【考案の詳細な説明】
本考案は軽量で高比弾性率（高剛性）を有するスピーカ
用振動板を提供するものである。[Detailed Description of the Invention] The present invention provides a speaker diaphragm that is lightweight and has a high specific modulus (high rigidity).
従来、スピーカ用振動板としては、紙コーン、金属、各
種発泡体、ハニカム材などが各々目的に応じて使用され
ているが、上記振動板の必要特性をすべて満足させるも
のは無くそれぞれ一長一短がある。Conventionally, paper cones, metals, various foams, honeycomb materials, etc. have been used as diaphragms for speakers, depending on the purpose, but none satisfies all of the necessary characteristics of the diaphragm, and each has its advantages and disadvantages. .
本考案は軽量で曲げ剛性にすぐれ、しかも安価に製造す
ることが可能なスピーカ用振動板を提供するものである
。The present invention provides a speaker diaphragm that is lightweight, has excellent bending rigidity, and can be manufactured at low cost.
従来軽量で高剛性を得るためハニカム材を用いたスピー
カ用振動板が提案されているが加工成形に難点がありし
かも重量が大なる欠点を有していた。Hitherto, a speaker diaphragm using a honeycomb material has been proposed in order to be lightweight and have high rigidity, but it has the disadvantage of being difficult to process and mold and being heavy.
本考案は上記従来の欠点を除去するものであり、第１図
に示すように、長尺の板状体をジグザグ状に折曲してな

状に展開し、骨格部材１の両端面を接着する。The present invention eliminates the above-mentioned drawbacks of the conventional method.As shown in FIG. 1, a skeleton member 1 made by bending a long plate-like body in a zigzag shape is used as shown in FIG. - It is expanded into an annular shape so that the side part side (A side) is the inner circumferential edge and the other side part side (B side) is the outer circumferential edge, and both end surfaces of the skeleton member 1 are adhered.
このように環状に形成された骨格部材１の両面に剛性の

１５ｍｍの繊維強化プラスチツクシー）−２，２’を接
着したものである。For the skeleton member 1 of the above embodiment, a special paper with a density of 0.5 and a thickness of 0.3 made by treating kraft pulp with a resin was used, and it was molded into a zigzag shape as shown in FIG. 1 by hot and humid molding. This skeleton member 1 is expanded into an annular shape and has a thickness of Q on both sides.
15mm fiber-reinforced plastic (2,2') is glued together.
ここで、樹脂処理した紙としては、たとえばクラフト紙
にラテックスを含浸したり、クラフト紙に酢酸ビニルエ
マルジョンを含浸したり、クラフト紙にシリコンゴムを
含浸した公知のものが利用できる。Here, as the resin-treated paper, for example, known paper such as kraft paper impregnated with latex, kraft paper impregnated with vinyl acetate emulsion, or kraft paper impregnated with silicone rubber can be used.
第４図は本考案の他の実施例を示しており、環状に展開
してなる骨格部材１の片面を平面にし、第５図に示すよ
うに、その両面にシー） ２．２’を接着して完成する
ものである。Fig. 4 shows another embodiment of the present invention, in which one side of the skeleton member 1 developed in an annular shape is made flat, and as shown in Fig. 5, sheets 2.2' are bonded to both sides. It is completed by doing so.
なお振動板の曲げ剛性を高めるために第６図に示すよう
にコニカル形状にすることも可能である。Note that in order to increase the bending rigidity of the diaphragm, it is also possible to form it into a conical shape as shown in FIG.
また、上記実施例では、骨格部材１の両面にシート２．
２’を接着しているが、骨格部材１の片面のみに接着し
てもよいものである。Further, in the above embodiment, sheets 2.
2' is bonded, but it may be bonded to only one side of the skeleton member 1.
以上、詳述したように本考案によれば、板状体を折曲し
てジグザグ形状とし、−側部側が内周面、他側部側が外
周面となるように環状に展開した骨格部材を使用してい
るため、従来の終コーン紙に比較して同一重量における
曲げ剛性が大となり、この振動板を用いたスピーカは再
生特性における高域限界を拡大することができる。As described in detail above, according to the present invention, a skeletal member is formed by bending a plate-like body into a zigzag shape and expanding it into an annular shape so that the inner circumferential surface is on the one side and the outer circumferential surface is on the other side. Because it is used, the bending rigidity for the same weight is greater than that of conventional final cone paper, and a speaker using this diaphragm can expand the high range limit of reproduction characteristics.
また、骨格部材の素材としての板状体には樹脂処理した
紙を使用しているため、軽量化でき、しかも含浸する樹
脂の選択により内部損失を自由に設定することができる
ため、高域におけるピークディップを低く抑えることも
できる利点を有するものである。In addition, since resin-treated paper is used for the plate-shaped body as the material for the frame members, it is lightweight, and internal loss can be freely set by selecting the resin to be impregnated. It also has the advantage of being able to suppress peak dips to a low level.
