The present invention relates to a wireless car pack capable of supplying power, and more particularly, to configure a Bluetooth chip to remove wires connected to an audio device and to supply self power to provide voice data provided by an audio reproducing device through a vehicle speaker. The present invention relates to a wireless car pack capable of outputting power.

Bluetooth technology is used for mobile terminals, personal digital assistants, personal digital terminals, smart phones, MP3 players, wireless LAN terminals, and other portable devices, various mobile devices, network access points and other peripheral devices. It is a technical specification for wireless connection at short distance within 100 meters. It is characterized by low cost and low power consumption. It uses radio frequency to transmit and receive voice and data without physical cable for communication between various digital devices. .

However, in order to utilize the Bluetooth technology as described above, self-power supply is recognized as the biggest problem.

On the other hand, due to the development of various multimedia technologies, devices that can record and listen to the sound of the original sound and users' favorite songs (CD, MD, DVD, MP3, etc.) have been developed and widely used.

Accordingly, a carpack has appeared to freely use such devices while driving in a vehicle. Carpak is a portable multimedia device, that is, a portable CD, CDP, MDP, MP3, etc., the sound source is transmitted through the car's car stereo to help you listen to music in high-performance and high-performance audio stereo sound installed in the car As a kind of converter, it is divided into a wireless carpack and a wired carpack. In the case of a wired carpack, it is generally made in the form of a cassette tape, and an earphone terminal is attached to the corner and is inserted into a car stereo of an automobile.

On the other hand, in the case of the wireless carpack is configured to enjoy the sound by plugging the earphone terminal into the multimedia device in a wireless manner by matching the frequency of the FM radio frequency and the carpack.

In addition, in the case of another car pack was equipped with a cradle for mounting a portable multimedia devices (portable CD, CDP, MDP, MP3, etc.) and was configured to receive power from the ear jack jack and cigar jack connected to the cradle.

However, in the case of the conventional car pack as described above, since the power line and the earphone line are separately provided, the wires are entangled and twisted due to twisting each other when the vehicle is installed indoors, and the management of the lines is not properly made.

Furthermore, in the related art, the charging cradle and the wireless car pack of the vehicle must be separately provided, so that the interior of the vehicle becomes more complicated and messy or the lines are twisted and entangled with each other, which adds to the inconvenience of drivers and provides expensive devices to provide the respective devices. There was a problem of investing money.

Even in the case of the wireless carpack, the earphone terminal cord connected to the carpack and the terminal cord connected to the power line were inconvenient to be entangled or twisted with each other, and since they were separate devices, it was difficult to organize the different wires separately. There was a problem that was not properly made, and because the mobile phone charging cradle and the car pack must be purchased separately, the cost is excessively spent.

Accordingly, the present invention has been made to solve the above conventional problems,

A first object of the present invention is to wirelessly receive voice data from a music playback device with Bluetooth or a GPS device with Bluetooth in a carpack configured with a Bluetooth chip to output voice data through a vehicle speaker.

In addition, a second object of the present invention is to configure a small power generation unit and a small charging unit in the car pack to operate the Bluetooth module through its own power supply.
