に限界を持つことになる。[Detailed Description of the Invention] The present invention relates to a damper mounting structure for an electrodynamic speaker. A conventional damper of this type has its outer periphery fixed to the speaker frame with an adhesive. However, this planar fixing means using an adhesive layer may be partially peeled off due to vibrations during operation of the diaphragm, or may deteriorate over a long period of time due to thermal deterioration of the adhesive due to the heat of the frame. become weak. Therefore, a simple bonding method has a limit in terms of strength.

接着の限界を改善しようとするものである。 The purpose of this invention is to drill a plurality of mounting holes for adhesive expansion at predetermined intervals on the outer periphery of the damper, and to form a rivet-like structure with the adhesive in the mounting holes. , which attempts to improve the limitations of the conventional planar bonding described above.
以下、本考案を図面に示す一実施例にもとづき
具体的に説明する。 Hereinafter, the present invention will be explained in detail based on an embodiment shown in the drawings.

て等間隔に穿設してある。 As shown in FIG. 1, the damper 1 for an electrodynamic speaker of the present invention is constructed by drilling a plurality of mounting holes 4 at predetermined intervals in the outer peripheral edge 3 of an annular damper body 2. . Here, the damper body 2 is made of cloth material impregnated with paint that serves as a filler and damping material, or a synthetic resin sheet, etc.
It is constructed by forming annular waves to provide high compliance. In addition, the plurality of mounting holes 4 are
These are for forming adhesive bulges during bonding, and are drilled at equal intervals, for example, at intervals of about 1 cm.

Similarly, it is fixed with adhesive 8. At this time, in addition to applying the adhesive 8 of the outer peripheral edge 3 to the joint surface with the frame 7,
Apply a little more to the mounting hole 4. In this way, the adhesive 8 at the mounting hole 4 is applied to the outer peripheral edge 4 of the damper body 2, as shown in FIG.

It flows out from the attachment hole 4 to the upper surface and bulges out in the shape of a rivet. Therefore, the outer peripheral edge 3 of the damper main body 2 is securely fixed to the frame 7 by the planar adhesive action and riveting action. Note that the adhesive 8 is preferably selected to have a certain degree of hardness after being applied.

る。 As described above, according to the present invention, not only is the outer peripheral edge of the damper body fixed to the frame by the layered adhesive interposed between the damper body and the frame, but the adhesive also enters the mounting hole and hardens while maintaining the rivet shape. Since the damper body can be attached to the frame by fitting together and riveting, the damper is securely fixed and bonded, and the adhesive strength of conventional adhesives deteriorates over time. However, even if the adhesive deteriorates due to heat, the attachment is maintained reliably by the fit of the rivet-like parts.
