Abstract

PROBLEM TO BE SOLVED: To obtain the speaker with a high conversion efficiency and with excellent input-resistance by selecting a size of an outer circumferential end face of a diaphragm adhered to a voice coil bobbin to be at least a half of an entire outer circumferential end face of the diaphragm or over.
SOLUTION: A driving force exerting to a voice coil 7 acts on a diaphragm 1 via a bobbin 6 by selecting a size of an outer circumferential end face 5 of a diaphragm 1 formed thin and long adhered to the voice coil bobbin 6 to be at least a half of an entire outer circumferential end face of the diaphragm or over. A damper adhering rib 10 provided in the vicinity of both ends of the diaphragm 1 in the lengthwise direction and a damper 11 connecting to a lower side of the rib 10 and whose both ends are adhered to a frame 3 prevent rolling of the diaphragm 1 in the minor axis direction when the diaphragm 1 is vibrated vertically. Even when the diaphragm outer circumferential end 5 adhered to the voice coil bobbin 8 is not more than a 1/2 of the entire outer circumferential face, the prevention above is effective. The similar effect to design the aperture of the voice coil higher.

【0001】 [0001]

【発明の属する技術分野】本発明は映像・音響機器等に使用される細長形状のスピーカに関するものである。 BACKGROUND OF THE INVENTION The present invention relates to a speaker of elongate shape for use in video and audio equipment and the like.

【0002】 [0002]

【従来の技術】従来の細長形状のスピーカについて、図7〜図9により説明する。 BACKGROUND OF THE INVENTION for the speaker of a conventional elongated, is described by Figures 7-9. 図7は平面図であり、図8は図7をA−A断面して示した短径方向の断面図である。 Figure 7 is a plan view, FIG. 8 is a sectional view of a minor axis direction shown Figure 7 and A-A cross section.
同図において、14はスリム形状に構成されたコーン形振動板、15はエッジ、16はフレーム、17はコーン形振動板14の中央部に接合されたダストキャップ、1 In the figure, cone diaphragm configured in a slim shape 14, 15 edges, 16 frame, 17 dust cap joined to the central portion of the cone-shaped diaphragm 14, 1
9はフレーム16の内部に納まる外形寸法で構成されたダンパーである。 9 is a damper which is composed of external dimensions to fit inside the frame 16. また、20はリング状に構成されたボイスコイル、21はマグネット、22は前記リング状に構成されたボイスコイル20が収納されるリング状の磁気ギャップ、23,24は磁気ギャップ22を構成するためのヨークである。 Further, 20 voice coil, which is arranged in a ring, 21 a magnet, the magnetic gap is ring-shaped voice coil 20 that is configured to the ring is received 22, 23 and 24 for constituting a magnetic gap 22 which is the yoke.

【0003】以上のように構成された従来の細長構造のスピーカの動作について説明すると、リング状に構成されたボイスコイル20に駆動電流が流れることによってボイスコイル20がピストン運動し、振動板14がその方向に振動する。 [0003] To describe the operation of the speaker of a conventional elongated structure configured as described above, the voice coil 20 is piston movement by the drive current flows through the voice coil 20 that is configured in a ring shape, the vibration plate 14 oscillate in that direction.

【0004】その結果、振動板14より音波が放射される。 [0004] As a result, sound waves radiated from the diaphragm 14. 図9はこのスピーカの音圧周波数特性を示している。 Figure 9 shows the sound pressure frequency characteristic of the speaker.

【0005】 [0005]

【発明が解決しようとする課題】しかしながら、上記のような従来のスピーカには次のような問題点があった。 [SUMMARY OF THE INVENTION However, the conventional loudspeaker mentioned above has the following problems.
即ち、スリム形状に構成されたコーン形振動板14の中央部を点駆動するという駆動方法となるため、長軸方向の分割共振が発生し易い。 That is, since a driving method of a point drive the central portion of the cone-shaped diaphragm 14 which is configured in a slim shape, easily split resonance in the long axis direction is generated.

【0006】その結果、中高域では再生音圧の周波数特性上にピークやディップを生じ、音質の劣化を招いていた。 [0006] As a result, in the mid-high range cause the peaks and dips in the frequency characteristic of the reproduced sound pressure, it had led to the degradation of sound quality. 例えば、図9に示す音圧周波数特性上では、2kH For example, on the sound pressure frequency characteristics shown in FIG. 9, 2KH
z、3kHz及び5kHzに顕著なディップが見られる。 z, significant dip is seen in the 3kHz and 5kHz.

【0007】また、磁気ギャップ22を構成するためのヨーク23,24とボイスコイル20を含む駆動系の幅は、スピーカの短径の長さより小さくなる。 [0007] The width of the drive system including the yoke 23, 24 and the voice coil 20 to constitute a magnetic gap 22 is smaller than the length of the minor axis of the speaker.

【0008】従って、このようなスピーカでは、ボイスコイル20の口径を大きく取ることは物理的に不可能であるから、ボイスコイル20の線長も長くすることはできない。 Accordingly, in such a speaker, since taking large diameter of the voice coil 20 it is physically impossible, it is impossible to longer line length of the voice coil 20. またマグネット21の体積も小さく限定されるために、磁気ギャップ22の磁束密度を十分に確保することができない。 In order to also be restricted small volume of the magnet 21, it is impossible to sufficiently secure the magnetic flux density of the magnetic gap 22.

【0009】その結果、駆動系の力係数(B×L)は小さくなり、変換効率を高くすることが困難であった。 [0009] As a result, force factor of a drive system (B × L) is small, it is difficult to increase the conversion efficiency. さらに、ダンパー19はフレーム16の内部に納まるように曲率半径・幅ともに小さくする必要がある。 Further, the damper 19, it is necessary to reduce both the curvature radius, width to fit inside the frame 16.

【0010】そして振動系のスティフネスが大きくなって、最低共振周波数f 0が上昇し、低音域の再生が困難になるという欠点があった。 [0010] and the vibration system stiffness is increased, the rise is the lowest resonance frequency f 0, there is a drawback that the low frequency range of reproduction becomes difficult.

【0011】また、ボイスコイル20の口径を大きく取ることが不可能であることから、スピーカの耐入力を低く設定せざるを得ないという欠点を有していた。 Further, since it is impossible to increase the diameter of the voice coil 20, it had the disadvantage of inevitably set low withstand input speaker.

【0012】本発明は以上のような課題を解決することを目的とするものである。 [0012] The present invention aims to solve the above problems.
