る。 According to recent research, in a stereo system, for example, the cartridge, amplifier, and speaker voice coil are connected in series with very long wires/cables, and the frequency range from low to high frequency (common sense is 20KHz). ) When music signals from up to known to cause deterioration.
音質の劣化は、このような自己発生振動だけで
なく、外部から電線・ケーブルに与えられる振動
によつても起こることが経験的に認められてい
る。 It has been empirically recognized that deterioration in sound quality occurs not only due to such self-generated vibrations, but also due to vibrations applied to electric wires and cables from the outside.

みについては有力な手段がなかつた。 The inventors have already proposed a method of reducing vibration transmission strain between insulated core wires (interphase) or outside by covering them with elastic memory material. There was no effective means for dealing with resonance distortion caused by vibration propagation.

る。[Problem to be solved by the invention] This is because the insulating materials and sheath materials of electric wires and cables are generally made of polyethylene, butyl rubber, vinyl chloride, etc., which have high elasticity, and their good vibration damping effect cannot be improved. This is because it doesn't last.

きるオーデイオ用電線・ケーブルの提供を目的と
するものである。 The present invention was developed based on the above, and aims to provide audio wires and cables that can reduce resonance distortion caused by the propagation of vibrations between insulated core wires or from external vibrations, and which can exhibit excellent acoustic effects. It is something.

とするものである。[Means for solving the problem] The audio wire/cable of the present invention has a plurality of insulated core wires arranged around the outer periphery of the center string, and the center string is
It is characterized in that it is made of Pb, Sn, or an alloy thereof, and that the insulated core wires are spaced apart from each other.
Pb，Snは多きなダンピング効果を有する金属

各絶縁心線相互を離隔して配置することにより外
部振動の伝播による共振歪みを除去できる。 Pb and Sn are metals that have a large damping effect, and they are placed at the center of the insulated core wire, and
By arranging the insulated core wires apart from each other, resonance distortion due to propagation of external vibrations can be eliminated.
［実施例］

おいて配置されている。 The insulated core wires 3 are arranged approximately symmetrically around the center string 4, and at slight intervals so that they do not touch each other.
オーデイオシステムに使用しときの音響効果は
数値計測の方法はなく、熟達した人間の聴感によ
つて評価するしかないが、聴感テストの結果は次
の通りである。 There is no way to numerically measure the acoustic effect when used in an audio system, and the only way to evaluate it is by the auditory senses of an experienced human, but the results of aural tests are as follows.
音域の広がりが大きく、ステレオ音の分散が
よい。 The sound range is wide and the dispersion of stereo sound is good.
微妙な余韻がきちんと聞きわけられる。 The subtle aftertaste can be clearly heard.
