Acoustic load dependency of electroacoustic efficiency in the electrostrictive ultrasonic transducer and acoustical matching
H. Banno,Y. Masamura,N. Naruse +2 more
TL;DR: In this article, the acoustic load dependency of the electroacoustic efficiency in the electrostrictive transducer is derived theoretically and measured experimentally, and the results show that there is an optimum acoustic load resistance which maximizes the electroACoustic efficiency.
