【考案の詳細な説明】
この考案は、スピーカのケースまたはホーンに
支持具を取付ける構造に関する。[Detailed Description of the Invention] This invention relates to a structure for attaching a support to a speaker case or horn.
従来、合成樹脂製のスピーカケースまたはホー

いう難点があつた。 Previously, a metal U-shaped support was attached to a synthetic resin speaker case or horn using nuts and bolts, but since the case or horn is made of resin, it is not enough to support a heavy speaker. It is difficult to obtain sufficient mounting strength, and
The problem was that if it was tightened too tightly, it could cause cracks.

れている。 This invention was made in order to solve the above-mentioned conventional problems, and will be explained below based on the embodiment shown in the drawings.As shown in FIG. A unit cover 3 and a U-shaped support 4 are attached to the unit cover 3 and the U-shaped support 4. FIG. 2 is an enlarged partial cross-sectional view of the mounting part of the support 4, showing a through hole 6 for the bolt 5 in the case 2 and two threads located apart from the through hole 6 according to the size of the head 7 of the bolt 5. A first bolt 5 is provided with ribs 8 parallel to each other, and a bag-shaped female threaded portion 9 is formed in the axial direction from the head 7. The first bolt 5 is fixed in a through hole 6 with a nut 10, and the female threaded portion of the bolt 5 A second bolt 11 passing through a mounting hole 12 of the support 4 is coupled to the support 9 . The head 7 of the first bolt 5 has an annular groove 14 on the side of the shaft 13, and a waterproof ring packing 15 is inserted into the space between the case 2 and the rib 8. The rib 8 is provided so as to hit the head 7 of the first bolt 5 and have a height that does not protrude beyond the head 7, and is also provided so as to be parallel to the direction in which the mold is removed when the case 2 is molded from synthetic resin. There is.
このように構成されていて、第１のボルト５と
ナツト１０をケース２の貫通孔６に固定すると、
支持具４の取付けは第２のボルト１１によつて行

めとして働くとともに、金型の抜き方向と平行に
設けられているから、容易に一体成形される。 With this structure, when the first bolt 5 and nut 10 are fixed in the through hole 6 of the case 2,
The support 4 is attached using the second bolt 11, but since no force is applied directly to the case 2 at this time, even if the bolt 11 is tightened too strongly, it will not crack or become heavy. Sufficient strength can also be obtained for the speaker, and the support 4 can be attached strongly and reliably. Further, since the rib 8 acts as a stopper for the bolt 5 and is provided parallel to the direction in which the mold is removed, it can be easily integrally molded.
上述のように、この考案によれば、合成樹脂製

とができるという実用上優れた効果を奏する。 As mentioned above, according to this invention, even if the speaker horn or speaker case is made of synthetic resin,
This provides excellent practical effects in that it is possible to obtain sufficient mounting strength of the support to support the entire heavy speaker, and to prevent damage caused by over-tightening of mounting bolts.
