Description

[Detailed description of the invention] (Technical field to which the invention pertains) The invention relates to horn speakers often used in large halls and outdoors, and in particular, the invention is designed to facilitate the removal or replacement of insect-proof nets. It's about structure.

(Prior Art) As shown in FIG. 4, a conventional speaker with an insect-proof net has a structure in which the reflector 2 and the insect-proof net 4 are attached to a reflector mounting leg 10 provided on a throat device 8 by tightening them together. (For example, 1987-
189695) (Problem to be solved by the invention) In the case of a speaker with an insect-proof net, dirt or dead insects may adhere to the insect-proof net 4 and block the eyes of the net, so the net should be cleaned regularly. is desirable. However, in the case of the structure shown in FIG. 4, the insect-proof net 4 cannot be removed unless the horn mouth 3 is removed, which makes the work cumbersome.

The present invention provides a structure that allows the insect-proof net 4 to be easily removed and attached, and makes it easy to periodically clean or replace the insect-proof net.

(Means for Solving the Problems) In the present invention, a plurality of mounting legs are provided on an insect-proof net, and the mounting legs are screwed into screw holes drilled in a horn base or a throat tool.
Furthermore, the mounting legs of the insect repellent net are screwed into the screw holes from the horn opening side, and the rear end of the horn mouth is screwed from the horn rear side.

(Function) With the insect-proof net of the present invention, only the insect-proof net can be removed by inserting a screwdriver from the horn mouth opening side and removing the mounting screw. After cleaning the insect-proof net, or by placing a new insect-proof net at a predetermined position between the horn mouth and the reflector from the horn mouth opening side, and tightening the installation screw using a screwdriver, the net can be installed.

(Embodiment) FIG. 1 shows a schematic configuration diagram of a speaker with an insect-proof net according to an embodiment of the present invention. FIG. 2 shows an enlarged cross-sectional view of the insect-proof net attachment part. FIG. 3 shows a perspective view of the insect repellent net.

The embodiment shown in FIG. 1 shows a separate type reflex horn speaker, in which a horn tube 12 is fixed to a horn base 11 by means such as fitting, and a plurality of mounting bases 14 from which a reflector 13 protrudes from the horn base 11. The horn mouth 15 connects the rear end 16 with the screw 1.
Installed in 7. Of course, the driver 18 is attached to the rear of the horn base 11.

As shown in FIG. 3, the insect-proof and bird-proof net 20 is
a ring-shaped frame 21 in contact with the horn mouth 15;
A ring-shaped frame 22 in contact with the reflector 13, three ribs 23 connecting the frames 21 and 22, and the frame 2
Insect and bird prevention net surface 24 stretched between 1 and 22
and a hollow mounting leg 25 vertically planted in the middle of the rib 23. The mounting leg 25 has a length extending from the mounting position of the net 20 to the horn base 11.

After completing the assembly of the horn speaker, the insect-proof net 20 is attached to the frame 22 from the opening side of the horn mouth 15.
While passing the reflector 13 through the frames 21 and 2,
2 into the predetermined position until it touches the reflector 13 and the horn mouth 15. Next, the mounting screw 19, which is longer than the mounting leg 25, is passed through the mounting leg 25 and screwed into the female thread 28 of the horn base 11 to be mounted.

Therefore, by inserting a screwdriver into the opening side of the horn mouth 15 and removing the mounting screws, only the insect-proof net 20 can be removed. After cleaning the insect-proof net 20, or by placing a new insect-proof net 20 in a predetermined position and tightening the mounting screws, the insect-proof net 20 can be installed.

In this embodiment, the rear end 16 of the horn mouth 15
were screwed together using the same female thread 28 for installing the insect repellent net. Therefore, it is economical and
In addition, there are no screw holes left open even when the insect repellent net is not needed, so there is no need to fill them.

Although the embodiment of FIG. 1 shows a separate type speaker, the present invention can be similarly implemented with a combination type speaker. At this time, a female mounting thread 28 is drilled onto the throat tool.

(Effects of the invention) The insect-proof net of the invention can be attached and removed from the opening side of the horn mouth, so it can be easily cleaned.
