Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a mounting structure for an in-vehicle speaker that is attached to a rear tray or the like in a vehicle.

[Background of the idea]

When in-vehicle speakers are installed at the factory as part of the manufacturing process, they are usually installed on the back inside the rear tray due to considerations such as appearance and interior space. It is very difficult to work because it has to be carried out while supporting the user. Therefore, when installing new speakers after shipping from the factory, it is advantageous to install them from above the rear tray in terms of workability.In order to meet this demand, speakers that can be installed from both the top and bottom of the rear tray are now available. has been done.

FIGS. 5 to 8 illustrate conventional examples of mounting structures for vehicle speakers that can be mounted from both the upper and lower sides. In these figures, 1 is a grill frame, 2 is a net stretched over the grill frame 1, and 3 is a bar-shaped screw without a head. It can be screwed into an embedded embedded nut 4. Reference numeral 5 indicates a support plate disposed inside the vehicle, such as a rear tray, 6 a relatively large opening formed in the rear tray 5, 7 an insertion hole drilled around the opening 6, 8 a speaker, and 9 a speaker. 8, and four insertion holes 7 and four holes 9 are formed each corresponding to the number of screws 3.

FIGS. 5 and 7 are explanatory views when the speaker 8 is attached from the rear tray 5. FIG. In this case, first support the speaker 8 from below the rear tray 5, align the hole 9 of the speaker 8 with the insertion hole 7 of the rear tray 5, and in this state place the grill frame 1 with the screws 3 removed on the rear tray 5. Then, screw the screws 3 through the holes 9 and the insertion holes 7 from below the speaker 8 into each embedded nut 4 of the grill frame 1. Thereafter, the nuts 12 are tightened to each screw 3 via the flat washers 10 and spring washers 11, and the speakers 8 are attached to the back surface of the rear tray 5 as shown in FIG.

When installing the speaker 8 from above the rear tray 5, place the speaker 8 from above the rear tray 5 around the opening 6, place the grill 1 with the screws 3 removed on top of the speaker 8, and then attach the speaker 8 to the rear tray 5. The screw 3 is passed through the hole 9 and the insertion hole 7 from below 5 and screwed into each embedded nut 4. Thereafter, the nuts 12 are tightened to each screw 3 via the flat washers 10 and spring washers 11, and the speakers 8 are attached to the surface of the rear tray 5 as shown in FIG.

The conventional speaker mounting structure described above allows installation work to be carried out with the grille frame 1 and screws 3 separated, so it is suitable for car models with a low rear glass and not enough space between the rear tray 5 and the rear glass. It is very advantageous against. However, since the screw 3 must be screwed into the embedded nut 4 through the hole 9 of the speaker 8 and the insertion hole 7 of the rear tray 5 from below the rear tray 5, there is a problem that the workability is very poor. Furthermore, since the amount of protrusion of the grille frame 1 differs depending on whether the speaker 8 is attached from above or below the rear tray 5, there is another problem in that it is disadvantageous in terms of design.

[Purpose of invention]

An object of the present invention is to solve the problems of the prior art described above, and to provide a mounting structure for a vehicle-mounted speaker that is easy to install and advantageous in terms of design.

[Summary of the idea]

In order to achieve this objective, the present invention provides an in-vehicle speaker in which a grille frame having a net and a speaker covered by the net are attached to a support plate disposed inside the car using screws and nuts. In the mounting structure, the grille frame is provided with a bottom surface having an opening, and an upright wall that can house the speaker is provided on the peripheral edge of the grille frame, and the speaker is placed coaxially with the bottom surface of the grille frame and the speaker. Drill holes for each screw to pass through,
The present invention is characterized in that the net capable of covering these holes is detachably provided on the upright wall of the grill frame.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings.

Figures 1 to 4 explain the mounting structure of a car speaker according to the present invention, with Figures 1 and 2 showing one example of the mounting mode, and Figures 3 and 4 showing other mounting modes. This is an example.

In these figures, 13 is a grill frame, 14 is a net, and 15 is a screw having a head, and parts corresponding to those in FIG. 5 are given the same reference numerals. The grille frame 13 is provided with an opening 16 of approximately the same size as the opening 6 of the rear tray 5, and a plurality of openings 16 (in the embodiment) are formed around the opening 16 so as to be coaxial with the hole 9 of the speaker 8. In this case, four holes 17 are bored corresponding to the holes 9. Further, an upright wall 18 having a diameter larger than the speaker 8 and capable of accepting the speaker 8 is provided on the outer periphery of the grill frame 13.
Cushioning bodies 19 made of plastic rubber or the like are fixed to multiple locations inside the housing 8 . The outer diameter of the net 14 is designed to be somewhat smaller than the inner diameter of the upright wall 18, and the net 14 is designed to have a buffer body 19 as required.
It can be attached to the grill frame 13 via the grill frame 13 or can be separated from the grill frame 13.
The other configurations are the same as the conventional example described above.

Next, the case where the speaker 8 is attached from above the rear tray 5 will be explained based on FIGS. 1 and 2. In this case, first place the grill frame 13 on the rear tray 5 so that the insertion holes 7 and holes 17 are aligned with each other, and the holes 9 and 17 are aligned inside the upright wall 18 of the grill frame 13. Insert the speaker 8 so that it matches. Next, each screw 15 is inserted into the holes 9, 17 and the insertion hole 7 from above in this order, and the nut 12 is tightened onto each screw 15 from below the rear tray 5 via the flat washer 10 and spring washer 11, and the speaker 8 and the grill frame 13 are fixed to the rear tray 5. Finally, standing wall 18
