalayo. Inama-transducer amabili anamandla ndawonye ahlanganisa idivayisi yokuqapha eyingqayizivele ukuze kuvunyelwe amaphoyisa, amajele njalo njalo.

Ukulawulwa kwekhwalithi okuqinile ukuqinisekisa ukuthi umkhiqizo uhlala isikhathi eside futhi opharetha usebenza ngokuphepha.
Ngineminyaka engaphezu kwengu-10 yesipiliyoni embonini ye-EOD, imishini yokulwa nobuphekula, idivayisi yobunhloli, njll.
Sikhonze amakhasimende angaphezu kwamazwe angu-60 emhlabeni jikelele ngobungcweti.
Ayikho i-MOQ yezinto eziningi, ukulethwa okusheshayo kwezinto ezenziwe ngokwezifiso.
