ＨｉＦｉ 再生を可能ならしめる機能を有するもので
あり、第１図はその基本的形状を示したものである。The equalizer for rear-type speakers with slits has the function of uniformly transforming the acoustic power generated from the diaphragm provided close to the equalizer, and also performing phase equalization to enable HiFi playback. The figure shows its basic shape.
形状的に具備すべき条件はスリン）１，２．３を有し、
かつ円周方向にスリット巾が均一であること、スリット
を形成する回転体４，５，６．７の上面が同一の球面上
にあること、スリットは球面から遠ざかるに従い中心軸
に近寄ること、およびスリットの中心軸に対して垂直な
断面における面積が球面から遠去かるに従い徐々に広く
なることの４点である。The conditions that should be met in terms of shape are Surin) 1, 2.3,
and that the slit width is uniform in the circumferential direction, that the upper surfaces of the rotating bodies 4, 5, and 6.7 forming the slits are on the same spherical surface, that the slit approaches the central axis as it moves away from the spherical surface, and The four points are that the area in the cross section perpendicular to the central axis of the slit gradually increases as it moves away from the spherical surface.

上イコライザー片と呼ぶ。In addition, in order to maintain the shape of the equalizer, an engaging part is required to fix each rotating body 4, 5, 6.7 in a state where they are separated from each other. It is called.
従来、各イコライザー片を順次接着してイコライザーを
得ていたが、接着工程の自動化が難しいこと、接着剤の
乾燥もしくは硬化に長時間を要することから量産性が劣
っていた。Conventionally, equalizers were obtained by sequentially gluing each equalizer piece together, but mass production was poor because it was difficult to automate the gluing process and it took a long time for the adhesive to dry or harden.
そこで、本発明は迅速に組立て可能なリアタイプホーン
スピーカー用イコライザー及びその製造方法を提供する
ものであり以下に、その一実施例を図面を参考に説明す
る。SUMMARY OF THE INVENTION The present invention provides an equalizer for a rear type horn speaker that can be assembled quickly and a method for manufacturing the same, and one embodiment thereof will be described below with reference to the drawings.
第２図において、受は台８に置かれたイコライザー片９
の内側のイコライザー片１０をイコライザー片９の上に
載せ、然る後、イコライザーの球面と同一の半径の凹球
面１２を有するホーン１１を下降させてイコライザー片
１０と接触させ、次に加圧しながらホーン１１にて超音
波エネルギーを付与する。In FIG. 2, the receiver is an equalizer piece 9 placed on a stand 8.
Place the inner equalizer piece 10 on the equalizer piece 9, then lower the horn 11 having a concave spherical surface 12 with the same radius as the equalizer's spherical surface to contact the equalizer piece 10, and then press the Ultrasonic energy is applied using the horn 11.
イコライザー片９とイコライザー片１０との球面は、当
被はイコライザー片１０に一体形成されたエネルギーダ

接合面１４．１５は溶は始め、イコライザー片１０は下
方に移動し、やがてイコライザー片９とイコライザー片
１０の球面とが一致する。The spherical surfaces of the equalizer piece 9 and the equalizer piece 10 are such that the spherical surface of the equalizer piece 10 is located above due to the difference in height between the energy director 13 and the uneven engagement portion that are integrally formed on the equalizer piece 10. When welding starts, the energy director 13 and the joining surfaces 14 and 15 of the uneven engagement portion begin to melt, the equalizer piece 10 moves downward, and eventually the spherical surfaces of the equalizer piece 9 and the equalizer piece 10 coincide. .
なお、各イコライザー片は熱可塑性樹脂にて成形されて
いる。Note that each equalizer piece is molded from thermoplastic resin.
両球面が一致すると、ホーン１１から発生する超音波エ
ネルギーはイコライザー片９，１０の両方に分散し溶着
はそれ以上進まない。When both spherical surfaces coincide, the ultrasonic energy generated from the horn 11 is dispersed to both the equalizer pieces 9 and 10, and welding does not proceed any further.
従って溶着条件のうち溶着時間をやや長めに設定するこ
とにより、両イコライザー片の球面を正確に一致させる
ことができる。Therefore, by setting the welding time a little longer among the welding conditions, the spherical surfaces of both equalizer pieces can be made to match accurately.
この場合のイコライザー片の係合部およびエネルギーダ
イレクタ−の形状は、第３図および第４図に示すような
形状が望ましい。In this case, the shapes of the engaging portion of the equalizer piece and the energy director are preferably as shown in FIGS. 3 and 4.

凹係合部２０が設けられている。FIG. 3 is a partial cross-sectional view of an equalizer piece in an embodiment of the present invention, and shows the convex connecting portion 1 of the inner equalizer piece 16 of the two corresponding equalizer pieces 16 and 17.
An energy director 19 is provided on the bottom surface of the equalizer 8, and a concave engagement portion 20 is provided on the outer equalizer piece 17 in correspondence with the convex engagement portion 18.

の寸法を設定しである。Because the energy director 19 and both retaining parts 18.20 are melted by welding, the height of the equalizer piece 16 and the equalizer piece 17 in the central axis direction is the height of the energy director plus 0.1 to 0.2 virtt. The dimensions of both engaging portions before welding are set so that the equalizer piece 16 becomes taller.
また溶着強度を高めるため番と両係合部の接合面は中心
軸に対して直角であることが望ましい。Further, in order to increase the welding strength, it is desirable that the bonding surfaces between the number and both engaging portions be perpendicular to the central axis.

ましい。FIG. 4 shows the convex engagement portion 18 and the concave engagement portion 20 in FIG.
It is a sectional view showing a state after welding in which the energy director and the resin 21 of both engaging parts melted by welding are placed in the concave engaging part 2 so that the resin 21 does not protrude onto the spherical surface.
It is desirable that the width of 0 is slightly larger than the width of the convex retaining portion 18.
このようにして外側のイコライザー片から順次溶着して
積み重ねることにより、イコライザーを得ることができ

り、また特に順序を決めなくとも可能である。Further, if the receiver is provided with a stand 8 for each equalizer piece, it is possible to stack the equalizer pieces one after another starting from the inner equalizer piece, and it is also possible to stack the equalizer pieces one after another, without having to decide on a particular order.
また凸脈合部、凹係合部を設ける位置は実施例に制限さ

面の中部に設けても、溶着上差支えない。Further, the positions where the convex interlocking portions and the concave engaging portions are provided are not limited to the embodiments, and may be provided in the middle of the side surface of the equalizer piece if the shape is possible without any problem in terms of welding.

の接合強度が得られ作業性が向上する。As is clear from the above description, according to the speaker equalizer and the manufacturing method thereof of the present invention, the energy director formed on either the concave engagement portion or the convex engagement portion of the equalizer piece is welded to the concave and convex engagement portions. The plurality of equalizers are fixed at the joints, and the positional relationship is accurately fixed.Since the welding of the tags or the energy director is done by ultrasonic welding, the desired joint strength can be obtained immediately after the welding process. This improves work efficiency.

適する等の効果を有する。Furthermore, since both the concave and convex engaging portions are joined at a surface that is substantially perpendicular to the axis of the equalizer, even when multiple equalizers are sequentially welded, the axes do not shift and the spherical surfaces can be aligned. It has the advantage of being easy to automate and suitable for mass production.
