産業上の利用分野
本発明は音響用機器に用いられるコンデンサに関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a capacitor used in audio equipment.
従来の技術
音響機器に用いられるコンデンサは、その機器の特徴か

それ以外の回路では、損失が少なく、周波数特性のよい
フィルムコンデンサが多く用いられている。そのフィル

ポリスチロール等が主に使われていた。Conventional technology Due to the characteristics of the equipment, film capacitors with low loss and good frequency characteristics are generally used in other circuits, excluding circuits that do not have a particularly large effect on sound quality. ing. Among these film capacitors, materials such as polypropylene and polystyrene, which have low loss, were mainly used.
さらに、音質の向上のために、コンデンサの電極には銅
もしくは錫箔が用いられていた。Furthermore, to improve sound quality, copper or tin foil was used for the electrodes of the capacitor.
発明が解決しようとする課題
しかしながら、この従来のコンデンサでは、誘電体にポ
リプロピレンやポリスチロールが用いられているために
、耐熱性に乏しく、プリント配線基板への半田付けの際
の熱に弱く、他の部品に比べて細心の注意が必要であり
、その解消が音響機器製造上の大きな課題となっていた
。Problems to be Solved by the Invention However, since these conventional capacitors use polypropylene or polystyrene as the dielectric, they have poor heat resistance, are susceptible to heat when soldering to printed wiring boards, and are susceptible to other problems. This requires greater care than other parts, and resolving this issue has been a major challenge in the production of audio equipment.
また、それらは実使用時の耐熱温度が低く、特に８５℃
以上の連続使用が可能な部品の必要な音響機器では、そ
れを使用する範囲を大幅に制限するものであった。In addition, they have a low heat resistance temperature during actual use, especially 85℃.
Audio equipment that requires parts that can be used continuously as described above greatly limits the range in which they can be used.
さらに、特に誘電体にポリプロピレンフィルムを用い、
電極に銅箔を用いたコンデンサの場合においては、銅に
よってポリプロピレンが劣化する（一般には調書という
）ので、その信頼性に難点がある。近年では、劣化防止
膜を施した銅箔が用いられているものの、大幅なコスト
高となる上に、薄い劣化防止膜では製造工程での熱処理
、高ＱＨ度下での実使用に耐えられず、信頼性が実使用
上十分であるとは言えなかった。Furthermore, using polypropylene film as the dielectric material,
In the case of capacitors that use copper foil for the electrodes, the polypropylene deteriorates due to the copper (generally referred to as a record), so there is a problem with its reliability. In recent years, copper foil coated with a deterioration prevention film has been used, but the cost is significantly higher, and the thin deterioration prevention film cannot withstand heat treatment during the manufacturing process or actual use under high QH conditions. However, it could not be said that the reliability was sufficient for practical use.
ポリスチロールを誘電体に用いた場合においては、さら
に耐薬品性に欠点があり、プリント配線基板への半田付
は後、溶剤による洗浄がいちじるしく制約されるという
大きな問題があった。When polystyrene is used as a dielectric material, there is a further problem in chemical resistance, and washing with a solvent after soldering to a printed wiring board is severely restricted, which is a major problem.
本発明はこのような従来からの課題を解決し、音響機器
に用いて音質に優れ、なおかつ耐熱性と耐薬品性が良好
で、信頼性の高いコンデンサを提供しようとするもので
ある。The present invention aims to solve these conventional problems and provide a highly reliable capacitor that can be used in audio equipment and has excellent sound quality, has good heat resistance and chemical resistance, and has good heat resistance and chemical resistance.

が得られる。Polyphenylene sulfide as a working dielectric has superior heat resistance and chemical resistance compared to polypropylene, polystyrene, and polyethylene terephthalate. Furthermore, it is a dielectric material with low electrical loss and good frequency characteristics. Therefore, excellent characteristics as an acoustic capacitor can be obtained.

実 施 例
以下、本発明の音響用コンデンサの実施例について、第
１図を参照して説明する。Embodiments Hereinafter, embodiments of the acoustic capacitor of the present invention will be described with reference to FIG.
図は本実施例である０、１μＦの音響用コンデンサの断
面図であり、このコンデンサはポリフェニレンサルファ
イドフィルムと銅箔とを交互に重ね合わせて巻回してか
ら、リード線付けをし、外装を施したものである。The figure is a cross-sectional view of a 0.1 μF acoustic capacitor according to this embodiment. This capacitor is made by winding polyphenylene sulfide films and copper foils, then attaching lead wires and applying an exterior. This is what I did.
図において、１は厚さ６μｍのポリフェニレンサルファ
イドフィルム、２は厚さ７μｍの銅箔、３は外装樹脂、
４はリード線である。In the figure, 1 is a polyphenylene sulfide film with a thickness of 6 μm, 2 is a copper foil with a thickness of 7 μm, 3 is an exterior resin,
4 is a lead wire.
このコンデンサと、厚さ６μｍのポリプロピレンフィル

製造したコンデンサと、この銅に代えて厚さ７μｍの錫
箔を用いて製造した従来の音響用コンデンサ（いずれも
容量が０．１μＦ）を、直流（ＤＣ）印加電圧１５０Ｖ
、雰囲気温度１１０℃の条件下で寿命試験を実施した。This capacitor, a capacitor manufactured using a 6 μm thick polypropylene film and a 7 μm thick copper foil coated with a deterioration prevention film, and a conventional acoustic capacitor manufactured using a 7 μm thick tin foil instead of the copper. A capacitor (both have a capacity of 0.1 μF) is connected to a direct current (DC) applied voltage of 150 V.
A lifespan test was conducted under conditions of an ambient temperature of 110°C.
その結果を第２図に示す。The results are shown in FIG.
この結果から、本実施例のコンデンサが、従来の音響用
コンデンサに比べて、耐圧不良率、その他諸特性におい
て明らかに優れていることがわかる。From these results, it can be seen that the capacitor of this example is clearly superior to conventional acoustic capacitors in terms of breakdown voltage defect rate and other various characteristics.
これは、劣化防止膜を施した銅箔を用いたコンデンサに
おいては、その劣化防止膜の効果が特に高温度下では十
分ではなく、ポリプロピレンフィルム劣化が生じたこと
を示し、錫箔を用いたものにおいても、ポリプロピレン
フィルムそのものの耐熱性が十分でないため、同様の結
果となっている。This indicates that in capacitors using copper foil coated with a deterioration prevention film, the effect of the deterioration prevention film was not sufficient, especially at high temperatures, and deterioration of the polypropylene film occurred; Similar results were obtained because the polypropylene film itself did not have sufficient heat resistance.
しかし、それと比較して本発明のコンデンサにおいては
、耐圧不良やその他諸特性についても劣化が認められず
、耐熱性も十分で、銅によるポリフェニレンサルファイ
ドの劣化もないことがわかる。However, in comparison, in the capacitor of the present invention, no deterioration in breakdown voltage or other characteristics was observed, the heat resistance was sufficient, and it was found that the polyphenylene sulfide was not deteriorated by copper.
さらに、実際の音響機器にこれらのコンデンサを実装し
て、音質の評価を行った。その評価結果を第３図に示す
。Furthermore, we implemented these capacitors in actual audio equipment and evaluated the sound quality. The evaluation results are shown in Figure 3.
第３図の縦軸は一般的な音響機器業界での音質評価項目
を、横軸は音響用コンデンサではない一般のポリエチレ
ンテレフタレートフィルムを誘電体とし、アルミニウム
箔を電極としたコンデンサを基準に０とし、それよりよ
くなればプラス、悪くなればマイナスの評価をしたもの
である。The vertical axis in Figure 3 is the sound quality evaluation items in the general audio equipment industry, and the horizontal axis is 0 based on a capacitor whose dielectric is a general polyethylene terephthalate film, which is not an acoustic capacitor, and whose electrode is an aluminum foil. If the performance is better than that, it will be evaluated as positive, and if it is worse, it will be evaluated as negative.
試聴評価結果では、本発明のコンデンサは、すべての試
験項目において、従来の音響用コンデンサの音質と同等
かそれを上回る結果となっている。The listening evaluation results show that the capacitor of the present invention has sound quality equal to or better than that of conventional acoustic capacitors in all test items.
特に低音域においては非常に良好な結果となっている。The results are particularly good in the bass range.
これは、ポリフェニレンサルファイドの誘電率がポリプ
ロピレンやポリスチロールに比べて３．０と高い値を示
しているためである。そして、高音域において従来品と
同等の音質となっているのは、損失がポリプロピレンや
ポリスチロールと同程度の低い損失の誘電体であること
による。This is because the dielectric constant of polyphenylene sulfide is as high as 3.0 compared to polypropylene and polystyrene. The sound quality in the high frequency range is comparable to that of conventional products because it is a dielectric material with a loss as low as that of polypropylene or polystyrene.
さらに、本発明者等は、電極箔に錫箔を用いたコンデン
サにて試聴評価を実施したが、銅箔の場合と同様の良好
な結果を得た。Further, the present inventors performed listening evaluations on capacitors using tin foil as the electrode foil, and obtained good results similar to those obtained using copper foil.
