摘要
An ultrasonic transducer that employs a piezoelectric crystal which is made of lead metaniobate so that it has good sensitivity while also having a low Q. The transducer includes a backing support for one face of the crystal which provides damping of the acoustic energy being generated in the reverse direction. The backing support includes an epoxy resin with heavy metal objects moulded therein.
