Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching a speaker unit to a buttful plate.

As is well known, in order to attach a speaker unit to a speaker mounting hole formed in a baffle board, it is common to tighten it with wood screws 22 as shown in FIG. Since they are arranged at predetermined intervals on the circumference, the mounting strength may be partially reduced, and there is a risk that resonance may occur in the speaker frame 21.

The purpose of this invention is to solve the above-mentioned drawbacks of the conventional speaker unit, and to provide a mounting structure for a speaker unit that is not only easy to install, but also allows the speaker frame and bumper plate to be firmly fixed, and does not cause resonance etc. Our goal is to provide the following.

Hereinafter, embodiments of the present invention will be described based on FIGS. 2 to 5.

In the figure, A is a speaker unit that is attached to the speaker mounting hole 5 formed in the buffle board 2, and 3 is a fastening member for fastening the speaker frame 1 and the buffle board 2. , is ring-shaped and has a wedge-shaped cross section. A tapered outer edge 4 is formed on the outer surface of the speaker frame 1 so as to correspond to the upper surface fastening member 3, and an outer edge 4 corresponding to the outer edge 4 is formed on the inner periphery of the opening of the speaker mounting hole 5. A tapered inner edge 6 is formed. The fastening member 3 is fitted between the outer edge 4 and the inner edge 6, and therefore, the outer circumferential surface 7 of the fastening member 3 is attached to the inner edge 6, and
The inner circumferential surface 8 is in close contact with the outer edge 4.

The tightening means 9 for tightening the tightening member 3 is configured to tighten bolts at positions dividing the ring-shaped tightening member, and is provided in bolt holes provided in the flange 11 of the speaker frame 1. 12 into the screw hole 13 provided in the tightening member 3, and as the bolt 10 is tightened, the tightening member 3 connects to the outer edge 4 of the speaker frame 1 and the speaker mounting hole 5. The speaker frame 1 is press-fitted between the inner edge 6 of the speaker frame 1 and the buff-full plate 2, so that the speaker frame 1 and the buff-full plate 2 are firmly fixed. Reference numeral 14 is a drop-off prevention member formed by bending the tip into an "L" shape, and is attached to the inner surface of the rounded plate at the lip of the speaker mounting hole 5 with a screw 15, so that it cannot be disassembled or assembled. This is designed to prevent the fastening member 3 and the like from falling into the enclosure. In the example shown in FIG. 2, this fall prevention member 14 is designed to prevent the fastening member 3 from falling.

Note that the mounting position of the fastening member 3 is not limited to the above embodiment; for example, as shown in FIG. The frame 1 may be fitted from the surface side of the frame 1. In this case, the flange 11 is provided inside the frame 1 and the bolt 10 is screwed into the flange 11. In this case, the fall prevention member 14 acts to prevent the speaker unit A from falling. Further, as shown in FIG. 5, the first fastening member 3, which is attached from the front side of the buttful plate 2, and the second fastening member 3', which is attached from the back side of the buttful plate 2, are used to tighten the bolts. 10 may be used to fix the full board 2 and the speaker frame 1.

As described above, the fastening member 3 allows the buff-full plate 2 to be firmly fixed to the speaker frame 1 without any gaps, and resonance of the speaker frame 1 can also be prevented. Furthermore, mounting of the speaker frame 1 is extremely easy, and manufacturing man-hours can also be reduced.

According to the mounting structure of the speaker unit according to the present invention, a ring-shaped fastening member with a wedge-shaped cross section is inserted between the outer edge of the speaker frame and the inner peripheral edge of the speaker mounting hole, and the fastening member is tightened. By tightening the fastening member with screws or other fastening means at the positions where the wearable member is divided, the speaker unit is fixed by the wedge action of the fastening member, so that the speaker frame and the buttful plate can be fixed. It can be fixed uniformly and firmly, so even if the tightening means is provided at a position that divides the frequency of the tightening member, the whole can be fixed, and resonance of the speaker frame can be appropriately prevented. In addition, a falling prevention member is attached to the inner surface of the round board at the lip of the speaker mounting hole, so parts will not fall when assembling or disassembling the speaker system, making assembly and disassembly easy. .

Furthermore, since the baffle plate does not require any special processing, it has excellent features such as not causing a large cost increase in implementation.
