DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable information terminal with a telephone function, and more particularly to a speaker arrangement structure.

[0002]

2. Description of the Related Art Generally, a portable information terminal with a telephone function includes:
As shown in FIGS. 5 and 6, one antenna for transmitting and receiving radio waves of a telephone, two receivers for receiving a telephone call (speakers for listening while listening to an earpiece), and three displaying various information. A display, a numeric keypad for inputting information such as a telephone number, and a microphone for transmitting telephone calls are provided. In the case of FIG. 6, a touch panel, a digitizer, and the like are provided so as to overlap with the display, and a virtual keyboard is displayed on the display to serve as a numeric keypad.

[0003] In the case of having a hands-free function,
A speaker 6 (a speaker that listens away from the ear during a hands-free call) is also provided (in FIGS. 5 and 6, the speaker 6 is disposed on the back surface).

Conventionally, a portable information terminal with a telephone function has been configured such that a receiver, a display, a numeric keypad, and a microphone are arranged on the same surface (usually the surface) of a housing.

[0005] In the case of having a hands-free function,
A speaker was located on the back of the housing.

[0006]

However, when a telephone call is made in the above-mentioned conventional example, a fingertip hits the display surface when the housing is grasped with a hand, and a fingerprint is applied when the receiver is put on the ear. Because the minutes were on the display surface, the information displayed on the display was very difficult to see. In particular, when a touch panel or the like is arranged on the display surface to constitute a virtual numeric keypad (virtual keyboard), fingerprints and grease easily adhere to the display, making it more difficult to see, and at the same time, the touch panel surface becomes slippery. When inputting, the input operation feeling changed, making it difficult to input.

In recent years, devices have tended to be reduced in size and weight. In order to arrange a receiver, a display, a numeric keypad, and a microphone on the same surface (usually, the surface) of a housing, it is necessary to reduce the size of each component or unit. There is. When the size of the receiver is reduced, it is necessary to increase the amplification factor of the audio amplifier in order to increase the sound pressure, which requires more power. When the display is reduced in size, the display information is small and hard to see, or the amount of information that can be displayed on one screen is small and hard to see. When the numeric keypad is made smaller, key input becomes difficult.

[0008] In the case of having a hands-free function,
Since it is difficult to arrange the speaker (relatively large) on the same surface as the receiver, display, numeric keypad, microphone, etc., it is often placed on the back of the housing, increasing the amplification of the audio amplifier and outputting a large volume Therefore, there are disadvantages such as the necessity of a large amount of power of the amplifier and the necessity of making the speaker one size larger. In addition, noise was scattered behind the device.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is possible to prevent fingerprints and grease from adhering to the display surface, to eliminate the need to increase the amplification factor of an audio amplifier, and to use key input.
