Ultrasonic Emitters with Quartz Piezoelements of Y-Section

摘要

It was found that a quartz crystal cut along the y-axis and excited by an electric current along that axis yields ultrasonic radiations of about twice the intensity of similar crystals cut and excited along the x-axis. An interpretation of the mechanism of this phenomenon is given. It is calculated that a y-type crystal will radiate at the same frequency as an x-type crystal almost 1.5 times thicker.
