Abstract
An ultrasonic sensor device includes a housing, a circuit board disposed at the housing, and a transducer. The transducer includes an electrically conductive casing having a bottom wall and a surrounding wall. A piezoelectric member is disposed on top of the bottom wall. A first connecting pin set is disposed in the housing, and includes a first connecting pin having one end connected to the circuit board and another end connected to the piezoelectric member, and a second connecting pin having one end connected to the circuit board and another end connected to the surrounding wall. A second connecting pin set is disposed in the housing, has one end connected to the circuit board, and another end extended into a connecting portion of the housing.
