Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved structure for mounting a speaker, particularly to a rear tray of an automobile.

Conventionally, in order to attach an in-vehicle speaker to a member such as a rear tray or rear seat hardware, the peripheral part 2 of the speaker frame 1 is attached using screws 3 as shown in Figure 2a. You can attach it directly to the rear tray 4 by screwing it in, or as shown in Figure 2, for a U-shaped attachment, use a hardware 5 with screws 6 protruding from the lower curved piece. From the aperture hole 7 side where the rear
It was inserted and attached to the tray 4, and the screw 3 was passed through the lower hole 41 of the rear tray 4 and screwed into the screw 6 for installation.

In any of the above cases, since the speakers are attached using screws, it is necessary to provide pilot holes in the rear tray 4 each time.

In addition, the gap between the rear tray 4 and the rear seat iron plate 8 provided below it may differ depending on the type of car or even from car to car. There were cases where it was not possible to install it across the entire army.

Therefore, many steps are required to attach speakers to a member such as a rear tray, and improvements in this process have long been desired.

The present invention was made to improve this point, and a metal material with a spring effect is formed into an S-shape, and the speaker is mounted as a fitting. When attaching a steel plate, etc., insert and attach it to the peripheral edge of the member from the opening hole side formed by the member, and insert the above-mentioned attachment into the gap between the other curved parts of the tool, and insert it into the peripheral edge of the speaker frame. The rising part of the speaker is press-fitted, and the resulting elastic force of the spring causes the mounting tool to strongly clamp the member, and the speaker to be mounted to the speaker is fixed to the member. .

Therefore, the present invention replaces the conventional screw installation.
The speaker is mounted reliably and easily on the member to be mounted, and the speaker is fixedly mounted without using any screws and by the spring force generated in the tool.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of the structure of a speaker mounting device according to the present invention, and FIG. 3 is a perspective view of a speaker mounting device 11 according to the present invention, which is made of a spring material, such as spring steel. It is made of metal materials such as impermeable steel and phosphor bronze, or synthetic resin, and has U-shaped gaps 11a and 11b with mutually different directions in the upper and lower tiers, forming an S-shape as a whole. .

The U-shaped gap 11a is formed in the opening hole 7 so that the rising portion 2a of the peripheral edge 2 of the speaker frame 1 is press-fitted and inserted.
The gap length is slightly smaller than that of a packing layer (not shown) extending over the rising portion 2a or the peripheral edge portion 2 of the frame 1.

The other U-shaped gap 11b is used to sandwich the attached member, rear tray 4 or rear seat iron plate 8,
The gap length is determined by the thickness of the speaker to attach it to the rear tray.

(Fig. 4b) When press-fitting the rising portion 2a into the U-shaped gap 11a, in order to facilitate the press-fitting, the artificial end of the upper clamping piece 11C forming the gap 11a is moved slightly upward. Bend and raise 11d.

Regarding the other gaps 11b, in order to facilitate insertion into the rear tray 4, the tips of the lower clamps 11e in the gaps 11b are slightly bent downward and raised 11f.

(Fig. 4a) The above is an explanation for attaching the speaker to the rear tray, but similar bending steps 11 d' and 11 f are also required when attaching the speaker to the rear seat iron plate.
'.

(Fig. 4b) Note that 9 is a diaphragm.

Next, a description will be given of how to attach a speaker using a device based on the present invention.

In FIG. 5, it is assumed that the three above-mentioned attachments use tools.

For the above-mentioned installation, fittings A, B, and C are inserted into the peripheral edge 7a of the opening hole 7 of the rear tray 4.

At that time, in order to ensure reliable installation against external vibrations,
For attachment, it is desirable that the tools A, B, and C be arranged approximately equally on the peripheral edge 7a.

However, in such an arrangement, the rising portion 2a of the speaker
The above installation is done using the U-shaped gap 11 at the top of each of the fittings.
It is obvious that it cannot be press-fitted or inserted into a.

Therefore, one of the fittings, for example A, should be mounted in advance, and the other fitting should be placed close to one of the fittings, for example C (position A'). 2a
Each of the above-mentioned attachments is press-fitted into the upper U-shaped gap 11a of the tool.

Next, the mounting tool A is strongly rotated in the direction of the arrow from the illustrated position A' along the periphery. Once they are pressed together, they can be rotated, and the mounting tools A, B, and C can be arranged at approximately equal intervals.

For installation, insert the tool 11 into the peripheral edge 7a of the rear tray 4, press the rising part 2a of the frame into the upper gap 11a (Fig. 4a), and then the upper clamping piece 11C will move in the direction of the arrow ( As a result, an elastic force is generated, and the bottom of the upper gap 11a tries to bend in the direction of the arrow (counterclockwise), strongly pressing the rear tray 4.
The rising portion 2a is press-fitted and held in the upper gap 11a.

At the same time, the rear tray 4 is firmly held by the lower gap 11b, and as a result, it is possible to securely attach the speaker to the rear tray 4.

Further, as shown in FIG. 4, when attaching the speakers to the rear seat iron plate 8, it can be done in exactly the same way as the case of attaching the rear tray described above.

In the above case, the explanation was given for the case where there are three speaker mounting devices, but the number may be two or more, but it is important to take into account the vertical and horizontal vibrations that will be applied to the speaker. If so, three or more are preferable.

In addition, in the above embodiment, the rising portion 2 of the speaker frame
Although the case where a is formed over the entire circumference of the peripheral edge portion 2 of the frame has been described, the same applies to the case where the rising portions are formed at equal intervals on the peripheral edge portion.

Since the speaker installation according to the present invention has the above-mentioned configuration, there is no need to use any screws for installation as in the conventional example, and there is no need to prepare a hole for this in the member to be installed. disappears.

Therefore, installing spill force is easier and easier than before.
This can be done reliably and the number of man-hours required for installation can be significantly reduced.

When installing, it is possible to prevent accidents such as using a screwdriver to tighten the screws as in the conventional example, such as damaging the diaphragm with the screwdriver.
This is extremely useful in practice.
