This mounting structure has a magnetic circuit section S1 of the speaker unit S,
In particular, a center bolt 26, which is adapted to be screwed into a nut 27 fixed to the bottom surface side of the yoke S2, is passed through a hole 25 formed in a stay 24 having a U-shaped cross section, and is arranged at both end sides of the stay 24. Attach the label bolt 23, which is a supporting member, to the rear tray 21.
The stay 24 is passed over so that the stay 24 is brought into contact with the iron plate portion 22 of the vehicle body located on the back side of the vehicle body, and in this state, the stay is tightened and fixed by the wing nut 28 screwed to the center bolt 26. In FIG. 5 (B), reference numeral 29 denotes a spacer that is interposed between the rear tray 21 and the speaker unit S when the speaker unit S is attached, and is a fifth spacer when the rear window (not shown) is low depending on the vehicle type. Figure (A)
This spacer may not be used as in.

[Problems to be Solved by the Invention] The conventional mounting structure for a vehicle-mounted speaker described above has the following drawbacks.

That is, as shown in FIG. 5B, when the spacer 29 is not used, the size and type of the speaker unit S,
Alternatively, the magnetic circuit section S1 may be located at a shallow position as shown in the figure due to the internal structure of the rear tray 21, and in this case, the stay 24 must be arranged close to the rear tray 21, but in general, Since the length of the label bolt 23 is constant, the label bolt 23 remains protruding much more than necessary, and there are drawbacks such as a danger and a tool hit when wiring the lower part of the rear tray.

The object of the present invention is to eliminate the above-mentioned conventional drawbacks, to easily and surely attach the speaker unit, to adjust the height position of the stay for fixing the speaker arbitrarily, and also to mount the inside of the attaching portion such as the rear tray. Another object of the present invention is to provide a mounting structure for a vehicle-mounted speaker in which unnecessary protrusions and the like do not occur on the side.

[Means for Solving the Problems] In the mounting structure for a vehicle-mounted speaker according to the present invention, when mounting the embedded-type vehicle-mounted speaker to the speaker mounting portion such as the rear tray, the support members arranged at both end sides of the stay are described above. In the mounting structure of the embedded type vehicle-mounted speaker in which the stay is passed over so as to be in contact with the rear surface side of the speaker mounting portion, and the stay and the magnetic circuit portion of the speaker unit are tightened and fixed by bolts and nuts, A block body having a stay fitting portion is arranged as a member, and the block bodies can be sequentially connected by being fitted to each other so that the height position of the stay can be adjusted by connecting the block bodies. It is composed.

[Operation] Since each block body is formed in the same shape and is fitted to each other so that they can be sequentially connected and stacked, and each block body is provided with a stay fitting portion. , The end portions of the stay are fitted to the stay fitting portions, and the block bodies are arranged on both end portions of the stay in this way. The position of the stay is determined according to the height position of the center bolt protruding from the speaker unit side. Therefore, if the block body of the first stage is low, the block bodies of the second stage and the third cross section are sequentially connected. And adjust the height.

As described above, the center bolt is inserted into the hole formed in the stay with the block bodies arranged on both ends of the stay, and the wing nut is screwed to prevent the stay from falling off. When the wing nuts are screwed in while the block bodies at both ends of the stay are positioned so as to come into contact with the back surface side of the speaker mounting portion, for example, a predetermined position on the back surface side of the iron plate portion of the vehicle body, the contact portion of the block body is contacted. Comes into contact with the rear surface side of the iron plate of the vehicle body and is further tightened to firmly fix the speaker unit.

[Embodiment] The first embodiment of the mounting structure of the in-vehicle speaker according to the present invention
Description will be made with reference to FIGS.

In the mounting structure of the in-vehicle speaker according to the present invention, when mounting the embedded type in-vehicle speaker in the speaker mounting portion of the rear tray 1, the supporting members arranged at both end sides of the stay 4 are attached to the back side of the speaker mounting portion. In the mounting structure of the embedded vehicle-mounted speaker in which the stay 4 is passed over so as to be in contact with each other, and the stay 4 and the magnetic circuit portion S1 of the speaker unit S are tightened and fixed with bolts and nuts, the stay fitting is performed as the support member. The block body 10 having the joint portion 12 is arranged, and the block bodies 10 are formed so as to be sequentially connectable by fitting with each other, and the height position of the stay is adjusted by connecting the block bodies. It is configured to obtain.

To describe a specific example of the above configuration, the connecting structure of the stay 4 and the speaker unit S is the same as the conventional structure described with reference to FIGS. 5 (A) and 5 (B), and the yoke S2 of the speaker unit S is the same. A nut 7 is fixed to the bottom surface of the center bolt 6 and a center bolt 6 is screwed into the bottom face of the stay 4, and a wing nut 8 screwed onto the head of the center bolt 6 protruding from the hole 5 of the stay 4.
It is a type that is fixed by tightening with.

A block member 10 serving as a support member is provided on both ends of the stay 4.
The block bodies 10 are formed in the same shape as shown in FIGS. 2 and 3, and a base plate-shaped contact portion 11 is formed on one end side, and the other end side is formed. The stay fitting portion 12 is formed by an "L" -shaped facing portion. Therefore, by fitting the end portions of the stay 4 into the stay fitting portions 12, the block bodies 10 are arranged on both end portions of the stay 4, respectively.
