Abstract

PURPOSE:To realize a speaker using an inexpensive diaphragm light in weight and high in rigidity by using a foaming member to a core member and applying corrugation together with a face member at forming. CONSTITUTION:The core member 1 is formed by foaming a foaming member together with the face member 2. In this case, corrugation is applied to a mold so as to apply corrugation 3 to the diaphragm comprising the core member 1 and the face member 2 at the same time of foaming. Further, the corrugation 3 can be circular, radial, elliptic, comma-shaped or spiral form.

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.

〔発明の背景〕[Background of the invention]

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.

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.

〔発明の目的〕[Purpose of the invention]

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.

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.

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.

〔発明の効果〕〔Effect of the invention〕

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.
