Qhov kev tsim kho feem ntau yog muab rau William J. Toulis thaum lub sijhawm the lig 1950s.
Dab tsi yog transducer siv rau?
Ib tus transducer txhais tau tias yog khoom siv los hloov lub zog ntawm ib daim ntawv mus rau lwm qhov. Qhov tseem ceeb nyob rau hauv cov ntawv no yog lub electromechanical transducer rau hloov hluav taws xob hluav taws xob mus rau hauv txhua yam zog, thiab vice versa. Muaj ntau hom transducers.
Tus thawj transducer lub npe yog dab tsi?
Transducers yog siv hauv kev sib txuas lus hauv hluav taws xob los hloov cov teeb liab ntawm ntau yam ntawm lub cev mus rau hluav taws xob teeb liab, thiab rov ua dua. Hauv qhov piv txwv no, thawj qhov hloov pauv tuaj yeem yog a microphone, thiab tus thib ob transducer tuaj yeem yog tus hais lus.
Puas yog tus transducer tiag?
Ib tug transducer yog ib yam khoom uas hloov ib hom zog rau hauv lub teeb liab nyeem tau. Ntau cov transducers muaj cov tswv yim uas tom qab ntawd hloov mus rau cov teeb liab hluav taws xob proportional. Cov khoom siv muaj xws li lub zog, lub zog, lub teeb, lub zog, txoj haujlwm, kev nrawm, thiab lwm yam khoom siv lub cev.
Vim li cas transducer siv hauv kev sib txuas lus?
No input transducer hloov qhov tsis yog hluav taws xob lub cev kom muaj nuj nqis rau hauv hluav taws xob teeb liab. Lub cev muaj nuj nqis xws li suab lossis lub teeb tuaj yeem hloov mus rau hauv cov khoom hluav taws xob xws li hluav taws xob lossis tam sim no los ntawm kev siv qhov hloov pauv no.
