要とする欠点を有するとともに、ハニカムコア１と表面
材３、４との接着が線接着で−あり、ハニカムコア１と
表面材３、４との力学的強度が弱い欠点がある。However, the diaphragm using the honeycomb core 1 described above is
The honeycomb core 1 itself has the disadvantage of requiring many processes to manufacture, and the bond between the honeycomb core 1 and the surface materials 3 and 4 is line bonding, and the honeycomb core 1 and the surface materials 3 and 4 are bonded together by line bonding. The disadvantage is that the mechanical strength is weak.
本発明は上記従来の欠点を除去するものであり、以下
に本発明の一実施例について第２図〜第５図とともに説

で容易に製造でき、また完成した振動板は軽くて大きな
剛性を有し、本発明振動板を用いたスピーカはピストン
振動領域が広くなるものである。さらに本発明振動板は
骨格材と表面材とが面接着されるため従来のハニカムコ
アを用いた振動板に比較して強度が向上するものである
。特に骨格材の突起同志がその側面で接触するようにし
た場合には横方のズレに対して強くなり、剛性が向上す
る利点を有するものてある。As shown in Fig. 3, two pieces of this skeleton body 7, 7' are placed opposite each other
The protrusion 6 of one skeletal body 7 is the protrusion 6 of the other skeletal body 7'.
The skeletal bodies 7, 7' are superimposed so as to be located between them, and the skeletal bodies 7, 7' are integrated by bonding or welding, and as shown in FIG. (Fig. 4, Fig. 5).In the above embodiment, the protrusions 6, 6' of the skeleton bodies 7, 7' are attached to the protrusions 6, 7'.
It is preferable to form the 6' sides so that they are in contact with each other. Further, the shapes of the projections 6, 6' of the skeleton bodies 7, 7' are as follows:
It may be of any shape, such as a cylindrical shape, a Ξ-gonal shape, or a hexagonal shape. The present invention has the above-mentioned structure, and can be easily manufactured by simply superimposing and bonding the skeleton bodies in which protrusions are formed on metal foil, and bonding flat surface materials to both sides of the joined flat skeleton bodies. Furthermore, the completed diaphragm is light and has great rigidity, and a speaker using the diaphragm of the present invention has a wide piston vibration area. Furthermore, the diaphragm of the present invention has improved strength compared to a diaphragm using a conventional honeycomb core because the framework material and the surface material are bonded surface to surface. Particularly, when the protrusions of the frame material are brought into contact with each other on their side surfaces, the structure has the advantage of being resistant to lateral displacement and improving rigidity.
