【考案の詳細な説明】
本考案は、ダストキヤツプの接着を容易、正確
に、かつ、強固にするスピーカー用振動板に関す
る。[Detailed Description of the Invention] The present invention relates to a diaphragm for a speaker that allows easy, accurate, and strong adhesion of a dust cap.
スピーカ用振動板には、紙製、金属製、合成樹
脂製などがあるが、ダストキヤツプを振動板の軸
中心に接着することは困難であり、従来より、ダ
ストキヤツプの接着を容易、正確に接着する構造
が種々提案されている。 Speaker diaphragms are made of paper, metal, synthetic resin, etc., but it is difficult to adhere the dust cap to the center of the axis of the diaphragm. Various bonding structures have been proposed.
第１図のものは、振動板３の中腹部に凸状のコ
ルゲーシヨン２を形成して係止部とし、ダストキ
ヤツプ１の外縁を上記コルゲーシヨン２の内側ま
たは外側に嵌入し、その接合部を接着剤で固着す
る構造である。 In the case shown in Fig. 1, a convex corrugation 2 is formed on the middle part of the diaphragm 3 as a locking part, the outer edge of the dust cap 1 is fitted inside or outside of the corrugation 2, and the joint part is glued. It has a structure that is fixed with adhesive.
第２図に示すものは、凸状のコルゲーシヨン２
の代わりに凹状のコルゲーシヨン２１を形成して
係止部とし、また、第３図に示すものは、凸状の
コルゲーシヨン２の代わりに複数個の凸状部２２
を形成して係止部としたものである。 The one shown in Figure 2 is a convex corrugation 2.
Instead, a concave corrugation 21 is formed as a locking part, and the one shown in FIG.
is formed to serve as a locking portion.
このような構造は、凸状、凹状のコルゲーシヨ
ン２，２１または複数個の凸状部２２によつてダ
ストキヤツプ１の位置決めが正確、容易になるの
で、タストキヤツプ１を振動板３に同心的に固着
することができ、また、振動板３全体の軸方向の
バランスが得られやすいので、振動板３の偏心振
動による歪音発生を防止できる特徴がある。 With this structure, the dust cap 1 can be accurately and easily positioned by the convex and concave corrugations 2 and 21 or the plurality of convex parts 22, so that the dust cap 1 can be fixed concentrically to the diaphragm 3. Moreover, since the axial balance of the entire diaphragm 3 can be easily obtained, it is possible to prevent the occurrence of distorted noise due to eccentric vibration of the diaphragm 3.
しかしながら、ダストキヤツプ１の固着構造
は、その外縁を上記凸状、凹状のコルゲーシヨン
２，２１または複数個の凸状部２２の内側または
外側に嵌入し、その接合部を接着剤で接着する構
造であるから、ダストキヤツプ１接合部の接着強
度が不足し、接着剥がれが発生するおそれがあ
る。 However, the fixing structure of the dust cap 1 is such that its outer edge is fitted inside or outside of the convex or concave corrugations 2, 21 or the plurality of convex portions 22, and the joints are bonded with adhesive. Therefore, there is a possibility that the adhesive strength of the joint part of the dust cap 1 is insufficient and the adhesive peels off.
本考案はこのような従来欠点を改良したもの
で、第４図において説明する。 The present invention improves on such conventional drawbacks, and will be explained with reference to FIG.
１１はダストキヤツプで、外縁に複数個の凸起
５が形成されている。 A dust cap 11 has a plurality of protrusions 5 formed on its outer edge.
３は振動板で、その中腹部には等高線上に上記
ダストキヤツプ１１の複数個の凸起５と同数であ
つて、この凸起５が挿入される孔４が形成されて
いる。 Reference numeral 3 denotes a diaphragm, and holes 4, which are the same in number as the plurality of protrusions 5 of the dust cap 11, and into which the protrusions 5 are inserted, are formed on the contour line in the midsection of the diaphragm.
そして、この振動板３の孔４に上記ダストキヤ
ツプ１１の凸起５をそれぞれに挿入して係止し、
接着して固着する。 Then, the protrusions 5 of the dust cap 11 are inserted and locked into the holes 4 of the diaphragm 3, respectively, and
Glue and stick.
以上のように、本考案は、振動板３の孔４とダ
ストキヤツプ１１の凸起５との挿入、係止構造が
ダストキヤツプ１１の位置決め効果を現出して、
ダストキヤツプ１１の接着がより容易、正確にな

強度が向上し、接着剥がれのおそれがなくなる効
果がある。 As described above, in the present invention, the insertion and locking structure between the hole 4 of the diaphragm 3 and the protrusion 5 of the dust cap 11 produces the positioning effect of the dust cap 11.
This not only makes adhering the dust cap 11 easier and more accurate, but also improves the adhesion strength of the joint of the dust cap 11, eliminating the risk of adhesive peeling.
