【考案の詳細な説明】
本考案は、発泡材を用いその発泡率を部分的に
変化させたスピーカ用のエツジに関する。[Detailed Description of the Invention] The present invention relates to an edge for a speaker that uses a foam material and partially changes its foaming rate.
エツジには、波形、ロール状のものなど種々の
種類のものがあるが、発泡材を用いたエツジは、
その大半はロール状のものとして構成してある。
しかし、このロール状のエツジでは、それが共鳴
体として作用するために、音響的に悪影響が現わ
れるという欠点がある。 There are various types of edges such as corrugated and roll-shaped edges, but edges made of foam material are
Most of them are constructed in roll form.
However, this rolled edge has the disadvantage that it acts as a resonator, resulting in an adverse acoustic effect.
ここに本考案は、動作時の共鳴を無くし、音響
的に安定なスピーカ用エツジを提供する点にあ
る。 The object of the present invention is to provide an acoustically stable speaker edge that eliminates resonance during operation.
以下、本考案を図に示す一実施例にもとずいて
具体的に説明する。 Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

る。 A speaker edge according to an embodiment of the present invention is constructed of a foamed material 1, as shown in FIG. The foamed material 1 is flat at a joint surface 2 that contacts the front surface of the diaphragm, and has a spherical bulge formed at its back surface to form a bulge 3. Further, the foaming rate of the foamed portions 4 on the front and center sides is high, and the foaming rate of the foamed portion 5 on the back side is set low. Here, the highly foamed part 4
is effective in reducing the weight of the material and also prevents the formation of a hollow in the center. In addition, the foamed portion 5 on the back surface with low foaming has relatively rigidity and is effective in maintaining the shape of the bulged portion 3.
そしてスピーカ用エツジの一端は、振動板６に

いは三角形の他多角形の形状に膨出させてもよ
い。したがつて膨出部３の形状は、平面的でなく
部分的に膨出していればよく、しかもその形状
は、任意である。 One end of the speaker edge is fixed to the diaphragm 6, and the other end is held between the frame 7 and the gasket 8. Since this speaker edge does not have a recessed portion, unnecessary resonance phenomenon does not occur during operation. Furthermore, this speaker edge operates as smoothly as a conventional roll edge, and operates without resonance, so it does not adversely affect reproduced sound and exhibits good acoustic characteristics. Although the bulging portion 3 is formed in the shape of a hemisphere in the one shown in FIG. You can. Therefore, the shape of the bulging portion 3 may be any shape as long as it is not planar but partially bulging.
上記のように本考案によれば、スピーカ用エツ
ジが発泡体により構成されているため、軽量化が
達成でき、また高い発泡部分が膨出部分に凹部を
形成しないため、振動時において共鳴のない軽い
エツジが得られ、さらに膨出部分が低発泡化され

ツジと同等の機能が得られる。 As described above, according to the present invention, since the speaker edge is made of foam, weight reduction can be achieved, and since the high foamed part does not form a recess in the bulging part, there is no resonance during vibration. A light edge is obtained, and since the bulging portion is made low in foam, it exhibits sufficient rigidity and provides the same functionality as a conventional roll edge.
