BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal, and more particularly, to a pop-up type speaker / microphone of a portable terminal, which constitutes at least one sub-speaker / microphone that is pulled in / out as the terminal is pressed.

In general, the term “portable terminal” refers to a device that a user can carry and wirelessly communicate with a counterpart. Such portable communication devices are classified into various types in appearance. For example, wireless terminals are classified as bar-type, flip-type, or folder-type wireless terminals according to their appearance. Bar-type wireless terminal means that the single housing is configured in the bar-type, flip-type wireless terminal means that the flip or cover is rotatably configured by the hinge device in the bar-shaped housing, folder-type wireless The terminal means that the folder is configured to be rotatably connected to the single bar-shaped housing by a hinge device and to be folded.

In addition, the portable terminal may be classified into a neck wearable type or a wrist wearable type according to a body wearing position or a wearing method. A necklace-type wireless terminal refers to a portable method of wearing a terminal around a neck using a string, and a wrist-type wireless terminal refers to a portable method of wearing a terminal to a wrist.

In addition, the wireless terminal may be classified into a rotation-type or sliding-type wireless terminal according to an opening and closing method. Rotational-type wireless terminal means that the two housings are rotatably connected to open and close facing each other, the sliding-type wireless terminal is one of the two housings, one of the housing facing the longitudinal sliding movement It means to open and close. The variously classified wireless terminals listed above will be readily understood by those of ordinary skill in the art.

Meanwhile, the above-mentioned conventional portable terminals are essentially provided with an antenna device, a data input / output device, and a data transmission / reception device. Of course, the data input device is commonly used as a keypad for inputting data mainly by a finger pressing operation, a touch pad or a touch screen is also used. In addition, the data output device commonly uses an LCD.

In general, a keypad used for data input consists of an arrangement of a plurality of keys. These keys consist of numeric keys, letter keys, send keys, end keys, function keys, and the like. In addition, the keys are usually arranged in place in the number of about 15 to 20 on the upper surface of the housing of the portable terminal. Of course, the keys are exposed from the upper surface so that the user inputs the desired data by pressing a finger. In addition, the conventional portable communication device for a video call is provided with a camera lens that is a means for shooting, through which it is possible to make a video call with the other party, or to shoot a desired subject.

However, users are increasingly in need of informatization, and in reality, it is very inconvenient when communicating using a conventional portable terminal in an internet environment or a multimedia environment. In particular, it is inconvenient when a user needs to watch a video on demand or watch TV using a conventional portable terminal. This is because only a single speaker device must be used to listen to the sound.

In addition, when the terminal is used as a call mode function, only a single microphone device present in the terminal has to be used.

In addition, looking at the configuration of a portable terminal for providing a stereo sound patent application No. 2002-70005 already filed with the Korean Intellectual Property Office to solve the above problem, as shown in FIG. A pair of stereo speaker devices 40 and 50 are mounted in the terminal, and the pair of stereo speaker devices 40 and 50 are confronted with each other. However, since the two stereo speaker devices 40 and 50 are built in the terminal, they are located so close to each other that the stereo effect cannot be produced within the terminal, and the sound is transmitted from the inside of the terminal to the outside. If the location and direction are different, the sound transmitted to the user may be distorted. If the loudspeaker is loud, the sound may be reversed, such as echo or echo, resulting in a drop in the sound effect, and the call quality of the terminal. There was also a disadvantage of deterioration.

Accordingly, an object of the present invention is to provide a pop-up type speaker / microphone device of a portable terminal having a sub speaker / microphone device which is pulled in / out as the terminal is pressed.

Another object of the present invention is to provide a sub-speaker / microphone device that is pulled in / out in the hinge axis direction in accordance with the pressing on the terminal, the pop-up type speaker / microphone of a portable terminal to improve the stereo sound effect and microphone function of the terminal In providing a device.

In order to achieve the above object, the present invention provides a main body housing having a plurality of keys and a microphone device on the upper surface, a folder provided on the lower surface of the speaker device and the main LCD, and rotatably connected about the main body housing and the hinge axis. In the portable terminal consisting of a hinge device,
