本考案はスピーカ用振動板等に用いられる音響
機器用貼合せコーンに関する。[Detailed Description of the Invention] The present invention relates to a laminated cone for audio equipment used as a diaphragm for speakers and the like.
此種貼合せコーンは一般にコーン紙（パルプ）

円錐状となし、シート内周部をプレス成形してネ
ツク立上部を形成した構成を有する。このよう
に、従来の貼合せコーンの素材はパルプを原料と
するため、シートに繊維の方向性があり、吸湿に
よるシートの伸び率が繊維の方向と繊維に直交す
る方向とでは異なる結果、第１図の点線Ｒに示す
ように吸湿によるコーン外周部の変形が生ずる。
また、繊維と平行な方向と直交する方向とでは、
ヤング率が異なるため、コーンの円周方向で曲げ
剛性が一様にならない。このため円周方向での分
割振動（いわゆるつりがね振動）が特定のモード
で生じやすい等の欠点がある。 This kind of laminated cone is generally made of cone paper (pulp)
It has a structure in which the ends of a sheet cut into a substantially fan shape are pasted together to form a conical shape, and the inner circumference of the sheet is press-molded to form a raised neck part. In this way, since the material of conventional laminated cones is made from pulp, the sheet has fiber orientation, and the elongation rate of the sheet due to moisture absorption is different between the fiber direction and the direction perpendicular to the fibers. As shown by the dotted line R in FIG. 1, the outer periphery of the cone is deformed due to moisture absorption.
In addition, in the direction parallel to the fibers and the direction perpendicular to the fibers,
Since the Young's modulus is different, the bending rigidity is not uniform in the circumferential direction of the cone. For this reason, there are drawbacks such as split vibration in the circumferential direction (so-called suspension vibration) that tends to occur in a specific mode.
本考案はこのような欠点を解消するためになさ
れたものである。 The present invention has been made in order to eliminate such drawbacks.
以下、本考案の一実施例を示す図面につき説明
すると、第３図および第４図において、Ａは貼合
せコーンであり、該コーンＡはコーン紙を型抜き
したシート１の両端の貼り代２，２′を貼合せて
円錐状となし、シート内周部（点線Ｐ）のプレス
成形によりネツク立上部３を形成した構成であ
る。 The drawings showing one embodiment of the present invention will be explained below. In FIGS. 3 and 4, A is a laminated cone, and the cone A is a pasting allowance 2 at both ends of a sheet 1 cut out from cone paper. , 2' are pasted together to form a conical shape, and the raised neck portion 3 is formed by press molding the inner peripheral portion of the sheet (dotted line P).
以上は従来と同様であるが、本考案にあつて
は、コーン外周部即ちシート１の外周部（点線
Ｑ）を逆Ｖ字状ないし逆Ｕ字状に折り返し、全周
にわたつて連つている折り曲げ部４を形成する。 The above is the same as the conventional one, but in the present invention, the outer periphery of the cone, that is, the outer periphery of the sheet 1 (dotted line Q) is folded back in an inverted V-shape or an inverted U-shape, and continues all around the circumference. A bent portion 4 is formed.
この折り曲げ部４によつて、コーン外周部にお
ける軸方向及び軸と直交方向の強度が増し、コー
ンの吸湿による変形が抑制されると共に分割振動
に対する強度が増大すると共に、コーン外周部を
スピーカ等のエツジと接合する場合の取付作業が
容易になる。 This bent portion 4 increases the strength of the outer circumference of the cone in the axial direction and in the direction orthogonal to the axis, suppresses deformation of the cone due to moisture absorption, and increases the strength against split vibration. Installation work when joining with edges becomes easier.
本考案は上記したようにコーン外周部を折り曲
げて全周にわたつて連なつている折り曲げ部をコ
ーン外周部に設けるという簡素な構成であるが、
これによつて、コーン外周部の変形や分割振動の
発生等の欠点を解消することができる。 As described above, the present invention has a simple structure in which the outer periphery of the cone is bent and a continuous bent part is provided on the outer periphery of the cone.
This makes it possible to eliminate defects such as deformation of the outer circumferential portion of the cone and occurrence of split vibration.
