産業上の利用分野
本発明は、一般音響機器に適用される角形スピーカの振
動板に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a diaphragm for a rectangular speaker applied to general audio equipment.
従来の技術 従来この種の角形振動板は、第４図、第５図ａ。Conventional technology Conventional square diaphragms of this type are shown in Figs. 4 and 5a.
ｂのような構造になっていた。すなわち、コーン面６は
Ｑ−Ｂ断面部コーンのアールの大きさと、０−Ｃ断面部
コーンのアールの大きさが異なっ友角形コーン面に環状
エツジを貼り合せた角形コーンの振動板であっ几。It had a structure like b. That is, the cone surface 6 is a diaphragm of a square cone in which an annular edge is bonded to a square cone surface, and the radius of the cone at the Q-B cross section is different from that of the cone at the 0-C cross section. .
発明が解決しようとする問題点
ところが前者の振動板の構成であると、コーン面６を作
るには、コーン面のアールの大きさが０−ＢｊすＯ−Ｃ
までの４６°間で違ってくる為、金型費が高くなり、又
コーン周辺部とエツジ部の貼り合せ時の位置ぎめが困難
であり、コーン貼り合せに時間がかかり部品単価が高く
なるという問題があった。Problem to be Solved by the Invention However, in the former configuration of the diaphragm, in order to create the cone surface 6, the radius of the cone surface must be 0-BjO-C
Because the difference occurs between 46 degrees, the mold cost is high, and it is difficult to position the cone periphery and the edge when bonding, and cone bonding takes time and the unit price of the parts increases. There was a problem.
そこで本発明の振動板は、一般円錐状のコーン面周辺部
を平面角形にし、その周辺にエツジを貼り合せ時に円と
角の２ケ所の平面部で位置ぎめ出来る為、貼り合せ時間

本発明の振動板は、コーンネック部より円錐状の構造を
なし、コーン周辺部に角形の平面部を設けるとともに、
角平面部コーナにコルゲーションを設けて補強した角形
コーン面にエツジを接着するものである。Therefore, in the diaphragm of the present invention, the periphery of the cone surface of the general cone is made into a flat square shape, and when the edge is bonded to the periphery, the edges can be positioned at two flat areas, the circle and the corner, thereby shortening the bonding time. In order to solve the problem of safety, the diaphragm of the present invention has a conical structure from the cone neck part, a rectangular flat part is provided around the cone part, and
The edges are bonded to the surface of a square cone reinforced by providing corrugations at the corners of the square flat section.

角形コーン面にエツジ３を貼り合せてなるものである。EXAMPLE A speaker diaphragm according to an example of the present invention will be described below. As shown in FIGS. 1, 2, and 3, a square plane part 2 is provided on the periphery of a conical cone surface 1, and a corrugation 4 is used as a reinforcing lip on the corner plane part. It is made by pasting Edge 3 on the cone surface.
