Music box diaphragm and its production manner

摘要

In the music box diaphragm of the metal material where sound is generated by the vibration with the fact that this invention is laid out in the peripheral surface of the cylindrical drum and 1 where the projection 2 multiple is extended to peripheral surface strikes with aforementioned projection 2, as for aforementioned diaphragm 10, multiple vibrating bars 20 which consist of the tabular conclusion base 22 which is extended to the thickness direction of acoustic generation pin 21 multiple acoustic generation pins making provision for the basic destal of 21 of the length which differs mutually sound is generated by the vibration with striking with the projection 2 of aforementioned cylindrical drum 1 and the said acoustic generation pin 21; Being interposed between the said vibrating bars, 20 touching with the aforementioned conclusion base 22, the spacer 30 which makes each vibrating bar retire 20 mutually; And the conclusion base it is the music box diaphragm which includes the conclusion component which locks 22 of aforementioned vibrating bar 20 and spacer 30 as one unit.
