Cov ncauj lus kom ntxaws tshuaj ntawm cov txheej txheem hloov dua siab tshiab los ntawm lub suab cim teeb liab rau hluav taws xob teeb liab
Unveiling How Sound Becomes Electrical Signals: Three Key Technologies-Electromagnetic Induction, Capacitive, and Piezoelectric-Demonstrate Unique Strengths. Cov ntsiab cai sib txawv phim sib txawv sib txawv nrog cov xwm txheej tshaj lij rau cov teb tshwj xeeb.
1. Cov hau kev ntawm hloov cov suab rau hluav taws xob
1.1 ◆ INTEROMAGNESS INFUNDING CONTER
Neeg kho tshuab deeg tshwm sim los ntawm cov suab tsim kev hloov pauv hauv daim teb sib nqus hauv cov khoom sib nqus hauv cov khoom siv hluav taws xob hauv hluav taws xob, yog li tsim hluav taws xob. Txoj kev hloov pauv hloov no muaj ntau nyob rau thaum ntxov micro irophones. Nws lub ntsiab cai yog ua rawsFaraday Txoj Cai ntawm Electromagnetic Induction: Sound-induced mechanical vibrations alter the magnetic field, producing an electrical current.
Qhov no zoo ib yam li tus hais lus ua haujlwm.
1.2 ◆ hloov siab hloov siab hloov siab
Suab nthwv cua ua rau cov sib txawv hauv catchalitics daim phiaj, uas yog li hloov dua siab tshiab rau hauv voltage lossis cov cim tam sim no.
Lub suab deeg hloov qhov deb ntawm capacitor daim phiaj, ua rau kev hloov pauv hauv capitalitance. Qhov sib txawv no hloov mus rau hauv voltage lossis cov teeb liab tam sim no nyob rau hauv Circuital, ua tiav suab {{1} {qhov hluav taws xob hloov dua siab tshiab.Peev xwm Microphonestau siv dav hauv cov kws tshaj lij kev paub vim lawvHigh rhiab heev thiab tsawg lub suab yam ntxwv.
1.3 ◆ Piezoelectric Conversion
Piezoelectric cov ntaub ntawv tsim cov hluav taws xob thaum raug rau kev ntxhov siab ntawm cov neeg kho tshuab, ua kom cov cim hluav taws xob suab.
Txhua yam kev ntxhov siab ntawm lub suab ua rau cov ntaub ntawv piezoelecric los tsim voltage. Piezoelectric hloov dua tshiabCov lus teb ceev thiab yooj yim, ua rau nws dav siv tau hauv cov cuab yeej siv thiab sensors.
