- the present invention relates to an information terminal device such as a mobile phone, a personal digital assistant (PDA), and a game device used for various types of information communication and the like.
- an information terminal device such as a mobile phone, a personal digital assistant (PDA), and a game device used for various types of information communication and the like.
- PDA personal digital assistant
- FIG. 6 is a front view showing a conventional information terminal device.
- the information terminal device shown in FIG. 6 is, specifically, a foldable mobile phone, and shows a state from a folded state to an opened state.
- a conventional information terminal device 510 includes a main body case 550 in which an upper case 520 and a lower case 530 are connected via a connecting portion 540.
- the upper case 520 includes a substantially rectangular video display unit 560 provided on the front surface thereof, and audio output units 571 and 572 provided on the same surface as the video display unit 560.
- the audio output units 571 and 572 are speakers arranged close to two opposite corners on the diagonal line of the video display unit 560, respectively. One channel of stereo sound is reproduced from one of these speakers, and the other channel of stereo sound is reproduced from the other speaker.
- the information terminal device in the above-described conventional configuration has a problem in that it is difficult to give a sense of realism and presence due to stereophonic sound during stereophonic sound reproduction.
- the cause is that the image localization of the image display unit 560 does not match the vertical sound image localization of the audio output units 571 and 572.
- the audio output units 571 and 572 are respectively arranged close to two opposite corners on the diagonal line of the video display unit 560. That is, the sound output units 571 and 572 are arranged diagonally symmetrically with respect to the video display unit 560.
- the sound image localization of the audio output units 571 and 572 is at the center of a straight line connecting the two speakers.
- the straight line connecting the audio output units 571 and 572 is substantially parallel to the diagonal line of the upper case 520.
- the image localization of the image display unit 560 is also at the center of the rectangular screen, The video localization and the sound image localization match.
- the coincidence between the video localization and the sound image localization is limited only when the output sound pressure levels from the left and right speakers are equal. Under this limited condition, the sound image is localized exactly at the center between the left and right speakers, and coincides with the video localization of the video display unit 560.
- very few speakers are reproduced under the above conditions.
- the audio signal that changes every moment causes an output sound pressure level difference between the left and right speakers constantly. If there is a difference in output sound pressure level between the left and right speakers, the sound image will not be localized at the center of the screen, but will be localized to the left or right, whichever has the larger sound pressure level.
- the difference between the sound pressure levels of the left and right speakers allows the sound image to have depth, and the sound image localization can be moved in accordance with the movement of the image localization.
- the straight line connecting the left and right speakers is not horizontal in the conventional configuration.
- Localization in the vertical direction is a problem.
- the sound image localization also moves in the height direction by an amount that is shifted up or down from the center. This is perceived because the sense of direction for human sound acts not only in the left and right directions but also in the vertical direction.
- the image localization of the image display unit and the sound image localization of the audio output unit for the user of the information terminal device do not coincide with each other in the vertical direction.
- the sense of direction with respect to the sound image and the sense of direction with respect to the video do not match, which causes a sense of incongruity in terms of hearing.
- An information terminal device of the present invention includes a main body case, a rectangular video display section provided on the front surface of the main body case, and a predetermined arrangement angle with respect to the video display section. And a plurality of audio output units whose external shape is any one of a rectangle, an ellipse, and a track.
- the plurality of audio output units are arranged symmetrically with respect to the center line of the video display unit, and the long side or the long diameter of the outer shape of each audio output unit is set to the long side of the video display unit facing each other. Or characterized in that it is arranged close to one of the short sides It is.
- the effect of the speaker in the information terminal device of the present invention can provide good realism and realism due to stereophonic sound during stereophonic sound reproduction. That is, since the audio output unit is arranged symmetrically with respect to the center line of the video display unit, the sound image localization in the upper and lower directions of the audio output unit coincides with the vertical image localization of the video display unit. As a result, the present invention can satisfy the sense of realism and realism due to stereophonic sound during stereo sound reproduction.
