LMEC-21 Vibrating String Experiment (txoj hlua suab ntsuas)

Lus piav qhia luv luv:

LMEC-21 siv cov hlua hlau thiab oscilloscope los ntsuas qhov sawv nthwv dej thiab kev co ntawm cov hlua tsis sib xws, thiab tuaj yeem nthuav tawm cov kev sim tshiab, qhov ntsuas no xav tau tus kheej npaj oscilloscope.
LMEC-21A yog ib qho pheej yig dua version uas tsis xav tau oscilloscope, Lub hom phiaj ntawm qhov ntsuas yog los teeb tsa cov kev sim suab nrov.Nws tuaj yeem tsis tsuas yog ua qhov kev sim ntawm txoj hlua kev vibration ib txwm nkaus xwb, tab sis kuj tseem nthuav dav mus rau qhov kev sim siv los ntsuas qhov intonation ntawm cov hlua cov twj paj nruag thiab kawm cov ntsiab lus ua haujlwm ntawm cov cuab yeej hlua.

Kev sim loj
1. Kev sib raug zoo ntawm txoj hlua ntev, linear ceev, nro thiab sawv nthwv dej zaus yog kawm;
2. Kev nthuav dav ntawm nthwv dej yog ntsuas thaum txoj hlua vibrates;
3. Kev tshawb nrhiav kev sim: kev sib raug zoo ntawm kev vibration thiab suab;4. Kev tsim kho tshiab thiab kev tshawb nrhiav kev sim: Kev tshawb fawb txog kev siv hluav taws xob hloov pauv kev ua haujlwm ntawm kev sawv yoj vibration system.
