Abstract
(57)【要約】
【目的】 ボイスコイル・ボビンの比強度を増大させる
こと。
【構成】 ボイスコイル・ボビン１は、内面にハニカム

(57) [Summary] [Purpose] To increase the specific strength of the voice coil bobbin. [Structure] The voice coil bobbin 1 has a honeycomb-shaped unevenness 2 formed on the inner surface thereof.
Description
【０００１】[0001]
本考案は、ボイスコイル・ボビンに関し、さらに詳しく言えば、内面にハニカ ム形状の凹凸を形成したボイスコイル・ボビンに関するものである。 TECHNICAL FIELD The present invention relates to a voice coil bobbin, and more particularly to a voice coil bobbin having an inner surface having a honeycomb-shaped unevenness.
【０００２】[0002]
従来、スピーカ等に用いられるボイスコイル・ボビンは、紙、アルミニウム箔 、合成樹脂フィルム、ガラス複合材料フィルム等を素材としてつくられている。 これらの素材は、いずれも軽くて丈夫であることが条件とされる。 Conventionally, voice coils and bobbins used for speakers and the like are made of paper, aluminum foil, synthetic resin film, glass composite material film and the like. All of these materials are required to be light and durable.
【０００３】 しかし、これらの素材は、強度上、一定以下の厚さに製造することはできない 。However, these materials cannot be manufactured to have a certain thickness or less in terms of strength.
【０００４】[0004]
本考案は、ボイスコイル・ボビン用の素材をできるだけ薄くして軽くするとと もに比強度（単位重量当りの強度）を増大させることを課題にしている。 It is an object of the present invention to make the material for the voice coil bobbin as thin and light as possible and to increase the specific strength (strength per unit weight).
【０００５】[0005]
本考案のボイスコイル・ボビンは、内面にハニカム形状の凹凸を形成すること によって、上記課題を解決している。 The voice coil bobbin of the present invention solves the above problem by forming honeycomb-shaped irregularities on the inner surface.
【０００６】[0006]
ハニカム形状の凹凸が素材を強化することができるので、素材を薄くつくるこ とができる。 Honeycomb-shaped irregularities can strengthen the material, making it possible to make the material thin.
【０００７】[0007]
図１−３を参照して、本考案のボイスコイル・ボビンの実施例について説明す る。 An embodiment of the voice coil bobbin of the present invention will be described with reference to FIGS.
【０００８】 図１，２に示すように、本考案のボイスコイル・ボビン１は、内面にハニカム 形状の凹凸２を形成した構造になっている。図２はボイスコイル・ボビン１を展 開して拡大したものである。凹凸２は六角形の周辺を凹にそして六角形の中央部 を凸に形成する。その逆に形成してもよい。As shown in FIGS. 1 and 2, the voice coil bobbin 1 of the present invention has a structure in which honeycomb-shaped irregularities 2 are formed on the inner surface. Figure 2 shows the expanded voice coil bobbin 1. The unevenness 2 forms a concave portion around the hexagon and a convex central portion of the hexagon. It may be formed in reverse.
【０００９】 例えば、素材厚さ６０μmの場合、凹部の深さを３０μmとし、六角形の一辺を ２mm程度にすることが好ましい。For example, when the material thickness is 60 μm, it is preferable that the depth of the recess is 30 μm and the side of the hexagon is about 2 mm.
【００１０】 六角形のハニカム形状は、製造が容易であり、凹部に方向性が生じないので強 度上も好ましい。 図３は、本考案のボイスコイル・ボビン１の製造過程を示す。The hexagonal honeycomb shape is easy to manufacture and has no directionality in the recesses, and is therefore preferable in terms of strength. FIG. 3 shows a manufacturing process of the voice coil bobbin 1 of the present invention.
【００１１】 例えば、ゲル状の合成樹脂フィルムの素材３を、平板の金型４と、ハニカム形 状の凹凸部５を有する金型５との間に置いて、加熱しながら加圧し、素材３の片 面にハニカム形状の凹凸を形成する。For example, the gel-like synthetic resin film material 3 is placed between a flat plate mold 4 and a mold 5 having a honeycomb-shaped concave-convex portion 5, and is pressed while being heated. Honeycomb-shaped irregularities are formed on one surface of the.
【００１２】 アルミニウム箔等の場合には、一方のロール表面にハニカム形状の凹凸部を形 成した１対の圧延ロール間を通すことによって、アルミニウム箔の片面に凹凸を 形成することができる。In the case of an aluminum foil or the like, it is possible to form irregularities on one side of the aluminum foil by passing it between a pair of rolling rolls having a honeycomb-shaped irregular portion formed on the surface of one roll.
【００１３】[0013]
本考案によれば、素材の固有の比強度を、片素にハニカム形状の凹凸形状にす るだけで向上させることができ、スピーカの音質を改善でき、内面の表面積の増 大によりボイスコイル・ボビンの放熱効果を上げることができる。 According to the present invention, the specific strength of the material can be improved only by making the honeycomb-shaped uneven shape in one piece, the sound quality of the speaker can be improved, and the surface area of the inner surface can be increased to improve the voice coil. The heat dissipation effect of the bobbin can be improved.
