DETAILED DESCRIPTION OF THE INVENTION This invention relates to an arrowhead for mounting a speaker cone. Traditionally, dynamic panel dynamic, speakers and electromagnetic 1llO magnetic. In the case of attaching the outer peripheral edge of cone paper to a speaker frame in a cone type speaker such as a speaker, paper that doubles as a seat plate 1 at the time of mounting the speaker, leather 2 synthetic resin An arrow of is used. That is, the outer peripheral edge of the cone paper is edged with an arrow and attached to the outer rim of the speaker frame with an adhesive. However, the conventional arrow paper was flat on both the front and back sides (l · When bonding the arrow paper to the inner surface of the outer ring ridge of the frame with an adhesive after bonding the outer edge of the outer edge of the cone paper to the inner surface of the outer ring ridge of the frame Fleeing outward from the adhesive layer between a part of the adhesive or the back of the arrow paper and the inner surface of the outer edge of the cone and the paper border of the cone paper, and protruding to the outside value of both side edges of the arrow This extruded and solidified adhesive causes irregular and complex vibrations to the corn paper (in the case of arrows or paper it is not necessary to absorb the butterfly adhesive). There is a little bit of eating out. B) to produce sounds other than the original sound, to change the frequency characteristic, that is, to change the acoustic energy and the directivity according to the frequency of the supplied current, to significantly degrade the sound quality and to adversely affect the reproduction of the bass; There was a drawback of not being able to make a deep sound and reducing the output. In addition, there is a defect that the 12-05-2019 1 adhesive effect is inferior 11S because the adhesive sticks out at the time of contacting with the sheet. Therefore, the present invention provides an arrow as described below to solve the abovementioned conventional drawbacks. .Lambda. 'The arrow paper for mounting cone paper of the speaker according to the present invention will be specifically described with reference to the drawings. L is an arrow of an appropriate size and shape suitable for the outer ring portion of the speaker frame 5, For example, it is made of an insulating material such as paper, leather 2 synthetic resin, or aluminum. Note that this arrowhead l has a quadrangular ring shape that is curved outward as shown in the drawing according to the shape of the speaker frame j, and a screw notch is provided at the four corners. In addition to those described above, there are circular ring-shaped ones having a plurality of screw cuttings as appropriate, and Fi and nonseries ring-shaped ones separated into several pieces. The groove 3 is provided on the back surface of the arrow l in this invention. It should be noted that the grooves 3 may be formed by appropriately spacing the grooves 3 in the vicinity of the cutting notches for screws as in the embodiment shown in the drawings and providing several grooves 3 on the back surface of the sheet 1 By providing a series of annular grooves 3 (if arrowhead l has an annular shape) or by providing a number of short grooves 3 etc. Is also good. · 3 · '-Since the arrow sheet of this invention is provided with the groove 3 on the reverse side-as in the case of the fence, as shown in Fig. 2, the border 7at-of the outer peripheral edge of the corn paper 7 After bonding the outer ring collar of the speaker frame j to the inner surface and then applying an adhesive to bond the arrowhead l to the upper surface of the rim 7a and the outer ring collar, the back surface 2 of the adhesive layer and arrowhead l A part of the adhesive layer between the upper edge of the rim portion 7ah and the rim portion 7ah flows and diffuses inwards and enters the groove 3 on the back surface of the arrow sheet l, as shown in FIG. The agent layer A is formed to provide a strong and firm adhesion, and the adhesive layer does not stick out to the outside of the adhesive layer, so that the corn paper 7 is formed by not sticking this adhesive out. Not give irregular complex vibrations due to distortion, etc., reduce the ratio of harmonics as simple vibrations, and make sounds other than the original sound as possible Thus, the frequency characteristics and directionality can be improved to significantly improve the sound quality, and at the same time the corn paper 7 can be made to feel well even for low sounds, and the bass part reproduction is excellent and produces a deep sound. And, there are many excellent effects such as the increase in output. It is to be noted that the dog also has an effect of becoming a dog which can remarkably lift the bonding effect by forming a strong adhesive layer A by penetration adhesion in the groove 3 of the adhesive or the arrow 1 of the adhesive. 12-05-2019 2
