本考案はエツジ塗料のみをエツジとして使用しているス
ピーカに係り、振動板に改良を加えることによって特性
の向上や品質の安定化を計ろうとするものである。[Detailed description of the invention] The present invention relates to a speaker that uses only edge paint as an edge, and attempts to improve the characteristics and stabilize the quality by improving the diaphragm.
従来のこの種のスピーカは第１図に示すように構成され
ていた。A conventional speaker of this type was constructed as shown in FIG.
すなわち、フレーム１の周縁部に内側上部に段部２をも

ツジ塗料受台３の段部２間にエツジ塗料７を塗布して構
成されていた。That is, an edge paint holder 3 having a step 2 on the inner upper part is attached to the peripheral edge of the frame 1, and this edge paint holder 3
The peripheral edge of the diaphragm 4 is placed close to the diaphragm 4, and an edge paint 7 is placed between the edge paint receiving part 6 having a bent structure on the outer periphery of the flat part 5 of the peripheral edge of the diaphragm 4 and the stepped part 2 of the edge paint holder 3. It was made up of a coating of
このエツジ塗料７としてはビスコロイド、アクノル・ウ
レタン系樹脂などが用いられている。As this edge paint 7, viscolloid, Acnol urethane resin, etc. are used.
上記構成で振動板４の平坦部５はエツジ塗料７が振動板
４の内側へ流れこむのを防ぐために設けられたものであ
るが、この平担部がエツジとしての若干の働きをもち、
エツジとしてのエツジ塗料７の有効性を最大限利用でき
ないものであった。In the above structure, the flat part 5 of the diaphragm 4 is provided to prevent the edge paint 7 from flowing into the inside of the diaphragm 4, but this flat part has a slight function as an edge,
The effectiveness of Edge Paint 7 as an edge could not be utilized to its fullest extent.
本考案は以上のような従来の欠点を除去するものである
。The present invention eliminates the above-mentioned drawbacks of the prior art.
以下、本考案の実施例を図面第２図、第３図により説明
する。Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.
８は磁気回路で、この磁気回路８はセンターポール９を
有するプレート１０、リング状のマグネット１１．同じ
くリング状の上部プレート１２によって構成されている
。8 is a magnetic circuit, and this magnetic circuit 8 includes a plate 10 having a center pole 9, a ring-shaped magnet 11. It is also constituted by a ring-shaped upper plate 12.
この磁気回路８にはフレーム１３が結合され、このフレ
ーム１３の周縁部にはリング状で、その内側上部に段部
１４を設けたエツジ塗料受台１５が固着されている。A frame 13 is connected to the magnetic circuit 8, and a ring-shaped edge paint holder 15 is fixed to the peripheral edge of the frame 13, and has a stepped portion 14 at its upper inner side.
このエツジ塗料受台１５の内側にはコーン状の振動板１
６が配置され、この振動板１６の周縁部には半円状のふ
くらみ部１７が形成され、このふくらみ部１７はエツジ
塗料受台１５の段部１４と平行面より角度θだけ上向き
のＲをもつように構成されており、上記段部１４とふく
らみ部１７の外周面間にビスコロイド、アクリル・ウレ
タン系樹脂などからなるエツジ塗料１８が塗布されてい
る。Inside this edge paint holder 15 is a cone-shaped diaphragm 1.
6 is arranged, and a semicircular bulge 17 is formed at the peripheral edge of this diaphragm 16, and this bulge 17 has an upward radius of an angle θ from a plane parallel to the stepped portion 14 of the edge paint holder 15. An edge paint 18 made of viscolloid, acrylic/urethane resin, etc. is applied between the outer peripheral surfaces of the stepped portion 14 and the bulged portion 17.
そして、振動板１６の中央部にはボイスコイル１９が結
合され、このボイスコイル１９は中間部をダンパー２０
で保持されて上記磁気回路８の磁気ギャップ２１に偏心
することなくはまりこんでいる。A voice coil 19 is coupled to the central portion of the diaphragm 16, and the voice coil 19 has an intermediate portion connected to a damper 20.
It is held in the magnetic gap 21 of the magnetic circuit 8 without eccentricity.
なお、振動板１６の中央部上面にはダストキャップ２３
か′貼付けられている。Note that a dust cap 23 is provided on the upper surface of the center part of the diaphragm 16.
Or' pasted.
以上のように本考案のスピーカは構成されるため、振動
板周縁部のふくらみ部でエツジ塗料の振動板内部への流
入を阻止し、振動板の周縁部の強度も向上して破損しに
くいものとなり、しかも、エツジとしてはエツジ塗料の
みが働くことになってエツジ塗料のもつ特性が最大限生
かされて音響特性の平坦化とともに歪みの低減化も計れ
、実用的価値の大なるものである。As the speaker of the present invention is constructed as described above, the bulge on the periphery of the diaphragm prevents the edge paint from flowing into the diaphragm, and the strength of the periphery of the diaphragm is improved, making it less likely to be damaged. Moreover, since only the edge paint works as an edge, the characteristics of the edge paint are utilized to the maximum, flattening the acoustic characteristics and reducing distortion, which is of great practical value.
