Description

DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention pertains) The present invention relates to a speaker device for both inside and outside of a vehicle, in which a speaker installed inside a vehicle such as an automobile can also be used outside the vehicle. In particular, the speaker box in which the speaker is installed is placed between the in-vehicle use position, where it is supported almost horizontally on the underside of the roof of the car body, and the out-vehicle use position, where it is suspended and supported almost vertically near the rear opening of the car body. The present invention relates to a speaker device that can be moved.

(Background of the invention and problems with the prior art) The speaker box of a car stereo system or the like is often installed at the rear of the vehicle, but in high-roof passenger cars, for example, the speaker box is installed along the bottom surface of the roof. By doing so, the space inside the vehicle can be used effectively, and the speaker box can have a large volume to improve the acoustic effect. Furthermore, in the case of Hatsuchi/Hetsuku vehicles,
If the rear end of the speaker box is supported so that it can be rotated up and down on a horizontal axis in the left-right direction of the vehicle body, for example, as shown in Japanese Utility Model Application Publication No. 58-11570, When camping or picnicking, open the tailgate and rotate the speaker box downwards.
By directing the speakers toward the rear outside the vehicle, it becomes possible to enjoy music and the like using the automobile stereo device even outdoors.

By the way, when listening to music or the like using a stereo device, it is generally preferable for the speaker box to be located in front of the listener in terms of acoustic effects. Even if it is not possible to install the speaker box in front of the listener, it is desirable to position the speaker box as close to the listener as possible.

If the speaker box is to be installed along the lower surface of the roof inside the vehicle interior as described above, the speaker box should be located far forward of the rear end of the vehicle interior, near the center of the vehicle interior, for example, near the top of the rear seat. be able to place it. Therefore, in the above-mentioned speaker device for both interior and exterior use, the speaker box is installed near the center of the vehicle interior, and its rear end is pivotally supported on the vehicle body.
It is conceivable to rotate it vertically at that position. However, in this case, even when the speaker box is lowered, the speaker box will be suspended and supported at a position far forward from the rear opening of the vehicle, which means that you can listen to music etc. outside the vehicle. Unable to find a suitable position for listening. When used outside the vehicle, it is desirable that the speaker box be supported at a position as close as possible to the rear opening of the vehicle body.

In this way, one speaker box is placed near the center of the vehicle interior when used inside the vehicle, and is supported close to the rear opening of the vehicle body when used outside the vehicle. One way is to attach a long arm that extends backwards to the speaker box.
It is conceivable that the rear end of the arm is supported by a horizontal shaft provided on the underside of the roof at the rear end of the vehicle body, so that the speaker box can rotate vertically around the horizontal shaft. . However, if this is done, the radius of rotation of the speaker box becomes large, and when the speaker box rotates, it comes into contact with the seatback of the rear seat, luggage in the trunk room, and the like. Therefore, in that case, the seat back must be folded down or the luggage must be removed each time. Further, when such a speaker box is used outside the vehicle and is suspended vertically, it is located at the lower part of the rear opening of the vehicle body, which is not desirable in terms of acoustics.

(Object of the Invention) The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a speaker box that is supported almost horizontally at a position in front of the vehicle interior when used inside the vehicle, and when used outside the vehicle. To be able to move between two positions, such as being supported almost vertically at a position close to the rear opening of the vehicle body, and to avoid interfering with the rear seat, etc. when moving. It is.

(Characteristics of the Invention) In order to achieve this object, in the present invention, the horizontal shaft that supports the speaker box so as to be rotatable in the vertical direction is positioned at a position forwardly away from the rear opening of the vehicle body and at a position close to the rear opening of the vehicle body. It is possible to move between.

In order to make the horizontal axis movable in this way, for example,
It is conceivable that the horizontal shaft is supported slidably along a guide rail, or that the horizontal shaft is supported by a link arm that swings between two positions.

In this way, the speaker box can be rotated vertically around its horizontal axis and then moved forward and backward, or moved forward and backward and then rotated up and down. Furthermore, since it will be possible to rotate the speaker box vertically while moving in the front-rear direction, the speaker box will be able to rotate vertically at the bottom of the movement path, as in the case where a headrest is provided on the seat back of the rear seat. Even if there is a high obstacle, it will be possible to pass over it.

(Example) Hereinafter, the present invention will be explained in detail based on the drawings.

1 to 3 show an embodiment of a speaker device for both interior and exterior use of a car according to the present invention, and FIG. 1 is a schematic side view of an automobile equipped with the speaker device, and FIG. 3 is a rear view cut along the line ■--■ in FIG. 2.

As is clear from FIG. 1, this automobile 1 is a high-roof type hatch pack vehicle, and a rear opening 3 of the vehicle body is opened and closed by a tailgate 2 that is rotated in the vertical direction. A guide rail 5 is provided on the rear lower surface of the roof 4 of this automobile 1, and extends forward from a position close to the rear opening 3 of the vehicle body. , is supported so as to be slidable in the front-back direction. A support bracket 7b fixed to the rear end of the speaker box 7 is rotatably supported on the horizontal shaft 6, so that the speaker box can be rotated in the vertical direction about the horizontal shaft 6. It is like that.

To explain the speaker device in more detail with reference to FIGS. 2 and 3, the lower surface of the roof 4 at the rear of the vehicle body has a width close to the width of the vehicle interior, and extends from the rear end of the vehicle interior to the center of the vehicle interior, i.e. Four parts 9 are provided that extend in the front-rear direction up to the vicinity directly above the rear seat 8. The guide rail 5 is fixedly supported by the left and right side walls of the recess 9, and its front end is located forward of the seat back 8a of the rear seat 8, and its rear end is located at the rear end of the recess 9, i.e. It is arranged to be located close to the rear opening 3 of the vehicle body. The guide rail 5 has a channel shape, and the slider 1O is slidably supported by the groove. Both ends of the horizontal shaft 6 are supported by the slider 10, so that the horizontal shaft 6 can be moved in the front-rear direction along the guide rail 5 from the front position to the rear position.

When the slider 10 reaches the front end of the guide rail 5,
That is, when the horizontal axis 6 is at the front position farthest forward from the rear opening 3 of the vehicle body, the speaker box 7 is placed on the roof 4.
When the speaker box 7 is rotated upward until it is almost horizontal along the bottom surface, the speaker box 7
is just accommodated in the recess 9. In order to keep the speaker box 7 in this state, a locking device (
(not shown) is provided.

Inside the speaker box 7, speakers 7a and 7a are provided on the left and right sides, respectively.
When the speaker 7a is supported in a substantially horizontal state, the speaker 7a faces the interior of the vehicle. Further, when the speaker box 7 is rotated downward and suspended in a substantially vertical state, the speaker 7a faces rearward outside the vehicle.

Next, the operation of the speaker device configured as described above will be explained.

The cloth is held in a substantially horizontal stored state at the forwardmost position of the recess 9, as shown by the two-dot chain line in FIG.

Therefore, at that time, the speaker 7a is positioned close to the center of the vehicle interior and faces the interior of the vehicle, and music is played from immediately behind the front seat occupant and slightly in front of the rear seat 8 occupant. Sound effects are now available.

When listening to music or the like outside the vehicle, the vehicle 1 is parked and the tailgate 2 is rotated upward to open the rear opening 3 of the vehicle body.

After the speaker box 7 is rotated downward, it is moved rearward until the horizontal shaft 6 reaches the rear end of the guide rail 5. If you let go of the speaker box 7 in this state, the speaker box 7 will be suspended and supported in an almost vertical state due to its own weight, and the speaker 7a will be located at a position close to the rear opening 3 of the vehicle body and will face toward the rear outside the vehicle. Become. Therefore, the speaker box 7 can be used even outside the vehicle, and the speaker box 7 can be used while moving the speaker box 7 in the front-rear direction in this way. In this case, when the seat back 8a of the rear seat 8 is low, the speaker box 7 can be moved even in the lowered state. If the seat back 8a is high or a high headrest is attached, the speaker box 7 can be tilted to allow the speaker box 7 to pass over the seat/header 8a. That is, when there is sufficient space behind the seat back 8a, the speaker box 7 is moved in a nearly horizontal state or slightly rotated downward and tilted, and then rotated further downward behind the seat back 8a. so that it is suspended almost vertically. Further, when there is sufficient space in front of the seat back 8a, the speaker box 7 is rotated by 80 degrees or more at the front position and moved in a rearward tilted state. After passing through the seat back 8a, the speaker box 7 is rotated in the opposite direction so that it is suspended almost vertically.

In this way, the speaker box 7 can be used at an in-vehicle use position near the center of the vehicle interior, where it is supported almost horizontally along the lower surface of the roof 4, and at a position near the rear opening 3 of the vehicle body, where it is suspended and supported almost vertically. It will be possible to move it between the outside of the vehicle and the use position outside the vehicle.

Furthermore, if the kite rail 5 is made to have a path that curves in three directions, even if the speaker box 7 is lowered almost vertically, the high seat/head 8a
It becomes possible to pass above the . As a mechanism for allowing the speaker box 7 to pass above the seat back 8a in a lowered state in this way, it is also possible to use a link mechanism.

4 and 5 show another embodiment of the present invention using such a link mechanism, with FIG. 4 being a longitudinal sectional side view thereof, and FIG. 5 being a schematic perspective view thereof. In addition, in these figures, the same reference numerals are given to the same parts as in the embodiment of FIGS. 1 to 3.

As is clear from these figures, the lower surface of the roof 4 at the rear of the vehicle body is provided with a recess 9 similar to the embodiment shown in FIGS. A support frame 20°20 is fixedly supported. This support frame 20 is provided with a bracket 21 on its upper surface, and stoppers 22a and 22b that protrude inward are provided at a certain distance before and after the bracket. The bracket) 21 has a horizontal short shaft 23 that protrudes inward.
is attached, and a base end portion of a link arm 24 is rotatably supported at the tip of this short shaft 23. The position of this short axis 23 is the seat back 8'a of the rear seat 8.
It is desirable to set it almost directly above.

The link arm 24 is moved from the horizontally forward position at the opening 0 mountain to the horizontally rearward position when the link arm 24 is moved out of the swinging bamboo link by stoppers 22a and 22b provided on the support frame 20. To the position, Habo 1
It can swing 80 degrees. A horizontal shaft 6 having an axis in the left-right direction of the vehicle body is attached to the tip of the link arm 24, and as the link arm 24 swings, the horizontal shaft 6 moves from the front position to the rear position close to the rear opening 3 of the vehicle body. It is now possible to move up to A support bracket (7b) fixed to the speaker box 7 is rotatably supported on this horizontal shaft 6, so that the speaker box 7 can be rotated vertically about its horizontal shaft 6. ing. Left and right stoppers 22a.

22a; 22b, 22b and short axis 23.23(7) intervals are larger than the width of the speaker box 7 in the left-right direction, so that the speaker box 7 can pass between them.

When the link arm 24 is locked to the front stopper 22a, the horizontal shaft 6 is at the farthest forward position from the rear opening 3 of the vehicle body, and the speaker box 7 cannot be rotated upward at this position. As a result, the speaker box 7 is housed in the recess 9 and supported in a substantially horizontal position along the lower surface of the roof 4. The speaker box 7 is normally used in this state as an in-vehicle speaker box.

When using the speaker box 7 outside the vehicle,
Rotate it downward from its storage position until it is almost vertical, and then push it up. Then, the link arm 24 swings about the short axis 23, and the horizontal axis 6 draws an arcuate locus curved upward. When the link arm 24 is thus rotated to the position where it is stopped by the rear stopper 22b, the horizontal shaft 6 moves to the rear position, which is the rear end of the recess 9, and the speaker box 7 is moved to the outside use position, that is, at the rear of the vehicle body. It comes to be suspended and supported almost vertically at a position close to the opening 3. During this period, the lower end of the speaker box 7 traces a trajectory similar to the horizontal axis 6. Therefore, when the speaker box 7 moves in the front-back direction, it rises once and then falls again, so that it passes above the seat back 8a without interfering with it. When the speaker box 7 is used inside the car or outside the car, the link arm 24 is supported at the lowest stable position, so the speaker box 7 is kept in a stable state. will be retained.

Note that - in the above embodiment, the speaker box 7 is positioned forward of the seat back 8a of the carrier seat 8 when used in a car; Even if the present invention is installed, the present invention is extremely useful in a speaker device for both interior and exterior use installed in a vehicle with a long luggage compartment, such as a station wagon or a light van.

(Effects of the Invention) As is clear from the above description, according to the present invention, the speaker box, which is supported almost horizontally along the lower surface of the roof inside the vehicle interior, can be moved up and down on the rear end side by a horizontal axis in the left-right direction of the vehicle body. The horizontal axis can be moved forward and backward from a position close to the rear opening of the car body to a position ahead of it, so when used inside a car, The speaker box can be positioned sufficiently forward in the vehicle interior so that the speaker faces into the vehicle interior, and when used outside the vehicle, it can be suspended almost vertically near the rear opening of the vehicle body. The speaker can be supported so that the speaker faces toward the rear outside the vehicle. Therefore, the speaker box can be held at an optimal position both when used inside the vehicle and when used outside the vehicle.

Furthermore, even if there is a high obstacle such as a seat back, the vehicle can be passed over it without interfering with it.
