Description

A device that can be called without flipping or opening a folder in a flip-up or folder-type portable phone

The present invention relates to a portable telephone terminal, and more particularly to a portable telephone terminal of the flip-up type (folder type) or folder type (folder type).

Currently, portable telephone terminals are becoming increasingly sensitive, compact, and lightweight. In addition, a bar type, a flip type, and a folder type coexist according to the shape. Among them, flip type and folder type are becoming more and more common. This flip type or folder type is popular because the flip or folder connected to the main body protects the buttons to prevent malfunctions of the buttons and collects the sound by acting as a reflector of the sound during a call. Moreover, in the flip type or the folder type, the microphone device or the speaker device can be installed in the flip or folder, which is advantageous in miniaturization.

A typical flip type portable telephone terminal is composed of a body, a flip, and a hinge device for mechanically connecting the flip to the main body so as to be openable and openable. At this time, the hinge device is a rotation axis of the flip. The flip type may be further classified into a flip-down type and a flip-up type. The flip down type is a type in which the rotation axis of the flip is installed at the bottom of the main body. The flip up type is a type in which the rotation axis of the flip is installed on the upper portion of the main body. In addition, a conventional folder type portable telephone terminal includes a main body, a folder, and a hinge device for mechanically connecting a folder to the main body so as to be openable and openable.

Among the various types as described above, the portable phone terminal of the flip up type and the folder type has a speaker device installed at the rear of the flip or folder, as well as the bar type having no flip or folder, as well as the flip down type. Accordingly, the speaker device cannot be used when the flip or folder is closed and covered by the main body. This caused the inconvenience of having to open a flip or folder to make a call. In particular, when there is an incoming call, a user often encounters a situation in which a flip or a folder is difficult to open without being prepared for the situation. In such a case, it was difficult to immediately answer the incoming call.

As described above, in the case of the flip-up type and the folder type portable telephone terminals, there is an inconvenience that a call cannot be made without opening a flip or a folder.

Accordingly, an object of the present invention is to provide a device capable of making a call without flipping or opening a folder in a flip-up type or folder type portable telephone terminal.

It should also be noted that the same elements in the figures represent the same reference signs wherever possible.

1 is a perspective view of a flip up type portable telephone terminal according to an embodiment of the present invention with the flip closed, and a flip open state of the telephone terminal of FIG. 1 is shown as a perspective view of FIG. 2. The telephone terminal shown in Figs. 1 and 2 is composed of a main body 100, a flip 102, and a hinge device 112 for mechanically connecting the main body 100 and the flip 102. The hinge device 112 is installed on both sides of the liquid crystal display (LCD) unit 104 provided in the main body 100, and the shaft of the hinge device 112 is the hinge knuckle 110 of the flip 102. It is fixed by coupling to). Herein, the LCD unit 104 only shows the display window exposed on the front surface of the main body 100, and the hinge device 112 also shows only the part visible from the outside. The flip 102 has necks 108 extending on both sides toward the hinge device 112, and hinge knuckles 110 are formed at the ends of the necks 108. In this fixed state, the flip 102 is opened and closed on the main body 100 by rotating about the rotation axis A1 shown by a dashed-dotted line.

In addition, the antenna device 106 is located at one corner of the uppermost side of the main body 100, and the LCD unit 104 is located under the antenna device 106, and buttons 114 and a keypad are located below the LCD unit 104. 116 is located. In addition, a reed switch 120 is embedded in a portion covered when the flip 102 is closed at the front of the main body 100, and a reed switch when the flip 102 is closed at the rear of the flip 102. The magnet 122 is built in a position opposite to the 120. The reed switch 120 and the magnet 122 are conventional flip open / close detection devices for detecting opening and closing of the flip 102.

And the speaker is provided with two unlike the conventional flip-up telephone terminal. As shown in FIG. 3, two speakers 118 and 124 are built in one speaker unit 130 and installed in the flip 102. The speaker unit 130 includes first and second speakers 118 and 124 and a blocking film 128. In this case, the first and second speakers 118 and 124 are installed one by one on the front and rear surfaces of the flip 102 based on the blocking film 128 so as to face opposite directions. The blocking layer 128 is formed of a material for preventing mutual interference between the first and second speakers 118 and 124. In this way, by installing the speakers on both sides of the flip 102, the voice can be output through the first speaker 118 even when the flip 102 is closed, the call is possible.

On the other hand, in the conventional flip-up type, the microphone device was installed in the lower front of the main body 100. However, when the first speaker 118 is used when the flip 102 is closed, the distance to the microphone device is shorter than when the second speaker 124 is used when the flip 102 is open. Accordingly, in order to prevent the influence between the first speaker 118 and the microphone device, in FIG. 1 and FIG. 2, the microphone device 126 is installed at one lower edge of the main body 100. In addition, it is generally known that a distance between a talker including a microphone device and a talker including a speaker device should be 14 cm or more in order to secure a distance between a user's ear and a mouth. In view of this, even if the distance between the first speaker 118 and the microphone device 126 is shortened by installing the microphone device 126 at one lower edge of the main body 100 does not interfere with the call. .

In the flip open / close detection device 132, the reed switch 120 is connected between the power supply voltage Vcc and the ground through the resistor R1, and the connection point of the reed switch 120 and the resistor R1 is a micro-processor unit (MPU). 134 is connected to the input terminal. The reed switch 120 faces the magnet 122 as shown in FIG. 2. Therefore, when the flip 102 is opened, the reed switch 120 is " off ", thereby applying a logic " high " according to the power supply voltage Vcc to the MPU 134. In contrast, when flip 102 is closed, reed switch 120 is " on " and accordingly a logic " low " according to ground is applied to MPU 134. FIG. Accordingly, the MPU 134 may check the open / closed state of the flip 102 through the flip open / close detection device 132. The MPU 134 is programmed to switch the switch 138 according to the open / closed state of the flip 102. That is, the switch 138 is connected to the first speaker 118 when the flip 102 is closed and to the second speaker 124 when the flip 102 is open. In this case, the switch 138 is connected between the voice output terminal of the vocoder 136 and the first and second speakers 118 and 124 to route the voice output paths under the control of the MPU 134 to the first and second speakers 118 and 124. To one speaker unit. The vocoder 136 encodes a voice signal input from the microphone device 126, outputs the voice data to the MPU 134, and decodes the voice data input from the MPU 134 as in a typical portable telephone terminal. (decoding) to output the audio signal to the audio output terminal.

Therefore, when the flip 102 is closed, the voice output path is connected to the first speaker 118 so that the call can be made using the microphone device 126 and the first speaker device 118. Therefore, when there is an incoming call, the user can make a call in response to the incoming call by pressing one of the buttons 114 without opening the flip 102. When the flip 102 is open, the voice output path is connected to the second speaker 124 so that a normal normal call is possible. As described above, the present invention applied to the flip up type can be similarly applied to the folder type portable telephone terminal.
