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.

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.

An ultrasonic sensor includes a casing body and a piezoelectric element. The casing body has a base wall and a surrounding wall that cooperates with the base wall to define an interior space. The base wall has a top surface and a bottom surface. The top surface has a first section, a second section that extends between the first section and the surrounding wall, and a connecting section interconnecting the first and second sections. A distance between the second section and the bottom surface is larger than that between the first section and the bottom surface such that the connecting section and the first section cooperate to define a recess. The piezoelectric element is confined in the recess.

A sticker package includes a sticker assembly and a package case. The sticker assembly includes an elongate strip of flexible film and a continuously extended sticker attached to a surface of the flexible film. The sticker has a projection area on the surface of the flexible film that is smaller than the surface area of the surface of the flexible film. The package case includes upper and lower lids. The upper lid is bulged to form a receiving compartment. The lower lid is cut to form an opening. The sticker assembly is wound up as a roll received and retained in the receiving compartment with a leading end extending out of the case through the opening. To use, the sticker assembly is pulled off the package case through the opening and the sticker is then allowed to peel off the flexible film.

A transfer-printing sticker includes a release paper, a transparent base paper, and first and second sticking members carrying different patterns with the patterns arranged between the base paper and the release paper. The first sticking member contains a first pattern that is arranged to contain hollow portions. The second sticking member contains a second pattern that is arranged in accordance with the hollow portions of the first pattern. To use the transfer-printing sticker, the release paper is removed and the base paper is stuck to an article or a piece of paper and with slightly pressurization, the patterns are transferred. The arrangements of the first and second patterns allow for formation of different transfer printing effects. The second pattern can be set in the hollow portions of the first pattern and thus both can be formed with the same piece of sticker paper.
