Qhov tseem ceeb tshaj plaws ntawm kev kuaj ultrasonic yog ultrasonic transducer. Rau tej ultrasonic daim ntawv thov, qhov kev xaiv ntawm qhov tseeb hloov pauv yog qhov tseem ceeb tshaj plaws theem. Tus lej uas cuam tshuam rau qhov tshwm sim yog cov khoom siv, ntsuas thiab cov xwm txheej siv rau kev txuas thiab kev teeb tsa.
Nyob ntawm daim ntawv thov tshwj xeeb nws yuav tsum muaj rau; lub tshuab transducer tuaj yeem raug xaiv raws li nws cov kev nkag siab thiab kev daws teeb meem. Lub peev xwm ntawm lub tshuab hloov mus kuaj kom pom qhov me me tsis xws li hu ua nws qhov kev nkag siab zoo qhov twg yog qhov sib cais mus rau ntawm ob lub teeb liab uas tsim los ntawm ob lub zog thaum kaw thiab yuav muab txiav lossis sib piv rau cov nqaj tau hu ua kev daws teeb meem. Ib lub tshuab xa hluav taws xob ntau heev pub rau daws qhov teeb meem tsis xws luag tsuas yog pab ua kom luv luv ntawm lub ntsej muag muaj mem tes.
Tus tsim cov cuab yeej no tseem tuaj yeem ua cov hloov pauv uas yog tsom rau kev txhim kho kev daws teeb meem thiab rhiab, qhov kev xaiv loj ntawm polarized ceramic composition, polymers, cov khoom sib xyaw piezo thiab cov khoom sib xyaw ua ke kom qhov kev ua tau zoo ntawm lub tshuab hloov pauv tuaj yeem hloov kho raws li qhov yuav tsum tau ua.
Lub Hom Phiaj
Qhov ntsuas suab yog ib lub suab uas yog siab dua cov qib ntawm tib neeg lub rooj sib hais. Txawm hais tias feem ntau ntawm cov hloov khoom tsim hluav taws xob uas muaj ntau zaus tshaj 200 KHz, qhov cuam tshuam pib ntawm tsuas yog 20 KHz xwb. Cov suab no zoo li cov suab zoo li nthwv-vuag tab sis muaj lub suab ntab uas yog qhov luv heev. Cov ntsiab lus tseem ceeb no ua rau cov vuag no zoo dua rau txhawm rau txhawm rau ua txhaum me.
Qhov tseeb, nws yog cov luv ntab luv luv uas ua rau lub zog hloov ultrasound ua cov khoom loj muaj txiaj ntsig zoo hauv kev tshuaj xyuas, tshawb pom, ntsuas thiab ntsuas ntawm cov khoom sib txawv.
