본 고안은 셀루라폰의 모드 절환 회로에 관한 것으로, 특히 셀루라폰의 수신신호 수신시 상황에 따라 진동모드와 링 톤(ring tone)모드를 자동으로 절환할 수 있는 셀루라폰의 자동모드 절환 회로에 관한 것이다.The present invention relates to a mode switching circuit of a cell phone, and more particularly, to an automatic mode switching circuit of a cell phone capable of automatically switching between a vibration mode and a ring tone mode according to a situation when a received signal of the cell phone is received. will be.
셀루라폰의 수신신호 수신시 사용자를 호출하는 방법으로는 진동을 일으켜서 사용자에게 이를 전달하는 진동모드와, 신호음을 발생하여 수신신호가 수신되었음을 사용자에게 알려주는 링톤모드가 있다.As a method of calling a user when receiving a received signal of the cell phone, there is a vibration mode for generating a vibration and transmitting it to the user, and a ring tone mode for generating a beep sound to notify the user that the received signal has been received.
종래 셀루라폰에는 상기와 같은 두 가지의 모드를 사용자의 편의에 따라 수동으로 절환하는 절환 스위치가 장착되어 있다.Conventional cell phone is equipped with a switch for manually switching the two modes as described above for the user's convenience.
그러나, 이와 같은 종래의 모드 절환 장치에서는 절환 스위치가 진동모드로 선택되어 있을 때, 셀루라폰을 몸에 착용하고 있지 않으면 사용자가 셀루라폰에 수신신호가 수신되었음을 알 수 없고, 또한 상기 절환 스위치가 링톤모드로 선택되어 있으면 사용자가 주변의 소음과 셀루라폰에서 울리는 호출음을 분간하지 못하는 경우가 발생하며, 조용한 곳에서는 호출음으로 인하여 주위 사람들에게 불편을 끼치는 문제점이 있었다.However, in the conventional mode switching device, when the switching switch is selected as the vibration mode, the user cannot know that the reception signal is received by the cell phone when the cell phone is not worn on the body, and the switch is ring tone If the mode is selected, the user may not be able to distinguish between the surrounding noise and the ringing sound from the cell phone, and in a quiet place, there is a problem that inconveniences to people around due to the ringing tone.
본 고안은 이와 같은 종래의 문제점을 해결하기 위하여, 셀루라폰을 몸에 부착하였을 때는 진동모드로 동작하고 그 이외에는 링톤모드로 동작할 수 있게끔 하는 자동 선택 기능을 안출한 것으로, 이를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.In order to solve such a conventional problem, the present invention devised an automatic selection function that enables the cell phone to operate in a vibration mode when the cell phone is attached to the body and other than the ring tone mode. When described in detail as follows.
제1도는 본 고안 셀루라폰의 자동 모드 절환 회로로서, 이에 도시한 바와 같이 일측을 입력전원(Vcc)에 연결하고 타측을 씨피유(CPU)(도면 미도시)에 연결한 저항(R)과, 일측을 저항(R)과 상기 씨피유(CPU)의 공통단자에 연결하고 타측을 접지에 연결한 도전체로 만들어진 고리(LNK)와, 고리와 접촉되는 셀루라폰의 뒷면에 돌출된 접촉단자(A)로 구성한 것으로, 이와 같이 구성한 본 고안의 작용 및 효과를 제2도를 참조하여 설명하면 다음과 같다.1 is an automatic mode switching circuit of the present invention cell phone, a resistor (R) connected to one side to the input power supply (Vcc) and the other side to the CPU (not shown), and one side as shown therein, It consists of a ring (LNK) made of a conductor connected to the common terminal of the resistor (R) and the CPU (CPU) and the other side connected to the ground, and a contact terminal (A) protruding on the back of the cellulaphone in contact with the ring As described above, the operation and effects of the present invention constructed as described above will be described with reference to FIG. 2.
셀루라폰이 몸에 부착되어 있을 때, 다시 말하면, 고리(LNK)를 이용하여 옷 또는 벨트에 셀루라폰을 고정시킨 상태에서 수신신호를 수신하게 되면 입력전원(Vcc)이 저항(R)을 통하여 씨피유(CPU)로 입력되므로 이 씨피유(CPU)의 입력단자에는 고전위가 나타나게 된다.In other words, when the cell phone is attached to the body, that is, when the received signal is received while the cell phone is fixed to the clothes or the belt by using the ring (LNK), the input power Vcc is connected to the C Since it is inputted as (CPU), a high potential appears at the input terminal of the CPU.
반면에, 셀루라폰이 몸에 부착되어 있지 않을 때, 다시 말하면 고리(LNK)와 고리가 접촉하는 셀루라폰의 뒷면에 설치된 접촉단자(A)가 연결되면 입력전원(Vcc)은 저항(R)과 상기 고리(LNK)를 통하여 접지로 흐르게 됨으로써 씨피유(CPU)에는 저전위가 인가된다.On the other hand, when the cellulaphone is not attached to the body, that is, when the contact terminal (A) installed on the back of the cellulphone that the ring (LNK) contacts is connected, the input power source (Vcc) is connected to the resistor (R). The low potential is applied to the CPU by flowing to the ground through the ring LNK.
이때, 씨피유(CPU)는 호출음 선택이 수동인지 자동인지를 판단하게 된다.In this case, the CPU may determine whether the ring tone selection is manual or automatic.
즉, 수동으로 설정되어 있으면 종래와 마찬가지로 진동모드일 때는 진동을 발생시키고, 링톤모드일 때는 신호음을 발생시킨다.That is, if it is set manually, vibration is generated in the vibration mode as in the conventional case, and signal tone is generated in the ring tone mode.
또한, 자동으로 설정되어 있으면, 그 씨피유(CPU)의 입력단자로 입력되는 신호의 상태를 파악하여 이 신호가 고전위이면 진동모드로 판단하고, 반대로 저전위이면 링톤모드로 판단한다.If the signal is set to automatic, the state of the signal input to the input terminal of the CPU is determined, and if the signal is high potential, it is determined as the vibration mode, and if it is low, it is determined as the ring tone mode.
이상에서 상세히 설명한 바와 같이, 종래의 수동 모드 절환 기능에, 셀루라폰을 몸에 부착하였을 때는 진동모드로 동작하고, 그 이외에는 링톤모드로 동작할 수 있게끔 하는 자동 모드 절환 회로를 추가함으로써 신호가 수신되는 것을 사용자가 쉽게 알 수 있고 주위 사람들에게 불편을 일으키지 않는 효과가 있다.As described in detail above, the signal is received by adding an automatic mode switching circuit to the conventional manual mode switching function to operate in a vibration mode when the cell phone is attached to the body and to operate in a ring tone mode. It is easy for the user to know that there is an effect that does not cause inconvenience to the people around.
