ーカに関するものである。[Detailed description of the invention] This invention consists of firmly attaching an aluminum cap to the lower surface of a flat diaphragm sandwiched between surface materials with a honeycomb core as the center core, and attaching a voice coil bobbin to the aluminum cap. The present invention relates to a flat speaker with increased input resistance.
従来、第１図に示すごとく、センターポール１２、マグ

イル７を中心に保持する。Conventionally, as shown in FIG. 1, a center pole 12, a magnet 13, and a plate 14 constitute a magnetic circuit, and the center pole 12 and plate 14 form a magnetic gap.
The frame 15 is attached to the upper surface of the plate 14, the voice coil 70 winding part is arranged at the center of the magnetic gap, and the frame 1
The voice coil 7 is held at the center by a damper 16 whose outer peripheral edge is attached to the inner bottom of the damper 5.
繊維質材料のシートで形成された平板状・・ニカムコア
ーの両面に繊維質材料の表面材を貼着せる振動板８の下
面にボイスコイル７のボビン上端を貼着し、振動板８の
外周縁に断面円弧形環状のエツジ１１の内周縁を貼着し
、エツジ１１の外周縁をフレーム１５の外周縁に貼着し
ていた。The upper end of the bobbin of the voice coil 7 is attached to the lower surface of the diaphragm 8, and the upper end of the bobbin of the voice coil 7 is attached to the lower surface of the diaphragm 8. The inner circumferential edge of the edge 11 having an annular arcuate cross section was attached, and the outer circumferential edge of the edge 11 was attached to the outer circumferential edge of the frame 15.
この場合、ボイスコイルボビンの運動方向に対して振動
板８の表面材を押し曲げる構造となっている為に表面材
の表面にシワが入り弱い、又表面材とボイスコイルボビ
ンとは運動方向により、剥離力が働き、接着面積が少い
ので接着力が弱くなる欠点があった。In this case, since the surface material of the diaphragm 8 is pressed and bent in the direction of motion of the voice coil bobbin, the surface material may wrinkle easily, and the surface material and the voice coil bobbin may separate depending on the direction of motion. There was a drawback that the adhesive force was weak because the adhesive force was small and the adhesive area was small.
その為に第２図に示すごとく、平板ハニカム振動板９の
中央孔に帽子状アルミニウムキャップ１０を挿入貼着し
、アルミニウムキャップ１０の外周下面にボイスコイル
７のボビン上端を貼着していた。For this purpose, as shown in FIG. 2, a cap-shaped aluminum cap 10 is inserted into the center hole of the flat honeycomb diaphragm 9 and is attached, and the upper end of the bobbin of the voice coil 7 is attached to the lower outer circumference of the aluminum cap 10.
この場合振動板９とアルミニウムキャップ１０との接着
力は強化されるが、アルミニウムキャップ部分が中空の
為に・・ニカム構造材に入部ができて、振動板９か弱く
なる。In this case, the adhesive force between the diaphragm 9 and the aluminum cap 10 is strengthened, but since the aluminum cap portion is hollow, the diaphragm 9 is weakened because it enters the nicum structural material.
アルミニウムキャップ１０にハニカムコア一部と同様の
剛性を与える為にアルミニウムキャップ１０の肉厚を厚
くすると重量が増加して、軽くて剛性が大きいハニカム
振動板の特長が損なわれる欠点があった。If the thickness of the aluminum cap 10 is made thicker in order to give the aluminum cap 10 the same rigidity as a part of the honeycomb core, the weight increases, which has the disadvantage that the advantages of the honeycomb diaphragm, which is light and rigid, are lost.
本考案は上記欠点を取除く為に考案されたもので、図面
に示す実施例について説明すれば第３図に示すごとく、
磁気回路、フレーム、ボイスコイル、ダンパーの関係位
置は従来例と同じである。The present invention was devised to eliminate the above-mentioned drawbacks, and the embodiment shown in the drawings will be explained as shown in Fig. 3.
The relative positions of the magnetic circuit, frame, voice coil, and damper are the same as in the conventional example.
熱可塑性合成樹脂繊維単独又は天然パルプ繊維との混抄
紙で形成された平板状・・ニカムコア−２の両面に前記
材料の表面材３を貼着せる振動板１の下面に環状加熱金
型を押圧して、溶融させて環状溝４を形成する。A ring-shaped heating mold is pressed onto the lower surface of the diaphragm 1 to which the surface material 3 of the above-mentioned material is pasted on both sides of the Nicum core 2, which is a flat plate made of paper made of thermoplastic synthetic resin fibers alone or mixed with natural pulp fibers. Then, the annular groove 4 is formed by melting.
環状溝４に接着剤６を流し込み、皿状アルミニウムキャ
ップ５の外周端を挿入し、さらに接着部にもう一度接着
剤６を塗布して、溝４に接着剤６を充填させる。The adhesive 6 is poured into the annular groove 4, the outer peripheral end of the dish-shaped aluminum cap 5 is inserted, and the adhesive 6 is applied once again to the adhesive part to fill the groove 4 with the adhesive 6.
前記アルミニウムキャップ５の下面にボイスコイル７の
ボビン上端ヲ貼着し、振動板１の外周縁に断面円弧形環
状のエツジ１１の内周縁を貼着し、エツジ１１の外周縁
をフレーム１５の外周縁に貼着せる平板スピーカである
。The upper end of the bobbin of the voice coil 7 is attached to the lower surface of the aluminum cap 5, the inner circumference of an edge 11 having an annular arcuate cross section is attached to the outer circumference of the diaphragm 1, and the outer circumference of the edge 11 is attached to the outer circumference of the frame 15. It is a flat speaker that is attached to the outer periphery.
本考案は上記のような構造になっているので、振動板１
とアルミニウムキャップ５、アルミニウムキャップ５と
ボイスコイル７のボビン上端との接着部の強度を飛躍的
に増すことができ、かつ、ボイスコイルボビン上端部に
アルミニウムキャップが接着されているのでボイスコイ
ルからのジュール熱の放熱効果を増大して、スピーカの
耐入力を上昇させるものである。Since the present invention has the above structure, the diaphragm 1
The strength of the bond between the aluminum cap 5 and the upper end of the bobbin of the voice coil 7 can be dramatically increased, and since the aluminum cap is bonded to the upper end of the voice coil bobbin, the joules from the voice coil can be increased dramatically. This increases the heat dissipation effect and increases the input resistance of the speaker.
