| titleOfInvention | Ultrasonic transducer |
| abstract | (57) [Summary] An ultrasonic transducer that forms a substantially annular array by arranging a frame-shaped ultrasonic vibrator composed of vibrator pieces having a rectangular cross section around a core ultrasonic vibrator. By forming the ultrasonic vibrator unit, the ultrasonic vibrator constituting the ultrasonic vibrator unit has no curved surface and is formed in a simple shape of a prism, so that it can be easily manufactured by a piezoelectric material having good transmission characteristics. . SOLUTION: An ultrasonic transducer unit 30 constituting the ultrasonic transducer 6 has a substantially rectangular overall shape, and a rectangular core ultrasonic transducer 33 is disposed at the center thereof. A first frame-shaped ultrasonic transducer 34 is arranged so as to surround the first frame-shaped ultrasonic transducer 34, and a second frame-shaped ultrasonic transducer 35 is arranged to surround the first frame-shaped ultrasonic transducer 34. Is provided. Each of the frame-shaped ultrasonic vibrators 34 and 35 is composed of four vibrator pieces each having a substantially quadrangular prism shape, and the surface side electrodes of the vibrator pieces constituting the same frame-shaped ultrasonic vibrator are made of a conductive material. At 40, they are electrically connected. |
