Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a speaker packaging device for protecting a diaphragm during packaging or transportation of the speaker.

(b) Conventional technology Conventionally, in order to prevent the diaphragm (cone paper) from being damaged or deformed during packaging or transportation of the speaker, or to prevent the edge treatment agent applied to the cone edges from falling off, A protective plate is placed on the front of the speaker, and the speaker and protective plate are housed in a packaging bag (for example, a plastic bag). However, the protective plate may rub the speaker frame and damage the painted surface of the frame, so either fix the protective plate and the speaker frame with adhesive tape, etc., or store them in a plastic bag and seal them tightly with adhesive tape, etc. There is a need to. Therefore, there are problems in that the work is difficult, requires a lot of man-hours, and is uncertain.

(c) Problems to be solved by the invention This invention solves the above-mentioned problems, namely, that the work of fixing the protective plate and the speaker frame is difficult, takes many man-hours, and is uncertain. be.

(d) Means for solving the problem The present invention includes a first slit having a convex portion toward the center at a position corresponding to one end of the speaker, and a first slit having a convex portion toward the center at a position corresponding to one end of the speaker. A second slit opposite the first slit is provided at a position corresponding to the end, both ends of the speaker are held between the first slit and the second slit so as to be exposed, and the convex portion of the first slit is shaped like a flange of the speaker. It is brought into contact with the stepped portion of the frame and stored in the packaging bag with the first slit side facing first.

(E) Function The first slit has a convex portion toward the center, and the convex portion abuts the stepped portion of the flange-shaped frame, so that the speaker frame is connected to both ends of the first slit and the three convex portions
The first slit is stably supported by the points, and the first slit is prevented from expanding due to the flange of the frame.

(f) Examples The present invention will be explained below with reference to FIGS. 1 and 2. FIG. 1 is a plan view of a protection plate according to an embodiment of the present invention.

The protection plate 1 is formed of, for example, cardboard into a substantially square shape, and has sides larger than the maximum outer diameter A of the packaged speaker. The protection plate 1 has a first slit 3 having a convex portion 3C toward the center C at a position corresponding to one end of the packaged speaker, and a parallel straight line facing the first slit 3 at a position corresponding to the other end. A second slit 4 is provided.

Both ends 3a and 3b of the first slit 3 are located on the maximum outer diameter A of the packaged speaker, and both ends 4a and 4b of the second slit 4 are similarly located on the maximum outer diameter A of the packaged speaker. Corner 2 of protection plate 1,
2 is formed into a circular arc shape and is marked with a so-called R.

FIG. 2A is a side view of the packaged speaker 5 with the protective plate 1 attached thereto, and FIG. 2B is a bottom view of the same. The speaker 5 is provided with a field part 8 and a flange-shaped frame 9, and the frame 9 has a flange part 6 and a step part 7. Both ends 6a and 6b of the flange 6 of the frame 9
is held between the first slit 3 and the second slit 4 of the protection plate 1 so as to be exposed, one end 6a of the flange is in contact with both ends 3a, 3b of the first slit 3, and the other end 6b of the flange is in contact with the second slit 3. Both ends 4 of 2 slit 4
a, 4b.

Furthermore, the convex portion 3c of the first slit 3 abuts against the stepped portion 7 of the flange-shaped frame 9. Therefore, when inserting the speaker 5 into the packaging bag 10 in the direction of the arrow, this protrusion 3c acts as a stopper, and the frame 9
One end 6a of the flange is both ends 3a of the first slit 3,
3b is prevented from expanding.

Note that without this protrusion 3c, both ends 3a and 3b of the first slit 3 of the protection plate 1 would expand, causing the frame 9
The inner side of the flange 6, that is, the diaphragm (not shown) is exposed from the protection plate 1. As a result, problems arise such as the diaphragm being damaged or the edge treatment agent applied to the edges (not shown) of the diaphragm coming into contact with the packaging bag 10 and falling off.

Therefore, the distance B from the opposite sides 11 and 12 of the protection plate 1 to the first slit 3 and the second slit 4,
D is set to be less than or equal to the width of the flange portion 6 of the frame 9.

Further, since the corners 2, 2 of the protection plate 1 are rounded, the packaging bag 10 is not damaged by the sharp corners, and insertion is easily performed. As shown in Fig. 3, the second slit 4 is shaped to be symmetrical to the first slit 3, and all the corners 2, 2, 2, 2 of the protection plate 1 are rounded to make the protection plate 1 symmetrical. It may be shaped.

Furthermore, round holes 3d are provided at both ends 3a, 3b of the first slit 3 and at both ends 4a, 4b of the second slit 4.
By providing 3e, 4d, and 4e, it becomes easier to insert the flange 6 of the frame 9 into the slit. If the speaker has a substantially circular flange-shaped frame,
Needless to say, the shape may be circular.

(g) Effects of the invention As explained above, according to the invention, by providing the first slit and the second slit in the protection plate, there is no need to use adhesive tape, etc., and the protection plate can be easily connected to the speaker. It can be installed securely on the
