Abstract

The invention relates to the field of radio engineering, in particular to a radio audio transmission method and a multimedia device with radio audio transmission function. The radio audio transmission method includes: an external audio apparatus is connected with the multimedia device; the FM (frequency modulation) radio transmitting mode of the multimedia device is selected, a green indicator light is normally on; a music playing function of the audio apparatus is started, audio data are transmitted to an FM transmitting module of the multimedia device; the audio data are transmitted out by the FM transmitting module via a built-in antenna, the audio data are received by a radio, and music is played. In conclusion, according to the above radio audio transmission method, the multimedia device can communicate with a portable audio / media player or an intelligent mobile phone / iPod and the like and receives audio data transmitted from above equipment. Radio transmission sharing between the multimedia device and an audio source apparatus in a vehicular information entertainment system is realized, and life inside a vehicle of people is enriched.

Description

technical field [0001] The invention relates to the field of radio technology, in particular to a wireless audio transmission method and a multimedia device with a wireless audio transmission function. Background technique [0002] Vehicle-mounted systems refer to products that can be used in automobiles or similar sports tools, and are convenient for use in motor sports. The most common ones are vehicle-mounted MP3, MP4, GPS, DVD, vehicle-mounted power supply, and vehicle-mounted TV. The use of these vehicle-mounted products generally needs to be powered by the vehicle-mounted cigarette lighter. Vehicle-mounted products have penetrated into people's daily life and facilitated everyone's life. Cars have been used as people's daily means of transportation for 120 years. During this period, with the development of technology, cars have also undergone rapid changes. Vehicle system includes vehicle monitoring system, vehicle GPS system, 3G vehicle system, vehicle information sy...
