[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a speaker device. In detail, a rib is provided on the back surface of the frame body for attaching the net, and a groove is formed on the mounting surface of the speaker. The rib is press-fitted. Can be attached.
[0002]
[Prior art]
Conventionally, in a general speaker device, as shown in FIG. 7, a net panel 9 for protecting a single or a plurality of speakers (in this example, a single speaker 2) attached to the front of the speaker box 3 is mounted. It is usually done. The net panel 9 has a thin cloth-like net 4 attached to a substantially rectangular frame 5 corresponding to the mounting surface of the speaker 2.
[0003]
Holes 7 are provided at four corners of the mounting surface of the speaker 2, and pins 6 projecting from four lower corners of the frame 5 are press-fitted into the holes 7, and a net panel 9 is mounted. The net panel 9 prevents dust and the like from adhering to the speaker 2 and gives the speaker device 1 a design effect.
[0004]
[Problems to be solved by the invention]
By the way, as shown in FIG. 8, the net panel 9 attached to the conventional speaker device has the net 4 covered by the frame 5 and the sticking portion 13a is heat-sealed with its edge folded into the lower end of the frame 5. It is stuck with adhesive or the like.
[0005]
For this reason, a step of attaching the net 4 to the frame body 5 is required, and the assembling work is troublesome. In addition, when an adhesive is used for attaching the net 4, it is necessary to wait until the adhesive is completely dried, which increases the working time. Therefore, there has been a problem that the working efficiency is poor and the production cost is increased.
[0006]
In view of the above, the present invention has been made to solve the above-described problem, and proposes a speaker device that can attach a net to a speaker device with a simple operation without attaching the net.
[0007]
[Means for Solving the Problems]
To solve the above-mentioned problem, a speaker box to which a speaker is attached,
A net covering the mounting surface of the speaker,
A frame attached to the mounting surface of the speaker to attach the net,
A fixing rib is provided on the back surface of the frame, and a groove is provided on the mounting surface of the speaker where the rib is press-fitted,
By the end of the net is clamped between the rib and the groove, a speaker apparatus nets that are attached,
Fixing holes drilled in the corners of the speaker mounting surface,
A pin provided on the back surface of the frame and pressed into a fixing hole .
[0008]
When assembling this speaker device, the net is placed on the mounting surface of the speaker, and the frame is mounted from above. At this time, the rib of the frame body is pressed into the groove, and the edge of the net is pushed into the groove to be pinched. In addition, the net is pulled outward, so that the net is provided with tension as a whole. Then, the pins of the frame are pressed into the fixing holes, and the frame is mounted and fixed.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, a first embodiment of the speaker device according to the present invention will be described in detail with reference to the drawings.
[0010]
FIG. 1 shows a configuration of a speaker device 10 according to the present invention. The speaker device 10 includes a speaker box 11, a net 13 for protecting the speakers 14a and 14b, and a frame 12 for fixing the net 13 therebetween.
[0011]
The speaker box 11 is a substantially rectangular parallelepiped box body. As shown in FIG. 2, a front surface (speaker mounting surface) 15 is formed with a substantially rectangular protruding surface 22, and two speaker mounting holes 21a, 21 21b is provided. Two large and small speakers 14a, 14b are attached and fixed to the speaker mounting holes 21a, 21b from inside. A rib 17 in the form of a wall is provided around the protruding surface 22, and as shown in FIG. .
[0012]
As shown in FIG. 2, four fixing holes 19 into which pins (not shown) of the frame 12 (FIG. 1) are press-fitted are formed at four corners of the speaker mounting surface 15. In addition, two ducts 20 and 20 are formed in the speaker mounting surface 15 outside the range of the protruding surface 22 to enhance the acoustic effect.
[0013]
As shown in FIG. 1, the frame 12 is provided with a press-fit rib 12a protruding from an inner peripheral side thereof so as to engage with the groove 16, and forms a part of a frame having a U-shaped cross section. Since the press-fitting ribs 12a are press-fitted into the grooves 16, the width thereof is set so as to substantially match the width of the grooves 16. The frame 12 is provided with pins (not shown) which are press-fitted into holes 19 (FIG. 3) at four corners of the rear surface, and duct holes 23, 23 corresponding to the ducts 20, 20 (FIG. 1) are formed. Is established.
[0014]
The net 13 is slightly larger so that the edge thereof protrudes slightly from the outer edge of the rib 17. The end of the net 13 is held by the engagement between the rib 17 and the frame 12.
[0015]
An assembling procedure of the speaker device configured as described above will be described. First, the net 13 is placed on the speaker mounting surface 15 as shown in FIGS. At this time, the edge of the net 13 is set on the rib 17.
[0016]
Next, the frame body 12 is mounted on the speaker mounting surface 15 as shown in FIG. At this time, the press-fitting ribs 12a are press-fitted into the groove portions 16, and the edges of the net 13 are pushed into the groove portions 16. As a result, the net 13 is pulled outward, and is clamped by the engagement between the press-fit rib 12a and the groove 16 in a state where the net 13 is provided with tension as a whole. Then, the pins (not shown) of the frame 12 are pressed into the holes 19 (FIG. 1), and the frame 12 is mounted and fixed.
[0017]
The net 13 can be attached to the speaker box 11 simply by mounting the net 13 and mounting the frame 12 from above. Therefore, unlike the conventional speaker device shown in FIG. 7, it is not necessary to attach the net 4 to the frame 5, so that the assembly can be performed by a simple operation.
[0018]
In this embodiment, two speakers 14a and 14b are attached, but the number of speakers 14a and 14b is not limited to this and may be one or three or more. Alternatively, the frame 12 may be pressed into the speaker box 11 and fixed by means such as bonding.
[0019]
【The invention's effect】
As described above, in the present invention, the net can be attached only by attaching the frame to the speaker box.
[0020]
According to this, there is no need to attach the net to the frame by using an adhesive or heat welding. Therefore, since the speaker device can be assembled in a short time, work efficiency is increased, and production costs can be reduced. In addition, if the frame is attached to the speaker box by press-fitting only, even if the net breaks for some reason, the frame can be removed and the net alone can be replaced. Can be performed.
