Description

[Detailed Description of the Invention] The present invention relates to a vehicle-mounted speaker device suitable for a passenger vehicle.

Recently, passenger cars with a hatchback type structure, as shown in Figure 1, have become widely used, and this type of car body can be installed behind the rear seats by opening the rear door. By removing the board, a relatively large space is secured, making it possible to load cargo and passengers (luggage).

Therefore, by attaching and detaching the rear board according to the purpose of use, the vehicle can be used as a passenger vehicle or a freight vehicle.

By the way, when installing an audio device such as a car stereo in these passenger cars, a speaker box is fixed to the board, but since the speaker system is installed facing the part where the board is fixed, However, in the case of stereo, the separation characteristics between left and right channels deteriorated, making it impossible to function satisfactorily as an in-vehicle audio device.

This invention was made in response to the above points,
An in-vehicle speaker device that eliminates the drawbacks of the conventional speaker system by configuring the speaker box so that the mounting angle of the speaker box can be arbitrarily varied in parallel to the mounting panel on the vehicle side when used as a passenger car or a cargo vehicle. The purpose is to provide the following. Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is an assembly diagram showing an in-vehicle speaker device according to an embodiment of the present invention, in which 1 is a speaker unit 2A,
A bass reflex duct (pipe) 5 having a U-shaped handle 3 on the same surface as the side surface 1A to which the bass reflex tube 2B is attached, and a locking protrusion 4 at the base on the side surface 1B separated by approximately 90 degrees from the side surface 1A. The speaker box 6 has a hole 7 for inserting the bass reflex duct 5 and a plurality of guide holes 8A, 8B, 8C, . . . around the hole 7, and screw holes 9A,
An angle adjustment pedestal having 9B, . . . , 10 a rear side panel on the vehicle side having a mounting hole 11 for inserting the bass reflex duct 5 and screw holes 12A, 12B, . . . 13 a movable spring, 14 for mounting. The nut 15 is a mounting screw.

In the above configuration, the speaker box 1
Pass the bass reflex duct 5 through the hole 7 of the angle adjustment pedestal 6 and attach it to the mounting hole 11 of the side panel 10.
The speaker box 1 is attached to the side panel 10 on the vehicle side by inserting the bass reflex duct 5 into the body and tightening the distal end of the bass reflex duct 5 with a mounting nut 14 via a movable spring 13. In this case, by rotating the speaker box 1 around the bass reflex duct 5 using, for example, the handle 3, the locking protrusion 4 can be fitted into any one of the guide holes 8 and locked. Third
As shown in the diagram, attach speaker box 1 to side panel 1.
It can be installed tilted at any angle θ° with respect to 0. The range of this mounting angle θ° can be selected, for example, from 0 to 90°. In addition, the angle adjustment pedestal 6 is attached to the screws 9 and 12 using the mounting screw 15.
It is fixed to the vehicle side panel 10 via. Figure 4 shows the top of the speaker box 1.
Its shape is the vehicle side side panel 1 that should be installed.
Configure it into a deformable box according to the shape and space of 0. As a result, even when the left and right speaker boxes face each other, the speaker units 2A and 2B installed in the speaker box 1 can be directed toward the front seats of the vehicle. FIG. 5 shows the top surface of the angle adjustment pedestal 6 for adjusting the mounting angle of the speaker box.

As described above, if the speaker box 1 is attached to the vehicle side panel 10 via the angle adjustment pedestal 6 using the bass reflex duct 5 as an attachment member, the speaker box 1 can be attached by the combination of the lock protrusion 4 and the guide hole 8. can be attached to the vehicle side panel 10 at any angle. Therefore, by selecting the mounting angle in accordance with the vehicle body structure, desired characteristics can be obtained without deteriorating the separation characteristics of the reproduced sound from the speaker box, whether used as a passenger car or a freight vehicle. Therefore, it is possible to provide satisfactory functions as an in-vehicle audio device.

Note that when attaching the speaker box, it can be done easily and in a short time by using the handle.

This invention is designed with sufficient consideration given to sound separation in the direction of the sound reproduced from the speaker box, especially when used as a freight vehicle, so that satisfactory separation characteristics can be achieved even when the left and right speaker boxes face each other. Obtainable. In addition, even if the present invention is configured with a small-capacity speaker box, since it uses a bass reflex duct that also serves as a mounting member, it can improve the high output and sound quality problems caused by the small capacity of the box, so it can be used as a speaker. Desired performance can be maintained.
