【考案の詳細な説明】
この考案はスピーカのボイスコイルボビンの改良に関す
るものである。[Detailed Description of the Invention] This invention relates to an improvement of a voice coil bobbin for a speaker.
従来のスピーカ用ボイスコイルボビン（以下ボビンとい
う）は、紙、アルミニウム、合成樹脂等で構成されてお
り、ボビンの個所を全く空気が流通しないために、第１
図に示すようにその周囲に大きな空気抜き孔５を形成し
、ボイスコイル内の空気圧を減少させ、熱せられた空気
を逃がすとともにボイスコイルユニット全体を軽量化し
ていたものである。Conventional speaker voice coil bobbins (hereinafter referred to as bobbins) are made of paper, aluminum, synthetic resin, etc., and because no air flows through the bobbin, the first
As shown in the figure, a large air vent hole 5 is formed around the voice coil to reduce the air pressure inside the voice coil, allow heated air to escape, and reduce the weight of the entire voice coil unit.
しかしながら、このような従来のボビンにおいては、空
気抜き量（放熱量）を上げようとするとボビン自体の強
度が下がり、また、ボビンの強度を上げようとすると放
熱効果等が悪化するという欠点があった。However, such conventional bobbins have the disadvantage that if you try to increase the amount of air removed (heat dissipation amount), the strength of the bobbin itself decreases, and if you try to increase the strength of the bobbin, the heat dissipation effect deteriorates. .
この考案においては上述した従来の欠点をなくしたボビ
ンを提供することを目的とするものである。The object of this invention is to provide a bobbin that eliminates the above-mentioned conventional drawbacks.
以下図面に示す実施例に基づいてこの考案を説明する。This invention will be explained below based on embodiments shown in the drawings.
第２図Ａはこの考案の一実施例であり、振動板、磁気回
路等はこの考案の主要部とはならないので省略し、ボイ
スコイル部分のみを示しである。FIG. 2A shows an embodiment of this invention, and since the diaphragm, magnetic circuit, etc. are not the main parts of this invention, they are omitted and only the voice coil portion is shown.
図中１はボビン、２はボイスコイル、３はリード線４を
固定する紙帯である。In the figure, 1 is a bobbin, 2 is a voice coil, and 3 is a paper band for fixing a lead wire 4.
ボビン１は非磁性ステンレス材等の薄板にフォトエツチ
ングによる微小孔６を多数均一に穿設したものであり、
その板厚はＱ、３ｍｍ程度までなら自由に選択でき、微
小孔６の形状、数量等も第２図Ｂに示すように自由に選
定し得るものである。The bobbin 1 is a thin plate made of non-magnetic stainless steel material, etc., in which a large number of micro holes 6 are uniformly bored by photo-etching.
The plate thickness Q can be freely selected up to about 3 mm, and the shape, number, etc. of the microholes 6 can also be freely selected as shown in FIG. 2B.
従って、斯る構成によるボビンにおいては開口率を７割
近くにすることができ、スピーカとして動作させた場合
、該ボビンからは空気が容易に抜けることになるのであ
る。Therefore, in the bobbin having such a configuration, the aperture ratio can be made close to 70%, and when the bobbin is operated as a speaker, air can easily escape from the bobbin.
また、開口率を高くするために非磁性ステンレス等の強
度が高く重い材料を用いたとしても多数の穿設された微
小孔によってアルミニウムと同じくらいの重量にでき、
しかも強度はアルミニウムよりも高くできる。In addition, even if a strong and heavy material such as non-magnetic stainless steel is used to increase the aperture ratio, it can be made to have the same weight as aluminum due to the large number of micro holes.
Moreover, it can be stronger than aluminum.
更に非磁性ステンレス等の金属によって構成されるため
に熱伝導性が良く、耐熱性も良くなるので、商人カスピ
ー力等に用いることができる等の効果を有するものであ
る。Furthermore, since it is made of a metal such as non-magnetic stainless steel, it has good thermal conductivity and good heat resistance, so it has the advantage of being able to be used for merchant Caspie force, etc.
