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.
Claims6
An electronic device, comprising:
- a flat housing that has a main face and a small thickness direction perpendicular to the main face;
- and
- a speaker that is arranged in the housing such that an opening face of a cone portion is parallel to the main face,
- wherein on a reverse side of the main face, an enclosed space is formed above the opening face of the cone portion of the speaker,
- a concave portion is formed in the main face,
- an input operation portion including an input key moveable in the thickness direction of the housing is arranged in the concave portion,
- an opening portion of the enclosed space is formed in a wall face of the concave portion, and
- the opening portion of the enclosed space is formed in a face not parallel to the main face of the housing and positioned nearer to a bottom side of the housing than a key drop of the input key.
