Ultrasonic probe

The utility model discloses an ultrasonic probe which consists of a probe main body and a convex curved surface piezoelectric wafer arranged at the front end of the probe main body. The ultrasonic probe disclosed by the utility model adopts the convex curved surface piezoelectric wafer with curvatures, different curvatures can be made according to demands, the range of an acoustic beam divergence angle is widened, the acoustic beam divergence angle can be within a range of 0 to 90 degrees or a larger range, and moreover, as a whole piece of wafer with large size, the divergence angle is increased, and the energy of an acoustic beam is uniformly distributed in different directions, and the energy of the acoustic beam and the signal to noise ratio in detection are improved.
