Abstract
An ultrasonic transducer device that can improve a signal-to-noise ratio includes a vibration reduction layer, an acoustic lens, a transducer module and an interface structure. The transducer module is disposed between the vibration reduction layer and the acoustic lens. The interface structure is disposed on a side of the transducer module adjacent to the vibration reduction layer. The interface structure has a plurality of substructures in a regularly arranged manner. A size difference between any two substructures of the plurality of substructures is lower than a predefined value.
