Description
【発明の詳細な説明】 〔発明の利用分野〕 本発明は、スピーカに関する。[Detailed description of the invention] [Field of application of the invention] The present invention relates to a speaker.
第1図、第2図は従来技術の振動板を示す。 1 and 2 show a prior art diaphragm.
第2図中芯材1、フェース材2は別々のピースを後工程

カム材を芯材に用いた場合、これにコルゲーションをつ
けることは、さらに難しい。In FIG. 2, the core material 1 and the face material 2 are separate pieces that are assembled using adhesive in a subsequent process. Therefore, it is difficult to attach corrugations to this due to the dimensional accuracy of each component or the strength of the face material 20. Furthermore, when nicum wood is used as the core material, it is even more difficult to attach corrugations to it.
本発明の目的は、上記従来技術の欠点をなくし、安価で
かつ剛性が高く軽量な振動板を持つスピーカを提供する
ことにある。SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the prior art described above and to provide a speaker having a diaphragm that is inexpensive, highly rigid, and lightweight.
本発明の要点は芯材に発泡材を用い成形時にフェース材
と共にコルゲーションをつけることにより、安価で軽量
高剛性の振動板を用いたスピーカを実現させることにあ
る。The main point of the present invention is to realize a speaker using a diaphragm that is inexpensive, lightweight, and highly rigid by using a foamed material for the core material and adding corrugations together with the face material during molding.

ション3をつける。FIGS. 3 and 4 show an embodiment of a diaphragm according to the present invention. The core material 1 is a foam material, and is foam-molded together with the face material 2. At this time, corrugations are attached to the mold, and corrugations 3 are attached to the diaphragm consisting of the core material 1 and the face material 2 at the same time as the foam molding.

の振動板にも適用できる。Note that the corrugation 5 does not have to be a circle as shown in Figure 3.
As shown in FIG. 5, FIG. 6, and FIG. 7, the shape may be elliptical or torpedo-shaped in the radial direction, or it may be spiral-shaped although not shown in the figures. A combination of these may also be used. Furthermore, it may be double-sided or single-sided. Furthermore, these can be applied not only to flat plates but also to cone-shaped diaphragms.
以上の振動板を用いれば、安価で軽量高剛性の性能の良
いスピーカを得ることができる。By using the above diaphragm, it is possible to obtain an inexpensive, lightweight, highly rigid speaker with good performance.
