Smartphones are connected to the car audio system and provide services other than calls. Some smartphones (eg, iPhones) are connected to the car audio body to control or display the audio and video files of the car audio on the car audio body. However, this uses CarAudio's small / low resolution LCD panel, which is inconvenient to use and has poor service quality.

The present invention has been proposed to overcome the above problems, to utilize the high quality touch screen 202 of the smart phone 200 for the operation control and display of the car audio (100).

The car audio main body 100 communicates with the smartphone 200 so that the touch screen 202 of the smartphone can be used as it is for operation and display panel, and the car audio control application software of the smartphone 200 provides the car. It is possible to easily operate the car audio body 100 through the audio interface (GUI). In addition, it is possible to charge while the smart phone 200 is mounted on the car audio body 100, the way the body and the smartphone is connected to follow the standard standard of smartphone manufacturers.

This method makes it possible to produce the conventional car audio body 100 at a lower cost, and to utilize the high quality touch screen 202 of the smartphone at no additional cost.

The present invention provides a car audio through a car audio interface (GUI) on the touch screen 202 of the smart phone while the smart phone is connected to the outside of a car audio system with a tuner (radio), a USB host MP3 player, and a CD player. It is possible to control the operation of the main body 100, and to display the operating state of the car audio on the touch screen.

According to the present invention, the proposed system is largely composed of a car audio body 100 and a detachable smartphone 200, and the car audio body is configured without an LCD panel and a driver and operated by a mounted smartphone. The smartphone 200 allows application software for controlling the car audio body to be installed in the flash memory 203.

According to the present invention, when the smartphone is mounted on the main body, data corresponding to the position is transmitted to the car audio main body 100 according to the touch input applied to the car audio interface (GUI) opened on the touch screen 202 after the software operation. By transmitting the car audio body 100 to perform the corresponding operation. In addition, the user can listen to the data of the CD, tuner, USB (SD / MMC) of the main body, the smart phone 200, and when removed, the smart phone 200 performs its own function.

According to the present invention, when the smart phone is additionally configured to be automatically charged.

In the conventional car audio body, there is an inconvenience of controlling and displaying the operation on the front panel of a small / low resolution, but in the present invention, the user can operate by using the high resolution touch screen 202 of the smartphone as a substitute for the existing panel. There is an advantage in providing a high quality service such as convenience and listening convenience.

According to the present invention, when a smart phone is mounted, the CD, tuner, USB (SD / MMC) memory of the car audio body, and the data of the smart phone can be listened to by connecting various types of data possessed by the user with the car audio. The advantage is that you can listen.

According to the present invention, by eliminating the LCD panel and the operation driver of the car audio main body, there is an advantage that the car audio producer can reduce the production cost and the user can select a cheap car audio.

According to the present invention, when the smart phone is mounted on the car audio body, it is possible to automatically charge, thereby eliminating the need for a separate charging process for the user of the smart phone having a large amount of charge.

According to the present invention, by operating the car audio body and the smartphone in conjunction with the high-quality touch screen and the touch-type car audio application software has the advantage that can be utilized at no additional cost.

According to the present invention, by linking the car audio body and the smart phone has the advantage of providing the user with the expandability to receive free application software of the smart phone that can be provided in various ways in the future.

According to the present invention, by extending the range of use of the smart phone to the car audio system has the advantage of contributing to the market expansion of the smart phone by promoting the utilization of the smart phone as well as the utilization of the car audio.
