Description

【0001】
【発明の属する技術分野】
この発明は、各種音響機器として使用されるスピーカの構成部材であるダンパ、さらに詳しくはその面上に錦糸線を装着一体化したスピーカ用ダンパおよびその製造方法に関する。
【0002】
【従来の技術】
一般にスピーカのボイスコイルはダンパを介し振動可能に支持されている。
【0003】
また、ボイスコイルのリード線とスピーカの入力端子とは錦糸線によって接続されており、この錦糸線は、通常、振動板とダンパの間の空間に配されるので、動作時に揺動して振動板やダンパに当たって異常音を発生する等の問題があり、スピーカの小型化、薄型化が進むとこの傾向はより顕著となってくる。
【0004】
この問題を解決するために、最近では接着や縫着等の手段により、ダンパに錦糸線を装着し一体化したものが提供されている。
【0005】
この先行例としては、例えば特開平2−134100号が存在する。このスピーカ用ダンパは、錦糸線に相当する導電部材をダンパ素材に縫着した構成となっている。
【0006】
また、他の先行例としては、実開平4−71099号が存在する。この先行例では、ダンパにウレタン系発泡樹脂からなる軽量発泡体を接着固定し、この軽量発泡体に錦糸線を装着する構成としている。
【0007】
【発明が解決しようとする課題】
しかしながら、前者の特開平2−134100号においては、コルゲーションの形状に沿わせて内周部から外周部に導電部材をミシンと糸とを用いて縫い付けるため、作業が煩雑であり、生産性が悪く、動作時の追従性も悪いという課題があった。
【0008】
また、後者の実開平4−71099号では、軽量発泡体をダンパに接着する工程と軽量発泡体上に錦糸線を装着する工程とが必要であるため、作業が煩雑であるうえに、ダンパのコルゲーションの山の上に軽量発泡体が重ねて装着されるため、この部分の厚みが大幅に増加してしまい、スピーカの薄型化のニーズには応えられないという課題があった。
【0009】
この発明は上記のことに鑑み提案されたもので、その目的とするところは、製造を容易とし、追従性にも優れ、スピーカの薄型化にも適した、錦糸線装着スピーカ用ダンパおよびその製造方法を提供することにある。
【0010】
【課題を解決するための手段】
この発明は、布基材を熱成形して、同心円状の複数のコルゲーション2を設けたダンパ本体1Aの一方の面aに、前記コルゲーション2の形状に沿わせて、ダンパ本体1Aの外周端3と内周端4とを結ぶ方向に錦糸線を装着したスピーカ用ダンパにおいて、前記錦糸線は平編の薄い錦糸線5からなり、かつダンパ本体1Aと平編錦糸線5との間に設けた帯状のポリウレタン6の熱融着により一体化する構成とし、上記目的を達成している。
【0011】
すなわち、上記錦糸線は、中心糸30番手単糸以下のメタ系アラミッド繊維に母線径0.08mm以下の銅線を線径の1/4以下に圧延した銅箔を巻き付けた単位錦糸線を13本集合して厚さ0.58mm以下の平編とした平編錦糸線5を用いることにより、上記目的を達成している。
【0012】
さらに、上記スピーカ用ダンパは、布基材にフェノール樹脂の如き熱硬化性樹脂を含浸した後、一方の金型上に載置し、この布基材の上に帯状のポリウレタン6を載置し、さらにこの帯状のポリウレタン6の上に長手方向に沿って中心糸30番手単糸以下のメタ系アラミッド繊維に母線径0.08mm以下の銅線を線径の1/4以下に圧延した銅箔を巻き付けた単位錦糸線を13本集合して厚さ0.58mm以下の平編とした平編錦糸線5を載置し、もう一方の金型を押下し加熱加圧成形することにより、同心円状のコルゲーション2を有するダンパ本体1Aを形成すると同時に、ポリウレタン6の融着により平編錦糸線5をダンパ本体1Aに一体化して製造するようにし、かつこの場合に用いるポリウレタン6としては、軟質ポリウレタンフォームとしたことに特徴を有している。
【0013】
【発明の実施の形態】
図1は本発明にかかるスピーカ用ダンパの第1実施例の斜視図である。このダンパ1は、リング状をなし、同心円状の複数のコルゲーション2が形成されたダンパ本体1Aの一方の面a上に、波状をなすコルゲーション2の形状に沿わせてダンパ本体1Aの外周端3から内周端4にかけて一対の平編錦糸線5が帯状のポリウレタン6を介し配置され、このポリウレタン6は軟質ポリウレタンフォームからなり、その融着によって平編錦糸線5とダンパ本体1Aとは一体化されている。すなわち、これらはダンパ成形時に一体化され、ポリウレタン6も平編錦糸線5もコルゲーションの凹凸に沿った形でダンパ本体1Aに密着され、全体として薄形構造となっている。
【0014】
このダンパ基材としては、木綿繊維、アクリル繊維、ポリエステル繊維、アラミッド繊維等の単独または混紡からなる織布が用いられる。
【0015】
また、ポリウレタン6として軟質ポリウレタンフォームを用いているのは、この軟質ポリウレタンフォームは材質が柔らかく、布素材とのマッチングもよく、追従性を損なうことがなく、熱成形時の融着により平編錦糸線5をダンパ本体1Aに強固に一体化することができ、成形が容易であるからである。
【0016】
また、平編錦糸線5としては、中心糸30番手単糸以下のメタ系アラミッド繊維に母線径0.08mm以下の銅線を線径の1/4以下に圧延した銅箔を巻き付けた単位錦糸線を13本集合して厚さ0.58mm以下の平編としたものを用いている。
【0017】
すなわち、従来の錦糸線は、例えば中心糸40番手2本撚りのメタ系アラミッド繊維に母線径0.1mm程度の銅線を圧延してなる銅箔を巻き付けるなどしたものを用いるなどし、このものは厚さ0.72mm程度のため、所望のダンパ性能も得難い欠点があった。
【0018】
本発明では平編錦糸線5を極細の単線を平編に集合させた薄い帯状としている。
【0019】
このように錦糸線を薄くすると、ダンパ成形時の金型ギャップとダンパ布材との密着性が向上するため、コルゲーション2の形状が安定してダンパ1としての性能を損なうことがない。さらに平編錦糸線5の厚さが薄いと振動による屈曲性能が向上するため、耐久性も改善される。
【0020】
この平編錦糸線5は上述のように、従来使用されているものより薄い平編構造のものを採用しているので、屈曲性に富み、ダンパ性能を損なうことがなく、良好な性能を得ることができる。
【0021】
しかして、一対の平編錦糸線5は、第1実施例では、図示のように、リング状のダンパ本体1Aの外周の一端から他端にかけて直径方向に一連に設けられ、これに伴って一対の帯状のポリウレタン6も同様にして直径方向にそれぞれ設けられている。
【0022】
このように直径方向に一連に設けたのは、生産性が良く、かつ振動バランスも良いためである。
【0023】
しかしながら、実際の使用に際しては、ダンパ本体1Aの開口部7の内周端4からダンパ本体1Aの外周端3に向かって延びる何れか一方の半径部分側のものが用いられる。
【0024】
すなわち、図2は各平編錦糸線5を端子板12の各端子接続部13に接続した一使用例の斜視図を示し、左側の半径部分側を用いた例を示す。
【0025】
図2において、ダンパ本体1Aの内側の開口部7の周縁部、つまりダンパ本体1Aの内周端4は円筒状のボビン10の外周部に接着剤を介し結合される。また、何れか一方の半径部分側に設けられた各平編錦糸線5の内端部はボイスコイル11の巻始め、巻終わりの引出線(図示せず)にそれぞれ電気的に接続される。
【0026】
平編錦糸線5の外端部は端子板12の端子接続部13に接続される。
【0027】
なお、端子板12は、周知のように、ほぼ矩形をなす絶縁性のラグ板14と、このラグ板14に設けられた一対の端子13aとを備え、端子板12はスピーカを構成するフレーム(図示せず)に固着される。
【0028】
また、ボビン10には振動板(図示せず)が結合され、かつダンパ本体1Aの外周部はフレームに結合されるものである。
【0029】
次に上記構成のダンパ本体1Aの製造方法について説明する。
【0030】
まず、木綿繊維等の如き布からなる所定形状の布基材にフェノール樹脂の如き熱硬化性樹脂を含浸する。その後、一方の金型(図示せず)上にそれぞれ載置し、この布基材の上に帯状のポリウレタン6を載置し、さらにこの帯状のポリウレタン6の上に長手方向に沿って一対の平編錦糸線5を載置し、もう一方の金型(図示せず)を押下し加熱加圧成形することにより、同心円状のコルゲーション2を有するダンパ本体1Aを形成すると同時に、ポリウレタン6の融着により平編錦糸線5をダンパ本体1Aに容易に一体化し得、上記した本発明にかかるダンパ1を製造することができる。
【0031】
図3は本発明の第2実施例の斜視図を示す。
【0032】
この実施例では、帯状のポリウレタン6および一対の平編錦糸線5を、リング状のダンパ本体1Aの一方の面aの一方の半径部分側にのみ設けた点に特徴を有している。
【0033】
この場合、第1実施例に比べ、ポリウレタン6と平編錦糸線5との材料が半分ですむため、その分、材料費を節約し得る。
【0034】
なお、その他の構成および製造方法は基本的に第1実施例と同様である。
【0035】
図4は本発明の第3実施例を斜視図を示す。
【0036】
この実施例では、端子板の形状などに対応すべく、帯状のポリウレタン6および一対の平編錦糸線5を、ダンパ本体1Aの一方の面aの半径部分において、内周端4から外周端3に向かって、ほぼハの字状に広がるように設けた点に特徴を有している。
【0037】
他の構成などは第1実施例と同様である。
【0038】
【発明の効果】
以上のように本発明によれば、薄型であり、かつ平編錦糸線5はいちいちダンパ本体1Aに縫いつける必要がなく、ポリウレタン6を介しダンパ本体1Aに一体化できるため、製造が容易である。
【0039】
また、平編錦糸線5は極薄で折曲性が良いため、コルゲーション2の形状に沿ってダンパ本体1A上に設けることができ、追従性に優れ、スピーカの薄型化に適したダンパ1を得ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a damper that is a constituent member of a speaker used as various acoustic devices, and more particularly to a speaker damper in which a tinsel wire is mounted and integrated on the surface thereof and a method for manufacturing the same.
[0002]
[Prior art]
Generally, a voice coil of a speaker is supported through a damper so as to vibrate.
[0003]
Also, the lead wire of the voice coil and the input terminal of the speaker are connected by a tinsel wire, and this tinsel wire is usually arranged in the space between the diaphragm and the damper, so that it swings and vibrates during operation. There is a problem that an abnormal sound is generated by hitting a plate or a damper, and this tendency becomes more remarkable as the speaker becomes smaller and thinner.
[0004]
In order to solve this problem, recently, a unit in which a tinsel wire is attached to and integrated with a damper by means such as adhesion or sewing has been provided.
[0005]
As this prior example, for example, Japanese Patent Laid-Open No. 2-134100 exists. This damper for a speaker has a configuration in which a conductive member corresponding to a tinsel wire is sewn to a damper material.
[0006]
As another prior example, Japanese Utility Model Laid-Open No. 4-71099 exists. In this prior example, a lightweight foam made of urethane-based foamed resin is bonded and fixed to a damper, and a tinsel wire is attached to the lightweight foam.
[0007]
[Problems to be solved by the invention]
However, in the former JP-A-2-134100, the conductive member is sewn from the inner peripheral portion to the outer peripheral portion using a sewing machine and a thread along the shape of the corrugation, so that the work is complicated and the productivity is low. There was a problem that the followability during operation was bad.
[0008]
In the latter actual Japanese Utility Model Laid-Open No. 4-71099, a process of adhering the lightweight foam to the damper and a process of attaching the tinsel wire on the lightweight foam are necessary, and the work is complicated. Since the lightweight foam is mounted on top of the corrugation pile, the thickness of this portion is greatly increased, and there is a problem that the need for reducing the thickness of the speaker cannot be met.
[0009]
The present invention has been proposed in view of the above, and the object of the present invention is to provide a damper for a tinsel wire-mounted speaker that is easy to manufacture, has excellent followability, and is suitable for thinning the speaker, and its manufacture It is to provide a method.
[0010]
[Means for Solving the Problems]
In the present invention, the outer peripheral end 3 of the damper main body 1A is formed along the shape of the corrugation 2 on one surface a of the damper main body 1A provided with a plurality of concentric corrugations 2 by thermoforming a cloth base material. In the speaker damper in which the tinsel wire is mounted in the direction connecting the inner peripheral end 4 to the inner circumferential end 4, the tinker wire is composed of a flat knitted thin tinsel wire 5 and provided between the damper main body 1A and the flat knitted tinsel wire 5. The structure is integrated by heat-sealing the belt-like polyurethane 6 to achieve the above object.
[0011]
That is, the above-mentioned tinsel wire is a unit bronze wire obtained by winding a copper foil obtained by rolling a copper wire having a bus bar diameter of 0.08 mm or less to ¼ or less of the wire diameter around a meta aramid fiber having a center yarn of 30 count or less. By using the flat knitted bronze wire 5 which is a flat knitting having a thickness of 0.58 mm or less by gathering the main assembly, the above object is achieved.
[0012]
Further, the speaker damper has a cloth base material impregnated with a thermosetting resin such as phenol resin, and is then placed on one mold, and a belt-like polyurethane 6 is placed on the cloth base material. Further, a copper foil obtained by rolling a copper wire having a bus wire diameter of 0.08 mm or less onto the strip-like polyurethane 6 along the longitudinal direction to a meta aramid fiber having a center yarn of 30 count or less along the longitudinal direction to 1/4 or less of the wire diameter. A flat knitted silk wire 5 having a flat knitting thickness of 0.58 mm or less is put on a set of 13 unit kinshi wires wound with wire, and the other mold is pressed and heated and pressed to form a concentric circle. The damper main body 1A having the corrugated corrugation 2 is formed, and at the same time, the flat knitted tinsel wire 5 is integrated with the damper main body 1A by fusing the polyurethane 6, and the polyurethane 6 used in this case is a soft polyurethane. It is characterized in that the Omu.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of a first embodiment of a speaker damper according to the present invention. The damper 1 has a ring shape, and the outer peripheral end 3 of the damper main body 1A is formed on one surface a of the damper main body 1A on which a plurality of concentric corrugations 2 are formed along the corrugated corrugation 2. A pair of flat knitted tinsel wires 5 are arranged from the outer peripheral edge 4 to the inner peripheral edge 4 via a strip-like polyurethane 6, which is made of a soft polyurethane foam, and the flat knitted tinsel wire 5 and the damper main body 1A are integrated by fusion. Has been. That is, they are integrated at the time of damper molding, and both the polyurethane 6 and the flat knitted bronze wire 5 are in close contact with the damper main body 1A along the corrugation irregularities to form a thin structure as a whole.
[0014]
As the damper base material, a woven fabric made of single or mixed spinning of cotton fiber, acrylic fiber, polyester fiber, aramid fiber or the like is used.
[0015]
In addition, the flexible polyurethane foam is used as the polyurethane 6 because the soft polyurethane foam is soft in material, matches well with the cloth material, does not impair the follow-up property, and does not impair the followability. This is because the wire 5 can be firmly integrated with the damper main body 1A and can be easily molded.
[0016]
Further, as the flat knitted bronze wire 5, a unit bronze yarn obtained by winding a copper foil having a core wire diameter of 0.08 mm or less rolled to 1/4 or less of the wire diameter around a meta aramid fiber having a center yarn of 30th single yarn or less. A set of 13 wires and a flat knitted fabric with a thickness of 0.58 mm or less is used.
[0017]
That is, the conventional tinsel wire uses, for example, a copper foil formed by rolling a copper wire having a core wire diameter of about 0.1 mm around a meta-aramid fiber having a twist of 40 center yarns. Has a drawback that it is difficult to obtain a desired damper performance because of a thickness of about 0.72 mm.
[0018]
In the present invention, the flat knitted tinsel wire 5 is formed into a thin band shape in which ultrafine single wires are assembled into a flat knitting.
[0019]
When the tinsel wire is thinned in this way, the adhesion between the mold gap and the damper cloth material during the molding of the damper is improved, so that the shape of the corrugation 2 is stable and the performance as the damper 1 is not impaired. Furthermore, if the thickness of the flat knitted tinsel wire 5 is thin, the bending performance by vibration is improved, so that the durability is also improved.
[0020]
As described above, the flat knitted bronze wire 5 employs a flat knitted structure thinner than that conventionally used. Therefore, the flat knitted wire 5 is excellent in flexibility and does not impair the damper performance, thereby obtaining good performance. be able to.
