Recently, mobile phones, which are portable communication terminals including cellular phones and PCS phones, have become widespread, but when used while the vehicle is in use, the mobile phone reduces the driver's ability to concentrate on the road ahead, which significantly affects safe driving. Go crazy.

In other words, when using a mobile phone while driving a vehicle, the driver has to take the mobile phone by hand, which not only decreases the steering force of the steering wheel but also increases the interest in the contents of the call. In order to call, the driver's ability to focus on the front of the vehicle is reduced by manipulating a plurality of buttons installed on the mobile phone. Therefore, if the mobile phone is directly taken and used while the vehicle is in operation, it significantly affects safe driving. .

Therefore, in recent years, there is a situation in which a mobile phone is directly regulated by taking a cell phone while the vehicle is in operation. In view of this, a hands-free device for making a cell phone call possible in a vehicle has been proposed and widely used.

Such a hands-free device is generally supplied with a vehicle power and used as an operating power, and an appropriate mounting structure including a magnet for mounting a mobile phone is formed on the front thereof, and the power of the cigarette lighter is used to charge the operating power of the mobile phone and the battery. The charging connector applied as a power supply for speech is provided, and the call voice connector is connected to the call voice input / output port of the mobile phone so that the reproducing output of the call voice and the call voice to be transmitted are provided, and by the call voice connector A speaker for reproducing a call voice received from a microphone and a microphone for inputting a call voice to be delivered to a mobile phone are provided, and an earphone / microphone connection jack is provided for earphone / microphone to be communicated by a secret call function.

Therefore, when the hands-free device is used, the call voice input through the microphone in the state where the incoming call is generated is delivered to the mobile phone through the call voice connector, while the call voice is transmitted from the mobile phone to the other party. When the call voice of the other party reached is delivered to the hands-free device through the call-voice connector, the voice is reproduced through the speaker. Thus, when the hands-free device is used, the call by the mobile phone can be made without taking the mobile phone directly while the vehicle is in operation. It becomes possible.

Currently, hands-free, which is generally used, has a problem in that the mobile phone flips to receive a call when the call comes in, or the operation of the hand-free operation is hindered for a short time in order to press a call button attached to the hands-free body.

The technical problem to be achieved in the present invention is a method that can be operated by attaching a call button or a PTT switch so as to be attached to the finger or detached to the steering wheel while driving inevitably when wireless transmission and reception is inevitable. When transmitting a radio while driving, the user simply presses the transmitter call button or the PTT switch by using a part of the body to eliminate unnecessary movements, thus forming an infrared network between the wireless call button and the headset call device that do not interfere with the driver's safe operation. It is to provide a call device.
