関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a composite speaker for use in vehicles and the like.
従来例の構成とその問題点

た。Conventional structure and problems thereof A conventional tweeter support of this type is structured as shown in FIG. 1 or 2. That is, in FIG. 1, a tweeter 4 is fixed by a rivet 3 to a bridge 2 attached to a gasket 1 at the outer edge of the woofer.
In addition, in FIG. 2, the tweeter 4 is attached by screws 6 to a baffle plate 5 in which the woofer gasket and bridge are integrally constructed of resin.

点があつた。さらに両構造とも、ブリツジの内側
にツイータ４を取付けた場合、ブリツジの厚み分
の前室効果により、出力音圧周波数特性が乱れる
という問題があつた。 In the case of FIG. 1, the tweeter 4 is fixed using at least two rivets 3, which increases the number of parts and therefore the number of man-hours. Similarly, the structure shown in FIG. 2 also has the disadvantage of requiring a large number of parts and man-hours. Furthermore, in both structures, when the tweeter 4 is mounted inside the bridge, there is a problem that the output sound pressure frequency characteristics are disturbed due to the front chamber effect corresponding to the thickness of the bridge.
発明の目的
本発明は、このような従来の欠点を除去するも
ので、ツイータを取付けるネジ、リベツト等の部
品を省き、また工数を削減することによりコスト
ダウンをはかるとともに、より良い出力音圧周波
数特性が得られる複合型スピーカを提供するもの
である。Purpose of the Invention The present invention eliminates these conventional drawbacks, and eliminates parts such as screws and rivets for attaching the tweeter, and reduces costs by reducing man-hours, and improves the output sound pressure frequency. The present invention provides a composite type speaker that provides characteristics.
発明の構成
この目的を達成するために、本発明はツイータ
のフレーム外周部に、界磁部側に向つて切起し部

る。Structure of the Invention In order to achieve this object, the present invention provides a plurality of cut-and-raised parts on the outer periphery of the frame of the tweeter toward the field part side, and fits the tweeter into a bridge provided on the woofer from the front. In addition, the tweeter is supported on the bridge of the woofer by bending the cut and raised portion and fitting it into the bridge.
この構成によつて、ツイータのフレームそのも
のが、取付けのための部品となり、部品点数が減
る。また工法的にも、め部全部を同時めがで
き、工数削減となる。 With this configuration, the tweeter frame itself becomes a part for attachment, reducing the number of parts. Also, in terms of construction method, all the joints can be drilled at the same time, which reduces the number of man-hours.
実施例の説明
以下、本発明の一実施例における複合型スピー
カについて第３図を用いて説明する。DESCRIPTION OF EMBODIMENTS A composite speaker according to an embodiment of the present invention will be described below with reference to FIG.

ツイータ７をブリツジ９ａに固定することができ
る。 In the figure, two cut-and-raised portions 8 are provided on the outer periphery of the frame of the tweeter 7, extending toward the field portion. Further, on the outer peripheral surface of a ring-shaped bridge 9a provided on the buff-full plate 9 of the woofer to which this is attached, a protrusion 10 is provided which serves as a guide for determining the position of this cut-and-raised portion 8. The tweeter 7 can be fixed to the bridge 9a by inserting the tweeter 7 into the bridge 9a and bending the cut and raised portion 8 as shown in FIG.
発明の効果
このように、ツイータのフレームをめ部品と
共用することにより、ネジ、リベツト等の取付部
品を省くことができ、また同時めが容易に行え
るため、工数削減となり、大幅なコストダウンを
行うことができる。Effects of the Invention As described above, by sharing the tweeter frame with the fitting parts, mounting parts such as screws and rivets can be omitted, and simultaneous mounting can be easily performed, reducing man-hours and significantly reducing costs. It can be carried out.
さらに、ツイータをバツフル板前面より取り付

室効果による出力音周波数特性の乱れを防ぐこと
ができる。 Furthermore, since the tweeter can be attached from the front of the bridge plate, disturbances in the output sound frequency characteristics due to the front chamber effect due to the thickness of the bridge can be prevented.
