Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a speaker mounted on a package tray behind a rear seat, a so-called rear speaker.

[Conventional technology]

A well-known speaker of this type has an appearance of an isosceles triangular shape in the longitudinal direction of the vehicle body, and has a speaker main body inside. A sound output net is provided on the front of the instrument, allowing for high-quality performances.

[Problem that the invention attempts to solve]

However, it can be noisy for rear seat occupants when listening in the front seats with adequate sound output. In this case, the volume may be reduced, but it will not be possible to hear a high-quality performance under sufficient acoustic output.

In view of this point, the present invention aims to provide a speaker of the type mentioned at the beginning that reduces the loudness of the speaker for rear seat passengers without impairing the sound quality at the front seat riding position. .

[Means for solving problems]

In order to achieve this objective, the present invention provides two sound output nets 11 and 12 above the speaker body 10 attached to the opening 2a of the package tray 2 behind the rear seat 1. A shielding plate 1 is arranged in a substantially isosceles triangular shape in the direction, and shields the acoustic output of one of these nets 11 and 12.
3 is hinged to the apex portion 15 within the triangular shape for external operation.

[Effect]

When the shielding plate 13 is positioned by external operation so as to shield the rear net 12, the acoustic output is output from the front net 11.

If passengers in the back seat feel noisy,
The shielding plate 13 is rotated by an external operation so as to instead shield the net 11 in front. This results in
Passengers in the front seats can hear the performance with sufficient sound output without having to turn down the volume.

The symbols in parentheses refer to the examples described later.

[Example of idea]

1 to 3 show an embodiment of the present invention.

As shown in FIG. 1, the speaker 9 has two rectangular nets 11 and 12 for sound output attached to a substantially isosceles triangular frame 18 in the longitudinal direction of the vehicle body surrounding the net. Inside, the speaker main body 10 is held by a frame 19, and the shielding plate 13 is hinged to an apex portion 15 within the triangular shape so as to be externally operable. Then, the opening 2a of the package tray 2 behind the rear seat 1
The speaker body 10 is placed around the speaker body 10 with screws.
is positioned inside the opening 2a facing upward.

FIG. 2 shows the appearance of the speakers 9, which have a triangular box shape and are arranged in the package tray 2 in the width direction of the vehicle.

FIG. 3 shows the detailed structure of the shielding plate 13.
Pins 20 are attached to both upper sides of the apex portion 15 and are supported on the side surfaces of the frame. A substantially elliptical plate 21 is fixed to the inner pin of the pins 20 on both sides, and a plate spring 22 having two recesses in the longitudinal direction of the vehicle body is attached to the upper apex portion 15 of the plate 21.
is installed. When the upper end 21a of the plate 21 engages with the front recess 22b, the shield plate 13 is positioned at the net 12 shielding position, and when the plate 21 engages with the rear recess 22a, the shield plate 13 is positioned at the net 11 shielding position.

A lever 2 for external operation is attached to the external end of the pin 20.
3 is installed. The lower end of the plate 21 is connected to the upper end of an arm 24 whose central portion is pinned inside the side surface of the frame 18. The lower ends of the levers 24 of both speakers 9 are connected to the upper ends 26a of a U-shaped lever 26, and the middle part of this lever is connected to an inner wire 25 connected to an operating lever (not shown) provided on the front seat. connected to the other end.

The operation of the speaker configured in this way is as follows.

When the upper end 21a of the plate 21 is engaged with the rear recess 22a of the leaf spring 22, the shielding plate 1
3 shields the net 11. In this state, the lever 23 is located at the front, and the lower end of the arm 24 is located at the rear. The passenger in the rear seat presses lever 2.
3 is rotated rearward, the shield plate 13 is rotated rearward, and the upper end 21a of the plate 21 engages with the recess 22b in the front of the leaf spring 22 and is locked.
The rear net 12 is shielded. This switching operation is
This can also be done by the passenger in the front seat moving the inner wire 25 forward using the levers 24 and 26. At this time, the lever 23 is also operated, and by operating these in the opposite direction, the shielding plate 13 can be rotated forward to shield the net 11.

Incidentally, in the above-described embodiment, the switching operation of the shielding plate can be performed simply by an external operation of a switch by using a solenoid valve or the like.

[Effect of idea]

As described above, according to the present invention, by cutting out the sound that directly enters the ears of the passenger in the rear seat position and switching to reflected sound as necessary, it is possible to reduce the noise level and not to impair the sound quality of the front seat occupant.
