Description

휴대폰의 통화대기시 전류소모 절감장치{IDLE STATE CURRENT CONSUMPTION DEVICE IN MOBILE PHONE}Reduction of current consumption during call waiting of mobile phone {IDLE STATE CURRENT CONSUMPTION DEVICE IN MOBILE PHONE}

본 발명은 휴대폰에 관한 것으로서, 특히 휴대폰의 대기시 전류소모 절감장치에 관한 것이다.The present invention relates to a mobile phone, and more particularly to a standby current consumption of the mobile phone.

통상적으로, 폴더형 휴대폰에서 폴더의 개폐 검출구성은 도 1에 도시된 바와 같이 휴대폰 본체(10)와, 폴더(12)와, 상기 휴대폰 본체(10)와 폴더(12)를 기구적으로 연결하는 힌지부(14)와, 상기 휴대폰 본체(10)에 내장되어 소정의 위치에 홀 센서(18)를 갖는 인쇄회로기판(16)과, 상기 폴더(12)에 내장되며 상기 홀 센서(18)와 대응되는 위치에 장착되는 자석(20)으로 구성된다.Typically, the opening and closing detection configuration of a folder in a folder-type mobile phone is a mechanism for connecting the mobile phone main body 10, the folder 12, the mobile phone main body 10 and the folder 12 mechanically as shown in FIG. A hinge 14, a printed circuit board 16 embedded in the mobile phone main body 10 having a hall sensor 18 at a predetermined position, and embedded in the folder 12, and having the hall sensor 18 It consists of a magnet 20 mounted at a corresponding position.

이와 같이 구성되는 폴더형 휴대폰은 도 1에 도시된 바와 같이 폴더(12)가 휴대폰 본체(10)에 닫혔을 때 자석(20)이 홀 센서(18)에 근접하여 자석(20)의 자기장 세기가 임계치 이상이 되면 스위칭 "온" 되며, 제어부로 "하이(high)"의 신호를 공급한다. 즉, 종래의 폴더형 휴대폰에서 폴더(12)의 개폐 검출방식은 폴더(12)가 휴대폰 본체(10)에 닫혀 자석(20)과 홀 센서(18)의 거리가 근접되면 스위칭 "온"되고, 폴더(12)가 휴대폰 본체(10)로부터 열려 자석(20)과 홀 센서(18)와의 거리가 폴더(12)가 휴대폰 본체(10)에 닫힌 상태보다 상대적으로 멀어지면 스위칭 "오프"되는 방식이었다.As shown in FIG. 1, when the folder 12 is closed to the mobile phone main body 10, the magnetic field strength of the magnet 20 increases when the magnet 20 approaches the hall sensor 18. When the threshold value is exceeded, the switching is turned on, and the controller supplies a high signal. That is, in the conventional clamshell cell phone, the opening / closing detection method of the folder 12 is switched on when the folder 12 is closed to the cell phone body 10 and the distance between the magnet 20 and the hall sensor 18 is close. The folder 12 was opened from the mobile phone main body 10 so that the distance between the magnet 20 and the hall sensor 18 was switched "off" when the distance of the folder 12 was relatively far from the closed state of the mobile phone main body 10. .

이때 홀 센서(18)에서 소모되는 전류가 제조업체의 스팩(SPEC)에는 1A까지 가능하다고 나와있지만 실제 휴대폰 회로에 적용했을 때는 0.3mA~0.5mA정도 소모하는 것으로 측정되었다.(자사제품모델명 "SPH-A1200"을 기준으로 한 것임.)At this time, the current consumed by the Hall sensor 18 can be as high as 1A in the manufacturer's specification (SPEC), but it was measured that it consumes about 0.3mA ~ 0.5mA when applied to the actual cell phone circuit. Based on A1200 ".)

최근 들어 휴대폰의 제어부 전류소모가 감소하면서 휴대폰 대기시의 슬립 전류(sleep current)가 2mA 이하로 줄게되었다. 이러한 이유로 홀 센서에서 소모되는 전류를 절감해야 하는 문제점이 있었다.Recently, as the control unit current consumption of the mobile phone is reduced, the sleep current during standby of the mobile phone is reduced to less than 2mA. For this reason, there is a problem in that the current consumed by the hall sensor needs to be reduced.

본 발명의 목적은 휴대폰의 통화대기시 휴대폰의 대기전류를 감소시킬 수 있는 휴대폰의 통화대기시 전류소모 절감장치를 제공하는데 있다.An object of the present invention is to provide a device for reducing the current consumption during the call standby of the mobile phone that can reduce the standby current of the mobile phone during the call standby of the mobile phone.

The folder 120 has one end connected to the mobile phone main body 100 by a hinge unit 140 to open and close in a predetermined direction from the mobile phone main body 100. The magnet 200 is switched "on" when the folder 120 is closed to the mobile phone main body 100, and is switched to "off" when the folder 120 is opened from the mobile phone main body 100. It is mounted on the hinge 140. The magnet 200 is mounted at a position corresponding to the hall sensor 180 so that the distance from the hall sensor 180 is close when the folder 120 is closed to the mobile phone main body 100, and the folder ( In the state in which the 120 is opened from the mobile phone body 100, the distance from the hall sensor 180 is configured to be farther than the state in which the folder 120 is closed to the mobile phone body 100.

상술한 바와 같이 본 발명은 폴더형 휴대폰의 대기상태 확인용 홀 센서 동작방법을 개선하여 대기시의 소모전류를 절감시키므로써, 결과적으로 휴대폰의 대기시간을 증대시킬 수 있다.As described above, the present invention improves the operation method of the hall sensor for checking the standby state of the clamshell cell phone, thereby reducing the standby current consumption, and consequently, can increase the standby time of the cellular phone.

본 발명의 실시예에 따른 폴더형 휴대폰에서는 폴더(120)의 개방시 휴대폰 본체(100)와 접히는 부분(라운드부분)에 자석(200)을 삽입하여 폴더(120)가 휴대폰 본체(100)로부터 열리면 자석(200)이 휴대폰 본체(100)에 가까워지도록 설계한다.In the folder-type mobile phone according to the embodiment of the present invention, when the folder 120 is opened from the mobile phone main body 100 by inserting the magnet 200 into a folding part (round part) when the folder 120 is opened. The magnet 200 is designed to be close to the mobile phone body 100.

본 발명은 일반적인 휴대폰의 사용환경에서 가장 긴 대기시에 폴더(120)가 닫혀있는 것에서 착안한 것으로, 본 발명의 실시예에서는 휴대폰의 홀 센서(180) 동작을 종래의 기술과 반대로 동작하도록 구성한다. 즉, 본 발명은 폴더(120)가 휴대폰에 닫힌 상태에서는 홀 센서(180)를 스위칭 "오프"시키고, 폴더(120)를 휴대폰으로부터 열면 스위칭 "온"시키도록 휴대폰의 폴더(120) 개폐에 따른 신호감지를 반대로하여 휴대폰의 대기시 소모되는 전류를 감소시키는 것이다.The present invention is conceived from the fact that the folder 120 is closed at the longest standby time in a general use environment of a mobile phone. In the embodiment of the present invention, the operation of the hall sensor 180 of the mobile phone is configured to operate in the opposite manner to the conventional technology. . That is, according to the present invention, when the folder 120 is closed on the mobile phone, the Hall sensor 180 is switched "off", and when the folder 120 is opened from the mobile phone, the switching of the folder 120 of the mobile phone is performed. Reverse the detection of the signal to reduce the current consumption of the mobile phone standby.

참고적으로 슬롯모드 동작시 폴더(120)가 휴대폰 본체(100)로부터 열린 경우 대기상태에서 평균 4.4mA의 전류소모가 있지만, 폴더(120)를 닫고서 대기하는 경우에는 4.9mA정도의 전류소모가 발생된다. 상기한 바와 같이 본 발명은 통화대기시의 전류소모를 (최대 10%까지) 개선할 수 있으며, 결과적으로 휴대폰의 통화대기시간을 증대시킬 수 있다.For reference, when the folder 120 is opened from the mobile phone main body 100 during slot mode operation, there is an average current consumption of 4.4 mA in the standby state. However, when the folder 120 is closed and waiting, the current consumption of about 4.9 mA is achieved. Is generated. As described above, the present invention can improve the current consumption during call waiting (up to 10%) and consequently increase the call waiting time of the mobile phone.

상술한 바와 같이 본 발명의 실시예에 따른 휴대폰의 통화대기시 전류소모 절감장치는 휴대폰의 통화대기시의 소모되는 전류를 감소시킬 수 있으며, 통화대기시간을 증대시킬 수 있는 효과가 있다.As described above, the current consumption reduction device during call waiting of the mobile phone according to the embodiment of the present invention can reduce the current consumed during the call waiting of the mobile phone, and can increase the call waiting time.
