Abstract
An ultrasonic sensor device includes a sensing unit and a component module disposed in a casing. The sensing unit is configured to generate a sensing signal in response to receipt of an external sound wave. The component module includes a base seat, a circuit unit and a cushioning unit. The base seat has a base board and a lower seat portion under the base board. The base board is formed with a recess. The circuit unit is disposed in the recess, is coupled electrically to the sensing unit for receiving the sensing signal therefrom, and is to be coupled electrically to an external electronic circuit. The cushioning unit is disposed at the base seat, and is proximate to the sensing unit.
