DESCRIPTION JPS5748787 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view showing a sheet (material) of a conventional laminated cone, and FIG. 2 is a perspective view of the laminated cone according to the present invention. The top view which shows the sheet ¦ seat of a bonding cone, FIG. 4 is a perspective view of a bonding cone similarly.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminated cone for an audio device which is used as a lifting plate of a speaker, etc., by forming a chamfer 9 at the end of the lamination margin of the sheet as the material of the cone. It is made to be able to eliminate the level ¦ step difference in the outer peripheral part among the cones by the elongation K of the material at the time of bonding. 44 houses, ry. As for the red ume lamination corn corn in the door conventional, 1st 1. As shown in FIG. 2, when the cone paper is die-cut, a collapsible sheet 1 is formed and pasted O strips 2, 2 'at both ends thereof are pasted with an adhesive to form a conical shape 1+ jL , And has a configuration in which the neck rising portion 3 is formed by pressing the sheet inner peripheral portion (dotted line P). According to the above construction, since there is a difference in the elongation of the sheet in the direction of the cone slope of the sticking allowances 2 and 2 ', as shown in FIG. . For this reason, conventionally, it is necessary to spend a cutting process on the island in order to prevent partial deformation of the edge and to prevent inclination between the linearity and the vibration direction of the cone, and this processing is temporarily once three-dimensional That is, since it is carried out with respect to a conical shape, there is a disadvantage such as the number i s 賢 n which makes the apparatus 1 [coarse and processing costs increase]. The present invention is made to solve the above-mentioned drawbacks. That is, in the present invention, as shown in FIG. 3 and the mouth (as shown, the chamfer 4 is formed on the inner periphery and the outer peripheral edge of the bonding margin 2 of the sheet 1 or both bonding margins 2, 2 'of the sheet 1 Apply. The square cut 4 is formed into a desired shape such as forming the edge of the ridge in a circular arc shape 11-05-2019 1 or cutting it in a triangular shape as shown in the figure, but the point is that it is the largest at the time of bonding 1) 2 and 2 ' Consider the growth rate i to be much larger than the area equivalent to it. This square cut is NI bonded and laminated in the same manner as the sheet 1 pipe, and the press forms an O-neck top by the 41st! ! As shown in IIK, a step-less laminated cord / B is obtained. As described above, the present invention is obtained by chamfering the inner periphery and outer periphery 1 edge of the bonding margin of the sort which is the material of the bonding cone, so that no level difference is generated at the time of bonding and forming 4, 4. Thus, it is possible to prevent, in advance, breaking and the like in the vibration direction of the cone without subjecting to the step cutting process as in the prior art. In addition, chamfering can be easily performed by deforming a part of the entire sheet, and the cost of processing the cone can be reduced to a large size. Figure 1 of the drawing is a plan view showing a sheet (i material) of a conventional laminated cone, FIG. 2 is a perspective view of the laminated cone, FIG. The flat ik 1 figure which shows the sheet ¦ seat of the bonding cone which concerns on this invention, FIG. 4 is a perspective view of the bonding cone to the same. .
