BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing the ?structure? of a
conventional honeycomb diaphragm for a speaker, and FIG. FIG. 3 shows the structure of the
honeycomb diaphragm for a speaker according to the present invention. '3 is a thin film, 1 is a
honeycomb structure, and 2a and 2b are skin materials.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a four-speaker
vicinal diaphragm made by sticking 7 plates on both front and back sides of a honeycomb
structure. As shown in FIG. 1, the conventional honeycomb diaphragm for a speaker has a
structure in which skin materials (2a) and (2b) are adhered to both the front and back sides of
the honeycomb structure (1). Then, as shown in FIG. 2, in the honeycomb structure (1), thin films
(3) such as aluminum are adhered at predetermined positions P and sequentially laminated, as
shown in FIG. In the direction of the arrow in Fig. 1) и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и и
и и и и и и и и и . The present invention is an improvement of such a conventional defect, and it will be
described with reference to FIG. 3 that the extension direction (arrow a in the figure) of the nonone cam structure (1) and the machine of the skin materials (2a) and (2b) It has a structure in
which it is made to coincide with the large strength river (figure arrow b). That is, the skin
materials (2a) and (2b) are made of, for example, a polymer stretched film, paper made of paper,
etc., the former has high mechanical strength and degree such as bending rigidity and tensile
strength in the direction of stretching, and the latter is The mechanical strength of the
papermaking direction, that is, the orientation of the fibers is large, but in view of such points,
the present invention is directed to the direction of increasing the mechanical strength of the
skin materials (2a) and (2b). It is the structure which made the extending | stretching direction of
a structure (1) correspond. In the three or more structures, the direction in which the bending
rigidity of the honeycomb structure (1) is small matches the direction in which the skin materials
(2a) and (2b) increase the mechanical strength, and the honeycomb structure (1) (2a) and (2b),
the rigidity of the diaphragm as a whole is not only significantly increased, but also has excellent
mechanical properties (especially bending rigidity). ) Is reduced. Accordingly, the divided
vibration mode becomes difficult to be applied, and the divided vibration frequency is not high,
and the piston vibration reconnaissance region is expanded, so that a wide frequency range-V
carrier frequency characteristic can be obtained and distortion Has the advantage of obtaining
good quality reproduced sound.
