In today's information society, people always need to call from anywhere, anytime, and they want to be able to call others. This is especially true if you have a professional need to keep in touch with others.

Also, as we can see from the explosion of vehicles, modern people are spending enormous time while driving in vehicles.

In the meantime, active studies of a system that enables the use of a telephone without being disturbed by driving as the occurrence of an accident increases due to a decrease in driver's concentration due to a driver's use of a mobile phone in a vehicle is being conducted. One of them is a hands-free system using mobile cordless phones.

1 is a schematic block diagram of a hands-free device of a conventional vehicle,

2 is a perspective view for implementing the conventional hands-free device shown in FIG.

A conventional hands free device will be described with reference to FIGS. 1 and 2.

The hands-free kit includes an earphone that outputs a received voice signal R, an ear microphone connecting an ear microphone including a microphone for acquiring a voice signal S to be transmitted and converting it into an electrical signal and a call setup / release button. A wireless telephone connection portion 34 connected to the ear microphone connection portion 22 of the mobile wireless telephone 20 having the 22 formed therein and a predetermined connection jack 34a, a microphone 44, an earphone 42, and a call setting. The ear microphone 40 including the on / off button 46 is connected so that the transmission voice signal obtained from the microphone 44 of the ear microphone 40 is output to the wireless telephone connection unit 34 and receives the input voice signal. The ear microphone connection unit 36 outputs to the earphone 42 and the received voice signal output from the radio telephone connection unit 34 according to a user's selection through the amplifier 31 and the speaker driver 33. ) Or ear The switch 38 for selectively outputting to the earphone 42 connected to the connection connection 36, the charging system 50 connected to the cigar jack 52 of the vehicle, and the received voice signal are not transmitted to the other party. It is composed of a blocking circuit 39 to prevent.

An example of use of a conventional hands-free device configured as described above will be described with reference to FIGS. 1 and 2.

First, the user connects the connection jack 34a connected to the wireless telephone connection portion 34 of the hands free kit 30 to the ear microphone connecting portion 22 of the mobile radio telephone 20, and the ear microphone connecting portion of the hands free kit 30. The ear microphone 40 is connected to the 36. When the mobile radiotelephone 20 needs to be charged, the mobile phone 20 is charged to the hands-free kit 30 for charging.

As such, when a call is received while driving while the mobile wireless telephone 20 is connected to the hands-free kit 30, the passenger presses the on / off button 46 of the call provided in the ear microphone 40, or moves. The wireless telephone 20 is operated to make a call in the state of setting the call path.

However, the conventional hands-free device for a mobile cordless telephone has a problem in that the driver's concentration is reduced because the call can be made by releasing the handle and pressing the call switch when the telephone comes while driving.

The present invention has been made in order to solve this problem, it is an object to enable the driver to talk comfortably and securely by allowing the driver to watch only the front without taking your hands off the steering wheel while driving.

It is a miniaturized and lightweight watch battery that can be used for a long time with one replacement.

On the other hand, the call switch unit is reduced in size and light weight, and can be attached to the most convenient place for the driver to be removable from the handle of the vehicle.

4 is a perspective view of a vehicle hands-free system in a preferred embodiment of the present invention.

3 and 4, the operation according to the embodiment of the present invention by the above configuration will be described.

When the call rings and the user presses the call / release switch 410 on the steering wheel, the vehicle hands-free system 1 according to the embodiment of the present invention starts to operate.

When the operation is started, the transmission IC unit 420 of the call switch unit 400 starts operation and processes the enable signal and transmits it to the embedded third antenna 430. Subsequently, the third antenna 430 transmits the enable signal transmitted from the transmitter IC unit 420 to the transmitter 200.

The first antenna 280 receives the enable signal transmitted from the third antenna 430 and transmits it to the transmission / reception IC unit 220, and the transmission / reception IC unit 220 may drive the micro switch. When the microprocessor 250 processes the driving signal and transmits the micro switch 250 to the micro switch 250, the micro switch 250 turns the circuit of the transmitter 200 into a communication state. In the call state, the first amplifier 210 of the transmitter 200 receives and amplifies the transmission signal transmitted from the three-pole jack 270 connected to the mobile wireless telephone 100 and sends it to the transmission / reception IC unit 220. In addition, the transmission / reception IC unit 220 processes the signal as a transmission signal and transmits it to the outside through the built-in first antenna 280.

The receiving IC unit 310 of the wireless earphone unit 300 receiving the transmitted signal through the second antenna 350 processes it as a voice signal and transmits it to the third amplifier 320 and a third amplifier. The audio signal transmitted to the 320 is amplified to a predetermined level and then output through the speaker 330. In addition, the user's voice is input to the microphone 240 embedded in the transmitter 200, and then the input signal is amplified to a predetermined level through the second amplifier 230, and then through the three-pole jack 270. Is sent to the mobile radiotelephone 100.

At this time, if the user presses the call / release button in the call standby state, the dialing function is performed by the redial as described above.

On the other hand, the call is terminated when the user presses the call / release switch 410 mounted on the handle is a call release operation.

The transmission IC unit 420 of the call switch unit 400 starts operation, processes the disable signal, and transmits the disabled signal to the embedded third antenna 430. Subsequently, the third antenna 430 transmits the disable signal transmitted from the transmitter IC unit 420 to the transmitter 200.

The first antenna 260 receives the disable signal transmitted from the third antenna 430 and transmits the disabled signal to the transmit / receive IC unit 220, and the transmit / receive IC unit 220 may drive the micro switch. When processing the drive signal to the micro switch 250, the micro switch turns off the circuit of the transmitter 200 to release the call and returns to the call waiting state.

In this way, the wireless earphone hands-free system for a vehicle is provided by positioning the call switch on the handle side so that the driver's gaze is fixed at the front when the call is received, when the call is ended, and when the call is to be made. It is a useful invention that allows you to make a call comfortably and safely because you can make a call by preventing the driver's concentration from distracting at the moment when starting a call.
