    摘要: In a rolling process, the level of rolling performed by a rolling mill for one operation is set to 1 μm to 20 μm. A magnesium substrate is rolled by rollers while being heated by a thermostatic chamber. As a result, there is manufactured a high-quality magnesium sheet which is less susceptible to influence of oxidation, which realizes a high internal loss, prevention of a drop in sensitivity, and low distortion, and which has a thickness of 30 μm to 100 μm. Further, as a result of the magnesium sheet being formed into a semi-dome shape or a dome shape, the sheet can be inexpensively manufactured as a speaker for high-tone playback. In particular, in the case of a magnesium diaphragm into which a dome section and an edge section are integrally formed, high-quality sound can be played back in a high frequency range without involvement of a drop in sensitivity.

    摘要: In the rolling process, a rolling amount at each time of rolling by a rolling machine is set to 1 μm to 20 μm, and a magnesium substrate is heated by a constant temperature oven and rolled by rollers. Thus, a magnesium sheet of 30 μm to 100 μm is produced. This magnesium sheet is used to form a bobbin and a diaphragm integrally molded with each other, and the diaphragm is molded into a semi-dome shape or a dome shape. Thus, a bobbin integrated type magnesium diaphragm having the semi-dome shaped diaphragm or the dome shaped diagram is manufactured. The bobbin integrated type magnesium diaphragm is applied to a dynamic speaker device. As a result, the high-quality dynamic speaker device, which realizes high rigidity, high sensibility, high internal loss, less distortion and the like, is obtained.
