addition, it is an object of the present invention to provide a mounting of the diaphragm
protection cover which does not get knocked during the operation of the speaker. An
embodiment of the present invention will be described with reference to the drawings. 1 is a
frame and one frame, 2 is a diaphragm, 3 is a resiliently flexible fixed patch with some elastic
force such as a rubber having a cross section formed in a letter shape, 4 is 111aK "of them. 4;
−47-201i, + 2-09 · a diaphragm device cover to be in pressure contact with the panel 3; 5Fi
speaker frame l and a rubber formed in the narrow groove formed in the diaphragm holding
cover 4 and being in pressure contact with each It is an O-ring with some resiliency or flexibility.
In order to attach the diaphragm retaining cover 4 to the speaker, the diaphragm protecting
cover 4 may be inserted into the pad 3 and the IIK O-ring 5 corresponding to the pad 3 from the
outside of the retaining cover 40 may be fitted. It is. As a result, the work cover 4 is determined
as in No. 7E by the elastic force due to the deformation of the O-ring 7 patkin. IIP, 3 physicians,
49 is another embodiment, the implementation of FIG. 3 is to attach flanges to the protective
cover 4 to hold the construction cover 4 more securely and to remove the construction cover 4 It
is also 2] that it was made to withdraw O ring 5 simultaneously. The embodiment of FIG. 4 shows
that the Kk-L O-ring 5 only needs to be in contact with the speaker frame 1 and the working
cover 4 when holding the working cover 4 shown in FIG. In the above description, O-ring is used
to explain 9-2-47 "2 ratio 2-10, but it is not necessary to be O-ring in the case of Fig. 3 or the
like. . In addition, the cross section of the packing is formed in a single-letter shape to generate a

flicker, and K <composition is not limited to this shape. The diaphragm protection cover
mounting device of the present invention as described above can be sufficiently different from
the above-described object, and is truly useful in practice.
