DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waterproof
mounting structure of a waterproof radio wounder or a Konhosika used for hand-held
transmission / reception t, S and the like. The conventional attachment structure of this type is as
shown in FIG. 1, and a flat rubber wheel 1-no 7 ya x 4 tll E is inserted between the blade 12 and
the inner surface of the dovetail 11, and the peripheral edge of the speaker frame 13 is screwed
to several points. There were many things we were doing. The speaker cone is made of plastic
and is waterproof. However, with such a structure, the peripheral edge of the frame of the
speaker is screwed in place5, and the rubber wangja is strongly pressed only on the screw-foot
portion without receiving any fixation on the average, and an excessive force on the speaker
frame However, it has a disadvantage that it is preferable in terms of sound quality, and the
waterproofness lacks certainty. SUMMARY OF THE INVENTION It is an object of the present
invention to provide a waterproof mounting structure for a speaker, which has a reliable
waterproof property without applying an impervious force to a speaker frame, for the purpose of
eliminating the above-mentioned drawbacks. Next, explain the draft plan #! 2. Case 1 having a
jetty 2 on the inner side with an inner scout or slightly inclined 3 as shown in FIG. 3 and FIG. In
the U-shaped cross section, * is made of phosphorus, "4" made of a soft rubber pot provided with
a ridge 5 on the outer peripheral edge, so as to spread l1 ti * / 4 at the outer peripheral edge of
the cast 6 It is a turtle which is held in the case 202 and then provided in the case 1 and pressed
into the nine jetty 2 so that the in-machine inclined surface 3 and the ridge 5 of the ring
periphery are in close contact. The pressing force of the speaker 6 is fixed at several places on
the ring 4 at its peripheral edge, so that no excessive force such as deformation of the speaker

frame 7 is applied, so that the sound quality is not adversely affected. Since the present invention
has the above-described structure, the conventional rubber washer is further pressed against the
speaker fixing screw to exert a pressure-resistant waterproof effect. The pressing force of the
ring peripheral ridge is easy to be uniform, and the adhesion with the inner surface of the jetty is
certain, and the waterproof property is also excellent.
