Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a speaker mounting structure, and more particularly to a speaker mounting structure suitable for a vehicle-mounted speaker.
[0002]
[Prior art]
An example of a conventional in-vehicle speaker mounting structure is shown in FIG. The tweeter body 6 shown in FIG. 5 is connected to the case member 7 (fastening with screws or fitting of uneven portions). The case member 7 accommodates a spherical portion 9a provided at the tip of the column 9b of the stand 9, and the spherical portion 9a is held in a compressed state by the case member 7 and the leaf spring member 8 fitted to the case member 7. To do. The stand 9 is formed of two pieces.
[0003]
That is, the tweeter body 6 is supported so as to be rotatable with respect to the stand 9. By placing the stand 9 on a reart ray or the like, the tweeter body 6 can be attached to the vehicle so that the posture can be changed.
[0004]
Another example of a conventional on-vehicle speaker mounting structure is shown in FIG. The convex portion 11 a of the leaf spring member 11 can be fitted into the concave portion 10 a of the tweeter body 10 shown in FIG. 6, and the tweeter body 10 is supported by the leaf spring member 11. The tweeter body 10 can be attached to the vehicle by tightening the screws 5 and 5 inserted through the screw insertion holes 11b and 11b of the leaf spring member 11 to the vehicle interior material 12 such as reart ray.
[0005]
[Problems to be solved by the invention]
In the speaker mounting structure shown in FIG. 5 described above, the mounting method is limited to a method of placing the stand on a reart ray or the like. Also, difficult to speaker angle adjustment range is optimally set the speaker angle adjustment range because it is restricted by interference with the floor to be placed in the case member 7 and the interference and the case member 7 of the stand 9 and a stand 9 Met.
[0006]
In the speaker mounting structure shown in FIG. 6 described above, the mounting method is limited to a method of mounting the speaker in a fixed state, and the speaker cannot be mounted in an adjustable manner.
[0007]
The present invention has been made in view of the above points, and an object of the present invention is to provide a speaker mounting structure in which a speaker mounting method can be selected as either a fixed or rotatable method. .
[0008]
Furthermore, an object of the present invention is to provide a speaker mounting structure in which a rotatable range can be easily set when a speaker is rotatably mounted.
[0009]
[Means for Solving the Problems]
Speaker mounting structure of the invention, the spherical concave portion and the screw insertion hole provided in the plate spring member is fitted to the speaker body, the speaker the body is fastened to the floor or wall by screws through interpolation in the screw insertion hole to allow the Turkey, further, the plate with the spherical recess and the case member of the spring member, sandwiched state forms a turning pair of elastic is applied spherical portion provided at the top of the stand, said by the stand is obtained by allowing the speaker the body is supported in a freely rotating.
[0010]
In the speaker mounting structure, a protrusion that restricts a rotation range of the speaker main body is provided on a spherical portion provided on the top of the stand.
[0011]
Further, in each of the speaker mounting structures, the speaker is a vehicle-mounted speaker.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
A speaker mounting structure according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded sectional view showing a speaker mounting structure according to an embodiment of the present invention, and FIG. 2 is a sectional view showing the speaker mounting structure.
[0013]
The tweeter body 1 shown in FIG. 1 and FIG. 2 is provided with recesses 1a and 1a. By fitting the protrusions 4a and 4a of the leaf spring member 4 into the recesses 1a and 1a, the leaf spring member 4 is tweetered. The main body 1 is fitted.
[0014]
The leaf spring member 4 is provided with screw insertion holes 4b and 4b, and the tweeter body 1 is mounted on the vehicle by screwing the screws 5 and 5 inserted through the insertion holes 4b and 4b into the vehicle interior material as in the conventional example. Can be fixed to interior materials.
[0015]
The leaf spring member 4 can be fastened to the case member 2 by screwing screws 5 and 5 through which the leaf spring member 4 is inserted into the bosses 2b and 2b of the case member 2 as shown in FIG. However, in FIG. 2, the screws 5 and 5 and the bosses 2b and 2b are not shown.
[0016]
When the leaf spring member 4 is fastened to the case member 2, as shown in FIG. 2, the column 3c of the stand 3 is inserted into the slit 2c of the case member 2, and the spherical portion 3a provided on the top of the column 3c is formed. The tweeter body 1 can be rotatably supported by the stand 3 with the elastic force applied between the boss 2 a of the case member 2 and the leaf spring member 4.
[0017]
At this time, the spherical portion 3a, the boss 2a of the case member 2 and the leaf spring member 4 are surely turned to form a pair, and the boss 2a and the leaf spring member 4 are provided with spherical concave portions that coincide with the spherical surface of the spherical portion 3a. Yes.
[0018]
In order to restrict the rotation range of the tweeter body 1 with respect to the stand 3, projections 3b and 3b are provided on the spherical portion 3a. Therefore, as shown in FIG. 3, the case member 2 can be rotated by an angle α from the center position in the horizontal direction. Further, as shown in FIG. 4, the case member 2 can be inclined by an angle β from the horizontal lateral direction by the contact between the support 3c of the stand 3 and the end of the slit 2c. In this way, the rotation range of the tweeter body 1 can be clearly regulated.
[0019]
【The invention's effect】
According to the speaker mounting structure of the present invention, common parts can be used when the speaker is mounted in a fixed state and when it is mounted rotatably. And when attaching rotatably, a rotation range can be defined clearly.
