BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses, as a speaker, a light emitting portion by an LED (light emitting diode) for displaying a state such as a working state in a small portable device such as a mobile phone or a small radio using an LED lens and a speaker. The present invention relates to a waterproof fixing structure for light emitting portions provided adjacent to each other.

[0002]

2. Description of the Related Art Conventionally, in a small portable device such as a mobile phone or a small wireless device, a light emitting portion by an LED (light emitting diode) for displaying a state such as operating is installed near a speaker so that the operating state can be known. LED and LED when doing
The mounting structure of the lens and the speaker is, for example, as shown in FIG. 4, by mounting the speaker 10 on the small portable device main body 9 and the speaker 10 on the speaker installation part of the small portable device main body 9,
The upper part of 10 is fixed with a metal fitting 7 and fixed by screwing. On the other hand, the LED lens 8 is provided with an LED lens installation hole near the speaker fixing portion in the small portable device body 9 to install the LED lens. It was fixed to the small portable device main body 9 by adhering or welding to the hole.

[0003]

However, according to the above-described conventional fixing method, the LED lens 8 is fixed by adhesion or welding, so that the cost becomes high, and the LED lens may be changed depending on the conditions of adhesion or welding. 8 and the small portable device main body 9 may be incompletely contacted with each other, and in the case of a small portable device which is often used outdoors such as a mobile phone or a small wireless device, the LED lens 8 is used. If the fixed part of No. is not completely adhered, water droplets or the like may get into the inside of the main body of the small mobile device from the above-mentioned insufficient adhesion part.

When assembling a small portable device, the conventional LED lens 8 is attached to the main body 9 of the small portable device.
According to the method of fixing by adhesion or welding, the LED lens 8 and the small portable device body 9 must be provided with a wide margin for adhesion or welding by a stepped portion or a protruding portion in order to enhance the fixing force. Therefore, for example, as shown in FIG. 5, it is necessary to provide a wide gap between the speaker and the LED lens for the above-mentioned bonding margin or welding margin, and it is necessary for the above-mentioned adhesion margin or welding margin in the small portable device body. Dimension K
In order to further reduce the size of the main body of the small portable device, there is a restriction on the installation position of the LED lens, and there is a limit to the size that can be downsized.

Further, since the LED lens 8 is directly adhered or welded to the small portable device body 9, the LED lens 8 is assembled at the time of positioning the LED lens 8 and stacking the LED lens 8 so that the adhered portion and the welded portion are not displaced. Work accuracy was also required, and it took time to assemble.

The present invention has been made in view of the above-mentioned problems of the prior art, and is an LE with a metal fitting for fixing the speaker.
The D lens can be fixed at the same time to reduce the space and further reduce the size, and at the same time, prevent the adhesion failure in the fixed portion of the LED lens to improve the waterproof performance.
Further, it is another object of the present invention to provide a waterproof fixing structure for a light emitting portion of a small portable device, which can reduce the number of assembling steps and the positioning labor at the time of assembling.

[0007]

In order to achieve the above object, the present invention provides an LED light guide hole in a speaker holding metal fitting, and an LED lens mounting hole in a body of a small portable device corresponding to the light guide hole. Is provided, the LED lens is fitted and fixed, and the LED lens is pressed against the body of the small portable device by the speaker holding metal fitting. The waterproof fixing structure of the light emitting part of the small portable equipment is characterized by the LED holding lens and the speaker holding metal fitting. Both are fixed and LE
The D-lens fixing space is reduced, and the LED lens and the small portable device body are closely attached to each other to improve waterproofness.

According to a second aspect of the present invention, in the waterproof fixing structure for the light emitting portion of the small portable device, the LED lens is made of rubber.

[0009]

Therefore, according to the waterproof fixing structure of the light emitting portion of the small portable device of the present invention, since the LED light guide hole is provided in the speaker holding metal fitting, the LED can be installed in the space of the speaker holding metal fitting. , The speaker and the LED can be arranged adjacent to each other.

In addition, since the LED lens mounting hole is provided in the small portable device body corresponding to the light guide hole, the LED lens is fitted and fixed, and the LED lens is pressed against the small portable device body by the speaker holding metal fitting. By pressing and fixing the lens to the body of the small portable device, the work of adhesion and welding is eliminated, and the number of processing steps is reduced. Furthermore, by pressing the LED lens on the body of the small portable device with the speaker holding metal, The small portable device main body comes into close contact with each other, and the rattling of the LED lens and the gap between the small portable device main body and the small portable device main body are eliminated to improve the waterproof property.

According to the second aspect of the present invention, since the LED lens is made of rubber, it is elastically brought into close contact with the main body of the small portable device by being pressed by the speaker holding metal fitting, thereby completely preventing the occurrence of a gap. It is what is done.
