Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a disaster prevention alarm system used mainly in stores, factories, homes, etc.
More specifically, the present invention relates to a rainproof composite emergency warning device. When installed outdoors and exposed to moisture due to rain, snow, or other reasons, the device has a means to prevent moisture from entering through a rainproof membrane to prevent moisture from entering the composite device. .

[Prior art]

What is shown in FIG. 3 is an exploded view of a rainproof mechanism of a conventional rainproof composite device. Rainproof membrane 10 in Fig. 3
As shown in FIG. 2, reference numeral 1 denotes a sounding opening of a resonator 106, which is located between the compound device cover 102 and the mount box 104, and is mounted so that its surface is flush with the mount box 104. It is pasted around part 107. The rainproof membrane 101 attached to the mount box 104 as described above prevents moisture from entering through the open acoustic hole 109 of the rainproof composite device cover 102 due to rain, snow, or other reasons from entering the interior of the composite device. This allows the interior of the composite device 100 to be kept dry at all times. However, in this case, since the rainproof membrane 101 was attached on the mount box 104 as shown in FIG. 2, the rainproof membrane 101 was often damaged when the composite device was attached or removed. .

Mount box 104 is an even bigger problem.
Since the sound generating body 105 fixedly installed inside the sound generating body 105 resonates the sound emitted by the sound generating body 105 and covers the surface of the opening lid 111 which also includes the resonance part 106 which is integrated with the sound generating sound hole 110, the sound generating body 105 and The attached rainproof membrane 10 produces sound with an effective volume by the resonance part 106.
1, the volume was reduced by 4 to 5 dB on average.

[Problem that the invention attempts to solve]

As mentioned above, the louder the rainproof composite device 100 generates due to its original purpose, the better. It prevents troubles such as malfunctions and operation stoppages from occurring by penetrating the inside of the multifunction device 100 and affecting the inside of the multifunction device 100, ensuring reliable operation, and preventing accidental installation and removal. Rain film 101
The rainproof membrane 101 may be damaged due to mischief, etc.
This invention was devised to prevent this from being torn.

[Means to solve the problem]

The rainproof composite device 100 according to the present invention was created by performing various simulations to eliminate the drop in sound volume, and as a result, a sounding body was attached to an open storage section provided in a part of a mount box having an opening lid. The front surface of the sound-producing body is covered with a rainproof membrane, and the sound-producing opening is provided with a sound-producing acoustic hole so that the surface of the rainproof membrane can be kept flat, and the surrounding part of the sound-producing body is fixed to cover the resonating part, Additionally, in order to prevent rainwater from entering between the rainproof membrane and the storage area provided in part of the mount box, the rainproof membrane is held down and fixed from above using a rainproof membrane holding ring.

[Effect]

The present invention is a combination of a sounding body 105 and a resonating section 106 located on the upper part of the sounding body. 10
1, the resonant sound volume is attenuated by the rainproof membrane 101, but when the rainproof membrane 101 is placed in front of the sounding body, the function of the resonant part 106 is not impaired, and it can be prevented from being tampered with. It was also effective in preventing damage to the rain film.

〔Example〕

To explain the present invention in detail with reference to the drawings, the first
The figure is an external view of a rainproof composite device 100 according to the present invention. The external appearance of this drawing is the same as that of a conventional rainproof composite device since only the method of attaching and pasting the internal rainproof membrane 101 is different. FIG. 2 is a perspective view of one embodiment of the rainproof composite device according to the present invention, in which a rainproof composite device cover 102, a rainproof composite device case 103, and a mount box 104 are combined.

As shown in FIG. 3, a conventional rainproof composite device 10
0 means that the rainproof membrane 101 is located above the opening lid 111, and the sounding opening 107 and lower resonance part 1 forming the opening lid 111 as shown in FIG.
The difference from the case where the rainproof membrane 101 is located on the lower edge side of 06 can be clearly recognized.

Referring again to FIG. 2, the rainproof composite device cover 102, the sounding opening 107, and the resonator 10
The opening lid 111 and the rainproof membrane 10 are integrated including 6.
1, a sounding body 105, and a mount box 104 are arranged in this order to constitute a rainproof composite device 100 of the present invention.

The opening lid 111 has a sounding opening 107 and a resonating section 10.
6, align the center of the combined structure with the center of the rainproof membrane 101, and press the rainproof membrane 10.
1 encloses the open lid 111 and the resonator 106, forming a structure such as the sounding body 105 inside the storage section 116 of the mount box 104 as shown in the sectional view shown in FIG.

The tip of the rainproof membrane 101 and the mount box 104
To connect the rainproof membrane 101 to the mount box 104, use adhesive to spread the tip of the rainproof membrane 101 over the mount box 104, and use the rainproof membrane holding ring 108 to attach the edge of the rainproof membrane 101 to the marginal edge on the mount box 104. Glue and press to secure.

The rainproof membrane 101 and the mount box 104 are fixed in the shape of the adhesive part 112 shown in FIG. The sounding body 105 is located in front of the rainproof membrane 101,
The resonator 106 can operate effectively.

Since the rainproof membrane 101 cannot be seen from the composite device cover 102 under normal conditions and is not exposed on the mount box 104, the rainproof membrane 101 will not be damaged by mistake during installation and removal. Rainproof membrane 101 due to mischief etc.
damage can also be prevented.

[Effect of idea]

As is clear from the above explanation, the rainproof composite device of the present invention prevents moisture from entering the interior of the rainproof composite device due to rain, snow, or other causes, unlike conventional rainproof membranes. The blocking effect is the same whether it is applied using the pasting method or the method according to the present invention, but in terms of sound volume, the conventional pasting method has a
A decrease of ~5 dB could not be avoided.

No sound reduction was observed in the rainproof composite device 100 using the method of attaching the rainproof membrane 101 according to the present invention, and furthermore, it was caused by incorrect handling of the rainproof membrane 101 when attaching or removing the rainproof composite device 100. Most damage can now be prevented, and damage caused by mischief has been greatly reduced.
