問題があつた。 Although the diaphragm 7 is shaped like a truncated cone with a high center and a low periphery to make it thinner, the height of the damper 9 is shortened, and the speaker performance such as minimum resonant frequency and input resistance is reduced. I had a problem that was getting worse.
本考案は以上のような従来の欠点を除去するも

合した構成としたものである。 In order to achieve the above object, the present invention installs a magnetic circuit inside a frame, attaches a truncated cone-shaped diaphragm to the periphery of the frame, the center of which is higher than the periphery, and connects an inner cylinder with a coil and a magnetic circuit. The upper part of the voice coil is made of an outer cylinder that fits into the outer periphery of the diaphragm, and the upper part of the voice coil is connected to the center of the diaphragm, and the damper is connected to the lower part of the outer cylinder.
以下、本考案の実施例を図面第２図により説明
する。 Hereinafter, an embodiment of the present invention will be explained with reference to FIG. 2 of the drawing.
１２はヨーク１３内に円板状のマグネツト１４
と上部プレート１５の積層体を組込んで構成され
る磁気回路で、この磁気回路１２はフラツトな内
底面をもち、周縁部に段付突壁２６を有するフレ
ーム１７の中央上面に結合されている。 12 is a disc-shaped magnet 14 inside the yoke 13.
This magnetic circuit 12 has a flat inner bottom surface and is connected to the central upper surface of a frame 17 having a stepped wall 26 at the peripheral edge. .
このフレーム１７の段付突壁１６の段部には周
縁部が低く中央部が高くなるように円錐台状に形
成された振動板１８の周縁部がガスマツト１９と
ともに結合されている。 The peripheral edge of a diaphragm 18, which is formed into a truncated conical shape so that the peripheral edge is low and the center is high, is coupled to the stepped portion of the stepped wall 16 of the frame 17 together with a gas mat 19.
この振動板１８の中央部には、コイル２０を有

底面に固着したダンパー２５の内周縁が結合さ
れ、ボイスコイル２４のコイル２０は上記磁気回
路１２の磁気ギヤツプ２６に偏心することなくは
まりこんでいる。 At the center of the diaphragm 18, there is a bobbin that includes an inner cylinder 21 having a coil 20, an outer cylinder 22 that fits into the outer periphery of the magnetic circuit 12, and a connecting part 23 that connects the upper part of the inner cylinder 21 and the outer cylinder 22. The upper part of the voice coil 24 is coupled to the voice coil 24. That is,
The outer cylinder 2 of the voice coil 24 is located in the center of the diaphragm 18.
The upper parts of 2 fit together and are connected. Also,
The inner peripheral edge of a damper 25 whose peripheral edge is fixed to the inner bottom surface of the frame 17 is connected to the lower part of the outer cylinder 22, and the coil 20 of the voice coil 24 is fitted into the magnetic gap 26 of the magnetic circuit 12 without eccentricity. .
また、ボイスコイル２４の連結部２３にはダス
トキヤツプ２７が貼付けられている。 Further, a dust cap 27 is attached to the connecting portion 23 of the voice coil 24.
以上のように本考案のスピーカは構成されるた
め、ダンパーを十分な高さのものとすることがで
きて、スピーカとしての最低共振周波数、耐入力
の優れたものとでき、しかも全高もわずかに磁気
回路の高さより少し高くなるだけできわめて薄形
化が計れるなどの利点をもち、実用的価値の大な
るものである。 Since the speaker of the present invention is constructed as described above, the damper can be made of sufficient height, and the minimum resonance frequency and input resistance of the speaker are excellent, and the overall height is also small. It has the advantage of being extremely thin by being slightly higher than the height of the magnetic circuit, and has great practical value.
