BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle speaker mounting structure for mounting a speaker on a fixed portion.

[0002]

In an automobile, a speaker of an audio device is often provided in a door lining, a pillar, an instrument panel or the like inside the vehicle.

[0003] For example, in Japanese Utility Model Registration No. 2604631, a speaker glyph carries punching metal as a speaker cover, and the punching metal projects in such a manner that the edge part is integrally projected with the edge part. On the other hand, the speaker grill has a mode in which the outer ring portion and the inner ring portion are integrally connected by four spokes, and the punching metal is projected at the outer ring side end of each spoke. An insertion hole is formed so that the edge portion can be inserted (Japanese Patent No. 0).
009). On the other hand, a fitting hole for the speaker grill is formed in the front pillar, which is the material to be installed in the speaker grill,
At the periphery of the fitting hole, ears are formed so as to protrude in four directions toward the center of the fitting hole (Gazette No. 0010). Then insert the protruding edge of the punching metal into the insertion hole of the speaker grill, apply the speaker grill to the fitting hole of the front pillar, and insert the protruding edge of the insertion hole of the speaker grill into the mounting hole of the ear. Then, bend the protruding edge portion toward the stop portion of the fitting hole (publication 0012 step),
Attach the speaker grill and punching metal to the fitting holes.

Further, in Japanese Patent Laid-Open No. 8-164799, in a speaker net mounting structure for mounting a speaker net in an opening of a trim part, a plurality of protrusions are formed on the inner peripheral edge of the opening, and the protrusions have a U-shape. Forming a locking hole to form a locking piece that is outward and elastically deformable with respect to the opening, and a plurality of locking pieces corresponding to the protrusions are provided upright on the back surface of the speaker net. And, each of the engaging pieces is formed with a U-shaped locking hole, and the engaging piece is inserted into the locking hole to lock the U-shaped locking piece in the locking hole. (Patent Publication No. 0009)
Dan).

The former conventional technology (utility model registration No. 260)
No. 4631), the edge portion of the speaker cover is inserted and bent in the mounting hole of the ear portion and the ring-shaped speaker grill is fixed in the fitting hole.
Japanese Patent Laid-Open Publication No. 2003-242242), the protrusion of the speaker net is locked to the locking piece of the opening to fix the speaker net. However, a pillar or the like for disposing the speaker has a three-dimensional curved outer surface. Therefore, there is a problem that a gap is likely to be partially formed between the speaker grill and the outer surface of the puller. In the above-mentioned conventional technique, the mounting strength is improved by inserting the edge into the mounting hole of the ear portion, or bending and engaging the protrusion with the locking piece. However, the speaker having the flat rear edge is formed. In order to make the grill or the speaker cover follow the curved surface of the puller, it is expected that an unreasonable force is applied to the speaker grill or the speaker cover at the time of mounting, or an unreasonable force is partially applied after the mounting.

Further, in the former prior art (utility model registration No. 2604631), it is necessary to provide an ear portion in the fitting hole, and in the latter prior art (Japanese Patent Laid-Open No. 8-164799), it is locked in the opening. It is necessary to provide a piece, and since a hole having such a complicated shape is provided at the mounting location,
The processing of the holes is complicated, and complicated work is required to post-process the holes and attach the speaker.

Acoustically, the tweeter in the high frequency range is preferably provided at a substantially central position in the height direction inside the vehicle. Since the tweeter is provided on the front side of the upper part of the front pillar and the door lining, a speaker cover or the like is provided in the puller. In order to mount the speaker cover without using it, it is necessary to form the rear surface of the speaker cover in conformity with the curved surface of the puller, and a dedicated speaker cover is required depending on the mounting position, which is one of the causes of increasing the product cost. Further, if the rear surface of the speaker cover is formed so as to match the curved surface of the puller, it is expected that the direction of the speaker cover must be aligned with the pillar at the time of mounting, and the mounting work will be complicated.

Therefore, an object of the present invention is to provide a mounting structure for a vehicle speaker which is excellent in mounting workability.
