PROBLEM TO BE SOLVED: To reduce a vibration sound generated at a printed board by decreasing the vibration of the board. SOLUTION: A buzzer mounting structure for mounting a buzzer 70 for generating an oscillation sound by the vibration of a vibration plate 72 on the printed board 50 so that a plate 71 is mounted on the board 50 so as to become substantially perpendicular to the board 50. Thus, since the plate 72 is substantially perpendicular to the board 50, the vibration direction of the plate 72 becomes substantially perpendicular to the vertical direction A of the board 50. Accordingly, the vibration of the board 50 can be reduced. Therefore, the vibration sound such as chattering sound generated between a boss 12a or the like of a case 12 brought into contact with the board 50 and the board 50 can be reduced.
