[Patent Document 2] Japanese Unexamined Patent Publication No. 2002-359890

[Patent Document 3] Japanese Utility Model Registration No. 3044340

However, although the technique proposed in the said patent documents 1-3 can aim at the improvement of a stereo effect, the improvement of the sound quality of the generated voice itself is not aimed at.

In view of the above circumstances, an object of the present invention is to provide a portable terminal having both portability and improvement in sound quality.

A portable terminal of the present invention which achieves the above object is a portable terminal which executes a process including a voice output process,

A speaker to give a voice,

A portion having a speaker box capable of moving to at least two positions or postures and acting as a resonance box of the speaker,

The speaker box is characterized in that the volume changes as the portion moves.

Since the portable terminal of the present invention is provided with a speaker box to which a portion moves and changes its volume by the movement thereof, it is possible to output high-quality sound by emitting sound in a state where the volume of the speaker box is expanded. .

Herein, the portable terminal of the present invention specifically moves, for example, between a storage space forming unit in which the speaker box forms a storage space inside the portable terminal, a storage position stored in the storage space, and a protruding position protruding from the portable terminal. It is possible to include a moving box having an inner space and an opening formed therein for communicating the inner space and the storage space when moved to the protruding position.

In this case, the moving box may be projected in the transverse direction with respect to the forward direction for sounding outward, or the moving box may be projected in the forward direction for sounding outward.

Here, in the case where the moving box protrudes in the horizontal direction, two moving boxes may be provided, and each moving box may be separated from the left and right to protrude.

The moving box may be moved between the storage position and the protruding position by the slide, or the moving box may be moved between the storing position and the protruding position by rotation.

If the above-mentioned moving box is provided, a space which is enlarged to both the storage space in which the moving box is stored and the internal space of the moving box is formed when the moving box is moved to the protruding position. Therefore, when voice is made while the moving box is moved to the protruding position, a large space is used as the resonance box, resulting in high quality voice.

Further, in the portable terminal of the present invention, it is preferable that the moving box has a first soundproof part for sounding outward and the storage space forming part also has a second soundproof part for sounding outward. .

With this arrangement, the moving box can be moved to the protruding position to obtain high quality sound, and the sound quality can be made even though the moving box is placed in the storage position.

As described above, according to the present invention, both portability and sound quality improvement can be achieved.
