<p>An ultrasonic sensor device includes a housing (3), a transducer (4), a securing unit (5) and a circuit board (6). The housing (3) has an enclosingportion (31) formed with first and second openings (311, 312) . The transducer (4) is mounted to the enclosing portion (31) at the second opening (312), and includes an electrically conductive surrounding wall (42) and a piezoelectric member (43) . The securing unit (5) includes a securing component (51) that secures the transducer (4) on the enclosing portion (31), and a connecting pin set including two pins (53, 54) each having an end (532, 542) connected electrically to a respective one of the surrounding wall (42) and the piezoelectric member (43). The circuit board (6) is disposed at the first opening (311) of the enclosing portion (31) for electrical connection with the connecting pin set.</p> |
