BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view showing a conventional
diaphragm, and FIG. 3 is a sectional view showing a diaphragm according to an embodiment of
the present invention. 1 ииииии Metal diaphragm, 2 ииииии Rubber damping material, 3 иииии Damping
paint, 4 иии Glass fiber cloth diaphragm with metal bound. In the drawings, the same reference
numerals denote the same or corresponding parts.
DETAILED DESCRIPTION OF THE INVENTION This invention relates to the improvement of
loudspeaker diaphragms using metal. Conventionally, diaphragms using metal have been shown
in FIG. 1 and FIG. The metal was mainly a single plate, and those for damping were added. In
FIGS. 1 and 2, (1) is a metal diaphragm, (2) is a rubber-based material, and (2) is a damping paint.
Among them, the diaphragm using metal has high speed of vibration propagation speed
compared to other materials, and by making it into a thin film, the multiple amount can be one
degree unchanged, which is particularly advantageous for high-pitched sound there were.
However, due to the inherent noise of the metal, it must be dumped to counteract the word f / g
There was a defect that the sticking with the agent was peeled off. The present invention is
intended to eliminate the above-mentioned drawbacks, and it is an object of the present invention
to provide a diaphragm capable of striking an inherent sound from a person who has an
advantage point of metal. Hereinafter, an embodiment of the present invention will be described
with reference to the drawings. In FIG. 3, (6) is formed by integrally binding a metal such as the
surface Ku (aluminum), Ti (titanium), B (ha), B @ (beryllium), etc. of a cloth woven with glass fiber
yarn. It is a vibrating diaphragm. As a result, the vibration propagation speed propagates through
the surface metal, without being inferior to conventional metal veneers, and the sound inherent
to the metal is dumped in the woven fiberglass cloth. As described above, according to this
invention, since special damping is not required as in the prior art, it is expected that N, (powder
?; simplification of machining).
