DESCRIPTION JPS5148043
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side cross-sectional view of a conventional
diaphragm made of natural or synthetic fibers and having a homogeneous structure, and FIG. 2 is
a partially dense / dense structure using the alumina fiber of the present invention. A side
sectional view of the diaphragm, FIG. 3, FIG. 4, FIG. 5 and FIG. 6 are plan views showing an
arrangement example of alumina fibers in the present invention, and FIG. 1 is a speaker using the
diaphragm according to the present invention It is a frequency-response curve figure of the
speaker which used and the conventional diaphragm. Reference numeral 1 denotes a diaphragm
edge portion, 2 a diaphragm cone portion, 2a a natural or synthetic fiber layer, 2b an alumina
fiber layer, and 3 a diaphragm neck portion. Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 107-real open 5l48043 (2) Fig. 5 Fig. 6 Fig. 7-
[Detailed description of the invention] Honmizo Dormitory has high lyophilic habit and
mechanical loss is thick Alumina fine-fine-grained aluminum oxide (11, o) is formed, and contains
a part of silicon dioxide (810s) The ceramic fiber-which is used for the convenience of the
speaker 4i IFI board for the convenience of the speaker 〇 Among the requirements of the
person as a speaker, it is also possible to make the JI wave number-response characteristics flat.
In particular, it is thought that the sound fii should be a good condition (a power, a power, a
power, a necessary condition, etc.) to carry out the co-image of the co-image generated by the
dividing machine 1 of the frequency of the MK area 7 frequency band 1 plate of the bird area.

adjusted according to the required properties, and it can be easily arranged in the direction of
