Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a warning sound device, and in particular to a warning sound device that is most suitable for installation on ships and the like where severe spatial restrictions are imposed upon installation. .

[Prior art and its problems]

Conventional alarm devices include, for example, electromagnetic relays.
The so-called bell type is well known, in which a hammer is vibrated by turning on and off to strike a nearby bell.

In this bell-type alarm device, the alarm generating section is composed of the hammer and a bell attached near the hammer, so the entire device including the alarm generating section and other electromagnetic relay sections can be made small. Because of this, it has been widely adopted on ships and other vessels where severe spatial restrictions are imposed on the installation location. However, the alarm system with this configuration vibrates the hammer by turning on and off an electromagnetic relay. The major drawback is that the hammer is severely damaged, and the spark that inevitably occurs when the electromagnetic relay turns on and off can have negative effects on other electronic devices.

Therefore, as an alarm device that eliminates the disadvantages of the bell-type alarm device, an alarm device that uses electronic sounds has been developed. Although the electronic sound generation circuit itself is extremely small and compact because it uses a speaker, the horn-shaped speaker protrudes forward and occupies a wide space, so it is difficult to connect bridges, passageways, engines, etc. If it is installed in a narrow space such as a room, the protruding horn-shaped speaker becomes a nuisance in the event of an emergency situation, which is extremely dangerous.

[Means for solving problems]

The present invention has been made in view of the above-mentioned problems, and includes a first circumferential wall portion located on the inner side and a second circumferential wall portion located on the outer side, which are connected to each other at the bottom, and the first circumferential wall portion A lid having a cylindrical body having a plurality of protrusions on a top surface extending from the cylindrical body, and a first circumferential wall portion located on the inside and a second circumferential wall portion located on the outside to which the top surface portion is connected. and an alarm driver unit, the alarm driver unit being disposed within a first circumferential wall of the cylindrical body, and the first circumferential wall of the lid being connected to the first circumferential wall of the cylindrical body and a second circumferential wall. between the surrounding wall part, and
In such a way that the second circumferential wall portion of the lid body is located outside the second circumferential wall portion of the cylinder body, there is a gap between the top surface portion of the cylinder body and the top surface portion of the lid body except for the plurality of protrusions. The lid body is connected to the cylindrical body at the projection part so that a gap is formed between the top surface of the cylindrical body and the top surface of the lid body, and the warning sound emitted from the warning sound driver unit is connected to the cylindrical body at the projection part. a path between the first peripheral wall of the cylinder and the first peripheral wall of the lid, a path between the first peripheral wall of the lid and the second peripheral wall of the cylinder, and a path between the first peripheral wall of the cylinder and the second peripheral wall of the cylinder. An object of the present invention is to provide a warning sound device characterized in that the warning sound is configured to be emitted to the outside through a path between the peripheral wall portion and the second peripheral wall portion of the lid.

The electronic circuit described above is a basic example of an alarm sound generating circuit, and is not limited to the electronic circuit having this configuration.

In the alarm device configured as described above, the alarm driver unit 8 is disposed in the cavity 13 of the first cylindrical body 11, and the alarm driver unit 8 is inserted through the through hole 12 of the first cylindrical body 11. The diaphragm 10 is exposed on the top inner wall surface of the first lid body 17, which is arranged so that the peripheral wall faces into the groove 14 around the first cylindrical body 11 in a non-contact state. The electronic sound generated by the diaphragm 10 is blocked by the peripheral wall 17' of the first lid body 17 and the first cylindrical body 1.
The vibration is guided in a zigzag manner along the inner wall surface of the first groove 14, and is finally guided by the inner surface of the peripheral wall of the second lid body 18 to radiate toward the rear wall surface where the alarm device is attached. Even the electronic sound generated by the board 10 can be effectively emitted as a wide-spread electronic sound, that is, as a warning sound.

In particular, the first cylindrical body 1 is used as a guide means for electronic sound.
A groove 14 is formed around the first
The peripheral wall 17' faces the lid body 17 in a non-contact state,
The electronic sound generated by the diaphragm 10 located in front of the first cylindrical body 11 is guided by the groove 14 to the rear from the position of the diaphragm 10 in order to expand the radiation range, so that the electronic sound generated by the diaphragm 10 located in front of the first cylinder 11 is expanded. Compared to the horn-type speaker that is often used in warning sound systems, it is possible to construct a very compact radiating section, and it is extremely effective for use on ships where there are spatial constraints on the installation location of the warning sound system. can.

Furthermore, since the base body 1 is constructed (designed) in a manner similar to that used in a conventional bell-type alarm device, it includes an electronic circuit module 3, an alarm driver unit 8, a first cylindrical body 11, and a first cylindrical body 11. 1 lid body 17, 2nd lid body 17
The lid body 18 (a bell-type bell can also be used for this second lid body) can be used as is by simply replacing it with an electromagnetic relay etc. built into the bell-type. Such an alarm device can be installed at low cost.

Furthermore, since the alarm device of this embodiment is also provided with a light emitting means, even if the electronic sound alarm is difficult to hear due to noise, for example, the light emitting means functions effectively and the alarm can be recognized properly.
