<p>Vibration energy of the sound generated by a sound production mechanism (2) of a music box (1) playing a music is transmitted to a sheet of paper (14) made of Japanese paper via a holding stand (12) so as to vibrate the sheet of paper (14), thereby producing soft and comfortable sound. Moreover, by adjusting a reception unit (16), it is possible to change the curvature radius of the curvature surface of the sheet of paper (14) and adjust the sound volume.</p> |
