[Industrial application field]

The present invention relates to a speaker grill that covers a speaker fixed to a rear tray or the like of a vehicle.

Generally, at the rear of a vehicle, a buried camouflage speaker is sometimes used which is placed in a rear tray so as not to obstruct visibility while driving. In order to protect the embedded speaker and improve its aesthetic appearance, the speaker grill is provided on the rear tray surface.

[Conventional technology]

Figures 5A and 5B show the first part of a conventional speaker grill.
FIG. 5A is a perspective view thereof, and FIG. 5B is a sectional view taken along line BB in FIG. 5A.

However, here, the embedded speaker 1 disposed inside the rear tray 9 of the vehicle is shown as a representative speaker applied to the speaker grill 12.

Note that the structure of this embedded speaker 1 is shown in a simplified manner.

In FIGS. 5A and 5B, the main parts of the embedded speaker 1 include a cone 13 that converts electrical signals into sounds and transmits them to the outside, and a magnetic circuit section 14 that drives this cone 13.
It is comprised of a frame 15 that supports the cone 13 and the magnetic circuit section 14. This frame 15 includes an edge portion 16 that connects to the tip of the cone 13 and a gasket 1.
7 and is fixed to a predetermined location of the vehicle, for example, the rear tray 9, by screws or the like. By this fixing work, the above cone 1
The back of cone 3 is sealed inside the rear tray 9, so cone 1
Audio transmitted from the front and rear sides of 3 will not interfere with each other. Therefore, good characteristics are guaranteed in the embedded speaker 1. Since this embedded speaker 1 is directly fixed to the rear tray 9 with screws or the like, it is called a direct-mount type speaker.

In order to protect the cone 13 and the like of this direct-mount type speaker, a speaker grill 12 is arranged above the above-mentioned direct-mount type speaker. The speaker grill 12 is composed of a bowl-shaped cover 20 in which a mesh-like cover portion 2I is formed, and a mounting body for fixing to the above-mentioned direct-mount type speaker. In this case, a fitting groove 23 (FIG. 5B) is formed in the inner peripheral edge of the speaker grille 2 as the mounting body. On the other hand, a protrusion 18 (FIG. 5B) is formed on the peripheral edge of the direct-mount type speaker, and when the speaker grille 12 is pushed in, the protrusion 18 is inserted into the fitting groove 23.
It can be fitted to a direct-mount type speaker.

FIG. 6 is a sectional view showing a second example of a conventional speaker grill. Depending on the vehicle model, as shown in FIG. 7, there is a mounting plate 19 such as a steel plate for fixing the embedded speaker 1 inside the rear tray 9, that is, in the trunk, and a mounting plate 19 for adjusting the height of the mounting plate 19. In some cases, an adjustment shelf 39 having adjustment holes 29 is installed in advance. in this case,
Unlike the first example (FIGS. 5A and 5B), a rib 24 for fixing the embedded speaker l and a boss 25 for fixing the bracket 8 shaped as shown in FIG. 7 are provided.
The speaker grill 22 is used which is formed in advance.

Here, the embedded speaker 1 and the bracket 8 are attached to the rib 24 and boss 25 of the speaker grill 22, respectively, by screws or the like. Furthermore, a double-cut screw 7 is inserted into a tightening hole 80 (FIG. 7) formed in the center of the bracket 8.
By screwing them together and tightening the bracket 8 downward with the wing nut 70 via the mounting plate 19 whose height has been adjusted in advance, the embedded speaker l and the speaker grill 22 are both fixed to the rear tray 9. Ru. Since the embedded speaker 1 is fixed to the rear tray 9 via the bracket 8, it is called a bracket type speaker. In this bracket type speaker, the speaker grill 22
The rear surface of the cone 13 is sealed inside the rear tray 9 by the ribs 24 and tip 26 of the cone 13 . Note that the height of the mounting plate 19 can also be adjusted using flat head screws 49 instead of the mounting shelf 39, as shown in FIG.

[Problem to be solved by the invention]

As mentioned above, conventionally, the first example (Fig. 5A and 5B
Dedicated speaker grills adapted to the direct-mount type speaker and the bracket type speaker in the second example (Fig. 6) and the second example (Fig. 6) were used.

Here, in vehicle models in which the mounting plate 19, the mounting shelf 29, etc. are installed in advance, it is more advantageous for the mounting work to fix the latter bracket type speaker to the rear tray 9.

However, in general, the dimensions of the mounting plate 19, the mounting shelf 29, etc. are not standardized by manufacturers. For this reason, when it is desired to use the desired embedded speaker 1 as a bracket type speaker, this bracket type speaker may not be able to be installed in a certain car model. In this case, it may be possible to use the bracket type speaker described above as a direct-mounted type speaker, but for that purpose, it is necessary to replace the speaker grill 12 dedicated to the bracket type with the speaker grill 22 dedicated to the direct-mounted type speaker. must be installed. As a result, depending on the vehicle type, there arises the inconvenience that two types of speaker grills must be prepared.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a speaker grill that can be applied to both direct-mounted type speakers and bracket-type speakers.

[Means to solve the problem]

The speaker grill of the present invention includes a direct-mounting type mounting body for attaching a bowl-shaped cover 20 to a direct-mounting type speaker by pushing it into the speaker, a bracket-type speaker, and a bracket 8.
The present invention is characterized in that a bracket type mounting body for mounting the cover 20 is integrally formed on the inner surface of the bowl-shaped cover 20.

[For production]

When the speaker grill of the present invention is applied to a direct-mount type speaker, both may be fitted with a direct-mount type mounting body. On the other hand, when applied to a bracket type speaker, after fixing the bracket type speaker and bracket 8 to the above speaker grille with screws etc. to the bracket type mounting body, attach the assembly of the speaker and speaker grille to the vehicle via the bracket 8. It may be fixed to the rear tray 9 or the like.

Thus, according to the present invention, one speaker grill can be shared by different types of speakers, thereby saving the trouble of preparing two types of speaker grills depending on the vehicle type and the like.
