DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a waterproof sounder.
Related to a portable radio telephone .

[0002]

2. Description of the Related Art FIG. 4 shows a conventional portable radio telephone of this type. In this conventional example, a housing recess 18 for housing a microphone 17 is formed on the back surface of a microphone rib 14 provided in a housing 13.
A microphone rubber 16 forming a ridge 19 along the outer periphery of the front surface is disposed inside the microphone rubber 1, in which a microphone 17 is housed in a microphone rib 14 with a vinyl sheet 15 interposed therebetween.
6 is pressed in and the microphone 17 is fixed.
(See, for example, Japanese Patent Laid-Open No. 3-1).
No. 12242).

[0003]

In this conventional waterproof structure, the structure is complicated and large.
Also, a vinyl sheet 15 for waterproofing is provided in the microphone rib 14.
The microphone rubber 16 containing the microphone 17 is pushed in between them, and the microphone 17 is fixed, so that it takes time to push the microphone rib 14 into the microphone rib 14, and the vinyl sheet 15 is sandwiched between the microphone rib 14 and the microphone rubber 16, so that vinyl for waterproofing is provided. There was a problem that the seat 15 could not be attached accurately and wrinkled.

[0004] For the purpose of simplification, a structure in which a waterproof sheet is directly attached to the front of the housing is considered.
In this method, since the waterproof sheet cannot be sufficiently swung by being sandwiched between the housings, the acoustic resistance increases, and the method is not suitable for a mounting structure requiring a large sound volume such as a sounder.

[0005] The object is easy to perform also works with a simple structure, yet line the waterproof sounder the sound pressure is not reduced to the present invention
To provide a portable radio telephone .

[0006]

[MEANS FOR SOLVING THE PROBLEMS] The portable radio telephone of the present invention
Comprises a housing (1) having a slit (7) ,
2 rubber rings (3b, 3a) and waterproof sheet (4)
When, a a mobile radio telephone and a sounder (5)
The sounder (5) is a slit (7) in the housing (1).
The first and second pins sandwiching the waterproof sheet (4)
Fixed via waterproofing (3b, 3a) and waterproof
You.

A rib (2) for pressing the first and second rubber rings (3b, 3a) around the sound emission hole (7 ).
Is preferably provided.

[0008]

As described above, according to the present invention, a conventional portable phone for waterproofing a sounder, which is complicated and requires a lot of work, is required.
The wireless telephone is formed with a hole in the center and sufficient thickness.
By pressing the waterproof sheet sandwiched between two close-contact rubber rings between the inner surface of the housing and the sounder and fixing it tightly, a simple structure with good workability, low cost, and sufficient sound pressure can be obtained. There is an effect that can be made.

FIGS. 1A and 1B show a first embodiment of the present invention, in which FIG. 1A is a sectional view, FIG. 1B is a perspective view, and FIG. 2 is an exploded perspective view showing a main structure of the embodiment. .

As shown in FIGS. 1 and 2, in a first embodiment of the present invention, a housing 1 of a portable radio telephone (integrated type) 20a accommodating a sounder 5 as an incoming call display is provided.
A slit 7 as a sound emission hole is formed, while a sounder 5 having a sound hole 9 is mounted on a printed board 6 in the housing 1. Since the sounder 5 is attached to the printed board 6 at the correct position, the rib 2 for pressing the sounder 5 from above is formed by the slit 7 of the housing 1.
Is formed on the inner surface around. Rib 2 and sounder 5
Between them, elastic rubber rings 3a and 3b for adhesion and a waterproof sheet 4 are provided. That is, the two rubber rings 3a and 3b for tight contact sandwiching the waterproof sheet 4
This embodiment is constituted by fixing between the sounder 5 and the rib 2 while pushing it. The waterproof sheet 4 is made of a vinyl sheet.

As described above, in the first embodiment in which the rubber rings 3a and 3b are fixed by the ribs 2, the hole 8 is formed in the center of the two rubber rings 3a and 3b. And two rubber rings for close contact 3
Since a and 3b have a sufficient thickness, the waterproof sheet 4 sandwiched between the two rubber rings 3a and 3b is
Receive the sound generated from the sounder 5 as the amplitude of the air,
It can vibrate freely according to the amplitude of air. Even if the waterproof sheet 4 is a thick film, sufficient amplitude freedom can be obtained, so that sufficient sound pressure can be obtained in the same manner as when the waterproof sheet 4 is a thin film, and it is practical and reduces unnecessary man-hours during construction. can do.

FIGS. 3A and 3B show a second embodiment of the present invention, in which FIG. 3A is a sectional view and FIG. 3B is a perspective view.

In the second embodiment, as shown in FIG. 3, since the battery pack 10 is mounted on the rear part of the housing 11 in the portable radio telephone (foldable type) 20b, the mounting portion of the sounder 5 is provided. Shows an example in which the sounder 5 is mounted not vertically on the printed board 6 but in a narrow mounting space, and the housing 11 has no ribs. It is. The main components of this embodiment, such as the rubber rings 3a and 3b for adhesion and the waterproof sheet 4, are the same as those of the first embodiment shown in FIG.

As shown in FIG. 3, when the sounder 5 is vertically mounted on the printed board 6, the case 11 is complicated by the method of fixing with the ribs as in the first embodiment. The work of storing the data in the 11 also requires a lot of man-hours. Therefore, when the sounder 5 is mounted vertically to the printed board 6, the rubber ring 3 for tight contact with the waterproof sheet 4 directly interposed in the case 11 without ribs.
a, 3b are adhered (mounted), and the waterproof rubber sheet 3 is sandwiched between the housing 11 and the sounder 5 by the close contact rubber rings 3a, 3b.
b is sandwiched and fixed.

As shown in FIG. 3, in the case 11 in which only the slit 7 is formed, a hole 8 is formed in the center inside the case 11, and the rubber ring 3a for tight contact with the waterproof sheet 4 interposed therebetween. , 3b are directly bonded, and the sounder 5 is incorporated.

As in the first embodiment, the waterproof sheet 4 receives the sound generated from the sounder 5 as the amplitude of the air by the holes 8 formed in the close contact rubber rings 3a and 3b having a sufficient thickness. It is possible to vibrate freely according to the amplitude of the air, and a sufficient degree of freedom is obtained even with the thick waterproof sheet 4, and sufficient sound pressure can be obtained as in the case of the thin waterproof sheet 4, practical and construction In this case, unnecessary man-hours can be reduced. The rubber rings 3a and 3b for close contact shown in FIG. 3 can have as much thickness as possible because of the absence of the ribs on the housing 11, so that the degree of freedom in amplitude can be sufficiently obtained.

The second embodiment simplifies the structure that is complicated by forming the ribs, or prevents the rubber ring for contact from shifting when the sounder is pushed into the place where the ribs are formed. It is effective to apply it when necessary countermeasures are required. Further, the present invention may be applied to a structure in which there is no space for forming a rib in a housing.

In the above-described embodiment, a vinyl sheet is used as the waterproof sheet 4. However, the present invention is not limited to this, and another material exhibiting the same function, for example, a nonwoven fabric ( polytetrafluoroethylene ) or the like can be used. May be used.

[0019]

As described above, according to the present invention, the waterproof structure of the conventional sounder, which is complicated and requires a lot of man-hours, is waterproofed by two rubber rings for adhesion having a hole formed in the center and having a sufficient thickness. By pressing the sheet sandwiched between the inner surface of the housing and the sounder to fix it tightly, it is possible to obtain a simple structure with good workability, low cost and sufficient sound pressure. There is.
