【発明の属する技術分野】この発明は、音質を改善した
イヤホンに関する。

【従来の技術】イヤホンは、基本的には図６に示すよう

【０００４】また、素子１の背面は、プラスチック材に

気室４１が形成されるとともに、この気室４１が透孔４
２を通じて外部に開放され、素子１の背面に所定の制動
抵抗を有する音響回路が構成される。
【０００５】さらに、素子１には、カバー４を通じてイ
ヤホンコード５が接続される。
【０００６】したがって、イヤーピース３を耳孔へ挿入
すれば、素子１の発した音は、イヤーピース３を通じて
外耳道へと導かれ、これを聴くことができる。
【０００７】
【発明が解決しようとする課題】ところが、上述のイヤ

しまう。
【０００８】これは、音響等価回路によると、次のよう
に説明される。すなわち、上述のイヤホンにおいては、
イヤーピース３により素子１の前面に気室３２が形成さ
れるとともに、この気室３２はほぼ閉じている。このた
め、図５に音響等価回路を示すように、気室３２が音響
負荷として作用するとともに、この気室３２は容量性
（容量ＣL）を示す。したがって、低音域では、制動側
が容量制御になるので、ほぼ平坦な周波数特性になる。
しかし、高音域では慣性制御になるので、レベル不足に
なる。つまり、図２に曲線Ｘで示すような周波数特性と
なる。
【０００９】そこで、図７に示すように、イヤーピース
３に小孔３３を設け、低音域のレベルを下げることが考
えられる。
【００１０】しかし、このようにすると、図４に音響等
価回路を示すように、音響負荷は、気室３２による容量
ＣLと、小孔３３によるイナータンスＭLとの並列回路に
なる。したがって、低音域では、慣性負荷になるので、
図２に曲線Ｙにより周波数特性の測定結果を示すよう
に、低音域のレベルの減衰が急峻になり、低音の伸びが
なくなる。また、容量ＣLおよびイナータンスＭLにより
中音域に共振を生じるようになる。この結果、くせのあ

【００１１】この発明は、以上のような問題点を解決し

ヤーピースにより上記電気音響変換素子の放音側に形成

に設けるとともに、この開口に通気抵抗体を設けるよう
にしたイヤホンとするものである。
【００１３】この結果、低音域の過剰さが抑えられると
ともに、中音域の共振も解消され、素直な周波数特性と

【００１４】
【発明の実施の形態】図１において、イヤホンが、電気

よりも外側の部分に形成される。また、開口３４（およ

【００１６】このような構成によれば、気室３２は、開
口３４および不織布３５を通じて外部に開放されるとと

布３５による抵抗ＲLとの並列回路になる。したがっ
て、低音域および中音域ではレベルが減衰するととも
に、低音域に向かってなだらかに減衰する。また、開口
３４により中音域における共振が解消される。
【００１７】図２において、曲線Ａは、図１のイヤホン

しかも、より低い周波数まで特性が伸びている。また、
中音域に共振がなく、特性が平坦である。
