The Cymbal transducer consists of an inner piezoelectric disk mechanically coupled to two thin metal endcaps on each of its faces by an epoxy. This miniature flextensional transducer is an emerging technology that has been used principally in underwater applications for large area and restricted volume transmit and receive arrays. This paper is focused on the use of this transducer in power ultrasonics applications. Based on previous studies of ceramic and metal cymbal configurations, a new improved model has been analyzed to evaluate the differences and advantages against the traditional cymbal. For this purpose, a theoretical electro-mechanical analysis and finite element analysis (FEA) have been realized. The aim of this work is to develop a new double ceramic half-cymbal prototype for high power ultrasonic cutting applications.
