Abstract
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.
