Description

[Detailed description of the invention] The present invention provides a speaker that is easy to install even in cases such as in automobiles, where the installation angle of the speaker is required to be adjustable and the mounting base surface lacks flatness. This relates to the mounting structure.

2. Description of the Related Art Conventionally, speakers used in places where directivity of amplified sound is required, such as in automobiles, have been designed to be adjustable in angle when installed.

However, for speakers used in relatively narrow spaces such as inside a car, it is not always possible to choose a flat place as the base surface, and there are cases where it is necessary to install the speaker in a place that usually has a stepped part, such as the rear bar cell tray. This is what happens.

In such a case, difficulty arises in the installation stage before the angle adjustment means is installed.

Here, in the front and rear of the speaker unit, the present invention first provides a latch pawl on the bracket side as the rear side means, and correspondingly, a plurality of latch recesses are provided on the speaker unit side. One of the plurality of latching recesses is selectively latched to one of the latching recesses, and the front side means includes a plurality of through holes bored in the bracket, and a plurality of through holes formed in the bracket. A screw hole is formed in the side of the speaker unit correspondingly to the screw hole, and one of the plurality of through holes is selectively screwed into the screw hole, and thereby It is an object of the present invention to provide a speaker mounting structure that allows accurate mounting even when the mounting base surface has a stepped portion, and also allows angle adjustment.

The present invention will be explained in detail below based on the embodiments shown in the drawings.

Figure 1 is an exploded perspective view of the present invention. In the figure, symbols B, B2 are opposed plate-shaped brackets, and a long plate-shaped fixing plate is attached to the lower end of both brackets B, B2. 1 across the rack, and both brackets on this fixed plate 1) B,,B
2 to the base (described later).

When installing both brackets B1. The speaker unit S is sandwiched between the rackets B1 and B2. Bracket Bl serves as a means for fixing to B2.

B2 to speaker unit) S is provided with front side means and rear side means.

First, as the rear side means, both brackets B1. B
Latching claws 2, 2 formed by, for example, bent portions are provided at the rear ends of the latches 2, respectively, facing inward.

In addition, when the fixing plate 1 is fixed to a flat surface as shown in FIG. Place it at a height.

On the other hand, on the back side of the speaker unit S, a plurality of latching recesses 3 are provided in the height direction (vertical direction in the figure) for one latching pawl 2 to fit into. Individually placed.

Although the figure shows the case where two latching recesses 3 are provided, the number may be three or more as appropriate.

Next, as the front side means, first, the bracket B1. B2
A plurality of (three in the illustrated example) through holes 4 are bored in the portion.

The drilling positions of the through holes 4 are separated by an appropriate distance from the latching pawl 2, and each through hole 4 is located at the installation point of the latching pawl 2 (to be precise, They are located approximately on the same radius around the latching point between the stopper 2 and the latching recess 3.

On the other hand, the above-mentioned transparent 7L4 is installed on both sides of the speaker unit l-5.
. . . Screw holes 5, 5 for screwing and fixing the speaker unit S with screws 6 are bored through any one of them.

Next, a description will be given of how the speaker unit (S) is mounted using each member configured as described above.

■ When the base is flat (Figure 2).

First, the fixing plate 1 is fixed at a predetermined position on the base 7 by suitable means such as screws.

Next, any one of the plurality of latching recesses 3 is selected and the latching pawl 2 is latched thereto, but normally the upper latching recess 3 is selected. Select this and hook it with the latch 2, so that the speaker unit (S) is in a lowered position (closer to the base 7).

As mentioned above, first position the speaker unit (S) in the height direction at the rear, and then select the desired through hole 4 from among the multiple through holes 4 on the front side. , fix the front part of the speaker unit (S) to the bracket (B), B2 with the screw 6 through the through hole 4, and then attach the speaker unit (S') to the bracket (B), B2.
The direction of the image is determined at a predetermined angle.

When the base of the O-mounting part has a step (Fig. 3).

As shown in FIG. 3, when the base 7 is formed of a stepped part such as the rear parcel tray of an automobile, and the fixing plate 1 is fixed to the lower side of the base, the base 7 is located at a lower position. Hook the latch claw 2 into the latch recess 3 and attach the speaker unit)S
The lower surface of is raised above the lower side base surface 7'.

This prevents the lower surface of the speaker unit S from coming into contact with the stepped portion 7' of the base, allowing the speaker unit to be properly mounted.

Next, the orientation of the speaker S' is determined at a predetermined angle using the through holes 4, screws 6, and threaded holes 5 on the front side, as in the case of item 0 above.

As described in detail above, according to the present invention, first, the rear side means is attached to the front and rear of the bracket or the speaker unit by floating the rear end of the bracket by an appropriate distance above the position of the bracket fixing plate. In addition to providing a stopper, a plurality of hooking recesses are also provided on the rear surface of the speaker unit, and a plurality of through holes are provided on the bracket as the front side means, and a plurality of through holes are provided on the side of the speaker unit. The speaker unit is attached to the bracket with screws etc. by drilling a threaded hole in the part and selectively passing through the desired hole, so the mounting height can be adjusted freely and the mounting angle can also be adjusted. Therefore, even if the base has a stepped part, such as the rear parcel tray part of an automobile, it can be mounted accurately at the desired angle, and it has versatility in the mounting location. Demonstrates extremely excellent effects.
