Is connected to the data input / output terminal 103 at the bottom of the terminal 100 so as to be connected to the hands-free device 110. This type of connection not only inconveniences the user due to frequent coupling and disconnection of the connector, but may also cause poor contact of the connector. In addition, even when connected through the connector, when the incoming call to the mobile phone, the user could press the call button 101 on the terminal or open the flip 103 to make a call. This not only hassle for the user, but also lack of driving caution when driving, which can have a profound effect on safe driving.

In this regard, the present invention is proposed to solve the above-mentioned conventional problems, and an object of the present invention is to mount the electromagnet in the handsfree to make a call using the handsfree device so that the electromagnet is driven to flip the mobile communication terminal. By releasing the electronics, the user can press the call switch or open the flip, and the microphone, speaker, and amplifier can be installed in the handsfree to configure the microphone connection and the speaker connection itself. Just insert it to make a call. In some cases, a call switch may be provided outside the hands-free to determine whether to make a call based on the user's choice.

In order to achieve the above object, a wireless hands-free device for a mobile communication terminal according to the present invention includes a microphone for detecting a signal sound generated by a speaker of a mobile communication terminal, an amplifier for amplifying an output signal of the microphone, and the amplification unit. A speaker connection portion including a speaker for redirecting the output signal to sound; A frequency and sensitivity separation unit (sensor unit) for sensing the bell signal of the mobile communication terminal by receiving the output signal of the microphone; An electromagnet unit which receives an electric power from an external power source to drive the electromagnet when the sensor unit detects a bell signal to change the mobile communication terminal into a call state; A microphone connection unit including a microphone for sensing a voice signal of an external talker, an amplifier for amplifying an output signal of the microphone, and a speaker for converting the output signal of the amplifier into sound; It is characterized in that the technical configuration consisting of a power source using a vehicle power source or a battery for driving the wireless hands-free device.

Hereinafter, exemplary embodiments of the wireless hands-free device for a mobile communication terminal according to the present invention will be described with reference to the accompanying drawings.

In the present specification, as well as the preferred embodiment, further objects and effects will be more clearly understood through the following detailed description of the invention and the description of the embodiments with reference to the accompanying drawings.

The present invention relates to a wireless hands-free device for a mobile communication terminal, Figure 2 is an overall configuration diagram of a wireless hands-free device for a mobile communication terminal according to an embodiment of the present invention.

As shown in FIG. 2, a suitable embodiment of the present invention is a wireless hands-free.

When a call arrives at the mobile communication terminal 200 inserted into the device 210, a ringing tone is generated at the terminal 200. This ringing tone is detected by the speaker connection unit 220. The speaker connection unit 200 includes a microphone 221, an amplifier 222, and a speaker 223 and is disposed at a point where the speaker 201 of the inserted mobile communication terminal is located. The signal sound output from the microphone 221 of the speaker connection unit 200 is applied to the amplifier 222 while also being applied to the frequency and sensitivity separation unit 240. The frequency and sensitivity separation unit 240 detects the ringtone by the frequency difference with the voice in the incoming signal of the terminal 200 is applied. When the frequency and sensitivity separation unit 240 detects a ring tone, the light emitting diode 241 is turned on and the electromagnet 250 is driven. The electromagnet 250 is driven by the output signal of the frequency and sensitivity separation unit 240 to operate the magnet reed switch 203 in the mobile communication terminal 200 by the external magnetic formed by the electromagnet 250 to the terminal 200 ) Is converted to a call state. On the other hand, after the terminal 200 is converted to a call state, the voice signal generated outside the hands-free device 210 is applied to the microphone 202 of the mobile communication terminal through the microphone connection unit 230 and transmitted to the other party. The microphone connection unit 230 includes a microphone 231, an amplifier 232, and a speaker 233, and is disposed close to the microphone 202 of the inserted mobile communication terminal 200. The external voice signal input to the microphone 231 of the microphone connector 230 is applied to the amplifier 232. The amplified signal is converted into a voice signal through the speaker 233 and transmitted to the microphone 202 of the mobile communication terminal 200.

As described above, the wireless hands-free device according to the present invention can transmit and receive without a separate connection with the mobile communication terminal, and in particular, when receiving, it detects an incoming sound by a sensor to drive an electromagnet to automatically bring the terminal into a call state. By converting, it is much more convenient for the user.

On the other hand, the mobile terminal insertion unit 211 of the wireless hands-free device 210 can be appropriately processed according to the terminal to be inserted is irrelevant to the features of the present invention.
