BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotatable speaker grill having improved sound effects and a garnish appearance of a speaker mounted on an automobile pillar, and more particularly, to a rotary speaker grill at any sliding position of a front and rear sliding seat. The present invention relates to a rotatable speaker grill unit that does not obstruct an occupant's view due to rotation of a grill.

[0002]

2. Description of the Related Art Conventionally, it has been common practice to mount a speaker on an automobile pillar. For example,
There is an example disclosed in Japanese Patent Application Publication No. 2-17316. According to the technique disclosed in this publication, two openings are formed in the pillar, a front sound generating surface of the speaker is fixed to one of the openings, and a rear sound generating surface is projected from an outer surface of the pillar, so that the front sound generating surface is protruded from the front surface of the speaker. Is guided into the vehicle interior through another opening through the cavity in the pillar, and the sound emitted from the rear surface of the speaker is directly sent into the vehicle interior. With such a configuration, a phase inversion type speaker system is obtained, and the quality of bass is improved.

On the other hand, as shown in FIG. 7, a speaker 1 is mounted on an iron plate pillar 2 of an automobile, and a speaker grill 4 separate from the speaker 1 is provided in an opening provided at a position corresponding to the speaker in a pillar garnish 3 which covers the pillar. The fixed mounting method is used in various types of automobiles. In the speaker grill 4 mounted on the opening, a hole for emitting sound into the vehicle cabin is formed on the grill surface which is flush with the garnish surface which does not obstruct the occupant's view.

[0004]

However, in the prior art disclosed in the above publication, the rear sound generation surface of the speaker must be protruded from the pillar surface, and the appearance is poor. Is covered with a cover, and sound is output from a hole formed in the upper part of the cover. However, still poor appearance protrude from always the pillar surface naturally speaker and the cover in this manner, moreover vision obstruction range theta _F speakers windshield as shown in FIG. 8, will enter the theta _R, occupant's view Hinder. Further, since the sound is emitted along the pillar surface and not toward the occupant's ear, the stereo effect produced by the left and right speakers is reduced.

On the other hand, the method of mounting the speaker grille 4 in the opening of the pillar garnish 3 solves the problems of appearance and occupant visibility, but the sound is emitted in the vehicle width direction or the windshield direction. Therefore, the problem of the stereo effect cannot be solved as in the method disclosed in the above publication.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and its object is to provide an excellent appearance and a sufficient stereo effect, and to be able to be used at any position of the front and rear sliding seats. An object of the present invention is to provide a rotary speaker grill unit that does not hinder the occupant's view.

[0007]

In order to achieve the above-mentioned object, the main structure of the present invention is to be rotatable around a front edge of an opening formed in a pillar garnish at a position corresponding to a speaker mounted on an automobile pillar. A speaker grill unit that is rotatably supported by the loudspeaker, the grill surface of which emits the sound into the passenger compartment is exposed toward the occupant when the unit is rotated and opened, and is stored in the garnish when the unit is closed. In any sliding position of the front / rear sliding type seat, there is provided a restricting means for restricting the rotation angle of the unit so that the rotation of the unit does not increase the obstruction range of the occupant. It is characterized by:

[0008]

[Function] When the speaker is used, if the surface of the speaker grill unit on the vehicle interior side is pressed, the lock is released and the grill unit is automatically rotated around the pivotal support part by the spring force to the limit of rotation. The surface is exposed toward the occupant. The sound from the speakers is reflected by the sound reflecting surface of the grill unit, guided through the grill surface and reaches the occupant's ear, and the sound from the pair of left and right speakers is combined to produce a stereo effect. When the speaker is not in use, press the surface of the speaker grill unit on the vehicle interior side,
The speaker grill unit rotates against the spring force and is stored in the pillar garnish opening, and is automatically locked at the same time, so that the unit surface and the garnish surface are flush.

The rotation of the speaker grill unit is limited by the rotation restricting means, so that the occupant's obstruction range is not increased.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. 1 to 9 show a typical embodiment of the present invention.

FIGS. 1 and 2 are explanatory views of the operation of the speaker grill unit of the present invention mounted on the front pillar garnish. In these figures, the plastic pillar garnish 3 has flanges on both sides of the inner panel 2b and the outer panel 2a. Welt 6 attached to the front flange of front pillar 2 formed by welding,
The one side end 3a is fixed to the inner panel 2b so as to abut. Reference numeral 7 denotes a windshield, and 7a denotes a painted opaque area of the glass 7.

A speaker 1 is fixed to the vehicle interior surface of the inner panel 2b. A rotating shaft 8 is provided at a front edge 3b of an opening formed at a position of the pillar garnish 3 facing the speaker. A front end of the grill unit 4 is rotatably supported by a shaft.

The speaker grill unit 4 is shown in FIG.
As shown in FIG. 5, the upper and lower wall surfaces are substantially fan-shaped, and the arc-shaped portion is provided with a grill surface 4a having a plurality of slits for emitting sound into the vehicle interior, and at a position facing the sound generation surface of the speaker 1. Is provided with an acoustic reflection surface 4b, and the sound from the speaker 1 is reflected by the acoustic reflection plate 4b and guided toward the grill surface 4a.

1 and 2, the F / M and R / M positions indicate the positions of the eyes when the occupant is seated in a normal posture at the front and rear limits of the front and rear sliding seats of the vehicle, respectively. The visual field obstruction range at the position is indicated by θ _F and θ _R. At the rear end of the speaker grill unit 4, a stopper 4c for restricting the rotation angle of the speaker grill unit 4 so as not to protrude from the visual field obstruction ranges θ _F and θ _R is projected. The garnish opening is locked to the rear edge.

FIG. 4 is a view taken along the line BB of FIG. 3 and shows an example of a push-lock / push-release type locking device. Reference numeral 10 protrudes from the upper edge of the speaker grill unit 4 to the outside of the passenger compartment. Reference numeral 11 denotes the engaging member 1 attached to the upper edge of the opening of the garnish 3.
