| Abstract: | The measurement of sound velocity is a commonly comprehensive experiment among university physics experiments.Our design idea is to,based on the original equipment,improve the signal source and make acoustic levitation parts so as to measure sound velocity in different ways;and demonstrate the experimental phenomena of acoustic levitation.The sound velocity measurement experiment instrument has strong levitation stability,accurate sound velocity measurement,low cost and convenient applications.This design saves laboratory resources and space. |
