Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker unit mounting device for mounting a speaker unit such as a tweeter on a door of a vehicle or a rear board.

[0002]

2. Description of the Related Art As a conventional speaker unit mounting device, a structure shown in FIG. 6 is known. In the figure, the plate-like member 1 is, for example, a car door or a rear board and is provided with an opening 1a. The speaker unit holding member 2 is a member for housing and holding the speaker unit 8, and has a collar portion 4 and a locking hole 3. The speaker unit holding member 2 is embedded in the opening 1a formed in the plate-shaped member 1 and is locked to the edge of the opening 1a by the flange 4. The fixing member 5 is a member that fixes the speaker unit holding member 2 to the plate-shaped member 1, and has a flange portion 6. The fixing member 5 fixes the speaker unit holding member 2 to the plate-shaped member 1 by inserting and tightening the screw 7 into the screw hole 11.

The speaker unit 8 is inserted into the fixed speaker unit holding member 2, and the speaker unit 8
Cords (not shown) are taken out from the hole 12.
After that, when the cap 9 is inserted around the speaker unit 8, the locking claws 10 provided on the cap 9 are locked in the locking holes 3 of the speaker unit 2. As a result, the beauty around the speaker unit 8 is adjusted and
The speaker unit 8 is fixed so as not to jump out of the speaker unit holding member 2.

FIG. 7 is a perspective exploded view of the main parts of FIG. In the figure, a plurality of locking claws 10 are provided on the cap 9, and a locking hole 3 of the speaker unit holding member 2 is formed at a position facing the locking claw 10. Also,
The speaker unit holding member 2 and the fixing member 5 are made of an iron plate diaphragm or a metal plate in order to maintain strength.

[0005]

As described above, in the conventional speaker unit mounting device, the speaker unit holding member 2 and the fixing member 5 are made of iron plate diaphragm or sheet metal, and these members are formed by screws or the like. It is fixed.
Therefore, since the number of parts is large, the number of man-hours is increased, the work is complicated, and the cost is increased.

The present invention has been made in view of the above points, and an object of the present invention is to provide a speaker unit mounting apparatus which is simple in mounting a speaker unit and is low in cost.

[0007]

A speaker unit mounting device according to the present invention is a speaker unit mounting device for mounting a speaker unit in an opening formed in a plate-shaped member, the speaker unit being made of an elastic material. The speaker unit holding member to be housed and held, and the annular fixing member that is made of an elastic material and is wound around the outer periphery of the speaker unit holding member, and the collar portion and the annular fixing member provided on the speaker unit holding member. It is characterized in that it holds the plate member.

[0008]

The operation of the speaker unit mounting device having the above structure is as follows.
A speaker unit holding member made of an elastic material for accommodating and holding the speaker unit, and an annular fixing member made of an elastic material and wound around the outer periphery of the speaker unit holding member, and a flange portion provided on the speaker unit holding member. By holding the plate-shaped member with the annular fixing member,
The speaker unit is fixed.

Therefore, the speaker unit can be easily mounted and the cost of the mounting device can be reduced.

[0010]

Embodiments of the present invention will be described below with reference to FIGS. The same requirements as those in FIG. 6 are designated by the same reference numerals.

In FIG. 1, a speaker unit holding member 21 is a member for housing and holding the speaker unit 8, and is made of an elastic material such as rubber. Further, the speaker unit 21 has a collar portion 22 and a hole 24 for pulling out cords. The speaker unit 8 is housed and held in the speaker unit holding member 21. At this time,
Since the speaker unit holding member 21 is made of an elastic material, the speaker unit 8 is held in close contact with the speaker unit holding member 21. The cords (not shown) of the speaker unit 8 are taken out from the hole 24 to the outside.

The speaker unit holding member 21 holding the speaker unit 8 has an opening 1a formed in the plate member 1.
It is embedded inside and is locked to the edge of the opening 1 a by the collar 22. Then, the annular fixing member 23 made of an elastic material such as rubber is fitted into the outer periphery of the speaker unit holding member 21. The ring-shaped fixing member 23 acts so as to shrink toward the center of the diameter of the speaker unit holding member 21, so that the ring-shaped fixing member 23 is fixed to the speaker unit holding member 21.
It is held firmly in close contact with the outer periphery of the. Since the plate-shaped member 1 is held between the annular fixing member 23 and the collar portion 22, the speaker unit 8 is attached to the plate-shaped member 1.

FIG. 2 is an exploded perspective view of the speaker unit holding member 21 and the annular fixing member 23. Annular fixing member 2
Although 3 is formed in a ring shape, as shown in the sectional view of the annular fixing member 23 of FIG. 5, proper friction can be generated by appropriately selecting the thickness dimension c thereof.

Further, as shown in FIG. 3, the speaker unit holding member 31 is formed by selecting each dimension so that the relationship between the diameter dimension a and the diameter dimension b of the speaker unit holding member 31 is a <b. If so, the speaker unit holding member 3
1 does not pop out.

Further, as shown in FIG. 4, if the groove 42 is formed in the bottom portion of the speaker unit holding member 41, the speaker unit holding member 41 is easily deformed in the dimension d direction, so that there is some variation in the dimension d direction. Even if a certain speaker unit is stored, it can be absorbed.

[0016]

As described above, the speaker unit mounting apparatus according to the present invention has the speaker unit holding member made of an elastic material for accommodating and holding the speaker unit and the speaker unit holding member made of the elastic material wound around the outer circumference. The speaker unit is fixed by sandwiching the plate-shaped member by the collar portion and the annular fixing member provided on the speaker unit holding member, and thus the speaker unit is easily attached. The cost of the mounting device can be reduced.

Further, since the speaker unit holding member is made of an elastic material, the speaker unit is brought into close contact with the speaker unit holding member so as to be housed and held without any looseness, and moreover, unnecessary vibrations are absorbed. ..
