ELECTROMAGNETIC ULTRASONIC TRANSDUCER AND ARRAY THEREOF

摘要

An electromagnetic ultrasonic transducer and an array thereof are provide s. The electromagnetic ultrasonic transducer includes a support (8), an elas tic board (6) disposed on the support (8), a magnetizer (7) on the elastic b oard (6), and a magnet field generator (1) for vibrating the magnetizer (7), wherein the thickness of the magnetizer (7) is of the order of microns. The thickness of the elastic board (6) is also of the order of microns. The ele ctromagnetic ultrasonic transducer is able to produce acoustic waves of high frequency, which are useful for ultrasonic treatment.
