ABSTRACT:
A blind with a music box includes a control element and a music box both of which are received in a receiving room provided in a top beam of the blind. The control element engages with an adjusting rod of a transmitting device mounted in the beam. Music will be played when a control rod drives the control element to adjust the facing angle of the slats of the blind and to switch on the power source by the rotation of the control rod by means of the adjusting rod. In addition, the power source is mainly a solar battery in combination with an auxiliary mercury cell which serves as the power source when the solar battery is exhausting.
