Description

[Detailed description of the invention] This invention is a decorative flange for the speaker that is concealed in the periphery of the speaker frame to make it look aesthetically beautiful in the front type installation method in which the periphery of the speaker frame is attached to the front of the full board. Regarding the improvement of

A conventional decorative flange for a speaker of this kind is made of resin, and as shown in FIG.
It is composed of an inner peripheral part B, a top plate part C, and bosses D protruding from the back surface of the top plate part C at regular intervals.
By tightening the screw E inserted into the full plate F, together with the outer periphery H of the speaker frame G,
It was attached to the front of Batsuful board F. and,
The outer periphery A of the decorative flange is lifted from the full plate F in order to escape from abnormal noise caused by the driving force of the speaker I.

However, when installing the decorative flange, the screw holes of the boss D, the screw holes formed on the outer periphery of the speaker frame, and the screw holes of the buttful plate F do not necessarily match, so tighten the screws E. When this happens, the boss D tilts, which deforms the decorative flange, resulting in an unsightly design.
In addition, due to uneven deformation, a portion of the outer circumferential portion A of the decorative flange comes into contact with the buttful plate F, which causes abnormal noise.

Therefore, the present invention is an attempt to solve the above-mentioned drawbacks, and aims to prevent deformation and abnormal noise by providing a protrusion that comes into contact with the buttful plate at the lower end of the outer periphery. To provide decorative flanges for speakers.

Hereinafter, the present invention will be explained based on the embodiments shown in the drawings. Fig. 2 is a half-cut sectional view of a speaker using a decorative flange according to the present invention, Fig. 3 is a back view showing a part of the flange, and Fig. 4 Figures A, B, and C are side views of different embodiments showing essential parts of the same flange.

In the above drawings, reference numeral 1 denotes a full plate, 2 a speaker, 3 a speaker frame, and an outer peripheral portion 4 of the frame 3 is formed with an insertion hole 4a for a mounting screw 5. 6 is a magnetic circuit, 7 is a voice coil, 8 is a diaphragm, 9 is a damper, and 10 is an edge.

Reference numeral 11 denotes a flange main body that hides the outer peripheral part 4 of the speaker frame 3. The flange main body 11 projects from the outer peripheral part 12, the top plate part 13, and the back surface of the top plate part 13, and is connected to the mounting screw 5. It is composed of a boss 14 having an insertion hole 14a and an inner peripheral portion 15, which are integrally formed of resin.
The lower end 12a of the outer peripheral portion 12 of the flange main body 11 is set to be located slightly above the lower end of the boss 14. Further, the lower end 12a of the outer circumferential portion 12 is provided with a plurality of protrusions 16 that come into contact with the front surface of the buff-full plate 1.As shown in FIG. 13 to the left and right from the center of the insertion hole 14a, respectively.
be installed at a separate location. Also, the height of the protrusion 16 is the height of the boss 14 + the outer circumference 4 of the speaker frame 3.
The bottom edge is set to be at the thickness of . Further, the shape of the protrusion 16 may be any shape such as a rectangular shape, a semicircular shape, an inverted triangular shape, etc. as shown by A, B, and C in FIG. 4. Note that the protrusion 16 is formed integrally with the outer peripheral portion 12.

Next, the assembly of the above embodiment will be explained.
First, place the speaker frame 3 on the front of the full board 1.
The outer circumferential portion 4 of the baffle plate 1 is brought into contact with the outer circumferential portion 4, and the insertion hole 4a of the outer circumferential portion 4 is aligned with a screw hole (not shown) formed in the baffle plate 1.

Next, when the flange main body 11 is placed on the outer circumference 4 of the speaker frame 3 and the insertion hole 14a of the boss 14 is aligned with the insertion hole 4a of the outer circumference 4, the lower end of the protrusion 16 becomes flat. It comes into contact with the front surface of plate 1. Therefore, by inserting the mounting screws 5 into the insertion holes 14a, 4a between the boss 14 and the outer circumference 4 of the speaker frame 3, screwing them into the screw holes of the buttful plate 1, and tightening them, the height of the boss 14 + the outer circumference The flange main body 11 is fixed to the baffle plate 1 together with the speaker frame 3 without being deformed by the protrusion 16 having a thickness of 4 mm and whose tip is located on the front surface of the buff full plate 1.

As described above, in the present invention, the lower end 12a of the outer peripheral part 12 forming the flange main body 11 is spaced apart from the front surface of the buff-full plate 1 by a fixed distance, and the outer peripheral part 1
At the lower end 12a of 2, protrusions 16 are provided near both sides of the boss 14, which has the insertion hole 14a for the mounting screw 5.
6 prevents the deformation of the flange main body 11 that occurs when the mounting screw 5 inserted into the insertion hole 14a of the boss 14 is tightened to the buff-full plate 1, and the lower end 12a of the outer peripheral portion 12 due to the deformation
It is possible to prevent abnormal noises caused by contact with the Further, since the lower end 12a of the outer circumferential portion 12 is spaced apart from the buttful plate 1 except for the protrusion 16, no abnormal noise is generated.
