    摘要: A quasi-self focusing high intensity and large power ultrasonic transducer. It includes a backing and piezoelectric crystal sheets. The backing has double layer structure and there is an air cavity between the layers. At least four piezoelectric crystal sheets are adhered tightly on the inside focusing face of the backing. A protective layer is covered on the surface of the sheets.
