Description

[Detailed Description of the Invention] This invention relates to a waterproof side watch, and particularly relates to a structure for attaching and detaching buttons when press-fit buttons are used.

Conventional button structures using press-fit buttons did not have a structure that allowed the buttons to be freely attached and detached from the outside of the case.

In particular, when a watch that uses an electromagnetic speaker has a plastic gasket attached to the case back and is assembled into the case, the difference in pressure between the inside and outside of the case causes deformation of the sound plate and diaphragm, which impairs speaker performance, especially sound pressure. It had the disadvantage of falling.

In order to eliminate the above-mentioned drawbacks, this invention eliminates the pressure difference between the outside and inside of the case by attaching and detaching the button after assembling the back cover, eliminates deformation of the sound plate and diaphragm, and improves the original speaker performance. The purpose is to ensure that

This will be explained in detail below with reference to FIGS. 1 and 2.

FIG. 1 is a sectional view of the waterproof side of this invention. 1 is the torso. 2 is the case back, and 3 is the case back. 3 is made of plastic.

Attach the back cover patch 3 to the back cover 2.

After that, the former is assembled into the body 1. At this time, the diaphragm 5 and sound emitting plate 6 included in the speaker block 6 are deformed by the height of the back cover gasket 3, as the internal pressure of the case increases during assembly.

FIG. 2 is a sectional view of the button part of the present invention.

The press-fit button 7 made of plastic is provided with a screwdriver groove 7a.

Thereupon, the button 7 is taken out from the case 1 from the outside of the case using the lever principle using the screwdriver 8 and the support portion 1a of the case 1. This eliminates the pressure difference between the inside and outside of the case, and deformation of the sound emitting plate 6 and the diaphragm 5 is eliminated. After that, when the button 7 is assembled into the body 1, the original speaker performance is secured.

As described above, this invention has the effect of providing a screwdriver groove in the button and making it easy to attach and detach, allowing use without impairing the original speaker performance. This design is a button air vent structure that is the decisive factor in the plastic back structure of waterproof watches (the back cover structure shown in Figure 1).
