<P>PROBLEM TO BE SOLVED: To provide a high-quality sound loud speaker cable with less tone quality deterioration by reducing 'a magnetic induction action', 'a self induction action' and 'a skin effect' generated when a signal is applied to a loud speaker cable and improving a disturbance of transmitting frequency characteristics. <P>SOLUTION: Thin insulated wire cores having different colors to enable to discriminate a positive side and a negative side are twisted, of which a plurality of the twisted wires are integrated into a single wire, and is finished into a loud speaker cable by covering this single wire with a sheath. At both ends of the cable, the positive sides with the same color are mutually connected in a short-circuit state, and the negative sides with the same color are mutually connected in a short-circuit state. The both ends of the cable are connected according to the polarities of an amplifier and a loud speaker. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本発明は、オーディオ用アンプとスピーカーとを接続するスピーカーケーブルに関する。
【0002】
【従来の技術】
従来のスピーカーケーブルは、平行型、対撚り(ツイスト)型、4芯(スターカッド)型と構造は変っても、導線は細い単線を数多く束ねた太めの多芯撚り線構造のケーブルが主流である。また、高純度無酸素銅の様に直流抵抗を下げて伝送特性を良くしようとしている。しかし、直流抵抗を下げても、周波数の高い帯域では自己誘導(自己インダクタンス)が効いて来て、周波数の高いところで逆起電力が大きくなり、電流が流れにくくなり高域が出にくくなっている。
【0003】
また、周波数の高い電流は、銅線の表皮を流れ、周波数の低い電流は芯付近を流れる特性があり(表皮効果)、低音域と高音域で信号の通りやすさが変化してしまう。従来のスピーカーケーブルはいずれも、磁気誘導による振動、自己誘導や表皮効果の影響で伝送周波数特性の乱れが発生していた。
【0004】
【発明が解決しようとする課題】
本発明は、スピーカーケーブルに信号が流れた時発生する「磁気誘導作用」「自己誘導作用」「表皮効果」を軽減し、伝送周波数特性の乱れを改善し、音質劣化の少ない高音質スピーカーケーブルを提供することを目的としている。
【0005】
【課題を解決するための手段】
本発明は、プラス側とマイナス側が識別出来るよう色分けした、2本の細い絶縁線心を撚り合わせ、この撚り線を複数本束ねて一本にした構造を持つことを特徴とする。
【0006】
【発明の実施の形態】
ここに、本発明の実施の形態を示す。プラス側とマイナス側が識別出来るよう色分けした、細い絶縁線心を撚り合わせ、この撚り線を複数本束ねて一本にし、これにシースが被されてスピーカーケーブルに仕上げられている。
ケーブルの両端は、同色のプラス側は、プラス側同志を短絡接続し、同色のマイナス側は、マイナス側同志を短絡接続する。アンプ及びスピーカーの極性に合わせて接続する。
【0007】
【発明の効果】
2本の細い絶縁線心を撚り合わせることで、相寄る2本線に流れる電流が逆方向になり、磁束をキャンセルするため振動及び自己誘導が減小する。その結果高音域のリアリティーが向上する。
【0008】
導体周りの絶縁被覆が薄く互いにからみ合っているため振動を抑制する。
【0009】
複数本の線心がパラレルに接続されリッツ線状になっているので導体の表面積が大きくなり、表皮効果が軽減する。また、本数を増やすことで直流抵抗も低く抑えることができる。
【0010】
再生音は、全帯域にわたり信号の通過性がよいため過渡特性に優れ、音の立ち上がりが早く音像の輪郭がしっかり出るようになる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a speaker cable for connecting an audio amplifier and a speaker.
[0002]
[Prior art]
Conventional speaker cables have the same structure as the parallel type, twisted type (twisted) type, and 4-core (star quad) type. . Also, as with high-purity oxygen-free copper, the DC resistance is reduced to improve the transmission characteristics. However, even if the DC resistance is lowered, self-induction (self-inductance) is effective in a high frequency band, and the back electromotive force is increased at a high frequency band, so that it is difficult for a current to flow and a high band is hardly generated. .
[0003]
In addition, a high-frequency current flows through the skin of the copper wire, and a low-frequency current flows near the core (skin effect), and the ease with which a signal passes in low and high ranges changes. In all of the conventional speaker cables, transmission frequency characteristics have been disturbed due to the influence of vibration due to magnetic induction, self-induction, and skin effect.
[0004]
[Problems to be solved by the invention]
The present invention reduces the "magnetic induction effect", the "self-induction effect", and the "skin effect" that occur when a signal flows through a speaker cable, improves the disturbance of the transmission frequency characteristic, and reduces the sound quality deterioration. It is intended to provide.
[0005]
[Means for Solving the Problems]
The present invention is characterized in that it has a structure in which two thin insulated wires, which are color-coded so that the plus side and the minus side can be distinguished, are twisted, and a plurality of such twisted wires are bundled into one.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Here, an embodiment of the present invention will be described. A thin insulated wire core, which is color-coded so that the plus side and the minus side can be distinguished, is twisted, and a plurality of such twisted wires are bundled into one, which is covered with a sheath and finished into a speaker cable.
At both ends of the cable, the plus side of the same color short-circuits the plus sides, and the minus side of the same color short-circuits the minus sides. Connect according to the polarity of amplifier and speaker.
[0007]
【The invention's effect】
By twisting two thin insulated wires, the currents flowing in the two adjacent wires are in opposite directions, and the vibration and self-induction are reduced to cancel the magnetic flux. As a result, the reality of the high range is improved.
[0008]
Vibration is suppressed because the insulating coating around the conductor is thin and entangled with each other.
[0009]
Since a plurality of wire cores are connected in parallel to form a litz wire, the surface area of the conductor is increased, and the skin effect is reduced. In addition, the DC resistance can be suppressed low by increasing the number.
[0010]
The reproduced sound has excellent transient characteristics because the signal has good transmissivity over the entire band, and the sound rises quickly and the contour of the sound image comes out firmly.
