    • An electronic device of the present invention has a configuration in which an enclosed space is formed continuously from an opening face of a cone portion of a speaker on a reverse side of a main face of a flat housing, and an opening portion of the enclosed space is formed in a face not parallel to the main face of the housing, whereby even when a reduction in diameter of a speaker is inevitable and there is a limit to a space volume for housing the speaker due to the downsizing of the device, sound information can be reproduced with higher quality.
    • 本发明的电子装置具有这样的结构,其中,从平坦壳体的主面的相反侧的扬声器的锥形部的开口面和封闭空间的开口部连续形成封闭空间 形成在不平行于壳体的主面的面上,由此即使扬声器的直径的减小是不可避免的,并且由于装置的小型化而使扬声器的容纳空间容积受到限制,所以声音信息 可以以更高的质量再现。
