本発明は電気音響変換器に用いるボイスコイル用ボビン
の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of manufacturing a voice coil bobbin used in an electroacoustic transducer.

精度を得ることは困難であった。(Prior art and its problems) A voice coil bobbin (hereinafter simply referred to as a bobbin) used in an electroacoustic transducer is lightweight, rigid, heat resistant,
It requires excellent water resistance (waterproof, moisture-proof), and a high degree of dimensional accuracy is also required to vibrate within a narrow gap. A bobbin that is weak in heat and water resistance will be deformed by heat and moisture, and may come into contact with gaps in the magnetic circuit, or even damage the coil wound on the bobbin. The same applies to dimensional accuracy. With conventional bobbins mainly made of kraft paper or spiral paper,
These properties were not fully satisfied, and a lightweight and rigid bobbin could not be obtained. Furthermore, bobbins made primarily of paper have seams when molded into a bobbin shape, making it difficult to obtain perfect circular dimensions.
（問題点を解決するための手段）
本発明は上記の問題点に鑑み提案されたもので、その目

製造方法を提供することにある。(Means for Solving the Problems) The present invention was proposed in view of the above problems, and aims to be lightweight, rigid, and heat resistant.
An object of the present invention is to provide a method for manufacturing a voice coil bobbin that has excellent water resistance and high dimensional accuracy.
すなわち、本発明は上記目的を達成するために捲き治具

要旨とするものである。That is, in order to achieve the above object, the present invention provides a method for manufacturing a voice coil bobbin, which is characterized in that the string-like body is wound spirally around a winding jig and then the string-like body is fixed. It is something.
（実施例） 以下、本発明の一実施例を図を用いて説明する。(Example) An embodiment of the present invention will be described below with reference to the drawings.
まず、第１図に示すように、捲き治具１を準備し、捲き

完成する。First, as shown in FIG. 1, a winding jig 1 is prepared, and the string-like body 2 is wound around the winding jig 1 in a spiral manner. String body 2
Wrapping is done so that adjacent string-like bodies 2 are in close contact with each other. For winding, match the width to the bobbin dimensions. Next, the surfaces of the tightly wound string-like bodies 2 are bonded and solidified between adjacent string-like bodies 2 and on the surface using an adhesive. By pulling out the bond winding jig that has been bonded and solidified, the bobbin 3 shown in FIG. 2 is completed.

アミド等の有機繊維が適用できる。As the string-like body used for the bobbin, inorganic fibers such as glass fiber, alumina mM, carbon fiber, etc., or organic fibers such as aromatic polyamide can be used.
なお、前記実施例では捲き付は幅をボビン寸法に合わせ
るとしたが、複数のボビン寸法に合わせて捲き付は接着
固化した債ボビン寸法に切断する方法もある。In the above embodiment, the width of the winding is adjusted to match the bobbin size, but there is also a method of cutting the winding into bond bobbin sizes that are bonded and solidified in accordance with a plurality of bobbin sizes.

である。(Effects of the Invention) As explained above, according to the present invention, by winding the string-like body spirally around the winding jig and then fixing the string-like body, the winding jig is lightweight, rigid, and heat-resistant. It is possible to manufacture a bobbin for a voice coil used in an electroacoustic transducer that has good crushability, water resistance, and a high degree of dimensional accuracy. Also,
Highly heat resistant voice coil bobbins are useful for high input applications.
