The present invention relates to a signal transmission device, and more particularly, is connected to a cigar jack socket of a vehicle, and includes a wireless communication module and an FM converter to receive a voice signal through wireless communication with an external electronic device to receive the received voice signal. The present invention relates to a signal transmission device equipped with a wireless communication module and an FM converter capable of listening to music through an external electronic device or performing a hands-free role by outputting through an audio system.

In general, a vehicle is equipped with a radio system so that an audio system can be installed to listen to various information or music transmitted from a broadcasting station, a cassette tape recorder and a CD player for listening to music contained in a cassette tape or CD.

Recently, preference has been increased for music embedded in MP3 players as well as cassette tapes and CDs. In order to listen to music embedded in MP3 players in a vehicle, sound data signals played on the MP3 player may be output from the audio system of the vehicle. It should be possible.

To this end, an FM converter which is wired to an MP3 player and receives the sound source data signal from the MP3 player as an electrical signal, converts it to an FM signal and transmits the signal to the vehicle audio device, thereby outputting the vehicle audio device. It has been done.

On the other hand, in general, when a user needs to directly operate a wireless communication means such as a mobile phone or a PDA while driving, the user cannot concentrate on driving, and the operation of the wireless communication device during driving becomes a risk factor that may cause a traffic accident.

Recently, a wireless hands-free has been devised for a mobile phone equipped with a wireless communication module. The wireless hands-free wireless communication module and the communication module of the mobile phone transmit and receive voice signals so that the driver can use the built-in speaker and microphone. You can talk to the other party without having to take your hand off the steering wheel while driving.

However, in general, wireless handsfree uses a built-in speaker so that the reception quality is inferior to that of the vehicle's built-in speaker, and in order to obtain a relatively high quality sound, the size of the handsfree may be enlarged or may be very expensive equipment. There was no.

In this way, the FM converter that allows the vehicle to listen to the sound source played on an existing external MP3 player is connected to the MP3 player via a wire, so that the external MP3 player is connected to the FM converter installed in the vehicle after boarding the vehicle. Since it has to be connected and the device must be separated at the time of getting off, the installation and removal process is cumbersome and inconvenient to use.

And the existing wireless handsfree uses a small speaker built in,

Compared to hands-free using car audio and speakers that were shipped from the factory, the company was forced to suffer relatively poor sound quality.

An object of the present invention for solving the problems according to the prior art, the wireless communication module and the FM converter for outputting an analog signal by frequency-modulating the digital voice signal and devised a device using a cigar jack to output a digital voice signal By receiving a voice signal through wireless communication with the electronic device and transmitting it as an FM signal to the vehicle's audio system through a built-in FM converter, the user can listen to sound without attaching or detaching the electronic device. The present invention provides a signal transmission device having a wireless communication module and an FM converter.

In addition, the present invention is provided with an FM converter, a microcomputer and a microphone for outputting an analog signal by frequency-modulating the wireless communication module and the digital voice signal, and the voice signal received through the wireless communication with the wireless communication module of the mobile phone passes through the FM converter. It outputs through the audio system of the vehicle and transmits the external voice input through the built-in microphone to the wireless communication module of the mobile phone by using the wireless communication module so that the voice is transmitted to the other party of the call. In addition, the present invention provides a signal transmission device equipped with a wireless communication module, an FM converter, and a microphone, which enables a high quality call by using a car audio and a speaker.

The signal transmission device having a wireless communication module and the FM converter of the present invention for solving the above technical problem relates to a signal transmission device of the cigar jack type mounted on a cigar jack socket of a vehicle equipped with an audio system, the signal transmission device A wireless communication module for communicating with a wireless communication module of an electronic device for outputting a digital voice signal, an FM converter for frequency modulating the digital voice signal received by the wireless communication module and outputting it as an analog signal, and an external signal to the signal transmission device And an external operation button to which an operation signal is input and a microcomputer to control the wireless communication module by an operation of the external operation button.

In addition, the cigar jack further includes a microphone for converting an analog voice signal into an input analog voice signal and a digital voice signal, an external control button and a microcomputer, and the voice conversion module includes an analog input through the microphone. The voice signal may be converted into a digital signal and output to the wireless communication module to be transmitted to the wireless communication module of the electronic device through the wireless communication module.

In addition, the wireless communication module is composed of a Bluetooth module or an RF module, or a dual module consisting of a Bluetooth module and an RF module. In this case, the microcomputer communicates with the wireless communication module of the electronic device. Control with one of the RF modules.
