1. Piezoelectric nyhuv. Piezoelectric ceramics yog ib hom tshwj xeeb ntawm cov khoom siv ceramic nrog cov nyhuv piezoelectric. Cov nyhuv piezoelectric hais txog qhov tsis sib xws ntawm cov nqi tsim tawm thaum piezoelectric ceramics deformed los ntawm sab nraud quab yuam, ua rau muaj kev sib cais ntawm qhov sib txawv thiab cov nqi, yog li tsim cov teeb liab voltage. Cov nyhuv piezoelectric yog lub hauv paus rau piezoelectric ceramics los hloov lub zog txhua yam rau hauv hluav taws xob.
2. Cov qauv ntawm piezoelectric ceramic transducer. Lub piezoelectric ceramic transducer muaj piezoelectric ceramic daim hlau, embedded electrodes, thiab mechanical support structures. Ntawm lawv, daim ntawv piezoelectric ceramic yog cov ntsiab lus tseem ceeb, kos nrog cov khoom siv hluav taws xob rau kev sau thiab xa cov nqi, thiab cov qauv kev txhawb nqa tshuab siv los txhawb thiab tiv thaiv daim ntawv piezoelectric ceramic.
3. Lub hauv paus ntsiab lus ua haujlwm. Thaum sab nraud los yog kev ntxhov siab yog siv rau daim ntawv piezoelectric ceramic, nws yuav raug deformation. Vim cov nyhuv piezoelectric, muaj peev xwm sib txawv thiab kev sib cais ntawm tus nqi raug tsim tawm thaum lub sij hawm deformation txheej txheem, uas ua rau tsim cov teeb liab voltage. Cov txheej txheem no tuaj yeem pom raws li cov txheej txheem hloov hluav taws xob, hloov tshuab hluav taws xob rau hauv hluav taws xob hluav taws xob. Tsis tas li ntawd, thaum lub siab thov los yog kev ntxhov siab tau txo qis, daim ntawv piezoelectric ceramic yuav rov qab mus rau nws cov duab qub thiab tsim cov teeb liab rov qab.
