When attaching such punching nets 3 to 5, it was done as shown in FIG. 2 (corresponding to the section A-A' in FIG. 1). That is, the front plate 2
A retaining ring 6 made of an elastic material such as rubber or resin and having a cross section as shown in FIG. , holder 8, edge 9,
The peripheral part of the speaker unit 11 consisting of the diaphragm 10 etc. is mounted, and this is fixed to the front plate 2 with screws 12, and then a punching net having a circular front face 3a and a cylindrical mounting part 3b on the outer periphery is used. 3 into the retaining groove 6 of the retaining ring 6.
It is press-fitted along the inner circumferential wall of b.

By the way, in this structure, punching net 3
In order to install the retaining ring 6 along the inner peripheral wall of the retaining groove 6b, the punching net 3 and the retaining groove 6b
The punching net 3 must be in contact with the inner circumferential wall of the punching net 3 over a large area to the extent that a frictional force sufficient to prevent the punching net 3 from falling off is obtained. On the other hand, in consideration of workability when replacing the punching net 3, it is preferable that the contact area between the two be as small as possible. Therefore, in order to satisfy these contradictory conditions,
The mutual dimensions must be determined in such a way that the necessary and sufficient contact area is obtained.

However, even if this is done, if for some reason the tip of the mounting portion 3b of the punching net 3 does not reach the bottom of the retaining groove 6b, the retaining ring 6
The holding force caused by the punching net 3 became smaller than the designed value, and there was a risk that the punching net 3 would fall off.

In FIGS. 4 and 5, the same components as those in FIGS. 2, 3 are given the same numbers. Fifth
The figure is a cross-sectional view of a retaining ring 6 made of an elastic material, in which a convex portion 6c is formed on the inner peripheral side wall near the entrance of the retaining groove 6b.
is provided. FIG. 4 is a cross-sectional view (corresponding to the A-A' section in FIG. 1) of a state in which all the parts are assembled, and when the punching net 3 is press-fitted into the retaining groove 6b of the retaining ring 6 The convex portion 6c of the retaining ring 6 is formed on the inner peripheral wall of the punching net 3.
are in contact with each other, and the punching net 3 is held firmly by its frictional force. In this case, since only the convex portion 6c is in contact with the punching net 3, the end of the punching net 3, that is, the attachment portion 3b reaches the bottom of the holding groove 6b immediately after slightly passing the convex portion 6c. Until this happens, the force required for press-fitting is approximately constant, and the force required to prevent it from falling off is also approximately constant. Therefore, even if there are variations in the amount of press-fit during the press-fit process during assembly work, the holding force is not affected in any way, the trouble of checking the quality of the work is saved, and production can be performed with stable quality. It also reduces costs.

In the above embodiment, the convex portion 6c of the holding groove 6b is provided on the inner circumferential wall, but the effect may be obtained even if the convex portion 6c is provided on the outer circumferential wall and is brought into contact with the punching net 3 on the outer circumferential wall side. It's the same. Furthermore, if it is configured so that both sides of the inner peripheral wall and the outer peripheral wall are in contact with each other at the same time,
Needless to say, even better effects can be obtained.

Structure of the Device As described above, the present invention is such that at least one side of the inner circumferential wall of the retaining groove of the retaining ring made of an elastic material protrudes near its entrance, and this protruding portion is brought into contact with the punching net. Therefore, even if the amount of press-fitting when press-fitting the punching net varies, the holding force will not be affected in any way. Therefore, the process of checking the quality of the work can be omitted, reducing the total assembly time and reducing the number of defects. This has the effect of making it possible to significantly reduce costs since the ratio can also be reduced.
