Description
【０００１】[0001]
本考案は、電気音響変換器におけるスピーカ、特に楕円形スピーカに関する。 The present invention relates to a speaker in an electroacoustic transducer, particularly an elliptical speaker.
【０００２】[0002]
従来における代表的な楕円形スピーカは、内磁型或いは外磁型の磁気回路と、 この磁気回路に固着されるスピーカフレームと、ボイスコイルが巻着され、前記 磁気回路の磁気ギャップ内に配置されるボイスコイルボビンと、このボイスコイ ルボビンに内周縁が固着され外周縁がスピーカフレームに固着されてボイスコイ ルボビンを支持するダンパーと、内周縁が前記ボイスコイルボビンに固着され、 外周縁がエッジを介してスピーカフレームに固着される楕円形振動板と、当該楕 円形振動板の略中央に前記ボイスコイルボビンを覆うように固着されるダストキ ャップとにより構成され、前記ダンパーには布製の円形コルゲーションダンパー が多用されている。 In a typical conventional elliptical speaker, an inner magnet type or an outer magnet type magnetic circuit, a speaker frame fixed to this magnetic circuit, and a voice coil are wound around and placed in the magnetic gap of the magnetic circuit. A voice coil bobbin, a damper for supporting the voice coil bobbin with an inner peripheral edge fixed to the voice coil bobbin and an outer peripheral edge fixed to the speaker frame, an inner peripheral edge fixed to the voice coil bobbin, and an outer peripheral edge fixed to the speaker frame via an edge. A circular corrugation damper made of cloth is often used for the damper, which is composed of an elliptical diaphragm that is fixed to the oval diaphragm, and a dust cap that is fixed to approximately the center of the oval circular diaphragm so as to cover the voice coil bobbin. ..
【０００３】[0003]
この様な構造を有する従来の楕円形スピーカは、エッジと楕円形振動板との結 合部において、楕円形振動板の振幅が、短径側の方が長径側と比較して大きくな り、短径側のエッジに、より大きな変形ストレスがかかるため、振動板を一様に 支持するのが難しく、ローリングや振動板にねじれを生じる、という解決すべき 課題があった。 In the conventional elliptical speaker having such a structure, the amplitude of the elliptical diaphragm becomes larger on the minor axis side than on the major axis side at the joint between the edge and the elliptical diaphragm. Since the larger deformation stress is applied to the edge on the minor axis side, it is difficult to support the diaphragm uniformly, and there is a problem to be solved that the rolling and the diaphragm are twisted.
【０００４】 そこで本考案は、上記従来例に付する欠点を解消し、短径側のエッジに長径側 と比較し、より大きな変形ストレスがかかること無く、ローリングやねじれを生 じない楕円形スピーカを提供することを目的とする。Therefore, the present invention solves the above-mentioned drawbacks of the conventional example, and compared with the long diameter side, the edge on the short diameter side is not subjected to greater deformation stress, and does not cause rolling or twisting. The purpose is to provide.
【０００５】[0005]
上記目的を達成するための本考案に係る楕円形スピーカは、楕円形振動板を有 し、且つ支持部材に円形のダンパーを用いた楕円形スピーカにおいて、前記楕円 形振動板1 の短径側のダンパー2 の一部に、緩衝材11が固着されたことを特徴と し、 または、楕円形振動板を有し、且つ支持部材に円形のダンパーを用いた楕円形 スピーカにおいて、一端が前記楕円形振動板1 の短径側のダンパー2 の一部に、 他端が磁気回路側に固着された緩衝材11を有することを特徴とし、 または、楕円形振動板を有し、且つ支持部材に円形のダンパーを用いた楕円形 スピーカにおいて、一端が前記楕円形振動板1 の短径側のダンパー2 の一部に固 着された第１緩衝材11a と、一端が磁気回路側の前記第１緩衝材11a と略重なる 略同位置に固着された第２緩衝材11b とを有し、前記第１緩衝材11a と前記第２ 緩衝材11b との間に粘着性を有する粘性体12が挟着されたことを特徴とする。 The elliptical speaker according to the present invention for achieving the above object is an elliptical speaker having an elliptical diaphragm and using a circular damper as a supporting member. A cushioning material 11 is fixed to a part of the damper 2, or an elliptical speaker having an elliptical diaphragm and a circular damper as a supporting member is provided with one end of the elliptical shape. One of the dampers 2 on the minor axis side of the diaphragm 1 is characterized by having a cushioning material 11 having the other end fixed to the magnetic circuit side, or an elliptical diaphragm and a circular support member. In an elliptical speaker using the above damper, one end of the elliptical diaphragm 1 is fixed to a part of the damper 2 on the short diameter side of the elliptical diaphragm 1 and the other end of the first cushion is located on the magnetic circuit side. Second cushioning material 11b fixed at substantially the same position as material 11a It has a viscous body 12 having an adhesive property is characterized by being sandwiched between the second cushioning member 11b and the first cushioning member 11a.
【０００６】[0006]
楕円形振動板1 の短径側のダンパー2 の一部に緩衝材11を固着することにより 、ダンパー2 の緩衝材11が付加された部分のスティフネスが大きくなるため、楕 円形振動板1 の短径側の振動が制動される。また、緩衝材11を固着することによ りダンパー2 に機械的損失が付与されて、ダンパー2 の音響放射が抑えられる。 By fixing the cushioning material 11 to a part of the damper 2 on the minor axis side of the elliptical diaphragm 1, the stiffness of the portion of the damper 2 to which the cushioning material 11 is added becomes large. Vibration on the radial side is damped. Further, by fixing the cushioning material 11, a mechanical loss is imparted to the damper 2 and the acoustic emission of the damper 2 is suppressed.
【０００７】 更に、楕円形振動板1 の短径側のダンパー2 と磁気回路側との間に緩衝材11を 固着することにより、より大きな楕円形振動板1 の短径側の制動が得られる。Further, by fixing a cushioning material 11 between the damper 2 on the minor axis side of the elliptical diaphragm 1 and the magnetic circuit side, a larger braking on the minor axis side of the elliptical diaphragm 1 can be obtained. ..
【０００８】 更に、一端が楕円形振動板1 の短径側のダンパー2 の一部に固着された第１緩 衝材11a と、一端が磁気回路側の前記第１緩衝材11a と略重なる略同位置に固着 された第２緩衝材11b と、第１緩衝材11a と第２緩衝材11b との間に粘着性を有 する粘性体12が挟着された構造では、第１緩衝材11a と第２緩衝材11b と粘性体 12との間で滑り摩擦を生じ、これにより大きな機械的損失がダンパー2 に付与さ れ、また、短径側の楕円形振動板の制動を所望に制御することが可能になる。Further, one end of the first cushioning material 11a fixed to a part of the damper 2 on the short diameter side of the elliptical diaphragm 1 and one end of the first cushioning material 11a on the magnetic circuit side substantially overlap with each other. In the structure in which the second cushioning material 11b fixed at the same position and the viscous material 12 having adhesiveness are sandwiched between the first cushioning material 11a and the second cushioning material 11b, Sliding friction is generated between the second shock absorbing material 11b and the viscous body 12, which causes a large mechanical loss to the damper 2 and also the desired control of the braking of the elliptical diaphragm on the minor axis side. Will be possible.
