Abstract

An apparatus of the disclosure is directed to conical structure of an ultrasonic transducer. The conical structure may have a first circumference and a second circumference, respectively located at opposite ends of the conical structure, where the first circumference has a greater length than the second circumference. An angle may be formed between a plane including the second circumference and a surface of the conical structure, and a distance may be formed between the first and second circumferences. A rim may be coupled at or adjacent to the first circumference of the conical structure. An ultrasonic transducer may be coupled to the second circumference of the conical structure.
