に、比弾性率が大きい利点を有するが、蒸着により製造
するため、ウーハ等の大きなスピーカ用振動板を製造す
る場合には、−回の蒸着による製造個数が少なくなり、
効率が悪く、高価となるとともに、大量生産が困難であ
る欠点がある。Both the above-mentioned aluminum diaphragm and boron vapor-deposited diaphragm have the advantage of a large specific elastic modulus, but since they are manufactured by vapor deposition, when producing a large speaker diaphragm such as a woofer, it is necessary to deposit - times. Due to this, the number of units manufactured will decrease
The drawbacks are that it is inefficient, expensive, and difficult to mass produce.
本発明は上記従来例の欠点を除去するものであり、タン

ボロンを付着した線材を、スピーカ用振動板形状に巻回
することを特徴とするものである。The present invention eliminates the drawbacks of the above-mentioned conventional examples, and is characterized in that a wire material in which boron is attached to the outer surface of a tungsten wire by chemical vapor deposition (CVD method) or the like is wound in the shape of a speaker diaphragm. It is something to do.
以下に本発明の一実施例について第１図、第２図ととも
に説明する。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
第１図において、１は円錐台形状の金型、２はタングス

動板を製造するものである。In Fig. 1, 1 is a truncated cone-shaped mold, 2 is a wire rod with boron attached to the outer periphery of a tungsten wire, and the wire rod 2 is coated with Epoquin resin, etc. The cone-shaped diaphragm shown in FIG. 2 is manufactured by winding and fixing the wire material 2 around the outer peripheral surface of the wire rod 1, and then removing the fixed wire material 2 from the mold 1.
第３図は本発明の他の実施例を示している。FIG. 3 shows another embodiment of the invention.
本実施例はハニカム材等からなるコーン形状の芯材３の
内周面、外周面に前述の線材２，２′ を巻回して固着
したものである。In this embodiment, the aforementioned wire rods 2, 2' are wound and fixed around the inner and outer peripheral surfaces of a cone-shaped core material 3 made of honeycomb material or the like.
なお第３図に示す実施例において、あらかじめ、前述の
第１の実施例と同様にコーン形状に形成された線材を芯
材３の内周面、外周面に接着してもよいものである。In the embodiment shown in FIG. 3, cone-shaped wire rods may be bonded to the inner and outer circumferential surfaces of the core material 3 in advance, as in the first embodiment.
以上のように、本発明は、線材を巻回してスピーカ用振
動板としているため、従来の蒸着方法を用いるものに比
較して、特にウーハ等の大形のスピーカ用振動板を大量
に製造でき、安価なスピーカ用振動板を提供できる利点
を有するものである。As described above, in the present invention, since the speaker diaphragm is made by winding a wire, it is possible to manufacture large speaker diaphragms such as woofers in large quantities compared to those using conventional vapor deposition methods. This has the advantage of providing an inexpensive speaker diaphragm.
また本発明ではボロンを付着した線材を用いるため比弾
性率が高くなる利点を有するものである。Furthermore, since the present invention uses a wire rod to which boron is attached, it has the advantage that the specific modulus of elasticity is increased.
