あつた。 Conventionally, as shown in FIG. 1, there is a speaker diaphragm in which a diaphragm portion a and an edge portion b are integrally formed of the same material. However, this type of speaker diaphragm has the disadvantage that when a highly elastic material (beryllium, boron, etc.) is selected as the material, the lowest resonance frequency increases and the low frequency reproduction limit increases. Therefore, as shown in Fig. 2, when the diaphragm part a is made of a high elastic material, the edge part b is made of a low elastic material such as cloth or plastic, and the two are bonded together with an adhesive c. There is. However, in the diaphragm shown in FIG. 2, the work efficiency in the manufacturing process was poor, the dimensional accuracy between the two was not improved well, and there was a limit to the adhesive strength.

かあるいはそのまま使用するのが通常である。 Hereinafter, one embodiment of a dome-shaped diaphragm will be described with reference to FIG. 3 and subsequent figures. When performing evaporation or sputtering of highly elastic materials such as beryllium or boron, the required substrate is formed of aluminum, titanium, copper, or phosphor bronze, the evaporation or sputtering is performed on this, and then the substrate is removed or left as is. Usually used.

する。 In this embodiment, as shown in FIG. 3, the edge portions of the substrate 1 made of the above-mentioned material, which have the shapes of the diaphragm portion a and the edge portion b, are used as the edges as they are. Then, the edge portion b is masked with a highly heat-resistant ring-shaped member 2, leaving only the inner peripheral end.

る。 From the above, the diaphragm part a is made of a highly elastic material such as beryllium or boron, and the edge part b is made of a relatively low elastic material such as aluminum, titanium, copper, or phosphor bronze. . Therefore, the diaphragm part is made of a highly elastic material so that the frequency at which split vibration starts can be increased, and the edge part is made of a relatively low elastic material to realize a minimum resonant frequency that is sufficiently low as a speaker. You will be able to do this. Therefore, faithful reproduction can be performed over a wide frequency band.

Further, the highly elastic material may be attached by a physical base growth method or a chemical base growth method other than those described above, or even by coating.

はホーンスピーカ等の振動板に最適である。 As described above, according to the present invention, a good diaphragm can be obtained because the diaphragm part and the edge part, which are made of different materials, take advantage of their respective functions, and the edges do not require adhesion or special formation. Dimensional accuracy does not deteriorate due to variations in the thickness of the agent. The present invention is most suitable for diaphragms such as horn speakers.
