本発明はダブルコーンスピーカに用いるスピーカのサブ
コーンに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a speaker subcone used in a double cone speaker.
従来の技術
従来この種のダブルコーンスピーカのサブコーンは、第
３図の様な構造になっていた。すなわち１つのボイスコ

駆動して、高音域ではサブコーン４のみが駆動されるよ
うになっているスピーカがある。Prior Art Conventionally, the subcone of this type of double cone speaker had a structure as shown in FIG. That is, there is a speaker in which one voice coil 1 drives both a horn 2 with edges 3 and a round subcone 4, and only the subcone 4 is driven in the high frequency range.
発明が解決しようとする問題点
ところが、前者のダブルコーンの構成で、スピーカとし

ップを生じる問題が発生する。フルレンジスピーカとし
て音質上好ましくない問題があった。Problem to be Solved by the Invention However, when the former double cone configuration is driven as a speaker, the main cone and sub-cone have concentric shapes, so the sound emitted from the back surface of the sub-cone is The sound is reflected from the cone and interferes with the sound from the front of the sub-cone, causing a sharp resonance due to the sound pressure frequency characteristics and the connection between the main cone and the sub-cone, resulting in a sharp dip. As a full-range speaker, there were problems with the sound quality.
そこで本発明は、この鋭い共撮の発生を防止しスムーズ
な周波数特性を有するフルレンジスピーカを提供するも
のである。Therefore, the present invention provides a full-range speaker that prevents the occurrence of sharp co-photography and has smooth frequency characteristics.

この問題を解決するために、本発明は、サブコーンの外
径形状を長円形状にすると同時に、ボイスコイルと貼付
ける中心孔と外径を非対称にしたサブコーンをボイスコ
イルに貼付けるものである。In order to solve this problem, the present invention makes the outer diameter of the sub-cone an oval shape, and at the same time makes the outer diameter of the sub-cone asymmetrical with respect to the center hole to which it is attached to the voice coil. It is attached to the coil.

径の比率等で、指向性制御もでき、スピーカの取付位置
と受聴点の方向で、制御することもできる特徴がある。Due to the combination of the sub-cone, which is asymmetrical and has an oval shape, and the round-shaped main cone, the sound emitted from the back of the sub-cone is reflected from the main cone, and the interference with the sound from the front of the sub-cone becomes unbalanced. Due to the sound pressure frequency characteristics, sharp resonance does not occur and a smooth response is obtained. Even in terms of appearance, it can change the image of conventional double cone speakers. Furthermore, the directivity can be controlled by adjusting the ratio of the short axis to the long axis of the elliptical shape, and can also be controlled by the mounting position of the speaker and the direction of the listening point.
実施例
以下本発明の一実施例におけるスピーカのサブコーンに
ついて説明する。EXAMPLE A subcone of a speaker in an example of the present invention will be described below.
第１図ａ、ｂ、第２図ａ、ｂに示す。内径７より径大な
る長円６形状を有する円すい形状で、且つ、内径と楕円
外径は非対称ａ＜ｂ形状を有するサブコーン６である。It is shown in FIG. 1 a, b and FIG. 2 a, b. The sub-cone 6 has a conical shape with an ellipse 6 having a diameter larger than the inner diameter 7, and has an asymmetrical a<b shape between the inner diameter and the elliptical outer diameter.
このサプコー７４を第２図のように、ボイスコイル１に
エツジ３付メインコーン２とサブコーン６を貼付けてな
る構造を有するダブルコーンスピーカである。As shown in FIG. 2, this subcone 74 is a double cone speaker having a structure in which a main cone 2 with an edge 3 and a subcone 6 are attached to a voice coil 1.

サブコーンの音の干渉全ブロードにすることができ、音
圧周波数特性上、鋭いディップのないスムーズなレスポ
ンスが得られる。Effects of the Invention As described above, the present invention, by combining the asymmetrical elliptical subcone and the conical main cone, can make the interference between the main cone and the subcone completely broad, and can eliminate sharp dips in sound pressure frequency characteristics. You will get a smooth response.
又、サブコーンの形状が長円であり、長径、短径の比率

聴点を考慮した新しい形のダブルコーンスピーカを提供
することができ、実用価値大である。In addition, the shape of the sub-cone is an ellipse, and the directional characteristics can be fully controlled by the ratio of the major axis and minor axis, making it possible to provide a new type of double cone speaker that takes into account mounting conditions and listening points, and has practical value. It's large.
