| 摘要 |
The present invention relates to a metallic vibration plate for a music box which is placed on the outer circumferential surface of a cylindrical drum (1) comprising a plurality of protrusions (2) on the outer circumferential surface thereof and collides with the protrusions (2) to generate sound by the vibration thereof.The vibration plate (10) comprises: a plurality of vibration pieces (20) comprising a plurality of sound generation pins (21) having different lengths which collide with the protrusions (2) of the cylindrical drum (1) to generate sound by the vibration thereof, and plate-shaped fixing portions (22) protruded in the thickness direction of the sound generation pins (21) and provided at a base portion of the sound generation pins (21); spacers (30) which are inserted between the vibration pieces (20) and are in contact with the fixing portions (22) to space the vibration pieces (20); and a fixing member for integrally fixing the fixing portions (22) of the vibration pieces (20) and the spacers (30). |
