Description
【考案の詳細な説明】 本考案は、スピーカにおけるダンパの改良に関する。[Detailed explanation of the idea] The present invention relates to an improvement of a damper in a speaker.
スピーカのダンパ、特にボイスコイルボビンのピストン
運動を正常に行なうために、そのボイスコイルボビンと
フレームとの間に取り付けられるダンパは、半径方向に
コルゲーションが形成され、これによってボイスコイル
ボビンのピストン運動を吸収すると共に、そのボイスコ
イルボビンの軸心ずれを防止しているが、ボイスコイル
ボビンへの取付けは接着剤を利用した衝合接合であり、
このため接着剤の塗布量にバラツキが生じ、またスピー
カが高入力となってボイスコイルボビンが大きな振動を
起す場合には、その取付ネック部が剥離する場合がある
。The speaker damper, especially the damper installed between the voice coil bobbin and the frame, has corrugations formed in the radial direction to absorb the piston movement of the voice coil bobbin and to ensure normal piston movement of the voice coil bobbin. , which prevents the voice coil bobbin from misaligning, but it is attached to the voice coil bobbin by a butt joint using adhesive.
This causes variations in the amount of adhesive applied, and when the voice coil bobbin generates large vibrations due to high input from the speaker, the mounting neck may peel off.
本考案は斯る点に鑑みたもので、ダンパのボイスコイル
ボビンへの取付部の形状に改良を加えて、前記したよう
な問題点を解消せんとするものである。The present invention has been developed in view of these points, and attempts to solve the above-mentioned problems by improving the shape of the attachment portion of the damper to the voice coil bobbin.
以下、図を参照して本考案の一実施例を説明すると、図
（こおいて１はボイスＴ’フィルボビン、２はフレーム
で、その両者間にダンパ３が接続されるが、そのダンパ
３のボイスコイルボビン１への取付部には、ボイスコイ
ルボビン１の周面に略平行に接する周舌片３ａ、その周
舌片３ａから段部３ｂを介して第１コルゲーシヨン３ｄ
の山を形成すべく立上る立上り部３Ｃが形成され、また
第１コルゲーシヨン３ｄの山谷は他のコルゲーションの
山谷よりも大きくなっている。Hereinafter, an embodiment of the present invention will be described with reference to the drawings. At the attachment part to the voice coil bobbin 1, there is a circumferential tongue piece 3a that is in contact with the circumferential surface of the voice coil bobbin 1 in a substantially parallel manner, and a first corrugation 3d that extends from the circumferential tongue piece 3a via a step portion 3b.
A rising portion 3C is formed that rises to form a peak, and the peaks and valleys of the first corrugation 3d are larger than those of the other corrugations.
そして、前記した段部３ｂと立上り部３Ｃ及びボイスコ
イルボビン１の外周面とで形成される空間には、接着剤
４の注入と共に、振動板５の基端部が埋め込まれている
。Then, in the space formed by the step portion 3b, the rising portion 3C, and the outer peripheral surface of the voice coil bobbin 1, the adhesive 4 is injected and the base end portion of the diaphragm 5 is embedded.
なお接着剤４は、ダンパ３の周舌片３ａとボイスコイル
ボビン１の外周面との間にも注入されている。Note that the adhesive 4 is also injected between the circumferential tongue piece 3a of the damper 3 and the outer peripheral surface of the voice coil bobbin 1.
このような構造とすれば、ボイスコイルボビン１の外周
面、ダンパ３の段部３ｂ、及び立上り部３Ｃで形成され
る空間が製品間にバラツキなく一定となるので、そこに
注入すべき接着剤４の量も一定になり、接着強度にバラ
ツキがなくなる。With such a structure, the space formed by the outer circumferential surface of the voice coil bobbin 1, the stepped portion 3b of the damper 3, and the rising portion 3C will be constant without variation between products, so that the adhesive 4 to be injected therein will be constant. The amount becomes constant, and there is no variation in adhesive strength.
またその接着剤４は同時に振動板５をも固定するように
なり、そこにおける接着強度は大きくなる。Furthermore, the adhesive 4 also fixes the diaphragm 5 at the same time, increasing the adhesive strength there.
ボイスコイルに音声信号電流が流れることによって、ボ
イスコイルボビン１が上下方向にピストン運動し、特に
上方向に大振幅振動した場合、ダンパ３のボイスコイル
ボビン１への取付部分において矢印方向に接着剤４から
の剥離力が生ずるが、第１コルゲーシヨン４ｄの谷が大
きくなっているので、上下振動は主にその谷の部分で吸
収されるようになり、その剥離力は小さなものに止どま
って、支障を起す程度に至ることはない。When an audio signal current flows through the voice coil, the voice coil bobbin 1 makes a piston movement in the vertical direction, and especially when it vibrates with a large amplitude in the upward direction, the adhesive 4 is released from the adhesive 4 in the direction of the arrow at the attachment part of the damper 3 to the voice coil bobbin 1. A peeling force of It never reaches the level where it causes.
なお、周舌片３ａ、段部３ｂは必らずしも必要はなく、
ボイスコイルボビンと立上部３Ｃとの間に振動板５を固
着する構造であっても良い。Note that the circumferential tongue piece 3a and the stepped portion 3b are not necessarily necessary.
The structure may be such that the diaphragm 5 is fixed between the voice coil bobbin and the rising portion 3C.
以上から本考案によれば、接着剤の塗布量にバラツキが
無くなり、また接着強度も大きくなり、大入力によって
接合部が剥離するというようなことも生じなくなる。As described above, according to the present invention, there is no variation in the amount of adhesive applied, the adhesive strength is increased, and there is no possibility that the bonded portion will peel off due to a large input.
