    • An ear speaker device includes an electroacoustic transducer including a housing mounted at a predetermined position of listener's head, a speaker unit mounted on one surface in the housing, and positioned away from an entrance of the listener's external acoustic meatus for a predetermined distance when the housing is mounted on the listener's head, and a tubular duct extended so as to allow a sound generated by the housing in the inner space thereof to reach the vicinity of the entrance of the listener's external acoustic meatus, and a hole for emitting sound of the duct is oriented to the opposite direction with respect to the entrance of the external acoustic meatus; and a mounting part used for mounting the electroacoustic transducer on the listener's head in a manner that the predetermined distance is provided between the speaker unit and the entrance of the listener's external acoustic meatus.
    • 耳式扬声器装置包括电声换能器,其包括安装在收听者头部的预定位置处的壳体,安装在壳体中的一个表面上的扬声器单元,并且当外壳的外壳处于预定距离时远离收听者的外耳道的入口定位 安装在收听者的头部上,并且管状管道延伸以允许由其内部空间中的壳体产生的声音到达收听者的外部声道的入口附近,以及用于发射管道的声音的孔 相对于外耳道的入口朝向相反方向; 以及用于将电声换能器安装在收听者头部上的安装部分,其方式是在扬声器单元和收听者的外耳道的入口之间提供预定距离。
