【考案の詳細な説明】
本考案はオーデイオ機器、特にスピーカの配線
材として好適な電線の改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement in an electric wire suitable as a wiring material for audio equipment, particularly speakers.
オーデイオ機器で再生音を聞く場合、その音質
を支配するものには、回転形の精度、アンプの設
計、接続技術など、非常に多くの要素があるが、
最も大きな影響を及ぼすのはスピーカの特性であ
る。 When listening to playback sound from audio equipment, there are many factors that govern the sound quality, such as the accuracy of the rotation shape, amplifier design, and connection technology.
The biggest influence is on the characteristics of the speaker.
近時スピーカは、音質重視の設計思想から、周
波数最適化のため、二個以上のスピーカを組み合
せた、いわゆるマルチウエイスピーカシステムが
採用されている。 In recent years, speakers have been designed with a focus on sound quality, and a so-called multi-way speaker system, in which two or more speakers are combined, has been adopted for frequency optimization.
この場合、アンプ出力から音響情報は、ネツト
ワークを組んで各スピーカに分配されることにな
る。ところが狭いスピーカボツクス内で音響情報
を分配するため、配線材が相互に交又する個所が
必然的に生ずることになり、違う周波数によつて
振動している配線材の振動が、それと接している
他方の配線材に伝播し、一種のクロスオーバ現象
が生じ、フラツトな特性を得ることができない。 In this case, acoustic information from the amplifier output is distributed to each speaker by forming a network. However, in order to distribute acoustic information within a narrow speaker box, there will inevitably be places where the wiring materials intersect with each other, and the vibrations of the wiring materials vibrating at different frequencies will come into contact with each other. This propagates to the other wiring material, causing a kind of crossover phenomenon, making it impossible to obtain flat characteristics.
そしてひどい時にはビリビリと言ういわゆるビ
ビリ雑音が生ずる。 In severe cases, a so-called chattering noise occurs.
一方、これらの配線材は、撚線導体を締めつけ
る様な硬質絶縁体を用いた方が音質上好ましいこ
とが従来より明らかとなつているが、絶縁体が硬
質になればなるほど共振減衰係数が小さくなつ
て、上記した交叉する配線材の振動伝播が一層激
しく起るもので、相矛盾した特性を示しているの
が現情である。 On the other hand, it has long been clear that it is better for sound quality to use hard insulators that tighten the stranded wire conductors for these wiring materials, but the harder the insulators, the smaller the resonance damping coefficient. As a result, the vibration propagation of the above-mentioned intersecting wiring materials occurs even more intensely, and the current situation is that they exhibit contradictory characteristics.
本考案は、以上説明した従来技術の欠点を解決
し、スピーカの配線材として好適な改良された電
線の提供を目的として提案されたもので、その要
旨とするところは、複数本の素線を撚合せた撚線
導体の外周に、当該撚線導体を外部より定常的に
締め付ける硬質絶縁体を設け、該硬質絶縁体の外
周に共振防止層を設けて構成したことを特徴とす
るオーデイオ機器用電線にある。 The present invention was proposed for the purpose of solving the drawbacks of the prior art described above and providing an improved electric wire suitable as a wiring material for speakers. For audio equipment, characterized in that a hard insulator is provided on the outer periphery of the stranded conductor to tighten the stranded conductor regularly from the outside, and a resonance prevention layer is provided on the outer periphery of the hard insulator. It's on the wire.
上記において、撚線導体を定常的に締め付ける
硬質絶縁体としては、例えば、メルトインデツク
ス0.1、密度0.945の高密度ポリエチレンからなる
弾性記憶性テープ又はチユーブを撚線導体外周に
設け、それを熱収縮させたものがあげられる。 In the above, as a hard insulator that constantly tightens the stranded wire conductor, for example, an elastic memory tape or tube made of high-density polyethylene with a melt index of 0.1 and a density of 0.945 is provided around the outer periphery of the stranded wire conductor, and it is heat-shrinkable. I can give you what you gave me.
また共振防止層としては、多量の気泡を含有し
た発泡プラスチツク、ゴムの様に共振減衰係数の
大きい材料が好ましく、その他に中空チユーブを
所定間隔で絞り、絞り部で絶縁体を保持したいわ
ゆるバロン形チユーブ構造、あるいはエンボスフ
イルムを巻回した構造などであつても良い。 The anti-resonance layer is preferably made of a material with a large resonance damping coefficient, such as foamed plastic containing a large amount of air bubbles or rubber.In addition, a so-called ballon type material in which hollow tubes are squeezed at predetermined intervals and an insulator is held at the constricted portions is preferable. It may have a tube structure or a structure in which an embossed film is wound.
次に本考案の一実施例を添付図面を参照してさ
らに説明するに、１は導体であり、その外周には
延伸ポリエチレンテープ２が巻き回されており、
さらにその外周には、発泡ポリエチレン３が押出
被覆されている。 Next, an embodiment of the present invention will be further described with reference to the attached drawings. Reference numeral 1 is a conductor, and a stretched polyethylene tape 2 is wound around the outer circumference of the conductor.
Furthermore, the outer periphery is extruded and coated with foamed polyethylene 3.
導体１としては、無酸素銅の極細素線をエナメ
ルメツキし、これを大量に集合撚線したものが使
用される。 As the conductor 1, a large number of enamel-plated ultrafine strands of oxygen-free copper strands are used.
素線として、純度の高い無酸素銅を使用し、電
流の表皮効果を防止するためリツツ線構造として
いるため、ナチユラルで広帯域をカバーする再生
音が得られる。 Highly pure oxygen-free copper is used as the wire, and a wire structure is used to prevent the skin effect of current, resulting in natural reproduction sound that covers a wide range.
延伸ポリエチレンテープ２は巻回された後、結
晶転移点付近まで加熱されるもので、そのため収
縮を起し、この収縮力は導体１を常に中心方向に
締付力として作用するもので、鋭いとおりの良い
再生音が得られる。 After the stretched polyethylene tape 2 is wound, it is heated to near the crystal transition point, which causes it to contract. You can get good playback sound.
発泡ポリエチレン押出層３は、多量の気泡の在
存により、スピーカ出力端から反射された機械的
振動を吸収減衰させる共振防止層として作用する
もので、スピーカボツクス内に交叉して配線され
た他方の電線に共振を起させることがない。 Due to the presence of a large amount of air bubbles, the extruded foamed polyethylene layer 3 acts as a resonance prevention layer that absorbs and attenuates mechanical vibrations reflected from the speaker output end. Does not cause resonance in the wire.
その結果クロスオーバ現象がなくフラツトな特
性が得られ、又オーデイオ機器の致命的なビビリ
雑音となつてスピーカに導入されることはなくな
る。 As a result, a flat characteristic without a crossover phenomenon is obtained, and chatter noise, which is fatal to audio equipment, is not introduced into the speaker.
尚、従来電線同志の交叉がない場合であつて
も、スピーカを構成するキヤビネツトあるいはバ
ツフル板などの振動に共鳴して共振を起す現象が
あつたが、本実施例電線の場合は、空気振動を吸
収減衰せしめ、ビビリ雑音を発生することが全く
ない。 In the past, even when wires did not cross each other, there was a phenomenon in which they resonated with the vibrations of the cabinet or bumper plate that constituted the speaker, but in the case of the wire of this example, air vibrations could be caused. It absorbs and attenuates, and does not generate any chatter noise.
本考案は以上説明した本実施例にのみ限定解釈
されるものではなく、いくつかの変形も考え得る
が、それらも本考案に含まれる。 The present invention is not limited to the embodiments described above, and some modifications may be considered, but these are also included in the present invention.
以上説明した通り、本考案電線は、硬質絶縁体
層の存在により、優れた再生音をオーデイオ機器
から引き出すことができ、又、共振防止層の存在
により、ビビリ雑音のないフラツトな特性の再生
音が得られるものであり、その価値は非常に大な
るものがある。 As explained above, the present electric wire is able to extract excellent sound reproduction from audio equipment due to the presence of the hard insulating layer, and also allows reproduction sound with flat characteristics without chatter noise due to the presence of the anti-resonance layer. can be obtained, and its value is extremely great.
