Description
本発明は、オーディオ機器用のアクセサリに関し、より詳細には、インシュレーターの機能を有するアクセサリに関する。 The present invention relates to an accessory for audio equipment, and more particularly to an accessory having an insulator function.
一般に、アンプ、スピーカー、ＣＤプレイヤー、レコードプレイヤーといったオーディオ機器は、振動に弱く、振動を多く受けると、音質が劣化することが知られている。オーディオ機器は、いずれもそれ自体が内部に振動源を有していることに加え、その設置面を介して外部からの振動の影響を受け易いことから、原音の再現を追及するオーディオマニアの間では、機器の内部振動を吸収するとともに、外部からの振動を遮断する目的で、オーディオ機器と設置面の間にインシュレーターを配置することが常識となっている（例えば、特許文献１）。 In general, it is known that audio equipment such as an amplifier, a speaker, a CD player, and a record player is vulnerable to vibration, and that the sound quality deteriorates when receiving a lot of vibration. Since all audio devices have their own vibration sources, they are easily affected by external vibrations through the installation surface, so there is no difference between audio enthusiasts seeking to reproduce the original sound. Then, it is common sense to arrange an insulator between an audio device and an installation surface for the purpose of absorbing internal vibration of the device and blocking external vibration (for example, Patent Document 1).
現在、オーディオ機器用のインシュレーターとして、金属、木材、ゴム、樹脂、セラミックといった様々な材料を用いた商品が流通しており、その形状にも、円板型、キューブ型、円錐形のスパイクを用いて一点で支持するタイプなど、多くのバリエーションがある。 Currently, products using various materials such as metal, wood, rubber, resin, and ceramics are distributed as insulators for audio equipment, and the shape is also disc-shaped, cube-shaped, or conical spikes. There are many variations, such as a type that supports at a single point.
本発明は、新規なオーディオ機器用アクセサリを提供することを目的とする。 An object of the present invention is to provide a novel accessory for audio equipment.
本発明者は、オーディオ機器用のインシュレーターとして有望な新規の素材を見出すべく、様々な素材について数多くの聴感試験を行った結果、フッ素ゴム製のＯリングをインシュレーターとして使用した場合に癖の無い自然なサウンドが得られることを発見した。その後、本発明者は、さらに、検討を進める過程で、フッ素ゴム製のＯリングが持つ聴感上の問題を克服する方法を発見し、本発明に至ったのである。 The present inventor conducted numerous hearing tests on various materials in order to find a promising new material as an insulator for audio equipment. I found that it was possible to get a good sound. Thereafter, the inventor further discovered a method for overcoming the audibility problem of the fluororubber O-ring in the course of further study, and reached the present invention.
すなわち、本発明によれば、オーディオ機器用のアクセサリである、帯電防止被膜が形成されたフッ素ゴム製のＯリングが提供される。 That is, according to the present invention, there is provided an O-ring made of fluororubber having an antistatic coating film, which is an accessory for audio equipment.
上述したように、本発明によれば、インシュレーターの機能を有する新規なオーディオ機器用アクセサリが提供される。 As described above, according to the present invention, a novel accessory for audio equipment having the function of an insulator is provided.
以下、本発明を図面に示した実施の形態をもって説明するが、本発明は、図面に示した実施の形態に限定されるものではない。 Hereinafter, the present invention will be described with reference to embodiments shown in the drawings, but the present invention is not limited to the embodiments shown in the drawings.
図１に示すフローチャートに基づいて、本発明の実施形態であるオーディオ機器用アクセサリの製造方法を説明する。 Based on the flowchart shown in FIG. 1, the manufacturing method of the accessory for audio equipment which is embodiment of this invention is demonstrated.
（工程１）
フッ素ゴム製のＯリングを用意する。フッ素ゴムは、優れた耐熱性、耐油性、耐圧性、耐薬品性を有するゴムであり、通常、フッ化ビニリデン系のフッ素ゴムがＯリングに用いられる。
(Process 1)
Prepare an O-ring made of fluoro rubber. Fluoro rubber is a rubber having excellent heat resistance, oil resistance, pressure resistance, and chemical resistance, and usually vinylidene fluoride type fluoro rubber is used for the O-ring.
（工程２）
帯電防止剤の溶液（以下、帯電防止液という）を用意する。帯電防止剤とは、絶縁体の表面に対してわずかな導電性を付与することにより静電気の蓄積を防止する薬剤である。帯電防止剤の多くは界面活性剤を含有しており、物体表面に形成された界面活性剤の膜は、空気中の水分を吸着することで物体表面の電気抵抗を下げ、表面の帯電を防止する。
(Process 2)
An antistatic agent solution (hereinafter referred to as an antistatic solution) is prepared. An antistatic agent is an agent that prevents accumulation of static electricity by imparting a slight electrical conductivity to the surface of an insulator. Many antistatic agents contain a surfactant, and the surfactant film formed on the surface of the object reduces the electrical resistance of the object surface by adsorbing moisture in the air, preventing the surface from being charged. To do.
（工程３）
帯電防止液にフッ素ゴム製Ｏリングを浸漬する。なお、別の実施形態では、帯電防止液をスプレーや刷毛を使用してＯリングに直接塗布してもよい。
(Process 3)
Immerse the fluororubber O-ring in the antistatic solution. In another embodiment, the antistatic liquid may be applied directly to the O-ring using a spray or a brush.
（工程４）
帯電防止液の中からフッ素ゴム製Ｏリングを取り出して自然乾燥し、帯電防止液の溶媒を揮発させる。その結果、本実施形態のオーディオ機器用アクセサリとして、表面に帯電防止剤の被膜（以下、帯電防止被膜という）が形成されたフッ素ゴム製Ｏリングが得られる。
(Process 4)
The fluororubber O-ring is taken out of the antistatic liquid and dried naturally, and the solvent of the antistatic liquid is volatilized. As a result, a fluororubber O-ring having an antistatic agent film (hereinafter referred to as an antistatic film) formed on the surface is obtained as an accessory for audio equipment of the present embodiment.
続いて、本実施形態のオーディオ機器用アクセサリ（すなわち、帯電防止被膜付きフッ素ゴム製Ｏリング）の使用方法を説明する。 Next, a method of using the audio device accessory of this embodiment (that is, a fluororubber O-ring with an antistatic coating) will be described.
第１に、本実施形態の帯電防止被膜付きフッ素ゴム製Ｏリングは、オーディオ機器用のインシュレーターとして使用することができる。使用方法は、従来のインシュレーターと同じであり、オーディオ機器と設置面の間にＯリングを配置する。図２（ａ）は、本実施形態のＯリング１０をアンプのインシュレーターとして使用した状態を例示的に示し、図２（ｂ）は、本実施形態のＯリング１０をスピーカーのインシュレーターとして使用した状態を例示的に示す。 First, the fluororubber O-ring with antistatic coating of this embodiment can be used as an insulator for audio equipment. The usage method is the same as that of a conventional insulator, and an O-ring is arranged between the audio device and the installation surface. FIG. 2A exemplarily shows a state in which the O-ring 10 of the present embodiment is used as an amplifier insulator, and FIG. 2B shows a state in which the O-ring 10 of the present embodiment is used as an insulator of a speaker. Is exemplarily shown.
第２に、本実施形態の帯電防止被膜付きフッ素ゴム製Ｏリングは、いわゆる「鳴き止め」に利用することができる。具体的には、鳴きを止めたい部分に適切な内径の本実施形態のＯリング１０を嵌めてきつく締め付けることで、その部分の共鳴を防ぐという方法である。図３（ａ）は、ＲＣＡケーブルのコネクターに本実施形態のＯリング１０を嵌めた状態を例示的に示し、図３（ｂ）は、ワイアレスイヤフォンの筐体に本実施形態のＯリング１０を嵌めた状態を例示的に示す。この他にも、各種オーディオ機器のノブ、オーディオラックの支柱、スピーカースタンドの支柱、といった円柱状の部品に本実施形態のＯリング１０を嵌めることで、鳴きを止めて音質を向上させることができる。 Second, the fluororubber O-ring with antistatic coating of the present embodiment can be used for so-called “squeaking”. Specifically, the O-ring 10 of the present embodiment having an appropriate inner diameter is fitted into a portion where it is desired to stop squeaking and tightened, thereby preventing resonance at that portion. FIG. 3A exemplarily shows a state in which the O-ring 10 of the present embodiment is fitted to the connector of the RCA cable, and FIG. 3B shows the O-ring 10 of the present embodiment in the case of the wireless iphone. The fitted state is exemplarily shown. In addition, by fitting the O-ring 10 of this embodiment to cylindrical parts such as knobs of various audio devices, audio rack columns, speaker stand columns, etc., it is possible to stop noise and improve sound quality. .
最後に、本実施形態の帯電防止被膜付きフッ素ゴム製Ｏリングが聴感にもたらす効果について説明する。 Finally, the effect of the fluororubber O-ring with the antistatic coating of this embodiment on hearing is explained.
インシュレーターとしてのＯリングは、既存のインシュレーターと比較して体積が格段に小さいため、その分、材料（ゴム）に由来する共振成分が音信号に与える影響が小さくなるという利点を持つ。また、インシュレーターとしてのＯリングは、その接地面積が非常に小さいため、振動の遮断性に優れているという利点を持つ。 The O-ring as an insulator has an advantage that the influence of the resonance component derived from the material (rubber) on the sound signal is reduced correspondingly because the volume is much smaller than that of the existing insulator. In addition, an O-ring as an insulator has an advantage that it has excellent vibration blocking properties because its ground contact area is very small.
その中でも、フッ素ゴム製のＯリングは、他のゴム製のＯリングに比べて、ゴムに由来する共振成分（付帯音）が非常に少ないという特徴を有し、癖の無い自然な聴感が得られるという利点がある。 Among them, the O-ring made of fluoro rubber has a feature that there are very few resonance components (accompanying sound) derived from rubber compared with other O-rings made of rubber, and a natural hearing feeling without wrinkles is obtained. There is an advantage that
そのようなフッ素ゴム製Ｏリングに対して、さらに、帯電防止処理を施すことによって、その理由は不明であるが、帯電防止処理を施さない場合と比較して、倍音成分が減少し、音の歪みが低減されるという効果を奏する。 The reason for this is further unknown by applying antistatic treatment to such a fluororubber O-ring, but the overtone component is reduced compared to the case where antistatic treatment is not applied, and There is an effect that distortion is reduced.
以上、本発明について実施形態をもって説明してきたが、本発明は上述した実施形態に限定されるものではなく、本発明の趣旨を逸脱しない限りにおいて、様々な変更、修正、改良等が可能である。 Although the present invention has been described with the embodiment, the present invention is not limited to the above-described embodiment, and various changes, modifications, improvements, and the like can be made without departing from the spirit of the present invention. .
以下、本発明のオーディオ機器用アクセサリ（すなわち、帯電防止被膜付きフッ素ゴム製Ｏリング）について、実施例を用いてより具体的に説明を行なうが、本発明は、後述する実施例に限定されるものではない。 Hereinafter, the audio device accessory of the present invention (that is, a fluororubber O-ring with an antistatic coating) will be described more specifically with reference to examples. However, the present invention is limited to the examples described later. It is not a thing.
＜帯電防止被膜付きフッ素ゴム製Ｏリングの作製＞
帯電防止液（帯電防止剤をイソプロプルアルコールに溶解してなる液）と、フッ素ゴム製のＯリングを用意し、Ｏリングを帯電防止液に軽く浸した後、アルコールが揮発するまで自然乾燥することによって、帯電防止被膜付きフッ素ゴム製Ｏリング（以下、実施例という）を得た。
<Production of fluororubber O-ring with antistatic coating>
Prepare an antistatic solution (a solution obtained by dissolving an antistatic agent in isopropyl alcohol) and a fluororubber O-ring. Lightly immerse the O-ring in the antistatic solution and let it dry naturally until the alcohol volatilizes. As a result, an O-ring made of fluororubber with an antistatic coating (hereinafter referred to as Example) was obtained.
＜聴感試験１＞
オーディオ機器（ネットワークプレーヤー N-50、パイオニア株式会社製）の本体を支持する４個の脚部と設置面の間に実施例のＯリングを一つずつ配置した状態で、ハイレゾ音源を再生し、その音色を、音響機器開発のエンジニアに試聴してもらった。
<Hearing test 1>
With the four O-rings that support the main body of the audio device (Network Player N-50, manufactured by Pioneer Corporation) and the O-ring of the example placed one by one, the high-resolution sound source is played. The sound was auditioned by an audio equipment development engineer.
比較例として、帯電防止被膜が形成されていない４種類のＯリング（比較例１〜４）とマグネシウム製の円板型インシュレーター（比較例５）を使用して、上述したのと同様の条件で聴感試験を行った。なお、本実験に使用したＯリングとインシュレーターの詳細を下記表１にまとめて示す。 As a comparative example, four kinds of O-rings (Comparative Examples 1 to 4) in which an antistatic coating is not formed and a disk type insulator made of magnesium (Comparative Example 5) are used under the same conditions as described above. A hearing test was conducted. The details of the O-ring and insulator used in this experiment are summarized in Table 1 below.
＜評価結果＞

<Evaluation results>
The engineer in charge of the trial listening evaluated the audibility when the examples and comparative examples 1 to 5 were arranged as insulators based on the reproduced sound in a state where no insulator was arranged as follows.
（比較例１：ニトリルゴム製Ｏリング）
音抜けが悪く、ダイナミックレンジ（帯域）が狭く、解像度が甘く、音がダブついており、高域部に違和感のある付帯音を感じる。
(Comparative Example 1: Nitrile rubber O-ring)
Sound loss is bad, dynamic range (band) is narrow, resolution is sweet, sound is dubbed, and there is an incidental sound with a sense of incongruity in the high frequency range.
（比較例２：エチレンプロピレン製Ｏリング）
解像度とレスポンスは良いが、音が高域に寄ってしまってバランスが崩れており、余韻感もかなり薄い。
(Comparative Example 2: O-ring made of ethylene propylene)
The resolution and response are good, but the sound has shifted to the high frequencies and the balance is lost, and the reverberation is quite thin.
（比較例３：シリコンゴム製Ｏリング）
音のバランスが高域寄りで低域が乏しく、ダイナミックレンジ（帯域）が狭い。
(Comparative Example 3: Silicon rubber O-ring)
The sound balance is close to the high range, the low range is poor, and the dynamic range (band) is narrow.
（比較例４：フッ素ゴム製Ｏリング）
音の解像度や上下左右の広がり感が良く、情報量や前後の厚みが増し、全帯域のバランスが良く、癖の無い自然な音質。ただし、解像度が増した分、余韻感がやや少なく淡泊なサウンド。また、音に若干の歪みがある。
(Comparative Example 4: O-ring made of fluoro rubber)
Sound resolution and a sense of spaciousness in the upper, lower, left, and right directions, an increased amount of information and thickness in the front and rear, a good balance of all bands, and a natural sound quality with no wrinkles. However, the amount of reverberation is slightly less because of the increased resolution. There is also some distortion in the sound.
（実施例：帯電防止被膜付きフッ素ゴム製Ｏリング）
音の密度が濃く、音が滑らかで、音の輪郭がハッキリしており、余韻感も十分で、ハイファイなサウンド感。また、比較例４で感じた音の歪みが消えている。
(Example: O-ring made of fluororubber with antistatic coating)
The sound density is high, the sound is smooth, the outline of the sound is clear, the reverberation is enough, and the sound is high fidelity. Moreover, the distortion of the sound felt in Comparative Example 4 disappears.
（比較例５：マグネシウム製円板型インシュレーター）
音の解像度や広がり感は増すが、実施例と比べると、若干マグネシウム固有の音がのっている感じがする。
(Comparative Example 5: Magnesium disk insulator)
Although the resolution and spread of the sound increase, compared to the embodiment, there is a feeling that the sound peculiar to magnesium is slightly applied.
＜聴感試験２＞
帯電防止被膜付きフッ素ゴム製のＯリングをワイアレスイヤフォン（AirPods、アップル社製）の筐体の棒状部分に嵌めた状態で、ハイレゾ音源を再生し、その音色を、音響機器開発のエンジニアに試聴してもらったところ、音の解像度や低域の量感が良くなり、イヤフォン特有の薄い音が軽減され、生々しいサウンドになった、という評価を得た。
<Hearing test 2>
Playing a high-resolution sound source with an O-ring made of fluororubber with antistatic coating fitted to the rod-shaped part of the case of a wireless iphone (AirPods, Apple), and listening to the sound engineer engineer As a result, the sound resolution and low-frequency volume were improved, and the thin sound peculiar to earphones was reduced, resulting in a vivid sound.
