【発明の詳細な説明】
〈産業上の利用分野〉
本発明は蛇腹状に構成されたスピーカ用エツジに関する
ものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a speaker edge configured in a bellows shape.
〈従来の技術〉
スピーカ用エツジとしては、従来からロールエツジやフ
ィックスエツジなどが知られているが、いずれも振動板
の周縁からその外周方向に向かって拡がるリング状のも
のであり、エツジの外径は一般に実際の振動板の外径よ
りもかなり大きな寸法となるのが普通である。<Prior Art> Roll edges and fixed edges have been known as speaker edges, but both are ring-shaped that expands from the periphery of the diaphragm toward its outer circumference. is generally much larger than the outer diameter of the actual diaphragm.
〈発明が解決しようとする問題点〉
上記のように、従来は振動板の外周に外径の大きなエツ
ジがあるため、完成したスピーカを正面から見た場合、
全体の面積の４０〜５０％がエツジやフレームなど振動
板以外の部分で占められる結果となり、スピーカが大形
化し、一定の大きさのスピーカボックスに取付は可能な
スピーカの口径が小さくなり、あるいはスピーカボック
スが大きくなるという問題が生じている。<Problems to be Solved by the Invention> As mentioned above, conventional diaphragms have edges with a large outer diameter on the outer periphery, so when a completed speaker is viewed from the front,
As a result, 40 to 50% of the total area is occupied by parts other than the diaphragm, such as edges and frames, resulting in larger speakers, and the diameter of speakers that can be installed in a speaker box of a certain size becomes smaller, or A problem arises in that the speaker box becomes larger.
本発明はこのような問題点に着目し、エツジの正面から
見た面積を小さくすることを課題としてなされたもので
ある。The present invention has been made with attention to such problems and an object of the present invention is to reduce the area of the edge when viewed from the front.
く問題点を解決するための手段〉
上記の課題を達成するため、本発明ではスピーカ用エツ
ジを軸方向に伸縮可能なように蛇腹状に構成している。Means for Solving the Problems> In order to achieve the above-mentioned problems, in the present invention, the speaker edge is constructed in a bellows shape so that it can be expanded and contracted in the axial direction.
く作用〉
本発明のエツジは、蛇腹状であって振動板の外周方向に
拡がる形状でないため、正面から見た面積が小さく、ス
ピーカの小形化が可能となる。Effects> Since the edges of the present invention are bellows-shaped and do not expand in the outer circumferential direction of the diaphragm, the area when viewed from the front is small, and the speaker can be made smaller.
〈実施例〉 次に１図面に示した本発明の実施例について説明する。<Example> Next, an embodiment of the present invention shown in one drawing will be described.
第１図は一実施例のエツジを用いたスピーカの断面図で

面を振動板（２）の外周に接着し。FIG. 1 is a sectional view of a speaker using an edge according to an embodiment, and in the figure, (1) is an edge according to the present invention, and (2) is a sectional view of a speaker using an edge.
) is the diaphragm, (3) is the frame, (4) is the damper, (
5) is a voice coil, and (6) is a magnet. The edge (1) is bellows-shaped with three arc-shaped folded parts (1a), and has a short cylindrical shape as a whole, and its front end surface is adhered to the outer periphery of the diaphragm (2).
後端面をフレーム（３）の外周に接着しである。The rear end surface is glued to the outer periphery of the frame (3).
本実施例のエツジ（１）はこのように構成されており、
蛇腹状であるため軸方向に伸縮可能で振動板（２）の振

徴があり、全体の面積に対する振動板（２）の面積の比
率を大幅に向上することができるのである。The edge (1) of this example is configured as follows,
Since it is bellows-shaped, it can be expanded and contracted in the axial direction, allowing the diaphragm (2) to vibrate freely, and has a certain strength in the direction perpendicular to the axis, so it reliably supports the diaphragm (2). In addition, its functions are completely the same as conventional edges, such as no ventilation, and it has all the characteristics that edges should have, but it also has the characteristic that the surface area when viewed from the front is extremely small compared to conventional edges. The ratio of the area of the diaphragm (2) to the overall area can be greatly improved.
第２図はこの関係を説明する図であり、同一のフレーム
（３）に本実施例のエツジ（１）を用いて振動板（２）

。Ａ、Ｂ、Ｃはそれぞれフレーム（３）。FIG. 2 is a diagram explaining this relationship, in which the edge (1) of this example is used on the same frame (3), and the diaphragm (2) is mounted on the same frame (3).
The case where the diaphragm (12) is attached using the edge (11) of the conventional example is illustrated by the broken line. A, B, and C are each frames (3).
振動板（２）、振動板（１２）の直径であり、この図の
場合、Ａ：Ｂ：Ｃの比率は１００ ： ８７ ： ６９
であって、面積比では１００ ： ７６ ： ４８とな
っており、振動板（２）と振動板（１２）の面積比は７
６／４８＝ １．５８となり、５８％増と大幅に増加し
ていることがわかる。この数字はやや極端な例であるが
、同一の外径のスピーカで振動板の面積を従来より３０
〜４５％程度大きくすることは極めて容易である。These are the diameters of the diaphragm (2) and diaphragm (12), and in the case of this figure, the ratio of A:B:C is 100:87:69.
The area ratio is 100:76:48, and the area ratio of diaphragm (2) and diaphragm (12) is 7.
6/48 = 1.58, which shows a significant increase of 58%. Although this figure is a somewhat extreme example, the area of the diaphragm is 30% smaller than that of conventional speakers with the same outer diameter.
It is extremely easy to increase the size by about 45%.
エツジ（１）の材料としては、従来からエツジ材として
用いられているものであれば理論的にはすべて使用可能

できる。As for the shape of the edge (1), the cross-sectional shape of the folded part (la) may be an arc shape as shown in FIG. The folded part (1a) is free from one piece to an appropriate number of pieces.
The shape and number of the diaphragms can be changed as appropriate, and the overall shape when viewed from the front is not limited to a circle, but can be an ellipse, a square, or any other shape that is suitable for the diaphragm that is combined.

ーカに用いれば特に効果がある。Although it has all the characteristics that an edge should have, it has a feature that its surface area when viewed from the front is significantly smaller. Therefore, the diameter of the diaphragm can be made larger than in the past compared to the external dimensions of the entire speaker, and if the diaphragm has the same dimensions, the speaker box that can be attached will be smaller; On the other hand, it becomes possible to install a speaker with a larger diaphragm than before. Incidentally, in recent years, rectangular speakers have been manufactured in order to improve the space factor when installed in a speaker box.1 The edge of the present invention is effective in improving the space factor; It is particularly effective when used in speakers.
