<p>A music box 10 comprising a blower unit 15 and a flute unit 23. Each flute 23a in the flute unit 23 includes a mouth 28a and a wind inlet hole 133a for feeding air to the mouth 28a and the wind inlet holes 133a for feeding air to the flute are selectively opened and closed to produce a desired melody. Further, an air outflow hole 55 is provided in a wind trunk 31 of the blower unit 15 and a disk 42 having holes for cyclically opening/closing the hole 55 is rotatably provided. Thus the pressure of wind fed to each flute changes at a predetermined frequency. As a member for recording a melody, the following two methods are available. One method is a disk 21 having protrusions 22 for pressing key members 66e of the flute unit and another method is a perforated web 210 which opens and closes the air inlet hole 133a of the flute unit. <IMAGE></p> |
