Description

Speakerphone mounting structure of portable wireless terminal {ENGAGING STRUCTURE FOR SPEAKER PHONE IN PORTABLE RADIOTELEPHONE}

The present invention relates to a portable wireless terminal, and more particularly, to a speaker phone mounting structure of a portable wireless terminal configured to extend the display unit and the key button unit.

In recent years, as portable wireless terminals become more and more popular, terminals of various designs have emerged. In addition, according to the user's demand trend, the terminal is becoming smaller and lighter and smaller, and its functions are becoming more diversified.

On the other hand, while the terminal becomes smaller and lighter and shorter, the display unit such as an input key button part or an LCD is increasing in size on the terminal to be convenient in using the function.

Figure 1 is a general perspective view of a portable wireless terminal according to an embodiment of the prior art, the general portable wireless terminal has a main body 110, a flip cover 130 and the flip cover 130 is installed to collect the call sound It consists of a hinge device (not shown) configured to be opened and closed by a mechanical angle.

The main body 110 includes an upper casing frame 111 and a lower casing frame 112, and an antenna device 120 is installed at one side of the uppermost end of the main body. In addition, a speaker device 113 is located on the upper side of the main body, and a display unit 114 including an LCD module is located below, and a keypad unit 115 having a plurality of key buttons is provided on the lower side thereof. . A microphone device 200 capable of transmitting a voice to the other party is installed below the keypad unit 115.

In this case, the speaker unit including the display unit and the speaker phone composed of the keypad unit and the LCD module is sequentially installed on the upper casing frame of the terminal. Thus, the keypad unit, the display unit, and the speaker unit must be installed. And when the terminal is miniaturized, the volume of the devices are reduced, which causes disadvantageous operation.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a speaker phone mounting structure of a portable wireless terminal, which is configured to realize miniaturization and light weight of the terminal.

Another object of the present invention is to provide a speaker phone mounting structure of a portable wireless terminal configured to increase the size of the display unit or the keypad unit to facilitate operation while maintaining a smooth speaker phone function.

In order to achieve the above object, the present invention provides a portable wireless terminal having a configuration in which a speakerphone, an LCD module, a keypad, and a microphone are sequentially installed and installed on a main body of an upper casing frame and a lower casing frame.

The speaker phone is installed to partially overlap with the LCD module on the lower casing frame of the main body to expand the storage space of the keypad unit and the LCD module to be accommodated.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In the case where it is determined that the gist of the present invention may be unnecessarily obscured, detailed description thereof will be omitted.

The speaker phone according to the present invention is installed on the lower casing frame of the portable wireless terminal, so that the speaker phone is partially overlapped with the LCD module installed on the upper casing frame.

Figure 2 is a side cross-sectional view of a portable wireless terminal equipped with a speaker phone according to an embodiment of the present invention, the basic function of the terminal on the main body 110 consisting of the upper casing frame 111 and the lower casing frame 112 Electronic components having electronic functions (Electronic Function Group) are housed.

On the upper casing frame 111, a display unit 114 on which the LCD module is mounted and a keypad unit 115, which is a key input means, are installed under the display unit 114. In this case, a sign language hole 22 capable of receiving a voice of the other party is formed above the display unit 114, and a conversation is provided below the keypad unit 115 so as to transmit its own voice to the other party. The hole 21 is formed. Therefore, a microphone (not shown) may be installed in the main body at a position corresponding to the talk hole 21, and a speaker phone 10 may be installed in the main body at a position corresponding to the sign language hole 22. have.

At this time, the microphone (not shown) installed at a position corresponding to the talk hole 21 is installed on the upper casing frame 111 like the LCD module or the keypad 115, but the sign language hole 22 The speaker phone 10 installed at the position corresponding to) is installed on the lower casing frame 112. That is, when the speaker phone 10 is installed on the lower casing frame 112, a part of the speaker phone 10 is installed to overlap with the display unit 113, so that the display unit 114 by the overlapping amount. You can extend the size of.

In addition, between the speaker phone 10 and the sign language hole 22 on the upper casing frame 111, a predetermined length and diameter for transmitting a voice generated in the speaker phone 10 to the sign language hole 22 may be provided. The tube 11 which has is provided. In addition, on the hydration hole 22, a sponge 12 having a dustproof function for preventing dust from entering the terminal body may be installed.

In addition, a nonwoven fabric 13 may be attached on the rear surface of the speaker phone 10 to realize the proper sign language characteristic.

3 is a perspective view of a portable wireless terminal according to an exemplary embodiment of the present invention. As compared with FIG. 1, it can be seen that the display unit 114 is extended by an overlapping portion of the speaker phone 10 and the LCD module.

On the other hand, the portion of the speaker phone 10 and the display unit 114 overlapping the present invention (L portion of Figure 2) can be applied to the expansion of the keypad portion to facilitate the user's operation, miniaturization of the terminal and light and small Can be applied.

4 is a graph showing the output characteristics of the speaker phone according to the present invention and the prior art, curve A shows the output characteristics of the speaker phone according to the present invention without a nonwoven fabric, curve B is a general The output characteristics of the speakerphone provided in the portable terminal are shown, and the curve C shows the output characteristics of the speakerphone according to the present invention with the nonwoven fabric attached thereto.

According to the present invention, a value of 2.5 mm in diameter and 7.0 mm in length was measured while maintaining a distance of 1 mm from the front of the speaker phone. It can be seen that the output curve B is almost identical.

As described above, the speaker phone mounting structure according to the embodiment of the present invention can extend the display unit or the keypad unit to the user's convenience while maintaining the size of the existing terminal, and satisfy the user's desire by miniaturizing the terminal. It can be effected.
