【考案の詳細な説明】
この考案は金属を使用するスピーカ振動板の改
良に関するものである。[Detailed Description of the Invention] This invention relates to an improvement of a speaker diaphragm using metal.
従来、金属を使用した振動板は第１図、第２図
に示すものがあつた。主に金属は単板であり、そ
れにダンピングを目的としたものが付加されてい
た。 Conventionally, diaphragms using metal have been shown in FIGS. 1 and 2. Mainly the metal was a single plate, with damping added to it.
第１図及び第２図において１は金属振動板、２
はゴム系の物質、３はダンピング塗料である。 In Figures 1 and 2, 1 is a metal diaphragm, 2
is a rubber-based substance, and 3 is a damping paint.
この中で金属を使用した振動板は、他の材質に
比較して振動伝播速度が速く、薄膜にすることに
より重量も他と変わらない程度に出来ることか
ら、特に高音用として有利であつた。 Among these, diaphragms made of metal have a faster vibration propagation speed than other materials, and are particularly advantageous for high-pitched sounds because they can be made into thin films with the same weight as other diaphragms.
しかし、金属固有の音がつきまとうため、これ
を打ち消すためにダンピングをしなければなら
ず、ダンピング塗料やゴム系物質を貼付するため
振動板として重量が増したり、接着剤による貼付
がはがれる欠点があつた。 However, due to the sound inherent to metals, damping must be applied to cancel this out.There are also drawbacks such as the weight of the diaphragm increasing due to the application of damping paint or rubber-based materials, and the fact that the adhesive may peel off. Ta.
この考案は上記の欠点を除去するためのもの
で、金属の有利な点を持ちながら、金属固有の音
を打ち消すことが出来る振動板、並びに耐熱性、
耐久性および材質の均一性の優れた振動板を提供
することを目的とする。 This idea was created to eliminate the above-mentioned drawbacks, and while having the advantages of metal, it also has a diaphragm that can cancel out the sound inherent in metal, as well as heat resistance,
The purpose of the present invention is to provide a diaphragm with excellent durability and material uniformity.
以下、この考案の一実施例を図について説明す
る。 An embodiment of this invention will be described below with reference to the drawings.
第３図において、４はガラス繊維糸を織つた布
の表面にAl（アルミ）、Ti（チタン）、Ｂ（ほう素）、
Be（ベリリウム）等の金属を一体に結着して形成
された振動板である。 In Figure 3, 4 shows Al (aluminum), Ti (titanium), B (boron) on the surface of the cloth woven with glass fiber threads.
A diaphragm made by bonding metals such as Be (beryllium) together.
前記振動板４を形成する場合、Al（アルミ）な
どガラス繊維布より融点の低い金属においては、
ガラス繊維布の表面に蒸着或いは金属を溶かしこ
れを溶射するなどの手段により一体に形成する。
又融点の比較的高いTi（チタン）、Ｂ（ほう素）、
Be（ベリリウム）等の金属においては、薄膜シー
ト状（30〜50ミクロン）の金属板となし、これを
ガラス繊維布と積層して両者を溶着などにより一
体形成し、振動板４の全体厚さをほゞ70〜100ミ
クロン程度のものに仕上げたものである。 When forming the diaphragm 4, a metal with a melting point lower than that of glass fiber cloth, such as Al (aluminum), is used.
It is integrally formed on the surface of the glass fiber cloth by means of vapor deposition or thermal spraying of melted metal.
Also, Ti (titanium), B (boron), which have relatively high melting points,
For metals such as Be (beryllium), the metal plate is made into a thin film sheet (30 to 50 microns), and this is laminated with glass fiber cloth and the two are integrally formed by welding, etc., so that the overall thickness of the diaphragm 4 It is finished to approximately 70 to 100 microns.
これにより、振動伝播速度は表面の金属を伝播
して行き、従来の金属単板より劣ることがなく、
金属固有の音は織られたガラス繊維布の中でダン
ピングされる。すなわち、ガラス繊維布を用いて
いることから、交錯した多数のガラス繊維間の摩
擦を利用して損失係数を良好なものとしたうえ、
さらに一体化された金属層により弾性率を向上さ
せることができるのである。 As a result, the vibration propagation speed propagates through the surface metal, and is no worse than a conventional metal veneer.
The inherent sound of the metal is damped within the woven glass fiber cloth. In other words, since glass fiber cloth is used, the friction between the many intertwined glass fibers is utilized to achieve a good loss coefficient.
Moreover, the integrated metal layer can improve the elastic modulus.
以上のように、この考案によれば、従来のよう
に特別なダンピングを必要としなくなるので、作
業の簡素化が期待できる。 As described above, according to this invention, there is no need for special damping as in the prior art, so it can be expected that the work will be simplified.
又、この考案における振動板には、ガラス繊維
布を用いたので成形およびその作業性が容易であ

結着して形成したので、ガラス繊維布の持つ特有
の耐熱性、及び高い引張力の優れた性能を加味し

機質のものであり、他の有機質の材質を使用した
振動板に比べ、振動板全体を均一に製作すること
が可能であり、且つ又耐久性並びに音質の透明性
の優れた振動板を提供できる効果を奏することが
できる。さらに、ガラス繊維を用いたため繊維間
の摩擦を利用して損失係数を良好なものとし、か
つ一体化された金属層により弾性率をも向上させ
ることができるものである。 In addition, since the diaphragm in this invention uses glass fiber cloth, molding and workability are easy, and since it is formed by integrally bonding metal such as Al to glass fiber cloth, glass fiber cloth can be used. In addition to providing a diaphragm that takes into account the unique heat resistance and excellent performance of high tensile force, the glass fiber cloth is inorganic, and compared to diaphragms using other organic materials, the diaphragm It is possible to manufacture the whole diaphragm uniformly, and it is also possible to provide a diaphragm with excellent durability and transparency of sound quality. Furthermore, since glass fibers are used, the loss coefficient can be improved by utilizing the friction between the fibers, and the elastic modulus can also be improved by the integrated metal layer.
