Title:
DIAPHRAGM DEVICE OF MUSIC BOX
Document Type and Number:
Japanese Patent JP2542544
Kind Code:
B2
Abstract:
PURPOSE: To decrease the interval of pins generating the same sound by providing a projection at the intermediate part of a vibrating piece and flipping the projection with a pin implanted in a rotary drum or a rotary disk.
CONSTITUTION: Pins 11 and 12 are implanted in the rotary disk 10 and flip the same vibrating piece 16. A pedestal 13 has the diaphragm 14 fixed with a fixing screw 15. The vibrating piece 16 constituting the diaphragm 14 has its flank bent by being bent from its intermediate part to the side where it does not come into contact with the rotary drum 10, and the projection 16a is provided at the bent part from the closest position to the rotary drum 10. Thus, the projection 16a provided at the intermediate part of the vibrating piece 16 and the projection from the bent part of the vibrating piece 16 are flipped with the pins 11 and 12 implanted in the rotary drum 10 or rotary disk, so even when the vibration width of the tip of the vibrating piece 16 is not varied, the vibration width of the part of the projection 16a at the intermediate part is greatly decreased, and consequently an implantation interval for a next pin for flipping the same vibrating piece 16 is greatly reduced.
