スパイダ等の振動系支持体ζ二関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a vibration system support having a V-shape with many vertical cracks so that the center part of the support can expand and contract in the circumferential direction when vibrating in accordance with the vibration of the diaphragm. A speaker with a vibrating part in its cross section has a vibration ring.
This relates to vibration system supports such as spiders.

干渉を避ける九めに、糊代２′に続く平面部２′を設け
ていた。A conventional vibrating system support with a V-shaped cross section and a longitudinal crack, for example, has 7 frames 1 and an edge suspension frame 2, as shown in Figure 1.
In order to avoid interference caused by dimensional tolerances of the diameters of the respective parts and assembly tolerances, a flat portion 2' following the glue margin 2' is provided between the two parts.

ましくない。However, if the shape of the vibration system support body can be made smaller or the tolerances are larger, it is unavoidable that the width of the flat part 2' becomes relatively or absolutely wide. It is good that the width of 2' is relatively narrow.Since it is a mere flat surface, it is easy to use a hook in the axial direction of the vibration system support, and the width is wide, whether relatively or absolutely. This is not desirable because it will increase the edge resonance frequency, increase the resonance of the spider, and lower the edge resonance frequency.

部分の自由振動を防止出来るようにしたものである。This invention provides that a cross section of a vibration system support for a speaker taken along a plane passing through six axes is in an upright or inverted V-shape with respect to the direction of the axis, and the V-shape extends in the radial direction. The locus created when vibrating back and forth with a constant amplitude and a constant speed, circles around the central axis in the circumferential direction at a constant speed, and returns to the starting point, and the innermost part of that trajectory. Between the outermost periphery of the folds of the edge suspension and the glue margin in a vibration system support whose vibration surface is the plane between the polygon formed by connecting the circumference and the outermost periphery, and the polygon formed by connecting each adjacent point, and the locus. If this part is flat, by providing a raised part, the mold will flex, cause dimensional interference between the inner diameter of the frame and the outer periphery of the folds, and separate them. The entire surface of the flat part can be fixed to the frame to prevent free vibration of this part.

が設けられている。The vibration system support of the present invention will be explained below with reference to an embodiment shown in FIG. In FIG. 2, reference numeral 1 denotes seven frames in which vibration is attached, and a diaphragm 3 is attached to this frame 1 via an edge suspension 4. The diaphragm 3 is glued to the inner glue section 4'' of the edge suspension 4,
In the edge suspension 4, the outer circumferential glue portion 4' is the frame 1.
It is glued to. Between the outermost periphery of the folds of the edge suspension seal 4 and the outer circumferential adhesive portion 4', there is a truncated conical raised portion 4''.
is provided.

ので、この部分の自由振動を防止することができる。According to the support of the vibration system having such a structure, by providing the truncated conical raised part 4', it is much more flexible (than when this part is flat), and has an inner diameter of 7 frames. Since dimensional interference with the outer periphery of the folds is less likely to occur, and since the flat portion of the external glue portion 4' can be fixed entirely to the frame 1, free vibration of this portion can be prevented.

よいが、その時は、軌跡は弧を描く、この振動系支持体
を作る場合は、各襞の面は平面である方が容易である。When creating a trajectory with When making a fold, it is easier if the surface of each fold is flat.
襞の面を平面にするには、そうなるように、半径方向の
速度および円・周方向の速度の一方或いは両方を変えて
やる必要がある。速度をはｙ一定としたのは、そのため
の配慮であって、不規則な速度という意味ではない。In order to make the surface of the folds flat, it is necessary to change the radial velocity and/or the circular/circumferential velocity to make it so. The reason why the speed is constant is to take this into account, and does not mean that the speed is irregular.
円錐台状の立上げ部には、補強のための縦裂（図示しな

上記した例では、振動系支持体は、スピーカの前方から
見て凹の形状であったが、これを第３図のように凸にし
てもよい。In the above example, the vibration system support body had a concave shape when viewed from the front of the speaker, but it may also have a convex shape as shown in FIG. 3.
以上に述べた立上げ部は、比較的撓み難い特徴はめるが
、当然、多少な）とも撓むものであるので、その高さは
、必要最小限に止めるのがよい。Although the above-mentioned raised portion has a feature that it is relatively hard to bend, it is naturally capable of bending to some extent, so its height should be kept to the minimum necessary.

〈止め′るのがよい。Similarly, when the rising portion is shaped like a truncated cone or a truncated pyramid, the inclination of the generatrix with respect to the axial direction is preferably kept as small as possible.

The purpose in this case is also to avoid dimensional interference between components and to prevent resonance.

い九が、その必要がなくなる等の効果がある。As described above, according to the present invention, since the raised portion is provided between the outermost periphery of the pleats of the vibration system support with a V-shaped cross section and longitudinal cracks and the glue allowance flat part, the vibration system support In order to avoid dimensional interference with the frame, the dimensional tolerances can be made relatively loose, and if the outside of the outermost periphery of the fold is a flat surface, edge resonance may occur due to this part. In order to prevent this, the flat parts are painstakingly and precisely coated with thick resin or the like so that they do not touch the vibrating parts, but this has the effect of eliminating the need for this.
