Description

[Detailed description of the invention] The present invention relates to a portable waterproof watch with an audio device, and provides a portable waterproof watch with an audio device that is easy to process, has excellent water resistance, and allows easy replacement and installation of speaker covers. The purpose is to

The button on the waterproof watch that has a built-in sound device has a sound emitting hole in the body to transmit the sound emitted from the diaphragm of the sound device to the outside. A dustproof sheet with fine holes is installed to prevent entry and emit sound.

In addition, a speaker cover is provided to visually hide the dustproof sheet and to express the design feature of the built-in audio system.

However, in order to commercialize this as a waterproof product, it was desired to develop a fixing method with excellent water resistance, and to make it possible to easily replace the dustproof sheet section, which is prone to dust particles.

The structure of a conventional soundproof section is as shown in Fig. 1, in which a dustproof sheet 2 is glued above the sound emitting hole 1a of the body 1, and the design is designed to protect the dustproof sheet 2 and include a sound device. I glued speaker cover 3 to express it.

4 is a sound device, 4a is a diaphragm, 5 is a packing, 6
is a fixed ring with a sound device soldered to the body.

This conventional structure of the speaker cover has the disadvantage that it is not water resistant because it is fixed by adhesive, and the adhesive deteriorates when the button is pressed for a long time.

Further, since the speaker cover 3 is exposed on the upper surface, it is difficult to fix the speaker cover 3 by caulking, welding, or the like.

Further, the dustproof sheet 2 has a fine mesh and easily attracts dust, but it is difficult to replace it because it is fixed using adhesive for its appearance.

The present invention aims to eliminate the above-mentioned drawbacks, provide a structure with stable water resistance, easy replacement of dustproof parts, and an excellent appearance.

One embodiment will be described with reference to a side sectional view in FIG. 2, speaker cover frame drawings in FIGS. 3, 4, and 5, and a plan view of the speaker cover in FIG. 6.

As shown in the plan view of the speaker cover frame in FIG. 3, the sectional view of the speaker cover frame in FIG. 4, and the sectional view of the speaker cover frame slit in FIG. 5, it is made of plastic.

A slit groove 10a is provided on the side surface of the speaker cover frame 10, and a protrusion 10b is provided on the lower part.

Furthermore, a sound emitting dustproof hole 10c is provided which plays the role of a conventional dustproof sheet.

As shown in FIG. 6, a projection 13a that engages with a slit groove 10a of a speaker cover frame 10 is provided on the outer periphery of a speaker cover 13 made of metal and whose surface has been subjected to finishing treatments such as patterning and plating.

13c is a sound emitting hole, and 13d is a pseudo sound emitting hole in design.

As shown in the side sectional view of FIG. 2, the protrusion 13a of the speaker cover is inserted into the slit groove 10a by pushing out the side wall of the speaker cover frame 10, and the protrusion 10b of the speaker cover frame 10 is inserted into the engagement groove 11b of the body 11. It has a structure in which the biting is fixed by the interference having in the radial direction.

The speaker cover frame 10 and the body 11 are fixed by the protrusion 10b.
, 10b can be fitted into the engagement groove 11b of the body 11, so there is no need for the speaker cover frame 10 to have a tightening margin between the outer periphery of the speaker cover 13 and the body 11, but both ends of the speaker cover 10 It is effective to provide a portion of the speaker cover frame 10 with an interference margin in order to prevent the speaker cover frame 10 from lifting up.

11c is a sound emitting hole in the body, 14 is a sound device, 14a is a diaphragm watertightly fixed by welding or the like, 15 is a gasket, and 16 is a sound device fixing ring brazed to the body 11.

FIG. 7 shows the speaker cover 23 attached to the speaker cover frame 20.
This figure shows an embodiment of the present invention that is attached by heat caulking.

A thermally caulked portion of the speaker cover frame 20 that fixes the speaker cover 23 is indicated by 20b.

The speaker cover frame 20 is attached to the body 21 by biting the protrusions 20a as shown in FIG.

In this case, the tip 20a may be formed by thermal deformation (a method similar to normal thermal caulking) as a method of forming the protrusion 20a.

By appropriately adjusting the amount of protrusion of this protrusion 20a, the body 2
It is possible to bite into 1.

Another embodiment is shown in FIG. 8, in which the speaker cover 33
A dustproof sheet 32 may be provided between the speaker cover frame 30 and the speaker cover frame 30 and attached to the body cover.

As described above, since the present invention has a non-adhesive structure, it is completely water resistant and can be made into a waterproof watch.

In addition, the speaker cover and speaker cover frame can be easily replaced by simply pushing them from the body sound emitting hole to remove the mechanical bite, and there is no need to remove the adhesive.

Furthermore, it is easy to install, simply by pressing the speaker cover frame from above and mechanically attaching it, and there is no need to apply adhesive or dry it, reducing costs in the assembly process.

The speaker cover frame can also serve as a dustproof sheet, and the speaker part has an excellent waterproof structure that can be mass-produced at low cost using plastic.
