Tam sim no cov neeg hais lus feem ntau yog lub tshuab hluav taws xob uas muaj suab nrov, qhov siab tshaj qhov zaus tsis yooj yim mus txog 20 KHZ, cia's saib lub zog ntawm tus hais lus dynamic, lub suab coil ntawv phaj thawb quab yuam F, F Ft. Fe tuaj yeem decomposed mus rau hauv lub zog ntsug thiab kab rov tav, vim muaj qhov muaj nyob ntawm Ft daim ntawv lub khob hliav qab tsim alternating dabtsi yog khoov txav, thiaj li hais tias daim hlau daim hlau los tsim transverse vibration thiab tsim ib tug sawv yoj, sawv yoj ua rau zaus tus yam ntxwv ntawm lub suab nrov. fluctuate nyob rau hauv lub high zaus band thiab tus yam ntxwv nkhaus tsis zoo ib yam txaus. Txhawm rau kov yeej qhov tsis txaus no, sim txo qhov hnyav ntawm daim ntawv phaj (txo qis inertia, yog li txo qis kev co ntawm sab nraud) thiab ua kom lub zog ntawm daim ntawv phaj (txo qhov khoov ntawm daim ntawv phaj los ntawm FT).
Vim li no, tib neeg tau ua ntau yam kev txhim kho rau daim ntawv phaj ntawm lub suab nrov nrov, xws li siv hlau cymbals los ua daim ntawv phaj, uas tsis yog ib qho nyuaj, tab sis kuj yog lub teeb. Ntxiv nrog rau boron yog qhov nyuaj heev thiab elasticity coefficient, yog cov khoom zoo los ua cov ntawv phaj, thawj zaug ua los ntawm titanium rau hauv 10-20 microns tuab phaj substrate, ces muab cov substrate rau hauv lub tshuab nqus tsev, nyob rau hauv qhov kub ntawm 2500 degrees C. , nrog ib tug muaj zog electron beam bombardment boron, ua rau nws deposition nyob rau hauv titanium substrate nto tom qab evaporation, yog li ua ib tug hais lus yog 36 KHZ sab sauv txwv ntawm lub zaus.
Yog tias koj xav txhim kho qhov kev txwv siab tshaj plaws ntawm lub suab nrov, nws yog qhov tsim nyog los hloov cov qauv. Ib lub suab nrov nrog lub siab zaus ntawm 50 kHz siv cov qauv ribbon, raws li pom hauv daim duab 2. Rau cov hlau nplaum ruaj khov tau muab faib ua ob pawg los tsim cov kab ke sib nqus. Cov zaj duab xis vibration yog ua los ntawm 7-8 micron tuab polymer zaj duab xis, uas yog lub teeb thiab mos. Lub vibration zaj duab xis yog txuas nrog aluminium ribbon suab coil 10 micron tuab. Thaum tam sim no ntws los ntawm lub suab coil, zaj duab xis yuav tsim F+ thiab F- rog nyob ntawm qhov kev taw qhia ntawm qhov tam sim no. Tsis muaj teeb meem transverse quab yuam txhua. Vim yog lub diaphragm' lub teeb loj heev, lub diaphragm txav nrog me ntsis inertia, yog li tus neeg hais lus zaus teb yog qhov zoo.
