1. A therapeutic ultrasonic device, comprising:
more than one arc ultrasonic transducers that can be assembled,
wherein each of the arc ultrasonic transducers comprises:
a plurality of piezoelectric parts disposed at an inner side of the each arc ultrasonic transducer;
a first protruding part and a first concave part disposed at one end of the each arc ultrasonic transducer; and
a second protruding part and a second concave part disposed at another end of the each arc ultrasonic transducer,
wherein the first protruding part and the first concave part of one arc ultrasonic transducer are coupled to the second concave part and the second protruding part of another of the arc ultrasonic transducer, respectively,
wherein the plurality of piezoelectric parts further comprise a piezoelectric sensing element respectively;
wherein the piezoelectric sensing element embedded in each of the piezoelectric parts are operated to receive an echo signal, each of the piezoelectric parts are configured to calculate a time lag from emission of ultrasonic beams to reflection of the echo signals, allowing for adjustment of a driving phase to concentrate the ultrasonic beams and forming of either a single ultrasonic focal zone or multiple ultrasonic focal zones.
